METHOD FOR TRANSMITTING PAGING EARLY INDICATION (PEI), AND TERMINAL AND NETWORK DEVICE

BACKGROUND

In order to further optimize a manner for saving energy of a terminal, a scheme based on a PEI to further save energy of the terminal is discussed. In this scheme, before the arrival of a paging occasion (PO) in each discontinuous reception (DRX) cycle (or paging cycle), a network device sends a PEI to the terminal to indicate whether the terminal receives a physical downlink control channel (PDCCH) carrying paging indication information on the PO. The terminal is waked up only when the PEI indicates that the terminal needs to receive PDCCH on a target PO; otherwise, if the PEI indicates that the terminal does not need to receive PDCCH on the target PO, the terminal will remain a sleep state to save energy. However, in this scheme based on a PEI indication, the network device needs to send the PEI to the terminal before each PO arrives, that is, one PEI is used to indicate whether the terminal receives paging indication information on one PO. As a result, the network device cannot flexibly indicate, through the PEI, whether the terminal receives paging indication information on the PO.

For ease of understanding, a communication procedure according to an embodiment of the present disclosure will be described below with reference to FIG. 2 to FIG. 5.

DRX

In order to reduce the power consumption of the terminal, there is a DRX mechanism in both LTE and NR systems, so that the terminal does not have to open a receiver all the time in a case of no data reception, but enters a state of discontinuous reception, so as to achieve the purpose of power saving. The DRX mechanism includes configuring a DRX cycle for a terminal in a radio resource control (RRC) connected state, and the DRX cycle consists of “on duration” and “opportunity for DRX”. During the on duration, the terminal monitors and receives downlink channels and signals including PDCCH. During the opportunity for DRX, the terminal does not receive downlink channels and signals such as PDCCH to reduce power consumption.

In the evolution of 5G system, higher requirements are put forward for energy saving for the terminal. For the existing DRX mechanism, in each on duration, the terminal needs to detect PDCCH constantly to determine whether the network device schedules data sent to itself. However, for most terminals, there may be no need to receive data transmission for a long time, but they still need to keep waking up regularly to monitor possible downlink transmission. The energy saving method for such terminals can be further optimized.

Therefore, in the R16 standard of 5G, an energy-saving signal is introduced to achieve further energy saving. The energy-saving signal may be used in combination with the DRX mechanism, as illustrated in FIG. 2. In this way, before entering the on duration of the DRX, the terminal may first determine whether it is necessary to receive data during the on duration of the DRX based on an indication of the energy-saving signal. When the terminal has data for transmission during a DRX cycle, the energy-saving signal “wakes up” the terminal, and accordingly, the terminal monitors PDCCH during the on duration of the DRX. On the contrary, when the terminal does not transmit data during a DRX cycle, the energy-saving signal does not “wake up” the terminal, and accordingly, the terminal does not need to monitor PDCCH during the on duration of the DRX. In this DRX mechanism combined with the energy-saving signal, if the energy-saving signal does not wake up the terminal in a DRX cycle, the terminal does not need to monitor PDCCH even in the on duration of the DRX, thus realizing energy saving.

According to the R16 standard, the energy-saving signal may be carried in a newly defined downlink control information (DCI) format 2_6. Accordingly, the network device may configure a search space set for the terminal to detect the PDCCH carrying DCI format 2_6. In the energy-saving signal, the maximum number of bits required by a single user is 6, of which 1 bit is a wake-up indication used to indicate whether the terminal needs to be woken up. The other 5 bits are a sleep indication of a secondary cell. Of course, if the energy-saving signal may carry indication bits of a plurality of terminals, it is beneficial to improve the use efficiency of transmission resources. FIG. 3 illustrates a structure of an energy-saving signal. Referring to FIG. 3, an energy-saving signal may indicate a terminal group at the same time. A wake-up indication of the terminal group may occupy a starting position of the DCI, and a sleep indication of the secondary cell of each terminal in the terminal group may occupy remaining bits in the DCI. In addition, a tail signal of the energy-saving signal is scrambled by a paging radio network temporary identity (P-RNTI). In some cases, the wake-up indication in the energy-saving signal must be included, but the number of bits occupied by the sleep indication of the secondary cell may be 0. In addition, the network device will also inform the terminal of a total number of bits of DCI and the P-RNTI used to scramble PDCCH, so that the terminal can receive the energy-saving signal correctly.

Generally, there is a mapping relationship between a monitoring occasion for PDCCH used to obtain the energy-saving signal and a time window of the on duration of the DRX on a time domain. The network device configures a time offset (PS-offset) for the terminal, which is used to determine a starting point of PDCCH monitoring occasion. After determining the starting point of PDCCH monitoring occasion, the terminal needs to further determine an ending point of PDCCH monitoring occasion, which is determined by a capability of the terminal. In a minimum time interval before the on duration of the DRX, the terminal needs to wake up the device, perform initialization after waking up and other operations, so the terminal cannot monitor the energy-saving signal in the minimum time interval before the on duration of the DRX. The minimum time interval may be shorter for a terminal with a faster processing speed, but may be long for a terminal with a slower processing speed. Table 1 shows corresponding minimum time intervals for terminals with different capabilities under the same subcarrier interval. The value 1 of the minimum time interval indicates the number of slots occupied by a minimum time interval corresponding to the terminal with a stronger capability. The value 2 of the minimum time interval indicates the number of slots occupied by a minimum time interval corresponding to the terminal with a weaker capability.

FIG. 4 illustrates a schematic diagram of a monitoring position for an energy-saving signal. Referring to FIG. 4, time domain resources occupied by the energy-saving signal takes a time domain resource indicated by a PS-offset as a starting time domain resource, and the energy-saving signal is monitored within one complete PDCCH monitoring occasion following the starting time domain resource, and the number of time domain resources between a position of a last time domain transmission unit of the time domain resources occupied by the energy-saving signal and a first of time domain resources of the on duration of the DRX is greater than the number of time domain resources included in the minimum time interval. PS-offset may be configured by the network device. In addition, the PDCCH monitoring occasion may be defined by the parameter “duration” of the PDCCH search space.

The process of receiving data by the terminal using the DRX mechanism is described above with reference to FIG. 2 to FIG. 4. For terminals in an RRC idle state, a paging message is usually received in a manner similar to the DRX mechanism. There is a paging occasion (PO) in a DRX cycle. The terminal only receives the paging message during the PO, but does not receive the paging message in a time outside the PO, so as to achieve the purpose of saving power. In addition, during the PO, the terminal may determine whether there is a paging message through detecting PDCCH scrambled by using the P-RNTI. The paging process is described below in combination with FIG. 5.

Paging Process

In an NR system, a network device may send a paging to a terminal in an RRC idle state or an RRC connected state, where the paging process may be triggered by a core network or a base station. The paging process may be used to send a paging request to a terminal in the RRC idle state, or the paging process may also be used to notify the terminal of system information update, or the paging process may also notify the terminal to receive alarm information sent by an earthquake and tsunami warning system (ETWS) and a commercial mobile alert system (CMAS).

If the paging message is initiated by the core network device, after receiving the paging message sent by the core network device, the base station will interpret contents of the paging message, obtain a tracking area identity (TAI) list of the paged terminal, and perform paging of air interface in the cell belonging to a tracking area in the list. Generally, in order to save an overhead of transmitting paging messages, after receiving the paging messages sent by the core network device, the base station may summarize paging messages corresponding to terminals with the same PO into one paging message, and finally transmit it to relevant terminals through a paging channel.

The above paging message is carried through a physical downlink shared channel (PDSCH). Before receiving the paging message, the terminal needs to receive the paging parameters through a system message, and calculate a frame number of the paging frame (PF) where the paging message is located and a PO in combination with the respective UE_ID. Then, the terminal receives paging indication information by monitoring the PDCCH scrambled by the P-RNTI within the PO on the PF, and finally receives the paging message based on the paging indication information.

The above PF represents the frame number of the system frame where the paging message should appear, and the PO represents the time when the paging message may appear. FIG. 5 illustrates a position of a PF during a DRX cycle and positions of POs within the PF. As illustrated in FIG. 5, the PF is located within the DRX cycle (or a paging cycle), and one PF may include one or more POs, and the plurality of POs may correspond to different terminals. However, for a certain terminal, during the DRX cycle (or the paging cycle), the terminal only needs to monitor its own PO.

As described above, the terminal may calculate the PF and PO based on UE_ID. In some implementations, a system frame corresponding to a system frame number (SFN) satisfying a formula (SFN+PF_offset) mod T=(T div N)*(UE_ID mod N) may be taken as a PF, and in the PF, an index i_s of the PO corresponding to the terminal may be calculated according to a formula is =floor (UE ID/N) mod Ns. T represents a cycle length of the DRX cycle of the terminal; UE_ID is used to identify the terminal; N represents the number of PFs in the DRX cycle; Ns represents the number of POs in one PF. PF_offset represents a frame offset of PF.

It should be noted that, for a terminal, if a default DRX cycle is different from a DRX cycle configured for the terminal, a cycle length of a smaller of the two DRX cycles may be selected as the above T. That is, T=min (T_UE, T_sib), where T_sib represents a cycle length of a default DRX cycle indicated in a system message, and T_UE represents a cycle length of a DRX cycle configured by the terminal. Of course, if for a terminal that is not configured with T_UE, the cycle length of the default DRX cycle indicated in the system message may be used as the value of T, that is, T=T_sib.

It should also be noted that the above UE_ID may be calculated by a formula UE ID=(5G-S-TMSI mod 1024), where 5G-S-TMSI represents a temporary mobile subscriber identity (TMSI) assigned by the communication system to the terminal.

In addition, in an NR technology, for a terminal in the RRC idle state, the network device does not know which transmit beam to be used to send a paging message for the terminal. In order to ensure that the terminal can receive the paging message, the network device sends the paging message in a manner of beam scanning. In order to support multi-beam transmission for the paging message, PO may be defined as a set of PDCCH monitoring occasions, and different PDCCH monitoring occasions correspond to paging indication information transmitted through different transmit beams. One PF may include one or more POs or starting time points of POs.

For a case where a search space identification (SearchSpaceId) of the paging search space is 0, each synchronization signal block (SSB) index corresponds to a PDCCH monitoring occasion and different SSB indexes correspond to different beams. In this way, a plurality of PDCCH monitoring occasions in a PO may be associated with transmit beams corresponding to different SSB indexes, to support multi-beam transmission of the paging message. Usually, SSBs required to complete a beam scanning constitute an “SSB burst set”.

For a case where the SearchSpaceId of the paging search space is not 0, one PO includes “S*X” consecutive PDCCH monitoring occasions, where S is the number of SSBs transmitted within the PO, which is indicated by a “ssb-PositionsInBurst” field in system information block 1 (SIB1). X represents the number of PDCCH monitoring a occasions for each SSB, which may be indicated by “nrofPDCCH-MonitoringOccasionPerSSB-InPO” field in SIB. If the parameter is not configured, X is 1. A [x*S+K]-th PDCCH monitoring occasion in a PO corresponds to a K-th actual transmitted SSB, where x=0, 1, . . . , X−1, K=1, 2, . . . , S. For example, if S=8 and X=2, a PO includes 16 PDCCH monitoring occasions, and SSB indexes corresponding to the 16 PDCCH monitoring occasions in chronological order are “0123456701234567”, in which the index numbers of the first 8 SSBs are 0-7.

Based on the above introduction, it can be seen that the terminal will adopt a manner similar to the DRX mechanism, taking the DRX cycle as a cycle, and monitoring PDCCH periodically in POs to obtain paging indication information. However, some terminals may not be paged for a long period of time, but still need to keep waking up periodically to monitor PDCCH that may carry paging indication information. The energy saving method of such terminals can be further optimized.

In order to further optimize the energy saving manner of the terminal, a scheme based on a paging early indication (PEI) to further save the terminal energy is discussed. In this scheme, the network device sends a PEI to the terminal to indicate whether the terminal receives PDCCH carrying paging indication information on the PO before the arrival of POs in each DRX cycle (or paging cycle). The terminal is waked up only when the PEI indicates that the terminal needs to receive PDCCH on the target PO. Otherwise, if the PEI indicates that the terminal does not need to receive PDCCH on the target PO, the terminal will remain asleep to save energy. However, in this scheme based on a PEI indication, the network device needs to send the PEI to the terminal before each PO arrives, that is, one PEI is used to indicate whether the terminal receives paging indication information on one PO. As a result, the network device cannot flexibly indicate, through the PEI, whether the terminal receives paging indication information on the PO.

Therefore, in order to avoid the above problems, the present disclosure provides a method of transmitting a PEI, including that the first PEI from a network device is configured to indicate whether the terminal receives paging indication information on a first PO in a first PO group, where the first PO group may include one or more POs. The method avoids that one PEI may only indicate whether the terminal receives paging indication information on one PO in the traditional PEI indication, and is conducive to improving the flexibility of the network device to indicate, through the PEI, whether the terminal receives paging indication information.

On the other hand, when the PO group includes a plurality of POs, the first PEI may indicate whether paging indication information needs to be received on the plurality of POs. The method avoids that the network device needs to send multiple PEIs to indicate whether to receive paging indication information on multiple POs in the traditional PEI indication, and is conducive to reducing the overhead of PEI transmission by the network device.

A communication method of an embodiment of the present disclosure will be described below with reference to FIG. 6. FIG. 6 is a flow diagram of a communication method provided by an embodiment of the present disclosure. The method illustrated in FIG. 6 includes operation S610.

At S610, the network device transmits a first PEI to the terminal.

The first PEI is configured to indicate whether the terminal receives paging indication information on a first PO in a first PO group. Optionally, the above first PEI is configured to indicate the terminal to receive or not to receive the paging indication information on a first PO in a first PO group. Optionally, the first PEI is configured to indicate whether the terminal needs to monitor a PDCCH carrying paging indication information on a first PO in the first PO group.

The first PO group may include one or more POs, or the first PO group may include at least one PO. The first PO group includes one PO, which may be understood as the first PEI is used to indicate one PO. The first PO group includes a plurality of POs, which may be understood as the first PEI is used to indicate the plurality of POs, and the plurality of POs may correspond to a plurality of terminals. When the plurality of POs correspond to a plurality of terminals, each terminal may calculate a respective corresponding PO based on a UE_ID of the terminal in the manner described above. For brevity, details are not repeated here. Of course, the terminals may also determine their corresponding POs based on other manners.

In some implementations, the first PEI may be carried by the PDCCH, and the monitoring occasion for the first PEI is the monitoring occasion for the PDCCH carrying the first PEI. In other implementations, the first PEI may also be carried by a reference signal, so the monitoring occasion for the first PEI is a transmission occasion for the reference signal. For example, the first PEI may be carried by a tracking reference signal (TRS), and the monitoring occasion for the first PEI is a transmission occasion for the TRS. For another example, the first PEI may be carried by a channel state information reference signal (CSI-RS), and the monitoring occasion for the first PEI is a transmission occasion for the CSI-RS. In other implementations, the first PEI may also be carried by a synchronization signal, so the monitoring occasion for the first PEI is a transmission occasion for the synchronization signal. For example, if the first PEI is carried by a secondary synchronization signal (SSS), the monitoring occasion for the first PEI is a transmission occasion for the SSS.

In the embodiments of the present disclosure, there are many grouping manners for the first PO group. For example, a PO group may be divided based on a position of a time domain resource where a PO is located, the number of POs included in the PO group, or an index of the SSB, which is used by the terminal corresponding to the PO, for time-frequency synchronization or automatic generation control (AGC). Several typical grouping manners in the embodiments of the present disclosure are described below.

A first grouping manner is to divide PO groups based on the position of the time domain resource where the PO is located.

In order to facilitate the first PEI for indication, positions of time domain resources occupied by a plurality of POs included in the first PO group may generally be relatively close. For example, the first PO group includes part or all of POs within the first PF in which the first PO is located. As another example, the first PO group includes part or all of POs in a transmission cycle of a first SSB burst set in which the first PO is located. As another example, the first PO group includes part or all of POs in a first paging cycle in which the first PO is located. As another example, the first PO group includes part or all of POs in a first DRX cycle in which the first PO is located.

It should be noted that when PO groups are divided based on the above grouping manner, the number of POs included in different PO groups among a plurality of PO groups may be different. Of course, in some cases, different PO groups in the plurality of PO groups may include a same number of POs.

Of course, in the embodiments of the present disclosure, the POs in the first PO group may also be located in a plurality of different PFs, or the number of PFs in which the POs in the first PO group is located is M, where M is a positive integer greater than 1. For example, the PFs in which the POs in the first PO group are located include a first PF and a second PF, where the first PF and the second PF are different PFs.

The POs in the first PO group may also be located in a plurality of different SSB burst sets, or the number of SSB burst sets in which the POs in the first PO group is located is P, where P is a positive integer greater than 1. For example, the SSB burst sets of the POs in the first PO group includes a first SSB burst set, a second SSB burst set and a third SSB burst set, where the first SSB burst set, the second SSB burst set and the third SSB burst set are different SSB burst sets.

The POs in the first PO group may also be located in a plurality of different paging cycles, or the number of paging cycles in which the POs in the first PO group is located is Q, where Q is a positive integer greater than 1. For example, the paging cycles of the POs included in the first PO group includes a first paging cycle, a second paging cycle, a third paging cycle and a fourth paging cycle, where the first paging cycle, the second paging cycle, the third paging cycle and the fourth paging cycle are different paging cycles.

The POs in the first PO group may also be located in different DRX cycles, or the number of DRX cycles in which the POs in the first PO group is located is K, where K is a positive integer greater than 1. For example, the DRX cycles of the POs included in the first PO group includes a first DRX cycle, a second DRX cycle and a third DRX cycle, and the first DRX cycle, the second DRX cycle and the third DRX cycle are different DRX cycles.

A second grouping manner is to divide a PO, which corresponds to a terminal performing time-frequency synchronization and/or AGC based on the same SSB burst set, into a PO group.

Typically, there may be a plurality of POs after an SSB burst set, or there may be a plurality of POs between two adjacent SSB burst sets. Then, the plurality of POs between two adjacent SSB burst sets may be divided into a PO group, or a PO corresponding to a terminal that performs time-frequency synchronization and/or AGC based on the same SSB burst set may be divided into a PO group.

A third grouping manner is to divide PO groups based on the number of POs included in the PO groups.

That is, the first PO group is one of a plurality of PO groups, and different PO groups in the plurality of PO groups include a same number of POs.

It should be noted that in the case of dividing PO groups based on the above third grouping manner, there may be a case that POs included in a PO group belong to different PFs. For example, it is assumed that PF1 includes 3 POs, PF2 includes 2 POs, and the number of POs included in the PO group is 2. Then, the two POs included in PO group 1 may be the first two POs on PF1, and the two POs included in PO group 2 are the last PO on PF1 and the first PO on PF2, respectively. Of course, similar to the above, in the case of dividing PO groups based on the above third grouping manner, there may be a case that POs included in one PO group belong to different SSB burst sets. Optionally, in the case of dividing PO groups based on the above third grouping manner, there may be a case that POs included in one PO group belong to different paging cycles. Optionally, in the case of dividing PO groups based on the above third grouping manner, there may be a case that POs included in one PO group belong to different DRX cycles.

In some implementations, the number of POs included in the PO group may be pre-configured by the network device. Of course, the number of POs included in the PO group is also predefined by protocol, and the embodiments of the present disclosure are not limited thereto.

A fourth grouping manner is to divide PO groups based on the number of POs included in the PO group, and a position of a time domain resource where a PO is located.

That is, the first grouping manner and the third grouping manner may be used in combination. However, to prevent conflicts, a priority between the two factors may be set. In some implementations, it is assumed that a factor of the position of the time domain resource where the PO is located has a higher priority than a factor of the number of POs included in the PO group, relevant provisions for the number of POs included in the PO group are not always satisfied in a case that relevant provisions for the position of the time domain resource where the PO is located are satisfied.

For example, the relevant provisions for the position of the time domain resource where the PO is located are as follows: POs in the PO group belong to the same PF. In addition, the related provisions for the number of POs included in the PO group are as follows: the number of POs included in the PO group is 4. If PF1 includes 7 POs, these 7 POs may be divided into 2 PO groups: PO group 1 and PO group 2. The first 4 POs within PF1 may be included in PO group 1, and the last 3 POs within PF1 may be included in PO group 2. In this case, the number of POs in PO group 2 does not meet that the number of POs included in PO group is 4.

In other implementations, it is assumed that the position of the time domain resource where the PO is located has a lower priority than that of the number of POs included in the PO group, the relevant provisions for the position of the time domain resource where the PO group is located are not always satisfied in the case that the relevant provisions for the number of POs included in the PO group are satisfied.

For example, the relevant provisions for the position of the time domain resource where the PO is located are as follows: POs in the PO group belong to the same PF. The relevant provisions for the number of POs included in the PO group are as follows: the number of POs included in the PO group is 3. If PF1 includes 5 POs, that is, PO1˜PO5, and PF2 includes one PO, that is, PO6. Then the above 6 POs (i.e., PO1˜PO6) may be divided into PO group 1 and PO group 2. The first 3 POs in PF1, i.e. PO1 to PO3, may be included in PO group 1, and PO4 and PO5 in PF1 and PO6 in PF2 may be included in PO group 2. In this case, the position of the time domain resource where the PO group is located in the PO group 2 does not belong to the same PF, that is, the relevant regulations for the position of the time domain resource where the PO group is located are not satisfied.

Of course, in the embodiments of the present disclosure, in addition to divide PO groups in advance based on some parameters, PO groups may also be formed naturally based on the transmission manner of PEI.

That is, POs located within a target time domain resource belong to the first PO group, the target time domain resource is a time domain resource region between a second time domain resource corresponding to the first PEI and a third time domain resource corresponding to a second PEI, and the second PEI is a next PEI, sent after the first PEI, among a plurality of PEIs.

In some implementations, the second time domain resource corresponding to the first PEI is a last time domain unit in a first guard interval, and the first guard interval is a guard interval located after a time domain resource occupied by transmitting the first PEI, and/or the third time domain resource corresponding to the second PEI is a last time domain unit in a second guard interval, and the second guard interval is a guard interval located after a time domain resource occupied by transmitting the second PEI.

It should be noted that the above time domain unit may be understood as a unit used for dividing time domain resources. In some implementations, the above time domain unit may be a minimum time domain unit used for dividing time domain resources, for example, a time domain symbol. Of course, the above time domain unit may also be other time domain units used for dividing time domain resources, for example, a slot, a subframe and the like.

In other embodiments, the second time domain resource may also be a first of time domain resources for transmitting the first PEI, and the third time domain resource may also be a first of time domain resources for transmitting the second PEI. Of course, the second time domain resource may also be a last time domain resource for transmitting the first PEI, and the third time domain resource may also be a last time domain resource for transmitting the second PEI. The following takes the scenario of transmitting PEIs periodically as an example, the division of PO groups will be introduced in combination with FIG. 12. For brevity, details are not repeated here.

It should be noted that in the division manner of PO groups described above, for convenience of understanding, one PO group including a plurality of POs is taken as an example. However, in the embodiments of the present disclosure, one PO group may also include only one PO, and the PO groups may be divided in the same manner as when the PO group includes a plurality of POs, as described above in detail. For brevity, details are not repeated here.

In some cases, the terminal is in an RRC idle state, and the network device cannot determine which transmit beam to be used to transmit the PEI. Therefore, in order to improve a possibility that the terminal has received the PEI, the network device may send the first PEI to the terminal in a manner of beam scanning. Since the manner of beam scanning is usually implemented in a manner of time division multiplexing in the current communication system, when the first PEI is transmitted in the manner of beam scanning, the time unit occupied by the first PEI may be a collection of a plurality of time units, where different time units in the plurality of time units may correspond to different beams. Therefore, in the embodiments of the present disclosure, the first PEI may also be referred to as a “first PEI burst set”. Of course, in the embodiments of the present disclosure, for a communication system that does not support multi-beam technology, the network device may also adopt a wider beam to transmit the first PEI. At this time, the time domain resource occupied by transmitting the first PEI may be one time unit.

It should be noted that in the embodiments of the present disclosure, a size of the time domain resources occupied by transmitting the first PEI may be fixed. In some implementations, the fixed size described above may be predefined or may be configured by the network device. Of course, in other embodiments, the above size of the time domain resources occupied by transmitting the first PEI may be varied. For example, the size of the time domain resources occupied by transmitting the first PEI may be indicated by the network device.

As described above, when the network device sends the first PEI, the terminal may be in the opportunity for DRX. In order to receive the first PEI, the terminal needs to first determine a first time domain resource occupied by transmitting the first PEI, and receive the first PEI sent by the network device on the first time domain resource.

If a transmission position of the PEI is associated with each PO according to a prior manner, in the case that the first PO group includes a plurality of POs in the embodiments of the present disclosure, in order to make time domain resources for transmitting the PEI, which are calculated by each terminal based on a respective corresponding PO, the same, it is necessary to configure the independent calculation manners for different terminals, which increases the complexity of the mapping relationship between the PO and the PEI.

Therefore, in order to avoid the above problems, the present disclosure also provides a method to determine the time domain resources occupied by transmitting the first PEI. That is, a positional relationship between the first time domain resource and the time domain resources occupied by the first PO group may be established. Thus, the network device may determine the first time domain resource based on time domain resources occupied by the first PO group and a positional relationship between time domain resources occupied by PO groups and time domain resources occupied by transmitting PEIs. Accordingly, the terminal may also determine the first time domain resource based on time domain resources occupied by the first PO group and a positional relationship between time domain resources occupied by PO groups and time domain resources occupied by transmitting PEIs. Of course, this manner of determining the time domain resources occupied by transmitting the first PEI is also applicable to a scenario where only one PO is included in the first PO group. For the sake of brevity, the following mainly takes a PO group including multiple POs as an example.

It should be noted that the time domain resources occupied by the first PO group may be understood as continuous time domain resources, and in this continuous time domain resources, only part of the time domain resources may be time domain resources corresponding to POs in the first PO group. Time domain resources occupied by the PO group in the embodiments of the present disclosure are described below with reference to FIG. 7. Referring to FIG. 7, the first PO group includes PO1, PO2 and PO3, where a time domain resource occupied by PO1 is time domain resource 1, a time domain resource occupied by PO2 is time domain resource 2, and a time domain resource occupied by PO3 is time domain resource 3. Positions of time domain resource 1, time domain resource 2 and time domain resource 3 in the time domain are that a position of time domain resource 1 in the time domain is earlier than that of time domain resource 2 in the time domain, a position of time domain resource 2 in the time domain is earlier than that of time domain resource 3 in the time domain, and time domain resource 1 and time domain resource 2 are continuous resources in the time domain, and time domain resource 2 and time domain resource 3 are separated by two time domain units in the time domain. At this time, the time domain resource occupied by the above PO group is continuous time domain resources, and a starting position of the continuous time domain resources may be a starting position of the time domain resource 1 in the time domain, and an ending position of the continuous time domain resources may be an ending position of the time domain resource 3 in the time domain.

In some implementations, the positional relationship between the time domain resources occupied by the PO groups and the time domain resources occupied by transmitting PEIs may be represented by a first offset value. Of course, the above positional relationship may also be calculated by a formula. Embodiments of the present disclosure are not limited thereto. Several possible setting manners of the first offset value in the embodiments of the present disclosure are described below. For ease of illustration, “a reference time domain resource” is used below to indicate time domain resources occupied by a PO group.

According to setting manner 1, the reference time domain resource is a starting time domain symbol in time domain symbols where any PO in the PO group is located. Accordingly, the first offset value is an offset value between the reference time domain resource and time domain resources occupied by transmitting the PEI.

Any one of the above PO group may include a first PO in the PO group, or a last PO in the PO group, and of course, may be a certain PO in the PO group. Embodiments of the present disclosure are not limited thereto.

The time domain resources occupied by transmitting the PEI may include a first time domain resource in the time domain resources occupied by transmitting the PEI. The time domain resources occupied by transmitting the PEI may also be a last time domain resource in the time domain resources occupied by transmitting the PEI. Of course, the time domain resources occupied by transmitting the PEI also may be any one of the time domain resources occupied by transmitting the PEI. Embodiments of the present disclosure are not limited thereto.

The above time domain resource may be any transmission unit in the time domain, which is not limited by the embodiments of the present disclosure. For example, the time domain resource may be a subframe, the time domain resource may also be a frame, the time domain resource may also be a slot, and the time domain resource may also be a time domain symbol.

It should be noted that in some cases, “time domain resources occupied by transmitting the PEI” above are resources actually occupied by transmitting the PEI. In other cases, “time domain resources occupied by transmitting the PEI” above may not be the resources actually occupied by transmitting the PEI, but may only be the resources related to the time domain resources occupied by transmitting the PEI. For example, when the above time domain resources are frames, the time domain resources occupied by transmitting the PEI may be understood as the frames occupied by transmitting the PEI, and the time domain resources actually occupied by transmitting the PEI may not occupy a starting position of the frames. At this time, if the first offset value is an offset value between the reference time domain resource and the starting position of the frames occupied by transmitting the PEI, the time domain resources occupied by transmitting the PEI are not actual time domain resources for really transmitting the PEI. Of course, when the above time domain resources are subframes or slots, a similar situation will occur. In addition, based on similar scenarios, the above reference time domain resource may be a time domain resource related to the time domain resources occupied by the PO group, and are not a real time domain resource occupied by the PO group.

The position of the reference time domain resource may be specified by the network device or may be predefined by protocol. Embodiments of the present disclosure are not limited thereto.

In combination with FIG. 8, a setting manner of the first offset value of the embodiments of the present disclosure is described by taking that a time domain resource occupied by transmitting the PEI is a starting time domain symbol for transmitting the PEI and the reference time domain resource is a starting time domain symbol occupied by PO2 as an example.

Referring to FIG. 8, it is assumed that the PO group includes 4 POs, and a position order of these 4 POs in the time domain is: a time domain symbol occupied by PO1 is earlier than that occupied by PO2, a time domain symbol occupied by PO2 is earlier than that occupied by PO3, and a time domain symbol occupied by PO3 is earlier than that occupied by PO4. The reference time domain resource is a starting time domain symbol of PO2 in the PO group. The starting time domain symbol for transmitting the PEI is time domain symbol 1. Then, the first offset value is an offset value between reference time domain symbol SO and time domain symbol 1. Optionally, the first offset value is equal to the number of time domain symbols between the reference time domain symbol SO and the time domain symbol 1.

According to setting manner 2, the reference time domain resource is a starting position of a slot where any PO in the PO group is located. Accordingly, the first offset value is an offset value between the reference time domain resource and time domain resources occupied by transmitting the PEI.

It should be noted that in some cases, “time domain resources occupied by transmitting the PEI” above are resources actually occupied by transmitting the PEI. In other cases, “time domain resources occupied by transmitting the PEI” above may not be the resources actually occupied by transmitting the PEI, but may only be the resources related to the time domain resources occupied by transmitting the PEI. For example, when the above time domain resource are frames, the time domain resources occupied by transmitting the PEI may be understood as the frames occupied by transmitting the PEI, and the time domain resources actually occupied by transmitting the PEI may not occupy a starting position of the frames. At this time, if the first offset value is an offset value between the reference time domain resource and the starting position of the frames occupied by transmitting PEIs, the time domain resource occupied by transmitting the PEI are not actual time domain resources for really transmitting the PEI. Of course, when the above time domain resources are subframes or slots, a similar situation will occur. In addition, based on similar scenarios, the above reference time domain resource may be a time domain resource related to the time domain resources occupied by the PO group, and are not a real time domain resource occupied by the PO group.

The position of the reference time domain resource may be specified by the network device or may be predefined by protocol. Embodiments of the present disclosure are not limited thereto.

According to setting manner 3, the reference time domain resource is a starting position of a subframe where any PO in the PO group is located. Accordingly, the first offset value is an offset value between the reference time domain resource and time domain resources occupied by transmitting the PEI.

It should be noted that in some cases, “time domain resources occupied by transmitting the PEI” above are resources actually occupied by transmitting the PEI. In other cases, “time domain resources occupied by transmitting the PEI” above may not be the resources actually occupied by transmitting the PEI, but may only be the resources related to the time domain resources occupied by transmitting the PEI. For example, when the above time domain resource is are frames, the time domain resources occupied by transmitting the PEI may be understood as the frames occupied by transmitting the PEI, and the time domain resources actually occupied by transmitting PEIs may not occupy a starting position of the frames. At this time, if the first offset value is an offset value between the reference time domain resources and the starting position of the frames occupied by transmitting the PEI, the time domain resource occupied by transmitting the PEI are not actual time domain resources for really transmitting the PEI. Of course, when the above time domain resources are subframes or slots, a similar situation will occur. In addition, based on similar scenarios, the above reference time domain resource may be a time domain resource related to the time domain resources occupied by the PO group, and are not a real time domain resource occupied by the PO group.

The position of the reference time domain resource may be specified by the network device or may be predefined by protocol. Embodiments of the present disclosure are not limited thereto.

According to setting manner 4, the reference time domain resource is a starting position of a frame where any PO in the PO group is located. Accordingly, the first offset value is an offset value between the reference time domain resource and time domain resources occupied by transmitting the PEI.

It should be noted that in some cases, “time domain resources occupied by transmitting the PEI” above are resources actually occupied by transmitting the PEI. In other cases, “time domain resources occupied by transmitting the PEI” above may not be the resources actually occupied by transmitting the PEI, but may only be the resources related to the time domain resources occupied by transmitting the PEI. For example, when the above time domain resource are frames, the time domain resources occupied by transmitting the PEI may be understood as frames occupied by transmitting the PEI, and the time domain resources actually occupied by transmitting the PEI may not occupy a starting position of the frames. At this time, if the first offset value is an offset value between the reference time domain resource and the starting position of the frames occupied by transmitting the PEI, the time domain resource occupied by transmitting PEIs are not actual time domain resources for really transmitting the PEI. Of course, when the above time domain resources are subframes or slots, a similar situation will occur. In addition, based on similar scenarios, the above reference time domain resource may be a time domain resource related to the time domain resources occupied by the PO group, and are not a real time domain resource occupied by the PO group.

The position of the reference time domain resource may be specified by the network device or may be predefined by protocol. Embodiments of the present disclosure are not limited thereto.

According to setting manner 5, the reference time domain resource is a starting time domain symbol in time domain symbols occupied by the PO group. Accordingly, the first offset value is an offset value between the reference time domain resource and time domain resources occupied by transmitting the PEI.

The time domain resources occupied by transmitting the PEI may include a first time domain resource in the time domain resources occupied by transmitting the PEI. The time domain resource occupied by transmitting the PEI may also be a last time domain resource in the time domain resources occupied by transmitting the PEI. Of course, the time domain resources occupied by transmitting the PEI also may be any one of the time domain resources occupied by transmitting the PEI. Embodiments of the present disclosure are not limited thereto.

It should be noted that in some cases, “time domain resources occupied by transmitting the PEI” above are resources actually occupied by transmitting the PEI. In other cases, “time domain resources occupied by transmitting the PEI” above may not be the resources actually occupied by transmitting the PEI, but may only be the resources related to the time domain resources occupied by transmitting the PEI. For example, when the above time domain resource are frames, the time domain resources occupied by transmitting the PEI may be understood as the frames occupied by transmitting the PEI, and the time domain resource actually occupied by transmitting the PEI may not occupy a starting position of the frames. At this time, if the first offset value is an offset value between the reference time domain resource and the starting position of the frames occupied by transmitting PEIs, the time domain resources occupied by transmitting the PEI are not actual time domain resources for really transmitting the PEI. Of course, when the above time domain resources are subframes or slots, a similar situation will occur.

The position of the reference time domain resource may be specified by the network device or may be predefined by protocol. Embodiments of the present disclosure are not limited thereto.

In combination with FIG. 9, a setting manner of the first offset value of the embodiments of the present disclosure is described by taking that a time domain resource occupied by transmitting the PEI is a starting time domain symbol for transmitting the PEI and the reference time domain resource is a starting time domain symbol occupied by the PO group as an example. Referring to FIG. 9, it is assumed that the PO group consists of four POs: PO1, PO2, PO3, and PO4. A starting time domain symbol occupied by the PO group is reference time domain symbol SO. The starting time domain symbol for transmitting the PEI is time domain symbol 2. Then, the first offset value is an offset value between reference time domain symbol SO and time domain symbol 2. Optionally, the first offset value is equal to the number of time domain symbols between the reference time domain symbol SO and the time domain symbol 2.

According to setting manner 6, the reference time domain resource is a time domain resource at Y/x position in time domain symbols occupied by the PO group. Accordingly, the first offset value is an offset value between the reference time domain resource and time domain resources occupied by transmitting the PEI.

The above x represents the total number of time domain resources occupied by the PO group, and y is a positive integer less than or equal to x. For example, referring to FIG. 10, it is assumed that a time domain resource occupied by transmitting the PEI is a starting time domain resource in the time domain resources occupied by transmitting the PEI, the number of time domain symbols x occupied by the PO group is 5, and the value of y is 1. A starting time domain symbol in the time domain symbols occupied by the PO group is time domain symbol 1, a last time domain symbol in the time domain symbols occupied by the PO group is time domain symbol 5, and time domain symbols occupied by the PO group are numbered sequentially between the time domain symbol 1 and the time domain symbol 5. Then, the reference time domain resource is a time domain symbol at position ⅕ of the time domain symbols occupied by the PO group, that is, the reference time domain resource is at the ending position of time domain symbol 1.

The time domain resources occupied by transmitting the PEI may include a first time domain resource in the time domain resources occupied by transmitting the PEI. The time domain resource occupied by transmitting the PEI may be a last time domain resource in the time domain resources occupied by transmitting the PEI. Of course, the time domain resource occupied by transmitting the PEI may be any one of the time domain resources occupied by transmitting the PEI. Embodiments of the present disclosure are not limited thereto.

The time domain resource may be any type of transmission unit in the time domain, which is not limited by the embodiments of the present disclosure. For example, the time domain resource may be a subframe, or the time domain resource may be a frame, or the time domain resource may be a slot, and the time domain resource may also be a time domain symbol.

The position of the reference time domain resource may be specified by the network device or may be predefined by protocol. Embodiments of the present disclosure are not limited thereto.

The above first offset value may be specified by the network device or may be predefined by protocol. Embodiments of the present disclosure are not limited thereto. In addition, the time domain unit of the first offset value may be any time domain transmission unit, for example, a subframe, a time domain symbol, a slot, etc.

The relationship between the time domain resources occupied by the PO group and the first offset value is introduced above in combination with the setting manners 1 to 6 of the first offset value. Based on the above introduction, it can be seen that each PO group may correspond to one first offset value in the embodiments of the present disclosure. Accordingly, the terminal may receive the first PEI based on the length of the time domain resources occupied by transmitting the first PEI and the first PEI.

In other embodiments, a plurality of offset values may also be configured for each first PEI, where the plurality of offset values may include a starting offset value and an ending offset value, the starting offset value is a value between the reference time domain resource and a starting position of the time domain resources occupied by transmitting the PEI, and the ending offset value is an offset value between the reference time domain resource and an ending position of the time domain resources occupied by transmitting the PEI. Accordingly, the terminal may determine the resources occupied by transmitting the first PEI based on the starting offset value and the ending offset value.

Of course, in other embodiments, each PO group may also correspond to a plurality of first offset values to improve the reliability for the terminal receiving the first PEI. It is assumed that the first PO group may correspond to first offset value 1 and first offset value 2, where a time domain resource corresponding to the first offset value 1 is earlier than a time domain resource corresponding to the first offset value 2. Accordingly, the network device sends the first PEI on the time domain resource corresponding to the first offset value 1 and the first PEI on the time domain resource corresponding to the first offset value 2. Thus, the terminal may receive the first PEI on the time domain resource corresponding to the first offset value 1 and on the time domain resource corresponding to the first offset value 2, respectively, so as to avoid the terminal not receiving the first PEI on the time domain resource corresponding to the first offset value 1, which leads to the terminal being unable to determine whether it is waked up or not.

Of course, in the embodiments of the present disclosure, even if one PO group may correspond to a plurality of first offset values, the terminal may determine whether it is necessary to receive the first PEI on the time domain resources corresponding to the plurality of first offset values based on its own capability, PEI reception situation and other factors. In some cases, if the terminal has a stronger capability, the terminal may receive the first PEI only on a time domain resource corresponding to one of a plurality of first offset values. On the contrary, if the terminal has a weaker capability, the terminal may receive the first PEI on time domain resources corresponding to a plurality of first offset values. Of course, the embodiments of the present disclosure are not specifically limited to this. For a terminal with stronger capability, the terminal may also receive the first PEI on time domain resources corresponding to the plurality of first offset values. The terminal with weaker capability may also receive the first PEI only on a time domain resource corresponding to one first offset value.

As described above, the terminal also monitors paging indication information periodically on the POs according to the paging cycle (or DRX cycle). Therefore, in order to further improve the energy saving effect of the terminal, the network device may also send the first PEI periodically to indicate whether the terminal needs to receive the paging indication information on the POs. In some implementations, the first PEI may be configured with an independent transmission cycle for transmitting periodically. For example, the first PEI may be configured with a first cycle, and accordingly, the first PEI may be transmitted periodically with a cycle of the first cycle. In other implementations, the configured cycle may also be multiplexed to transmit the first PEI periodically. For example, a transmission cycle of the SSB burst set may be multiplexed to transmit the first PEI periodically. The following will be described in detail in combination with FIG. 13 to FIG. 15, and will not be repeated here for the sake of brevity.

In a scheme in which the first PEI is transmitted periodically according to a first cycle, the first PEI may be transmitted on a fixed time domain resource within the first cycle, so that the terminal can determine the first time domain resource occupied by transmitting the first PEI based only on the first cycle. For example, it is assumed that the first PEI is fixed for transmission on a first of time domain symbols of each cycle, accordingly, the terminal may determine the time domain resource occupied by transmitting the first PEI, i.e. a starting time domain symbol within the first cycle, based on a cycle length of the first cycle.

The first cycle may be predefined based on the protocol or may be pre-configured by the network device. In addition, a unit of the first cycle may be any kind of time domain unit, for example, a time domain symbol, a slot, a subframe, a frame, a millisecond, a second, etc.

Of course, in some cases, we want to improve the flexibility of the time domain resource occupied by the first PEI in the scenario where the first PEI is transmitted periodically. Accordingly, a second offset value may be set to indicate a position of the time domain resource occupied by the first PEI in each cycle, and accordingly, the time domain position of the time domain resource occupied by the first PEI in the first cycle is adjusted by adjusting the size of the second offset value.

In some implementations, the second offset value may be an offset value between a time domain resource occupied by transmitting the first PEI and a starting time domain resource in the first cycle. The second offset value may be an offset value between a time domain resource occupied by transmitting the first PEI and a last time domain resource in the first cycle. The second offset value may be understood as an offset value between a time domain resource occupied by transmitting the first PEI and any time domain resource in the first cycle. Embodiments of the present disclosure are not limited to the manner of determining the second offset value.

The time domain resources occupied by transmitting the PEI may include a first time domain resource in the time domain resources occupied by transmitting the PEI. The time domain resources occupied by transmitting the PEI may be a last time domain resource in the time domain resources occupied by transmitting the PEI. Of course, the time domain resources occupied by transmitting the PEI may be any one of the time domain resources occupied by transmitting the PEI. Embodiments of the present disclosure are not limited thereto.

The time domain resource may be any transmission unit in the time domain, which is not limited by the embodiments of the present disclosure. For example, the time domain resource may be a subframe, or the time domain resource may be a frame, or the time domain resource may be a slot, and the time domain resource may also be a time domain symbol.

The second offset value may be indicated to the terminal by the network device. Of course, the second offset value is also predefined by protocol, and the embodiments of the present disclosure are not limited thereto. In addition, the time domain unit of the second offset value may be any time domain transmission unit, for example, a subframe, a time domain symbol, a slot, etc.

A transmission manner of PEI according to the embodiments of the present disclosure is described below with reference to FIG. 11 and FIG. 12. It should be noted that the “first PEI” above may be understood as one PEI among a plurality of PEIs transmitted periodically below.

Referring to FIG. 11, it is assumed that the network device 110 transmits the PEIs periodically with cycle 1 as the first cycle. During each cycle 1, the network device 110 transmits the PEIs to the terminal 120 in a beam scanning manner through 5 transmit beams 510. As mentioned above, the PEIs may also be called “PEI burst set” at this time.

Referring to FIG. 12, it is assumed that time domain resources 1 to 12 are arranged in sequence from early till late in the time domain. In addition, the network device configures the terminal to transmit PEIs periodically according to cycle 2. The network device will occupy a starting time domain resource of each cycle to transmit PEIs. At this time, time domain resource 1 occupied by a k-th PEI sent by the network device includes a starting time domain resource of a k-th cycle, time domain resource 5 occupied by a (k+1)-th PEI sent by the network device includes a starting time domain resource of a (k+1)-th cycle, and time domain resource 9 occupied by a (k+2)-th PEI sent by the network device includes a time domain resource symbol of a (k+2)-th cycle.

In addition, a time domain resource in which PO1 is located is time domain resource 2. A time domain resource in which PO2 is located is time domain resource 3. A time domain resource in which PO3 is located is time domain resource 4. A time domain resource in which PO4 is located is time domain resource 7. Time domain resources in which PO5 is located are time domain resource 8 and time domain resource 9. Time domain resources in which PO6 is located are time domain resource 6 and time domain resource 10. Moreover, PO1 only occupies a second half of time domain resource 2, and there is a guard interval 1 between a starting time domain resource occupied by PO1 and a last time domain resource occupied by the k-th PEI. PO6 occupies only a second half of the time domain resource 9, and there is no guard interval 2 between a starting time domain resource occupied by PO6 and a last time domain resource occupied by the (k+2)-th PEI.

In the above case, according to the scheme of PO group formed naturally described above, POs occupying time domain resources between the time domain resource 1 and the time domain resource 5 may form the PO group 1 naturally, and whether a paging indication message needs to be received on the POs within the PO group 1 is indicated by the k-th PEI. That is, PO Group 1 includes PO1, PO2, and PO3.

Since there is no guard interval 2 between the time domain resource occupied by PO6 and the time domain resource occupied by the (k+2)-th PEI, if the (k+2)-th PEI is used to indicate whether the terminal receives the paging indication message on PO6, the terminal may be processing the (k+2)-th PEI at this time, and it is too late to determine whether the paging indication message needs to be received on PO6. Therefore, in order to avoid the above situation, whether the terminal needs to receive the paging indication message on the PO6 may be indicated by the (k+1)-th PEI. At this time, whether the terminal needs to receive the paging indication message on PO4, PO5 and PO6 may be indicated by the (k+1)-th PEI, and accordingly, PO4, PO5 and PO6 form PO group 2 naturally.

As described above, a transmission cycle of the PEI may also be a transmission cycle of a multiplexed SSB burst set. However, in some cases, the transmission cycle of SSB burst set may be shorter, while PEI transmission does not need such a short transmission cycle. Therefore, the embodiments of the present disclosure also designs a parameter of “a transmission density for the PEI” to adjust a transmission frequency for the PEI. The transmission density for the PEI being N indicates that the PEI is transmitted once every N transmission cycles of the SSB burst set, and N is a positive integer.

Accordingly, the operation that the terminal determines the first time domain resource occupied by transmitting the first PEI may include that: the terminal determines the first time domain resource based on a transmission cycle of an SSB burst set, a third offset value and a transmission density for a PEI, where the third offset value is configured to determine a time domain resource position of the first time domain resource in the transmission cycle.

In some implementations, the third offset value may be an offset value between a target time domain resource and a starting time domain resource in the time domain resources occupied by transmitting the SSB burst set. The third offset value also may be an offset value between the target time domain resource and a last time domain resource in the time domain resources occupied by transmitting the SSB burst set. The third offset value also may be an offset value between the target time domain resource and any time domain resource in the time domain resources occupied by transmitting the SSB burst set.

The target time domain resource may be a starting time domain resource in the time domain resources occupied by transmitting the first PEI. The target time domain resource may also be a last time domain resource in the time domain resources occupied by transmitting the first PEI. The target time domain resource may also be any time domain resource in the time domain resources occupied by transmitting the first PEI.

In the embodiments of the present disclosure, a size of the time domain resources occupied by transmitting the first PEI may be a fixed value. That is, the size of the first time domain resource is may be a fixed value. In some implementations, the above fixed value may be predefined by protocol. In other implementations, the above fixed value may also configured by the network device.

Of course, the size of the first time domain resource may also be variable. At this time, a position of the time domain resource occupied by transmitting the PEI in the transmission cycle may be determined by two offset values. That is, an offset value between the starting time domain resource of the first time domain resource and the time domain resource occupied by the transmitting the SSB burst set is indicated by the offset value 1, and an offset value between the last time domain resource in the first time domain resource and the time domain resource occupied by transmitting the SSB burst set is indicated by the offset value 2. A time domain resource occupied by transmitting the SSB burst set may be a starting time domain resource occupied by transmitting the SSB burst set. A time domain resource occupied by transmitting the SSB burst set may be a last time domain resource occupied by transmitting the SSB burst set. A time domain resource occupied by transmitting the SSB burst set may be any time domain resource occupied by transmitting the SSB burst set.

The above third offset value may be specified by the network device or may be predefined by protocol. Embodiments of the present disclosure are not limited thereto. In addition, the time domain unit of the third offset value may be any time domain transmission unit, for example, a subframe, a time domain symbol, a slot, etc.

A transmission manner of PEI according to the embodiments of the present disclosure is described below with reference to FIG. 13 to FIG. 15. It should be noted that the third offset value in the schemes of FIG. 13 to FIG. 15 is an offset value between the starting time domain resource of the time domain resources occupied by transmitting the PEI and a last time domain resource of the time domain resources occupied by transmitting the SSB burst set.

Referring to FIG. 13, it is assumed that there are 4 transmission cycles of SSB burst sets, namely transmission cycle 1, transmission cycle 2, transmission cycle 3 and transmission cycle 4. The third offset value is PEI-offset3. The transmission density for the PEI N is 3, that is, PEI is transmitted once every 3 transmission cycles of SSB burst sets. In addition, an identity of the first SSB burst set associated with the first PEI is SSB burst 1.

Then, the time domain resources for transmitting PEI are located in transmission cycle 1 and transmission cycle 4, respectively. In transmission cycle 1, the offset value between the starting time domain resource of the time domain resources occupied by transmitting the PEI and the last time domain resource of the time domain resources occupied by transmitting the SSB burst set is PEI-offset 3. In transmission cycle 4, the offset value between the starting time domain resource of the time domain resources occupied by transmitting the PEI and the last time domain resource of the time domain resources occupied by transmitting the SSB burst set is PEI-offset 3.

Referring to FIG. 14, it is assumed that there are 4 transmission cycles of SSB burst sets, namely transmission cycle 1, transmission cycle 2, transmission cycle 3 and transmission cycle 4. The third offset value is PEI-offset3. The transmission density for the PEI N is 2, that is, PEI is transmitted once every 2 transmission cycles of SSB burst set. In addition, an identity of the first SSB burst set associated with the first PEI is SSB burst 1.

Then, the time domain resources for transmitting PEI are located in transmission cycle 1 and transmission cycle 3, respectively. In transmission cycle 1, the offset value between the starting time domain resource of the time domain resources occupied by transmitting the PEI and the last time domain resource of the time domain resources occupied by transmitting the SSB burst set is PEI-offset 3. In transmission cycle 3, the offset value between the starting time domain resource of the time domain resources occupied by transmitting the PEI and the last time domain resource of the time domain resources occupied by transmitting the SSB burst set is PEI-offset 3.

Referring to FIG. 15, it is assumed that there are 4 transmission cycles of SSB burst sets, namely transmission cycle 1, transmission cycle 2, transmission cycle 3 and transmission cycle 4. The third offset value is PEI-offset3. The transmission density for the PEI N is 1, that is, PEI is transmitted once every 1 transmission cycle of SSB burst set. In addition, an identity of the first SSB burst set associated with the first PEI is SSB burst 1.

Then, the time domain resources for transmitting PEI are respectively located in transmission cycle 1, transmission cycle 2, transmission cycle 3 and transmission cycle 4, and in each transmission cycle, the offset value between the starting time domain resource of the time domain resources occupied by transmitting the PEI and the last time domain resource of the time domain resources occupied by transmitting the SSB burst set is PEI-offset 3.

As mentioned above, an index of the SSB burst set associated with the PEI needs to be determined first when determining a position within the time domain resources occupied by transmitting the PEI. The embodiments of the present disclosure also provides a manner for determining an index of the SSB burst set associated with the PEI. That is, a Y-th SSB burst set of each X SSB burst sets may be determined to be an SSB burst set associated with the PEI by the formula mod (M, X)=Y, where X and Y represent positive integers.

It should be noted that the values of X and Y may be configured by the network or fixed values predefined by protocol.

A method for transmitting PEIs periodically according to an embodiment of the present disclosure has been described above in connection with FIG. 11-FIG. 15, of course, the PEI may also be transmitted according to a transmission pattern, where the transmission pattern is used to indicate a length of time between each two transmissions of the PEI. Embodiments of the present disclosure do not specifically limit the transmission manner of PEIs.

In another example of the present disclosure, the time domain resources occupied by transmitting the PEI may also be determined directly based on an association relationship between a PEI and an index of the SSB burst set. That is, the operation that the terminal determines the first time domain resource occupied by transmitting the first PEI includes that: the terminal determines an index of a first SSB burst set associated with the first PEI based on an association relationship between a PEI and an index of a SSB burst set; and the terminal determines the first time domain resource based on time domain resources for transmitting the first SSB burst set and a positional relationship between time domain resources occupied by transmitting the SSB burst sets and time domain resources occupied by transmitting the PEIs.

The association relationship between the PEI and the index of SSB burst set may be expressed by a formula. For example, a Y-th SSB burst set of each X SSB burst sets is determined to be the SSB burst set associated with the PEI by the formula mod (M, X)=Y, where X and Y represent positive integers. The association relationship between the PEI and the index of the SSB burst set may also be represented by an index pattern of the SSB burst set. For example, the SSB burst set index is denoted as {SSB1, SSB2, SSB3, SSB4, SSB5, SSB6}, and the index pattern of the SSB burst set is denoted as {1, 0, 0, 0, 1, 0}, where 1 denotes the SSB burst set index is associated with the PEI at a position corresponding to a pattern, and 0 denotes that the SSB burst set index at a position corresponding to a pattern does not need to be associated with PEI. Then, based on the index pattern of the SSB burst set, SSB burst set indexes SSB1 and SSB5 are associated with the PEI.
