This application is based upon and claims priority to Chinese Patent Application No. 202110871006.6, filed with the State Intellectual Property Office of P. R. China on Jul. 30, 2021, the entire contents of which are incorporated herein by reference.
The disclosure relates to a field of wireless technologies, and more particularly to a method and an apparatus for detecting a signal or channel, a terminal, and a storage medium.
In the related art, it is indicated by a paging early indication (PEI) whether a terminal needs to detect a paging physical downlink control channel (PDCCH) and a corresponding physical downlink shared channel (PDSCH). However, the terminal in an idle state or inactive state may not receive terminal-specific configuration information, and the terminal may merely determine a terminal-specific PEI detection parameter based on broadcast configuration information on a network side.
For solving the problem in the related art, embodiments of the disclosure provide a method and an apparatus for detecting a signal or channel, a terminal, and a storage medium.
The technical solution of embodiments of the disclosure is implemented as follows.
Embodiments of the disclosure provide a method for detecting a signal or channel, applied to a first terminal, including:
determining a first detection parameter for a first signal or a first channel of the first terminal based on a paging configuration parameter of the first terminal.
The first signal or the first channel is configured to indicate whether the terminal detects a paging.
Embodiments of the disclosure also provide an apparatus for detecting a signal or channel, including:
a determining unit, configured to determine a first detection parameter for a first signal or a first channel of the first terminal based on a paging configuration parameter of the first terminal.
The first signal or the first channel is configured to indicate whether the terminal detects a paging.
Embodiments of the disclosure also provide a first terminal, including: a first processor, and a first communication interface.
The first processor is configured to determine a first detection parameter for a first signal or a first channel of the first terminal based on a paging configuration parameter of the first terminal.
The first signal or the first channel is configured to indicate whether the terminal detects a paging.
Embodiments of the disclosure also provide a first terminal, including: a first processor, and a first memory, configured to store a computer program executable on the processor.
The first processor is configured to perform steps in any of the above methods when executing the computer program.
Embodiments of the disclosure also provide a storage medium having a computer program stored thereon. The computer program is executed by a processor to implement steps in any of the above methods.
With the method and the apparatus for detecting a signal or channel, the terminal, and the storage medium provided by embodiments of the disclosure, the first terminal determines, based on the paging configuration parameter of the first terminal, the first detection parameter for the first signal or the first channel indicating whether the terminal detects the paging. In the above solution, the terminal determines the first detection parameter for the first signal or the first channel based on the paging configuration parameter of the terminal itself, instead of determining the first detection parameter for the first signal or the first channel based on terminal-specific configuration information sent by the network side. In this way, the configuration of the first detection parameter for the first signal or the first channel may not bring additional signaling overhead. Moreover, the terminal may determine the first detection parameter for the first signal or the first channel when it is in the idle state or the inactive state, so as to detect the first signal or the first channel, thereby saving energy of the terminal.
In the new radio (NR), a terminal detects a paging message in a discontinuous reception (DRX) way. The terminal detects one paging opportunity (PO) in each DRX period, in which one PO refers to a group of PDCCH detection opportunities, including multiple time slots. In a practical application, the PDCCH (hereinafter referred to as paging PDCCH) indicating the paging message transmitted on the PO may be scrambled by a paging radio-network temporary identifier (P-RNTI). A paging frame (PF) may include one or more POs. The PF satisfies a formula of (SFN+PF_offset) mod T=(T div N)*(UE_ID mod N). In addition, the terminal queries PO through an index i_s: i_s=floor (UE_IDIN) mod Ns. SFN represents a system frame number, PF_offset represents an offset value for calculating the PF, T represents a DRX period of the terminal, N represents the number of PFs included in the period T, and Ns represents the number of POs included in one PF, and UE_ID is equal to 5G-S-TMSI mod 1024. Here, S-TMSI is a system architecture evolution (SAE) temporary mobile station identifier, and 5G-S-TMSI is a bit string with 48 bits defined in TS 23.501. When the terminal does not have the 5G-S-TMSI, UE_ID is equal to 0. In the above formula, N and Ns are configured by a radio resource control (RRC).
Based on such NR paging design, terminals with a same or different UE_IDs may calculate a same PO position. Therefore, the terminal needs to further read the PagingRecordList in a physical downlink shared channel (PDCCH) scheduled by the paging PDCCH after detecting the paging PDCCH, and to determine whether the PagingUE-Identity in the PagingRecordList matches the 5G-S-TMSI or full I-RNTI of the terminal. In this way, it is determined whether the terminal is paged. In other words, the terminal also needs to detect the PDCCH scheduled by the PDCCH transmitted on the PO, to determine whether there is really a paging message. In a practical application, even if only one of terminals corresponding to one PO needs to be paged, all the terminals corresponding to the PO need to detect the paging PDSCH and the corresponding PDSCH. Such detection actions are meaningless to a terminal that does not need to be paged, which may cause a terminal in an idle state or an inactive state to spend too much energy on an invalid detection behavior.
In order to avoid the above problems, a paging early indication (PEI) is configured to indicate whether the terminal needs to detect the paging PDCCH and the corresponding PDCCH in the related art. Presently, the NR may configure multiple paging parameters N and Ns. In a scene of a high paging density, for example, in a maximum density (ontT, NS=4), there may be one PO every 2.5 ms. When there is a one-to-one mapping relationship between the PEI and the PO, an overhead of the PEI may increase due to the high paging density. Considering that all of the PEI, the paging PDC and the corresponding PDCCH, as well as a synchronization signal block (SSB), a system message and the like are transmitted in an initial downlink band width part (BWP), such high paging density may cause a resource shortage of the initial downlink BWP. Therefore, in the scene of the high paging density, it is designed that one PEI may correspond to multiple POs, that is, one PEI indicates whether multiple POs are woken up. In a scene of a low paging density, the PEI may not generate too much overhead. In order to further improve an energy-saving gain of a paging detection of the terminal, terminals corresponding to one PO may be grouped, and one PEI may indicate whether multiple terminal groups are woken up. In this way, since the number of terminals in the terminal group is less than the number of terminals in one PO, a probability that the terminal is woken up may be further reduced, and the energy-saving gain may be improved.
Therefore, from a network side, there is a mapping relationship between the PEI and the PO, and a mapping relationship between the PEI and the terminal group. From the terminal side, one terminal may merely correspond to one PEI, but the PEI is shared with other terminals. Since the terminal in the idle state or the inactive state may merely receive public broadcast configuration information, but may not receive terminal-specific configuration information, the design of the PEI needs to consider how to enable the terminal in the idle state or the inactive state to determine the corresponding PEI. For example, when the PEI is a kind of PDCCH, how does the terminal know a position of a bit corresponding to the terminal itself in the downlink control information (DCI) format? When the PEI is a reference signal, how does the terminal know a sequence parameter corresponding to the terminal itself, such as an index of a sequence or an index of a cyclic shift?
The base station may not perform configuration for a terminal by utilizing a dedicated configuration. Meanwhile, in consideration of different mapping relationships of the N, the Ns, the PEI with the PO and the number of terminal groups, there is a need to design an implicit method for determining and detecting the PEI, such that different terminals may determine their own PEI detection parameters merely relying on public configuration parameters in a system information block (SIB).
Based on this, in embodiments of the application, based on a paging configuration parameter of a first terminal, the first terminal determines a first detection parameter for a first signal or a first channel indicating whether the terminal detects a paging. In the above solution, the terminal determines the first detection parameter for the first signal or the first channel based on the paging configuration parameter of the terminal itself, instead of determining the first detection parameter for the first signal or the first channel based on the terminal-specific configuration information sent by the network side. In this way, a configuration of the first detection parameter for the first signal or the first channel may not bring an additional signaling overhead, and the terminal may determine the first detection parameter for the first signal or the first channel when it is in the idle state or the inactive state, to perform detection on the first signal or the first channel, thereby saving energy of the terminal.
Detailed description will be further made below to the disclosure with reference accompanying drawings and embodiments.
Embodiments of the disclosure provide a method for detecting a signal or a channel, applied to a first terminal. As illustrated in
At block 101, a first detection parameter for a first signal or a first channel of the first terminal is determined based on a paging configuration parameter of the first terminal,
The first signal or the first channel is configured to indicate whether the first terminal detects a paging.
In a practical application, the first signal or the first channel may be understood as a PEI, or another physical signal or physical channel configured to indicate whether the terminal detects the paging. The first detection parameter is a parameter configured to detect the PEI.
In an embodiment, the first detection parameter includes at least one of:
a bit position;
a sequence cyclic shift;
a sequence index; or
a detection position.
Here, a parameter for instructing the first terminal to detect the first signal or the first channel may be determined based on the paging configuration parameter of the first terminal. In case that the first signal or the first channel is a PDCCH, the first detection parameter indicates the bit position where the first terminal detects paging indication information corresponding to the first terminal itself on the PDCCH. In case that the first signal or the first channel is a sequence, the first detection parameter indicates the sequence cyclic shift or the sequence index of a sequence corresponding to the first terminal. In case that the first signal or the first channel is multiple PDCCHs or sequences, and that one PDCCH or sequence corresponds to one PO or one terminal group, the first detection parameter indicates the corresponding detection position where the first terminal detects a corresponding PDCCH or sequence.
In an embodiment, the first detection parameter represents a parameter determined at least based on a first index of the first terminal, and the first index represents an index of a paging opportunity (PO) of the terminal.
As mentioned above, the terminal queries the PO through the index i_s. Here, the first detection parameter may represent a parameter determined at least based on the index i_s of the first terminal.
In a practical application, there is a scene where a sending period of the first signal or one first channel is the same as a sending period or a time interval of the PF, in which:
1. In case that one first signal or one first channel corresponds to one or more POs, that is, one first signal or one first channel is configured to indicate whether one or more terminals of one PO or more POs need to detect the paging, the first detection parameter of the first terminal represents the first index.
In this case, a correspondence between the index i_s and the parameter configured to detect the first signal or the first channel is predefined. In case that the first signal or the first channel is one PDCCH, i_s=0 corresponds to the first bit, and i_s=1 corresponds to the second bit, when the index of the first terminal is i_s=0, the first detection parameter indicates that the first terminal detects the PDCCH. In case that the first signal or the first channel is a sequence, i_s=0 corresponds to a cyclic shift #1, and i_s=1 corresponds to a cyclic shift #2, when the index of the first terminal is i_s=0, the first detection parameter indicates that the first terminal detects a sequence of the cyclic shift #1. In case that the first signal or the first channel is multiple PDCCHs or sequences, one PDCCH or sequence corresponds to one PO, i_s=0 corresponds to a detection position #0 of the PDCCH or sequence, and i_s=1 corresponds to a detection position #1 of the PDCCH or sequence, when the index of the first terminal is i_s=0, the first detection parameter indicates that the first terminal detects a corresponding PDCCH or sequence on a detection position #0 of the PDCCH or the sequence.

2. In case that one first signal or first channel corresponds to one or more terminal groups on one or more POs, that is, one first signal or one first channel is configured to carry or indicate information whether one or more terminal groups detect the paging, the first detection parameter of the first terminal is determined based on a first index, a second index and a first number.
The second index represents an index of a corresponding terminal group to which the first terminal belongs. The first number represents the number of terminal groups. The first index represents an index of a paging opportunity (PO) of the terminal.
Taking the PEI as an example, here, one first signal or one first channel (PEI) is configured to carry or indicate the information whether the one or more terminal groups detect the paging. In this case, exemplarily, the first detection parameter may be determined based on i_s*M+m, where M represents the number of terminal groups in one PO, m represents the index of a corresponding terminal group to which the first terminal belongs, and i_s represents the index of the PO of the terminal. In detail, a correspondence between i_s*M+m and a parameter configured to detect the first signal or the first channel is predefined. In case that the first signal or the first channel is a PDCCH and that the index of the first terminal is i_s=0, the first terminal detects a bit determined by or corresponding to 0*M+m in the PDCCH. In case that the first signal or the first channel is a sequence and that the index of the first terminal is i_s=0, the first terminal detects a sequence determined by or corresponding to a cyclic shift or a sequence index which is 0*M+m. In case that the first signal or the first channel is multiple PDCCHs or sequences, and that the index of the first terminal is i_s=0, the first terminal detects a PDCCH or a sequence on a detection position of the PDCCH or the sequence determined by or corresponding to 0*m+m.
In combination with the detailed example of
In combination with the detailed example of
In a practical application, there is also a scene where the sending period of the first signal or the first channel is different from the sending period of the PF, in which:
1. In case that one first signal or one first channel corresponds to one or more POs, that is, one first signal or one first channel is configured to indicate whether one or more terminals of the one PO or more POs need to detect the paging, the first detection parameter of the first terminal is determined based on the first index and a first numerical value.
The first numerical value represents a value determined by a system frame number of a paging frame (PF), a first time length and a second time length. The first time length represents a time interval between adjacent first signals or adjacent first channels, and the second time length represents a time interval between adjacent PFs.
In an embodiment, the first numerical value represents a modulus of a first ratio to a second ratio. The first ratio represents a ratio of the system frame number of the PF to the second time length, and the second ratio represents a ratio of the first time length to the second time length.
Taking the PEI as an example, there is a one-to-one mapping relationship between the first signal or the first channel and the PO, and one first signal or one first channel corresponds to one PO. In this case, exemplarily, the first detection parameter may be determined based on (SFN/T1 mod K)*Ns+i_s, where SFN represents the system frame number of the PF, T1 represents the second time length, that is, the time interval between two adjacent PFs, which may also be understood as the sending period of the PF, and K represents the ratio of the first time length to the second time length. The first time length represents the time interval between the adjacent first signals or the adjacent first channels, which may also be understood as the sending period of the first signal or the first channel. In detail, a correspondence between (SFN/T1 mod K)*Ns+0 and a parameter configured to detect the first signal or the first channel is predefined. In case that the first signal or the first channel is a PDCCH, and that the index of the first terminal is i_s=0, the first terminal detects a bit corresponding to (SFN/T1 mod K)*Ns+0 in the PDCCH. In case that the first signal or the first channel is a sequence, and that the index of the first terminal is i_s=0, the first terminal detects a sequence corresponding to a cyclic shift which is (SFN/T1 mod K)*Ns+0. In case that the first signal or the first channel is multiple PDCCHs or sequences, and that the index of the first terminal is i_s=0, the first terminal detects a corresponding PDCCH or sequence on a detection position of the PDCCH or the sequence corresponding to (SFN/T1 mod K)*Ns+0.

In combination with a detailed example of
The first numerical value represents the value determined by the system frame number of the paging frame (PF), the first time length and the second time length. The second index represents an index of a corresponding terminal group to which the first terminal belongs. The first number represents the number of terminal groups, the first time length represents the sending period of the signal or channel, or the time interval between adjacent signals or adjacent channels, and the second time length represents the time interval between adjacent PFs.
In an embodiment, the first numerical value represents the modulus of the first ratio to the second ratio. The first ratio represents the ratio of the system frame number of the PF to the second time length, and the second ratio represents the ratio of the first time length to the second time length.
In an embodiment, the method also includes:
receiving the second ratio or the first time length configured through a system message by a network side
Taking the PEI as an example. Here, one first signal or one first channel (PEI) is configured to carry or indicate the information whether one or more terminal groups detect the paging. In this case, exemplarily, the first detection parameter may be determined based on [(SFN/T1 mod K)*Ns+i_s]*M+m, where SFN represents the system frame number of the PF; T1 represents the second time length, that is, the time interval between two adjacent PFs, which may also be understood as the sending period of the PF; K represents the ratio of the first time length to the second time length, in which, the first time length represents the time interval between the adjacent first signals or the adjacent first channels, which may also be understood as the sending period of the first signal or the first channel; M represents the number of terminal groups in one PO; and m represents the index of a corresponding terminal group to which the first terminal belongs. In detail, a correspondence between [(SFN/T1 mod K)*Ns+i_s]*M+m and a parameter configured to detect the first signal or the first channel is predefined. In case that the first signal or the first channel is one PDCCH and that the index of the first terminal is i_s=0, the first terminal detects the PDCCH at a bit corresponding to [(SFN/T1MODK)*ns+0]. In case that the first signal or the first channel is a sequence and that the index of the first terminal is i_s=0, the first terminal detects a sequence of a cyclic shift corresponding to [(SFN/T1 mod K)*Ns+0]*M+m. In case that the first signal or the first channel is multiple PDCCHs or sequences, that one PDCCH or sequence corresponds to one PO, and that the index of the first terminal is i_s=0, the first terminal detects a PDCCH or a sequence at a detection position of the PDCCH or the sequence corresponding to [(SFN/T1 mod K)*Ns+0]*M+m.
