The present application relates to the field of communication technologies and, in particular, to a signal processing method and a signal processing apparatus.
In a new radio (NR) release (release 16, R16), each paging occasion (PO) contains monitoring occasions (MOs).
In a possible manner, in a case where a position of a starting MO is not configured by a PO parameter, a base station starts from configuring a first valid MO of a paging frame (PF) as a first PO, and performs sequential numbering. In a case where the position of the starting MO is configured by the PO parameter, when POs are configured as continuous or discontinuous, the base station starts from configuring a first MO of a PF as a first PO, and performs sequential numbering.
However, no matter whether a parameter of an MO of a first PDCCH of a PO is configured or not, a case where different POs are configured within one slot may occur, and further, a conflict problem caused by paging occasion indications within one slot may occur.
Embodiments of the present application provide a signal processing method and a signal processing apparatus. A network device configures a paging early indication for a terminal device in an idle state, and after the network device sends the paging early indication to the terminal device, the terminal device can accurately indicate physical downlink control channel (PDCCH) monitoring at a paging occasion, which avoids unnecessary false wake-up or non-wake-up caused by a paging occasion conflict, thereby reducing power consumption of the terminal device.

In one embodiment of the present application provides a processor-readable storage medium, where the processor-readable storage medium stores a computer program, and the computer program is used for causing a processor to execute the method as described in the embodiments.
In one embodiment of the present application provides a computer program product including instructions, and when the instructions run on a computer, the computer is caused to execute the method in the above embodiments.
In one embodiment of the present application provides a signal processing system, including any of the above network device and any of the above terminal device.
To describe embodiments of the present application more clearly, the following briefly introduces accompanying drawings required for describing the embodiments or the prior art. Apparently, the accompanying drawings in the following description show some embodiments of the present application.
The term “and/or” in the present application describes an association relationship between associated objects, and represents that there may exist three relationships. For example, A and/or B may represent three cases: A exists separately, A and B exist simultaneously, and B exists separately. The character “/” generally indicates an “or” relationship between the associated objects before and after the character.
The term “a plurality of” in embodiments of the present application refers to two or more, and other quantifiers are similar thereto.
The following clearly and comprehensively describes the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present application.
The embodiments of the present application may be applicable to various systems, and in particular, to a 5G system. For example, an applicable system may be a global system of mobile communication (GSM), a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) system, a general packet radio service (GPRS) system, a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a long term evolution advanced (LTE-A) system, a universal mobile telecommunication system (UMTS), a worldwide interoperability for microwave access (WiMAX) system, a 5G new radio (NR) system, etc. The various systems all include a terminal device and a network device, and further include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.
In the new radio (NR) release (release 16, R16), based on the description of 38.304, each paging occasion (PO) contains monitoring occasions (MOs), and configuration for paging occasions can be understood as configuration for positions of different POs.
In a possible manner, a network device configures MOs of different POs as continuous counting; or the network device may separately configure starting positions for MOs of different POs, where an offset value of a starting position is configurable.
In a case where a position of a starting MO is not configured by a PO parameter, in a paging frame (PF), the network device starts from configuring a first valid MO of the PF as a first PO, and performs sequential numbering as PO2, PO3, and PO4.
Illustratively,
In a possible manner, an identifier of a PO position may be represented according to the quantity of synchronization signal blocks (SSBs). For example, a serial number of an n-th PO position may be a product of n and the quantity of SSBs corresponding to a PO, where n is a natural number.
In a case where the position of the starting MO is configured by the PO parameter, the POs being continuously configured on continuous orthogonal frequency division multiplexing (OFDM) symbols may occur in the PF, and an OFDM symbol slot may also exist between different POs due to partial parameter configuration.
Illustratively,
Illustratively,
In a possible case, a paging early indication (paging early indication, PEI) is configured in the PF to indicate monitoring of an MO of a physical downlink control channel (PDCCH) of a paging signal. In one embodiment, in the NR R16, downlink control information (DCI) format 2-6 may be used for indicating the monitoring of the MO of the PDCCH of the paging signal. DCI format 2-6 indicates monitoring of a PDCCH of a starting position of a DRX cycle after a configuration of a minimum distance being a minimum-gap, and a configuration unit of DCI format 2-6 is also a configuration of milliseconds (ms).
According to another embodiment, in long term evolution (LTE), a narrow band Internet of things (NB-IOT) uses a sequence-based wake-up signal (WUS) to indicate whether it is necessary to wake up to monitor paging within I-DRX. For example, the WUS can respectively indicate a cell identifier (cell-id), a starting sub-frame number of a PO and the number of repetitions of the same PO to determine whether it is necessary to monitor paging. It can be understood that a WUS indication of the NB-IoT may also be a sub-frame.
However, the PEI configured under the NR may have a problem that it cannot distinguish which PO within a slot. Illustratively,
Based on the above, the embodiments of the present application provide a signal processing method and a signal processing apparatus. A network device configures a paging early indication for a terminal device in an idle state; and after the network device sends the paging early indication to the terminal device, the terminal device can accurately indicate PDCCH monitoring at a paging occasion, to avoid unnecessary false wake-up or non-wake-up caused by a paging occasion conflict, and reducing power consumption of the terminal device.
The embodiments of the present application and how the embodiments of the present application solve the above problem will be described in detail below with reference to specific embodiments. The following specific embodiments may be implemented independently or combined with each other, and the same or similar concept or process may not be repeated in some embodiments.
S501: a network device configures a paging early indication.
In the embodiment of the present application, the paging early indication may be a DCI-based indication signal, and may also be a sequence-based indication signal. The paging early indication is used for indicating monitoring of a physical downlink control channel (PDCCH) of at least one paging occasion, and/or monitoring of at least one PDCCH with different paging contents.
For example, the paging early indication may be used for indicating one or more of the following: whether a paging signal exists at a paging occasion, or whether to monitor a PDCCH of the paging signal at the paging occasion, or whether to monitor the paging signal at the paging occasion; or that the paging signal exists at the paging occasion, or to monitor the PDCCH of the paging signal at the paging occasion, or to monitor the paging signal at the paging occasion.
It can be understood that, the paging early indication (PEI) is a manner used by the embodiments of the present application for the convenience of description, and the signal may also be referred to as other nouns. The embodiments of the present application focus on describing the role of the signal, and the name of the signal does not constitute a limitation to the signal itself. A specific implementation format for the network device to configure the paging early indication may also be based on an actual application scenario, which is not limited herein.
S502: the network device sends the paging early indication to the terminal device.
S503: the terminal device performs data processing according to the paging early indication.
The embodiment of the present application does not limit a specific sending manner for the network device to send the paging early indication to the terminal device.
After receiving the paging early indication, the terminal device may receive a paging signal at a corresponding position based on the indication of the paging early indication, to implement conversion from an idle state to a connected state and the like. The embodiment of the present application does not limit a specific embodiment for the terminal device to perform data processing according to the paging early indication.
In conclusion, after configuring the paging early indication, the network device sends the paging early indication to the terminal device, and the terminal device can perform data processing according to the paging early indication, to accurately indicate PDCCH monitoring at a paging occasion, avoiding unnecessary false wake-up or non-wake-up, and reducing power consumption of the terminal device.
It should be noted that,
S501: a network device configures a paging early indication.
In the embodiment of the present application, for a manner of configuring the paging early indication by the network device, reference may be made to the description of the foregoing embodiment, and details are not repeated here.
In one embodiment, one PEI may indicate paging PDCCH monitoring of paging occasions. Illustratively,
In one embodiment, the paging early indication may be used for indicating at least one of the following: an identifier of a paging frame within a paging cycle, an identifier of a monitoring occasion (MO) of a first paging PDCCH of a first paging occasion included in a paging frame, an identifier of a paging occasion group in a paging frame, a terminal identifier or a terminal group identifier of a paging occasion in a paging frame.
Illustratively, the identifier of the paging frame may include one or more of the following: a unique identifier of the paging frame within a paging cycle, a serial number of the paging frame within a paging cycle, or an identifier of a time-domain position where the paging frame is located within a paging cycle. For example, the unique identifier of the paging frame within the paging cycle may be a serial number of the paging frame.
Illustratively, the identifier of the monitoring occasion (MO) of the first paging PDCCH of the first paging occasion included in the paging frame may include a unique serial number of the monitoring occasion (MO) in the paging frame or an indication of a time-domain position where the monitoring occasion (MO) is located. The indication of the time-domain position may include one or more of the following: a time-domain position of a time-domain frame, a time-domain position of a sub-frame in a frame, a time-domain position of a slot in a sub-frame, or a time-domain position of a symbol in a slot.
Illustratively, the identifier of the paging occasion group in the paging frame may include a unique serial number of the paging occasion group in the paging frame, an identifier of a time-domain position of each paging occasion group, a unique serial number of a monitoring occasion (MO) of a first paging PDCCH in each paging group of the paging occasion group in the paging frame, or an identifier of a time-domain position of a first paging occasion of the paging occasion group, where the paging occasion group includes at least one paging occasion.
Illustratively, the terminal identifier or the terminal group identifier of the paging occasion in the paging frame may include a unique serial number of a terminal or a terminal group in the paging frame, a relative serial number of the terminal or the terminal group in the paging frame.
In one embodiment, one PEI may indicate paging PDCCH monitoring of one paging occasion. Illustratively,
In one embodiment, illustratively, the paging early indication may be used for indicating at least one of the following: an identifier indicating a paging occasion, an identifier indicating a paging frame and a paging occasion in the paging frame, a sequential number indicating a paging occasion within a paging cycle or an identifier indicating whether to monitor a PDCCH.
Illustratively, the identifier indicating the paging occasion may be a unique serial number in the paging occasion, or may include an identifier of a time-domain position in the paging occasion; and may be an identifier of a unique monitoring occasion (MO) for paging in the paging occasion. The identifier of the unique monitoring occasion (MO) for paging in the paging occasion may be a unique serial number of the monitoring occasion (MO), or may be an indication of a time-domain position of the monitoring occasion (MO), which is used for indicating a relationship between the paging early indication and the paging monitoring occasion (MO) of each paging occasion in the paging frame. The indication of the time-domain position may include at least one of the following: a time-domain position of a time-domain frame, a time-domain position of a sub-frame in a frame, a time-domain position of a slot in a sub-frame or a time-domain position of a symbol in a slot.
Illustratively, the sequential number indicating the paging occasion within the paging cycle may be that, within a DRX cycle, at most 64 POs may be configured by sequential numbers indicating paging occasions within the paging cycle; one PO corresponds to one serial number, and there are at most 64 PO serial numbers; and a PEI indicating a serial number of a PO uniquely distinguishes an identifier of the indicated PO.
Illustratively, the identifier indicating the paging occasion in the PF may include a unique serial number of the PF within a paging cycle or an identifier of a time-domain position of the PF within a paging cycle. The identifier of the paging occasion in the PF is similar to a PF identifier. For example, within a DRX cycle, the network device may configure four PFs, which are numbered as PF1, PF2, PF3, and PF4; each PF may be configured with two POs, which are numbered as PO1 and PO2; and the paging early indication indicates (a PF serial number, a PO serial number).
It should be noted that, the “serial number” may be a serial number specified in a protocol; the “unique serial number” is a noun relative to the “relative serial number”; the “unique serial number” may be used for indicating a one-to-one relationship, and the “relative serial number” does not have one-to-one restriction.
S502: the network device sends the paging early indication to the terminal device.
In conclusion, after configuring the paging early indication, the network device sends the paging early indication to the terminal device, to accurately indicate PDCCH monitoring at a paging occasion, and subsequently, the terminal device can perform data processing according to the paging early indication, to avoid unnecessary false wake-up or non-wake-up, and reducing power consumption of the terminal device.
In one embodiment, on the basis of the foregoing embodiments, the paging early indication may be designed as a DCI format. Illustratively,
S801: a network device configures a paging early indication as a design of DCI format.
DCI may include bits, and the plurality of bits may also be referred to as a bit field. Each bit may be used for carrying different indication contents of the PEI. For example, any of the above-described contents indicated by the PEI may be carried by using one or more bits in the DCI.
Illustratively,
Bits for identifying the information of the POs may include one or more bits. For example, as shown in
It should be noted that, the quantities of bits corresponding to different POs may be the same or different. For example, since the quantities of UE subgroups corresponding to the POs are different, the quantities of bits used for representing the UE subgroups are also different, where the quantity of bits corresponding to a PO may be the same as the quantity of the UE subgroups corresponding to the PO. For example, as shown in
In the embodiment of the present application, the bits in the DCI can use “0” or “1” to indicate different contents. For example, bit 0 identifies that it is unnecessary to monitor a paging PDCCH at a PO position; bit 1 identifies that it is necessary to monitor the paging PDCCH at the PO position. Or, bit 1 identifies that it is unnecessary to monitor the paging PDCCH at the PO position; bit 0 identifies that it is necessary to monitor the paging PDCCH at the PO position. This is not specifically limited in the embodiment of the present application.
In one embodiment, the DCI may also be a combination of bit fields as shown in

As shown in
Bits identifying the information of the MOs may include one or more bits. For example, as shown in
It should be noted that, the quantities of bits corresponding to different MOs may be the same or different. For example, since the quantities of UE subgroups corresponding to the MOs are different, the quantities of bits used for representing the UE subgroups are also different, where the quantity of bits corresponding to an MO may be the same as the quantity of the UE subgroups corresponding to the MO. For example, as shown in
In the embodiment of the present application, the bits in the DCI can use “0” or “1” to indicate different contents. For example, bit 0 identifies that it is unnecessary to monitor a paging PDCCH at an MO position; bit 1 identifies that it is necessary to monitor the paging PDCCH at the MO position. Or, bit 1 identifies that it is unnecessary to monitor the paging PDCCH at the MO position; bit 0 identifies that it is necessary to monitor the paging PDCCH at the MO position. This is not specifically limited in the embodiment of the present application.

A specific identifying manner may be set according to an actual application scenario, and is not limited here. M and N may be equal or may be unequal, and M and N may be natural numbers.

S1701: a network device configures a paging early indication as a design of sequence format.

S1702: the network device sends the paging early indication to the terminal device.
In conclusion, after the network device configures the paging early indication as the design of sequence format, the network device sends the paging early indication to the terminal device, and the terminal device can perform data processing according to the paging early indication, to accurately indicate PDCCH monitoring at a paging occasion, avoiding unnecessary false wake-up or non-wake-up, and reducing power consumption of the terminal device.
It should be noted that,
S1801: a terminal device receives a paging early indication from a network device.
In the embodiment of the present application, the terminal device is in an idle state, and the idle state is a state in which normal data transmission is not performed between the terminal device and the network device. For example, in the idle state, the terminal device only performs basic radio resource management measurement, synchronization, channel time-frequency tracking, paging message reception, a random access process or a beam management process of a radio link.
In the embodiment of the present application, the paging early indication is configured according to the network device, and for the configuration of the paging early indication by the network device, reference may be made to the adaptive description of contents of corresponding steps in the embodiments of the network device side, and the details are not described here again.
S1802: the terminal device performs data processing according to the paging early indication.
Illustratively, after receiving the paging early indication, the terminal device may determine, according to the paging early indication, whether to receive a paging signal. For example, if it is indicated that the paging signal needs to be received, the terminal device receives a paging PDCCH, and optionally a paging PDSCH, and performs corresponding demodulation and decoding. If it is indicated that no paging signal needs to be received, the terminal device does not receive the paging PDCCH and does not receive the paging PDSCH.
The paging signal may represent a signal which is sent at a paging occasion and used for paging a terminal. Parameter configuration of the paging signal includes at least one of the following: a cycle of the paging signal, for example, the cycle of the paging signal may be configured to be 32 radio frames, 64 radio frames, 128 radio frames, 256 radio frames, and other values, which are not limited; the quantity of paging frames in a paging cycle, which is configured by a signaling, and represents how many paging frames are configured within one paging cycle, where a unit of each paging frame is a radio frame, i.e. 10 ms; that a paging cycle includes at least one paging frame; the quantity of paging occasions in a paging frame, which is configured by RRC, and represents the configuration of the quantity of paging occasions in one paging frame; that a paging frame includes at least one paging occasion; a time-domain offset of a paging frame of each paging occasion; a time-domain offset of a paging occasion, etc. This is not specifically limited in the embodiment of the present application.
In conclusion, after configuring the paging early indication, the network device sends the paging early indication to the terminal device, and the terminal device can perform data processing according to the paging early indication, to accurately indicate PDCCH monitoring at a paging occasion, avoiding unnecessary false wake-up or non-wake-up, and reducing power consumption of the terminal device.
It can be seen from the above-described embodiments that, the paging early indication can indicate different POs. Further, a base station can solve the conflict problem caused by the presence of PEIs within one slot (slot) according to the manner of carrying the time-domain position of the paging occasion (for example, slot information or symbol information). After configuring the paging early indication, the network device sends the paging early indication to the terminal device, and the terminal device can perform data processing according to the paging early indication, to accurately indicate PDCCH monitoring at a paging occasion, avoiding unnecessary false wake-up or non-wake-up, and reducing power consumption of the terminal device.
