Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of communications, and in particular to a communication method and apparatus. BACKGROUND

[0002] In a communication system, packet data services are often bursty, and data transmission is occasionally active for a period of time and then remains silent for a longer period of time. From the perspective of delay, the terminal always monitors the physical downlink control channel (PDCCH) to receive uplink scheduling or downlink data, and the resulting delay is the smallest. However, constantly monitoring the PDCCH will result in huge power consumption.

[0003] In order to solve the contradiction between delay and power consumption, a wake-up signal (WUS) mechanism is introduced in new radio (NR) to reduce the power consumption of the terminal.

[0004] In order to further reduce the power consumption of the terminal, the terminal can monitor through a lower power wake up receiver (LP-WUR), and after monitoring a lower power wake up signal (LP-WUS), the main receiver can be awakened, so that the main receiver can perform data transmission and reception during the wake-up period. However, if the terminal does not have data transmission and reception services during the wake-up period, the terminal is in an invalid wake-up state, and being in the invalid wake-up state will increase the power consumption of the terminal. SUMMARY

[0005] Embodiments of the present application provide a communication method and apparatus, which can solve the problem of high false wake-up rate, save transmission resources, and further reduce the power consumption of the terminal.

[0006] To achieve the above object, embodiments of the present application adopt the following technical solutions:

[0007] In a first aspect, a communication method is provided. The method can be performed by a first terminal, or by a component of the first terminal, such as a processor, a chip, or a chip system of the first terminal, or by a logic module or software that can implement all or part of the function of the first terminal. The method includes: listening, by the first terminal, to a low-power wake-up signal through a low-power wake-up receiver; wherein the low-power wake-up signal carries first wake-up information and second wake-up information; the first wake-up information is used to indicate a terminal group that needs to be woken up; and the second wake-up information is used to indicate a terminal sub-group in the terminal group that needs to be woken up; the terminal sub-group includes one or more terminals that need to be woken up; and in a case where the first terminal is determined to be included in the terminal group that needs to be woken up according to the low-power wake-up signal, waking up a main receiver.

[0008] Based on this scheme, the low-power wake-up signal includes the first wake-up information and the second wake-up information. That is, the low-power wake-up signal includes two parts of wake-up information, one part is used to indicate a terminal group that needs to be woken up, and the other part is used to indicate a terminal in the terminal group that needs to be woken up, that is, the two parts of wake-up information can indicate a specific terminal that needs to be woken up, thereby solving the problem of high false wake-up rate, avoiding the first terminal being in an invalid wake-up state, and further reducing the power consumption of the first terminal.

[0009] In a possible design, the low-power wake-up signal includes a first wake-up signal, and the first wake-up signal includes the first wake-up information and the second wake-up information. That is, the first wake-up information and the second wake-up information are carried in the same wake-up signal, thereby saving transmission resources.

[0010] In a possible design, the low-power wake-up signal includes a second wake-up signal and a third wake-up signal, the second wake-up signal includes the first wake-up information, and the third wake-up signal includes the second wake-up information. That is, the first wake-up information and the second wake-up information are carried in different wake-up signals, thereby improving the accuracy of indicating a terminal that needs to be woken up.

[0011] In a possible design, determining, according to the low-power wake-up signal, that the first terminal is included in the terminal group that needs to be woken up includes: the group number of the terminal group that needs to be woken up indicated by the first wake-up information is the same as the group number of the terminal group where the first terminal is located; and / or, the sub-group number of the terminal sub-group in the terminal group that needs to be woken up indicated by the second wake-up information is the same as the sub-group number of the terminal sub-group where the first terminal is located.

[0012] Based on this possible design, the wake-up efficiency can be improved through group number matching and / or sub-group number matching.

[0013] In a possible design, the first wake-up information bit is a group number of the terminal group; the second wake-up information includes a bitmap; the bitmap includes at least one bit, and one bit corresponds to one terminal subgroup in the terminal group, and a value of the bit is used to indicate whether the terminal subgroup corresponding to the bit needs to be woken up.

[0014] Based on the possible design, the value of the number of bits occupied by the first wake-up information indicates the terminal group that needs to be woken up, and the bitmap included in the second wake-up information indicates the terminal subgroup in the terminal group that needs to be woken up, so that the network device can indicate the specific terminal that needs to be woken up, and the wake-up efficiency is improved.

[0015] In a possible design, the number of bits occupied by the first wake-up information is specified by a protocol or configured by the network device, and the number of bits occupied by the second wake-up information is specified by the protocol or configured by the network device; or the number of bits occupied by the first wake-up information is specified by the protocol or configured by the network device, and the number of bits occupied by the second wake-up information is obtained according to the number of bits occupied by the first wake-up information; or the number of bits occupied by the second wake-up information is specified by the protocol or configured by the network device, and the number of bits occupied by the first wake-up information is obtained according to the number of bits occupied by the second wake-up information.

[0016] In a possible design, in the case where the number of bits occupied by the first wake-up information and the number of bits occupied by the second wake-up information are configured by the network device, the method further includes: receiving first signaling from the network device, where the first signaling indicates the number of bits occupied by the first wake-up information and the number of bits occupied by the second wake-up information; and the first signaling is a system information broadcast (SIB), a radio resource control (RRC) signaling, a medium access control-control element (MAC-CE), or a downlink control information (DCI) signaling.

[0017] Based on the possible design, the network device can pre-configure the number of bits occupied by the first wake-up information and the number of bits occupied by the second wake-up information to the first terminal, and the first terminal can parse the wake-up signal according to the pre-configured number of bits occupied by the first wake-up information and the number of bits occupied by the second wake-up information to obtain the wake-up information, so that the receiving efficiency can be improved.

[0018] In a possible design, the first signaling further indicates that the first wake-up information is carried in the low-power wake-up signal in a first format, the first format includes the number of bits occupied by the first wake-up information, and a value of the number of bits occupied by the first wake-up information is a group number of the terminal group; and the first signaling further indicates that the second wake-up information is carried in the low-power wake-up signal in a second format, the second format includes a bitmap of the second wake-up information, and the bitmap indicates a subgroup number and a correspondence between the bitmap and the subgroup number.

[0019] Based on the possible design, the network device can also pre-configure the format of the first wake-up information and the second wake-up information to the first terminal, and the first terminal can parse the wake-up signal according to the pre-configured format of the first wake-up information and the second wake-up information to obtain the wake-up information, thereby improving the reception efficiency.

[0020] In a possible design, the method further includes: receiving second signaling from the network device, the second signaling including a group number of a terminal group to which the first terminal belongs, and a subgroup number of a terminal subgroup to which the first terminal belongs; the second signaling is RRC signaling; and further, the first terminal can save the group number of the terminal group to which the first terminal belongs, and the subgroup number of the terminal subgroup to which the first terminal belongs.

[0021] Based on the possible design, the network device can send the group number of the terminal group to which the first terminal belongs, and the subgroup number of the terminal subgroup to which the first terminal belongs to the first terminal, and after the first terminal saves the group number of the terminal group to which the first terminal belongs, and the subgroup number of the terminal subgroup to which the first terminal belongs, in the case that the first terminal monitors the low-power wake-up signal, the first terminal can determine whether the terminal subgroup that needs to be woken up in the terminal group includes the first terminal based on the saved group number and subgroup number, thereby improving the wake-up efficiency.

[0022] In a possible design, the method further includes: receiving third signaling from the network device; the third signaling indicates that the wake-up information of the wake-up signal uses a first information format in a plurality of information formats; the plurality of information formats include: indicating one or more terminals that need to be woken up by using a bitmap, indicating one or more terminals that need to be woken up by using an encoded format, indicating part of terminals that need to be woken up in a plurality of terminals having a same terminal identifier by using an encoded format, indicating one or more terminal groups that need to be woken up by using an encoded format, indicating one or more terminals that need to be woken up by using a bit block, indicating a terminal group that needs to be woken up by using an encoded format, and indicating a terminal subgroup that needs to be woken up in the terminal group by using a bitmap; and the first information format is indicating a terminal subgroup that needs to be woken up in the terminal group by using a bitmap.

[0023] Based on the possible design, the network device can pre-configure the information format used by the wake-up information of the wake-up signal to the first terminal, and the first terminal can parse the wake-up signal according to the configured information format, thereby improving the reception efficiency.

[0024] Secondly, a communication method is provided.

[0025] Based on this scheme, on the one hand, the network device divides multiple terminals associated with the CDRX cycle into the same terminal group. In this case, the network device can send a wake-up signal to multiple terminals in a terminal group on the same time domain resource, thereby avoiding wasting transmission resources.

[0026] Furthermore, on the other hand, the wake-up signal sent by the network device carries first wake-up information and second wake-up information. The first wake-up information indicates the terminal group that needs to be woken up, and the second wake-up information indicates the terminal in the terminal group that needs to be woken up. In other words, the network device can indicate the specific terminal in the terminal group that needs to be woken up, thereby solving the problem of false wake-up and reducing the false wake-up rate.

[0030] In a possible design, in the case where the number of bits occupied by the first wake-up information and the second wake-up information is configured by the network device, the method further includes: sending, to the first terminal, first signaling, where the first signaling indicates the number of bits occupied by the first wake-up information and the number of bits occupied by the second wake-up information; and the first signaling is system information broadcast (SIB), radio resource control (RRC) signaling, medium access control-control element (MAC-CE), or downlink control information (DCI) signaling.

[0031] In a possible design, the first signaling further indicates that the first wake-up information is carried in the low-power wake-up signal in a first format, the first format includes the number of bits occupied by the first wake-up information, and the number of bits occupied by the first wake-up information is a group number of a terminal group; and the first signaling further indicates that the second wake-up information is carried in the low-power wake-up signal in a second format, the second wake-up information of the second format includes a bitmap, and the bitmap indicates a sub-group number and a correspondence between the bitmap and the sub-group number.

[0033] In a possible design, the method further includes: sending, to the first terminal, third signaling; the third signaling indicates that the wake-up information of the wake-up signal uses a first information format in a plurality of information formats; the plurality of information formats include: a format for indicating one or more terminals that need to be woken up by using a bitmap, a format for indicating one or more terminals that need to be woken up by using encoding, a format for indicating part of terminals that need to be woken up in a plurality of terminals with a same terminal identifier by using encoding, a format for indicating one or more terminal groups that need to be woken up by using encoding, a format for indicating one or more terminals that need to be woken up by using a bit block, a format for indicating a terminal group that needs to be woken up by using encoding, and a format for indicating a terminal sub-group that needs to be woken up in the terminal group by using a bitmap; and the first information format is a format for indicating a terminal sub-group that needs to be woken up in a terminal group by using a bitmap.

[0075] The technical solutions provided in this application can be used in various communication systems, including 3GPP (3rd Generation Partnership Project) communication systems, such as 4G (4th Generation) Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, 5G (5th Generation) New Radio (NR) systems, vehicle-to-everything (V2X) systems, LTE and NR hybrid networking systems, device-to-device (D2D) systems, machine-to-machine (M2M) communication systems, Internet of Things (IoT) systems, and other next-generation communication systems. Alternatively, the communication system can also be a non-3GPP communication system, without limitation.

[0076] The communication systems described above that are applicable to the embodiments of this application are merely illustrative examples, and the communication systems applicable to the embodiments of this application are not limited thereto. They will be uniformly described here and will not be repeated below.

[0077] like Figure 1 The diagram shown is a schematic representation of a possible communication system provided in an embodiment of this application.Figure 1 In the communication system, at least one network device 110 and one or more terminals 120 are connected to the network device 110. It should be understood that, Figure 1 The number of terminals and network devices in the communication system is only an example, and there can be more or less.

[0078] Optionally, the network device 110 in the embodiment of the application is a device for connecting the terminal 120 to a wireless network. The network device 110 can be a node in a wireless access network, also known as a base station, and can also be referred to as a radio access network (RAN) node (or device).

[0079] For example, the network device can include an evolved NodeB (NodeB or eNB or e-NodeB, evolutional Node B) in an LTE system or an LTE-A system, such as a conventional macro base station eNB and a micro base station eNB in a heterogeneous network scenario. Alternatively, it can include a next generation NodeB (gNB) in an NR system. Alternatively, it can include a transmission reception point (TRP), a home base station (for example, a home evolved NodeB, or a home NodeB, HNB), a baseband unit (BBU), a baseband pool (BBU pool), or a wireless fidelity (WiFi) access point (AP), etc. Alternatively, it can include a base station in an NTN, which can be deployed on a high-altitude platform or a satellite. In an NTN, the network device can act as a layer 1 (L1) relay, or as a base station, or as a DU, or as an integrated access and backhaul (IAB) node. Alternatively, the network device can be a device that implements the base station function in IoT, such as V2X, D2D, or machine to machine (M2M), and the embodiments of the application are not limited.

[0080] Optionally, the base station in the embodiment of the application can include various forms of base stations, such as macro base stations, micro base stations (also known as small stations), relay stations, access points, home base stations, TRPs, transmitting points (TPs), mobile switching centers, etc., and the embodiments of the application are not limited.

[0081] Optionally, as one possible deployment form, as shown inFigure 2a As shown, the network device can include a central unit (CU) and / or a distributed unit (DU). Further, the network device can also include an active antenna unit (AAU) (not shown in FIG. 1). Figure 2a

[0082] Optionally, the CU can implement part of the functions of the network device, and the DU implements another part of the functions of the network device. For example, the CU can be responsible for processing non-real-time protocols and services, implementing the functions of the radio resource control (RRC) layer and the packet data convergence protocol (PDCP) layer. The DU can be responsible for processing the physical layer protocol and real-time services, implementing the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer. It should be noted that this division of protocol layers is only an example, and other protocol layer divisions are also possible.

[0083] Optionally, the AAU can implement part of the physical layer processing functions, radio frequency processing, and related functions of the active antenna. The information of the RRC layer will eventually become the information of the PHY layer, or be converted from the information of the PHY layer. Therefore, under this architecture, high-layer signaling (such as RRC layer signaling) can also be considered as being sent by the DU, or by the DU and the AAU.

[0084] Further, as shown in FIG. 1, the CU can be further divided into a control plane (CU control plane, CU-CP) and a user plane (CU user plane, CU-UP), and implemented by different entities, which are a control plane CU entity (CU-CP entity) and a user plane CU entity (CU-UP entity), respectively. Figure 2b

[0085] Optionally, in the network device structure shown in FIG. 1, the signaling generated by the CU can be sent to the terminal through the DU, or the signaling generated by the terminal can be sent to the CU through the DU. The DU can not analyze the signaling but directly transmit it to the terminal or the CU through protocol layer encapsulation. Figure 2a Figure 2b

[0086] ​​​​Optionally, the terminal 120 in the embodiments of the present application can be a user side device for implementing wireless communication function, such as a terminal or a chip used in a terminal, etc. The terminal can be a user equipment (UE), an access terminal, a terminal unit, a terminal station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless communication device, a terminal agent or a terminal device, etc. in a 5G network or a public land mobile network (PLMN) evolved after 5G. The access terminal can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device or a wearable device, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical treatment, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. Alternatively, the terminal can be a terminal with communication function in IoT, such as a terminal in V2X (e.g. a vehicle-mounted device), a terminal in D2D communication or a terminal in M2M communication, etc. The terminal can be mobile or fixed.

[0087] As shown in Figure 2c The terminal in the embodiments of the present application is provided with (or supports) a low power wake up receiver (LP-WUR) and a main radio (MR). The LP-WUR is provided with signal receiving function, and further can be provided with signal sending function. The main radio is provided with signal transceiving function.

[0088] Optionally, the LP-WUR and the main receiver can communicate with each other. The terminal can listen to a low power wake up signal (LP-WUS) through the LP-WUR, and after listening to the LP-WUS, the main receiver can be turned on / woken up for signal transmission and reception. The power consumption of the main receiver is higher than that of the LP-WUR.

[0089] In the process, when the terminal listens to the LP-WUS through the LP-WUR, the main receiver can be in a sleep state, and the LP-WUR determines whether to wake up the main receiver by listening to the LP-WUS. In the process, the terminal listens to the LP-WUS through the LP-WUR, which can ensure that the terminal receives the LP-WUS from the network device at any time and responds to the LP-WUS to determine whether to wake up the main receiver, which can improve the reliability of communication and effectively reduce the power consumption of the terminal.

[0090] In the process, the LP-WUR can be used for power-sensitive small terminals (such as industrial sensors, controllers, or wearable devices in Internet of Things scenarios); or the LP-WUR can be used for terminals in wireless scenarios (such as smart glasses, smart phones), without limitation.

[0091] Optionally, the LP-WUR and the main receiver can be two functional modules of the terminal, or can be two entities of the terminal. In hardware implementation, the LP-WUR and the main receiver can share a set of hardware resources, or can share part of the hardware resources, or can be implemented by two independent hardware resources, which is not limited in the present application.

[0092] In the embodiments of the present application, the LP-WUR can also be referred to as an LP-WUR link, and the main receiver can also be referred to as a main link. The terminal with the LP-WUR and the main receiver can be referred to as a dual connection terminal or a dual connection terminal. Of course, there can be other names, which are not limited.

[0093] The method provided by the embodiments of the present application will be described below with reference to the accompanying drawings. It can be understood that in the embodiments of the present application, the network device or the terminal can perform part or all of the steps in the embodiments of the present application, and these steps or operations are only examples, and the embodiments of the present application can also perform other operations or various operations. In addition, each step can be executed in a different order presented in the embodiments of the present application, and it is possible that not all operations in the embodiments of the present application are executed.

[0094] Exemplarily, the method provided in the following embodiments of the present application can be applied to the scenario of LP-WUS monitoring. Of course, the application scenario described herein is exemplary only and does not impose any limitation on the present application, and the application scenario of the method provided in the following embodiments of the present application is not specifically limited either, for example, the method can also be applied to the monitoring of other signals or other scenarios involving signals.

[0095] Optionally, as shown in Figure 3 In the NR system, the network device can transmit the LP-WUS in the manner of beam sweeping, that is, transmit multiple LP-WUS on different beams in a time-division multiplexing manner. Correspondingly, the network device can transmit the synchronization signal block (SSB) in the manner of beam sweeping, that is, transmit multiple SSBs on different beams in a time-division multiplexing manner. Exemplarily, as shown in Figure 3 The network device transmits the LP-WUS within the coverage of the LP-WUS and transmits the SSB within the coverage of the SSB; wherein the coverage of the LP-WUS can be smaller than the coverage of the SSB.

[0096] Optionally, in the radio resource control (RRC) connected state or the RRC active state and within the coverage of the LP-WUS, the terminal can monitor the LP-WUS, and when the terminal monitors the LP-WUS through the LP-WUR, the LP-WUR of the terminal can wake up the main receiver for signal transmission and reception (such as data transmission and reception). Exemplarily, the main receiver of the terminal can receive the paging message.

[0097] Exemplarily, the main receiver of the terminal can receive the physical downlink control channel (PDCCH) scrambled by the paging radio network temporary identifier (P-RNTI) during the running of the on duration timer, and receive the paging message in the system information or the physical downlink share channel (PDSCH) according to the paging downlink control information (DCI) in the PDCCH.

[0098] The terminal can listen to the LP-WUS in a time range in an RRC connected state or an RRC active state to reduce power consumption. The time range can be a paging cycle, or a connected discontinuous reception (CDRX) cycle, or a discontinuous reception (DRX), or a listening cycle of the LP-WUS, and the like.

[0099] For example, the CDRX cycle can include a plurality of low-power wake-up signal occasions (LP-WUS occasions, LOs), and the LP-WUR of the terminal can listen to the LP-WUS in the listening occasion LO. For example, as shown in Figure 4 If the LP-WUR of the terminal does not listen to the LP-WUS in the listening occasions LO1, LO2, and LO3, the LP-WUR of the terminal does not wake up the main receiver, i.e., the main receiver is in a sleep state. If the LP-WUR of the terminal listens to the LP-WUS in the listening occasion LO4, the LP-WUR of the terminal wakes up the main receiver.

[0100] Optionally, as shown in Figure 4 After the LP-WUR of the terminal wakes up the main receiver, the main receiver listens to the PDCCH during the running of the on duration timer to receive a paging message.

[0101] Optionally, the LP-WUS can include offset information. As shown in Figure 4 The offset information indicates the offset between the LP-WUS and the listening to the PDCCH. When the offset information is included in the LP-WUS, the LP-WUR of the terminal can delay waking up the main receiver after receiving the LP-WUS, and the length of the delay is the offset time indicated by the offset information.

[0102] Optionally, the offset information can include two levels of offset, for example, a radio frame level offset and a slot level offset. In this scenario, the length of the time offset indicated by the offset information is the length of the radio frame level offset plus the length of the slot level offset. Based on the two levels of offset, the accuracy of the time offset for waking up the main receiver is relatively loose, and is more suitable for the clock accuracy of the receiver.

[0103] Optionally, the LP-WUS can further include an identifier of the terminal (e.g., an ID of the terminal) to identify the terminal that needs to be woken up. After the LP-WUR of the terminal listens to the LP-WUS, the LP-WUR of the terminal can determine whether to wake up the main receiver according to the identifier of the terminal. At present, multiple identifiers of terminals can be included in the LP-WUS so as to wake up the main receivers of multiple terminals at one time. For example, the LP-WUS sent by the network device to the terminals in a cell includes terminal ID1, terminal ID2, terminal ID3 and terminal ID4, which respectively indicate terminal 1, terminal 2, terminal 3 and terminal 4. Correspondingly, after the terminal 1, the terminal 2, the terminal 3 and the terminal 4 in the cell receive the LP-WUS, it is found that the LP-WUS carries the identifier of the terminal itself, and the main receiver is woken up. However, if some terminals (e.g., terminal 1 and terminal 2) do not have data transmission and other services during the wake-up period, i.e., will not receive the paging message sent by the network side to wake up the data transmission, these terminals are in an invalid wake-up state, and the invalid wake-up state will increase the power consumption of the terminal. That is, using the existing scheme, some terminals that do not need to be woken up will be woken up, i.e., there is a problem of false wake-up, which leads to high power consumption of the terminal.

[0104] In addition, in some cases, if multiple terminals need to be woken up at the same time, the network device will send a wake-up signal to each of the multiple terminals to instruct the terminal to wake up the main receiver for data transmission. In this case, the network device sends a wake-up signal to each terminal, which will waste transmission resources.

[0105] Therefore, the embodiment of the present application provides a communication method, which can avoid false wake-up as much as possible by designing the transmission resource of the LP-WUS, so as to solve the problem of high false wake-up rate, thereby reducing the power consumption of the terminal.

[0106] As shown in FIG. 1, a communication method provided by an embodiment of the present application includes the following steps. Figure 5

[0107] S200, the network device acquires first wake-up information and second wake-up information.

[0108] The first wake-up information is used to indicate a terminal group (group ID) that needs to be woken up.

[0109] The second wake-up information is used to indicate a terminal sub-group (SG) in the terminal group that needs to be woken up. The terminal sub-group includes one or more terminals that need to be woken up.

[0110] ​Optionally, the first and second wake-up information can be pre-configured by the network device. For example, the network device can group multiple terminals with related CDRX cycles (e.g., the same CDRX cycle or CDRX cycles that are integer multiples of each other) into the same terminal group and configure a corresponding group number for that terminal group. Further, the network device can group terminals that need to be woken up within that terminal group into the same terminal subgroup and configure a corresponding subgroup number for that terminal subgroup; the network device can also group terminals that do not need to be woken up within that terminal group into the same terminal subgroup and configure a corresponding subgroup number for that terminal subgroup. Each terminal subgroup includes one or more terminals.

[0111] Optionally, the CDRX cycle corresponding to the terminal listening to LP-WUS can be pre-configured by the network device, or it can be specified by the protocol, etc., without limitation.

[0112] For example, such as Figure 6 As shown, assuming that terminal 1 and terminal 2 have the same CDRX period, and terminal 3's CDRX period is an integer multiple of the CDRX periods of terminal 1 and terminal 2, the network device can group terminals 1, 2, and 3 into the same terminal group and configure a corresponding group number (e.g., G17) for this terminal group. Optionally, in this terminal group, terminals 2 and 3 need to be woken up, while terminal 1 does not. Based on this, the network device can group terminal 1 into the same terminal subgroup and configure a corresponding subgroup number (e.g., SG1) for this terminal subgroup. Similarly, the network device can group terminals 2 and 3 into the same terminal subgroup and configure a corresponding subgroup number (e.g., SG2) for this terminal subgroup.

[0113] S201. The network device sends LP-WUS, and correspondingly, the first terminal listens to LP-WUS through LP-WUR.

[0114] The first terminal can be any terminal in the cell served by the network device. The first terminal has... Figure 2c The diagram shows the LP-WUS and the main receiver. Optionally, the network device can transmit LP-WUS via beam scanning, that is, transmit multiple LP-WUS on different beams. Based on this, terminals in RRC connected or RRC active state and within the coverage area of ​​LP-WUS can listen to LP-WUS.

[0115] The LP-WUS carries the first wake-up information and the second wake-up information obtained in the S200. In this application, the LP-WUS carrying the first wake-up information and the second wake-up information can include one or two. The first wake-up information and the second wake-up information can be carried in the LP-WUS in the same information format or in different information formats. Specifically, the information format of the first wake-up information and the second wake-up information can refer to the following cases one to four, which will not be described here.

[0116] In an example, the LP-WUS includes a first wake-up signal (such as LP-WUS1). In this case, the first wake-up signal includes the first wake-up information and the second wake-up information, in other words, the first wake-up information and the second wake-up information are carried in the same LP-WUS. For example, as shown in the following figure, Figure 7 The first wake-up signal (such as LP-WUS1) is composed of two parts, one part is used to carry the first wake-up information, and the other part is used to carry the second wake-up information, that is, the two wake-up information are carried in the same wake-up signal. In this scenario, the first terminal can listen to the first wake-up information and the second wake-up information on part or all of the resources of the same time domain resource through the LP-WUR.

[0117] In another example, the LP-WUS includes a second wake-up signal (such as LP-WUS2) and a third wake-up signal (such as LP-WUS3), in other words, the first wake-up information and the second wake-up information are carried in two different LP-WUS. In this case, the second wake-up signal includes the first wake-up information, and the third wake-up signal includes the second wake-up information. For example, as shown in the following figure, Figure 7 The second wake-up signal (such as LP-WUS2) is used to carry the first wake-up information, and the third wake-up signal (such as LP-WUS3) is used to carry the second wake-up information, that is, the first wake-up information and the second wake-up information are carried in two different wake-up signals. In this scenario, the first terminal can listen to the first wake-up information and the second wake-up information on part or all of the resources of the same frequency domain resource through the LP-WUR.

[0118] In this application, the first terminal listening to the LP-WUS through the LP-WUR can be understood as the LP-WUR of the first terminal being turned on, and the LP-WUR of the first terminal listening to the LP-WUS. Optionally, the LP-WUR of the first terminal can listen to the LP-WUS on the MO in the DRX cycle, and the DRX cycle and the MO can be protocol predefined or preconfigured to the first terminal by the network device.

[0119] In an embodiment, one DRX cycle can include multiple LOs, one LO can include multiple monitoring occasions (MOs), and the first terminal can monitor the LP-WUS in the MOs via the LP-WUR. Optionally, each of the multiple MOs can have one or more wake-up signals. For example, in a case where the first wake-up information and the second wake-up information are carried in the same LP-WUS, the MO has one wake-up signal, and the first terminal can monitor one wake-up signal in the MO via the LP-WUR. For another example, in a case where the first wake-up information and the second wake-up information are carried in two different LP-WUS respectively, the MO has multiple wake-up signals, and the first terminal can monitor multiple wake-up signals in the MO via the LP-WUR.

[0120] For example, in a case where one LO corresponds to MO1, MO2 and MO3, as shown in FIG. 3, in a case where the MO1 has one wake-up signal, the first terminal can monitor one wake-up signal in the MO1 via the LP-WUR, such as LP-WUS1. In a case where the MO1 has multiple (e.g., two) wake-up signals, the first terminal can monitor two wake-up signals in the MO1 via the LP-WUR, such as LP-WUS2 and LP-WUS3. Figure 8

[0121] Optionally, in a case where the first wake-up information and the second wake-up information are carried in the same LP-WUS, the first terminal monitors one wake-up signal (which can be referred to as the first wake-up signal) via the LP-WUR. At this time, the first terminal monitoring the first wake-up signal via the LP-WUR can include:

[0122] The first terminal monitors the first wake-up information carried by the first wake-up signal via the LP-WUR; in a case where the group number of the terminal group indicated by the first wake-up information needs to be woken up is the same as the group number of the terminal group to which the first terminal belongs, the first terminal monitors the second wake-up information carried by the first wake-up signal via the LP-WUR. Alternatively, in a case where the first terminal does not monitor the first wake-up information carried by the first wake-up signal via the LP-WUR, the first terminal cancels monitoring the second wake-up information carried by the first wake-up signal via the LP-WUR. Alternatively, in a case where the first terminal does not monitor the first wake-up information carried by the first wake-up signal via the LP-WUR, the first terminal continues to monitor the second wake-up information carried by the first wake-up signal via the LP-WUR.

[0123] Optionally, in a case where the first wake-up information and the second wake-up information are carried in two different LP-WUS respectively, the first terminal monitors two wake-up signals (e.g., the first wake-up signal and the second wake-up signal) via the LP-WUR, and at this time, the first terminal monitoring the first wake-up signal and the second wake-up signal via the LP-WUR can include:​

[0124] The first terminal monitors the second wake-up signal through the LP-WUR; in a case where the group number of the terminal group that needs to be woken up indicated by the first wake-up information included in the second wake-up signal is the same as the group number of the terminal group in which the first terminal is located, the first terminal monitors the third wake-up signal through the LP-WUR. Or, in a case where the first terminal does not monitor the second wake-up signal through the LP-WUR, the first terminal cancels monitoring the third wake-up signal through the LP-WUR. Or, in a second case where the first terminal does not monitor the second wake-up signal through the LP-WUR, the first terminal continues to monitor the third wake-up signal through the LP-WUR.

[0125] S202, in a case where the first terminal determines, according to the LP-WUS, that the terminal that needs to be woken up in the terminal group includes the first terminal, waking up the main receiver.

[0126] Optionally, in a case where the group number of the terminal group that needs to be woken up indicated by the first wake-up information is the same as the group number of the terminal group in which the first terminal is located, the first terminal determines, according to the LP-WUS, that the terminal that needs to be woken up in the terminal group includes the first terminal.

[0127] Or, optionally, in a case where the sub-group number of the terminal sub-group that needs to be woken up in the terminal group indicated by the second wake-up information is the same as the sub-group number of the terminal sub-group in which the first terminal is located, the first terminal determines, according to the LP-WUS, that the terminal that needs to be woken up in the terminal group includes the first terminal.

[0128] Or, optionally, in a case where the group number of the terminal group that needs to be woken up indicated by the first wake-up information is the same as the group number of the terminal group in which the first terminal is located, and the sub-group number of the terminal sub-group that needs to be woken up in the terminal group indicated by the second wake-up information is the same as the sub-group number of the terminal sub-group in which the first terminal is located, the first terminal determines, according to the LP-WUS, that the terminal that needs to be woken up in the terminal group includes the first terminal, which is not limited.

[0129] In the above scheme, on the one hand, the network device divides a plurality of terminals associated with a CDRX cycle in the same terminal group, in which case the network device can send a wake-up signal to a plurality of terminals in the same terminal group on the same time domain resource, thereby avoiding wasting transmission resources.

[0130] Further, on the other hand, the network device sends a wake-up signal carrying first wake-up information and second wake-up information, the first wake-up information indicating a terminal group that needs to be woken up, and the second wake-up information indicating a terminal in the terminal group that needs to be woken up; that is, the network device can indicate a specific terminal in the terminal group that needs to be woken up, thereby solving the problem of false wake-up and reducing the false wake-up rate.

[0131] Further, after the first terminal listens to the wake-up signal from the network device, in a case that the first terminal is included in the terminals in the terminal group that need to be woken up based on the first wake-up information and the second wake-up information carried in the wake-up signal, the first terminal wakes up the master receiver, so that the first terminal can be avoided in the invalid wake-up state, and the power consumption of the terminal is reduced.

[0132] Optionally, in the embodiment of the present application, in order to facilitate the first terminal to accurately listen to the LP-WUS, the network device needs to configure the information format of the payload content (i.e. the wake-up information) in the LP-WUS to the first terminal in advance, so that the first terminal can parse the payload content in the LP-WUS according to the pre-configured information, and then obtain the wake-up information. For example, the method further includes:

[0133] The network device sends third signaling to the first terminal, and correspondingly, the first terminal receives the third signaling from the network device.

[0134] The third signaling can be any one of the following signaling: system information broadcast (SIB), master information block (MIB), broadcast message, RRC signaling, paging message, medium access control (MAC) control element (CE), downlink control information (DCI) signaling, PDCCH, PDSCH, channel state information reference signal (CIS-RS), demodulation reference signal (DMRS), tracking reference signal (TRS), paging message, short message; or the third signaling can also be located in any new signal, channel or signaling, which is not limited.

[0135] The third signaling can indicate that the information format of the load content (i.e., the wake-up information) in the LP-WUS is a first information format from a plurality of information formats, and the plurality of information formats include: indicating one or more terminals that need to be woken up by using a bit map, indicating one or more terminals that need to be woken up by using an encoded format, indicating part of the terminals that need to be woken up from a plurality of terminals having the same terminal identifier by using an encoded format, indicating one or more terminal groups that need to be woken up by using an encoded format, indicating one or more terminals that need to be woken up by using a bit block, indicating a terminal group that needs to be woken up by using an encoded format, and indicating a sub-group of terminals in the terminal group that need to be woken up by using a bit map; and the first information format is: indicating a terminal group that needs to be woken up by using an encoded format, and indicating a sub-group of terminals in the terminal group that need to be woken up by using a bit map.

[0136] In an example, the network device can pre-configure the information format of the load content in the LP-WUS to the first terminal in a static configuration manner. The static configuration manner refers to that the network device pre-configures all the plurality of information formats to the first terminal. Subsequently, the network device can carry the first field indicating the information format in the third signaling and send the third signaling to the first terminal, so that the first terminal parses the load content in the LP-WUS according to the information format indicated by the network device, and further obtains the wake-up information.

[0137] Optionally, the network device sends the first indication information to the first terminal, and correspondingly, the first terminal receives the first indication information from the network device.

[0138] The first indication information includes a first field, a second field, a third field, a fourth field, a fifth field, and a sixth field. The value of the field can represent an information format. For example, when the value of the first field is "0", it can represent information format 1 (e.g., indicating one or more terminals that need to be woken up by using a bit map); when the value of the second field is "1", it can represent information format 2 (e.g., indicating one or more terminals that need to be woken up by using an encoded format); when the value of the third field is "00", it can represent information format 3 (e.g., indicating part of the terminals that need to be woken up from a plurality of terminals having the same terminal identifier by using an encoded format); when the value of the fourth field is "01", it can represent information format 4 (e.g., indicating one or more terminal groups that need to be woken up by using an encoded format); when the value of the fifth field is "10", it can represent information format 5 (e.g., indicating one or more terminals that need to be woken up by using a bit block); and when the value of the sixth field is "11", it can represent information format 6 (e.g., indicating a terminal group that needs to be woken up by using an encoded format, and indicating a sub-group of terminals in the terminal group that need to be woken up by using a bit map).

[0139] Optionally, after the network device pre-configures the multiple information formats to the first terminal, the third signaling sent by the network device to the first terminal can include a sixth field, i.e., the information format of the content of the LP-WUS is information format 6 (i.e., the first information format).

[0140] In another example, the network device can pre-configure the information format of the content of the LP-WUS to the first terminal in a dynamic configuration manner. The dynamic configuration manner refers to that the network device pre-configures the information format of the content of the LP-WUS to the first terminal before each time of sending the LP-WUS.

[0141] Optionally, the network device sends the third signaling to the first terminal before sending the LP-WUS, and the third signaling indicates that the information format of the content of the LP-WUS is the first information format. For example, the third signaling includes a target field, and the value of the target field indicates that the terminal group that needs to be woken up is indicated in a coded format, and the terminal subgroup in the terminal group that needs to be woken up is indicated in a bitmap (i.e., the first information format is information format 6 in the multiple information formats).

[0142] Optionally, in the embodiments of the present application, the first wake-up information and the second wake-up information can be carried in the LP-WUS in different or same information formats (or simply formats). For the convenience of description, the information format of the wake-up information is simply referred to as the format of the wake-up information, which is uniformly described here. For example, the format of the first wake-up information is the first format, the format of the second wake-up information is the second format; or the format of the first wake-up information is the second format, the format of the second wake-up information is the first format; or the format of the first wake-up information is the first format, the format of the second wake-up information is the first format; or the format of the first wake-up information is the second format, the format of the second wake-up information is the second format, etc., which are not limited. The first format and the second format are different, and the first format and the second format refer to the information formats in the above embodiments.

[0143] Optionally, the first format is a code point format, and the second format is a bitmap format; or the first format is a bitmap format, and the second format is a code point format. The code point format can refer to that the information to be processed is encoded by using a binary bit, so that the value of the binary bit obtained by encoding is equal to the value of the information. The bitmap format can refer to that the information to be processed is combined by using one or more binary bits, so that the value of the binary bit obtained by combining indicates the information to be processed. Of course, the first format and the second format can also be other formats, which are not limited.

[0144] The present application takes the coding format and the bitmap format as examples, and lists four combinations of the format of the first wake-up information and the format of the second wake-up information respectively.

[0145] Case one, the first wake-up information is carried in the LP-WUS in the coding format, and the second wake-up information is carried in the LP-WUS in the bitmap format.

[0146] Optionally, the first wake-up information in the coding format can include a plurality of bits obtained by encoding the first wake-up information, which can be referred to as bits occupied by the first wake-up information, and the value of the number of bits occupied by the first wake-up information is the group number of the terminal group (i.e., the value of the bits of the first wake-up information is the group number of the terminal group). Wherein, the value of the number of bits can be understood as: the sequence of the number of bits is converted into a decimal value; or, the sequence of the number of bits is converted into a hexadecimal value, etc., which is not limited.

[0147] Optionally, the second wake-up information in the bitmap format can include a bitmap, which can indicate the sub-group number and the corresponding relationship between the bitmap and the sub-group number, and the bitmap includes at least one bit; one bit corresponds to one terminal sub-group in the terminal group, and the value of the bit is used to indicate whether the terminal sub-group corresponding to the bit needs to be woken up.

[0148] It can be understood that the current protocol stipulates that the load size that can be carried by the LP-WUS does not exceed 8 bits or 16 bits. Taking the load size carried by the LP-WUS as 16 bits as an example, as shown in Figure 9a , the number of bits occupied by the first wake-up information is 8 bits, and the number of bits occupied by the second wake-up information is 8 bits.

[0149] Optionally, assuming that the sequence of the number of bits occupied by the first wake-up information is {00010001}, the sequence is converted into a decimal value of 17, that is, the first wake-up information indicates that the group number of the terminal group that needs to be woken up is 17. Correspondingly, assuming that the sequence of the bitmap corresponding to the number of bits occupied by the second wake-up information is {00010001}, the corresponding relationship between the bitmap and the sub-group number can be as shown in Table 1.

[0152] Optionally, as shown in Table 1, assuming that the second wake-up information indicates that the sub-group number of the terminal sub-group in the terminal group that needs to be woken up is 1, according to the above-mentioned corresponding relationship, the sub-group number 1 corresponds to the first bit (or bit 1) in the bitmap, the terminal sub-group corresponding to the bit 1 includes UE1 and UE2, and the value of the bit 1 is 1, then the second wake-up information indicates that the terminal sub-group (i.e., UE1 and UE2) in the terminal group needs to be woken up.

[0153] Optionally, as shown in Table 1, assuming that the subgroup number of the terminal subgroup that needs to be woken up in the second wake-up information indicates that the subgroup number is 2, according to the above correspondence, the subgroup number 2 corresponds to the second bit (or bit 2) in the bit diagram. The terminal subgroups corresponding to bit 2 include UE3 and UE4, and the value of bit 2 is 0. In this case, the terminal subgroups (i.e., UE3 and UE4) in the second wake-up information indicate that they do not need to be woken up.

[0154] It is understood that in this embodiment, the first terminal listens to LP-WUS, and LP-WUS includes first wake-up information and second wake-up information. The first wake-up information indicates that the terminal group that needs to be woken up is group 17, and the second wake-up information indicates that the terminal subgroups that need to be woken up in the terminal group include group 1 and group 5. That is to say, the LP-WUS listened to by the first terminal indicates that the terminals that need to be woken up include UE1, UE2, UE9, and UE10.

[0155] It should be noted that the 8-bit number of bits occupied by the first wake-up information and the 8-bit number of bits occupied by the second wake-up information are merely illustrative examples of the number of bits occupied by the first and second wake-up information in this application. The number of bits occupied by the first and second wake-up information can also have other values. For example, the first wake-up information may occupy 12 bits and the second wake-up information may occupy 4 bits; or the first wake-up information may occupy 6 bits and the second wake-up information may occupy 10 bits; or the first wake-up information may occupy 2 bits and the second wake-up information may occupy 14 bits, etc. This application does not specifically limit these values.

[0156] For example, such as Figure 9b As shown, the first wake-up information occupies 12 bits, and the second wake-up information occupies 4 bits. Optionally, assuming the bit sequence of the first wake-up information is {000100010001}, then the decimal value of this bit sequence is 273. Therefore, the first wake-up information indicates that the group number of the terminal group that needs to be woken up is 273. Assuming the bit sequence corresponding to the second wake-up information is {1000}, the correspondence between this bit sequence and the subgroup number can be shown in Table 2.

[0157] Table 2

[0158]

[0159] Optionally, as shown in Table 2, assuming that the subgroup number of the terminal subgroup that needs to be woken up in the second wake-up information indicates that the second wake-up information indicates that the subgroup number of the terminal subgroup that needs to be woken up is 4, according to the above correspondence, the subgroup number 4 corresponds to the fourth bit in the bit diagram (or bit 4), the terminal subgroups corresponding to bit 4 include UE28 and UE29, and the value of bit 4 is 1, then the second wake-up information indicates that the terminal subgroups (i.e. UE28 and UE29) in the terminal group need to be woken up.

[0160] Optionally, as shown in Table 2, assuming that the subgroup number of the terminal subgroup that needs to be woken up in the second wake-up information indicates that the subgroup number is 1, according to the above correspondence, the subgroup number 1 corresponds to the first bit (or bit 1) in the bit diagram. The terminal subgroups corresponding to bit 1 include UE23, UE24 and UE25, and the value of bit 1 is 0. In this case, the terminal subgroups (i.e. UE23, UE24 and UE25) in the second wake-up information indicate that they do not need to be woken up.

[0161] It is understood that in this embodiment, the first terminal listens to LP-WUS, and LP-WUS includes first wake-up information and second wake-up information. The first wake-up information indicates that the terminal group that needs to be woken up is group 273, and the second wake-up information indicates that the terminal subgroup that needs to be woken up in the terminal group includes group 4. That is to say, the terminals that the first terminal listens to instruct to be woken up by LP-WUS include UE28 and UE29.

[0162] Taking an 8-bit payload carried by LP-WUS as an example, for instance, Figure 9c As shown, the first wake-up information occupies 4 bits, and the second wake-up information occupies 4 bits. Optionally, assuming the sequence of bits occupied by the first wake-up information is {1000}, then the decimal value of this bit sequence is 8, meaning the first wake-up information indicates that the group number of the terminal group to be woken up is 8. Correspondingly, assuming the sequence of bits occupied by the second wake-up information is {0100}, the correspondence between this bit diagram and the subgroup number can be shown in Table 3.

[0163] Table 3

[0164]

[0165] Optionally, as shown in Table 3, assuming that the subgroup number of the terminal subgroup that needs to be woken up in the second wake-up information indicates that the second wake-up information indicates that the subgroup number of the terminal subgroup that needs to be woken up is 3, according to the above correspondence, the subgroup number 3 corresponds to the third bit in the bit diagram (or bit 3), the terminal subgroup corresponding to bit 3 includes UE34, and the value of bit 3 is 1, then the second wake-up information indicates that the terminal subgroup (i.e. UE34) in the terminal group needs to be woken up.

[0166] Optionally, as shown in Table 2, assuming that the second wake-up information indicates that the sub-group number of the terminal sub-group in the terminal group that needs to be woken up is 2, according to the above correspondence relationship, the sub-group number 2 corresponds to the second bit (or bit 2) in the bit map, the terminal sub-group corresponding to the bit 2 includes the UE 33, and the value of the bit 2 is 0, then the second wake-up information indicates that the terminal sub-group (i.e. the UE 33) in the terminal group does not need to be woken up.

[0167] It can be understood that in this embodiment, the first terminal listens to the LP-WUS, and the LP-WUS includes the first wake-up information and the second wake-up information, the first wake-up information indicates that the terminal group that needs to be woken up is the 8th group, and the second wake-up information indicates that the terminal sub-group in the terminal group that needs to be woken up includes the 3rd group. That is, the LP-WUS listened to by the first terminal indicates that the terminal that needs to be woken up includes the UE 34.

[0168] It should be noted that the correspondence between the bit map and the sub-group number shown in Tables 1, 2 and 3 is only an example. Of course, the correspondence can also be implemented in other forms, for example, the correspondence can be implemented in the form of key-value pair; or the correspondence can also be implemented in the form of array, without limitation.

[0169] In addition, the correspondence between the sub-group number and the terminal sub-group shown in Tables 1, 2 and 3 is only an example. Of course, the sub-group number shown in Tables 1, 2 and 3 can also correspond to other terminal sub-groups, for example, the sub-group number 1 corresponds to the UE 11 and the UE 12, the sub-group number 2 corresponds to the UE 22 and the UE 23, etc., without limitation.

[0170] Case two, the first wake-up information is carried in the LP-WUS in the form of a bit map, and the format of the second wake-up information is carried in the LP-WUS in the form of an encoding format.

[0171] Optionally, the first wake-up information in the form of a bit map includes a bit map, which can indicate the group number and the correspondence between the bit map and the group number, the bit map includes at least one bit, one bit corresponds to one terminal group, and the value of the bit is used to indicate whether the terminal group corresponding to the bit needs to be woken up.

[0172] Optionally, the second wake-up information in the form of an encoding format can include a plurality of bits obtained by encoding the second wake-up information, the plurality of bits can be referred to as the bits occupied by the second wake-up information, and the value of the number of bits occupied by the second wake-up information is the sub-group number of the terminal sub-group.

[0173] Taking the load size of the LP-WUS as 8 bits as an example, an example is shown as follows. Figure 10As shown, the first wake-up information occupies 4 bits, and the second wake-up information occupies 4 bits. Optionally, assuming that the sequence of the number of bits occupied by the first wake-up information is {1000}, the correspondence between the bit pattern and the group number can be as shown in Table 4.

[0174] Table 4

[0175]

[0176] Optionally, as shown in Table 4, assuming that the first wake-up information indicates that the group number of the terminal group that needs to be woken up is 4, according to the above correspondence, the group number 4 corresponds to the fourth bit (or bit 4) in the bit pattern, the terminal group corresponding to bit 4 includes UEs 51-70, and the value of bit 4 is 1, then the first wake-up information indicates that the terminal group (i.e., UEs 51-70) needs to be woken up.

[0178] Optionally, as Figure 10 shown, assuming that the sequence of the number of bits occupied by the second wake-up information is {1000}, then the sequence of the number of bits is converted to a decimal value of 8, that is, the second wake-up information indicates that the sub-group number of the terminal sub-group in the terminal group that needs to be woken up is 8.

[0179] In this embodiment, the first terminal listens to the LP-WUS, and the LP-WUS includes the first wake-up information and the second wake-up information, the first wake-up indicates that the terminal group that needs to be woken up is the 4th group, and the second wake-up information indicates that the terminal sub-group in the terminal group that needs to be woken up is the 8th group. That is, the LP-WUS listened to by the first terminal indicates that the terminal that needs to be woken up is the terminal sub-group 8 (such as: terminal UE 60) in the terminal group 4 (i.e., UEs 51-70).

[0180] Optionally, the number of bits occupied by the second wake-up information includes a plurality of subsequences, and each subsequence in the plurality of subsequences has a value of a sub-group number of a terminal sub-group. Illustratively, as shown in Figure 10 assuming that the plurality of subsequences included in the number of bits occupied by the second wake-up information is {10} and {11}, then the subsequence {10} is converted to a decimal value of 2, and the subsequence {11} is converted to a decimal value of 3, that is, the second wake-up information indicates that the sub-group number of the terminal sub-group in the terminal group that needs to be woken up is 2 and 3.

That is, the LP-WUS listened to by the first terminal indicates that the terminal to be woken up is the terminal subgroup 2 (such as: terminal UE53) and the terminal subgroup 3 (such as: terminal UE54) in the terminal group 4 (that is, UE51-UE70).

[0182] It should be noted that the correspondence between the bit pattern and the group number shown in Table 4 is only an example. Of course, the above correspondence can also be implemented in other forms, for example, the above correspondence can be implemented in the form of key-value pair; or the above correspondence can also be implemented in the form of array, without limitation.

[0183] In addition, the correspondence between the group number shown in Table 4 and the terminal group is only an example. Of course, the group number shown in Table 4 can also correspond to other terminal groups, for example, group number 1 corresponds to UE1-UE10, group number 2 corresponds to UE11-UE20, etc., without limitation.

[0184] It should be noted that the above bit number occupied by the load size carried by the LP-WUS, the bit number occupied by the first wake-up information, and the bit number occupied by the second wake-up information are only an example. Of course, the load size carried by the LP-WUS can also be 12 bits, the bit number occupied by the first wake-up information can also be 8 bits, and the bit number occupied by the second wake-up information can also be 4 bits; or the load size carried by the LP-WUS can also be 4 bits, the bit number occupied by the first wake-up information can also be 2 bits, and the bit number occupied by the second wake-up information can also be 2 bits, etc., without limitation.

[0191] Among them, the number of bits occupied by the second wake-up information is obtained according to the number of bits occupied by the first wake-up information, which can be understood as: the number of bits occupied by the second wake-up information is the difference between the number of bits occupied by the LP-WUS and the number of bits occupied by the first wake-up information. Correspondingly, the number of bits occupied by the first wake-up information is obtained according to the number of bits occupied by the second wake-up information, which can be understood as: the number of bits occupied by the first wake-up information is the difference between the number of bits occupied by the LP-WUS and the number of bits occupied by the second wake-up information.

[0195] The first signaling is used to indicate the number of bits occupied by the first wake-up information and the number of bits occupied by the second wake-up information. Optionally, in the case where the formats of the first wake-up information and the second wake-up information are configured by the network device, the first signaling is further used to indicate the format of the first wake-up information and the format of the second wake-up information.

[0196] Optionally, the first signaling includes a first field and a second field. For example, the first field indicates that the format of the first wake-up information is a first format, and the second field indicates that the format of the second wake-up information is a second format. For example, the first field is "1", which indicates that the first wake-up information is carried in the LP-WUS in an encoded format, i.e., the first field indicates that the value of the number of bits occupied by the first wake-up information is the group number of the terminal group. The second field is "0", which indicates that the second wake-up information is carried in the LP-WUS in a bitmap format, i.e., the second field indicates that the second wake-up information includes a bitmap, the bitmap indicates a sub-group number and a correspondence between the bitmap and the sub-group number, and the bitmap includes at least one bit. One bit corresponds to one terminal sub-group in the terminal group, and the value of the bit is used to indicate whether the terminal sub-group corresponding to the bit needs to be woken up.

Alternatively, the first signaling can also be located in any new signal, channel or signaling, without limitation.

[0198] Taking the first signaling as SIB (such as SIB1) as an example, the first signaling can be, for example, SIB1 ("1": 8; "0": 8). Here, "1" represents the first field, "0" represents the second field, and 8 represents the number of bits occupied by the first wake-up information and the second wake-up information.

[0199] Taking the first signaling as RRC signaling as an example, the first signaling can be, for example, RRCSetup ("1": 8; "0": 8), or enable LPWUS triggered PDCCH monitoring ("1": 8; "0": 8), etc., without limitation.

[0200] Optionally, the group number of the terminal group to which the first terminal belongs and the sub-group number of the terminal sub-group to which the first terminal belongs are configured by the network device. In this scenario, as shown in FIG. 2C, the method further includes, before step S200c: Figure 12

[0201] ​S200b, the network device sends the second signaling to the first terminal. Correspondingly, the first terminal receives the second signaling sent from the network device.

Alternatively, the second signaling can be located in any new signal, channel or signaling, without limitation.

[0205] Taking the second signaling as RRC signaling as an example, the second signaling can be, for example, RRCSetup (G17; SG1), or the first signaling can be, for example, enable LPWUS triggered PDCCH monitoring (G17; SG1), without limitation. Wherein, “G17” indicates the group number of the terminal group to which the first terminal belongs; and “SG1” indicates the subgroup number of the terminal subgroup to which the first terminal belongs.

Here, "module" can refer to an application-specific integrated circuit (ASIC), a circuit, a processor and memory that executes one or more software or firmware programs, integrated logic circuits, and / or other devices that can provide the above functions.

[0232] In some embodiments, when Figure 13 When the communication device is a chip or chip system, the function / implementation process of the transceiver module 1101 can be implemented through the input / output interface (or communication interface) of the chip or chip system, and the function / implementation process of the processing module 1102 can be implemented through the processor (or processing circuit) of the chip or chip system.

[0233] Since the communication device 110 provided in this embodiment can execute the above method, the technical effects it can achieve can be referred to the above method embodiment, and will not be repeated here.

[0234] As a possible product form, the first terminal device or the network device described in the embodiments of the present application can also be implemented using one or more field programmable gate arrays (FPGA), programmable logic devices (PLD), controllers, state machines, gate logic, discrete hardware components, any other suitable circuit, or any combination of circuits capable of performing the various functions described throughout the present application

[0235] As another possible product form, the first terminal or network device described in the embodiments of the present application can be implemented by a general bus architecture. For ease of illustration, reference is made to Figure 14 , Figure 14 is a structural schematic diagram of a communication apparatus 1200 provided by the embodiments of the present application, which includes a processor 1201 and a transceiver 1202. The communication apparatus 1200 can be a network device, or a chip or chip system therein; or the communication apparatus 1200 can be a first terminal, or a chip or module therein. Figure 14 Only the main components of the communication apparatus 1200 are shown. In addition to the processor 1201 and the transceiver 1202, the communication apparatus can further include a memory 1203, and an input and output device (not shown). Figure 14

[0238] ​When the communication device is powered on, the processor 1201 can read the software program in the memory 1203, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be transmitted wirelessly, the processor 1201 performs baseband processing on the data to be transmitted and outputs the baseband signal to the radio frequency (RF) circuit.
