Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to paging methods and apparatus. Background Technology

[0002] For terminal devices in an idle or inactive state, the network-side device transmits downlink control information (DCI) on the physical downlink control channel (PDCCH) corresponding to the paging occasion (PO), enabling the terminal to receive the DCI. The DCI indicates the time-frequency resources of the physical downlink shared channel (PDSCH). Furthermore, the network-side device can transmit a paging message on the time-frequency resources of this PDSCH; correspondingly, the terminal can receive the paging message on the time-frequency resources of this PDSCH. This process is called the paging procedure.

[0003] Typically, the paging process is initiated by a wake-up signal (WUS), which indicates whether paging should be performed during a discontinuous reception (DRX) cycle. Furthermore, to reduce WUS power consumption, low-power WUS (LP-WUS) was introduced in 3GPP Release 18 (Rel18 or R18) and Release 19 (Rel19 or R19).

[0004] Therefore, how to initiate an effective paging process based on LP-WUS is an urgent problem to be solved. Summary of the Invention

[0005] This application provides a paging method and apparatus that can initiate an effective paging process based on LP-WUS, thereby improving paging capacity.

[0006] Firstly, this application provides a paging method, which can be executed by a first communication device. Unless otherwise specified, the "first communication device" in this application can refer to a first communication equipment, a component of the first communication equipment (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the first communication equipment. The method includes: receiving a first signal from a second communication device on a first resource, the first signal being used to wake up the first communication device, the first signal being carried on a first beam of the second communication device; and receiving paging messages from N third communication devices according to M second resources corresponding to the first beam, wherein the second and third communication devices are located in the same area, and M and N are both integers greater than or equal to 1.

[0007] Based on the first aspect, the first beam of the second communication device used to send a wake-up signal (i.e., the first signal) is associated with the paging resources of the third communication device. In the paging process, N third communication devices send paging messages according to the second resources corresponding to the first beam of the second communication device, and the first communication device receives the paging messages according to the M second resources corresponding to the first beam. Compared to sending paging messages simultaneously according to all resources corresponding to the second communication device (e.g., resources corresponding to multiple beams), this reduces paging power consumption and paging resource consumption, thereby increasing paging capacity.

[0008] In one possible design, receiving paging messages from N third communication devices based on M second resources corresponding to the first beam includes: determining M second resources based on the first beam; receiving M first indication information on the M second resources, wherein the M second resources correspond one-to-one with the M first indication information, and the first indication information indicates the third resource used to carry the paging message; and receiving the paging message based on the M first indication information.

[0009] Based on this possible design, in the paging process, the information carried at the paging time (i.e., the second resource) can typically indicate the resource used to carry the paging message (i.e., the third resource). Therefore, after the first communication device determines M second resources, it can receive the paging message according to the information carried on the second resources (i.e., the first indication information) to realize paging of the first communication device by the network side.

[0010] In one possible design, the M second resources are the paging opportunities of the M resources corresponding to the identifier of the first beam in the first correspondence, and the first correspondence includes the correspondence between the identifier of at least one beam and at least one resource.

[0011] Based on this possible design, a correspondence between different beams and second resources (i.e., a first correspondence) can be established in advance. After obtaining the identifier of the first beam, the first communication device can directly determine the second resource corresponding to the first beam speed in the correspondence. This improves the efficiency of determining the second resource and thus improves the efficiency of paging based on the second resource.

[0012] In one possible design, before receiving paging messages from N third communication devices based on M second resources corresponding to the first beam, the method further includes: receiving second indication information, the second indication information indicating the first correspondence.

[0013] Based on this possible design, the first correspondence can be pre-indicated by signaling (i.e., the second indication information), so that after obtaining the identifier of the first beam, the first communication device can directly determine the second resource corresponding to the first beam speed in the correspondence; thereby improving the efficiency of determining the second resource and thus improving the efficiency of paging based on the second resource.

[0014] In one possible design, the first correspondence also includes the identification of at least one beam, at least one resource, and a correspondence between at least one first parameter, the first parameter including at least one of the following types of parameters: offset value, identification of the third communication device, and identification of the terminal device.

[0015] In one possible design, when the first parameter includes the identifier of the terminal device, at least one first parameter includes the identifier of at least one terminal device, and at least one terminal device includes a first communication device; determining M second resources based on the first beam includes: determining M second resources based on the first beam and the identifier of the first communication device.

[0016] Based on this possible design, in addition to establishing the correspondence between different beams and the paging devices (or third communication devices) associated with the second communication device and different paging times (i.e., multiple second resources), it is also possible to further establish the correspondence between the identifiers of different paged devices (such as terminal devices) and different beams and different paging times, so that different paged devices can paging according to different resources, avoiding the reduction in paging efficiency caused by all paged devices under the same beam occupying the same resources.

[0017] In one possible design, when the first parameter includes an offset value, at least one first parameter includes multiple offset values; determining M second resources based on the first beam includes: determining M second resources based on the first beam and the first offset value, wherein at least one offset value includes the first offset value.

[0018] In one possible design, before determining M second resources based on the first beam and the first offset value, the method further includes: receiving third indication information from a second communication device, the third indication information indicating the first offset value.

[0019] Based on the two possible designs described above, and in addition to establishing the correspondence between different paging times (i.e., multiple second resources) of paging devices (third communication devices) associated with different beams and second communication devices, it is also possible to consider creating a larger interval between the second resources of the third communication devices in different beam directions. This provides the first communication device with more options during the mobility relationship process. Therefore, offset values ​​can be indicated for the third communication devices in different beam directions, so that there is a larger interval (e.g., the interval is greater than or equal to a first threshold) between the second resources of the third communication devices in different beam directions determined by the first communication device based on the offset value and the beam identifier. This provides the first communication device with more options during the mobility relationship process. Furthermore, the offset value can be flexibly determined based on the network side requirements to improve the flexibility of second resource configuration.

[0020] In one possible design, when the first parameter includes the identifier of the third communication device, at least one third communication device includes N third communication devices; determining M second resources based on the first beam includes: determining M second resources based on the first beam and the identifier of the third communication device.

[0021] Based on this possible design, in addition to establishing the correspondence between different beams and the paging devices (or third communication devices) associated with the second communication device and different paging times (i.e., multiple second resources), it is also possible to further establish the identification of the paging device (such as the third communication device) and the correspondence between different beams and different paging times. This allows different paging devices under the same beam to initiate paging to different paging devices (such as terminal devices), avoiding the reduction in paging capacity caused by all paging devices under the same beam initiating paging to the paging devices under that beam.

[0022] In one possible design, when the first parameter includes the identifier of the third communication device and the identifier of the terminal device, at least one third communication device includes N third communication devices, and at least one terminal device includes a first communication device; determining M second resources based on the first beam includes: determining M second resources based on the first beam, the identifier of the third communication device, and the identifier of the first communication device.

[0023] Based on this possible design, in addition to establishing the correspondence between different beams and the paging devices (or third communication devices) associated with the second communication device and different paging times (i.e., multiple second resources), it is also possible to further establish the correspondence between the identifier of the paging device (such as a terminal device), the identifier of the paging device (such as the third communication device), different beams, and different paging times. This allows different paging devices to paging according to different resources, and different paging devices under the same beam to initiate paging to different paging devices (such as terminal devices). This avoids the reduction in paging efficiency and capacity caused by all paging devices under the same beam occupying the same resources and all paging devices under the same beam initiating paging to the paging devices under that beam.

[0024] In one possible design, before receiving paging messages from N third communication devices based on M second resources corresponding to the first beam, the method further includes: receiving a second signal from a second communication device on the first resource, the second signal being used to wake up the first communication device, the second signal being carried on the second beam corresponding to the M second resources.

[0025] Based on this possible design, when determining the correspondence between a beam and a second resource, multiple beams can also correspond to the same second resource (e.g., both the first beam and the second beam correspond to the M second resources), providing another possible implementation method for realizing the first correspondence.

[0026] In one possible design, the area where the second and third communication devices are located includes one or more of the following: cell, tracking area, wireless alert area, registration area, or preset area.

[0027] In one possible design, before receiving a first signal from a second communication device on a first resource, the method further includes: receiving fourth indication information, the fourth indication information indicating the area where the second communication device is located; and before receiving paging messages from N third communication devices according to M second resources corresponding to a first beam, the method further includes: receiving fifth indication information, the fifth indication information indicating the area where the third communication device is located, the area where the second communication device is located being the same as the area where the third communication device is located.

[0028] Based on the two possible designs described above, it can be understood that when the wake-up signal WUS device and the paging device are different devices, the WUS device needs to complete the paging process together with its associated paging device. Therefore, during the paging process of the first communication device, a device with wake-up functionality (i.e., the second communication device) and its associated paging devices (i.e., N third communication devices) need to complete the paging process together. Thus, it can be defined that when the WUS device (such as the second communication device) and the paging device (such as the third communication device) are in the same area, the WUS device is considered to be associated with the paging device. This allows the first communication device to identify the second and third communication devices that are completing the paging process with it, thereby enabling paging of the first communication device from the network side.

[0029] Secondly, this application provides a paging method, which can be executed by a second communication device. Unless otherwise specified, the "second communication device" in this application can refer to a second communication equipment, a component within the second communication equipment (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the second communication equipment. The method includes: determining a first resource; transmitting a first signal on the first resource; the first signal being used to wake up a first communication device; the first signal being carried on a first beam of the second communication device; wherein the first beam corresponds to M second resources, the M second resources are used to determine a paging message carried on a third resource, and the first communication device and N third communication devices transmitting the paging message are located in the same area, where M and N are both integers greater than or equal to 1.

[0030] Based on the second aspect, the first beam of the second communication device used to send a wake-up signal (i.e., the first signal) is associated with the paging resources of the third communication device. In the paging process, N third communication devices send paging messages according to the second resources corresponding to the first beam of the second communication device, and the first communication device receives the paging messages according to the M second resources corresponding to the first beam. Compared to multiple third communication devices simultaneously sending paging messages according to all resources corresponding to the second communication device (e.g., resources corresponding to multiple beams), paging power consumption and paging resource consumption can be reduced, thereby increasing paging capacity.

[0031] In one possible design, the M second resources are the M resources corresponding to the identifier of the first beam in the first correspondence, and the first correspondence includes the correspondence between the identifier of at least one beam and at least one resource.

[0032] In one possible design, the method further includes: sending a second indication message, the second indication message indicating the first correspondence.

[0033] In one possible design, the first correspondence also includes the identification of at least one beam, at least one resource, and a correspondence between at least one first parameter, the first parameter including at least one of the following types of parameters: offset value, identification of the third communication device, and identification of the terminal device.

[0034] In one possible design, when the first parameter includes the identifier of the terminal device, at least one first parameter includes the identifier of at least one terminal device, the at least one terminal device includes a first communication device, and M second resources are determined based on the first beam and the identifier of the first communication device.

[0035] In one possible design, when the first parameter includes an offset value, at least one first parameter includes at least one offset value, and M second resources are based on the first beam and the first offset value, wherein at least one offset value includes the first offset value.

[0036] In one possible design, the method further includes sending a third indication message that indicates the first offset value.

[0037] In one possible design, when the first parameter includes the identifier of the third communication device, at least one third communication device includes N third communication devices, and M second resources are determined based on the first beam and the identifier of the third communication device.

[0038] In one possible design, when the first parameter includes the identifier of the third communication device and the identifier of the terminal device, at least one third communication device includes N third communication devices, at least one terminal device includes a first communication device, and M second resources are determined based on the first beam, the identifier of the third communication device, and the identifier of the first communication device.

[0039] In one possible design, before receiving paging messages from N third communication devices based on M second resources corresponding to the first beam, the method further includes: sending a second signal on the first resource, the second signal being used to wake up the first communication device or the fourth communication device, the second signal being carried on the second beam corresponding to the M second resources.

[0040] The technical effects of any design in the second aspect can be referenced from the technical effects of the corresponding design in the first aspect, and will not be elaborated here.

[0041] In conjunction with the first or second aspect, in one possible design, when M equals N, the M signals correspond one-to-one with the N third communication devices; when M is greater than N, at least one of the N third communication devices corresponds to multiple second resources among the M second resources.

[0042] In conjunction with the first or second aspect, in one possible design, when N is greater than 1, the N third communication devices include the second communication devices.

[0043] Based on this possible design, since the first communication device only needs to complete the paging process through two communication devices (i.e., a second communication device and a third communication device with different geographical locations) when N is greater than 1, that is, the paging method provided in this application is used only when N is greater than 1. When N equals 1, paging can be achieved without using the paging method provided in this application (such as using the paging method described in the current standard). Therefore, in this application, when N is greater than 1, the above-mentioned N third communication devices may also include the second communication device. In this case, the paging method provided in this application can be used to complete the paging.

[0044] Thirdly, embodiments of this application provide a communication device that can be applied to the first communication device described in the first aspect to achieve the functions performed by the first communication device. This communication device can be a first communication equipment, or a chip, chip system, or system-on-a-chip of the first communication equipment, etc. The communication device can execute the functions performed by the first communication device through hardware, or it can execute corresponding software through hardware. The hardware or software includes one or more modules corresponding to the above functions. For example, a transceiver module and a processing module. The transceiver module can independently complete the following transceiver operations, or it can cooperate with the processing module to complete the following transceiver operations; correspondingly, the processing module can independently complete the following processing operations, or it can cooperate with the transceiver module to complete the following processing operations, without limitation.

[0045] For example, the transceiver module is used to receive a first signal from a second communication device on a first resource. The first signal is used to wake up the first communication device and is carried on a first beam of the second communication device. The processing module is used to receive paging messages from N third communication devices according to M second resources corresponding to the first beam. The second and third communication devices are located in the same area, and M and N are both integers greater than or equal to 1.

[0046] Optionally, the transceiver module and processing module of the first communication device in the third aspect may also perform the corresponding functions in the first aspect or any possible design of the first aspect, as detailed in the method examples, and the beneficial effects that can be achieved can also be found in the foregoing related content.

The hardware or software includes one or more modules corresponding to the above functions. For example, a transceiver module and a processing module. The transceiver module can independently complete the following transceiver operations, or it can cooperate with the processing module to complete the following transceiver operations; correspondingly, the processing module can independently complete the following processing operations, or it can cooperate with the transceiver module to complete the following processing operations, without limitation.

[0048] For example, a processing module is used to determine a first resource; a transceiver module is used to send a first signal on the first resource, the first signal being used to wake up a first communication device, the first signal being carried on a first beam of a second communication device; wherein, the first beam corresponds to M second resources, the M second resources are used to determine a paging message carried on a third resource, the first communication device and N third communication devices that send the paging message are located in the same area, and M and N are both integers greater than or equal to 1.

[0049] Optionally, the transceiver module and processing module of the second communication device in the fourth aspect may also perform the corresponding functions in the second aspect or any possible design of the second aspect, as detailed in the method examples, and the beneficial effects that can be achieved can also be found in the foregoing related content.

[0077] To facilitate understanding of the technical solutions of the embodiments of this application, a brief introduction to the relevant technologies of this application is given below.

[0078] Paging Procedure: For terminal devices in an idle or inactive state, the network-side device sends downlink control information (DCI) on the physical downlink control channel (PDCCH) corresponding to the paging occasion (PO). The terminal can then perform blind detection on the PDCCH and receive the DCI. The DCI indicates the time-frequency resources of the physical downlink shared channel (PDSCH) and is carried on the PO. Furthermore, the network-side device can send a paging message on the time-frequency resources of this PDSCH; correspondingly, the terminal can receive the paging message on the time-frequency resources of this PDSCH. This process is called the paging procedure.

[0079] The paging message may contain the identifier (ID) of the paging terminal device. If the paging terminal contains the ID of the terminal device (i.e., the paging message contains the ID of the terminal device), the terminal device may initiate a random access procedure.

[0080] Understandably, before uplink and downlink interactions, the terminal device typically needs to receive a synchronization signal / physical broadcast channel block (SSB) from the network-side device to obtain synchronization and system messages. Therefore, the terminal device also needs to receive an SSB from the network-side device before initiating a random access procedure.

[0081] Specifically, the information format of the aforementioned DCI can be DCI1_0.

[0082] Wake-up signal (WUS): WUS was introduced in 3GPP Release 16 (Rel16 or R16). WUS is used to wake up terminal devices in a dormant state. Furthermore, WUS can also be used to initiate paging procedures. Specifically, the WUS message format can be DCI2_6.

[0083] For example, such as Figure 1As shown, WUS indicates that the terminal device should be woken up in the next discontinuous reception (DRX) cycle (e.g., DRX#1), enabling the terminal device to turn on the receiver (e.g., RF device) and enter the DRX active state during the duration of that DRX cycle, monitor the PDCCH, and receive the DCI carried on the PO. If no WUS is received from the network side or a sleep indication is received from the network side (e.g., WUS indicates sleep), the terminal device will remain in sleep mode in the next discontinuous reception (DRX) cycle (e.g., DRX#2).

[0084] Among them, the paging process initiated by WUS is as follows: Figure 2 As shown, the network-side device can send a WUS to the terminal device, which instructs the terminal device to wake up in the next DRX cycle. This allows the terminal device to turn on its receiver (e.g., RF device) and enter the DRX active state during the duration of that DRX cycle, monitoring the PDCCH to receive the DCI carried on the PO. Further, it receives a paging message on the time frequency of the PDSCH indicated by the DCI. If the paging message contains the terminal device's ID, the terminal device can initiate a random access procedure. Before initiating random access, the terminal device can also receive SSBs from the network-side device to obtain synchronization and system messages.

[0085] To further reduce the power consumption of WUS, 3GPP releases 18 and 19 introduced wake-up receiver / radio (WUR) to achieve low-power WUS (LP-WUS). LP-WUS is a working mechanism designed to support low-power devices (such as IoT devices, sensors, smart meters, etc.) and aims to quickly and reliably wake up low-power devices from long-term sleep states and enable them to communicate with the network. LP-WUS typically operates on low-frequency time-frequency resources; these resources can also be called LP-WUS occasions (LOs).

[0086] Under this operating mechanism, after receiving LP-WUS, the low-power device receives the DCI from the network-side device on the PDCCH corresponding to the appropriate PO. Specifically, there are several paging frames (PF) within a DRX cycle, and one PF corresponds to several POs. The DCI received by a terminal is carried on a specific PO within that DRX cycle. Therefore, upon receiving LP-WUS, the terminal device can calculate and determine the PO used to carry the DCI.

[0087] Furthermore, to improve the efficiency of terminal devices in determining the PO, a correspondence between LO and PO can be established based on the relative offset between them. This allows the terminal device to directly determine the PO based on the LO used to carry the LP-WUS after receiving it. Taking offset value #1 as an example, for instance... Figure 3 As shown, PO#1 can be obtained after offsetting LO#1 by offsetting value #1; similarly, PO#2 can be obtained after offsetting LO#2 by offsetting value #1; and PO#3 can be obtained after offsetting LO#3 by offsetting value #1.

[0088] As mentioned above, the paging process is based on the premise that WUS (or LP-WUS) and the paging message are output by the same device. Furthermore, in the current paging process, for a single terminal device, multiple network-side devices may simultaneously page it. The terminal device accesses (initiates random access) the network-side device that it receives the paging message from. If the terminal device receives paging messages from multiple network-side devices, it can choose to access one of them. For example, it can access the network-side device with the strongest signal quality. This easily leads to wasted paging resources and reduced paging capacity.

[0089] In one possible implementation, the WUS (or LP-WUS) and the paging message may be output by different devices; specifically, the device to which the WUS (or LP-WUS) belongs (i.e., the device that outputs the WUS or LP-WUS, hereinafter referred to as the WUS device) and the device to which the paging message belongs (or, in other words, the device used to output the paging message, hereinafter referred to as the paging device) are geographically different. In this case, the WUS device is associated with one or more paging devices (wherein, the one or more paging devices are in the same area as the WUS device), meaning that the WUS device can complete the paging process together with any one of the one or more paging devices in the same area. One possible method is that after the WUS device sends the LP-WUS to the terminal device at the LP-WUS time (i.e., LO), all paging devices associated with the WUS device execute the paging process at the paging time (i.e., PO) corresponding to that LP-WUS time (i.e., the DCI used to indicate the paging message is carried at the paging time). In other words, multiple paging devices may simultaneously page the terminal device, which can easily lead to increased paging power consumption, wasted paging resources, and reduced paging capacity.

[0090] In view of this, this application provides a paging method and apparatus, wherein a first beam of a second communication device for sending a wake-up signal (i.e., a first signal) is associated with paging resources of a third communication device. In the paging process, N third communication devices send paging messages according to the second resources corresponding to the first beam of the second communication device, and the first communication device receives the paging messages according to the M second resources corresponding to the first beam. Compared to sending paging messages simultaneously according to all resources corresponding to the second communication device (e.g., resources corresponding to multiple beams), this reduces paging power consumption and paging resource consumption, thereby increasing paging capacity.

[0091] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0092] The encoding method provided in this application can be used in any communication system, such as a 3GPP communication system, for example, a long term evolution (LTE) system, a fifth generation (5G) mobile communication system, a hybrid LTE and 5G network system, a new radio (NR) system, a vehicle-to-everything (V2X) system, a device-to-device (D2D) communication system, a machine-to-machine (M2M) communication system, an Internet of Things (IoT) system, a narrow band Internet of Things (NB-IoT) system, enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (URLLC), enhanced machine-type communication (eMTC), and various types of future communication systems. It can also be used for non-terrestrial communication networks. No restrictions are imposed on network (NTN) systems (such as satellite communication systems) and non-3GPP communication systems (such as open radio access networks (O-RAN or ORAN), cloud radio access networks (CRAN), wireless fidelity (WiFi) systems).

[0093] The following is based on Figure 4 Taking an example, the communication system provided in the embodiments of this application will be described. Figure 4 As shown, the communication system may include at least one WUS device, at least one paging device, and at least one paged device. The at least one WUS device and the at least one paging device include one or more sets of associated devices, each set of associated devices including one WUS device and at least one paging device (i.e., the one WUS device is associated with the at least one paging device). Furthermore, each set of associated devices can complete the paging process together with at least one paged device from the at least one paging device.

[0094] For example, the paging device and the WUS device can be network devices, and the paging device can be a terminal device.

[0095] The terminal device can be a device with wireless transceiver capabilities or a chip or chip system that can be installed on the device. It allows users to access the network and is used to provide voice and / or data connectivity to users. The terminal device can also be called user equipment (UE), subscriber unit, terminal, mobile station (MS), or mobile terminal (MT), etc.

[0096] For example, a terminal device can be a mobile phone, tablet computer, or computer with wireless transceiver capabilities. Terminal devices can also be user stations, mobile stations, remote stations, remote terminal devices, mobile terminal devices, user terminal devices, wireless communication devices, user agents, user devices, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices, processing devices connected to wireless modems, in-vehicle devices, wearable devices, terminal devices in the Internet of Things (IoT), home appliances, virtual reality (VR) terminals, augmented reality (AR) terminals, customer-premises equipment (CPE), light user equipment (Light UE), reduced capability user equipment (REDCAP UE), wireless terminals in industrial control, wireless terminals in autonomous driving, wireless terminals in telemedicine, wireless terminals in smart grids, wireless terminals in smart cities, and wireless terminals in smart homes. Wireless terminals in the home, vehicles with vehicle-to-everything (V2X) communication capabilities, intelligent connected vehicles, vehicle devices (such as vehicle devices, vehicle modules, vehicle chips, on-board units (OBU) or telematics boxes (T-BOX), etc.), drones with UAV to UAV (U2U) communication capabilities, terminal devices in future networks, or terminal devices in future evolved public land mobile networks (PLMNs) are not restricted.

[0097] The network device can be any device deployed in the access network capable of wireless communication with terminal devices. It can also be a chip or chip system that can be configured within such devices, a logical node or logical module, or a function implemented in software. Its main responsibilities include air interface-side wireless physical control, resource scheduling, wireless resource management, quality of service management, data compression and encryption, wireless access control, and mobility management. Specifically, the network device can be either a wired access device or a wireless access device.

[0098] For example, a network device can consist of one or more access network (AN) / radio access network (RAN) nodes. AN / RAN nodes can be various types of base stations, such as: satellite base stations, evolved Node Bs (gNBs), transmission reception points (TRPs), evolved Node Bs (eNBs), radio network controllers (RNCs), Node Bs (NBs), base station controllers (BSCs), base transceiver stations (BTSs), home base stations (e.g., home evolved Node Bs, or home Node Bs (HNBs), macro base stations, micro base stations, pico base stations, small cells, relay stations, balloon stations, drone stations, wireless backhaul nodes, baseband units (BBUs), or wireless fidelity (Wi-Fi) access points (APs), etc. It is understood that network devices can be terrestrial devices or non-terrestrial devices (such as satellites, drones, high-altitude communication equipment, etc.). Furthermore, in communication systems employing different wireless access technologies, the names of network devices with base station functions may differ, and this application does not impose any restrictions on this.

[0099] In another example, the network equipment may include a BBU and a remote radio unit (RRU). The BBU and RRU can be located in different places; for example, the RRU can be moved remotely to a high-traffic area, while the BBU is located in the central equipment room. The BBU and RRU can also be located in the same equipment room. The BBU and RRU can also be different components under the same rack.

[0100] In another example, the network device can be a device that includes centralized unit (CU) nodes, distributed unit (DU) nodes, or both CU and DU nodes. For instance, the network device can be logically divided into CUs and DUs, with some protocol layer functions centrally controlled by the CU, and the remaining partial or complete protocol layer functions distributed in the DU, which is centrally controlled by the CU. The CU and DU can be separate entities or included in the same network element, such as a BBU. Furthermore, the centralized unit (CU) can be further divided into a control plane (CU-CP) and a user plane (CU-UP).

[0101] In another example, the network device may also be a device that includes a radio unit (RU), or a device that includes a CU, a DU, and a RU. The RU may be included in a radio frequency device or radio frequency unit, such as an RRU, an active antenna unit (AAU), or a remote radio head (RRH).

[0102] It is understood that CU (or CU-CP and CU-UP), DU, or RU may have different names in different systems, but those skilled in the art will understand their meaning. For example, in an open radioaccess network (O-RAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through a software module, a hardware module, or a combination of software and hardware modules.

[0118] The following is combined Figure 4 The communication system shown refers to the following Figure 6 Taking the interaction between the first communication device, the second communication device, and the third communication device as an example, the paging method provided in this application embodiment is described; wherein, the first communication device can be Figure 4 In any of the paging devices in the communication system shown, the second communication device can be... Figure 4 In any WUS device in the communication system shown, the third communication device can be Figure 4 Any paging device in the communication system shown. Any one of the first, second, or third communication devices described in the following embodiments may include... Figure 5 The component shown.

[0119] Figure 6 This is a flowchart illustrating a paging method provided in an embodiment of this application, as shown below. Figure 6 As shown, the method may include the following steps:

[0120] S601, the second communication device sends a first signal on the first resource; correspondingly, the first communication device receives the first signal on the first resource.

[0121] The first signal is used to wake up the first communication device; and the first signal is carried on the first beam of the second communication device.

[0122] For example, since the first signal is transmitted by the second communication device on the first resource, and for a communication device, transmitting a signal on a resource means transmitting the signal on multiple beams. That is, the resource includes multiple sub-resources, and each sub-resource corresponds one-to-one with a multiple beam.

[0123] Therefore, for the first resource and the multiple beams of the second communication device, the first resource includes multiple sub-resources, each corresponding one-to-one with a beam of the second communication device. In this case, the second communication device sending a first signal to the first communication device via the first resource, with the first signal carried on the first beam of the second communication device, can be understood as the second communication device sending a signal via the first resource, which is then transmitted to different communication devices via multiple beams. Specifically, the signal transmitted via the first beam is the first signal, and the signal transmitted via the first beam can be transmitted to the first communication device.

[0124] For example, the content (e.g., sequence) of the signal transmitted on each beam of the second communication device is identical. This signal can be WUS, or LP-WUS, or other signals with wake-up functionality. Consequently, the first signal is also correspondingly WUS or LP-WUS, or other signals with wake-up functionality.

[0125] For example, the first resource can be an opportunity to carry a wake-up signal. For instance, the first resource is a LO, so the sub-resource corresponding to each beam can also be called a sub-LO, or it can also be called a low-power wake-up signal monitoring occasion (LP-WUS monitoring occasion, LMO), or it can be called any other possible name, which is not limited in this application.

[0126] For example, the second communication device can be a TRP. Since the second communication device is a WUS device, it can also be considered as a WUS TRP. The first communication device can be a terminal device (such as a UE).

[0127] S602, N third communication devices send paging messages to the first communication device according to M second resources corresponding to the first beam; the first communication device receives paging messages from the N third communication devices according to M second resources corresponding to the first beam.

[0128] The second and third communication devices are located in the same area, and M and N are both integers greater than or equal to 1.

[0129] For example, the third communication device can be a TRP. Since the second communication device is a paging device, the third communication device can also be considered as a paging TRP (or, it can also be called a main radio (MR) TRP).

[0130] The second and third communication devices being located in the same area can be understood as the second and third communication devices being associated; thus, the second and third communication devices can complete the paging process together. For example, as described above, when the WUS device and the paging device are different devices (e.g., the WUS device and the paging device are geographically different), typically a WUS device is associated with a paging device located in the same area; subsequently, the WUS device and the paging device located in the same area complete the paging process together.

[0131] In one possible implementation, the first communication device can determine whether the third communication device and the second communication device are located in the same area (or, whether they are associated) based on the area identification information of the third communication device and the area identification information of the second communication device. When the area identification information of the third communication device matches the area identification information of the second communication device, it indicates that the third communication device and the second communication device are associated, and the first communication device has the opportunity to access the network based on the paging process of the third communication device and the second communication device. When the area identification information of the third communication device does not match the area identification information of the second communication device, it indicates that the third communication device and the second communication device are not associated, and in this case, the third communication device and the second communication device cannot complete the paging process. For example, the matching of the area identification information of the third communication device and the area identification information of the second communication device can be that the area identification of the third communication device is the same as the area identification of the second communication device.

[0132] One possible implementation, before step S601, is as follows: Figure 7 As shown, the paging method also includes:

[0133] S600, the first communication device obtains the area identification information of the second communication device and the area identification information of the third communication device.

[0134] For example, the area identification information of the second communication device and the area identification information of the third communication device may be provided to the first communication device by the second communication device and / or the third communication device. For instance, the first communication device obtaining the area identification information of the second communication device and the area identification information of the third communication device may include: the first communication device receiving indication information #1 and indication information #2; wherein, indication information #1 indicates the area where the second communication device is located (e.g., indication information #1 indicates the area identification information of the second communication device), and indication information #2 indicates the area where the third communication device is located (e.g., indication information #2 indicates the area identification information of the third communication device).

[0135] In one example, indication information #1 and indication information #2 can be sent by the second communication device; that is, the third communication device can inform the second communication device of its area identification information, so that the second communication device can know the area identification information of the third communication device. Thus, the second communication device can inform the first communication device of its area identification information and the area identification information of the third communication device through indication information #1 and indication information #2.

[0136] For example, in this example, the third communication device can be any third communication device associated with the second communication device. That is, the second communication device can inform the first communication device of its own identification information and the identification information of the third communication devices associated with it, so that the first communication device can know all the third communication devices associated with the second communication device. Thus, in steps S601 to S602, the second communication device can perform a paging process with some of the third communication devices (such as N third communication devices) among all the third communication devices.

[0137] In another example, indication information #1 and indication information #2 can be sent by a third communication device; that is, the second communication device can inform the third communication device of its area identification information, so that the third communication device can know the area identification information of the second communication device. Thus, the third communication device can inform the first communication device of the area identification information of the second communication device and the area identification information of the third communication device through indication information #1 and indication information #2.

[0138] For example, in this example, the third communication device may include the following two implementations:

[0139] In one implementation, the third communication device can be any third communication device associated with the second communication device.

[0140] In this implementation, the second communication device can inform each of its associated third communication devices of its area identification information. Each third communication device can then obtain the area identification information of the second communication device and, in turn, inform the first communication device of its own area identification information and the area identification information of the second communication device. Each third communication device indicates the area identification information of the same second communication device, allowing the first communication device to know all the third communication devices associated with the second communication device. Therefore, in steps S601-S602, the second communication device can perform a paging process with some of the third communication devices (e.g., N third communication devices).

[0141] In another implementation, the third communication device can be one of the third communication devices associated with the second communication device.

[0142] In this implementation, the second communication device can inform the third communication device of its area identification information. Thus, the third communication device can inform the first communication device of its own area identification information, as well as the area identification information of the second communication device.

[0143] Furthermore, other third communication devices associated with the second communication device can each inform the first communication device of their own area identification information; alternatively, other third communication devices associated with the second communication device can also inform the first communication device of their own area identification information, thereby allowing the first communication device to also inform the first communication device of the area identification information of these other third communication devices. This enables the first communication device to know all the third communication devices associated with the second communication device, and thus, in steps S601 to S602, the second communication device can perform a paging process with some of these third communication devices (e.g., N third communication devices).

[0144] Combining the two examples above, instruction information #1 and instruction information #2 can be carried in the same signaling, or instruction information #1 and instruction information #2 can be the same instruction information. Alternatively, instruction information #1 and instruction information #2 can also be carried in different signaling. This application does not impose any restrictions.

[0145] In another example, indication information #1 can be sent by the second communication device, and indication information #2 can be sent by the third communication device. That is, the second communication device can inform the first communication device of its own area identification information through indication information #1, and the third communication device can inform the first communication device of its own area identification information through indication information #2.

[0146] For example, in this example, the third communication device can be any third communication device associated with the second communication device. That is, the identification information of each third communication device associated with the second communication device can be communicated to the first communication device through indication information #2, thereby the first communication device can know all the third communication devices associated with the second communication device after receiving indication information #1. Thus, in steps S601 to S602, the second communication device can perform a paging process with some of the third communication devices (such as N third communication devices).

[0147] Based on the three examples above, the aforementioned instruction information #1 may also have other names, such as fourth instruction information, area instruction information, etc.; similarly, instruction information #2 may also have other names, such as fifth instruction information, area instruction information, etc.; this application does not impose any restrictions.

[0148] In one possible implementation, step S600 can be performed when the first communication device is in a connected state (such as RRC-CONNECTED) or a disconnected state (such as RRC-IDLE, RRC-INACTIVE, or RRC-IDLE).

[0149] For example, typically, a communication device can access the network through a paging process to transition from a non-connected state to a connected state. That is, during steps S601-S602, the first communication device is in a non-connected state. Therefore, during step S600, if the first communication device is in a connected state, it means that before step S601, when the first communication device was in a connected state, it could obtain the area identification information of the second and / or third communication devices from the second and / or third communication devices (i.e., execute step S600). Thus, when the first communication device is in a non-connected state, it can access the network by performing a paging process through the associated second and third communication devices (i.e., execute steps S602-S602); if the first communication device is in a non-connected state, it means that when the first communication device is in a non-connected state, it first obtains the area identification information of the second and / or third communication devices from the second and / or third communication devices (i.e., execute step S600). Then, a paging process is performed through the associated second and third communication devices to access the network (i.e., steps S602 to S602 are executed).

[0150] For ease of description, the following embodiments use the example of "indication information #1 being sent by the second communication device and indication information #2 being sent by the third communication device" to illustrate the implementation of the area (i.e., the area where the second communication device is located and / or the area where the third communication device is located) described in this application; this will be explained uniformly here and will not be repeated.

[0151] In one possible implementation, the area in this application includes one or more of the following: cell, tracking area, wireless alert area, registration area, or preset area.

[0152] In one possible implementation, the area described in this application can be a cell; that is, the area identification information in step S600 is a cell identifier (such as a cell ID). In other words, the second communication device and the third communication device are in the same cell.

[0153] It is understandable that the cell identifier is usually carried in the SSB; therefore, indication information #1 and indication information #2 can be carried in the SSB.

[0154] In another possible implementation, the area described in this application can be a preset area; that is, the area identification information in step S600 is the identification information of a preset area. In other words, the second communication device and the third communication device are located in the same preset area.

[0155] For example, in this possible implementation, the area identification information can be statically indicated, that is, indication information #1 and indication information #2 can be carried in static signaling, such as SSB, system information block 1 (SIB1), or system information block 2 (SIB2), etc. Alternatively, the area identification information can also be dynamically indicated, that is, indication information #1 and indication information #2 can be carried in dynamic signaling, such as RRC signaling, medium access control-control element (MAC-CE) signaling, and DCI.

[0156] In another possible implementation, the area described in this application may be any one of a tracking area (TA), a radio-based notification area (RNA), or a registration area (RA).

[0157] Specifically, when the region described in this application is a TA, the region identification information in step S600 is a TA identifier (such as TA ID). That is, the second communication device and the third communication device are in the same TA. When the region described in this application is an RNA, the region identification information in step S600 is an RNA identifier (such as RAN ID). That is, the second communication device and the third communication device are in the same RNA. When the region described in this application is a RA, the region identification information in step S600 is an RA identifier (RA ID). That is, the second communication device and the third communication device are in the same RA.

[0158] It is understandable that the TA identifier is usually carried in SIB1; therefore, indication information #1 and indication information #2 can also be carried in SIB1. The RNA identifier and RA identifier are usually configured by any of RRC signaling, MAC-CE signaling, or higher-level signaling (including but not limited to non-access stratum (NAS) signaling). Therefore, indication information #1 and indication information #2 can also be carried in any of RRC signaling, MAC-CE signaling, or higher-level signaling.

[0159] Combining the above possible implementation methods, for example, such as Figure 8 As shown, step S602 can be replaced by the following steps S6021 to S6023:

[0160] S6021. The first communication device determines M second resources based on the first beam.

[0161] Typically, among multiple third communication devices associated with a second communication device, the signal coverage area of ​​the third communication device is smaller than that of the second communication device; furthermore, the third communication device is located within the signal coverage area of ​​the second communication device. For example, such as Figure 9 As shown, the solid line area represents the signal coverage range of the second communication device, and the dashed line area represents the signal coverage range of each of the third communication devices (i.e., third communication device #1 to third communication device #4).

[0162] Furthermore, among the plurality of third communication devices associated with the second communication device, each third communication device corresponds to at least one second resource. In this case, the first resource can also be considered to correspond to a plurality of second resources. The plurality of resources includes at least one second resource corresponding to each third communication device.

[0163] As mentioned above, the first resource includes multiple sub-resources, each corresponding one-to-one with a beam of the second communication device. Therefore, the correspondence between the first resource and multiple second resources can also be understood as multiple beams corresponding to multiple second resources. Each beam corresponds to one or more of the multiple second resources. In other words, according to the beams of the second communication device, a correspondence is established between different beams and different second resources, such that each beam corresponds to one or more of the multiple second resources. For example, the first beam corresponds to M second resources.

[0164] Specifically, since each third communication device corresponds to at least one second resource, a correspondence can be established between different beams and different third communication devices among the multiple third communication devices, based on the beams of the second communication devices, so that each beam corresponds to at least one third communication device among the multiple third communication devices. Furthermore, the second resource corresponding to at least one third communication device corresponding to each beam is determined as the second resource corresponding to that beam.

[0165] For example, a correspondence can be established between different beams and different third communication devices among multiple third communication devices based on the beam direction of the second communication device and the geographical location of the third communication device. A third communication device located in a certain beam direction is identified as the third communication device corresponding to that beam direction. In this case, the second resource corresponding to that third communication device is the second resource corresponding to that beam. Specifically, the third communication devices corresponding to the first beam are the N third communication devices in step S602 above, and the second resources corresponding to the first beam are the M second resources in step S602 above. That is, the first communication device can obtain information about N third communication devices and M second resources based on the first beam.

[0166] Optionally, when M equals N, there is a one-to-one correspondence between the M second resources and the N third communication devices; that is, each third communication device corresponds to one second resource. When M is greater than N, at least one of the N third communication devices corresponds to multiple second resources among the M second resources; or, in other words, among the N third communication devices, there exists at least one third communication device whose individual third devices correspond to multiple second resources.

[0167] It should be noted that the above examples all illustrate the implementation of N third communication devices by taking the example that the second and third communication devices are geographically different. In fact, multiple third communication devices associated with the second communication device can also include the second communication device. Therefore, the N third communication devices described in this application can also include the second communication device. In this case, only when N is greater than 1 will the first communication device need to complete the paging process through two communication devices (i.e., the second and third communication devices with different geographical locations). That is to say, the paging method provided in this application is used only when N is greater than 1. When N is equal to 1, paging can be achieved without using the paging method provided in this application (such as using the paging method described in the current standard). Therefore, in this application, when N is greater than 1, the above-mentioned N third communication devices can also include the second communication device. At this time, the paging method provided in this application can be used to complete the paging (i.e., execute the above steps S601 to S602).

[0168] S6022, N third communication devices send M first indication messages to the first communication device on M second resources; correspondingly, the first communication device receives M first indication messages from the N third communication devices on the M second resources.

[0169] Among them, M first indication information correspond one-to-one with M second resources; the first indication information indicates the third resource used to carry paging messages.

[0170] For example, since the M first indication messages correspond one-to-one with the M second resources, step S6022 can also be understood as: the N third communication devices respectively send the first indication messages to the first communication device on their corresponding second resources; correspondingly, the first communication device receives the first indication messages from the third communication device on the second resources corresponding to each of the N third communication devices.

[0171] For example, since the first indication information indicates a third resource for carrying a paging message, meaning the first communication device can obtain one third resource on each of the M second resources, the first communication device obtains a total of M third resources in step S6022. Each of the M third resources corresponds one-to-one with one of the M second resources.

[0172] For example, the second resource can be the timing of carrying "information indicating a resource (such as a third resource) for carrying a paging message (i.e., first indication information)", for example, the second resource can be a PO. Thus, the M second resources corresponding to the first beam can also be referred to as: the M POs corresponding to the second beam.

[0173] Optionally, the first instruction information can be carried in the DCI.

[0174] For example, the third resource can be the time-frequency resource of the PDSCH, or in other words, the third resource is the time-frequency resource of the PDSCH used to carry paging messages.

[0175] S6023, N third communication devices send paging messages to the first communication device according to M first instruction information; correspondingly, the first communication device receives paging messages from the N third communication devices according to the first instruction information.

[0176] For example, each of the N third communication devices sends a paging message on the third resource it indicates; correspondingly, the first communication device receives the paging message from the third communication device on the third resource indicated by the third communication device.

[0177] For example, when the paging message sent by the third communication device contains the ID of the first communication device, the first communication device can initiate random access to the third communication device and thus access the network.

[0178] This application provides a paging method and apparatus, wherein a first beam of a second communication device for sending a wake-up signal (i.e., a first signal) is associated with paging resources of a third communication device. In the paging process, N third communication devices send paging messages according to the second resources corresponding to the first beam of the second communication device, and the first communication device receives the paging messages according to the M second resources corresponding to the first beam. Compared to sending paging messages simultaneously according to all resources corresponding to the second communication device (e.g., resources corresponding to multiple beams), this method reduces paging power consumption and paging resource consumption, thereby increasing paging capacity.

[0179] The above is a general description of the paging method provided in this application. The following is a detailed description of the "M second resources" involved in the above embodiments.

[0180] Optionally, the M second resources are the M resources corresponding to the identifier of the first beam in the first correspondence relationship. The first correspondence relationship includes the correspondence between the identifier of at least one beam and at least one resource. That is, the correspondence between the identifier of at least one beam and at least one resource (i.e., the first correspondence relationship) can be pre-configured; thus, in step S6021, the first communication device can determine the M second resources from the first correspondence relationship according to the first correspondence relationship.

[0181] For example, in the first correspondence, the correspondence between beams and resources can include at least one of a one-to-one correspondence, a many-to-one correspondence, or a one-to-many correspondence. Specifically, a one-to-one correspondence between beams and resources means that the identifier of at least one beam corresponds to at least one resource. For example, at least one beam includes beam #1 and beam #2, and at least one resource includes resource #1 and resource #2; wherein beam #1 corresponds to resource #1, and beam #2 corresponds to resource #2.

[0182] The correspondence between beams and resources is "many-to-one," meaning that multiple beams correspond to the same resource. For example, at least one beam includes beams #1 to #5, and at least one resource includes resource #1 and resource #2; wherein beams #1 and #2 both correspond to resource #1, and beams #3 to #5 all correspond to resource #2.

[0183] The correspondence between beams and resources is "one-to-many," meaning that one beam corresponds to multiple resources. For example, at least one beam includes beam #1 and beam #2, and at least one resource includes resources #1 to #5; where beam #1 corresponds to resources #1 to #2, and beam #2 corresponds to resources #3 to #5.

[0184] Optionally, the first correspondence can be predefined by a protocol. Alternatively, it can be pre-agreed upon among the first communication device, the second communication device, and the third communication device; for example, the first correspondence can be pre-determined by the first communication device and communicated to the second and third communication devices, or the first correspondence can be pre-determined by the second communication device and communicated to the first and third communication devices, or the first correspondence can be pre-determined by the third communication device and communicated to the first and second communication devices.

[0185] For example, when the first correspondence is predetermined by the second or third communication device and communicated to the first communication device, the second or third communication device can execute the procedure before step S602; that is, as shown in the example... Figure 10 As shown, before step S602, the paging method may further include step S603 or step S604:

[0186] S603, the second communication device sends second instruction information to the first communication device; correspondingly, the first communication device receives the second instruction information from the second communication device. The second instruction information indicates the first correspondence.

[0187] S604, the third communication device sends second instruction information to the first communication device; correspondingly, the first communication device receives the second instruction information from the third communication device. The second instruction information indicates the first correspondence.

[0188] For example, the third communication device in step S604 can be any one of a plurality of third communication devices associated with the second communication device.

[0189] Specifically, the second instruction information can be carried in any of the following: SSB, RRC signaling, MAC-CE signaling, or DCI.

[0190] For example, regarding different implementations of the correspondence between beams and resources in the first correspondence, the first correspondence can be implemented based on the following two scenarios:

[0191] Scenario 1: The correspondence between beams and resources in the first correspondence is either a one-to-one or many-to-one relationship. In this scenario, the first correspondence can include the following two possible implementations:

[0192] In one possible implementation, the first correspondence includes a correspondence between two types of parameters: beam identifiers and resources. That is, the first correspondence includes a correspondence between at least one beam identifier and at least one resource. Therefore, the first communication device can determine M second resources from the first correspondence based on the identifier of the first beam.

[0193] For example, the SSB issued by the second communication device usually carries the identifier of its beam (i.e., beam ID, or beam index), so that the first communication device can know the identifier of the first beam when the first beam receives the first signal; and thus determine M second resources based on the identifier of the first beam.

[0194] Alternatively, the beam identifier can be determined based on the number of bits of the synchronization signal sent by the second communication device; for example, different numbers of bits of the synchronization signal are pre-configured to correspond to different beams of the second communication device, so that when the first communication device receives the synchronization signal, it can know the identifier of the beam (i.e., the first beam) used to carry the synchronization signal according to the synchronization signal, and then, when the first signal is received on the beam, it can determine M second resources based on the identifier of the first beam.

[0195] Alternatively, based on the identifier of the second communication device, the first resource can be pre-divided into at least one sub-resource, with each sub-resource corresponding to a beam; and a correspondence between the identifiers of the at least one sub-resource and the at least one beam can be configured for the first communication device. Thus, the beam corresponding to the sub-resource on which the first communication device receives the first signal is the first beam. For example, taking a first resource comprising 16 orthogonal frequency division multiplexing (OFDM) symbols (i.e., OFDM#0 to OFDM#15) and a second communication device comprising 8 beams (i.e., beams #0 to #7), each pair of OFDM symbols can correspond to one beam; that is, OFDM symbols #0 to #1 correspond to beam #0, OFDM symbols #2 to #3 correspond to beam #1, and so on, with OFDM symbols #14 to #15 corresponding to beam #7. Therefore, when the first communication device receives the first signal on the OFDM symbol corresponding to the first beam, it can determine the identifier of the first beam.

[0196] As mentioned above, there are several Power Factors (PFs) within a DRX cycle, and each PF corresponds to several Resource Objects (POs). Therefore, a second resource with the same function as a PO can also be considered a resource within a PF. Thus, when determining a second resource, it is also necessary to determine which PF it belongs to in order to identify a unique second resource. Therefore, the first correspondence can include at least the following two examples:

[0197] In one example, the first correspondence can be characterized by a formula. For example, the first correspondence may include the contents shown in relation (1) and relation (2):

[0198] The second resource number = the beam identifier mod NS relationship (1);

[0199] PF number = beam identifier mod NP relationship (2);

[0200] Among them, the number of PFs (NP) within the DRX cycle and the number of POs (NS) within a PF in the above relations (1) and (2) can be called paging parameters. NP represents the number of PFs within the DRX cycle T; NS represents the number of resources (such as POs) in a PF. NP and NS can be carried in SIB1. The DRX cycle can also be called the paging cycle. The number of the second resource (or the sequence number of the second resource) represents the number of the second resource among the NS resources in a PF; the beam identifier represents the beam carrying the information (such as the first signal) for the user to wake up the first communication device; "mod" represents the remainder obtained after dividing the two numbers before and after mod; the number of the PF (or the index of the PF) represents the number of the PF where the second resource is located among the NP PFs.

[0201] Alternatively, the PF where the second resource is located can also be represented by the PF's system frame number (SFN); in this case, relation (2) can be replaced by relation (3):

[0202] (SFN+PF_offset)mod T=(T div NS)*(beam identifier mod NP) relation(3);

[0203] Among them, PF_offset, DRX period T, NP, and NS in the above relationship (3) can be called paging parameters. PF_offset is the offset value used to determine PF. PF_offset can be predefined by the protocol or determined by the network-side device (such as the second or third communication device) and configured to the first communication device. "*" means multiplication calculation. "div" means division calculation.

[0204] It should be understood that in the embodiments of this application, the DRX period T, the number of PFs NP within the DRX period, and the number of POs NS within a PF can be dynamically configured as needed or predefined by the protocol, and are not limited.

[0205] In another example, the first correspondence can be represented by a table.

[0206] In the first correspondence under this example, the correspondence between each beam and the number of the second resource can satisfy relation (1), and the correspondence between each beam and the number of the PF can satisfy relation (1).

[0207] Specifically, taking N equal to 1 (i.e., each beam corresponds to one second resource) as an example, the first correspondence can include the content shown in representation 1:

[0208] Table 1

[0209] Beam identification PF number Second resource number 0 0 2 1 1 1 2 3 4 … … …

[0210] For example, the correspondence between each beam and the second resource in Table 1 can be as follows: Figure 11 As shown, when the identifier of the first beam is 0 (i.e. Figure 11 When the first beam is #0, the second resource corresponding to the first beam is resource number 2 in the PF with SFN of 0 (i.e., Figure 11 The second resource in the middle (#2); similarly, when the identifier of the first beam is 1 (i.e. Figure 11 When the first beam is #1, the second resource corresponding to the first beam is resource number 1 in PF number 1 (i.e., ... Figure 11 The second resource #1); when the identifier of the first beam is 2 (i.e. Figure 11 When the first beam is #2, the second resource corresponding to the first beam is resource number 4 in PF number 3 (i.e., Figure 11 The second resource in #4).

[0211] It should be noted that Table 1 above describes the implementation of the first correspondence relationship by taking the example of each beam corresponding to one second resource. In fact, each beam can also correspond to multiple second resources (i.e., N is greater than 1). In this case, the identifier of each beam in the first correspondence relationship corresponds to multiple second resources, and each second resource corresponds to a PF number. Among the multiple second resources corresponding to the identifier of each beam, the PF numbers corresponding to any two second resources can be the same or different, which is not restricted in this application.

[0212] Alternatively, in this example, the correspondence between the beam, SFN, and second resource number can be represented by a table (e.g., replacing the PF number in Table 1 above with the SFN), where the correspondence between the SFN and the beam satisfies relation (3). That is, the first correspondence includes the correspondence between multiple beams, multiple SFNs, and multiple second resources. In this case, the implementation of the first correspondence is similar to that in Table 1, and the relevant description in Table 1 can be found therein, which will not be repeated here.

[0213] In another possible implementation, the first correspondence includes the correspondence between three types of parameters: beam identifier, first parameter, and resource. That is, the first correspondence includes the correspondence between at least one beam identifier, at least one first parameter, and at least one resource. Therefore, the first communication device can determine M second resources based on the first beam identifier and the first parameter within the first correspondence.

[0214] The first parameter may include at least one of the following types of parameters: offset value, identifier of the third communication device, and identifier of the terminal device. For ease of description, the implementation of the first correspondence will be described below using the offset value, the identifier of the third communication device, and the identifier of the terminal device as examples.

[0215] For example, in the first correspondence, the correspondence between (beam + first parameter) and resources can include at least one-to-one correspondence and / or one-to-many correspondence. Specifically, a one-to-one correspondence between (beam + first parameter) and resources means that one beam and one first parameter correspond to one of at least one resources. For example, at least one beam includes beam #1 and beam #2, at least one first parameter includes first parameter #1 and first parameter #2, and at least one resource includes resources #1 to resources #4; wherein, beam #1 corresponds to resource #1 with first parameter #1, beam #1 corresponds to resource #2 with first parameter #2, beam #2 corresponds to resource #3 with first parameter #1, and beam #2 corresponds to resource #4 with first parameter #2.

[0216] The correspondence between (beam + first parameter) and resources is "one-to-many," meaning that one (beam + first parameter) corresponds to multiple resources. For example, at least one beam includes beam #1 and beam #2, at least one first parameter includes first parameter #1 and first parameter #2, and at least one resource includes resources #1 to #10; wherein, beam #1 and first parameter #1 correspond to resources #1 to #2, beam #2 and first parameter #1 correspond to resources #3 to #5, beam #1 and first parameter #2 correspond to resources #6 to #7, and beam #2 and first parameter #2 correspond to resources #8 to #10.

[0217] Specifically, in this possible implementation, the method for obtaining the beam identifier (such as the identifier of the first beam) can be found in the relevant description in "One Possible Implementation" above, and will not be repeated here.

[0218] In one example, the first parameter includes the identifier of the terminal device; that is, the first correspondence includes the identifier of at least one beam, the identifier of at least one terminal device, and the correspondence between at least one resource. The at least one terminal device includes a first communication device.

[0219] For example, in this example, when the number of identifiers of at least one terminal device is multiple, the identifiers of any two terminal devices among the multiple terminal device identifiers may be the same or different, and this application does not impose any restrictions.

[0220] Optionally, in this example, step S6021 can be replaced by: the first communication device determining M second resources based on the first beam and the identifier of the first communication device.

[0221] For example, after learning the identifier of the first beam, the first communication device can determine M second resources in the first correspondence relationship based on the identifier of the first beam and its own identifier. At this time, the M second resources are the resources corresponding to the identifier of the first beam and the identifier of the first communication device in the first correspondence relationship.

[0222] As mentioned above, when determining the second resource, it is also necessary to determine which PF (Power Processing Unit) the second resource belongs to in order to identify a unique second resource. Therefore, in addition to including the identifier of the second resource itself, the first correspondence must also indicate the PF to which the second resource belongs. Specifically, the first correspondence can be represented by at least a formula or a table. Taking the first correspondence represented by a formula as an example, the first correspondence can include the content shown in relation (4-1) and relation (5-1), or the content shown in relation (4-1) and relation (5-2), or the content shown in relation (4-2) and relation (5-1):

[0223] The second resource number = (beam identifier + terminal device identifier) ​​mod NS relationship (4-1);

[0224] The second resource number = the beam identifier mod NS relationship (4-2);

[0225] PF number = (beam identifier + terminal device identifier) ​​mod NP relationship (5-1);

[0226] PF number = beam identifier mod NP relationship (5-2);

[0227] The identifier of the terminal device refers to the identifier of the paged device (or, in other words, the communication device that receives the first signal, such as the first communication device).

[0228] For example, the value of the terminal device's identifier (i.e., UE_ID) can be the terminal device's 5G-S-temporary mobile subscriber identity (5G-S-TMSI) mod 1024.

[0229] Alternatively, the PF where the second resource is located can also be represented by the SFN of the PF; in this case, relation (5-1) can be replaced by relation (6-1), and relation (5-2) can be replaced by relation (6-2):

[0230] (SFN+PF_offset)mod T=(T div NS)*((beam identifier+UE_ID)mod NP) relation (6-1);

[0231] (SFN+PF_offset)mod T=(T div NS)*(beam identifier mod NP) relationship (6-2);

[0232] Wherein, UE_ID represents the identifier of the terminal device.

[0233] Based on this example, in addition to establishing the correspondence between different POs (i.e., multiple second resources) of the paging device (or third communication device) associated with different beams and the second communication device, it is also possible to further establish the identification of different paging devices (such as terminal devices) and the correspondence between different beams and different POs, so that different paging devices can paging according to different resources, avoiding the reduction in paging efficiency caused by all paging devices under the same beam occupying the same resources.

[0234] In another example, the first parameter includes an offset value, meaning the first correspondence includes an identifier for at least one beam, at least one offset value, and a correspondence between at least one resource. For example, the offset value in this example can be understood as the offset value of the PO.

[0235] For example, in this instance, when there are multiple offset values, any two offset values ​​among the multiple offset values ​​may be the same or different, and this application does not limit this.

[0236] Optionally, in this example, step S6021 can be replaced by: the first communication device determining M second resources based on the first beam and the first offset value; wherein at least one offset value includes the first offset value.

[0237] For example, the offset value described in this application is less than or equal to the number of resources contained in a DRX cycle. For instance, if a DRX cycle contains NS*NP resources, the offset value can be any value among 0, 1, 2, ..., NS*NP-1.

[0238] Optionally, the offset value can be predefined by a protocol. Alternatively, it can be pre-agreed between the first communication device and the second or third communication device; for example, the offset value can be determined by the second communication device and communicated to the first communication device, and the first correspondence can be pre-determined by the third communication device and communicated to the first communication device.

[0239] Optionally, if the offset value is predetermined by the second or third communication device and communicated to the first communication device, the second or third communication device can execute the procedure before step S602; that is, if... Figure 12 As shown, before step S602, the paging method may further include step S605 or step S606:

[0240] S605, the second communication device sends a third indication message to the first communication device; correspondingly, the first communication device receives the third indication message from the second communication device. The third indication message indicates an offset value. For example, the third indication message indicates a first offset value.

[0241] For example, the second communication device may consider having a large interval between the second resources of the third communication device in different beam directions, providing the first communication device with more options in the process of establishing mobility relationships, and also improving the flexibility of the second resource configuration.

[0242] For example, the second communication device can set different offset values ​​for different third communication devices in different beam directions based on its beam direction; in this case, it can also be considered that in step S605, the second communication device sends multiple third indication messages to the first communication device. Among them, the multiple third indication messages correspond one-to-one with N beams. Alternatively, the second communication device can determine the size of the interval (e.g., time domain interval) between the second resources (e.g., the second resources determined based on relations (1) and (2)) of the third communication devices in different beam directions determined only by the beam, and set offset values ​​for the second resources with intervals less than the first threshold. The number of first indication messages sent by the second communication device is less than or equal to N.

[0243] S606, the third communication device sends third indication information to the first communication device; correspondingly, the first communication device receives the third indication information from the third communication device. The third indication information indicates an offset value. For example, the third indication information indicates a first offset value.

[0244] For example, each of the N third communication devices can execute step S606 to make a large interval (e.g., the interval is greater than or equal to a first threshold) between the second resources of the third communication devices in different beam directions determined by the first communication device based on the offset value and the beam identifier, thereby providing the first communication device with more options in the process of making mobility relationships and improving the flexibility of the second resource configuration.

[0245] Alternatively, each third communication device may determine its second resource based on the beam (e.g., the second resource determined based on relationship (1) and relationship (2); and then determine the size of the interval (e.g., time-domain interval) between its second resource and those of other third communication devices in the beam direction. When the interval is less than a first threshold, an offset value may be considered (i.e., step S606 is executed). This ensures that the second resource of the third communication device determined based on the third indication information can have an interval greater than or equal to the first threshold between its second resource and those of other third communication devices. This provides the first communication device with more options during the mobility relationship process. Furthermore, the offset value can be flexibly determined based on the network side's requirements to improve the flexibility of the second resource configuration.

[0246] Specifically, the third instruction information can be carried in any of the following: system information block (SIB), RRC signaling, MAC-CE signaling, or DCI.

[0247] Optionally, after obtaining the identifier and first offset value of the first beam, the first communication device can determine M second resources in the first correspondence relationship based on the identifier and first offset value of the first beam. In this case, the M second resources are the resources corresponding to the identifier and first offset value of the first beam in the first correspondence relationship.

[0248] As mentioned above, when determining the second resource, it is also necessary to determine which PF (Power Processing Unit) the second resource belongs to in order to identify a unique second resource. Therefore, in addition to including the identifier of the second resource itself, the first correspondence must also indicate the PF to which the second resource belongs. Specifically, the first correspondence can be represented by at least a formula or a table. Taking the first correspondence represented by a formula as an example, the first correspondence can include the content shown in relation (7-1) and relation (8-1), or the content shown in relation (7-1) and relation (8-2), or the content shown in relation (7-2) and relation (8-1):

[0249] The second resource number = (beam identifier + offset value) mod NS relationship (7-1);

[0250] The second resource number = the beam identifier mod NS relationship (7-2);

[0251] PF number = (beam identifier + offset value) mod NP relationship (8-1);

[0252] The PF number = beam identifier mod NP relationship (8-2);

[0253] The offset value represents the offset value of the second resource (i.e., PO) corresponding to the beam direction (such as the first offset value corresponding to the first beam).

[0254] Alternatively, the PF where the second resource is located can also be represented by the SFN of the PF; in this case, relation (8-1) can be replaced by relation (9-1), and relation (8-2) can be replaced by relation (9-2):

[0255] (SFN+PF_offset)mod T=(T div NS)*((beam identifier+offset value)mod NP) relation (9-1);

[0256] (SFN+PF_offset)mod T=(T div NS)*(beam identifier mod NP) relationship (9-2).

[0257] It is understood that the first correspondence shown in the two examples above can also be replaced by a table representation. The implementation is similar to the implementation of replacing relation (1) to relation (2) with the contents shown in Table 1 in the above embodiments. For details, please refer to the relevant description in the above embodiments, which will not be repeated here.

[0258] In another example, the first parameter includes the identifier of the third communication device, that is, the first correspondence includes the identifier of at least one beam, the identifier of at least one third communication device, and the correspondence between at least one resource. The at least one third communication device includes the N third communication devices described in step S602.

[0259] Optionally, in this example, step S6021 can be replaced by: the first communication device determining M second resources based on the first beam and the identifiers of N third communication devices.

[0260] For example, after learning the identifier of the first beam and the identifiers of N third communication devices, the first communication device can determine M second resources in the first correspondence relationship based on the identifier of the first beam and the identifiers of the N third communication devices. At this time, the M second resources are the resources corresponding to the identifier of the first beam and the identifiers of the N third communication devices in the first correspondence relationship.

[0261] As mentioned above, when identifying a second resource, it is also necessary to determine which PF (Power Processing Unit) the second resource belongs to in order to identify a unique second resource. Therefore, the first correspondence, in addition to including the identifier of the second resource itself, must also indicate the PF to which the second resource belongs. Specifically, the first correspondence can be represented by at least a formula or a table. Taking the representation of the first correspondence by a table as an example, the first correspondence can include the contents shown in Table 2:

[0262] Table 2

[0263] Identification of the third communication device PF number Second resource number Third communication device #1 Beam identifier modNS 0 Third communication device #2 Beam identifier modNS 2 … … …

[0264] Table 3

[0265] Identification of the third communication device PF number Second resource number Third communication device #1 Beam identifier modNS Beam identifier modNP Third communication device #2 Beam identifier modNS Beam identifier modNP … … …

[0266] Based on the first correspondence shown in Table 2 above, each third communication device corresponds to a PF number; however, since the second resource described in this scheme describes the resource within the DRX period, when the PF numbers corresponding to some third communication devices in Table 2 above do not belong to the DRX period, that is, only the PF numbers corresponding to the N third communication devices mentioned in step S602 belong to the DRX period.

[0267] Alternatively, the PF number in Table 2 and / or Table 3 can be replaced with SFN, in which case the relationship between SFN and beam identifier satisfies (3).

[0268] For example, the identifier of the third communication device includes, but is not limited to, any one of the following: the cell ID of the third communication device, the local cell ID of the third communication device, and the public land mobile network (PLMN) code of the third communication device.

[0269] For example, the identifier of the third communication device may be carried in any of the following: SSB, SIB, RRC signaling, MAC-CE signaling, or DCI.

[0270] Based on this example, in addition to establishing different POs (i.e., multiple second resources) for paging devices (or third communication devices) associated with the second communication device using different beams, it is also possible to further establish the identifiers of different paging devices (such as the third communication device) and the correspondence between different beams and different POs. This allows different paging devices under the same beam to initiate paging to different paging devices (such as terminal devices), avoiding a reduction in paging capacity caused by all paging devices under the same beam initiating paging to the paging devices under that beam.

[0271] The three examples described above can also be used in combination. For instance, the first parameter may include the identifier of the third communication device and the identifier of the terminal device. In this case, the first correspondence includes the identifier of at least one beam, the identifier of at least one terminal device, the identifier of at least one third communication device, and the correspondence between at least one resource. That is, the first communication device can determine M second resources based on the identifier of the first beam, the identifier of the third communication device, and the identifier of the first communication device in the first correspondence. In this case, the implementation of the correspondence between the three parameters "beam + identifier of the terminal device + identifier of the third communication device" and the resources in the first correspondence is similar to the implementation of the correspondence between the two parameters "beam + first parameter" and the resources described in the above embodiments. For details, please refer to the relevant descriptions in the above embodiments, which will not be repeated here.

[0272] Alternatively, the first parameter may include the identifier and offset value of the third communication device. In this case, the first correspondence includes the identifier of at least one beam, at least one offset value, the identifier of at least one third communication device, and the correspondence between at least one resource. That is, the first communication device can determine M second resources based on the identifier of the first beam, the identifier of the third communication device, and the first offset value in the first correspondence. In this case, the implementation of the correspondence between the three parameters "beam + offset value + identifier of the third communication device" and the resources in the first correspondence is similar to the implementation of the correspondence between the two parameters "beam + first parameter" and the resources described in the above embodiments. For details, please refer to the relevant descriptions in the above embodiments, which will not be repeated here.

[0273] Alternatively, the first parameter may include the identifier of the terminal device and an offset value. In this case, the first correspondence includes the identifier of at least one beam, at least one offset value, the identifier of at least one terminal device, and a correspondence between at least one resource. That is, the first communication device can determine M second resources based on the identifier of the first beam, the identifier of the first communication device, and the first offset value in the first correspondence. In this case, the implementation of the correspondence between the three parameters "beam + identifier of the terminal device + offset value" and the resources in the first correspondence is similar to the implementation of the correspondence between the two parameters "beam + first parameter" and the resources described in the above embodiments. For details, please refer to the relevant descriptions in the above embodiments, which will not be repeated here.

[0274] Alternatively, the first parameter may include the identifier of the terminal device, the offset value, and the identifier of the third communication device. In this case, the first correspondence includes the identifier of at least one beam, at least one offset value, at least one identifier of the third communication device, at least one identifier of the terminal device, and the correspondence between at least one resource. That is, the first communication device can determine M second resources in the first correspondence based on the identifier of the first beam, the identifier of the first communication device, the identifier of the third communication device, and the first offset value. In this case, the implementation of the correspondence between the four parameters "beam + identifier of the terminal device + identifier of the third communication device + offset value" and the resources in the first correspondence is similar to the implementation of the correspondence between the two parameters "beam + first parameter" and the resources described in the above embodiments. For details, please refer to the relevant descriptions in the above embodiments, which will not be repeated here.

[0275] For example, taking the first parameter as including the identifier of the third communication device and the identifier of the terminal device, the first correspondence may include the contents shown in Table 4:

[0276] Table 4

[0277] Identification of the third communication device PF number Second resource number Third communication device #1 (Beam identifier + terminal device identifier) ​​modNS 0 Third communication device #2 (Beam identifier + terminal device identifier) ​​modNS 2 … … …

[0278] The implementation of each parameter in Table 4 can be found in the relevant descriptions of the three examples of the first parameter mentioned above, and will not be repeated here. Alternatively, the PF number in Table 4 can be replaced with SFN. In this case, the relationship between SFN and the beam identifier satisfies (10):

[0279] (SFN+PF_offset)mod T=(T div NS)*((beam identifier+UE_ID)mod NP) relation(10);

[0280] Wherein, UE_ID represents the identifier of the terminal device.

[0281] Alternatively, taking the example where the first parameter includes the identifier of the third communication device, the identifier of the terminal device, and the offset value, the content shown in Table 5 can be included:

[0282] Table 5

[0283] Identification of the third communication device PF number Second resource number Third communication device #1 (Beam identifier + terminal device identifier + offset value) mod NS 0 Third communication device #2 (Beam identifier + terminal device identifier + offset value) mod NS 2 … … …

[0284] The implementation of each parameter in Table 5 can be found in the relevant descriptions of the three examples of the first parameter mentioned above, and will not be repeated here. Alternatively, the PF number in Table 5 can be replaced with SFN. In this case, the relationship between SFN and the beam identifier satisfies (11):

[0285] (SFN+PF_offset)mod T=(T div NS)*((beam identifier+UE_ID+offset value)mod NP) relation (11); where UE_ID represents the identifier of the terminal device.

[0286] For example, the offset values ​​corresponding to the identifiers of different third communication devices can be the same or different. Taking the offset value of 0 for third communication device #1 and the offset value of 1 for third communication device #2 as an example, Table 5 can be replaced with the content shown in Table 6:

[0287] Table 6

[0288] Identification of the third communication device SFN Second resource number Third communication device #1 (Beam identifier + terminal device identifier) ​​modNS 0 Third communication device #2 (Beam identifier + terminal device identifier) ​​+ 1 mod NS 2 … … …

[0289] The implementation of each parameter in Table 6 can be found in the relevant descriptions of the three examples of the first parameter mentioned above, and will not be repeated here. Alternatively, the PF number in Table 6 can be replaced with SFN. In this case, the SFN corresponding to the third communication device #1 satisfies the relationship (12-1) with the beam identifier, and the SFN corresponding to the third communication device #2 satisfies the relationship (12-2) with the beam identifier.

[0290] (SFN+PF_offset)mod T=(T div NS)*((beam identifier+UE_ID)mod NP) relation (12-1);

[0291] (SFN+PF_offset)mod T=(T div NS)*((beam identifier+UE_ID+1)mod NP) relation (12-2);

[0292] Wherein, UE_ID represents the identifier of the terminal device.

[0293] It should be noted that when a first parameter exists in the aforementioned first correspondence, the second resource is determined by the calculation method of adding the remainders (such as the remainder of adding the beam identifier and the terminal device identifier, or the remainder of adding the beam identifier, offset value, and terminal device identifier). In fact, the second resource can also be determined by other calculation methods besides adding the remainders in the first correspondence. For example, the second resource can be determined by the calculation method of multiplying the remainders (such as the remainder of adding the beam identifier and the terminal device identifier, or the remainder of adding the beam identifier, offset value, and terminal device identifier). The specific implementation is similar to the implementation of determining the second resource based on the calculation method of adding the remainders described above. For details, please refer to the relevant descriptions in the above embodiments, which will not be repeated here.

[0294] In one implementation, when a first parameter exists in the first correspondence, the calculation method used in the first correspondence can be pre-configured to determine the corresponding first correspondence, and then M second resources can be determined based on the first correspondence.

[0295] For example, the calculation method can be predefined by a protocol. Alternatively, it can be pre-agreed between the first communication device and the second or third communication device; for instance, the calculation method can be determined by the second communication device and communicated to the first communication device, and the first correspondence can be pre-determined by the third communication device and communicated to the first communication device.

[0296] For example, multiple calculation methods can be pre-configured, so that before step S602, the second or third communication device informs the first communication device which calculation method is used in the first correspondence. Multiple calculation methods may include those shown in Table 7:

[0297] Table 7

[0298] serial number Calculation method 0 Multiply and take the remainder 1 Add and take the remainder … …

[0299] The second or third communication device can indicate which calculation method is used in the first correspondence through the sixth indication information. For example, the sixth indication information can indicate number 0, indicating that the calculation method used in the first correspondence is multiplication and taking the remainder; the sixth indication information can indicate number 1, indicating that the calculation method used in the first correspondence is addition and taking the remainder.

[0300] For example, the sixth instruction information can be carried in any of the following: SIB, RRC signaling, MAC-CE signaling, or DCI.

[0301] It should be noted that the above embodiments all use the example of "each beam corresponding to a different second resource" to illustrate the implementation of M second resources. In reality, among the multiple beams of the second communication device, some beams may correspond to the same second resource. For example, the second beam of the second communication device may also correspond to the aforementioned M second resources. The implementation of M second resources in this case will be described in detail below.

[0302] Combining the two possible implementations described above, optionally, in one scenario, the paging device receiving the wake-up signal on the second beam includes a fourth communication device. The fourth communication device is located within the coverage area of ​​the second beam. That is, before step S602, the paging method further includes step S607:

[0303] S607, the second communication device sends a second signal to the fourth communication device on the first resource; correspondingly, the fourth communication device receives the second signal from the second communication device on the first resource.

[0304] The second signal is carried on the second beam of the second communication device; the second signal is used to wake up the first communication device. At this time, the second communication device can determine M second resources based on the second beam; and then execute a paging process based on the M second resources. For example, the implementation of the fourth communication device is similar to that of the first communication device described above; please refer to the relevant description of the first communication device for details, which will not be repeated here.

[0305] For example, since the content (e.g., sequence) of the signals transmitted on each beam of the second communication device is the same—that is, the content (e.g., sequence) of the first signal and the second signal is the same—the second signal can also be WUS, or LP-WUS, or it can be other signals with wake-up functionality.

[0306] For example, the fourth communication device may be a terminal device (such as a UE).

[0307] Scenario 2: The correspondence between beams and resources in the first correspondence is "many to one".

[0308] For example, in scenario two, different beams in the first correspondence can correspond to the same resource (i.e., multiple beams correspond to the same second resource).

[0309] In one example, the first correspondence includes a correspondence between two types of parameters: beam identifiers and resources. That is, the first correspondence includes a correspondence between at least one beam identifier and at least one resource. Therefore, the first communication device can determine M second resources from the first correspondence based on the first beam identifier. For example, the first correspondence may include the contents shown in Table 8:

[0310] Table 8

[0311]

[0312] As shown in Table 8, beams identified as 0 and 1 correspond to the same second resource (i.e., second resource 2 in PF 0).

[0313] Alternatively, the first correspondence can also be represented by a formula. For example, for a beam with a beam identifier of 0, the corresponding PF number satisfies: beam identifier mod NS; and the corresponding second resource number satisfies: beam identifier mod NP. For a beam with a beam identifier of 1, the corresponding PF number satisfies: (beam identifier - 1) mod NS; and the corresponding second resource number satisfies: (beam identifier - 1) mod NP.

[0314] In one possible implementation, the PF where the second resource is located can also be represented by SFN. In this case, for a beam with a beam identifier of 0, the corresponding PF number satisfies: (SFN + PF_offset) mod T = (T div NS) * (beam identifier mod NP); for a beam with a beam identifier of 1, the corresponding PF number satisfies: (SFN + PF_offset) mod T = (T div NS) * ((beam identifier - 1) mod NP)

[0315] For example, the implementation of beam identification in this example can be found in the relevant description of a possible implementation of Scenario 1 above, and will not be repeated here.

[0316] In another example, the first correspondence includes the correspondence between three types of parameters: beam identifier, first parameter, and resource. That is, the first correspondence includes the correspondence between at least one beam identifier, at least one first parameter, and at least one resource. Therefore, the first communication device can determine M second resources based on the first beam identifier and the first parameter within the first correspondence. The implementation of the first parameter can be found in the description of another possible implementation of scenario one above, and will not be repeated here.

[0317] For example, in this example, the correspondence between (beam + first parameter) and resource is "many-to-one," meaning that multiple beams and one first parameter correspond to the same resource, one beam and multiple first parameters correspond to the same resource, and / or, multiple beams and multiple first parameters correspond to the same resource. For instance, at least one beam includes beam #1 and beam #2, at least one first parameter includes first parameter #1 and first parameter #2, and at least one resource includes resources #1 to #2; wherein, when multiple beams and one first parameter correspond to the same resource, beam #1 and first parameter #1, and beam #2 and first parameter #1 both correspond to resource #1, and beam #1 and first parameter #2 both correspond to resource #2. When one beam and multiple first parameters correspond to the same resource, beam #1 and first parameter #1, and beam #1 and first parameter #2 both correspond to resource #1, and beam #2 and first parameter #2 both correspond to resource #2. When multiple beams correspond to the same resource with multiple first parameters, beam #1 and first parameter #1, beam #2 and first parameter #2 all correspond to resource #1, and beam #1 and first parameter #2, and beam #2 and first parameter #1 all correspond to resource #2.

[0318] Specifically, for adjacent beams (such as a beam with a beam identifier of 0 and a beam with a beam identifier of 1), the second resource corresponding to the beam with a beam identifier of 0 satisfies the relevant implementation in another possible implementation of scenario 2 above (such as satisfying one or more of the correspondences in relation (4-1) to relation (12-2); further, the correspondence between the beam with a beam identifier of 1 and its corresponding second resource is: the correspondence obtained by replacing "beam identifier" with "beam identifier-1" in the correspondence between the beam with a beam identifier of 1 and its corresponding second resource.

[0319] In other words, for a beam with a beam identifier of 0, the corresponding PF number satisfies: (beam identifier + first parameter) mod NS; and the corresponding second resource number satisfies: (beam identifier + first parameter) mod NP. For a beam with a beam identifier of 1, the corresponding PF number satisfies: (beam identifier + first parameter - 1) mod NS; and the corresponding second resource number satisfies: (beam identifier + first parameter - 1) mod NP.

[0320] Alternatively, the PF where the second resource is located can also be represented by SFN. In this case, for a beam with a beam identifier of 0, the number of its corresponding PF satisfies: (SFN+PF_offset)mod T=(T div NS)*((beam identifier + first parameter)mod NP); for a beam with a beam identifier of 1, the number of its corresponding PF satisfies: (SFN+PF_offset)mod T=(Tdiv NS)*((beam identifier + first parameter - 1)mod NP).

[0321] For example, when the first parameter is the identifier of the terminal device, for a beam with an identifier of 0, the corresponding PF number satisfies: beam identifier mod NS; and the corresponding second resource number satisfies: (beam identifier + terminal device identifier) ​​mod NP. For a beam with an identifier of 1, the corresponding PF number satisfies: (beam identifier + terminal device identifier - 1) mod NS; and the corresponding second resource number satisfies: (beam identifier - 1) mod NP.

[0322] Optionally, in one scenario, the paging device that receives the wake-up signal on the second beam may also include a first communication device. That is, before step S602, the paging method further includes step S608:

[0323] S608, the second communication device sends a second signal to the first communication device on the first resource; correspondingly, the first communication device receives the second signal from the second communication device on the first resource.

[0324] The second signal is carried on the second beam of the second communication device; the second signal is used to wake up the first communication device. At this time, the first communication device can determine M second resources based on the first beam and / or the second beam.

[0325] For example, since the content (e.g., sequence) of the signals transmitted on each beam of the second communication device is the same—that is, the content (e.g., sequence) of the first signal and the second signal is the same—the second signal can also be WUS, or LP-WUS, or it can be other signals with wake-up functionality.

[0326] It should be noted that the above embodiments exemplify some implementations of the first correspondence relationship, and do not mean that the first correspondence relationship only includes the above implementations. In fact, the first correspondence relationship described in this application may also include any possible implementations other than those in the above embodiments, and this application does not limit it.

[0327] Based on the two scenarios described above, for WUS devices and paging devices located in different geographical locations, typically one WUS device manages the paging devices within the same area. Specifically, the WUS device initiates the paging process between the paging device and the paging device via a signal carried on its low-power wake-up signal timing; that is, there is a correspondence between the low-power wake-up signal timing and the paging timing of the paging device (i.e., the first correspondence). Therefore, for the second communication device that sends the signal to wake up the first communication device (i.e., the first signal), and the third communication device that sends the paging message, since the first and third communication devices are within the same area, the second communication device manages the third communication device; that is, there is a correspondence between the low-power wake-up signal timing of the second communication device (i.e., the first resource) and the paging timing of the third communication device (i.e., the second resource). Thus, the first communication device can determine the paging timing based on this correspondence, thereby completing the paging process.

[0328] For the first communication device, there is a higher probability that a nearby third communication device will initiate paging together with the first communication device. Therefore, it is advisable to have the third communication device near the first communication device initiate paging to the first communication device to improve paging efficiency. That is, the paging timing determined by the first communication device is the paging timing of the third communication device near the first communication device. Specifically, since the first communication device can receive the wake-up signal sent by the second communication device on different beams of the second communication device when it is in different locations (for example, receiving the first signal on the first beam of the second communication device, i.e., the first signal is carried on the first beam of the second communication device); thus, a correspondence can be established between different beams and the paging timing corresponding to the low-power wake-up signal timing (e.g., the first beam corresponds to M second resources). For example, the paging timing of the third communication device in a certain beam direction is the paging timing corresponding to that beam (e.g., if the beam direction of the first beam includes N third communication devices, the M second resources are the second resources of the N third communication devices). In other words, in the paging process, only the paging device in one beam direction (i.e., the third communication device) participates in paging the paged device (the first communication device). Compared with the scheme where all paging devices managed by the WUS device simultaneously initiate paging to the paged device, this can reduce paging power consumption and paging resource consumption, thereby increasing paging capacity.

[0331] The foregoing primarily describes the solutions provided in this application from the perspective of device-to-device interaction. It is understood that each device, in order to achieve the aforementioned functions, includes corresponding hardware structures and / or software modules for executing each function. Those skilled in the art should readily recognize that, based on the algorithm steps of the examples described in conjunction with the embodiments disclosed herein, this application can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed in hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of this application.

[0332] This application embodiment can divide each device into functional modules according to the above method example. For example, each function can be divided into a separate functional module, or two or more functions can be integrated into one processing module. The integrated module can be implemented in hardware or as a software functional module. The module division in this application embodiment is illustrative and represents a logical functional division; in actual implementation, there may be other division methods.

[0333] When dividing each function into modules according to its corresponding function. Figure 13 A communication device 130 is shown, which can perform the above-described...

Furthermore, Figure 13 The communication device 130 shown may also include a memory.

Exemplarily, the controller is primarily responsible for instruction decoding and issuing control signals for the operations corresponding to the instructions. The ALU is primarily responsible for performing fixed-point or floating-point arithmetic operations, shift operations, and logical operations, and can also perform address operations and translations.
