1 / 73 METHOD AND APPARATUS OF COMMUNICATION TECHNICAL FIELD

[0001] This application relates to the field of communication technologies and, in particular, to a method and apparatus for communication. BACKGROUND

[0002] A paging mechanism means that when a network needs to send data to a UE, it sends a paging message to allow an idle or inactive terminal device to enter connected mode. When a discontinuous reception (DRX) mechanism is configured for a terminal device, a cycle (referred to as a paging cycle below) in which the network pages the terminal device can be determined based on a DRX cycle of the terminal device. To adapt to the low power consumption of the Internet of Things, an extended discontinuous reception (eDRX) mechanism was introduced based on the XRD mechanism. In an eDRX cycle, the terminal device is in a deep hibernation period most of the time and monitors a paging message only in a paging time window (PTW) based on the DRX mechanism.

[0003] In a relay scenario, a remote terminal sends information related to a remote terminal's paging cycle to a relay terminal, so that the relay terminal can monitor a paging message in the remote terminal's paging cycle and forward the paging message obtained through monitoring to the remote terminal. This further implements remote terminal paging over a network.

[0004] However, when the remote terminal provides information related to the paging cycle to the terminal of Petition 870250099585, dated 10 / 30 / 2025, page 8 / 87 2 / 73 retransmission, the retransmission function is unreliable and the device's power consumption is high. SUMMARY

[0005] The implementations of this application provide a method and a communication device, such that a relay terminal provides, to a remote terminal, a relay service that adapts to an eDRX mechanism. This further improves the reliability of the relay function and reduces the terminal's power consumption.

[0006] According to a first aspect, a communication method is provided and applied to a first terminal or to a chip in a first terminal. A second terminal provides a relay service to the first terminal. For example, the method is applied to the first terminal. The method includes: determining first information, where the first information includes at least one parameter; and sending the first information to the second terminal.The first cycle information is configured for the first terminal; the first cycle information indicates an extended discontinuous reception (eDRX) cycle from the first terminal; at least one parameter is used to determine the second cycle information; the second cycle information is used to determine a cycle in which a network sends a pager message to the first terminal; at least one parameter is related to the second information; and the second information includes at least one of the following: partial or all of the information in the first cycle information, and a paging time window (PTW) from the first terminal.

[0007] In embodiments of this application, the first terminal may determine, based on information (for example, an eDRX cycle and a PTW) relating to an eDRX mechanism, at least one parameter to be sent to the second terminal, such that a paging cycle determined by the second terminal with Petition 870250099585, dated 10 / 30 / 2025, p. 9 / 87 3 / 73 based on at least one parameter that can adapt to the eDRX mechanism of the first terminal. This can improve the reliability of a relay function and reduce the terminal's power consumption.

[0008] In a possible project, determining the first information includes: determining the first information based on at least one of the following: limit information, eDRX information, discontinuous reception (DRX) information, PTW information, and radio resource control (RRC) information. Limit information indicates a first limit, and the first limit is a maximum value within a range of values ​​of an eDRX cycle. eDRX cycle information indicates the eDRX cycle of the first terminal. XRD information indicates an XRD cycle of the first terminal; PTW information indicates the PTW of the first terminal. The RRC mode information indicates the RRC mode of the first terminal.

[0009] Several specific implementations are listed below.

[0010] In a possible project, determining the first information based on at least one of the following: limit information, eDRX information, discontinuous reception DRX information, PTW information, and RRC radio resource control mode information includes: determining at least one parameter in the first information based on the limit information and the eDRX information.

[0011] For example, at least one parameter is determined based on a value relationship between the first limit and the eDRX cycle of the first terminal.

[0012] For example, if any eDRX cycle of the first terminal is less than or equal to the first limit, at least one parameter will be determined based on any eDRX cycle, where the second piece of information includes any eDRX cycle. If by Petition 870250099585, dated 10 / 30 / 2025, p. 10 / 87 4 / 73 minus one eDRX cycle of the first terminal exceeds the first limit, at least one parameter will be determined based on the eDRX cycle of the first terminal and / or a standard eDRX cycle, where the second piece of information includes the PTW of the first terminal, and also includes the eDRX cycle of the first terminal or the eDRX cycle. Standard XRD.

[0013] In other words, if an eDRX cycle that does not exceed the first limit is configured for the first terminal, the eDRX cycle can be used to determine at least one parameter. For example, if an eDRX cycle configured by a higher layer for the first terminal does not exceed the first limit, the second piece of information could include the eDRX cycle configured by the higher layer for the first terminal. If an eDRX cycle configured by an RRC layer for the first terminal does not exceed the first limit, the second piece of information could include the eDRX cycle configured by the RRC layer for the first terminal.

[0014] If an eDRX cycle that exceeds the first limit is configured for the first terminal, the PTW can be used to determine at least one parameter. For example, if the eDRX cycle configured by the upper layer for the first terminal exceeds the first limit, the second piece of information may include a PTW configured by the upper layer for the first terminal. If the eDRX cycle configured by the RRC layer for the first terminal exceeds the first limit, the second piece of information may include a PTW configured by the RRC layer for the first terminal.

[0015] In a possible project, the determination of the first information based on at least one of the following: limit information, eDRX information, discontinuous reception DRX information, PTW information, and RRC radio resource control mode information includes: determining at least one parameter in the first information based on the eDRX information. Petition 870250099585, dated 10 / 30 / 2025, p. 11 / 87 5 / 73 and in the XRD information.

[0016] For example, the eDRX cycle of the first terminal includes the eDRX cycle configured by the upper layer and / or the eDRX cycle configured by the RRC layer for the first terminal, and the DRX cycle of the first terminal includes a DRX cycle configured by the upper layer and / or a DRX cycle configured by the RRC layer for the first terminal. The determination of at least one parameter in the first information based on the eDRX information and the DRX information includes: if the upper layer does not configure the eDRX cycle for the first terminal, the determination of at least one parameter based on the DRX cycle configured by the upper layer for the first terminal and / or the default DRX cycle, where the second information includes the PTW configured by the upper layer for the first terminal and also includes the DRX cycle configured by the upper layer for the first terminal and / or the default DRX cycle;and / or if the RRC layer does not configure the eDRX cycle for the first terminal, determine at least one parameter based on the DRX cycle configured by the RRC layer for the first terminal and / or the default DRX cycle, where the second piece of information includes a PTW configured by the RRC layer for the first terminal and also includes the DRX cycle configured by the RRC layer for the first terminal and / or the default DRX cycle.

[0017] In other words, if an eDRX cycle that does not exceed the first limit is configured for the first terminal, the eDRX cycle can be used to determine at least one parameter. If an eDRX cycle that exceeds the first limit is configured for the first terminal, the PTW, the DRX cycle, and / or the standard DRX cycle can be used to determine at least one parameter.

[0018] This can reduce the terminal's power consumption and improve paging efficiency.

[0019] In a possible project, the determination of the first Petition 870250099585, dated 10 / 30 / 2025, page 12 / 87 6 / 73 Information based on at least one of the following: limit information, eDRX information, discontinuous reception DRX information, PTW information, and RRC radio resource control mode information includes: determining at least one parameter in the first piece of information based on the PTW information.

[0020] For example, the PTW of the first terminal includes the PTWs configured by the upper layer and the RRC layer for the first terminal. Determining at least one parameter in the first piece of information based on the PTW information includes: determining at least one parameter based on a value relationship between the PTW configured by the upper layer for the first terminal and the PTW configured by the RRC layer for the first terminal; and / or determining at least one parameter based on an overlap mode between the PTW configured by the upper layer for the first terminal and the PTW configured by the RRC layer for the first terminal.

[0021] For example, determining at least one parameter based on the value ratio between the PTW configured by the upper layer for the first terminal and the PTW configured by the RRC layer for the first terminal includes: if the PTW configured by the upper layer for the first terminal is greater than the PTW configured by the RRC layer for the first terminal, determining at least one parameter based on the DRX cycle configured by the upper layer for the first terminal and / or the default DRX cycle, where the second piece of information includes the PTW configured by the upper layer for the first terminal and also includes the DRX cycle configured by the upper layer for the first terminal and / or the default DRX cycle;or if the PTW configured by the upper layer for the first terminal is less than the PTW configured by the RRC layer for the first terminal, determine at least one parameter based on the DRX cycle configured by the RRC layer for the first terminal and / or the default DRX cycle, where the second piece of information includes; Petition 870250099585, dated 10 / 30 / 2025, p. 13 / 87 7 / 73 PTW configured by the RRC layer for the first terminal and also includes the DRX cycle configured by the RRC layer for the first terminal and / or the standard DRX cycle.

[0022] For example, determining at least one parameter based on the overlap mode between the PTW configured by the upper layer for the first terminal and the PTW configured by the RRC layer for the first terminal includes: if the PTW configured by the upper layer for the first terminal does not overlap with the PTW configured by the RRC layer for the first terminal, determining at least one parameter based on the DRX cycles configured by the upper layer and the RRC layer for the first terminal and / or the default DRX cycle, where the second piece of information includes the PTWs configured by the upper layer and the RRC layer for the first terminal, and also includes the DRX cycles configured by the upper layer and the RRC layer for the first terminal and / or the default DRX cycle;or if there is an overlapping part and a non-overlapping part between the PTW configured by the upper layer for the first terminal and the PTW configured by the RRC layer for the first terminal, for the overlapping part, determine at least one parameter based on the DRX cycle configured by the upper layer for the first terminal, the DRX cycle configured by the RRC layer for the first terminal and the default DRX cycle, where the second piece of information includes the PTWs configured by the upper layer and the RRC layer for the first terminal and also includes the DRX cycle configured by the upper layer for the first terminal, the DRX cycle configured by the RRC layer for the first terminal and the default DRX cycle;and for the non-overlapping part, determine at least one parameter based on the standard XDR cycle and an XDR cycle in a larger PTW in the PTW configured by the upper layer for the first terminal and the PTW configured by the RRC layer for the first terminal, where the second; Petition 870250099585, dated 10 / 30 / 2025, p. 14 / 87 8 / 73 information includes the higher PTW, the XRD cycle at the higher PTW, and the standard XRD cycle.

[0023] In a possible project, the determination of the first information based on at least one of the following: boundary information, eDRX information, discontinuous reception DRX information, PTW information, and RRC radio resource control mode information includes: if the RRC mode is an RRC idle mode, determine at least one parameter based on the eDRX cycle configured by the upper layer for the first terminal; or if the RRC mode is an RRC inactive mode, determine at least one parameter based on the eDRX cycle configured by the upper layer and / or the eDRX cycle configured by the RRC layer for the first terminal.

[0024] When the first terminal is in different RRC modes, network devices that initiate paging to the first terminal may be different. Therefore, the first terminal determines, based on the RRC mode, a parameter provided to the second terminal, to help improve the reliability of the determination of a paging cycle by the second terminal.

[0025] In a possible project, the fact that at least one parameter is related to the second piece of information includes: At least one parameter includes partial or all information in the second piece of information; and / or at least one parameter includes a statistical value of partial or all information in the second piece of information. Optionally, the statistical value of partial or all information in the second piece of information is a minimum value of partial or all information in the second piece of information.

[0026] Certainly, the above is just one example, and real-world application is not limited to it.

[0027] In a possible project, sending the first piece of information to the second terminal includes: when the information Petition 870250099585, dated 10 / 30 / 2025, page 15 / 87 9 / 73 of the second terminal's capacity and the capacity information of a service cell of the second terminal meet a predefined condition, sending the first information to the second terminal. The second terminal's capacity information indicates whether or not the second terminal supports an eDRX mechanism, the service cell's capacity information indicates whether or not the service cell supports the eDRX mechanism, and the predefined condition includes that the second terminal supports the eDRX mechanism and the service cell supports the eDRX mechanism.

[0028] In this design method, the first terminal determines, based on the capacity information of the second terminal and the capacity information of the second terminal's service cell, whether it should provide the eDRX mechanism-related information from the first terminal to the second terminal, in order to reduce the waste of transmission resources and further reduce the terminal's energy consumption.

[0029] In a possible project, the method also includes: obtaining the capacity information of the second terminal and / or the capacity information of the service cell of the second terminal from the second terminal. Certainly, the real application is not limited to this.

[0030] In a possible project, the service cell supports the eDRX mechanism, including: When the RRC mode of the first terminal is RRC idle mode and / or RRC inactive mode, the service cell supports the eDRX mechanism. Sending the first information to the second terminal includes: when the service cell supports the eDRX mechanism, sending the first information.

[0031] In this design approach, it is possible to distinguish whether the service cell supports the eDRX mechanism when the second terminal is in different RRC modes, to improve the accuracy of the service cell capacity information and Petition 870250099585, dated 10 / 30 / 2025, p. 16 / 87 10 / 73 further improve the reliability of the relay service.

[0032] In a possible project, the method also includes: determining that the second terminal is capable of receiving, for the first terminal, a paging message sent over the network to the second terminal and sending the first information to the second terminal.

[0033] This can reduce the waste of transmission resources and terminal energy consumption, as well as further reducing the implementation complexity on the first side of the terminal.

[0034] In a possible design, the method also includes: receiving a sixth indication from the second terminal. The sixth indication indicates that the second terminal is able to receive, for the first terminal, the paging message sent over the network to the first terminal, or indicates to the first terminal to send at least one parameter. After receiving the sixth indication, the first terminal sends the first information to the second terminal.

[0035] This can reduce the waste of transmission resources and energy consumption at the terminal, as well as further reducing the complexity of implementation on the first side of the terminal.

[0036] According to a second aspect, a communication method is provided and applied to a first terminal or to a chip in a first terminal. A second terminal provides a relay service to the first terminal, and the second terminal and / or a service cell of the first terminal do not support an eDRX mechanism. For example, the method is applied to the first terminal. The method includes: determining the first information based on the eDRX information from the first terminal, where the first information includes at least one parameter; and sending the first information to the second terminal, where at least one parameter is used to determine the second information.

[0037] In embodiments of this application, when the second terminal and / or the service cell of the first terminal do not support the eDRX mechanism, the first terminal may set a value of one DRX cycle of the first terminal to a value that matches the eDRX mechanism, so that the relay service provided by the second terminal to the first terminal can match the eDRX mechanism of the first terminal. This improves the reliability of a relay function and reduces the terminal's power consumption.

[0038] It can be understood that the second terminal and / or the service cell of the first terminal not supporting the eDRX mechanism includes the following cases: 1. The second terminal does not support the eDRX mechanism. 2. The service cell of the first terminal does not support the eDRX mechanism. 3. The second terminal does not support the eDRX mechanism, and the service cell of the first terminal does not support the eDRX mechanism.

[0039] In a possible project, a service cell of the second terminal supports the eDRX mechanism.

[0040] In a possible project, the second terminal service cell supports the eDRX mechanism including: When a second terminal RRC mode is an idle RRC mode and / or an inactive RRC mode, the second terminal service cell supports the eDRX mechanism.

[0074] Furthermore, unless otherwise specified, ordinal numbers such as first and second in the modalities of this application are to distinguish between a plurality of objects, but are not intended to limit an order, a sequence of time, priorities, or importance of the plurality of objects. For example, a first priority criterion and a second priority criterion are used merely to distinguish different criteria and not to indicate different contents, priorities, or degrees of importance of the two types of criteria.

[0075] Furthermore, the terms include / comprise and have in the embodiments, claims and drawings attached to this application are not mutually exclusive. For example, a process, a method, a system, a product or a device that includes a series of steps or modules is not limited to the steps or modules listed and may also include steps or modules that are not listed.

[0076] The modalities of this application are primarily applied to a scenario where a device provides a relay service to another device (hereinafter referred to as a relay scenario), for example, a user equipment-to-network (UE2N) relay scenario, i.e., a relay terminal (relay UE) provides a network connection to a remote terminal (remote UE). It can be understood that, in the relay scenario, there may be one or more relay terminals. For ease of description, the following example primarily uses one relay terminal.

[0077] FIG. 1 is a diagram of a communication system according to an embodiment of this application. The communication system includes a terminal device 101, a device Petition 870250099585, dated 10 / 30 / 2025, page 29 / 87 23 / 73 terminal 102 and a network device 103.

[0078] Network device 103 is configured to perform access management and switching management on the terminal device and to communicate with a core network.

[0079] Network device 103 includes a radio access network (RAN) device. The access network device may also sometimes be referred to as an access network node, RAN node, RAN entity, access node, RAN network element, or similar, and is part of the communication system to assist the terminal in implementing radio access.

[0080] The access network device is, for example, a base station (BS) or includes a base station, a radio resource management device configured to control the base station, and the like.For example, the base station may include an evolved NodeB (eNB or e-NodeB) in a long-term evolution (LTE) system or a long-term evolution-advanced (LTE-A) system; it may include a next-generation NodeB (gNB), an evolved next-generation NodeB (ng-eNB), or an enhanced next-generation NodeB (en-gNB) in a new radio (NR) system of fifth-generation (5G) mobile communication technology; and it may include a central unit (CU) and a distributed unit (DU) in a cloud radio access network (Cloud RAN) system. This is not limited in embodiments of this application.

[0081] In one possible scenario, a plurality of RAN nodes coordinate to assist the terminal in implementing radio access, and different RAN nodes separately implement some base station functions. For example, a RAN node can be a central unit (CU), a distributed unit (DU), or a control plane (CP). Petition 870250099585, dated 10 / 30 / 2025, page 30 / 87 24 / 73 CU, a user plane (UP) of CU, a radio unit (RU) or similar. The CU and DU may be arranged separately or may be included in the same network element, for example, a baseband unit (BBU). The RU may be included in a radio frequency device or in a radio frequency unit, for example, in a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH).

[0082] In different systems, the CU (or CU-CP and CU-UP), DU, or RU may alternatively have different names, but an expert in the field can understand their meanings. For example, in an ORAN system, the CU may also be called OCU (open CU), the DU may also be called O-DU, the CU-CP may also be called O-CU-CP, the CU-UP may also be called O-CU-UP, and the RU may also be called O-RU. For ease of description, the CU, CU-CP, CU-UP, DU, and RU are used as examples for description in this application. Any of the CU (or CU-CP or CU-UP), DU, and RU in this application may be implemented using a software module, a hardware module, or a combination of a software module and a hardware module.

[0083] The network elements in the core network are classified into two types: a user plane network element and a control plane network element. The user plane network element includes a user plane function (UPF) network element, and the control plane network element includes an access and mobility management function (AMF) network element, a session management function (SMF) network element, a unified data management (UDM) network element, and a control function network element. Petition 870250099585, dated 10 / 30 / 2025, page 31 / 87 25 / 73 policy control function (PCF), an application function (AF) network element, an authentication server function (AUSF) network element, a network slice selection function (NSSF) network element, a network slice-specific authentication and authorization function (NSSAAF) network element, a network exposure function (NEF) network element, and similar elements.

[0084] The terminal device may also be referred to as a terminal, user equipment (UE), mobile station, mobile terminal, or similar terms. The terminal device can be widely used in various scenarios, for example, device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable device, smart transportation, and smart city.The terminal device may be a mobile phone, a tablet, a computer with a wireless transceiver function, a wearable device, a vehicle, an unmanned aerial vehicle, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home device, or similar. Neither a specific technology nor a specific device form used by the terminal device is limited in embodiments of this application.

[0085] Terminal device 101 can communicate with one or more network devices on one or more communication systems and accept a network service provided by the network device. The network device described here includes, Petition 870250099585, dated 10 / 30 / 2025, page 32 / 87 26 / 73 among others, the network device 103 shown in the figure. For example, in this embodiment of this application, terminal device 101 and terminal device 102 may each be a mobile phone (or so-called cellular phone) or a computer with a mobile terminal. Alternatively, terminal device 101 and terminal device 102 may each be a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device. Alternatively, terminal device 101 and terminal device 102 may each be a communication chip with a communication module. It should be understood that terminal device 101 may be configured to support communication with the network device via a universal user-to-network interface (Uu).

[0086] Terminal device 101 and terminal device 102 can be configured to support SideLink (SL) transmission. Unlike an uplink or a downlink, SL is a communication mechanism in which devices communicate directly with each other without using a network device. For example, SL communication can be performed between terminal device 101 and terminal device 102 via a Direct Communication Air Interface (PC5) (i.e., an air interface used for SL communication between terminals). It should be understood that, in this application, SL communication can include SL unicast communication, multicast communication, and broadcast communication.

[0087] In addition, terminal device 101 and terminal device 102 can be configured to support relay transmission. For example, terminal device 101 can provide a relay service to terminal device 102 and provide a connection to network device 103 for terminal device 102, i.e., implement a U2N relay function. For example, the device Petition 870250099585, dated 10 / 30 / 2025, page 33 / 87 Terminal 101 can receive information from network device 101 and forward it to terminal device 102, and receive information from terminal device 101 and forward it to network device 103. Therefore, terminal device 102 can communicate with network device 103 using terminal device 101.

[0088] For ease of description, in this application, a terminal device that provides a relay service is referred to as a relay terminal (relay UE), and a terminal device that uses the relay service is referred to as a remote terminal (remote UE). For example, in the scenario shown in FIG. 1, terminal device 101 can be used as a relay terminal, and terminal device 102 can be used as a remote terminal.

[0089] The communication system shown in FIG. 1 can support various radio access technologies (RAT). For example, the communication system shown in FIG. 1 can be a fourth-generation (4th generation, 4G) communication system (which can also be called a long-term evolution (LTE) communication system), a 5G communication system (which can also be called a new radio (NR) communication system), a 6G communication system, or a future-oriented evolved system.

[0090] It may be understood that the network architecture and service scenario described in the embodiments of this request are intended to describe the technical solutions in the embodiments of this request more clearly and do not constitute a limitation to the technical solutions provided in the embodiments of this request. A person skilled in the art may know that: With the evolution of network architecture and the emergence of new service scenarios, the technical solutions provided in the embodiments of this request are also applicable to similar technical problems. Petition 870250099585, dated 10 / 30 / 2025, p. 34 / 87 28 / 73

[0091] The protocol stacks in a relay scenario include a user-plane protocol stack and a control-plane protocol stack. FIG. 2A and FIG. 2B are diagrams, respectively, of a U2N user-plane protocol stack and a U2N control-plane protocol stack in a U2N relay scenario. The relays include a layer 3 (L3) relay and a layer 2 (L2) relay.For the U2N L2 relay, regardless of the user plane or control plane, a relay adaptation layer (i.e., a sidelink relay adaptation protocol, SRAP) layer is located above a radio link control (RLC) layer of a Uu interface between a relay terminal and a network device (e.g., a gNB), and a data packet from the relay terminal is retransmitted below a packet data convergence protocol (PDCP) layer. In FIG. 2A and FIG. 2B, a PC5-SRAP is used to represent the relay adaptation layer. Layer 3 retransmission is a retransmission based on an Internet Protocol (IP) layer.

[0092] See FIG. 3. U2N relay coverage scenarios include the following types.

[0093] Scenario 1: The relay terminal is in a service cell and a remote terminal is outside the service cell.

[0094] Scenario 2: The relay terminal and the remote terminal are in the same service cell.

[0095] Scenario 3: The relay terminal and the remote terminal are in different service cells.

[0096] For L3 relay, after the remote terminal establishes a connection to a network using the relay terminal, the relay terminal and the remote terminal Petition 870250099585, dated 10 / 30 / 2025, page 35 / 87 29 / 73 can be in the same cell or in different cells. For L2 relay, after the remote terminal establishes a connection to a network using the relay terminal, both the relay terminal and the remote device are controlled by a relay terminal service cell. Furthermore, before the remote terminal establishes a connection with the relay terminal, the relay terminal device and the remote terminal can be in the same cell or in different cells.

[0097] It should be understood that when the relay terminal provides a network connection service to the remote terminal, the relay terminal's service cell can also be considered a service cell of the remote terminal.

[0098] A discontinuous reception (DRX) mechanism was introduced in the 3rd Generation Partnership Project (3GPP) to save power for a new radio (NR) terminal device. The terminal device can monitor a physical downlink control channel (PDCCH) based on the DRX mechanism. When the DRX mechanism is configured for the terminal device, the terminal device cyclically enters sleep mode at some point. In sleep mode, the terminal device does not need to monitor the PDCCH. When the terminal device needs to monitor the PDCCH, the terminal device wakes up from sleep mode to reduce power consumption. DRX is used as an example for the description below. In different communication systems, DRX may be replaced by another name.

[0099] In addition, to adapt to the low power consumption of the Internet of Things, the XRD mechanism can be extended even further. In this descriptive report, the extended XRD mechanism is called the discontinuous reception mechanism. Petition 870250099585, dated 10 / 30 / 2025, p. 36 / 87 Extended discontinuous reception (eDRX) is a 30 / 73 cycle. It can be understood that eDRX may alternatively be replaced by another name. One cycle of the eDRX mechanism is called an eDRX cycle, and an eDRX cycle is generally longer than an XDR cycle. In the eDRX cycle, the terminal device is in a deep hibernation period most of the time and monitors a paging message only during a paging time window (PTW) based on the DRX mechanism. FIG. 4 is a comparison diagram between an XRD mechanism and an eDRX mechanism. It can be understood that eDRX is used as an example for the description below. In different communication systems, eDRX may alternatively be replaced by another name.

[00100] Paging in NR is used as an example. When a core network or an access network needs to send data to the UE, a paging message is sent to allow a terminal device in an idle Radio Resource Control (RRC) mode or in an inactive mode to enter connected mode. The paging message is sent to the terminal device at a PDSCH resource position, and the PDSCH resource is indicated by a PDCCH encoded with a paging radio network temporary identifier (P-RNTI). In other words, to obtain the paging message, the terminal device must first wake up and cyclically monitor the PDCCH channel encoded with the P-RNTI and then parse the Downlink Control Information (DCI) to obtain a time-frequency position of the PDSCH channel.Finally, the terminal device receives and analyzes the paging message at the time-frequency position of the PDSCH channel.

[00101] In the frequency domain, the frequency domain resource occupied by the paging message is specified by the PDCCH scrambled with the P-RNTI. However, in the domain of Petition 870250099585, dated 10 / 30 / 2025, page 37 / 87 31 / 73 time, the terminal device receives the paging message only on a paging occasion (PO) of a specific radio frame (which can be called a paging frame (PF)) in a terminal device paging cycle. Therefore, gNB needs to send the paging message through an air interface at that moment, and the terminal device can receive it at that moment (i.e., the PO).

[00102] It can be understood that the PF is a radio frame, and a single PF can include one or more POs. The PO is a set of PDCCH monitoring occasions and can include a plurality of slots, subframes, or symbols. Within the PO, there may be a PDCCH that is scrambled with a PRNTI and indicates a paging message. When XRD is used, the terminal device only needs to detect one PO in each XRD cycle. In other words, for each terminal device, gNB can send the paging message in only one PO in each paging cycle. Therefore, the XRD cycle and the paging cycle completely overlap in the time domain. In this descriptive report, the XRD cycle and the paging cycle can be considered as the same concept.

[00103] In the time domain, the terminal device attempts to receive the paging message at a specific PO of a specific PF frame in the paging cycle. gNB needs to send the paging message over the air interface at this time so that the terminal device can receive it at this time.

[00104] NR paging includes core network paging (CN paging) and access network paging (RAN paging). CN paging is initiated by the core network and can be performed on an idle or inactive terminal device. RAN paging is initiated from one side of the RAN and is performed only on an inactive terminal device.

[00105] In the retransmission scenario, when the network Petition 870250099585, dated 10 / 30 / 2025, page 38 / 87 32 / 73 (including the core network and / or the access network) page to the remote terminal. After the network sends a paging message in a paging cycle from the remote terminal, the relay device needs to receive the paging message and forward it to the remote terminal. In this case, the remote terminal needs to provide information related to the remote terminal's paging cycle (the information may be the remote terminal's paging cycle or another parameter used to determine the remote terminal's paging cycle) to the relay terminal so that it can monitor the paging message when the remote terminal's paging cycle arrives.

[00106] For example, a method in which the remote terminal sends information related to the paging cycle to the relay terminal includes:

[00107] 1. If the remote terminal does not store valid versions of one or more required System Information Blocks (SIBs) before the remote terminal sends a message to the relay terminal RemoteUEInformationSidelink (RemoteUEInformationSidelink) is used to request the SIB; the RemoteUEInformationSidelink message includes slRequestedSIB-List to indicate the SIB or SIBs requested by the remote terminal.

[00108] 2. If the remote terminal has not previously sent an sl-PagingInfo-RemoteUE (sl-PagingInfo-RemoteUE) information element to the relay terminal in the RemoteUEInformationSidelink message, the sl-PagingInfo-RemoteUE information element will be set as follows:

[00109] (1) If the remote terminal is in RRC_IDLE mode, an sl-PagingIdentityRemoteUE information element includes a temporary ng-5G-serving Mobile Subscriber Identity (ng5G-S-TMSI). Petition 870250099585, dated 10 / 30 / 2025, page 39 / 87 33 / 73

[00110] If a higher layer configures a specific DRX cycle for the remote endpoint, sl-PagingCycleRemoteUE will be set to the specific DRX cycle configured by the higher layer for the remote endpoint.

[00111] (2) Otherwise, if the remote terminal is in RRC_inactive mode, sl-PagingIdentityRemoteUE includes an ng-5G-S-TMSI and a full inactive-radio network temporary identifier (Full inactive-radio network temporary identifier, full I-RNTI).

[00112] If a top layer configures a specific DRX cycle for the remote endpoint, sl-PagingCycleRemoteUE will be set to the minimum value of the specific DRX cycle (which may be the specific DRX cycle configured by the top layer or a specific DRX cycle configured by the RRC for the remote endpoint) of the remote endpoint. Otherwise, slPagingCycleRemoteUE will be set to the specific DRX cycle configured by the RRC for the remote endpoint.

[00113] 3. The RemoteUEInformationSidelink message is sent to a lower layer for transmission.

[00114] It can be learned that when the remote terminal sends information related to the paging cycle to the relay terminal (for example, a cycle value included in slPagingCycleRemoteUE), only the case where the remote terminal supports the DRX mechanism is considered, and the case where the remote terminal supports the eDRX mechanism is not considered. When the remote terminal supports the eDRX mechanism, the reliability of the relay service provided by the relay terminal to the remote terminal is low and the terminal's power consumption is high.

[00115] In view of this, technical solutions are provided in the modalities of this application. When the remote terminal supports the eDRX mechanism, at least one parameter can be sent to the relay terminal based on information (e.g., Petition 870250099585, dated 10 / 30 / 2025, page 40 / 87 34 / 73 an eDRX cycle and / or a PTW) related to the remote terminal's eDRX mechanism, so that the relay terminal can provide the remote terminal with a relay service that matches the eDRX mechanism. This further improves the reliability of the relay function and reduces the terminal's power consumption.

[00116] FIG. 5 is a flowchart of a communication method according to an embodiment of this application. An example is used in which the method is applied to the scenario shown in FIG. 1. It can be understood that this application is described using an example in which a first terminal and a second terminal are used as execution bodies of an interaction scheme. However, the execution bodies of the interaction scheme are not limited in this application. For example, the first terminal in the method provided in this application may be a chip, a chip system, or a processor used in the first terminal, or it may be a logic node, a logic module, or software that may implement all or some functions of the first terminal. The second terminal in the method provided in this application may alternatively be a chip, a chip system, or a processor used in the second terminal, or it may be a logic node, a logic module, or software that may implement all or some functions of the second terminal.

[00117] S502: The first terminal sends the first information, where the first information includes at least one parameter. Similarly, the second terminal receives the first information from the first terminal.

[00118] The second terminal provides a relay service to the first terminal. In one possible way, the first terminal is a remote terminal and the second terminal is a relay terminal. For example, the second terminal could be terminal device 101 in the communication system shown in FIG. 1, and the first terminal could be terminal device 102 in the communication system shown in FIG. 1. The Petition 870250099585, dated 10 / 30 / 2025, page 41 / 87 35 / 73 second terminal can provide a U2N relay service to the first terminal.

[00119] Optionally, the first piece of information also includes a paging identifier, and the paging identifier indicates that a network pages the first terminal.

[00120] Optionally, the method additionally includes S501: The first terminal determines the first information. Optionally, S501 is performed before S502.

[00121] The first piece of information includes at least one parameter, and that at least one parameter is related to the second piece of information. For example, the first terminal determines at least one parameter based on the second piece of information.

[00122] Optionally, the method additionally includes S503: The second terminal determines a cycle in which the network pages the first terminal. For example, the second terminal determines the second cycle information based on the first information and, based on that information, determines the cycle in which the network sends a pager message to the first terminal. Optionally, S503 is performed after S502.

[00123] In FIG. 5, optional steps are identified by dashed lines.

[00124] In the modalities of this request, the first cycle information is configured for the first terminal, and the first cycle information indicates an eDRX cycle. The first cycle information may specifically be the eDRX cycle (for example, a cycle value indicating a time period, such as N radio frames, where N is a positive integer), or it may be another parameter used to determine the eDRX cycle. This is not limited to this request. For ease of description, in this request, descriptions similar to "the first cycle information is configured for the first terminal" may also be replaced by descriptions of "the eDRX cycle is configured for the first terminal." Petition 870250099585, dated 10 / 30 / 2025, p. 42 / 87 36 / 73

[00125] It can be understood that, in this request, configure can be replaced by other descriptions, for example, have and store.

[00126] In one possible way, the configuration of the first cycle information for the first terminal means that the network configures the first cycle information for the first terminal. For example, the network sends the first cycle information to the first terminal, and the first terminal receives the first cycle information; or the network sends indication information of the first cycle information to the first terminal, and the first terminal receives the indication information and determines the first cycle information based on the indication information. The network may send the first cycle information or the indication information of the first cycle information to the first terminal using the second terminal. It should be understood that the way the network configures the first cycle information for the first terminal here is merely an example. In fact, there may be another way of configuring it.

[00127] There may be one or more types of eDRX cycles. In the embodiments of this application, an example is mainly used where there is only one type of eDRX cycle. Therefore, the type of eDRX cycle can also be replaced by a number of eDRX cycles, i.e., there may be one or more eDRX cycles. For example, the eDRX cycle may include a first eDRX cycle and / or a second eDRX cycle. The first eDRX cycle is configured by an upper layer (i.e., a core network) to the first terminal, and the second eDRX cycle is configured by an RRC layer (i.e., an access network) to the first terminal. Consequently, the first cycle information may include the first indication information and / or the second indication information, the first indication information indicates the first eDRX cycle and the second indication information indicates the second eDRX cycle. Optionally, the Petition 870250099585, dated 10 / 30 / 2025, p. 43 / 87 37 / 73 The first indication information is the first eDRX cycle and the second indication information is the second eDRX cycle. To facilitate the description, the following example uses an instance where the first indication information is the first eDRX cycle and the second indication information is the second eDRX cycle.

[00128] In embodiments of this application, at least one parameter is used to determine the second cycle information (for example, the second terminal determines the second cycle information based on at least one parameter in S503). The second cycle information indicates the cycle in which the network pages to the first terminal (the cycle is called the paging cycle, for short), and the cycle in which the network pages to the first terminal may include a cycle in which the access network pages to the first terminal and / or a cycle in which the central network pages to the first terminal.

[00129] In some forms of this request, at least one parameter is related to the second piece of information. For example, the first terminal determines at least one parameter based on the second piece of information.

[00130] The second piece of information includes at least one of the following: partial information or all of the information (e.g., the first indication information and / or the second indication information) in the first cycle information and a PTW from the first terminal.

[00131] In embodiments of this application, the first terminal may determine the first information based on at least one of the following: boundary information, eDRX information, DRX information, PTW information, and RRC mode information. In other words, the second information may specifically include at least one of the following: boundary information, eDRX information, DRX information, PTW information, and RRC mode information.

[00132] The limit information indicates a first limit, and the first limit is a maximum value within a range of values. Petition 870250099585, dated 10 / 30 / 2025, p. 44 / 87 38 / 73 of an eDRX cycle.

[00133] The eDRX cycle information indicates the eDRX cycle of the first terminal.

[00134] The XRD information indicates an XRD cycle from the first terminal.

[00135] PTW information indicates the PTW of the first terminal.

[00136] The RRC mode information indicates an RRC mode for the first terminal.

[00137] In a possible design, the first terminal determines at least one parameter in the initial information based on the limit information and the eDRX information.

[00138] Optionally, the first terminal determines at least one parameter based on a value relationship between the first limit and the eDRX cycle of the first terminal. For example, if any eDRX cycle of the first terminal is less than or equal to the first limit, at least one parameter is determined based on any extended discontinuous reception cycle, where the second piece of information includes any eDRX cycle. If at least one eDRX cycle of the first terminal exceeds the first limit, at least one parameter will be determined based on the DRX cycle of the first terminal and / or a standard DRX cycle, where the second piece of information includes the PTW of the first terminal, and further includes the DRX cycle of the first terminal or the standard DRX cycle. In other words, if an eDRX cycle that does not exceed the first limit is configured for the first terminal, the eDRX cycle can be used to determine at least one parameter.If an eDRX cycle that exceeds the first limit is configured for the first terminal, PTW can be used to determine at least one parameter.

[00139] For example, when an eXDR cycle indicated by any information in the first cycle does not exceed the first limit, the second includes any information. In other words, if an eXDR cycle that does not exceed the first limit is Petition 870250099585, dated 10 / 30 / 2025, p. 45 / 87 39 / 73 configured for the first terminal, the eDRX cycle that does not exceed the first limit can be used to determine at least one parameter. For example, the first terminal can determine at least one parameter based on the eDRX cycle that does not exceed the first limit.

[00140] When an eDRX cycle indicated by at least one piece of information in the first cycle information exceeds the first limit, the second piece of information includes the PTW. In other words, if an eDRX cycle that exceeds the first limit is configured for the first terminal, the PTW can be used to determine at least one parameter. For example, the first terminal can determine at least one parameter based on the PTW.

[00141] The first limit is a maximum value in a set of candidate parameters used to configure the cycle in which the network sends paging messages to the first terminal. For example, the first limit is a maximum paging cycle specified in a protocol or supported by a communication system. For example, the first limit is 1,024 radio frames. It is understood that the first limit here is only an example and is not limited to 1,024 radio frames.

[00142] It can be understood that, in embodiments of this application, descriptions similar to the first terminal determines at least one parameter based on the eDRX cycle that does not exceed the first limit mean that the first terminal can also determine at least one parameter based on another parameter, for example, the first terminal can perform the determination based on the eDRX cycle that does not exceed the first limit and another parameter (for example, a following eDRX cycle) of the eDRX cycle that does not exceed the first limit.

[00143] In a possible design, the first terminal can determine at least one parameter in the initial information based on eDRX information and DRX information.

[00144] For example, the eDRX cycle of the first terminal Petition 870250099585, dated 10 / 30 / 2025, p. 46 / 87 40 / 73 includes the eDRX cycle configured by the upper layer and / or the eDRX cycle configured by the RRC layer for the first terminal, and the DRX cycle configured for the first terminal includes an XDR cycle configured by the upper layer and / or an XDR cycle configured by the RRC layer for the first terminal.

[00145] Optionally, if the upper layer does not configure the eDRX cycle for the first terminal, at least one parameter will be determined based on the DRX cycle configured by the upper layer for the first terminal and / or the default DRX cycle, where the second piece of information includes a PTW configured by the upper layer for the first terminal and also includes the DRX cycle configured by the upper layer for the first terminal and / or the default DRX cycle; and / or if the RRC layer does not configure the eDRX cycle for the first terminal, at least one parameter will be determined based on the DRX cycle configured by the RRC layer for the first terminal and / or the default DRX cycle, where the second piece of information includes a PTW configured by the RRC layer for the first terminal and also includes the DRX cycle configured by the RRC layer for the first terminal and / or the default DRX cycle.In other words, if an eDRX cycle that does not exceed the first limit is configured for the first terminal, the eDRX cycle can be used to determine at least one parameter. If an eDRX cycle that exceeds the first limit is configured for the first terminal, the PTW, the DRX cycle, and / or the standard DRX cycle can be used to determine at least one parameter.

[00146] For example, the second piece of information also includes third cycle information, and the third cycle information indicates a discontinuous XRD reception cycle. The third cycle information may specifically be the XRD cycle (for example, a cycle value indicating a time period, such as M radio frames, where M is a positive integer), or Petition 870250099585, dated 10 / 30 / 2025, p. 47 / 87 41 / 73 can be another parameter used to determine the XRD cycle. This is not limited to this request. For ease of description, in this request, descriptions similar to "the third cycle information is configured for the first terminal" can also be replaced by descriptions of "the XRD cycle is configured for the first terminal".

[00147] There may be one or more types of XRD cycles. This is not limited to this application. In some embodiments of this application, an example is primarily used where there is only one type of XRD cycle. Therefore, the type of XRD cycle may also be replaced by a number of XRD cycles, i.e., there may be one or more XRD cycles. For example, the XRD cycle may include at least one of a first XRD cycle, a second XRD cycle, and / or a third XRD cycle. The first cycle of DRX is configured by the upper layer (i.e., the core network) for the first terminal. The second XRD loop is configured by the RRC layer (i.e., the access network) for the first terminal. The third XRD loop is the standard XRD loop, for example, an XRD loop configured in a SIB. Correspondingly, the third loop information may include at least one of a third indication information, a fourth indication information, and / or a fifth indication information. The third indication information indicates the first XRD loop, the fourth indication information indicates the second XRD loop, and the fifth indication information indicates the third XRD loop. Optionally, the third indication information is the first XRD loop, the fourth indication information is the second XRD loop, and the fifth indication information is the third XRD loop.To facilitate the description, an example is used below in which the third indication is the first XRD cycle, the fourth indication is the second XRD cycle, and the fifth indication is the third XRD cycle. Petition 870250099585, dated 10 / 30 / 2025, p. 48 / 87 42 / 73

[00148] When the eDRX cycle (i.e., the first eDRX) configured by the upper layer for the first terminal exceeds the first limit, or the upper layer does not configure the eDRX cycle for the first terminal, the second information includes the third indication information and / or the fifth indication information. For example, when the eDRX cycle configured by the upper layer for the first terminal exceeds the first limit, or the upper layer does not configure the eDRX cycle for the first terminal, the first terminal may not determine at least one parameter based on the eDRX cycle configured by the upper layer for the first terminal. In this case, the first terminal may determine at least one parameter based on the default XRD cycle (e.g., the third XRD cycle).Alternatively, if the upper layer configures the XRD cycle (i.e., the first XRD cycle) for the first terminal, the first terminal may still determine at least one parameter based on the XRD cycle configured by the upper layer for the first terminal and / or the default XRD cycle.

[00149] When the eDRX cycle configured by the RRC layer for the first terminal exceeds the first limit, or the RRC layer does not configure the eDRX cycle for the first terminal, the second information includes the second DRX cycle and / or the third DRX cycle. For example, when the eDRX cycle configured by the RRC layer for the first terminal exceeds the first limit, or the upper layer does not configure the eDRX cycle for the first terminal, the first terminal may not determine at least one parameter based on the eDRX cycle configured by the RRC layer for the first terminal. In this case, the first terminal may determine at least one parameter based on the default XRD cycle (e.g., the third XRD cycle). Alternatively, if the RRC layer configures the XRD cycle (i.e., the second XRD cycle) for the first terminal, the first terminal may still determine... Petition 870250099585, dated 10 / 30 / 2025, p. 49 / 87 43 / 73 or at least one parameter based on the XRD cycle configured by the RRC layer for the first terminal and / or the default XRD cycle.

[00150] In one possible design, the first terminal may alternatively determine at least one parameter in the first information based on the RRC mode information. Optionally, if the RRC mode is an idle RRC mode, at least one parameter is determined based on the eDRX cycle configured by the upper layer for the first terminal; or if the mode of For an inactive RRC mode, at least one parameter is determined based on the eDRX cycle configured by the upper layer and / or the eDRX cycle configured by the RRC layer for the first endpoint. When the first endpoint is in different RRC modes, network devices that initiate paging for the first endpoint may be different. Therefore, the first endpoint determines, based on the RRC mode, a parameter provided to the second endpoint, to help improve the reliability of the second endpoint's determination of a paging cycle.

[00151] For example, the second piece of information may also include RRC mode information, RRC mode information indicates the RRC mode of the first terminal, and the RRC mode of the first terminal may be an idle RRC mode or an inactive RRC mode.

[00152] When the RRC mode of the first terminal is inactive RRC mode, the second information includes cycle information configured by the upper layer for the first terminal, and the cycle information configured by the upper layer for the first terminal indicates an eDRX cycle and / or an XRD cycle. For example, when the RRC mode of the first terminal is inactive RRC mode, the first terminal can determine at least one parameter based on the eDRX cycle and / or the DRX cycle configured by the upper layer. Petition 870250099585, dated 10 / 30 / 2025, p. 50 / 87 44 / 73

[00153] When the RRC mode of the first terminal is inactive RRC mode, the second information includes the cycle information configured by the upper layer and / or the cycle information configured by the RRC layer for the first terminal, and the cycle information configured by the RRC layer for the first terminal indicates an eDRX cycle and / or an XDR cycle. For example, when the RRC mode of the first terminal is inactive RRC mode, the first terminal can determine at least one parameter based on the eDRX cycle and / or the XDR cycle configured by the upper layer and / or the eDRX cycle and / or the XDR cycle configured by the RRC layer.

[00154] The core network can initiate paging to the terminal in RRC idle mode and the terminal in RRC inactive mode, and the access network initiates paging to the terminal in RRC inactive mode. Therefore, when the RRC mode of the first terminal is RRC idle mode, the first terminal can determine at least one parameter based on the eDRX cycle and / or the DRX cycle configured by the upper layer. When the RRC mode of the first terminal is RRC inactive mode, the first terminal can determine at least one parameter based on the eDRX cycle and / or the DRX cycle configured by the upper layer and / or the eDRX cycle and / or the DRX cycle configured by the RRC layer.

[00155] In a possible design, the first terminal can determine at least one parameter in the first information based on the PTW information. Optionally, the first terminal's PTW includes the PTWs configured by the upper layer and the RRC layer for the first terminal. Determining at least one parameter in the first information based on the PTW information includes: determining at least one parameter based on a value relationship between the PTW configured by the upper layer for the first terminal and the PTW configured by the RRC layer for the first terminal; or determining at least one parameter Petition 870250099585, dated 10 / 30 / 2025, page 51 / 87 45 / 73 based on an overlap mode between the PTW configured by the upper layer for the first terminal and the PTW configured by the RRC layer for the first terminal. For example, determining at least one parameter based on the value ratio between the PTW configured by the upper layer for the first terminal and the PTW configured by the RRC layer for the first terminal includes: if the PTW configured by the upper layer for the first terminal is greater than the PTW configured by the RRC layer for the first terminal, determining at least one parameter based on the DRX cycle configured by the upper layer for the first terminal and / or the default DRX cycle, where the second piece of information includes the PTW configured by the upper layer for the first terminal and also includes the DRX cycle configured by the upper layer for the first terminal and / or the default DRX cycle;or if the PTW configured by the upper layer for the first terminal is less than the PTW configured by the RRC layer for the first terminal, determine at least one parameter based on the DRX cycle configured by the RRC layer for the first terminal and / or the default DRX cycle, where the second piece of information includes the PTW configured by the RRC layer for the first terminal and also includes the DRX cycle configured by the RRC layer for the first terminal and / or the default DRX cycle.

[00156] For example, determining at least one parameter based on the overlap mode between the PTW configured by the upper layer for the first terminal and the PTW configured by the RRC layer for the first terminal includes: if the PTW configured by the upper layer for the first terminal does not overlap with the PTW configured by the RRC layer for the first terminal, determining at least one parameter based on the DRX cycles configured by the upper layer and the RRC layer for the first terminal and / or the default DRX cycle, where the second piece of information includes the configured PTWs. Petition 870250099585, dated 10 / 30 / 2025, page 52 / 87 46 / 73 by the top layer and the RRC layer for the first terminal, and also includes the XRD cycles configured by the top layer and the RRC layer for the first terminal and / or the default XRD cycle; or if there is an overlapping part and a non-overlapping part between the PTW configured by the top layer for the first terminal and the PTW configured by the RRC layer for the first terminal, for the overlapping part, determine at least one parameter based on the DRX cycle configured by the top layer for the first terminal, the DRX cycle configured by the RRC layer for the first terminal and the default DRX cycle, wherein the second information includes the PTWs configured by the top layer and the RRC layer for the first terminal and also includes the DRX cycle configured by the top layer for the first terminal, the DRX cycle configured by the RRC layer for the first terminal and the default DRX cycle;and for the non-overlapping portion, determine at least one parameter based on the standard XDR cycle and an XDR cycle at the larger PTW configured by the top layer for the first terminal and the PTW configured by the RRC layer for the first terminal, where the second piece of information includes the larger PTW, the XDR cycle at the larger PTW, and the standard XDR cycle.

[00157] In one possible implementation, the fact that at least one parameter is related to the second piece of information includes, but is not limited to, at least one of the following implementations:

[00158] Implementation 1: At least one parameter includes partial information or all of the information in the second piece of information.

[00159] For example, the first terminal can send partial or all of the information from the second terminal to the second terminal. For example, the first terminal can send one or more of the following: PTW, the first indication information (e.g., the first eDRX cycle), the second Petition 870250099585, dated 10 / 30 / 2025, p. 53 / 87 47 / 73 indication information (e.g., the second eDRX cycle), the third indication information (e.g., the first XRD cycle), the fourth indication information (e.g., the second XRD cycle), the fifth indication information (e.g., the third XRD cycle), and similar information for the second terminal.

[00160] Implementation 2: At least one parameter includes a statistical value of partial or complete information in the second piece of information.

[00161] For example, the statistical value of partial or complete information in the second information is a minimum value of partial or complete information in the second information. For example, the first terminal may send a minimum value of at least two of the following indications: first indication (e.g., first eDRX cycle), second indication (e.g., second eDRX cycle), third indication (e.g., first DRX cycle), fourth indication (e.g., second DRX cycle), fifth indication (e.g., third DRX cycle), and similar indications to the second terminal.

[00162] For the specific content of the second piece of information, please refer to the previous implementations.

[00163] It should be understood that the implementations in this application may be implemented separately or in combination with each other. This is not limited to this application.

[00164] Here is an example of a possible combination:

[00165] The first terminal is in RRC idle mode or RRC inactive mode, and the eDRX cycle is configured for the first terminal. The first terminal can determine, based on different cases, the parameter to be sent to the second terminal. The details are as follows:

[00166] 1. When the first terminal is in RRC idle mode, only the core network initiates paging. The upper layer configures the eDRX cycle (represented by T_(eDRX_CN)) for the Petition 870250099585, dated 10 / 30 / 2025, p. 54 / 87 48 / 73 first terminal:

[00167] (1) If T_(eDRX_CN) does not exceed 1024 radio frames, the first terminal sends T_(eDRX_CN) to the second terminal.

[00168] (2) If T_(eDRX_CN) exceeds 1024 radio frames and the upper layer configures the XRD cycle (represented by T_(DRX_CN)) for the first terminal, the first terminal sends PTW and T_(DRX_CN) to the second terminal. Optionally, the first terminal may additionally send to the second terminal the standard XRD cycle configured in the SIB.

[00169] 2. When the first terminal is in idle mode In the RRC, both the core network and the access network initiate paging, and the eDRX cycle of the first endpoint may include the eDRX cycle (represented by T_(eDRX_CN)) configured by the upper layer and / or the eDRX cycle configured by the RRC layer (represented by T_(eDRX_RAN)):

[00170] (1) If the upper layer sets T_(eDRX_CN) for the first terminal and the RRC layer sets T_(eDRX_RAN) for the first terminal, and neither T_(eDRX_RAN) nor T_(eDRX_CN) exceed 1024 radio frames, the first terminal will send a lower value in T_(eDRX_RAN) and T_(eDRX_CN) to the second terminal.

[00171] (2) If the upper layer sets T_(eDRX_CN) for the first terminal, T_(eDRX_CN) does not exceed 1024 radio frames, the RRC does not set T_(eDRX_RAN) for the first terminal and the RRC layer sets the DRX cycle (represented by T_(DRX_RAN)) for the first terminal, the first terminal may send a lower value in T_(eDRX_CN) and T_(DRX_RAN) to the second terminal, or the first terminal may send T_(eDRX_CN) and T_(DRX_RAN) to the second terminal.

[00172] (3) The upper layer configures T_(eDRX_CN) for the first terminal, and T_(eDRX_CN) exceeds 1024 radio frames:

[00173] A. If the RRC layer does not configure T_(eDRX_RAN) for the first terminal, the RRC layer configures T_(DRX_RAN) for the first terminal and / or the upper layer configures Petition 870250099585, dated 10 / 30 / 2025, p. 55 / 87 49 / 73 T_(DRX_CN) to the first terminal, the first terminal can send PTW, T_(DRX_RAN) and / or T_(DRX_CN) to the second terminal. Alternatively, if the RRC layer does not set T_(eDRX_RAN) for the first terminal, and the upper layer sets T_(DRX_CN) for the first terminal, the first terminal may send PTW and a lower value in T_(DRX_RAN) and T_(DRX_CN) to the second terminal.

[00174] B. If the RRC layer configures T_(eDRX_RAN) for the first terminal, T_(eDRX_RAN) does not exceed 1024 radio frames, and the upper layer configures T_(DRX_CN) for the first terminal, the first terminal may send PTW, T_(DRX_CN) and / or T_(eDRX_RAN) to the second terminal; or the first terminal may send PTW, T_(eDRX_RAN) and a smaller value in T_(DRX_CN) and T_(eDRX_RAN) to the second terminal.

[00175] C. The RRC layer configures T_(eDRX_RAN) for the first terminal, and T_(eDRX_RAN) exceeds 1024 radio frames. C includes C1 and C2:

[00176] C1. The PTW (represented by a CN PTW below) configured by the core network for the first terminal and the PTW (represented by a RAN PTW below) configured by the RAN for the first terminal do not overlap, i.e., they do not overlap in the time domain. The first terminal can send the lowest value in the CN PTW, the DRX cycle configured by the CN in the CN PTW and a standard DRX cycle in a SIB message, and the lowest value in the RAN PTW, the DRX cycle configured by the RAN in the RAN PTW and the standard DRX cycle in the SIB message to the first terminal UE. The lowest value in CN PTW, the DRX cycle configured by CN in CN PTW, and the default DRX cycle in the SIB message are used by the second terminal to determine a cycle in which CN pages the first terminal, and the lowest value in RAN PTW, the DRX cycle configured by RAN in RAN PTW, and the default DRX cycle in the SIB message are used by the second terminal. Petition 870250099585, dated 10 / 30 / 2025, pp. 56 / 87 50 / 73 to determine a cycle in which the RAN pages the first terminal.

[00177] C2. No distinction is made between CN PTW and RAN PTW, i.e., whether CN PTW overlaps with RAN PTW in the time domain, as shown in FIG. 6.

[00178] In one possible solution, an overlapping part and a non-overlapping part are distinguished.

[00179] For the overlapping portion, the first terminal sends a lower value in T_(DRX_CN), T_(DRX_RAN) and the standard XRD cycle to the second terminal, so that the second terminal determines a cycle in which the network pages the first terminal in the overlapping portion.

[00180] For the non-overlapping portion, the first terminal chooses to send a smaller value in a DRX cycle in a longer PTW and in the standard DRX cycle. For example, if the CN PTW is greater than the RAN PTW, the first terminal sends a smaller value in the DRX cycle, configured by the CN, in the CN PTW and the DRX value in the SIB message to the second terminal. If the RAN PTW is greater than the CN PTW, the first terminal sends a smaller value in the DRX cycle, configured by the RAN, in the RAN PTW and the DRX value in the SIB message to the second terminal.

[00181] In another possible solution, there is no distinction between CN PTW overlap and RAN PTW overlap. If the CN PTW is larger, the first terminal sends a smaller value in the DRX cycle, configured by the CN, in the CN PTW and the DRX value in the SIB message to the second terminal. If the RAN PTW is larger, the first terminal sends a smaller value in the DRX cycle, configured by the RAN, in the RAN PTW and the DRX value in the SIB message to the second terminal.

[00182] In addition, the first terminal device needs to send the PTW to the second terminal device. Specifically, if the CN PTW is the same as the RAN PTW, the first terminal device can choose to send either the CN PTW or the RAN PTW to the second terminal device. Otherwise, the first Petition 870250099585, dated 10 / 30 / 2025, page 57 / 87 51 / 73 terminal device sends both the CN PTW and the RAN PTW to the second terminal device.

[00183] It can be understood that, in FIG. 6, an example is used where the CN PTW is greater than the RAN PTW. This is not limited to the same.

[00184] It can be understood that the above is just one example of a possible combination, and that in fact there are other ways of combining.

[00185] For example, the first terminal sends at least one parameter through a PC5 interface, and the second terminal receives at least one parameter through the PC5 interface.

[00186] For example, the first terminal has a RemoteUEInformationSidelink message that carries at least one parameter, specifically, at least one parameter is included in an slPagingIdentityRemoteUE information element of the RemoteUEInformationSidelink message.

[00187] It can be understood that, in modalities of this request, the cycle in which the network pages to the first terminal is a paging cycle on the terminal side, and is a cycle in which the first terminal and / or the second terminal receive the paging message sent by the network to the first terminal, that is, the first terminal and the second terminal receive the paging message in the cycle. The cycle may be the same as or different from a paging cycle on the network side (i.e., an actual cycle in which the network sends the paging message). For example, the paging cycle on the network side and the paging cycle on the terminal side may be in a multiple integer relationship.

[00188] It can be understood that, if at least one parameter is different, the second terminal determines the second loop information in different ways. For example, if at least one parameter includes a plurality of loops, the second terminal can determine a minimum loop in the plurality of loops as the paging loop of the first terminal. For example, if by Petition 870250099585, dated 10 / 30 / 2025, p. 58 / 87 52 / 73 minus one parameter includes only one cycle, the second terminal directly determines the cycle as the paging cycle of the first terminal, or compares the cycle with the standard XRD cycle in the SIB, and determines, as the paging cycle of the first terminal, a smaller value in the cycle and the standard XRD cycle in the SIB.

[00189] Optionally, when an eDRX cycle or XRD cycle is configured for the second terminal, the second terminal can further determine the second cycle information based on at least one parameter provided by the first terminal and the eDRX cycle and / or XRD cycle of the second terminal. For example, the at least one parameter includes at least one cycle (e.g., the eDRX cycle and / or XRD cycle of the first terminal). The second terminal compares the at least one cycle with the eDRX cycle and / or XRD cycle of the second terminal and determines the smaller cycle as the paging cycle of both the first and second terminals. Therefore, it is ensured that the second terminal can not only receive the paging message from the first terminal but also receive the paging message from the second terminal.

[00190] Certainly, the above is just one example, and a real way in which the second terminal determines the second cycle information is not limited to this.

[00191] Optionally, after step S503 (that is, after the second terminal determines the second cycle information), the method may also include steps S504 and S505.

[00192] S504: The network device (for example, network device 103 in FIG. 1) sends a paging message corresponding to the first terminal in the first terminal's paging cycle, and the second terminal receives the paging message from the network (the access network and / or the core network) in the first terminal's paging cycle.

[00193] S505: The second terminal sends the paging message to the first terminal. Petition 870250099585, dated 10 / 30 / 2025, page 59 / 87 53 / 73

[00194] In previous solutions, when the first terminal supports an eDRX mechanism, the first terminal can determine, based on information (e.g., an eDRX cycle and a PTW) related to the eDRX mechanism, at least one parameter to be sent to the second terminal, so that the paging cycle determined by the second terminal based on at least one parameter can adapt to the eDRX mechanism of the first terminal. This can improve the reliability of a relay function and reduce the terminal's power consumption.

[00195] In one possible implementation, before sending at least one parameter (i.e., S502), the first terminal may first determine whether the capacity information of the second terminal and the capacity information of a service cell of the first terminal meet a predefined condition. When the capacity information of the second terminal and the capacity information of the service cell of the first terminal meet the predefined condition, the first terminal sends at least one parameter to the second terminal. If the capacity information of the second terminal and the capacity information of the service cell of the first terminal do not meet the predefined condition, the first terminal may not send at least one parameter to the second terminal.Alternatively, before determining at least one parameter (i.e., S501), the first terminal can first determine if the capacity information of the second terminal and the capacity information of the service cell of the first terminal meet the predefined condition. When the capacity information of the second terminal and the capacity information of the service cell of the first terminal meet the predefined condition, the parameter to be sent to the second terminal is determined based on the method in S501. If the capacity information of the second terminal and the capacity information of the service cell of the first terminal do not meet the predefined condition, the first... Petition 870250099585, dated 10 / 30 / 2025, pp. 60 / 87 Terminal 54 / 73 determines, based on another method (for example, the method in which the remote terminal sends, to the relay terminal, the information related to the paging cycle described before the mode in FIG. 5) instead of the method in S501, the parameter to be sent to the second terminal.

[00196] The second terminal capability information indicates whether or not the second terminal supports the eDRX mechanism, the service cell capability information indicates whether or not the service cell supports the eDRX mechanism, and the default condition may include that the second terminal supports the eDRX mechanism and the service cell supports the eDRX mechanism.

[00197] Based on the previous descriptions, when the relay terminal provides a network connection service to the remote terminal, a service cell of the relay terminal can also be considered a service cell of the remote terminal. In some embodiments of this application, the second terminal provides the relay service to the first terminal. Therefore, the service cell of the first terminal described here can also be considered a service cell of the second terminal.

[00198] It can be understood that the first terminal can only run the eDRX mechanism when the first terminal, the second terminal, and the service cell of the first terminal support the eDRX mechanism. If the service cell of the second terminal and / or the service cell of the first terminal support / do not support the eDRX mechanism, the first terminal cannot run it. Therefore, when the capacity information of the second terminal and the capacity information of the service cell of the first terminal meet the predefined condition, the second terminal can determine the paging cycle based on at least one parameter.

[00199] Furthermore, in a real case, for the terminal in Petition 870250099585, dated 10 / 30 / 2025, page 61 / 87 55 / 73 different RRC modes, the service cell capability information may vary. Therefore, whether the service cell supports the eDRX mechanism may specifically include: When the first terminal's RRC mode is RRC idle mode and / or RRC inactive mode, the service cell supports the eDRX mechanism. Correspondingly, when the service cell supports the eDRX mechanism, the first terminal sends at least one parameter. For example, if the service cell supports the eDRX mechanism when the first terminal's RRC mode is RRC idle mode, the first terminal sends at least one parameter when the first terminal is in RRC idle mode. If the service cell supports the eDRX mechanism when the first terminal's RRC mode is RRC inactive mode, the first terminal sends at least one parameter when the first terminal is in RRC inactive mode.

[00200] It can be understood that, before determining whether the capacity information of the second terminal and the capacity information of the service cell of the first terminal meet the predefined condition, the first terminal must first obtain the capacity information of the second terminal and the capacity information of the service cell of the first terminal.

[00201] In one possible example, the second terminal can send the capacity information of the second terminal to the first terminal. For example, the second terminal can send the capacity information of the second terminal to the first terminal when establishing a unicast connection with the first terminal. Alternatively, for example, the first terminal sends a request (the request is used to query the capacity information of the second terminal) to the second terminal. After receiving the request, the second terminal sends the capacity information of the second terminal to the first terminal.

[00202] In another possible example, the network device Petition 870250099585, dated 10 / 30 / 2025, page 62 / 87 Terminal 56 / 73 has a SIB1 message that carries the service cell capacity information. After receiving the SIB1 message, the second terminal sends the SIB1 message to the first terminal. After receiving the SIB1 message, the first terminal determines the service cell capacity information from the SIB message. For example, the SIB1 message includes two fields: eDRX-AllowedIdle-r17 and eDRX-AllowedInactive-r17. The eDRX-AllowedIdle-r17 field indicates whether or not the service cell supports the eDRX mechanism when the first terminal is in RRC inactive mode. The eDRX-AllowedInactive-r17 field indicates whether or not the service cell supports the eDRX mechanism when the first terminal is in RRC inactive mode.

[00203] In the previous implementation, the first terminal determines, based on the capacity information of the second terminal and the capacity information of the service cell of the first terminal, whether to provide the information related to the eDRX mechanism from the first terminal to the second terminal, in order to reduce a waste of transmission resources and further reduce the terminal's energy consumption.

[00204] In one possible implementation, when the capacity information of the second terminal and the capacity information of the service cell of the first terminal meet the predefined condition, the second terminal can send the sixth indication information to the first terminal. The sixth indication information indicates that the first terminal must send at least one parameter (i.e., provide the information related to the eDRX mechanism of the first terminal to the second terminal), or the sixth indication information indicates that the second terminal is capable of receiving, for the first terminal, the paging message sent by the network to the first terminal. After receiving the sixth indication information, the first terminal sends at least one parameter to the second terminal. Alternatively, when the capacity information of the second terminal and the Petition 870250099585, dated 10 / 30 / 2025, pp. 63 / 87 If the 57 / 73 service cell capacity information from the first terminal meets the predefined condition, the second terminal can send the sixth indication information to the first terminal. The sixth indication information indicates that the first terminal must determine, according to the method in S501, the parameter to be sent to the second terminal. After receiving the sixth indication information, the first terminal determines, according to the method in S501, the parameter to be sent to the second terminal.

[00205] For information on the second terminal's capacity, service cell capacity, default conditions, and similar information, please refer to the previous descriptions. Details are not described again in this document.

[00206] When the capacity information of the second terminal and the capacity information of the service cell of the first terminal do not meet the predefined condition, or the second terminal cannot receive, for the first terminal, the paging message sent by the network to the first terminal, the second terminal may not send the sixth indication information. When the first terminal does not receive the sixth indication information, the first terminal does not send at least one parameter to the second terminal or does not determine, according to the method in S501, the parameter provided to the second terminal. Alternatively, when the capacity information of the second terminal and the capacity information of the service cell of the first terminal do not meet the predefined condition, the second terminal may not send the sixth indication information, but send the seventh indication information.The seventh piece of information indicates that the first terminal should not send at least one parameter, or indicates that the first terminal should not determine, according to the method in S501, the parameter provided to the second terminal, or indicates that the second terminal cannot receive, for the first terminal, the paging message sent over the network to the first terminal. Petition 870250099585, dated 10 / 30 / 2025, pp. 64 / 87 58 / 73 Based on the seventh piece of information, the first terminal determines whether to send at least one parameter to the second terminal, or does not determine, according to the method in S501, the parameter provided to the second terminal.

[00207] With this implementation, the waste of transmission resources can be reduced and the terminal's energy consumption can be further reduced. In addition, the complexity of the implementation at the first terminal can be further reduced.

[00208] FIG. 7 is a flowchart of another communication method according to a modality of this application; an example is used in which the method is applied to the scenario shown in FIG. 1. The method includes S601 to S603.

[00209] S602: A first terminal sends initial information, where the initial information includes at least one parameter. Similarly, a second terminal receives the initial information from the first terminal.

[00210] The second terminal provides a relay service to the first terminal, the first cycle information is configured for the first terminal, and the first cycle information indicates an eDRX cycle. For specific implementations of the first terminal, the second terminal, the first cycle information, and similar configurations, see the related descriptions in S501. Details are not described again in this document.

[00211] At least one parameter is related to the eDRX information of the first terminal. For example, at least one parameter is determined based on the eDRX information of the first terminal.

[00212] Optionally, the first piece of information also includes a paging identifier, and the paging identifier indicates that a network pages the first endpoint.

[00213] Optionally, the method additionally includes S601: The first terminal determines the first information based on Petition 870250099585, dated 10 / 30 / 2025, p. 65 / 87 59 / 73 eDRX information from the first terminal, where the first information includes at least one parameter. Optionally, S601 is performed before S602.

[00214] Optionally, the method additionally includes S603: The second terminal determines a cycle in which the network pages the first terminal. For example, the second terminal determines the second cycle information based on the first information and, based on that information, determines the cycle in which the network sends a pager message to the first terminal. Optionally, S603 is performed after S602.

[00215] In FIG. 7, optional steps are identified by dashed lines.

[00216] In this method, the second terminal and / or a service cell of the first terminal (or a service cell of the second terminal) support / do not support an eDRX mechanism. Alternatively, the first terminal cannot determine whether the second terminal and / or a service cell of the first terminal (or a service cell of the second terminal) support / support an eDRX mechanism; for example, the first terminal does not obtain capacity information from the second terminal and / or capacity information from the service cell of the first terminal (or the service cell of the second terminal).

[00217] Whether the second terminal and / or the second terminal's service cell support / do not support the eDRX mechanism includes the following cases:

[00218] 1. The second terminal does not support the eDRX mechanism, and the service cell of the second terminal does support the eDRX mechanism.

[00219] 2. The second terminal does not support the eDRX mechanism, and the service cell of the second terminal does not support the eDRX mechanism.

[00220] 3. The second terminal supports the eDRX mechanism, and the service cell of the second terminal does not support the mechanism. Petition 870250099585, dated 10 / 30 / 2025, pp. 66 / 87 60 / 73 eDRX.

[00221] The fact that the second terminal service cell supports the eDRX mechanism includes: When a second terminal RRC mode is an idle RRC mode and / or an inactive RRC mode, the second terminal service cell supports the eDRX mechanism.

[00222] In some embodiments of this application, the second terminal provides the relay service to the first terminal. Therefore, the service cell of the second terminal can also be considered as the service cell of the first terminal.

[00223] For specific implementations of S602 and S603, see the specific implementations of S502 and S503. Details are not described again in this document.

[00224] In the previous solution, when the second terminal and / or the service cell of the first terminal (or the service cell of the second terminal) do not support the eDRX mechanism, a parameter provided by the first terminal to the second terminal is linked to the eDRX information of the first terminal, so that the relay service provided by the second terminal to the first terminal can adapt to the eDRX mechanism of the first terminal. This improves the reliability of a relay function and reduces the terminal's power consumption.

[00225] In a possible design, the eDRX information from the first terminal indicates an eDRX cycle from the first terminal. Determining the first information based on the eDRX information from the first terminal includes: determining at least one parameter based on the eDRX information from the first terminal and the reference information. The reference information includes at least one of the following: limit information, a first range of values, a second range of values, and RRC mode information. The limit information includes a first limit and / or a second limit. The first range of values ​​is a range of Petition 870250099585, dated 10 / 30 / 2025, pp. 67 / 87 61 / 73 values ​​of an eDRX cycle. The second range of values ​​is a range of values ​​of an XRD cycle. The RRC mode information indicates an RRC mode of the first terminal.

[00226] Optionally, the first limit is a maximum value in the first range of values, and the second limit is a maximum value in the second range of values.

[00227] For example, the first range of values ​​is {rf256, rf512, rf1024}, where rf256, rf512, and rf1024 indicate, respectively, 256 radio frames, 512 radio frames, and 1024 radio frames, and the second range of values ​​is {rf32, rf64, rf128, rf256}, where rf32, rf64, rf128, and rf256 indicate, respectively, 32 radio frames, 64 radio frames, 128 radio frames, and 256 radio frames. The second limit is rf256 and the first limit is rf1024.

[00228] In a possible design, the determination of at least one parameter based on the eDRX information from the first terminal and the reference information includes: determining at least one parameter based on a value relationship between the eDRX cycle indicated by the eDRX information from the first terminal and the limit indicated by the limit information.

[00229] For example, determining at least one parameter based on the value relationship between the eDRX cycle indicated by the eDRX information from the first terminal and the limit indicated by the limit information includes: (1) if the eDRX cycle of the first terminal is less than or equal to the second limit, determine that at least one parameter includes the eDRX cycle of the first terminal; or (2) if the eDRX cycle of the first terminal exceeds the second limit and is less than or equal to the first limit, determine at least one parameter based on an intersection of the first range of values ​​and the second range of values; or (3) if the eDRX cycle of the first terminal exceeds the Petition 870250099585, dated 10 / 30 / 2025, pp. 68 / 87 62 / 73 first limit, determine that at least one parameter includes the XRD loop of the first terminal.

[00230] In a possible project, determining at least one parameter based on the intersection of the first range of values ​​and the second range of values ​​includes: if the intersection of the first range of values ​​and the second range of values ​​includes only one value, determine that at least one parameter includes the value; or if the intersection of the first range of values ​​and the second range of values ​​includes a plurality of values, determine that at least one parameter includes a maximum value in the plurality of values.

[00231] In a possible project, the determination of at least one parameter based on the intersection of the first range of values ​​and the second range of values ​​includes: If the intersection of the first range of values ​​and the second range of values ​​includes only one value, determine that at least one parameter includes the value or the maximum value in the second range of values. For example, if the first range of values ​​is {rf256, rf512, rf1024}, the second range of values ​​is {rf32, rf64, rf128, rf256}, and the intersection includes only one value rf256, then determine that at least one parameter includes the maximum value rf256 in the second range of values ​​(i.e., the value in the intersection). Or, if the intersection of the first range of values ​​and the second range of values ​​is an empty set, determine that at least one parameter includes the maximum value in the second range of values. Or, if the intersection of the first range of values ​​and the second range of values ​​includes a plurality of values, determine that at least one parameter includes a maximum value in the plurality of values.

[00232] In one possible design, the eDRX cycle of the first terminal includes an eDRX cycle configured by a layer Petition 870250099585, dated 10 / 30 / 2025, p. 69 / 87 63 / 73 higher for the first terminal and / or an eDRX cycle configured by an RRC layer for the first terminal. The method further includes: if the eDRX information of the first terminal includes the eDRX cycle configured by the upper layer for the first terminal and the eDRX cycle configured by the RRC layer for the first terminal, determine that the eDRX information of the first terminal indicates a lower value in the eDRX cycle configured by the upper layer for the first terminal and in the eDRX cycle configured by the RRC layer for the first terminal; or if the eDRX information of the first terminal includes the eDRX cycle configured by the upper layer for the first terminal or the eDRX cycle configured by the RRC layer for the first terminal, determine that the eDRX information of the first terminal indicates the eDRX cycle.

[00233] In a possible design, the eDRX cycle of the first terminal includes the eDRX cycle configured by the upper layer for the first terminal and / or the eDRX cycle configured by the RRC layer for the first terminal. Determining at least one parameter based on the eDRX information of the first terminal and the reference information includes: if the RRC mode is an inactive RRC mode, determining at least one parameter based on the eDRX cycle configured by the upper layer for the first terminal; or if the RRC mode is an inactive RRC mode, determining at least one parameter based on the eDRX cycle configured by the upper layer and / or the eDRX cycle configured by the RRC layer for the first terminal.

[00234] It can be understood that the various projects above can be implemented separately or in combination with each other.

[00235] Below is an example of a combination.

[00236] The first terminal is in RRC idle mode or RRC inactive mode, and the eDRX cycle is configured for the first terminal. The first terminal can determine, based on Petition 870250099585, dated 10 / 30 / 2025, pp. 70 / 87 64 / 73 in different cases, the parameter to be sent to the second terminal. The details are as follows:

[00237] 1. When the first terminal is in idle mode In RRC, only one core network initiates paging. The upper layer configures the eDRX cycle (represented by T_(eDRX_CN)) for the first terminal, and T_(eDRX_CN) does not exceed 1024 frames. (1) if T_(eDRX_CN) is greater than or equal to 256 frames, at least one parameter includes a maximum value at an intersection of a range of values ​​for an XDR cycle and a range of values ​​for the eDRX cycle.

[00238] For example, the range of values ​​for the eDRX loop is {rf256, rf512, rf1024}, and the range of values ​​for the loop of XRD is {rf32, rf64, rf128, rf256}.

[00239] (2) If T_(eDRX_CN) is less than 256 frames, at least one parameter includes T_(eDRX_CN).

[00240] 2. When the first terminal is in idle mode In the RRC, both the core network and an access network initiate paging, and the eDRX cycle of the first endpoint may include the eDRX cycle (represented by T_(eDRX_CN)) configured by the upper layer and / or the eDRX cycle configured by the RRC layer (represented by T_(eDRX_RAN)):

[00241] (1) T_(eDRX_CN) and T_(eDRX_RAN) do not exceed 1024 frames:

[00242] A. A smaller value in T_(eDRX_CN) and T_(eDRX_RAN) is greater than or equal to 256 frames, and at least one parameter includes a maximum value in an overlapping part of the DRX cycle value range and the eDRX cycle value range.

[00243] B. The smallest value in T_(eDRX_CN) and T_(eDRX_RAN) is less than 256 frames, and at least one parameter includes min{T_(eDRX_CN), T_(eDRX_RAN)}.

[00244] (2) T_(eDRX_CN) does not exceed 1024 frames and T_(eDRX_RAN) is not configured: at least one parameter includes a smaller value (or a Petition 870250099585, dated 10 / 30 / 2025, pp. 71 / 87 65 / 73 XRD cycle configured by the RRC layer) in the XRD cycle configured by the RRC layer and T_(eDRX_CN). Optionally, if T_(eDRX_CN) is less than an XRD cycle configured by the upper layer, at least one parameter includes T_(eDRX_CN).

[00245] (3) T_(eDRX_CN) exceeds 1024 frames and T_(eDRX_RAN) does not exceed 1024 frames: At least one parameter includes a smaller value (or the XRD cycle configured by the upper layer) in the XRD cycle configured by the upper layer and T_(eDRX_RAN). Optionally, if the XRD cycle configured by the upper layer is smaller than the XRD cycle configured by the upper layer, at least one parameter includes T_(eDRX_RAN).

[00246] (4) T_(eDRX_CN) exceeds 1024 frames and T_(eDRX_RAN) exceeds 1024 frames: The first terminal provides the parameter to the second terminal based on the case where only the remote terminal supports the XRD mechanism as described above.

[00247] It can be understood that the above is just one example of a possible combination, and that in fact there are other ways of combining.

[00248] It can be understood that the methods described in FIGS. 5 to 7 are all applicable to a scenario where the eDRX cycle is configured for the first terminal. If the eDRX cycle is not configured for the first terminal, the first terminal can determine, based on another method (for example, the method where the remote terminal sends the relay terminal the information related to the paging cycle in the mode of FIG. 5), the parameter to be sent to the second terminal.

[00249] The methods provided in the embodiments of this application are described above with reference to the attached drawings. The apparatus provided in the embodiments of this application is described below with reference to the attached drawings. Petition 870250099585, dated 10 / 30 / 2025, p. 72 / 87 66 / 73

[00250] Based on the same technical concept, one embodiment of this application provides a communication device. The device includes modules / units / means configured to perform the methods performed by the first terminal or the second terminal in the previous method embodiments. The modules / units / means can be implemented by software, hardware, or hardware through the execution of corresponding software.

[00251] For example, as shown in FIG. 8, the device may include an interface module 701 and a processing module 702.

[00252] For example, when the device is the first terminal or is located at the first terminal, processing module 702 is configured to determine the first information, where the first information includes at least one parameter. Interface module 701 is configured to send the first information to a second terminal. First cycle information is configured for the first terminal, the first cycle information indicates an eDRX cycle of the first terminal, at least one parameter is used to determine the second cycle information, the second cycle information is used to determine a cycle in which a network pages the first terminal, at least one parameter is related to the second information, and the second information includes at least one of the following: partial information or all information in the first cycle information and a PTW of the first terminal.

[00253] Alternatively, processing module 702 is configured to determine first information based on eDRX information from a first terminal, where the first information includes at least one parameter. Interface module 701 is configured to send the first information to a second terminal, where at least one parameter is used to determine the second cycle information, and the second information Petition 870250099585, dated 10 / 30 / 2025, pp. 73 / 87 The 67 / 73 cycle is used to determine a cycle in which a network pages the first terminal.

[00254] For example, when the device is the second terminal or is located at the second terminal, interface module 701 is configured to: receive the first information, where the first information includes at least one parameter, the first cycle information is configured for a first terminal, the first cycle information indicates an eDRX cycle of the first terminal, at least one parameter is related to the second information, and the second information includes at least one of the following: partial information or all information in the first cycle information and a PTW of the first terminal; and determine the second cycle information based on the first information. Processing module 702 is configured to determine, based on the second cycle information, a cycle in which a network pages the first terminal.

[00255] Alternatively, interface module 701 is configured to receive first information, the first information being determined based on the eDRX information of a first terminal, and the first information includes at least one parameter. Processing module 702 is configured to determine the second cycle information based on the first information and to determine, based on the second cycle information, a cycle in which a network pages the first terminal.

[00256] It should be understood that all content related to the steps of the method modalities above can be cited in the function descriptions of the corresponding functional modules. Details are not described in this document.

[00257] During specific implementation, the device may present a plurality of product forms. Several possible product forms are described below.

[00258] See FIG. 9. One embodiment of this application also provides a communication device 110. It can be understood Petition 870250099585, dated 10 / 30 / 2025, pp. 74 / 87 68 / 73 that the communication apparatus 110 includes technical means in the necessary forms, for example, modules, units, elements, circuits or interfaces, which are appropriately configured together to implement the solution. The communication apparatus 110 may be the terminal device 101, the terminal device 102 or the network device 103 in FIG. 1, or it may be a component (for example, a chip) in these devices, and is configured to implement the method performed by the first terminal, the second terminal or the network device in the previous method embodiments.

[00259] The communication device 110 includes one or more processors 111. The processor 111 may be a general-purpose processor, a dedicated processor, or similar. For example, the processor 111 may be a baseband processor or a central processing unit. The baseband processor may be configured to process a communication protocol and communication data. The central processing unit may be configured to: control the communication device (e.g., a RAN node, a terminal, or a chip), execute a software program, and process data from the software program.

[00260] Optionally, in a project, processor 111 may include a program 113 (which may sometimes also be called code or instructions). Program 113 may run on processor 111, so that communication device 110 performs the method performed by the first terminal, the second terminal, or the network device in the previous method modes.

[00261] In another possible design, the communication device 110 includes a circuit (not shown in FIG. 9). The circuit is configured to implement a function of the method performed by the first terminal, the second terminal, or the network device in the previous method modes.

[00262] Optionally, the communication device 110 may include one or more memories 112 that store a program 114 Petition 870250099585, dated 10 / 30 / 2025, pp. 75 / 87 69 / 73 (which may sometimes also be called code or instructions). Program 114 may run on processor 111, so that communication device 110 performs the method performed by the first terminal, the second terminal, or the network device in the previous method modes.

[00263] Optionally, processor 111 and / or memory 112 may include AI modules 117 and 118, and the AI ​​module is configured to implement an AI-related function. The AI ​​module may be implemented using software, hardware, or a combination of software and hardware. For example, the AI ​​module may include a RIC module. For example, the AI ​​module may be a near real-time RIC or a non-real-time RIC.

[00264] Optionally, processor 111 and / or memory 112 may store additional data. The processor and memory may be arranged separately or may be integrated together.

[00265] Optionally, the communication apparatus 110 may also include a transceiver 115 and / or an antenna 116.

The transceiver 115 may also sometimes be called the transceiver unit, transceiver machine, transceiver circuit, transceiver or similar, and is configured to implement a transceiver function of the communication apparatus via the antenna 116.

[00266] It should be understood that the processor mentioned in this application mode can be implemented by hardware or software. When the processor is implemented using hardware, the processor can be a logic circuit, an integrated circuit, or similar. When the processor is implemented using software, the processor can be a general-purpose processor, and is implemented by reading software code stored in memory.

[00267] For example, the processor can be a unit of Petition 870250099585, dated 10 / 30 / 2025, pp. 76 / 87 70 / 73 Central Processing Unit (CPU), or it may be another general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), or other programmable logic device, discrete gate logic device or transistor, discrete hardware component or similar. The general-purpose processor may be a microprocessor, or the processor may be any conventional processor or similar.

[00268] It should be understood that the memory mentioned in the embodiments of this application may be volatile memory or non-volatile memory, or may include both volatile and non-volatile memory. Non-volatile memory may be read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EPROM), or flash memory. Volatile memory may be random access memory (RAM), used as an external cache.By way of example and not limitation, RAMs can be used in many forms, for example, static random access memory (SRAM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), double data rate synchronous dynamic random access memory (DDR SDRAM), enhanced synchronous dynamic random access memory (ESDRAM), synchlink dynamic random access memory (SLDRAM), and direct Rambus random access memory (DR RAM).

[00269] It should be noted that when the processor is a Petition 870250099585, dated 10 / 30 / 2025, pp. 77 / 87 71 / 73 general-purpose processor, a DSP, an ASIC, an FPGA or other programmable logic device, a discrete gate or transistor logic device or a discrete hardware component, the memory (storage module) may be integrated into the processor.

[00270] It should be noted that the memory described in this descriptive report aims to include, but is not limited to, these memories and any other suitable type of memory.

[00271] Based on the same technical concept, one embodiment of this application also provides a computer-readable storage medium, including a program or instructions. When the program or instructions run on a computer, the method performed by the first terminal or the second terminal is performed.

[00272] Based on the same technical concept, an embodiment of this application further provides a computer program product including instructions. The computer program product stores the instructions and, when the computer program product runs on a computer, the method performed by the first terminal or the second terminal is performed.

[00273] Based on the same technical concept, one embodiment of this application further provides a chip. The chip may include a processor and also memory (or the chip is coupled to the memory). The chip executes program instructions in memory to perform the method performed by the first terminal, the second terminal, or the network device in the previous embodiments. Coupling means that two components are directly or indirectly combined with each other. For example, coupling may mean an electrical connection between the two components.
