Description

[Technical field]

[0001] The present application relates to the field of communication technology, and in particular to a terminal support information reporting method, an acquiring method and an apparatus thereof. [Background technology]

[0002] In order to support direct communication between terminal devices, a sidelink (also called SL) communication method is introduced, and the interface between the terminal devices is a PC-5 (sidelink communication) interface. According to the correspondence between the transmitting terminal device and the receiving terminal device, three transmission methods are supported in the sidelink: unicast, multicast, and broadcast. When a first terminal device in a connected state communicates on the sidelink, it needs to send a SidelinkUEInformation (sidelink communication terminal information) message containing a Sidelink transmission resource request information list to a network side device (e.g., a base station).

[0003] In the related art, when a first terminal device reports a sidelink transmission resource request information list to a network side device, the destination address field in the transmission resource request in the sidelink transmission resource request information list is used to indicate the identifier of the second terminal device connected by unicast. However, since the signaling of the sidelink transmission resource request information list cannot be expanded at present, it is not possible to add fields to the sidelink transmission resource request information list for indicating support information such as a paging identifier, sidelink discontinuous reception (SL DRX) support information, and SL DRX configuration. Adding the destination address (also called an identifier) ​​of the second terminal device to the support information such as the paging identifier, SL DRX support information, and SL DRX configuration reported by the first terminal device will increase a large amount of signaling overhead. Therefore, how to indicate support information such as the paging identifier, SL DRX support information, and SL DRX configuration to achieve the purpose of reducing signaling overhead is an issue that needs to be solved urgently.

The embodiments described below with reference to the accompanying drawings are illustrative and are for the purpose of explaining the present application, and should not be understood as limitations of the present application.

For example, A and / or B can indicate three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0083] The terms used in the embodiments of the present application are intended to describe particular embodiments and are not intended to limit the embodiments of the present application. Unless the context clearly indicates otherwise, the singular forms "a," "an," and "the" used in the embodiments of the present application and the appended claims also include the plural forms.

[0084] It should be understood that, although various information may be described in the embodiments of the present application with terms such as first, second, third, etc., these information should not be limited to these terms. These terms are used only to distinguish the same type of information from each other. For example, the first information may be called the second information, and similarly, the second information may be called the first information, without departing from the scope of the embodiments of the present application. Depending on the context, the term "when" used herein may be interpreted as "when" or "when" or "in response to determining."

[0085] The present application will be described in detail below with reference to the accompanying drawings, examples of which are shown in the drawings, in which the same or similar reference numerals throughout indicate the same or similar elements. The embodiments described below with reference to the accompanying drawings are illustrative and are for explaining the present application, and cannot be understood as limiting the present application.

[0086] In addition, in order to support direct communication between terminal devices, a sidelink (also called SL) communication method has been introduced, and the interface between the terminal devices is a PC-5 (sidelink communication) interface. Depending on the correspondence between the transmitting terminal device and the receiving terminal device, sidelink supports three transmission methods: unicast, multicast, and broadcast.

[0087] When a first terminal device in a connected state communicates in a sidelink, it needs to send a SidelinkUEInformation message containing a sidelink (SL) transmission resource request information list to a network side device (e.g., a base station). Here, as shown in Fig. 1, each element in the sidelink (SL) resource request information list is a sidelink (SL) resource request of a second terminal device, which includes a destination address of the second terminal device, a corresponding transmission method (including unicast, multicast and broadcast), a quality of service (QoS) and a target transmission frequency.

[0088] At present, one terminal device is not directly connected to a base station, but can realize communication with the base station by relaying the other terminal device. Here, the terminal device that is not connected to the base station is called a remote terminal device (remote UE), the terminal device that provides the relay function is called a relay terminal device (relay UE), and unicast communication is performed between the remote terminal device and the relay terminal device via sidelink.

[0089] It should be understood that the paging message sent by the network side device to the second terminal device (e.g., a remote terminal device) is sent to the first terminal device (e.g., an intermediate terminal device) by dedicated signaling, and then forwarded by the first terminal device to the second terminal device. The first terminal device needs to report the paging identifier of the second terminal device to the network side device, and the paging identifier may be NG-5G-S-TMSI or I-RNTI.

[0090] In order to save the device power consumption when a terminal device performs sidelink communication, sidelink discontinuous reception (DRX) is introduced. The receiving terminal device monitors the physical sidelink control channel (PSCCH) only during the activation time, thereby achieving the purpose of energy saving.

[0091] The unicast sidelink discontinuous reception (SL DRX) setting information is transmitted by the transmitting terminal device to the receiving terminal device, and the receiving terminal device can transmit SL DRX assistance information including the advised SL DRX setting information to the transmitting terminal device. When the receiving terminal device is in a connected state, it reports the received SL DRX setting information to the base station. The base station can save power by adjusting Uu (cellular network communication interface) DRX so that SL DRX and Uu DRX overlap as much as possible. When the transmitting terminal device is in a connected state, it reports the received SL DRX assistance information to the base station. The base station determines the SL DRX setting based on this SL DRX assistance information.

[0092] In the related art, as shown in FIG. 1, when a first terminal device reports a sidelink resource request information list to a network side device, the destination address field in the resource request in the sidelink resource request information list is used to indicate the identifier of the second terminal device connected by unicast. However, since the signaling of the sidelink resource request information list cannot be expanded at present, it is not possible to add fields to the sidelink resource request information list for indicating support information such as a paging identifier, sidelink discontinuous reception (SL DRX) support information, and SL DRX configuration. Adding the destination address (also called an identifier) ​​of the second terminal device to the support information such as the paging identifier, SL DRX support information, and SL DRX configuration reported by the first terminal device will increase a large amount of signaling overhead. Therefore, how to indicate support information such as the paging identifier, SL DRX support information, and SL DRX configuration to achieve the purpose of reducing signaling overhead is an issue that needs to be resolved urgently.

[0093] Based on the above problems, the present application proposes a terminal assistance information reporting method, an acquisition method and an apparatus thereof, which can realize the indication of the second terminal device to which the assistance information applies by using the existing destination address field in the sidelink (SL) resource request information list, and can save the signaling overhead of reporting the assistance information.

[0094] Figure 2 is a schematic diagram of the architecture of a communication system provided by an embodiment of the present application. The communication system may include, but is not limited to, one network device and two terminal devices, and the number and form of devices shown in Figure 2 are only exemplary and do not constitute limitations of the embodiment of the present application, and in actual applications, the system may include two or more network devices and two or more terminal devices. Take for example that the communication system shown in Figure 2 includes one network device 201 and two terminal devices 202. Here, the terminal device 202 is a sidelink terminal device.

[0095] It should be noted that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as a long term evolution (LTE) system, a 5th generation (5G) mobile communication system, a 5G new radio (NR) system, or other future new mobile communication systems. It should be noted that the side link in the embodiments of the present application may also be referred to as a direct connection link or a direct link.

[0096] The network device 201 in the embodiment of the present application is a network-side entity for transmitting and receiving signals. For example, the network device 201 may be an evolved base station (eNB), a transmission reception point (TRP), a next generation base station (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiment of the present application does not limit the specific technology and specific device form adopted by the network device. The network device provided by the embodiment of the present application may be composed of a central unit (CU) and a distributed unit (DU), where the CU is also called a control unit, and a CU-DU structure is adopted to separate the protocol layer of a network device, for example, a base station, to centrally control some protocol layer functions in the CU, and to distribute some or all of the remaining protocol layer functions to the DU, and the DU can be centrally controlled by the CU.

[0097] The terminal device 202 in the embodiment of the present application is a user-side entity for receiving or transmitting signals, such as a mobile phone.

Specifically, the network device 201 can transmit resource allocation information to the terminal device 202, and then allocate resources to other terminal devices through the terminal device 202 so that the other terminal devices can transmit information to the network device 201 through the allocated resources.

[0100] The terminal support information reporting method, the terminal support information obtaining method and the terminal support information obtaining device provided in the present application will be described in detail below in conjunction with the drawings.

[0101] Referring to Fig. 3, Fig. 3 is a schematic flow chart of a terminal support information reporting method provided by an embodiment of the present application. It should be noted that the terminal support information reporting method of the embodiment of the present application can be performed by a first terminal device. As shown in Fig. 3, the terminal support information reporting method can include, but is not limited to, the following steps:

[0102] In step 301, send a side link (SL) resource request information list and an assistance information list to a network side device, where the resource request information list includes a resource request of a second terminal device, the resource request of the second terminal device includes a destination address of the second terminal device, the assistance information list includes assistance information, and the assistance information determines a terminal device identifier corresponding to the assistance information through an index identifier, where the terminal device identifier corresponding to the assistance information is a destination address in the resource request located at an index identifier position in the resource request information list.

[0103] In some embodiments of the present application, the assistance information in this reported assistance information list may be a paging identifier, or may be sidelink discontinuous reception (SL DRX) assistance information, or may be a SL DRX configuration, etc.

[0104] In one implementation, the length of the assistance information list may be 1. That is, the first terminal device may report an assistance information list to the network side device, and the assistance information list may include one or more pieces of assistance information, where each assistance information in the assistance information list may determine a UE identifier to which the assistance information applies through an index identifier, and the UE identifier may be a destination address in a resource request located at an index identifier position in the resource request information list.

[0105] In addition, when the first terminal device in a connected state communicates in a sidelink, it is necessary to transmit a SidelinkUEInformation message including a sidelink (SL) transmission resource request information list to a network side device (e.g., a base station). Each element in the resource request information list is a resource request of the second terminal device, and the resource request includes the destination address of the second terminal device, the corresponding transmission method (including unicast, multicast and broadcast), the quality of service QoS and the target transmission frequency. In the embodiment of the present application, when the first terminal device reports the assistance information to the network side device, a mapping relationship between the assistance information and the destination address of the second terminal device in the resource request information list is established by an index identifier corresponding to the assistance information, so that the network side device identifies the second terminal to which the assistance information transmitted from the first terminal device is applied based on this mapping relationship, thereby realizing the indication of the second terminal device to which the assistance information is applied by the existing destination address field in the resource request information list.

[0106] It should be noted that in some embodiments of the present application, there are various ways to set this index identifier, for example, it may be included in the corresponding assistance information, or the index identifier corresponding to the assistance information may be set according to the index position in the resource request information list of the resource request. Below, examples are given to respectively describe different ways to set the index identifier and establish a mapping relationship between the assistance information and the destination address of the second terminal device in the resource request information list by the index identifier.

[0107] As an example of one possible implementation, assume that the resource request information list (eg, SL-TxResourceReqList-r16) reported from the first terminal device has four elements, as shown in Table 1 below.

[0108] [Table 1]

[0109] Assuming that the assistance information that the first terminal device needs to report is SL DRX setting information, the reported SL DRX setting information may be, for example, that for a second terminal device whose destination address (also referred to as identifier) ​​is 00000001, its SL DRX setting information is A, and for a second terminal device whose destination address (also referred to as identifier) ​​is 00000011, its SL DRX setting information is B. Because the setting methods of the index identifiers are different, the formats of the assistance information lists reported by the first terminal device to the network side device are also different.

[0110] In one implementation, the index identifier is included in the corresponding assistance information. In such a case, the index identifier can be set based on the index position in the resource request information list of the transmission resource request corresponding to the destination address of the first terminal device and the second terminal device. In such an implementation, the assistance information list reported by the first terminal device to the network side device can be, for example, as shown in Table 2.

[0111] [Table 2]

[0112] Here, from Tables 1 and 2, the SL-DestinationIdentity-r16 of a UE whose SL DRX setting in the reported support information list is A is the SL-DestinationIdentity-r16 of the second (index identifier) ​​entry in the resource request information list (e.g., SL-TxResourceReqList-r16), i.e., 00000001. In this way, the SL-DestinationIdentity-r16 of a UE whose SL DRX setting in the reported support information list is B is the SL-DestinationIdentity-r16 of the fourth (index identifier) ​​entry in the resource request information list (e.g., SL-TxResourceReqList-r16), i.e., 00000011.

[0113] In another implementation, the index identifier in the embodiment of the present application is determined by the position of the assistance information in the assistance information list. In such a case, the first terminal device needs to set the assistance information to the same index position in the assistance information list according to the index position in the resource request information list of the resource request corresponding to the destination address of the second terminal device, where the assistance information list has the same length as the resource request information list. If a target UE does not have assistance information, it should be emptied but the entry should be kept. In such an implementation, the assistance information list reported by the first terminal device to the network side device can be, for example, as shown in Table 3 below.

[0114] [Table 3]

[0115] Here, if the SL DRX configuration in Table 3 is A, first determine that the index identifier of A is the second, which is its index position in the support information list, and then obtain the UE identifier of A by the index identifier, i.e., the SL-DestinationIdentity-r16 of the UE whose SL DRX configuration in the reported support information list is A is the SL-DestinationIdentity-r16 of the second (index identifier) ​​entry in the resource request information list (e.g., SL-TxResourceReqList-r16), i.e., 00000001.

[0116] In this way, if the SL DRX configuration in Table 3 is B, first determine that the index identifier of B is the 4th, which is its index position in the support information list, and then obtain the UE identifier of B by the index identifier, i.e., the SL-DestinationIdentity-r16 of the UE whose SL DRX configuration in the reported support information list is B is the SL-DestinationIdentity-r16 of the 4th (index identifier) ​​entry in the resource request information list (e.g., SL-TxResourceReqList-r16), i.e., 00000011.

[0117] In some embodiments of the present application, the assistance information in the reported assistance information list may be a paging identifier, or may be sidelink discontinuous reception (SL DRX) assistance information, or may be a SL DRX configuration, etc. In one implementation, the assistance information may include a paging identifier of a second terminal device, where the second terminal device is a remote terminal device.

[0118] That is, when the first terminal device is a relay UE, the assistance information in the reported assistance information list may include a paging identifier of the second terminal device. For example, when the first terminal device is a relay UE, the relay UE needs to report the paging identifier of the second terminal device (e.g., a remote UE) to the network side device, so that the network side device sends a paging message sent to the second terminal device to the relay UE, and forwards the paging message to the second terminal device by the relay UE.

[0119] In one implementation, the assistance information may include a sidelink discontinuous reception (SL DRX) configuration, where the sidelink discontinuous reception (SL DRX) configuration is a SL DRX configuration received by the first terminal device and transmitted from the second terminal device, and the first terminal device accepts the SL DRX configuration.

[0120] That is, when a first terminal device receives a SL DRX configuration transmitted from a second terminal device, and the first terminal device accepts this SL DRX configuration, the support information in the support information list reported by the first terminal device may include this SL DRX configuration.

[0121] In one implementation, the assistance information may include received SL DRX assistance information, where the SL DRX assistance information is SL DRX assistance information received by the first terminal device and transmitted from the second terminal device.

[0122] That is, when a first terminal device receives SL DRX assistance information transmitted from a second terminal device, the assistance information in the assistance information list reported by the first terminal device may include the received SL DRX assistance information.

[0123] By implementing the embodiment of the present application, when reporting the terminal assistance information, the index identifier can determine the identifier of the terminal device UE to which the terminal assistance information is applied, and the identifier of the terminal device UE is the destination address in the transmission resource request located at the index identifier position in the resource request information list. Thus, the embodiment of the present application uses the index identifier to establish a mapping relationship between the assistance information and the destination address of the opposite terminal device UE in the resource request information list, thereby realizing the instruction to the opposite terminal device when reporting the terminal assistance information, and saving the signaling overhead of reporting the terminal assistance information.

[0124] Referring to Fig. 4, Fig. 4 is a schematic flow chart of a terminal support information reporting method provided by an embodiment of the present application. It should be noted that the terminal support information reporting method of the embodiment of the present application can be performed by a first terminal device. As shown in Fig. 4, the terminal support information reporting method can include, but is not limited to, the following steps:

[0125] In step 401, send a sidelink (SL) resource request information list and an assistance information list to a network side device, where the resource request information list includes multiple resource requests, each resource request corresponds to an index position, and the assistance information list includes assistance information of a second terminal device and an index identifier corresponding to the assistance information, where the index identifier corresponds to the index position corresponding to the resource request.

[0126] In some embodiments of the present application, the assistance information in this assistance information list may be a paging identifier, or may be sidelink discontinuous reception (SL DRX) assistance information, or may be a SL DRX configuration, etc.

[0127] In one implementation, the length of the assistance information list may be 1. That is, in addition to sending the sidelink (SL) resource request information list to the network side device, the first terminal device may also send the assistance information list to the network side device, where the assistance information list may include assistance information of one or more second terminal devices and an index identifier corresponding to the assistance information, and the index identifier corresponds to the index position in the resource request information list of the resource request. Since the resource request has the destination address of the second terminal device, after receiving the resource request information list and the assistance information list reported by the first terminal device, the network side device can realize the indication of the second terminal device to which each assistance information in the assistance information list applies by the existing destination address field in the resource request information list, and can save the signaling overhead of reporting the assistance information.

[0128] In addition, when the first terminal device in a connected state communicates in a sidelink, it is necessary to transmit a SidelinkUEInformation (sidelink communication terminal information) message including a sidelink (SL) transmission resource request information list to a network side device (e.g., a base station). Each element in the resource request information list is a resource request of the second terminal device, and the resource request includes the destination address of the second terminal device, the corresponding transmission method (including unicast, multicast and broadcast), the quality of service QoS and the target transmission frequency. In the embodiment of the present application, when the first terminal device reports the assistance information to the network side device, a mapping relationship between the assistance information and the destination address of the second terminal device in the resource request information list is established by an index identifier corresponding to the assistance information, so that the network side device identifies the second terminal to which the assistance information transmitted from the first terminal device is applied based on this mapping relationship, thereby realizing the indication of the second terminal device to which the assistance information is applied by the existing destination address field in the resource request information list.

[0129] It should be noted that in some embodiments of the present application, there are various ways to set this index identifier, for example, it may be included in the corresponding assistance information, or the index identifier corresponding to the assistance information may be set according to the index position in the resource request information list of the resource request. Below, examples are given to respectively describe different ways to set the index identifier and establish a mapping relationship between the assistance information and the destination address of the second terminal device in the resource request information list by the index identifier.

[0130] As an example of a possible implementation, assuming that the resource request information list (e.g., SL-TxResourceReqList-r16) reported by the first terminal device has four elements, for example, as shown in the above Table 1. Assuming that the assistance information that the first terminal device needs to report is SL DRX configuration information, the reported SL DRX configuration information may be, for example, that for a second terminal device whose destination address (also called identifier) ​​is 00000001, its SL DRX configuration information is A, and for a second terminal device whose destination address (also called identifier) ​​is 00000011, its SL DRX configuration information is B. Since the setting methods of the index identifiers are different, the manner in which the first terminal device reports the assistance information list to the network side device is also different.

[0131] In one implementation, the index identifier is included in the corresponding assistance information. In such a case, the first terminal device can determine an index position in the resource request information list of the resource request, and set an index identifier corresponding to the assistance information in the assistance information list based on the index position. After setting an index identifier corresponding to the assistance information in the assistance information list based on the index position, the first terminal device can send the set assistance information list and the resource request information list to the network side device.

[0132] For example, the format of the assistance information list reported by the first terminal device to the network side device can be, for example, as shown in Table 2 above. Here, from Tables 1 and 2, the destination address of the second terminal device to which the SL DRX setting information A in the reported assistance information list is applied is the destination address whose index position in the resource request information list (for example, SL-TxResourceReqList-r16) is 2, i.e., 00000001. Thus, the destination address of the second terminal device to which the SL DRX setting B in the reported assistance information list is applied is the destination address whose index position in the resource request information list (for example, SL-TxResourceReqList-r16) is 4, i.e., 00000011. After receiving the resource request information list and the assistance information list transmitted by the first terminal device, the network side device can determine the resource request located at the index position in the resource request information list based on the index identifier corresponding to the assistance information in the assistance information list, and obtain the destination address in the resource request located at the index position, where the terminal device having the destination address is the second terminal device to which the assistance information is applied.

[0133] For example, assuming that the resource request information list transmitted from the first terminal device is, for example, as shown in Table 1 above, and the transmitted assistance information list is, for example, as shown in Table 2 above, the network side device can determine a resource request having an index position of 2 in the resource request information list based on the index identifier "2" corresponding to the assistance information, thereby knowing that the terminal device to which this assistance information (i.e., the SL DRX setting information is A in Table 2 above) is applied is the second terminal device having destination address "00000001". In this way, the network side device can determine a resource request having an index position of 4 in the resource request information list based on the index identifier "4" corresponding to the assistance information, thereby knowing that the terminal device to which this assistance information (i.e., the SL DRX setting information is B in Table 2 above) is applied is the second terminal device having destination address "00000011".

[0134] In another implementation, the support information list has the same length as the resource request information list, and the index position of the resource request in the resource request information list is the same as the index position of the support information in the support information list. Here, the index identifier corresponding to the support information may be the index position of the support information in the support information list. That is, the first terminal device needs to set the support information of the second terminal device to the same index position in the support information list based on the index position of the resource request of the second terminal device in the resource request information list. If a second terminal device does not have support information, the corresponding position in the support information list is emptied.

[0135] For example, the format of the support information list reported by the first terminal device to the network side device may be, for example, as shown in Table 3 below.

[0136] [Table 4]

[0137] That is, assume that the length of the support information list of the first terminal device set is the same as the length of the resource request information list, both of which are 4, and the terminal device to which the SL DRX setting information A is applied is the second terminal device with a destination address of 00000001, and the terminal device to which the SL DRX setting information B is applied is the second terminal device with a destination address of 00000011. The first terminal device needs to set the SL DRX setting information A at a position with an index position of 2 in the support information list based on the index position (for example, 2) in the resource request information list of the resource request of the second terminal device. In this way, the first terminal device needs to set the SL DRX setting information B at a position with an index position of 4 in the support information list based on the index position (for example, 4) in the resource request information list of the resource request of the second terminal device. If another second terminal device does not have support information in the resource request information list, the corresponding position in the support information list is left empty, that is, the format of the support information list of this first terminal device set can be, for example, as shown in Table 3 above. The first terminal device sets the support information to the same index position in the support information list based on the index position in the resource request information list of the resource request, and then transmits the set support information list and the resource request information list to the network side device.

[0138] In this example, after receiving the resource request information list and the assistance information list sent from the first terminal device, the network side device can determine the resource request located at the index position in the resource request information list based on the index identifier corresponding to the assistance information in the assistance information list, and obtain the destination address in the resource request located at the index position, where the terminal device having the destination address is the second terminal device to which the assistance information applies. For example, assuming that the resource request information list sent from the first terminal device is, for example, as shown in the above Table 1, and the transmitted assistance information list is, for example, as shown in the above Table 3, the network side device can determine the resource request whose index position is 2 in the resource request information list based on the index identifier "2" corresponding to the assistance information (i.e., the position of the assistance information in the assistance information list), thereby knowing that the terminal device to which this assistance information (i.e., the SL DRX setting information is A in the above Table 3) applies is the second terminal device with the destination address "00000001". In this way, the network side device can determine the resource request whose index position is 4 in the resource request information list based on the index identifier “4” corresponding to the assistance information, and thereby know that the terminal device to which this assistance information (i.e., the SL DRX setting information is B in Table 3 above) applies is the second terminal device having the destination address “00000011”.

[0139] By implementing the embodiments of the present application, a mapping relationship is established between the assistance information and the destination address of the second terminal device in the resource request information list by an index identifier corresponding to the assistance information, so that the network side device identifies the second terminal to which the assistance information sent from the first terminal device applies based on this mapping relationship, thereby realizing the indication of the second terminal device to which the assistance information applies through the existing destination address field in the resource request information list, and saving the signaling overhead of reporting the assistance information.

[0140] In some embodiments of the present application, the assistance information in the reported assistance information list may be a paging identifier, or may be SL DRX assistance information, or may be SL DRX setting information, etc. In addition, when the content of the assistance information reported by the first terminal device to the network side device is different, the roles played by the first terminal device and the second terminal device are also different. For example, when the assistance information transmitted by the first terminal device to the network side device is a paging identifier, the first terminal device is a relay terminal device, and the second terminal device is a remote terminal device. Also, for example, when the assistance information transmitted by the first terminal device to the network side device is SL DRX assistance information, the first terminal device is a transmitting terminal device, and the second terminal device is a receiving terminal device. Also, for example, when the assistance information transmitted by the first terminal device to the network side device is SL DRX setting information, the first terminal device is a receiving terminal device, and the second terminal device is a transmitting terminal device. Each of these will be described in detail below based on the embodiments.

[0141] Referring to FIG. 5, FIG. 5 is a schematic flowchart of another terminal assistance information reporting method provided by an embodiment of the present application. Wherein, the terminal assistance information reporting method of the embodiment of the present application can be performed by a first terminal device. Wherein, the assistance information is a paging identifier. As shown in FIG. 5, this terminal assistance information reporting method can include, but is not limited to, the following steps:

[0142] In step 501, a paging identifier transmitted from a second terminal device is received.

[0143] Optionally, in the embodiment of the present application, the first terminal device is an intermediate terminal device, and the second terminal device is a remote terminal device. When the second terminal device sends a paging request to the network side device, the second terminal device sends its own paging identifier to the first terminal device. The first terminal device can receive the paging identifier sent from the second terminal device and send the paging identifier to the network side device, so that the network side device sends a paging message of the paging identifier to the second terminal device via the first terminal device.

[0144] In step 502, a paging identifier is determined as the aiding information of the second terminal device.

[0145] Optionally, when the first terminal device receives a paging identifier sent from a second terminal device, the first terminal device can determine the paging identifier as the assistance information of the second terminal device. Since the first terminal device needs to report a resource request information list to the network side device to realize the network side device's setting of the sidelink resources of the second terminal device in the list, the first terminal device can use the destination address of the second terminal device in the resource request information list to indicate which second terminal device is specifically the terminal device to which the paging identifier applies.

[0146] In one implementation form, after the first terminal device determines a paging identifier as the assistance information of the second terminal device, it can determine an index position in a resource request information list of a sidelink resource request of the second terminal device, and set an index identifier corresponding to the paging identifier in the assistance information list based on the index position, thereby setting the paging identifier and its corresponding index identifier in the assistance information list.

[0147] For example, suppose that the resource request information list (e.g., SL-TxResourceReqList-r16) that the first terminal device needs to report has four elements, for example, as shown in Table 1 above. Assume that the assistance information received by the first terminal device is a paging identifier C sent from a second terminal device with a destination address "00000001" and a paging identifier D sent from a second terminal device with a destination address "00000011". The first terminal device determines that the index position in the resource request information list of the resource request of the second terminal device with destination address "00000001" is 2, and based on this index position, can set an index identifier corresponding to this paging identifier C in the assistance information list, i.e., this index identifier is 2, and the form of this paging identifier C and the index identifier in the assistance information list can be, for example, as shown in Table 4 below. The first terminal device determines that the index position in the resource request information list of the resource request of the second terminal device having the destination address "00000011" is 4, and can set an index identifier corresponding to this paging identifier D in the support information list based on this index position, i.e., this index identifier is 4, and the form of this paging identifier D and the index identifier in the support information list can be, for example, as shown in the following Table 4. The first terminal device sets this paging identifier C and its corresponding index identifier, paging identifier D and its corresponding index identifier in the support information list, and the form of this support information list can be, for example, as shown in Table 4.

[0148] [Table 5]

[0149] In another implementation form, after the first terminal device determines the paging identifier as the assistance information of the second terminal device, it can set the assistance information corresponding to the same index position in the assistance information list based on the index position in the resource request information list of the resource request, where the index identifier corresponding to the assistance information corresponds to the index position in the assistance information list of the assistance information, and the assistance information list has the same length as the resource request information list.

[0150] For example, suppose that the sidelink (SL) resource request information list (e.g., SL-TxResourceReqList-r16) that the first terminal device needs to report has four elements, for example, as shown in Table 1 above. Assume that the assistance information received by the first terminal device is a paging identifier C sent from a second terminal device having a destination address "00000001" and a paging identifier D sent from a second terminal device having a destination address "00000011". The first terminal device can determine that the index position in the resource request information list of the resource request of the second terminal device having the destination address "00000001" is 2, and set this paging identifier C to the same index position in the assistance information list based on this index position, for example, set this paging identifier C to the position in the assistance information list where the index position is 2, as shown in Table 5 below. The first terminal device determines that the index position in the resource request information list of the resource request of the second terminal device having the destination address "00000011" is 4, and based on this index position, can set this paging identifier D to the same index position in the support information list, for example, set this paging identifier D to the position in the support information list whose index position is 4, as shown in Table 5 below.

[0151] [Table 6]

[0152] In step 503, a side link (SL) resource request information list and an assistance information list are sent to a network side device.

[0153] Here, in an embodiment of the present application, the resource request information list includes multiple resource requests, where one resource request corresponds to one index position, and the support information list includes support information of the second terminal device and an index identifier corresponding to the support information, where the index identifier corresponds to the index position corresponding to the resource request.

[0154] That is, after receiving a paging identifier transmitted from a second terminal device, the first terminal device determines the paging identifier as the assistance information of the second terminal device, and establishes a mapping relationship between the assistance information and the destination address of the second terminal device in the resource request information list by an index identifier corresponding to the assistance information, so that the network side device identifies the second terminal to which the assistance information transmitted from the first terminal device applies based on this mapping relationship, thereby realizing the indication of the second terminal device to which the assistance information applies by the existing destination address field in the resource request information list, and saving the signaling overhead of reporting the assistance information.

[0155] Referring to Fig. 6, Fig. 6 is a schematic flow chart of a further terminal support information reporting method provided by an embodiment of the present application. It should be noted that the terminal support information reporting method of the embodiment of the present application can be performed by a first terminal device. Wherein, the support information is SL DRX configuration information. As shown in Fig. 6, the terminal support information reporting method can include, but is not limited to, the following steps:

[0156] In step 601, receive SL DRX setting information sent from a second terminal device.

[0157] Optionally, in the embodiment of the present application, the first terminal device is a receiving terminal device, and the second terminal device is a transmitting terminal device. In order to save power, the network side device (e.g., a base station) can adjust the Uu DRX based on the SL DRX setting information of the sidelink terminal device so that the SL DRX and the Uu DRX overlap as much as possible. In this case, the first terminal device receives the SL DRX setting information transmitted from the second terminal device, and the second terminal device decides whether to accept the SL DRX setting information. If the first terminal device decides to accept the SL DRX setting information, the first terminal device needs to report the SL DRX setting information to the network side device, so that the network side device adjusts the Uu DRX so that the SL DRX and the Uu DRX overlap as much as possible, thereby saving power.

[0158] In step 602, the SL DRX configuration information is determined as the assistance information of the second terminal device.

[0159] Optionally, when the first terminal device receives the SL DRX setting information transmitted from the second terminal device, the first terminal device can determine the SL DRX setting information as the assistance information of the second terminal device. Since the first terminal device needs to report a resource request information list to the network side device to realize the network side device's setting of the sidelink resources of the second terminal device in the list, the first terminal device can use the destination address of the second terminal device in the resource request information list to indicate the terminal device of the SL DRX setting information.

[0160] Here, the implementation manner of the set of the assistance information list when the assistance information is SL DRX configuration information is similar to the implementation manner of the set of the assistance information list when the assistance information is a paging identifier. In one implementation form, after the first terminal device determines the SL DRX configuration information as the assistance information of the second terminal device, it determines an index position in the resource request information list of the sidelink resource request of the second terminal device, and sets an index identifier corresponding to the SL DRX configuration information in the assistance information list based on the index position, so that the SL DRX configuration information and the corresponding index identifier can be set in the assistance information list.

[0161] In another implementation form, after the first terminal device determines the SL DRX setting information as the assistance information of the second terminal device, it can set the assistance information to the same index position in the assistance information list based on the index position in the resource request information list of the resource request, where the index identifier corresponding to the assistance information is the index position in the assistance information list of the assistance information, and the assistance information list has the same length as the resource request information list.

[0162] In step 603, a side link (SL) resource request information list and an assistance information list are sent to a network side device.

[0163] Here, in an embodiment of the present application, the resource request information list includes multiple resource requests, where one resource request corresponds to one index position, and the support information list includes support information of the second terminal device and an index identifier corresponding to the support information, where the index identifier corresponds to the index position corresponding to the resource request.

[0164] That is, after receiving the SL DRX setting information transmitted from the second terminal device, the first terminal device, when in a connected state, determines the SL DRX setting information as the assistance information of the second terminal device, and establishes a mapping relationship between the assistance information and the destination address of the second terminal device in the resource request information list by an index identifier corresponding to the assistance information, so that the network side device identifies the second terminal to which the assistance information transmitted from the first terminal device applies based on this mapping relationship, thereby realizing the indication of the second terminal device to which the assistance information applies by the existing destination address field in the resource request information list, and saving the signaling overhead of reporting the assistance information.

[0165] Referring to Fig. 7, Fig. 7 is a schematic flow chart of a further terminal support information reporting method provided by an embodiment of the present application. It should be noted that the terminal support information reporting method of the embodiment of the present application can be performed by a first terminal device. Wherein, the support information is SL DRX support information. As shown in Fig. 7, the terminal support information reporting method can include, but is not limited to, the following steps:

[0166] In step 701, receive SL DRX assistance information sent from a second terminal device, where the SL DRX assistance information includes advised SL DRX configuration information.

[0167] Optionally, in an embodiment of the present application, the first terminal device is a transmitting terminal device, and the second terminal device is a receiving terminal device. In order to save power, the network side device (e.g., a base station) can adjust the Uu DRX based on the SL DRX configuration information of the sidelink terminal device so that the SL DRX and the Uu DRX overlap as much as possible. Here, the SL DRX configuration information may be the SL DRX configuration information advised in the SL DRX assistance information sent from the receiving terminal device.

[0168] For example, a unicast SL DRX is sent by a transmitting terminal device (e.g., a first terminal device in an embodiment of the present application) to a receiving terminal device (e.g., a second terminal device in an embodiment of the present application), so that the receiving terminal device can send SL DRX assistance information to the transmitting terminal device, and the SL DRX assistance information includes advised SL DRX setting information, so that when the transmitting terminal device is in a connected state, it reports the received SL DRX assistance information to a network side device (e.g., a base station), so that the network side device (e.g., a base station) determines the SL DRX setting based on the SL DRX assistance information.

[0169] In step 702, the SL DRX assistance information is determined as the assistance information of the second terminal device.

[0170] Optionally, when the first terminal device receives the SL DRX assistance information sent from the second terminal device, the first terminal device can determine the SL DRX assistance information as the assistance information of the second terminal device. Since the first terminal device needs to report a resource request information list to the network side device to realize the network side device's setting of the sidelink resources of the second terminal device in the list, the first terminal device can use the destination address of the second terminal device in the resource request information list to indicate the terminal device of the SL DRX assistance information.

[0171] Here, the implementation manner of setting the assistance information list when the assistance information is SL DRX assistance information is similar to the implementation manner of setting the assistance information list when the assistance information is a paging identifier. In one implementation form, after the first terminal device takes the SL DRX assistance information as the assistance information of the second terminal device, it determines an index position in the resource request information list of the sidelink resource request of the second terminal device, and sets an index identifier corresponding to this SL DRX assistance information in the assistance information list based on this index position, so that the SL DRX assistance information and its corresponding index identifier can be set in the assistance information list.

[0172] In another implementation form, after the first terminal device takes the SL DRX support information as the support information of the second terminal device, it can set the support information corresponding to the same index position in the support information list based on an index position in the resource request information list of the resource request, where an index identifier corresponding to the support information corresponds to an index position in the support information list of the support information, and the support information list has the same length as the resource request information list.

[0173] In step 703, a side link (SL) resource request information list and an assistance information list are sent to a network side device.

[0174] Here, in an embodiment of the present application, the resource request information list includes multiple resource requests, where one resource request corresponds to one index position, and the support information list includes support information of the second terminal device and an index identifier corresponding to the support information, where the index identifier corresponds to the index position corresponding to the resource request.

[0175] That is, after receiving the SL DRX assistance information transmitted from the second terminal device, the first terminal device, when in a connected state, determines the SL DRX assistance information as the assistance information of the second terminal device, and establishes a mapping relationship between the assistance information and the destination address of the second terminal device in the resource request information list by an index identifier corresponding to the assistance information, so that the network side device identifies the second terminal to which the assistance information transmitted from the first terminal device applies based on this mapping relationship, thereby realizing the indication of the second terminal device to which the assistance information applies by the existing destination address field in the resource request information list, and saving the signaling overhead of reporting the assistance information.

[0176] It should be noted that the above embodiment describes the implementation of the terminal support information reporting method of the embodiment of the present application at the first terminal device side. The embodiment of the present application further proposes a terminal support information acquisition method, and the implementation of the terminal support information acquisition method at the network side device side will be described below. Referring to FIG. 8, FIG. 8 is a schematic flowchart of the terminal support information acquisition method provided by the embodiment of the present application. It should be noted that the terminal support information acquisition method of the embodiment of the present application can be performed by the network side device. As shown in FIG. 8, the terminal support information acquisition method can include, but is not limited to, the following steps:

[0177] In step 801, a sidelink (SL) resource request information list and an assistance information list sent from a first terminal device are received, where the resource request information list includes a resource request of a second terminal device, the resource request of the second terminal device includes a destination address of the second terminal device, and the assistance information list includes assistance information, and the assistance information determines a terminal device identifier corresponding to the assistance information through an index identifier, where the terminal device identifier corresponding to the assistance information is a destination address in the resource request located at an index identifier position in the resource request information list.

[0178] In some embodiments of the present application, the assistance information in this reported assistance information list may be a paging identifier, or may be sidelink discontinuous reception (SL DRX) assistance information, or may be a SL DRX configuration, etc.

[0179] In one implementation, the length of the assistance information list may be 1. That is, the first terminal device can report the assistance information list to the network side device. The network side device can receive the assistance information list sent from the first terminal device, where the assistance information list can include one or more pieces of assistance information, where each piece of assistance information in the assistance information list can determine a UE identifier to which the assistance information applies by an index identifier, and the UE identifier can be a destination address in a resource request located at an index identifier position in the resource request information list.

[0180] In addition, when the first terminal device in a connected state communicates in a sidelink, it is necessary to transmit a SidelinkUEInformation message including a sidelink (SL) transmission resource request information list to a network side device (e.g., a base station). Each element in the resource request information list is a resource request of the second terminal device, and the resource request includes the destination address of the second terminal device, the corresponding transmission method (including unicast, multicast and broadcast), the quality of service QoS and the target transmission frequency. In the embodiment of the present application, when the first terminal device reports the assistance information to the network side device, a mapping relationship between the assistance information and the destination address of the second terminal device in the resource request information list is established by an index identifier corresponding to the assistance information, so that the network side device identifies the second terminal to which the assistance information transmitted from the first terminal device is applied based on this mapping relationship, thereby realizing the indication of the second terminal device to which the assistance information is applied by the existing destination address field in the resource request information list.

[0181] In some embodiments of the present application, the index identifier may be set in various ways, for example, it may be included in each piece of support information, or it may be determined by the position of the support information in the support information list. Here, the method of setting the index identifier may refer to the description of the implementation form of each embodiment above, and the description will be omitted here.

[0182] In some embodiments of the present application, the assistance information in the reported assistance information list may be a paging identifier, or may be sidelink discontinuous reception (SL DRX) assistance information, or may be a SL DRX configuration, etc. In one implementation, if the assistance information in the reported assistance information list is a paging identifier, the network side device may send paging information whose destination address is the paging identifier to the terminal device that reported the assistance information list.

[0183] That is, when the first terminal device is a relay UE, the assistance information in the reported assistance information list may include a paging identifier of the second terminal device. For example, when the first terminal device is a relay UE, the relay UE needs to report the paging identifier of the second terminal device (e.g., a remote UE) to the network side device, so that the network side device sends a paging message sent to the remote UE to the relay UE, and forwards the paging message to the remote UE by the relay UE.

[0184] In one implementation, if the assistance information in the reported assistance information list is a sidelink discontinuous reception (SL DRX) configuration, the network side device may schedule sidelink transmission resources to the second terminal device corresponding to the destination address within the activation time of the second terminal device corresponding to the destination address.

[0185] For example, as shown in Table 2 above, assuming that the network side device receives the assistance information “SL DRX configuration A” and determines that the SL DRX configuration A applies to the terminal device whose SL-DestinationIdentity-r16 of the second (index identifier) ​​entry in the resource request information list (e.g., SL-TxResourceReqList-r16) is 00000001, the network side device can schedule sidelink transmission resources to the terminal device whose destination address is 00000001 within the activation time of the terminal device whose destination address is 00000001.

[0186] In one implementation form, if the support information in this reported support information list is SL DRX support information, the network side device can determine the SL DRX configuration of the second terminal device corresponding to the destination address based on the SL DRX support information.

[0187] As an example, the SL DRX assistance information may include an advised SL DRX configuration. For example, assume that the assistance information in the assistance information list reported by the first terminal device received by the network side device is SL DRX assistance information, the advised SL DRX configuration included in the SL DRX assistance information is A, and the index identifier corresponding to the assistance information is 2. If the network side device determines based on the index identifier that the destination address in the resource request located at the second (index identifier) ​​position in the resource request information list is "00000001", the network side device can determine that the SL DRX assistance information applies to the terminal device whose destination address is "00000001", and the network side device can determine based on the SL DRX assistance information that the SL DRX configuration of the terminal device whose destination address is "00000001" is A.

[0188] By implementing the embodiment of the present application, when reporting the terminal assistance information, an index identifier can be used to determine the identifier of the terminal device UE to which the terminal assistance information is applied, and the identifier of the terminal device UE is the destination address in the resource request located at the index identifier position in the resource request information list. Thus, the embodiment of the present application uses the index identifier to establish a mapping relationship between the assistance information and the destination address of the opposite terminal device UE in the resource request information list, thereby realizing an instruction to the opposite terminal device when reporting the terminal assistance information, and saving the signaling overhead of reporting the terminal assistance information.

[0189] Referring to Fig. 9, Fig. 9 is a schematic flow chart of a terminal support information acquisition method provided by an embodiment of the present application. It should be noted that the terminal support information acquisition method of the embodiment of the present application can be performed by a network side device. As shown in Fig. 9, the terminal support information acquisition method can include, but is not limited to, the following steps:

[0190] In step 901, a sidelink (SL) resource request information list and an assistance information list sent from a first terminal device are received, where the resource request information list includes multiple resource requests, where one resource request corresponds to one index position, and the assistance information list includes assistance information of a second terminal device and an index identifier corresponding to the assistance information, where the index identifier corresponds to the index position corresponding to the resource request.

[0191] In the embodiments of the present application, the implementation form in which the first terminal device transmits the resource request information list and the support information list can be realized by any of the implementation forms in each embodiment of the present application, and the embodiments of the present application are not limited thereto, and no description will be given.

[0192] In step 902, a resource requirement is determined based on the index identifier.

[0193] Optionally, after receiving the resource request information list and the support information list sent from the first terminal device, the network side device can determine a resource request located at an index position in the resource request information list based on an index identifier corresponding to the support information in the support information list.

[0194] In step 903, a destination address in the resource request is obtained, where the terminal device having the destination address is a second terminal device.

[0195] Optionally, after determining the resource requirement, the network side device can obtain a destination address from the resource requirement, and the terminal device having the destination address is the second terminal device to which the assistance information applies.

[0196] Since the setting methods of the index identifier are different, the formats of the support information list are also different. For example, as shown in the above Tables 2 and 4, the index identifier may be included in the corresponding support information. For example, as shown in the above Tables 1, 3 and 5, the support information list has the same length as the resource request information list, and the index identifier corresponding to the support information can be understood as the index position of the support information in the support information list. That is, the network side device can determine the index identifier corresponding to the support information based on the position of the support information in the support information list, and can also determine the resource request located at the index position in the resource request information list based on the index identifier.

[0197] In one implementation, the index identifier is included in the corresponding assistance information. For example, assuming that the resource request information list (e.g., SL-TxResourceReqList-r16) reported by the first terminal device has four elements, for example, as shown in Table 1 above, and the reported assistance information list is for example, as shown in Table 2 above. After the network side device receives the resource request information list and the assistance information list reported by the first terminal device, the network side device determines the resource request whose index position is 2 in the resource request information list based on the index identifier "2" corresponding to the assistance information, and obtains the destination address 00000001 in the resource request whose index position is 2, thereby knowing that the terminal device to which this assistance information (i.e., the SL DRX setting information is A in Table 2 above) is applied is the second terminal device having the destination address "00000001". In this way, the network side device determines the resource request whose index position is 4 in the resource request information list based on the index identifier "4" corresponding to the assistance information, and by obtaining the destination address 00000011 in the resource request whose index position is 4, it can know that the terminal device to which this assistance information (i.e., the SL DRX setting information is B in Table 2 above) is applied is the second terminal device having the destination address "00000011".

[0198] In another implementation, the assistance information list has the same length as the resource request information list, and the index position of the resource request in the resource request information list is the same as the index position of the assistance information in the assistance information list. The network side device can determine an index identifier corresponding to the assistance information based on the index position of the assistance information in the assistance information list.

[0199] For example, assuming that the resource request information list (e.g., SL-TxResourceReqList-r16) reported from the first terminal device has four elements, for example as shown in the above Table 1, and the reported assistance information list is for example as shown in the above Table 3. After receiving the resource request information list and the assistance information list sent from the first terminal device, the network side device determines the resource request whose index position in the resource request information list is 2 based on the index identifier "2" corresponding to the assistance information (i.e., the position of the assistance information in the assistance information list), and obtains the destination address 00000001 in the resource request whose index position is 2, thereby being able to know that the terminal device to which this assistance information (i.e., the SL DRX setting information is A in the above Table 3) is applied is the second terminal device having the destination address "00000001". In this way, the network side device determines the resource request whose index position is 4 in the resource request information list based on the index identifier "4" corresponding to the assistance information, and by obtaining the destination address 00000011 in the resource request whose index position is 4, it can know that the terminal device to which this assistance information (i.e., the SL DRX setting information is B in Table 3 above) is applied is the second terminal device having the destination address "00000011".

[0200] In some embodiments of the present application, the assistance information in the reported assistance information list may be a paging identifier, or may be SL DRX assistance information, or may be SL DRX setting information, etc. In addition, when the content of the assistance information reported by the first terminal device to the network side device is different, the roles played by the first terminal device and the second terminal device are also different. For example, when the assistance information transmitted by the first terminal device to the network side device is a paging identifier, the first terminal device is a relay terminal device, and the second terminal device is a remote terminal device. Also, for example, when the assistance information transmitted by the first terminal device to the network side device is SL DRX assistance information, the first terminal device is a transmitting terminal device, and the second terminal device is a receiving terminal device. Also, for example, when the assistance information transmitted by the first terminal device to the network side device is SL DRX setting information, the first terminal device is a receiving terminal device, and the second terminal device is a transmitting terminal device. Each of these will be described in detail below based on the embodiments.

[0201] In some embodiments of the present application, when the assistance information is a paging identifier, the network side device can determine a paging message of the paging identifier after obtaining the destination address in the resource request, and send the paging message to the second terminal device through the first terminal device. Optionally, in the embodiments of the present application, the first terminal device is an intermediate terminal device, and the second terminal device is a remote terminal device. When the second terminal device sends a paging request to the network side device, the second terminal device sends its own paging identifier to the first terminal device. The first terminal device receives the paging identifier sent from the second terminal device, and sends the paging identifier to the network side device. The first terminal device determines the paging identifier as the assistance information of the second terminal device, and sets the paging identifier in the assistance information list to report to the network side device. After receiving the assistance information list, the network side device determines a resource request located at an index position in the resource request information list according to an index identifier corresponding to a paging identifier in the assistance information list, obtains a destination address in the resource request located at the index position, and determines that the terminal device having the destination address is a second terminal device to which the paging identifier applies, so that the network side device can send a paging message of the paging identifier to the first terminal device. The first terminal device forwards the paging message to the second terminal device.

[0202] In some embodiments of the present application, when the assistance information is sidelink discontinuous reception (SL DRX) configuration information, the network side device schedules sidelink transmission resources to the second terminal device based on the SL DRX configuration information within an activation time of the second terminal device.

[0203] Optionally, in the embodiment of the present application, the first terminal device is a receiving terminal device, and the second terminal device is a transmitting terminal device. In order to save power, the network side device (e.g., a base station) can adjust the Uu DRX so that the SL DRX and the Uu DRX overlap as much as possible based on the SL DRX setting information of the sidelink terminal device. In such a case, the first terminal device receives the SL DRX setting information sent from the second terminal device, and the second terminal device decides whether to accept the SL DRX setting information. If the first terminal device decides to accept the SL DRX setting information, the first terminal device needs to determine the SL DRX setting information as the assistance information of the second terminal device, and set the assistance information in an assistance information list to report to the network side device. After receiving the assistance information list, the network side device determines a resource request located at an index position in the resource request information list based on an index identifier corresponding to the SL DRX setting information in the assistance information list, obtains a destination address in the resource request located at the index position, and determines that the terminal device having the destination address is a second terminal device to which the SL DRX setting information applies, so that the network side device can schedule sidelink transmission resources to the second terminal device based on the SL DRX setting information within the activation time of the second terminal device.

[0204] In some embodiments of the present application, when the support information is SL DRX support information, and the SL DRX support information includes advised SL DRX setting information, the network side device determines the SL DRX setting information of the second terminal device based on the SL DRX support information.

[0205] Optionally, the first terminal device is a transmitting terminal device and the second terminal device is a receiving terminal device. In order to save power, the network side device (e.g., a base station) can adjust the Uu DRX based on the SL DRX configuration information of the sidelink terminal device, so that the SL DRX and the Uu DRX overlap as much as possible, where the SL DRX configuration information may be the SL DRX configuration information advised in the SL DRX assistance information sent from the receiving terminal device.

[0206] For example, a unicast SL DRX is sent by a transmitting terminal device (for example, a first terminal device in an embodiment of the present application) to a receiving terminal device (for example, a second terminal device in an embodiment of the present application), so that the receiving terminal device can send SL DRX assistance information to the transmitting terminal device, and the SL DRX assistance information includes the advised SL DRX setting information, so that when the transmitting terminal device is in a connected state, it reports the received SL DRX assistance information to a network side device (for example, a base station), so that the network side device (for example, a base station) determines the SL DRX setting based on the SL DRX assistance information. After receiving the assistance information list, the network side device determines the resource request located at the index position in the resource request information list based on the index identifier corresponding to the SL DRX setting information in the assistance information list, obtains the destination address in the resource request located at the index position, and the terminal device having this destination address is the second terminal device to which this SL DRX setting information is applied, so that the network side device adjusts the Uu DRX so that the SL DRX and the Uu DRX overlap as much as possible, thereby achieving power saving.

[0207] By implementing the embodiments of the present application, a mapping relationship is established between the assistance information and the destination address of the second terminal device in the resource request information list by an index identifier corresponding to the assistance information, so that the network side device identifies the second terminal to which the assistance information sent from the first terminal device applies based on this mapping relationship, thereby realizing the indication of the second terminal device to which the assistance information applies through the existing destination address field in the resource request information list, and saving the signaling overhead of reporting the assistance information.

[0208] In the above embodiments provided by the present application, the methods provided by the embodiments of the present application are described from the perspective of a terminal device (e.g., the first terminal device in the above-mentioned method embodiment) and a network side device. To realize each function in the method provided by the above-mentioned embodiment of the present application, the terminal device (e.g., the first terminal device in the above-mentioned method embodiment) and the network side device may include a hardware configuration and a software module, and each of the above functions may be realized in the form of a hardware configuration, a software module, or a hardware configuration plus a software module. Some of the above functions may be performed in the form of a hardware configuration, a software module, or a hardware configuration plus a software module.

[0211] When the communication device 100 is a terminal device (e.g., the first terminal device in the above-mentioned method embodiment): In an embodiment of the present application, the transceiver module 1001 sends a side link (SL) resource request information list and an assistance information list to the network side device, where the resource request information list includes multiple resource requests, and one resource request corresponds to one index position, and the assistance information list includes assistance information of a second terminal device and an index identifier corresponding to the assistance information, where the index identifier corresponds to the index position corresponding to the resource request.

[0213] In one possible implementation, the processing module 1002 determines an index position in the resource request information list of the resource request, and sets an index identifier corresponding to the assistance information in the assistance information list based on the index position.

[0217] When the communication device 100 is a network device: In an embodiment of the present application, the transceiver module 1001 receives a sidelink (SL) resource request information list and an assistance information list sent from a first terminal device, where the resource request information list includes multiple resource requests, each resource request corresponding to an index position, and the assistance information list includes assistance information of a second terminal device and an index identifier corresponding to the assistance information, where the index identifier corresponds to an index position corresponding to the resource request, and the processing module 1002 determines the resource request based on the index identifier and obtains a destination address in the resource request, where the terminal device having the destination address is the second terminal device.

[0220] In one implementation, the processing module 1002 further determines an index identifier corresponding to the aiding information based on an index position of the aiding information in the aiding information list.

[0221] In one possible implementation, if the assistance information is a paging identifier, the processing module 1002 further determines a paging message of the paging identifier, and the transceiver module 1001 further transmits the paging message to the second terminal device via the first terminal device.
