Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and in particular to a terminal auxiliary information reporting method and acquisition method and device thereof. BACKGROUND

[0002] In order to support direct communication between terminal devices, a direct link (also called sidelink, SL) communication mode is introduced, and the interface between the terminal devices is a PC-5 (sidelink communication) interface. According to the correspondence between the sending and receiving terminal devices, three transmission modes are supported on the sidelink, unicast, groupcast and broadcast. When the first terminal device in the connected state communicates through the sidelink, it needs to send a SidelinkUEInformation (sidelink communication terminal information) message to the network side device (such as a base station), which includes a Sidelink transmission resource request information list.

[0003] In the related art, when the first terminal device reports the sidelink transmission resource request information list to the network side device, the destination address field in the sidelink transmission resource request information list is used to indicate the identity of the second terminal device connected by unicast, but the sidelink transmission resource request information list cannot be expanded at present, so it cannot be added in the sidelink transmission resource request information list. The field used to indicate the paging identity, SL DRX auxiliary information and SL DRX configuration and other auxiliary information. If the destination address (also called identity) of the second terminal device is added in the first terminal device reporting the paging identity, SL DRX auxiliary information and SL DRX configuration and other auxiliary information, a large amount of signaling overhead will be added. Therefore, how to indicate the paging identity, SL DRX auxiliary information and SL DRX configuration and other auxiliary information to achieve the purpose of reducing signaling overhead has become a problem to be solved.

[0110] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application. Among them, in the description of the present application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B; "and / or" herein only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone.

[0111] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the embodiments of the present application. The singular forms "a" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0112] It should be understood that although the terms first, second, third, etc. may be used in the embodiments of the present application to describe various information, these information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the embodiments of the present application, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information. Depending on the context, the words "if" and "when" as used herein can be interpreted as "upon" or "when" or "in response to determining".

[0113] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0114] It should be noted that in order to support direct communication between terminal devices, a direct link (also called sidelink, SL) communication mode is introduced, and the interface between terminal devices is PC-5 (sidelink communication) interface. According to the correspondence between the sending and receiving terminal devices, three transmission modes are supported on the sidelink, unicast, groupcast and broadcast.

[0115] The first terminal device in the connected state needs to send a SidelinkUEInformation (sidelink communication terminal information) message to the network side device (such as a base station) when communicating on the sidelink, which includes a sidelink SL resource request information list. Among them, such as Figure 1As shown, each element in the sidelink SL resource request information list is a sidelink SL resource request of the second terminal device, and the resource request includes a destination address of the second terminal device, a corresponding transmission mode (including unicast, multicast and broadcast), a quality of service QoS and a target transmission frequency.

[0116] It is worth noting that a terminal device can not be directly connected with a base station at present, but can realize communication with the base station through relay of another terminal device, wherein the terminal device without connection with the base station is referred to as a remote terminal device (remote UE), and the terminal device providing relay function is referred to as a relay terminal device (relay UE), and the remote terminal device and the relay terminal device communicate through sidelink unicast.

[0117] It can be understood that the paging message sent by the network side device to the second terminal device (such as a remote terminal device) can be sent to the first terminal device (such as a relay terminal device) through dedicated signaling, and then forwarded to the second terminal device by the first 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 can be NG-5G-S-TMSI or I-RNTI.

[0118] In order to save the device power consumption of the terminal device when performing sidelink communication, sidelink discontinuous reception (Discontinuous Reception, DRX) is introduced. The receiving terminal device only listens to the physical sidelink control channel (physical sidelink control channel, PSCCH) in the active time, so as to achieve the purpose of saving energy.

[0119] The unicast sidelink discontinuous reception SL DRX configuration information is sent by the sending terminal device to the receiving terminal device, and the receiving terminal device can send SL DRX assistance information to the sending terminal device, and the SL DRX assistance information includes recommended SL DRX configuration information. If the receiving terminal device is in a connected state, the received SL DRX configuration information is reported to the base station. The base station can adjust the Uu (cellular network communication interface) DRX so that the SL DRX and the Uu DRX coincide as much as possible to achieve the purpose of power saving. If the sending terminal device is in a connected state, the received SL DRX assistance information is reported to the base station. The base station decides the SL DRX configuration according to the SL DRX assistance information.

[0120] In the related art, for example, Figure 1As shown, the first terminal device indicates the identity of the unicast-connected second terminal device by using the destination address field in the resource request in the sidelink resource request information list when reporting the sidelink resource request information list to the network side device, but the sidelink resource request information list cannot be expanded at present, and therefore the fields for indicating the paging identity, sidelink discontinuous reception (SL DRX) assistance information, and SL DRX configuration cannot be added in the sidelink resource request information list. If the destination address (also called identity) of the second terminal device is added in the reporting of the paging identity, SL DRX assistance information, and SL DRX configuration by the first terminal device, a large amount of signaling overhead will be generated. Therefore, how to indicate the paging identity, SL DRX assistance information, and SL DRX configuration to reduce the signaling overhead has become a problem to be solved.

[0121] Based on the above problems, the present application provides a terminal assistance information reporting method and acquisition method and device, which can realize the indication of the second terminal device to which the assistance information is applicable 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.

[0122] Figure 2 A schematic diagram of an architecture of a communication system provided by an embodiment of the present application is shown. The communication system can include, but is not limited to, one network device and two terminal devices, Figure 2 The number and form of the devices shown are only for example and do not limit the embodiments of the present application, and in actual applications, two or more network devices and two or more terminal devices can be included. Figure 2 The communication system shown includes one network device 201 and two terminal devices 202. The terminal device 202 is a sidelink terminal device.

[0123] It should be noted that the technical solutions of the embodiments of the present application can be applied to various communication systems. For example, long term evolution (LTE) system, 5th generation (5G) mobile communication system, 5G new radio (NR) system, or other future new mobile communication systems, etc. It should also be noted that the sidelink in the embodiments of the present application can also be referred to as sidelink or direct link.

[0124] The network device 201 in the embodiments of the present application is an entity for transmitting or receiving signals on the network side. For example, the network device 201 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network device. The network device provided by the embodiments of the present application can be composed of a central unit (CU) and a distributed unit (DU), wherein the CU can also be referred to as a control unit (control unit).

It can be known by those skilled in the art that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0128] The terminal-assisted information reporting method, acquisition method and device provided by the present application will be described in detail below with reference to the accompanying drawings.

[0129] Please refer to Figure 3 , Figure 3 The flowchart of a terminal-assisted information reporting method provided by the embodiments of the present application. It should be noted that the terminal-assisted information reporting method of the embodiments of the present application can be executed by a first terminal device. As shown in Figure 3 , the terminal-assisted information reporting method can include but is not limited to the following steps:

[0130] Step 301, sending a sidelink (SL) resource request information list and an auxiliary information list to a network side device; wherein the resource request information list includes a resource request of a second terminal device, and the resource request of the second terminal device includes a destination address of the second terminal device; the auxiliary information list includes auxiliary information, and the auxiliary information is determined by an index identifier to identify a terminal device identifier corresponding to the auxiliary information; wherein the terminal device identifier corresponding to the auxiliary information is the destination address in the resource request at the index identifier position in the resource request information list.

[0131] In some embodiments of the present application, the auxiliary information in the reported auxiliary information list can be a paging identifier, or can also be SL discontinuous reception (DRX) auxiliary information, or can also be SL DRX configuration, etc.

[0132] In an implementation manner, the length of the assistance information list can be 1. That is, the first terminal device can report an assistance information list to the network side device, and the assistance information list can include one or more assistance information. Each assistance information in the assistance information list can determine the UE identifier to which the assistance information is applicable by an index, and the UE identifier can be the destination address in the resource request at the index position in the resource request information list.

[0133] It can be understood that the first terminal device in the connected state needs to send a SidelinkUEInformation message to the network side device (such as a base station) when communicating through sidelink, which includes a sidelink SL resource request information list. Each element in the resource request information list is a resource request of a second terminal device, and the resource request includes the destination address of the second terminal device, the corresponding transmission mode (including unicast, multicast and broadcast), the quality of service QoS and the target transmission frequency. In the embodiments of the present application, the first terminal device reports the assistance information to the network side device by the index identifier corresponding to the assistance information to build the mapping relationship between the assistance information and the destination address of the second terminal device in the resource request information list, so that the network side device determines the second terminal to which the assistance information sent by the first terminal device is applicable according to the mapping relationship. Therefore, it can be seen that the indication of the second terminal device to which the assistance information is applicable is realized by the existing destination address field in the resource request information list.

[0134] It should be noted that in some embodiments of the present application, the index identifier can be set in various ways, for example, it can be carried in the corresponding assistance information, or it can also be set by the index position of the resource request in the resource request information list. The following will give examples to describe the 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 under different settings of the index identifier.

[0135] As an example of a possible implementation manner, it is assumed that the resource request information list (such as SL-TxResourceReqList-r16) reported by the first terminal device has four elements, as shown in Table 1 below:

[0136] Table 1 Elements contained in the resource request information list

[0137]

[0138] Assuming that the first terminal device needs to report the SL DRX configuration information as the auxiliary information, the reported SL DRX configuration information can be as follows: for the second terminal device with a destination address (also called an identifier) of 00000001, the SL DRX configuration information is A; for the second terminal device with a destination address (also called an identifier) of 00000011, the SL DRX configuration information is B. Due to the different setting modes of the index identifier, the form of the auxiliary information list reported by the first terminal device to the network side device will also be different.

[0139] In an implementation mode, the index identifier is carried in the corresponding auxiliary information. In this case, the first terminal device can need to set the index identifier according to the index position of the sending resource request of the second terminal device in the resource request information list. In this implementation mode, the auxiliary information list reported by the first terminal device to the network side device can be as shown in Table 2 below:

[0140] Table 2 Auxiliary information list

[0141]

[0142] Among them, as can be seen from Table 1 and Table 2, the SL-DestinationIdentity-r16 of the UE with the SL DRX configuration A in the reported auxiliary information list is the SL-DestinationIdentity-r16 of the 2nd (index identifier) entry in the resource request information list (such as SL-TxResourceReqList-r16), that is, 00000001. By analogy, the SL-DestinationIdentity-r16 of the UE with the SL DRX configuration B in the reported auxiliary information list is the SL-DestinationIdentity-r16 of the 4th (index identifier) entry in the resource request information list (such as SL-TxResourceReqList-r16), that is, 00000011.

[0143] In another implementation mode, the index identifier in the embodiment of the present application is determined by the position of the auxiliary information in the auxiliary information list. In this case, the first terminal device needs to set the auxiliary information in the same index position in the auxiliary information list according to the index position of the resource request of the second terminal device in the resource request information list; wherein the auxiliary information list and the resource request information list have the same length. If a certain destination UE has no auxiliary information, it is empty, and its entry still needs to be reserved. In this implementation mode, the auxiliary information list reported by the first terminal device to the network side device can be as shown in Table 3 below:

[0144] Table 3 Auxiliary information list

[0145]

[0146] For example, for SL DRX configuration A in Table 3, the index of A is first determined as its index position in the assistance information list, i.e., the second, and then the UE identifier of A is obtained through the index, i.e., the SL-DestinationIdentity-r16 of the UE with SL DRX configuration A in the reported assistance information list is the SL-DestinationIdentity-r16 of the second (index) entry in the resource request information list (such as SL-TxResourceReqList-r16), i.e., 00000001.

[0147] For example, for SL DRX configuration A in Table 3, the index of A is first determined as its index position in the assistance information list, i.e., the second, and then the UE identifier of A is obtained through the index, i.e., the SL-DestinationIdentity-r16 of the UE with SL DRX configuration A in the reported assistance information list is the SL-DestinationIdentity-r16 of the second (index) entry in the resource request information list (such as SL-TxResourceReqList-r16), i.e., 00000001.

[0148] In some embodiments of the present application, the assistance information in the reported assistance information list can be a paging identifier, or can also be sidelink discontinuous reception (SL DRX) assistance information, or can also be SL DRX configuration, etc. In an implementation manner, the assistance information can include a paging identifier of a second terminal device, where the second terminal device is a remote terminal device.

[0149] That is, when the first terminal device is a relay UE, the assistance information in the reported assistance information list can include a paging identifier of a second terminal device. For example, when the first terminal device is a relay UE, the relay UE needs to report the paging identifier of a second terminal device (such as 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 the relay UE forwards the paging message to the second terminal device.

[0150] In an implementation manner, the assistance information can include a sidelink discontinuous reception (SL DRX) configuration, where the sidelink discontinuous reception (SL DRX) configuration is an SL DRX configuration received by the first terminal device from a second terminal device, and the first terminal device accepts the SL DRX configuration.

[0151] That is, when the first terminal device receives the SL DRX configuration sent by the second terminal device, and the first terminal device accepts the SL DRX configuration, the assistance information in the assistance information list reported by the first terminal device can also include the SL DRX configuration.

[0152] In an implementation manner, the assistance information can include received SL DRX assistance information, wherein the SL DRX assistance information is SL DRX assistance information received by the first terminal device and sent by the second terminal device.

[0153] That is, when the first terminal device receives the SL DRX assistance information sent by the second terminal device, the assistance information in the assistance information list reported by the first terminal device can also include the received SL DRX assistance information.

[0154] By implementing the embodiments of the present application, the identity of the terminal device UE to which the terminal assistance information is applicable can be determined by the index identifier when reporting the terminal assistance information, and the identity of the terminal device UE is the destination address in the sending resource request at the index identifier position in the resource request information list. As can be seen, the embodiments of the present application build a mapping relationship between the assistance information and the destination address of the opposite terminal device UE in the resource request information list through the index identifier, thereby realizing the indication to the opposite terminal device when reporting the terminal assistance information, and the signaling overhead of reporting the terminal assistance information can be saved.

[0155] Please refer to Figure 4 , Figure 4 A flowchart of a terminal assistance information reporting method provided by an embodiment of the present application is shown. It should be noted that the terminal assistance information reporting method of the embodiments of the present application can be executed by a first terminal device. As shown in Figure 4 , the terminal assistance information reporting method can include but is not limited to the following steps:

[0156] Step 401, sending a sidelink SL resource request information list and an assistance information list to a network side device, wherein the resource request information list includes a plurality of resource requests, and one resource request corresponds to one index position, the assistance information list includes assistance information of a second terminal device, and an index identifier corresponding to the assistance information, wherein the index identifier corresponds to the index position corresponding to the resource request.

[0157] In some embodiments of the present application, the assistance information in the assistance information list can be a paging identifier, or can also be SL discontinuous reception SL DRX assistance information, or can also be SL DRX configuration, etc.

[0158] In an implementation manner, the length of the assistance information list can be 1. That is, the first terminal device can further send, to the network side device, an assistance information list in addition to the sidelink (SL) resource request information list, the assistance information list can include assistance information of one or more second terminal devices, and the assistance information corresponds to an index identifier, which corresponds to an index position of the resource request in the resource request information list. 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 the assistance information in the assistance information list applies through the existing destination address field in the resource request information list, and the signaling overhead of reporting the assistance information can be saved.

[0159] It can be understood that the first terminal device in the connected state needs to send a SidelinkUEInformation (sidelink communication terminal information) message to the network side device (such as a base station) when performing sidelink communication, and the SidelinkUEInformation message includes a sidelink (SL) resource request information list. Each element in the resource request information list is a resource request of a second terminal device, and the resource request includes the destination address of the second terminal device, the corresponding transmission mode (including unicast, multicast and broadcast), the quality of service (QoS) and the target transmission frequency. In the embodiments of the present application, the first terminal device reports the assistance information to the network side device by using the index identifier corresponding to the assistance information to build a mapping relationship between the assistance information and the destination address of the second terminal device in the resource request information list, so that the network side device determines the second terminal to which the assistance information sent by the first terminal device applies according to the mapping relationship. Therefore, the indication of the second terminal device to which the assistance information applies can be realized through the existing destination address field in the resource request information list.

[0160] It should be noted that in some embodiments of the present application, the index identifier can be set in various ways, for example, it can be carried in the corresponding assistance information, or the index identifier corresponding to the assistance information can be set through the index position of the resource request in the resource request information list. Examples will be given below to describe the mapping relationship between the assistance information and the destination address of the second terminal device in the resource request information list through the index identifier under different settings of the index identifier.

[0161] As an example of a possible implementation manner, it is assumed that the resource request information list (such as SL-TxResourceReqList-r16) reported by the first terminal device has four elements, as shown in Table 1 above. It is assumed that the first terminal device needs to report SL DRX configuration information as the auxiliary information, and the reported SL DRX configuration information can be as follows: for the second terminal device with a destination address (also called an identifier) of 00000001, the SL DRX configuration information is A; for the second terminal device with a destination address (also called an identifier) of 00000011, the SL DRX configuration information is B. Due to the different setting manners of the index identifier, the form of the auxiliary information list reported by the first terminal device to the network side device will also be different.

[0162] In an implementation manner, the index identifier is carried in the corresponding auxiliary information. In this case, the first terminal device can determine the index position of the resource request in the resource request information list, and set the index identifier corresponding to the auxiliary information in the auxiliary information list according to the index position. After setting the index identifier corresponding to the auxiliary information in the auxiliary information list according to the index position, the first terminal device can send the set auxiliary information list and the resource request information list to the network side device.

[0163] For example, the form of the auxiliary information list reported by the first terminal device to the network side device can be as shown in Table 2 above. As can be seen from Table 1 and Table 2, the destination address of the second terminal device to which the SL DRX configuration information A in the reported auxiliary information list applies is the destination address with an index position of 2 in the resource request information list (such as SL-TxResourceReqList-r16), that is, 00000001. By analogy, the destination address of the second terminal device to which the SL DRX configuration B in the reported auxiliary information list applies is the destination address with an index position of 4 in the resource request information list (such as SL-TxResourceReqList-r16), that is, 00000011. After receiving the resource request information list and the auxiliary information list sent by the first terminal device, the network side device can determine the resource request in the index position in the resource request information list according to the index identifier corresponding to the auxiliary information in the auxiliary information list, and obtain the destination address in the resource request in the index position, wherein the terminal device with the destination address is the second terminal device to which the auxiliary information applies.

[0164] For example, assuming that the resource request information list sent by the first terminal device is as shown in Table 1 above, and the auxiliary information list sent is as shown in Table 2 above, the network side device can determine the resource request in the resource request information list at the index position 2 according to the index identification "2" corresponding to the auxiliary information, so that the network side device can understand that the terminal device to which the auxiliary information (i.e., the SL DRX configuration information is A in Table 2 above) applies is the second terminal device with the destination address "00000001". Similarly, the network side device can determine the resource request in the resource request information list at the index position 4 according to the index identification "4" corresponding to the auxiliary information, so that the network side device can understand that the terminal device to which the auxiliary information (i.e., the SL DRX configuration information is B in Table 2 above) applies is the second terminal device with the destination address "00000011".

[0165] In another implementation manner, the auxiliary information list has the same length as the resource request information list; the index position of the resource request in the resource request information list is the same as the index position of the auxiliary information in the auxiliary information list. The index identification corresponding to the auxiliary information can be the index position of the auxiliary information in the auxiliary information list. That is, the first terminal device needs to set the auxiliary information of the second terminal device in the auxiliary information list at the same index position according to the index position of the resource request of the second terminal device in the resource request information list. If a second terminal device has no auxiliary information, the corresponding position in the auxiliary information list is empty.

[0166] For example, the form of the auxiliary information list reported by the first terminal device to the network side device can be as shown in Table 3 below:

[0167] Table 3 Auxiliary information list

[0168]

[0169] That is, the length of the auxiliary information list set by the first terminal device is the same as the length of the resource request information list, and both are 4. It is assumed that the terminal device to which the SL DRX configuration information A is applicable is the second terminal device with the destination address 00000001, and the terminal device to which the SL DRX configuration information B is applicable is the second terminal device with the destination address 00000011. The first terminal device needs to set the SL DRX configuration information A at the position with the index position 2 in the auxiliary information list according to the index position (such as 2) of the resource request of the second terminal device in the resource request information list. In this way, the first terminal device needs to set the SL DRX configuration information B at the position with the index position 4 in the auxiliary information list according to the index position (such as 4) of the resource request of the second terminal device in the resource request information list. For other second terminal devices without auxiliary information in the resource request information list, the corresponding positions in the auxiliary information list are empty, that is, the form of the auxiliary information list set by the first terminal device can be as shown in Table 3 above. After the first terminal device sets the auxiliary information at the same index position in the auxiliary information list according to the index position of the resource request in the resource request information list, the first terminal device sends the set auxiliary information list and the resource request information list to the network side device.

[0170] In this example, after receiving the resource request information list and the auxiliary information list sent by the first terminal device, the network side device can determine the resource request at the index position in the resource request information list according to the index identifier corresponding to the auxiliary information in the auxiliary information list, and obtain the destination address in the resource request at the index position, where the terminal device with the destination address is the second terminal device to which the auxiliary information is applicable. For example, it is assumed that the resource request information list sent by the first terminal device is as shown in Table 1 above, and the auxiliary information list sent by the first terminal device is as shown in Table 3 above. The network side device can determine the resource request at the index position 2 in the resource request information list according to the index identifier “2” (that is, the position of the auxiliary information in the auxiliary information list), so that the network side device can understand that the terminal device to which the auxiliary information (that is, the SL DRX configuration information A in Table 3 above) is applicable is the second terminal device with the destination address “00000001”. In this way, the network side device can determine the resource request at the index position 4 in the resource request information list according to the index identifier “4”, so that the network side device can understand that the terminal device to which the auxiliary information (that is, the SL DRX configuration information B in Table 3 above) is applicable is the second terminal device with the destination address “00000011”.

[0171] By implementing the embodiments of the present application, the mapping relationship between the auxiliary information and the destination address of the second terminal device in the resource request information list is established through the index identification corresponding to the auxiliary information, so that the network side device determines the second terminal to which the auxiliary information sent by the first terminal device is applicable according to the mapping relationship. As can be seen, by using the existing destination address field in the resource request information list, the indication of the second terminal device to which the auxiliary information is applicable is realized, which can save the signaling overhead of reporting the auxiliary information.

[0172] It should be noted that in some embodiments of the present application, the auxiliary information in the reported auxiliary information list can be a paging identifier, or can also be SL DRX auxiliary information, or can also be SL DRX configuration information, etc. It can be understood that the content of the auxiliary information reported by the first terminal device to the network side device is different, and the roles played by the first terminal device and the second terminal device are also different. For example, when the auxiliary information sent 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. For another example, when the auxiliary information sent by the first terminal device to the network side device is SL DRX auxiliary information, the first terminal device is a sending terminal device, and the second terminal device is a receiving terminal device. For another example, when the auxiliary information sent by the first terminal device to the network side device is SL DRX configuration information, the first terminal device is a receiving terminal device, and the second terminal device is a sending terminal device. The following will be described in detail in combination with embodiments.

[0173] Please refer to Figure 5 , Figure 5 The flowchart of another terminal auxiliary information reporting method provided by the embodiments of the present application. It should be noted that the terminal auxiliary information reporting method of the embodiments of the present application can be executed by the first terminal device. Wherein, the auxiliary information is a paging identifier. As shown in Figure 5 , the terminal auxiliary information reporting method can include but not limited to the following steps.

[0174] Step 501, receiving the paging identifier sent by the second terminal device.

[0175] Optionally, in the embodiments of the present application, the first terminal device is a relay 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 by the second terminal device, so that the first terminal device sends the paging identifier to the network side device, so that the network side device sends the paging message of the paging identifier to the second terminal device through the first terminal device.

[0176] Step 502, determining the paging identifier as the auxiliary information of the second terminal device.

[0177] Optionally, the first terminal device can determine the paging identifier as the assistance information of the second terminal device after receiving the paging identifier sent by the second terminal device. Since the first terminal device also needs to report the resource request information list to the network side device to realize the network side device to configure the sidelink resource 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 the paging identifier is applicable to.

[0178] In an implementation manner, after the first terminal device determines the paging identifier as the assistance information of the second terminal device, the first terminal device can set an index identifier corresponding to the paging identifier in the assistance information list according to the index position of the sidelink resource request of the second terminal device in the resource request information list, so as to set the paging identifier and the index identifier corresponding thereto in the assistance information list.

[0179] For example, it is assumed that the resource request information list (such as SL-TxResourceReqList-r16) that the first terminal device needs to report has four elements, as shown in Table 1 above. It is assumed that the first terminal device receives the paging identifier C sent by the second terminal device with the destination address “00000001” and the paging identifier D sent by the second terminal device with the destination address “00000011” as the assistance information. The first terminal device can determine that the index position of the resource request of the second terminal device with the destination address “00000001” in the resource request information list is 2, and set the index identifier corresponding to the paging identifier C in the assistance information list according to the index position, that is, the index identifier is 2. The form of the paging identifier C and the index identifier in the assistance information list can be as shown in Table 4 below. The first terminal device can determine that the index position of the resource request of the second terminal device with the destination address “00000011” in the resource request information list is 4, and set the index identifier corresponding to the paging identifier D in the assistance information list according to the index position, that is, the index identifier is 4. The form of the paging identifier D and the index identifier in the assistance information list can be as shown in Table 4 below. The first terminal device sets the paging identifier C and the index identifier corresponding thereto and the paging identifier D and the index identifier corresponding thereto in the assistance information list, and the form of the assistance information list can be as shown in Table 4.

[0180] Table 4 Assistance information list

[0181]

[0182] In another implementation, after determining the paging identifier as the assistance information of the second terminal device, the first terminal device can set the corresponding assistance information in the assistance information list according to the index position of the resource request information in the resource request information list; wherein the index identifier corresponding to the assistance information corresponds to the index position of the assistance information in the assistance information list; the assistance information list and the resource request information list have the same length.

[0183] For example, assuming that the first terminal device needs to report a sidelink (SL) resource request information list (such as SL-TxResourceReqList-r16) with four elements, as shown in Table 1 above. Assuming that the first terminal device receives the paging identifier C sent by the second terminal device with the destination address "00000001" and the paging identifier D sent by the second terminal device with the destination address "00000011". The first terminal device can determine that the resource request of the second terminal device with the destination address "00000001" has an index position of 2 in the resource request information list, and set the paging identifier C in the same index position in the assistance information list according to the index position, as shown in Table 5 below. The first terminal device can determine that the resource request of the second terminal device with the destination address "00000011" has an index position of 4 in the resource request information list, and set the paging identifier D in the same index position in the assistance information list according to the index position, as shown in Table 5 below.

[0184] Table 5 Assistance information list

[0185]

[0186] Step 503, sending the sidelink (SL) resource request information list and the assistance information list to the network side device.

[0187] In the embodiments of the present application, the resource request information list includes a plurality of resource requests, and each resource request corresponds to an index position. The assistance information list includes assistance information of the second terminal device, and an index identifier corresponding to the assistance information, wherein the index identifier corresponds to the index position of the resource request.

[0188] That is, after receiving the paging identifier sent by the second terminal device, the first terminal device can determine the paging identifier as the second terminal device's assistance information, and establish a mapping relationship between the assistance information and the second terminal device's destination address in the resource request information list through the index identifier corresponding to the assistance information, so that the network side device determines the second terminal to which the assistance information sent by the first terminal device applies according to the mapping relationship. As can be seen, through the existing destination address field in the resource request information list, the indication of the second terminal device to which the assistance information applies is realized, which can save the signaling overhead of reporting the assistance information.

[0189] Please refer to Figure 6 , Figure 6 A flowchart of another terminal assistance information reporting method provided by the embodiments of the present application is shown. It should be noted that the terminal assistance information reporting method of the embodiments of the present application can be executed by a first terminal device. Wherein, the assistance information is SL DRX configuration information. As shown in Figure 6 , the terminal assistance information reporting method can include but is not limited to the following steps.

[0190] Step 601, receiving SL DRX configuration information sent by a second terminal device.

[0191] Optionally, in the embodiments of the present application, the first terminal device is a receiving terminal device, and the second terminal device is a sending terminal device. In order to achieve the purpose of power saving, the network side device (such as a base station) can adjust Uu DRX according to the SL DRX configuration information of the sidelink terminal device, so that SL DRX and Uu DRX coincide as much as possible to achieve the purpose of power saving. In this scenario, the first terminal device will receive the SL DRX configuration information sent by the second terminal device, and the second terminal device will determine whether to accept the SL DRX configuration information. When the first terminal device determines to accept the SL DRX configuration information, the first terminal device needs to report the SL DRX configuration information to the network side device, so that the network side device adjusts Uu DRX, so that SL DRX and Uu DRX coincide as much as possible to achieve the purpose of power saving.

[0192] Step 602, determining the SL DRX configuration information as the second terminal device's assistance information.

[0193] Optionally, after receiving the SL DRX configuration information sent by the second terminal device, the first terminal device can determine the SL DRX configuration information as the assistance information of the second terminal device. Since the first terminal device also needs to report the resource request information list to the network side device to realize the network side device to configure the sidelink resource 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 configuration information.

[0194] When the assistance information is the SL DRX configuration information, the implementation manner of the setting of the assistance information list is similar to that when the assistance information is the paging identifier. In an implementation manner, after the first terminal device determines the SL DRX configuration information as the assistance information of the second terminal device, the first terminal device can set the index identifier corresponding to the SL DRX configuration information in the assistance information list according to the index position of the sidelink resource request of the second terminal device in the resource request information list, so as to set the SL DRX configuration information and the index identifier corresponding thereto in the assistance information list.

[0195] In another implementation manner, after the first terminal device determines the SL DRX configuration information as the assistance information of the second terminal device, the first terminal device can set the assistance information in the same index position in the assistance information list according to the index position of the resource request in the resource request information list; wherein the index identifier corresponding to the assistance information is the index position of the assistance information in the assistance information list; and the assistance information list has the same length as the resource request information list.

[0196] In step 603, the sidelink SL resource request information list and the assistance information list are sent to the network side device.

[0197] In the embodiments of the present application, the resource request information list includes a plurality of resource requests, and one resource request corresponds to one index position; the assistance information list includes the assistance information of the second terminal device and the index identifier corresponding to the assistance information, wherein the index identifier corresponds to the index position corresponding to the resource request.

[0198] That is, after receiving the SL DRX configuration information sent by the second terminal device, the first terminal device can determine the SL DRX configuration information as the assistance information of the second terminal device when in the connected state, and establish a mapping relationship between the assistance information and the destination address of the second terminal device in the resource request information list through the index identification corresponding to the assistance information, so that the network side device determines the second terminal to which the assistance information sent by the first terminal device applies according to the mapping relationship. It can be seen that, by using the existing destination address field in the resource request information list, the indication of the second terminal device to which the assistance information applies is realized, and the signaling overhead of reporting the assistance information can be saved.

[0199] Please refer to Figure 7 , Figure 7 The flowchart of another terminal assistance information reporting method provided by the embodiments of the present application is shown. It should be noted that the terminal assistance information reporting method of the embodiments of the present application can be executed by a first terminal device. Wherein, the assistance information is SL DRX assistance information. As shown in Figure 7 , the terminal assistance information reporting method can include but is not limited to the following steps.

[0200] Step 701, receiving SL DRX assistance information sent by a second terminal device; the SL DRX assistance information includes suggested SL DRX configuration information.

[0201] Optionally, in the embodiments of the present application, the first terminal device is a sending terminal device, and the second terminal device is a receiving terminal device. In order to achieve the purpose of power saving, the network side device (such as a base station) can adjust the Uu DRX according to the SL DRX configuration information of the sidelink terminal device, so that the SL DRX and the Uu DRX coincide as much as possible to achieve the purpose of power saving, wherein the SL DRX configuration information can be the suggested SL DRX configuration information in the SL DRX assistance information sent by the receiving terminal device.

[0202] For example, since the unicast SL DRX is sent by the sending terminal device (such as the first terminal device described in the embodiments of the present application) to the receiving terminal device (such as the second terminal device described in the embodiments of the present application), the receiving terminal device can send SL DRX assistance information to the sending terminal device, and the SL DRX assistance information includes suggested SL DRX configuration information, so that the sending terminal device reports the received SL DRX assistance information to the network side device (such as a base station) when in the connected state, so that the network side device (such as a base station) decides the SL DRX configuration according to the SL DRX assistance information.

[0203] Step 702, determining the SL DRX assistance information as the assistance information of the second terminal device.

[0204] Optionally, after receiving the SL DRX assistance information sent by 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 also needs to report the resource request information list to the network side device to realize the network side device to configure the sidelink resource 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.

[0205] When the assistance information is the SL DRX assistance information, the implementation manner of the setting of the assistance information list is similar to that when the assistance information is the paging identifier. In an implementation manner, after the first terminal device takes the SL DRX assistance information as the assistance information of the second terminal device, the first terminal device can set the index identifier corresponding to the SL DRX assistance information in the assistance information list according to the index position of the sidelink resource request of the second terminal device in the resource request information list and according to the index position in the assistance information list, so as to set the SL DRX assistance information and the index identifier corresponding thereto in the assistance information list.

[0206] In another implementation manner, after the first terminal device takes the SL DRX assistance information as the assistance information of the second terminal device, the first terminal device can set the corresponding assistance information in the same index position in the assistance information list according to the index position of the resource request in the resource request information list. The index identifier corresponding to the assistance information corresponds to the index position of the assistance information in the assistance information list. The assistance information list and the resource request information list have the same length.

[0207] In step 703, the sidelink SL resource request information list and the assistance information list are sent to the network side device.

[0208] In the embodiments of the present application, the resource request information list includes a plurality of resource requests, and one resource request corresponds to one index position. The assistance information list includes the assistance information of the second terminal device and the index identifier corresponding to the assistance information. The index identifier corresponds to the index position corresponding to the resource request.

[0209] That is, after receiving the SL DRX assistance information sent by the second terminal device, the first terminal device can determine the SL DRX assistance information as the assistance information of the second terminal device when in the connected state, and establish a mapping relationship between the assistance information and the destination address of the second terminal device in the resource request information list through the index identification corresponding to the assistance information, so that the network side device determines the second terminal to which the assistance information sent by the first terminal device applies according to the mapping relationship. It can be seen that, by using the existing destination address field in the resource request information list, the indication of the second terminal device to which the assistance information applies is realized, and the signaling overhead of reporting the assistance information can be saved.

[0210] It can be understood that the above embodiments are from the first terminal device side to describe the implementation of the terminal assistance information reporting method of the embodiments of the present application. The embodiments of the present application also propose a terminal assistance information acquisition method. The implementation of the terminal assistance information acquisition method will be described from the network side device side. Please refer to Figure 8 , Figure 8 The flowchart of a terminal assistance information acquisition method provided by the embodiments of the present application. It should be noted that the terminal assistance information acquisition method of the embodiments of the present application can be executed by the network side device. As shown in Figure 8 , the terminal assistance information acquisition method can include but is not limited to the following steps.

[0211] Step 801, receiving the sidelink SL resource request information list and the assistance information list sent by the first terminal device; wherein the resource request information list includes the resource request of the second terminal device, and the resource request of the second terminal device includes the destination address of the second terminal device; the assistance information list includes assistance information, and the assistance information is determined by an index identification to determine the terminal device identification corresponding to the assistance information; wherein the terminal device identification corresponding to the assistance information is the destination address in the resource request at the index identification position in the resource request information list.

[0212] In some embodiments of the present application, the assistance information in the reported assistance information list can be a paging identifier, or can also be sidelink discontinuous reception SL DRX assistance information, or can also be SL DRX configuration, etc.

[0213] In an implementation manner, the length of the auxiliary information list can be 1. That is, the first terminal device can report the auxiliary information list to the network side device. The network side device can receive the auxiliary information list sent by the first terminal device, which can include one or more auxiliary information. The auxiliary information list can include one or more auxiliary information, and each auxiliary information in the auxiliary information list can determine the UE identifier to which the auxiliary information is applicable by an index, which can be the destination address in the resource request information list at the index identifier position.

[0214] It can be understood that the first terminal device in the connected state needs to send a SidelinkUEInformation message to the network side device (such as a base station) when communicating through sidelink, which includes a sidelink SL resource request information list. Each element in the resource request information list is a resource request of a second terminal device, which includes the destination address of the second terminal device, the corresponding transmission mode (including unicast, multicast and broadcast), the quality of service QoS and the target transmission frequency. In the embodiments of the present application, the first terminal device reports the auxiliary information to the network side device by the index identifier corresponding to the auxiliary information to build the mapping relationship between the auxiliary information and the destination address of the second terminal device in the resource request information list, so that the network side device determines the second terminal to which the auxiliary information sent by the first terminal device is applicable according to the mapping relationship. It can be seen that the indication of the second terminal device to which the auxiliary information is applicable is realized by the existing destination address field in the resource request information list.

[0215] It should be noted that in some embodiments of the present application, the index identifier can be set in various ways, for example, it can be carried in each auxiliary information, or it can also be determined by the position of the auxiliary information in the auxiliary information list. The setting method of the index identifier can be described in the implementation manner of each embodiment described above, which will not be repeated here.

[0216] In some embodiments of the present application, the auxiliary information in the reported auxiliary information list can be a paging identifier, or it can also be a sidelink discontinuous reception SL DRX auxiliary information, or it can also be a SL DRX configuration, etc. In an implementation manner, when the auxiliary information in the reported auxiliary information list is a paging identifier, the network side device can send paging information with the destination address being the paging identifier to the terminal device reporting the auxiliary information list.

[0217] That is, when the first terminal device is a relay UE, the assistance information in the reported assistance information list can include a paging identity of the second terminal device. For example, when the first terminal device is a relay UE, the relay UE needs to report the paging identity of the second terminal device (such as a remote UE) to the network side device, so that the network side device sends the paging message sent to the remote UE to the relay UE, and the relay UE forwards the paging message to the remote UE.

[0218] In an implementation manner, when the assistance information in the reported assistance information list is a sidelink discontinuous reception (SL DRX) configuration, the network side device can schedule sidelink transmission resources to the second terminal device corresponding to the destination address within the active time of the second terminal device.

[0219] 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 is applicable to the SL-DestinationIdentity-r16 of the 2nd (index identifier) entry in the resource request information list (such as SL-TxResourceReqList-r16), that is, the terminal device with the index identifier of 00000001, the network side device can schedule sidelink transmission resources to the terminal device with the destination address of 00000001 within the active time of the terminal device.

[0220] In an implementation manner, when the assistance information in the reported assistance information list is SL DRX assistance information, the network side device can determine the SL DRX configuration of the second terminal device corresponding to the destination address according to the SL DRX assistance information.

[0221] As an example, the SL DRX assistance information can include a recommended SL DRX configuration. For example, assuming that the network side device receives the assistance information in the assistance information list reported by the first terminal device as SL DRX assistance information, the SL DRX assistance information includes a recommended SL DRX configuration A, and the index identifier corresponding to the assistance information is 2. Assuming that the network side device determines that the destination address of the resource request in the 2nd (index identifier) position in the resource request information list is “00000001” according to the index identifier, the network side device can determine that the SL DRX assistance information is applicable to the terminal device with the destination address of “00000001”, and the network side device can determine the SL DRX configuration of the terminal device with the destination address of “00000001” as A according to the SL DRX assistance information.

[0222] By implementing the embodiments of the present application, the identity of the terminal device UE to which the terminal assistance information is applicable can be determined by the index identifier when the terminal assistance information is reported, and the identity of the terminal device UE is the destination address in the resource request at the index identifier position in the resource request information list. As can be seen, the embodiments of the present application build a mapping relationship between the assistance information and the destination address of the opposite terminal device UE in the resource request information list through the index identifier, thereby realizing the indication of the opposite terminal device when the terminal assistance information is reported, and the signaling overhead of reporting the terminal assistance information can be saved.

[0223] Please refer to Figure 9 , Figure 9 A flowchart of a terminal assistance information acquisition method provided by the embodiments of the present application is shown. It should be noted that the terminal assistance information acquisition method of the embodiments of the present application can be executed by a network side device. As shown in Figure 9 , the terminal assistance information acquisition method can include but is not limited to the following steps.

[0224] Step 901, receiving a sidelink (SL) resource request information list and an assistance information list sent by a first terminal device; wherein the resource request information list includes a plurality of resource requests, and one resource request corresponds to one index position, the assistance information list includes assistance information of a second terminal device, and an index identifier corresponding to the assistance information, wherein the index identifier corresponds to the index position corresponding to the resource request.

[0225] In the embodiments of the present application, the implementation manner of the first terminal device sending the resource request information list and the assistance information list can be implemented by any one of the implementation manners in the embodiments of the present application, and the embodiments of the present application do not limit this, and will not be repeated.

[0226] Step 902, determining the resource request according to the index identifier.

[0227] Optionally, after receiving the resource request information list and the assistance information list sent by the first terminal device, the network side device can determine the resource request at the index position in the resource request information list according to the index identifier corresponding to the assistance information in the assistance information list.

[0228] Step 903, obtaining the destination address in the resource request, wherein the terminal device with the destination address is the second terminal device.

[0229] Optionally, after determining the resource request, the network side device can obtain the destination address from the resource request, and the terminal device with the destination address is the second terminal device to which the assistance information is applicable.

[0230] It should be noted that due to different setting modes of the index identifier, the form of the auxiliary information list will also be different. For example, as shown in Table 2 and Table 4 described above, the index identifier can be carried in the corresponding auxiliary information. For another example, as shown in Table 1, Table 3 and Table 5 described above, the auxiliary information list has the same length as the resource request information list, and the index identifier corresponding to the auxiliary information can be understood as the index position of the auxiliary information in the auxiliary information list, that is, the network side device can also determine the index identifier corresponding to the auxiliary information through the position of the auxiliary information in the auxiliary information list, so that the network side device can determine the resource request in the index position in the resource request information list according to the index identifier.

[0231] In an implementation mode, the index identifier is carried in the corresponding auxiliary information. For example, it is assumed that the resource request information list (such as SL-TxResourceReqList-r16) reported by the first terminal device has four elements, as shown in Table 1 described above, and the reported auxiliary information list is as shown in Table 2 described above. After receiving the resource request information list and the auxiliary information list reported by the first terminal device, the network side device can determine the resource request in the index position 2 in the resource request information list according to the index identifier “2” corresponding to the auxiliary information, and obtain the destination address “00000001” in the resource request in the index position 2, so that the network side device can understand that the terminal device applicable to the auxiliary information (that is, the SL DRX configuration information is A in Table 2 described above) is the second terminal device with the destination address “00000001”. By analogy, the network side device can determine the resource request in the index position 4 in the resource request information list according to the index identifier “4” corresponding to the auxiliary information, and obtain the destination address “00000011” in the resource request in the index position 4, so that the network side device can understand that the terminal device applicable to the auxiliary information (that is, the SL DRX configuration information is B in Table 2 described above) is the second terminal device with the destination address “00000011”.

[0232] In another implementation mode, the auxiliary information list has the same length as the resource request information list; the index position of the resource request in the resource request information list is the same as the index position of the auxiliary information in the auxiliary information list. The network side device can determine the index identifier corresponding to the auxiliary information according to the index position of the auxiliary information in the auxiliary information list.

[0233] For example, it is assumed that the resource request information list (such as SL-TxResourceReqList-r16) reported by the first terminal device has four elements, as shown in Table 1 above, and the reported auxiliary information list is as shown in Table 3 above. After receiving the resource request information list and the auxiliary information list sent by the first terminal device, the network side device can determine the resource request at the index position 2 in the resource request information list according to the index identification "2" of the corresponding auxiliary information (i.e. the position of the auxiliary information in the auxiliary information list), and obtain the destination address 00000001 in the resource request at the index position 2, so that the network side device can understand that the terminal device applicable to the auxiliary information (i.e. the SL DRX configuration information A in Table 3 above) is the second terminal device with the destination address "00000001". By analogy, the network side device can determine the resource request at the index position 4 in the resource request information list according to the index identification "4" of the corresponding auxiliary information, and obtain the destination address 00000011 in the resource request at the index position 4, so that the network side device can understand that the terminal device applicable to the auxiliary information (i.e. the SL DRX configuration information B in Table 3 above) is the second terminal device with the destination address "00000011".

[0234] It should be noted that in some embodiments of the present application, the auxiliary information in the reported auxiliary information list can be a paging identifier, or can also be SL DRX auxiliary information, or can also be SL DRX configuration information, etc. It can be understood that the different contents of the auxiliary information reported by the first terminal device to the network side device will result in different roles played by the first terminal device and the second terminal device. For example, when the auxiliary information sent 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. For another example, when the auxiliary information sent by the first terminal device to the network side device is SL DRX auxiliary information, the first terminal device is a sending terminal device and the second terminal device is a receiving terminal device. For another example, when the auxiliary information sent by the first terminal device to the network side device is SL DRX configuration information, the first terminal device is a receiving terminal device and the second terminal device is a sending terminal device. The following will be described in detail in combination with embodiments.

[0235] 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 a relay 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 by the second terminal device, so that the first terminal device 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 can determine the resource request in the index position in the resource request information list according to the index identifier corresponding to the paging identifier in the assistance information list, and obtain the destination address in the resource request in the index position. The terminal device with the destination address is the second terminal device to which the paging identifier is applied, so that the network side device can send the paging message of the paging identifier to the first terminal device. The first terminal device forwards the paging message to the second terminal device.

[0236] 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 according to the SL DRX configuration information within the activation time of the second terminal device.

[0237] Optionally, in the embodiments of the present application, the first terminal device is a receiving terminal device, and the second terminal device is a sending terminal device. In order to achieve the purpose of power saving, the network side device (such as a base station) can adjust the Uu DRX according to the SL DRX configuration information of the sidelink terminal device, so that the SL DRX and the Uu DRX coincide as much as possible to achieve the purpose of power saving. In this scenario, the first terminal device will receive the SL DRX configuration information sent by the second terminal device, and the second terminal device will determine whether to accept the SL DRX configuration information. When the first terminal device determines to accept the SL DRX configuration information, the first terminal device needs to determine the SL DRX configuration information as the assistance information of the second terminal device, and set the assistance information in the assistance information list to report to the network side device. After receiving the assistance information list, the network side device can determine the resource request in the index position in the resource request information list according to the index identifier corresponding to the SL DRX configuration information in the assistance information list, and obtain the destination address in the resource request in the index position. The terminal device with the destination address is the second terminal device to which the SL DRX configuration information is applied, so that the network side device can schedule sidelink transmission resources to the second terminal device within the active time of the second terminal device according to the SL DRX configuration information.

[0238] In some embodiments of the present application, when the assistance information is SL DRX assistance information including recommended SL DRX configuration information, the network side device determines the SL DRX configuration information of the second terminal device according to the SL DRX assistance information.

[0239] Optionally, the first terminal device is a sending terminal device, and the second terminal device is a receiving terminal device. In order to achieve the purpose of power saving, the network side device (such as a base station) can adjust the Uu DRX according to the SL DRX configuration information of the sidelink terminal device, so that the SL DRX and the Uu DRX coincide as much as possible to achieve the purpose of power saving, wherein the SL DRX configuration information can be the recommended SL DRX configuration information in the SL DRX assistance information sent by the receiving terminal device.

[0240] For example, since the SL DRX is sent by the sending terminal device (e.g., the first terminal device in the embodiments of the present application) to the receiving terminal device (e.g., the second terminal device in the embodiments of the present application), the receiving terminal device can send SL DRX assistance information to the sending terminal device, where the SL DRX assistance information includes recommended SL DRX configuration information, so that the sending terminal device reports the received SL DRX assistance information to the network side device (e.g., the base station) when in the connected state, so that the network side device (e.g., the base station) determines the SL DRX configuration according to the SL DRX assistance information. After the network side device receives the assistance information list, the network side device can determine the resource request in the index position in the resource request information list according to the index identifier corresponding to the SL DRX configuration information in the assistance information list, and obtain the destination address in the resource request in the index position. The terminal device with the destination address is the second terminal device to which the SL DRX configuration information is applicable, so that the network side device adjusts the Uu DRX to make the SL DRX and the Uu DRX coincide as much as possible to achieve the purpose of power saving.

[0241] By implementing the embodiments of the present application, the mapping relationship between the assistance information and the destination address of the second terminal device in the resource request information list is established through the index identifier corresponding to the assistance information, so that the network side device determines the second terminal device to which the assistance information sent by the first terminal device is applicable according to the mapping relationship. As can be seen, by using the existing destination address field in the resource request information list, the indication of the second terminal device to which the assistance information is applicable is realized, which can save the signaling overhead of reporting the assistance information.

[0242] In the above embodiments of the present application, the methods provided by the embodiments of the present application are introduced from the perspective of the terminal device (e.g., the first terminal device in the above method embodiments) and the network side device.
