The following description describes the New Radio (NR) system for illustrative purposes and uses NR terms in most of the following descriptions, but these technologies may also be applied to applications other than NR system applications, such as the 6th Generation (6G) communication system.

[0019] FIG. 1 shows a block diagram of a wireless communication system to which an embodiment of the present application is applicable. The wireless communication system includes a terminal 11 and a network-side device 12. Here, the terminal 11 may also be referred to as a terminal device or a user equipment (UE). The terminal 11 may be a terminal-side device such as a mobile phone, a tablet personal computer, a laptop computer (or called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), a wearable device, or an in-vehicle device (VUE), a pedestrian terminal (PUE), etc. The wearable device includes a bracelet, earphones, glasses, etc. It should be noted that the specific type of the terminal 11 in the embodiment of the present application is not limited. The network-side device 12 may be a base station or a core network. Here, the base station may be referred to as a Node B, an evolved Node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting receiving point (TRP), or other appropriate terms in the art. As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that only the base station in the NR system is taken as an example in the embodiment of the present application, but the specific type of the base station is not limited.

[0020] Hereinafter, technical terms related to the embodiments of the present application will be interpreted and described.

[0021] 1. Timing Advance Group (TAG) In Uu carrier aggregation (CA), there may be multiple TAGs, and the timing between different TAGs is different, while the timing of carriers or cells within the same TAG is the same. The same Timing Advance (TA) command is used to adjust the TA. FIG. 2 shows a schematic diagram of different TAGs.

[0022] 2. SL A terminal can communicate with other terminals on the sidelink, and these terminals may generally be vehicles, road site units (RSUs), mobile phones, etc. that support the sidelink technology.

[0023] The resource allocation mode of terminals supporting vehicle to everything (V2X) technology for information exchange between vehicles and the outside world may be divided into two types, generally referred to as mode 1 and mode 2. Here, mode 1: The base station can schedule or control the transmission of the terminal on the sidelink through the Uu interface and allocate corresponding resources for the terminal.

[0024] mode 2: The terminal itself obtains the resources for transmission on the sidelink by itself, and some terminals can further schedule the transmission of other terminals supporting V2X technology on the sidelink.

[0025] It should be noted that the above mode 1 and mode 2 may be represented using other names, and the embodiments of the present application are not limited thereto.

[0026] 3. NR SL Timing When the terminal performs sidelink transmission (e.g., transmission or reception), it transmits based on the timing of the selected synchronization reference source. Here, the synchronization source may also be referred to as a synchronization reference or a timing reference. The synchronization source of the terminal may be the base station, the global navigation satellite system (GNSS), the timing by the terminal's own local clock, or the timing by other devices. The sidelink resource may be numbered based on the sidelink timing. At this time, the frame number of the sidelink is directly referred to as the direct frame number (DFN), and the Sidelink channel includes the physical sidelink broadcast channel (PSBCH), the physical sidelink control channel (PSCCH), the physical sidelink shared channel (PSSCH), the physical sidelink feedback channel (PSFCH), etc.

[0027] 4. LTE SL Timing In LTE V2X, the time when the terminal transmits the sidelink radio frame number i is earlier than the first time length from the terminal's timing reference frame, and the first time length is (N TA,SL +N TAoffset) is · Ts seconds. If there is a cell that meets the S criterion in the cell corresponding to the terminal, at this time, the timing of the reference radio frame i is equal to the timing of the downlink radio frame i corresponding to this cell and the UL carrier for SL transmission. At this time, for frame structure type 1, N TAoffset = 0, and for frame structure type 2, N TAoffset = 624. If there is no cell that meets the S criterion in the cell corresponding to the terminal, N TAoffset = 0.

[0028] Here, for the PSSCH in the above mode 1, N TA,SL = N TA and N TA is the timing advance between the uplink timing and the downlink timing. For other cases, N TA,SL = 0. Figure 3 shows a schematic diagram of the SL timing relationship in this application.

[0029] 5. Configured uplink (UL) grant and configured sidelink grant For the demands of low-latency services or periodic services, in NR, configured UL grant supports two uplink transmission modes of uplink semi-static scheduling grants, namely type1 and type2. Here, the configured UL grant type1 resources may be semi-statically allocated by RRC signaling. After receiving this allocation, the terminal can transmit based on its own service arrival situation and the allocation situation, without the need for dynamic scheduling by downlink control information (DCI). The configured UL grant type2 resources may also be semi-statically allocated by RRC signaling. After receiving this allocation, the terminal cannot directly use it. Only after the base station further activates this allocation by DCI can the terminal use this grant resource based on this activated DCI. It should be noted that the base station can further deactivate this allocation by DCI, and the terminal receiving this DCI stops using this grant resource. Figure 4 shows an example of Configured UL grant type1, where one period includes four transmission occasions.

[0030] One configured UL grant generally corresponds to the resources that may be used for the periodic UE signal transmission, and multiple transmission occasions are included in each period. Compared with the general dynamic grant, configured UL grant can reduce the signaling overhead and interaction flow and ensure the low-latency requirements.

[0031] The concept of configured sidelink grant, which is similar to the configured UL grant in sidelink, is introduced. Generally, the configured sidelink grant can support the following two methods.

[0032] The control node does not need to allocate sidelink resources and send additional signaling to activate and / or deactivate this allocation. The terminal to which the resources are allocated can use these resources based on the incoming packet situation. This resource allocation may be referred to as configured sidelink grant type 1 and abbreviated as SL CG type 1.

[0033] The control node signaling needs to allocate sidelink resources and send additional signaling to activate and / or deactivate this allocation for this resource. This resource allocation may be referred to as configured sidelink grant type 2 and abbreviated as SL CG type 2.

[0034] It should be noted that the base station may allocate multiple configured sidelink grants.

[0035] One configured SL grant generally corresponds to resources that may be used for UE transmission periodically, and one or more transmission occasions are included in each period. Compared with the general dynamic grant, the above two methods can reduce the signaling overhead and interaction flow and ensure low latency requirements.

[0036] For SL CG type 1, the base station configures its period and the SL resource position within one period by means of RRC configuration. Then, the terminal can consider that the SL resource appears at the corresponding position periodically, and thereby determine the SL resources within one or more periods based on the configuration of SL CG type 1.

[0037] 6. Resources Scheduled by SL DCI SL DCI further indicates the interval K between the DCI and the first SL transmission scheduled by this DCI. SL The first SL transmission is not earlier than the first sidelink slot at the time of T DL -T TA / 2 + K SL ×T slot Here, T DL is the starting point for receiving the downlink slot where this DCI is located, T TA / 2 is the timing advance value, and T slot is the SL slot duration.

[0038] 7. SL HARQ Feedback To improve the reliability and resource utilization of data transmission on sidelink, a Hybrid Automatic Repeat reQuest (HARQ) feedback (i.e., sidelink HARQ-ACK) mechanism is supported in sidelink technology. After receiving sidelink data (the sidelink data is transmitted on the PSSCH. Here, the PSSCH is scheduled by the SCI, and the SCI is transmitted on the PSCCH and / or PSSCH), the sidelink receiving terminal can indicate whether the sidelink transmission is successful or failed by the feedback of sidelink HARQ-ACK information, and this sidelink HARQ-ACK is transmitted on the PSFCH resource. After receiving the sidelink HARQ-ACK information on the sidelink, the sidelink transmitting terminal can know whether the previous transmission is successful or failed. It should be noted that one sidelink terminal can receive or transmit sidelink data in different time or frequency domains respectively.

[0039] The transmission of sidelink data packets may be performed between the control node and the terminal (at this time the control node operates on the sidelink), and may also be performed on the sidelink between terminals. In such a case of the latter, the control node may not be able to directly know whether the transmission of this sidelink data packet is successful, and the terminal needs to transmit the sidelink HARQ-ACK information (for example, sidelink ACK / NACK) to the control node by the PUCCH or PUSCH, so that the control node can further determine whether the transmission on the sidelink is successful.

[0040] The terminal that transmits the sidelink HARQ-ACK information corresponding to a certain sidelink transmission to the base station is the transmitting terminal that transmits this sidelink transmission.

[0041] When the control node is a base station, the base station needs to allocate PUCCH or PUSCH resources for reporting sidelink HARQ-ACK information. The allocation of this PUCCH or PUSCH resource is realized by the PSFCH-PUCCH offset that indicates the slot interval between the PSFCH and the PUCCH in the RRC or DCI.

[0042] Specifically, the method for determining the PUCCH for reporting SL HARQ-ACK information by the PSFCH-PUCCH offset is as follows.

[0043] Assuming that the frame boundaries of the SL timing and the downlink (DL) timing are aligned, the terminal can infer one virtual last PSFCH position based on the DL timing of Uu. Then, the corresponding position after offsetting the PSFCH-PUCCH offset based on the virtual last PSFCH position is the position of the PUCCH.

[0044] As follows, the DL timing of the base station Uu and the SL timing are not aligned, and the DCI indicates K SL = 1 and indicates that the PSFCH-PUCCH offset = 2 slots. Then, the terminal performs SL transmission in the first sidelink slot that is not earlier than the time of T DL -T TA / 2 + K SL ×T slot in the resource pool, and can determine the PSFCH resource position related to this transmission. Then, based on the downlink timing, a virtual PSFCH slot aligned with this PSFCH slot boundary is determined. The position after offsetting the PSFCH-PUCCH offset = 2 slots based on this position is the position of the PUCCH.

[0045] Hereinafter, the information determination method according to the embodiments of the present application will be described in detail by specific embodiments and their application scenarios in conjunction with the drawings.

[0046] Regarding the information transmission method according to the embodiments of the present application, this information transmission method may be used in a terminal. In other words, this information transmission method may be executed by software or hardware installed in the terminal.

[0047] Based on this, as shown in FIG. 5, this information determination method may include the following step 201.

[0048] Step 201: Determine target information related to a target side link SL resource based on a target condition and / or a target reference object.

[0049] Here, the above target information is at least one of a first timing advance group TAG and first timing information, and at least one of the fact that the above target SL resource does not belong to any TAG and the fact that there is no timing information in the above target SL resource, and any one of the fact that there is no timing information in this first TAG and this target SL resource and the fact that this first timing information and this target SL resource do not belong to any TAG.

[0050] In the embodiments of the present application, the above target information may be arranged by a network side device for the terminal, may be determined by the terminal based on the state of this terminal, and may also be defined by a protocol. The embodiments of the present application are not limited thereto.

[0051] Optionally, in the embodiments of the present application, the above first timing information includes at least one of a first timing advance value and a downlink reference timing. Exemplarily, the first timing advance value is a first sub-timing advance value (for example, N TAis the timing advance between the uplink timing and the downlink timing), and a second sub-timing advance value (e.g., T TA may include at least one of the timing advance between the uplink timing and the downlink timing). Exemplarily, there may be a difference of one offset between the first sub-timing advance value and the second sub-timing advance value.

[0052] It should be noted that the downlink reference timing in this application may be used to determine the position of the feedback resource related to the SL transmission resource.

[0053] In the embodiments of this application, the above target conditions include at least one of the above target SL resource satisfying the first condition and the synchronization reference of the above terminal not being the base station or not being another terminal within the coverage of the base station. Here, this first condition includes at least one of being located in a non-shared resource, being located in an intelligent transport system (ITS) frequency band, being located in an SL dedicated resource, being located in a resource having only a PC5 interface, and being located in a resource that does not coexist with other technologies.

[0054] It should be noted that the above-mentioned being located in a non-shared resource may be understood as not being located in a shared resource. The above other technologies may include at least one of Uu technology, wifi technology, and frequency spectrum sharing technology.

[0055] It should be noted that the resource in this application may include at least one of a time-domain resource and a frequency-domain resource.

[0056] In the embodiments of the present application, the above target reference object may include one reference object or multiple reference objects, and the embodiments of the present application are not limited thereto.

[0057] In the embodiments of the present application, the above target reference object is at least one of a cell or carrier corresponding to a synchronization reference, a preset cell or preset carrier, a cell or carrier for transmitting first control signaling, a cell or carrier where a resource for transmitting SL feedback information is located, and a cell or carrier where the above target SL resource is located.

For example, taking the case where the synchronization reference of the terminal is GNSS as an example, if this terminal obtains (or searches) reliable GNSS on carrier 1, then the carrier corresponding to this synchronization reference is carrier 1.

[0060] In the second case, the above target reference object is a preset cell or preset carrier.

[0061] Example 1: The preset cell may be the cell with the largest cell identifier or the cell with the smallest cell identifier, and the preset carrier may be the carrier with the largest carrier identifier or the carrier with the smallest carrier identifier.

[0062] Example 2: The preset cell or preset carrier may be a cell or carrier corresponding to a preset identifier. For example, the preset cell or preset carrier may be a cell or carrier with a preset identifier of 0, or the preset cell or preset carrier may be a cell or carrier with a preset identifier of 1010.

[0063] Example 3: The preset cell or preset carrier may be located in a non - shared resource, or in the ITS band, or in an SL - dedicated resource, or in a resource having only the PC5 interface, or in a resource that does not coexist with other technologies.

[0064] Optionally, in the embodiments of the present application, this method may further include determining the target reference object as a preset reference object when the target SL resource meets the first condition.

[0065] Here, the preset reference object includes a preset cell or a preset carrier, the target information is information corresponding to the preset reference object, and the first condition includes at least one of being located in a non - shared resource, being located in the ITS band, being located in an SL - dedicated resource, being located in a resource having only the PC5 interface, and being located in a resource that does not coexist with other technologies.

[0066] In the third case, the target reference object is a cell or carrier that transmits the first control signaling.

[0067] Exemplarily, the first control signaling in the present application includes at least one of an SL semi - persistent scheduling (SPS) configuration, an SL CG configuration, and an SL DCI.

[0068] It should be noted that in this application, the SL DCI is the DCI for scheduling, activating, or deactivating SL resources. For example, the SL DCI may be the DCI scrambled by DCI format 3-0, or DCI format 3-1, or DCI format 5A, or SL-CS-RNTI, or SL-RNTI. The SL CG configuration in this application includes at least one of the SL CG type 1 configuration and the SL CG type 2 configuration.

[0069] Exemplarily, when the above target information includes the first TAG, this first TAG may be either the TAG corresponding to the cell or carrier that transmits the SL DCI or the TAG corresponding to the cell or carrier that transmits the SL CG configuration (for example, the SL CG type1 configuration).

For example, the second sub-timing advance value is the T corresponding to the cell or carrier that transmits the SL DCI TA or the T corresponding to the cell or carrier that transmits the SL CG type 1 configuration TA is.

[0071] In the fourth case, the above target reference object is the cell or carrier where the resource for transmitting the SL feedback information is located.

[0072] Exemplarily, the resource for transmitting the above-mentioned SL feedback information may be an uplink resource for transmitting the SL feedback information. For example, the SL feedback information may be SL HARQ-ACK, and the uplink resource for transmitting the SL feedback information may be PUCCH or PUSCH.

[0073] In the fifth case, the above-mentioned target reference object is the cell or carrier where the above-mentioned target SL resource is located.

[0074] It should be noted that the cell or carrier where the target SL resource is located in this application may be understood as the scheduled cell or carrier where the target SL resource is located, or the scheduled SL cell or SL carrier.

[0075] Exemplarily, when the above-mentioned target information includes a first TAG, this first TAG may be the TAG corresponding to the cell or carrier where the above-mentioned target SL resource scheduled or activated or deactivated by SL DCI is located, the TAG corresponding to the cell or carrier where the above-mentioned target SL resource arranged by the SL CG configuration (for example, SL CG type1 configuration) is located, or the TAG corresponding to the cell or carrier where the above-mentioned target SL resource arranged by the SL semi-static scheduling SPS configuration is located.

[0076] Exemplarily, when the target information includes first timing information, this first timing information may be any one of the timing information corresponding to the cell or carrier where the target SL resource scheduled, activated, or deactivated by the SL DCI is located, the timing information corresponding to the cell or carrier where the target SL resource arranged by the SL CG configuration (for example, SL CG type 1 configuration) is located, and the timing information corresponding to the cell or carrier where the target SL resource arranged by the SL semi-static scheduling SPS configuration is located.

[0077] It should be noted that the transmission in this application may be understood as transmission or reception. For example, the cell or carrier that transmits the first control signaling may be the cell or carrier where the base station transmits the first control signaling, or the cell or carrier where the terminal receives this first control signaling.

[0078] In the embodiments of this application, the above target SL resource may include one SL resource or multiple SL resources, and the embodiments of this application are not limited thereto. In the embodiments of this application, the above target SL resource may be at least one of an LTE SL resource and an NR SL resource. In the embodiments of this application, the above target SL resource may be an actual or candidate SL resource, and the embodiments of this application are not limited thereto. In the embodiments of this application, the above target SL resource may be indicated or arranged by the above first control signaling.

[0079] Optionally, in the embodiments of the present application, the target SL resource includes at least one of a first SL transmission resource that is indicated or arranged or scheduled or activated or deactivated by a first control signaling, and a first feedback resource corresponding to the first control signaling. Here, this first control signaling includes at least one of an SL SPS configuration, an SL CG configuration, and an SL DCI.

[0080] It should be noted that the above first SL transmission resource may be any one of all transmission resources that are indicated or arranged or scheduled or activated or deactivated by a first control signaling, and some transmission resources that are indicated or arranged or scheduled or activated or deactivated by a first control signaling. The above first feedback resource may be any one of a feedback resource corresponding to all SL transmission resources that are indicated or arranged or scheduled or activated or deactivated by a first control signaling, and a feedback resource corresponding to partial SL transmission resources that are indicated or arranged or scheduled or activated or deactivated by a first control signaling. For example, the first feedback resource may be the last PSFCH resource related to the PSSCH resource indicated by the first control signaling.

[0081] In one example, determining the timing information related to the target sidelink SL resource described above may be understood as determining the timing information related to the cell or carrier where the target SL resource is located.

[0082] Optionally, in the embodiments of the present application, the target reference object is at least one of a cell or carrier corresponding to a synchronization reference, a preset cell or a preset carrier, a cell or carrier transmitting first control signaling, a cell or carrier where a resource for transmitting SL feedback information is located, and a cell or carrier where the target SL resource is located. Here, the target information indicates the first TAG and / or the first timing information. Optionally, in the embodiments of the present application, the target SL resource can satisfy either one of the following: this target SL resource belongs to a specific TAG or does not belong to any specific TAG, and the first timing advance value corresponding to this target SL resource is 0 or there is no first timing advance value.

[0083] In one example, when the target condition includes that the target SL resource satisfies a first condition, the target information indicates that the target SL resource belongs to a predetermined TAG or does not belong to any TAG, and the first TAG is the predetermined TAG.

[0084] Here, the first condition includes at least one of being located in a non-shared resource, being located in the ITS band, being located in an SL dedicated resource, being located in a resource having only a PC5 interface, and being located in a resource that does not coexist with other technologies.

[0085] In another example, when the target condition includes at least one of the target SL resource satisfying a first condition and the synchronization reference of the terminal not being a base station or not being another terminal within the coverage of the base station, the target information indicates that there is no first timing advance value, or the target information is the first timing advance value, and the first timing advance value is 0.

[0086] Here, the first condition includes at least one of being located in a non-shared resource, being located in the ITS band, being located in an SL dedicated resource, being located in a resource having only the PC5 interface, and being located in a resource that does not coexist with other technologies.

[0087] Optionally, in the embodiments of the present application, when the target information indicates the first TAG and / or the first timing information, the target information is information corresponding to the target reference object.

[0088] Here, the information corresponding to the target reference object may include at least one of a TAG corresponding to the target reference object and timing information corresponding to the target reference object.

[0089] In a first example, when the target information indicates the first TAG, the target information may be a TAG corresponding to the target reference object.

[0090] Example 1: When the target reference object is a cell or carrier for transmitting SL DCI, the TAG corresponding to the target SL resource may be a TAG corresponding to the cell or carrier for transmitting SL DCI. For example, if carrier 1 schedules SL resources on carrier 2 and carrier 1 belongs to TAG1, the TAG corresponding to the SL resource is TAG1.

[0091] Example 2: When the target reference object is a cell or carrier where the uplink resource for transmitting SL HARQ-ACK is located, the TAG corresponding to the target SL resource may be a TAG corresponding to the cell or carrier where the uplink resource for transmitting SL HARQ-ACK is located.

[0092] Example 3: When the target reference object is the cell or carrier where the target SL resource is located, the TAG corresponding to the target SL resource may be the TAG corresponding to the cell or carrier where the target SL resource is located. For example, if Carrier 1 schedules the SL resource on Carrier 2 and Carrier 2 belongs to TAG2, the TAG corresponding to the SL resource is TAG2.

[0093] In the second example, when the above target information is the first timing information, the above target information may be the timing information corresponding to the above target reference object.

[0094] Exemplarily, the timing information corresponding to this target reference object may be the timing advance value corresponding to the target reference object or the downlink reference timing corresponding to the target reference object.

[0095] In the third example, when the above target information indicates the first TAG and the first timing information, the above target information may be the TAG and timing information corresponding to the above target reference object.

[0096] Exemplarily, when the target reference object includes a plurality of reference objects, the terminal may determine the first TAG and the first timing information based on the same reference object, or may determine the first TAG and the first timing information respectively based on different reference objects. The embodiments of the present application are not limited thereto. For example, taking the target reference object being Reference Object 1 and Reference Object 2 as an example, the terminal may determine the first TAG based on the TAG of Reference Object 1 and determine the first timing information based on Reference Object 2.

[0097] Furthermore, optionally, in the embodiments of the present application, the above first timing information may be determined based on the above first TAG.

[0098] In one example, the above first timing information may be determined based on the timing information corresponding to the above first TAG. For example, the first timing information is the timing information corresponding to the first TAG.

[0099] Optionally, in an embodiment of the present application, after the terminal determines the target information related to the target SL resource, the terminal may use this target information for SL transmission.

[0100] Exemplarily, after the above step 201, this method may further include the following step 202.

[0101] Step 202: Determine the resource position of the target SL resource based on the above target information.

[0102] In one example, the terminal can determine the resource position of the target SL resource based on all or part of the information in the above target information.

[0103] Optionally, in an embodiment of the present application, the resource position of the target SL resource may be determined based on a first position after performing a target offset based on the target position.

[0104] Here, the above target position is determined based on the first control signaling, the above target offset is determined based on the above target information, and this first control signaling includes at least one of an SL SPS configuration, an SL CG configuration, and an SL DCI. In one possible implementation, the target offset may be the result of multiplying a first sub-timing advance value by a coefficient a (for example, 0.5), or the result of multiplying a second sub-timing advance value by a coefficient b (for example, 0.5).

[0105] Optionally, in the embodiments of the present application, when the target SL resource is an LTE SL resource, the target SL resource is not located on a resource earlier than the first position.

[0106] For example, when the target SL resource is an LTE SL resource, the target SL resource is at a time earlier than T DL -N TA / 2×Ts+(4+m)×10 -3 not located on a resource earlier than the time.

[0107] Here, in the implementation method, N TA is the N corresponding to the cell or carrier where the SL DCI is located, and in another implementation manner, N TA is the N corresponding to the cell or carrier where the target SL resource is located. TA is the N corresponding to the cell or carrier where the target SL resource is located. TA is the N corresponding to the cell or carrier where the target SL resource is located.

[0108] Optionally, in the embodiments of the present application, when the target SL resource includes a second SL transmission resource indicated by the SL DCI, this second SL transmission resource is located on a preset resource that is not earlier than the first position.

[0109] Furthermore, when the target SL resource includes a second SL transmission resource indicated by the SL DCI, this second SL transmission resource is located on a preset resource that is not earlier than the first position within the resource pool.

[0110] Here, the first position is determined based on the target information.

[0111] For example, if the second SL transmission resource described above is the first SL transmission resource among the SL transmission resources indicated by the SL DCI, this second SL transmission resource is on the first SL slot within the resource pool that is not earlier than T DL -T TA / 2+K SL ×T slot not located on a resource earlier than the time.

[0112] Optionally, in the embodiments of the present application, when the target SL resource includes a third SL transmission resource in the SL CG arrangement, this third SL transmission resource is located at a first position.

[0113] Here, the target position is determined based on the downlink timing and the SL CG arrangement.

[0114] For example, the third SL transmission resource is a target position determined based on the downlink timing and the SL CG arrangement, and is located at a position after advancing by T TA / 2.

[0115] Optionally, in the embodiments of the present application, when the target SL resource includes a second feedback resource related to a fourth SL transmission resource, this second feedback resource is located at a first position determined when the downlink reference timing and the SL timing are aligned.

[0116] Exemplarily, the downlink reference timing and the SL timing may all be aligned, or partially aligned. The embodiments of the present application are not limited thereto.

[0117] For example, assuming that the downlink timing and the SL timing frame boundary are aligned, the second feedback resource is located at a feedback resource position determined when the downlink reference timing and the SL timing are all aligned.

[0118] It should be noted that the above T TA is the timing advance amount of the uplink with respect to the downlink of the target reference object, or the timing advance amount of the uplink with respect to the downlink of the TAG corresponding to the target reference object. The above T TA is N TAIt may be replaced. That is, the first timing information is the first sub-timing advance value. For example, the above formula T DL -T TA / 2 + K SL ×T slot may be replaced with the formula T DL -N TA / 2 + K SL ×T slot It may also be replaced. As can be understood, N in this application TA may also be replaced with T TA as well.

[0119] It should be noted that the above T DL is the time to receive the first control signaling determined based on the timing information of the above target reference object (for example, downlink timing information), or the time to receive the first control signaling determined based on the timing information of the TAG corresponding to the above target reference object (for example, downlink timing information). The above downlink reference timing (used to determine the related feedback resource position) is the downlink frame timing determined based on the timing information of the above target reference object (for example, downlink timing information), or the downlink frame timing determined based on the timing information of the TAG corresponding to the above target reference object (for example, downlink timing information).

[0120] It should be noted that the target reference object corresponding to the above T TA , the target reference object corresponding to N TA , the target reference object corresponding to T DL , and the target reference object corresponding to the downlink reference timing may all be the same, partially the same, or all different. The embodiments of this application are not limited thereto. Example 1, T DLThe target reference object corresponding to and / or the target reference object corresponding to the downlink reference timing is any cell that transmits SL DCI, T TA The target reference object corresponding to is the cell where the target SL resource is located.

[0121] It should be noted that the above T TA The first TAG related to (or corresponding to) the target reference object corresponding to , and the first TAG related to (or corresponding to) the target reference object corresponding to , and the first TAG related to (or corresponding to) the target reference object corresponding to the downlink reference timing may all be the same, partially the same, or all different. The embodiments of this application are not limited thereto. DL It should be noted that the above N

[0122] 、T TA 、T TA 、T DL and the downlink reference timing are determined based on the timing information of the above target reference object, or may be determined based on the timing information corresponding to the TAG corresponding to the above target reference object.

[0123] Optionally, in the embodiments of this application, when the above terminal corresponds to a plurality of first reference objects, one of the first reference objects includes uplink resources for transmitting SL feedback information, one of the first reference objects is used to transmit first control signaling, at least one of the at least two first reference objects is used to transmit first control signaling. Here, the above first reference object is a cell or a carrier, and the above first control signaling includes at least one of SL SPS configuration, SL CG configuration, and SL DCI.

[0124] It should be noted that the above-mentioned terminal corresponding to a plurality of first reference objects may be understood as any one of the following: the terminal is arranged or pre-arranged or instructed or scheduled to support a plurality of SL cells, or the terminal is arranged or pre-arranged or instructed or scheduled to support a plurality of SL carriers, or the terminal is arranged or pre-arranged or instructed or scheduled to support a preset number of SL cells, or the terminal is arranged or pre-arranged or instructed or scheduled to support a preset number of SL carriers. That is, the terminal may be understood to perform or support SL CA.

[0125] In one example, the fact that one first reference object is used to transmit first control signaling can meet the requirement that one first reference object is used to transmit first control signaling when the first control signaling is SL DCI.

[0126] Furthermore, optionally, in the embodiments of the present application, the above-mentioned first reference object for transmitting the first control signaling is a first reference object corresponding to the synchronization reference of the terminal.

[0127] Optionally, in the embodiments of the present application, when one first reference object includes an uplink resource for transmitting SL feedback information, the above-mentioned target reference object is a cell or carrier including the uplink resource for transmitting SL feedback information, Or, when one first reference object is used to transmit first control signaling, the above-mentioned target reference object is a cell or carrier for transmitting this first control signaling, Or, When at least two first reference objects are used to transmit first control signaling, the target reference object is any one of the cell or carrier corresponding to the synchronization reference, the cell or carrier where the target SL resource is located, and the cell or carrier where the first control signaling corresponding to the target SL resource is located. Or, The target reference object is the cell or carrier corresponding to the synchronization reference.

[0128] Here, the first reference object is a cell or carrier, and the first control signaling includes at least one of an SL SPS configuration, an SL CG configuration, and an SL DCI.

[0129] It should be noted that in the case of SL CA, considering that it is necessary to unify the TAGs of different SL carriers and / or the timing considered for SL resources, otherwise, the difference in timing will bring relatively high complexity and resource utilization problems. Therefore, when one first reference object is used to transmit first control signaling, the target reference object is the cell or carrier for transmitting this first control signaling.

[0130] In the following, the determination process of target information and / or target SL resources will be exemplarily described by at least three examples.

[0131] It should be noted that in the case of SL CA, considering that it is necessary to unify the TAGs of different SL carriers and / or the timing considered for resources. Otherwise, since the difference in timing will bring relatively high complexity and resource utilization problems, when at least two first reference objects are used to transmit first control signaling, the target reference object is the cell or carrier corresponding to the synchronization reference.

[0132] For ease of understanding, the cell or carrier where the above first control signaling is located is the cell or carrier that transmits the first control signaling.

[0133] Example 1: When the SL resource on cell 1 is scheduled by the SL DCI on cell 3 and the SL resource on cell 2 is scheduled by the SL DCI on cell 4, if the terminal obtains a synchronization reference on cell 1, the SL resource and / or target information of cell 1 may be determined based on cell 1, and / or the SL resource and / or target information of cell 2 may be determined based on cell 1. For example, the SL resource and / or TAG of cell 1 are determined according to cell 1, and / or the SL resource and / or TAG of cell 2 are determined according to cell 1.

[0134] Exemplarily, when at least two first reference objects are used to transmit the first control signaling, the target reference object is the cell or carrier where the SL resource is located.

[0135] Example 2: If the SL resource on cell 1 is scheduled by the SL DCI on cell 3 and the SL resource on cell 2 is scheduled by the SL DCI on cell 4, the SL resource and / or target information of cell 1 may be determined based on cell 1, and / or the SL resource and / or target information of cell 2 may be determined based on cell 2. For example, the SL resource and / or TAG of cell 1 are determined according to cell 1, and / or the SL resource and / or TAG of cell 2 are determined according to cell 2.

[0136] Exemplarily, when at least two first reference objects are used to transmit the first control signaling, the target reference object is the cell or carrier where the first control signaling corresponding to each SL resource is located.

[0137] Example 3: If SL carrier 1 is scheduled by the SL DCI on cell 3 and SL carrier 2 is scheduled by the SL DCI on cell 4, the SL resources and / or target information of SL carrier 1 may be determined based on cell 3, and / or the SL resources and / or target information of SL carrier 2 may be determined based on cell 4. For example, the SL resources and / or TAG of SL carrier 1 are determined according to cell 3, and / or the SL resources and / or TAG of SL carrier 2 are determined according to cell 4.
