The following description describes a New Radio (NR) system for illustrative purposes and uses NR terminology in most of the description below, however, these techniques may be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

[0019] FIG. 1 shows a block diagram of a wireless communication system to which the embodiment of the present application can be applied. The wireless communication system includes a terminal 11 and a network side device 12. Here, the terminal 11 may be called 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 (also 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 (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), etc., and the wearable device includes a bracelet, an earphone, 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 equipment 12 may be a base station or a core network. Here, the base station may be called 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 any other suitable term in the art, and the base station is not limited to a specific technical term as long as the same technical effect is achieved. It should be noted that the embodiment of this application only takes a base station in an NR system as an example, but does not limit the specific type of the base station.

[0020] In the following, technical terms related to the embodiments of the present application will be interpreted and explained.

[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 in the same TAG is the same. The same Timing Advance (TA) command is used to adjust the TA. Figure 2 shows a schematic diagram of different TAGs.

[0022] 2. SL A terminal can communicate with other terminals over the sidelink, which may typically be cars, road site units (RSUs), mobile phones, etc. that support sidelink technology.

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

[0024] Mode 2: The terminal obtains resources for its own transmission on the sidelink, and some terminals can also schedule transmissions on the sidelink of terminals that support other V2X technologies.

[0025] It should be clarified 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 a terminal performs sidelink transmission (e.g., transmission or reception), the terminal transmits based on the timing of a selected synchronization reference source. Here, the synchronization source may be referred to as a synchronization reference or a timing reference. The synchronization source of the terminal may be a base station, a global navigation satellite system (GNSS), timing by a terminal's own local clock, or timing by other devices. Sidelink resources may be numbered based on sidelink timing. In this case, the sidelink frame number is referred to as a direct frame number (DFN), and the sidelink channels include a physical sidelink broadcast channel (PSBCH), a physical sidelink control channel (PSCCH), a physical sidelink shared channel (PSSCH), a physical sidelink feedback channel (PSFCH), etc.

[0027] 4. LTE SL timing In LTE V2X, the time at which the terminal transmits a sidelink radio frame number i is a first time length earlier than a timing reference frame of the terminal, and the first time length is (N TA,SL +N TAoffset)·Ts seconds. If there is a cell corresponding to the terminal that satisfies the S criteria, then 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. Then, for frame structure type 1, N TAoffset = 0, and for frame structure type 2, N TAoffset = 624. If there is no cell corresponding to the terminal that satisfies the S criterion, N TAoffset =0.

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

[0029] 5. Configured uplink (UL) grant and configured sidelink grant For the needs of low latency or periodic services, the configured UL grant in NR supports two uplink transmission modes of uplink semi-static scheduling grant, namely type 1 and type 2. Here, the configured UL grant type 1 resource may be configured semi-statically by RRC signaling, and the terminal can transmit based on the terminal's own business arrival status and configuration status after receiving this configuration, and downlink control information (DCI) does not need to be dynamically scheduled. The configured UL grant type 2 resource may be configured semi-statically by RRC signaling, and the terminal cannot directly use this configuration after receiving it, and the terminal can use this grant resource based on the activation DCI only after the base station further activates this configuration by DCI. It should be noted that the base station can further deactivate this configuration by DCI, and the terminal receiving this DCI stops using this grant resource. Figure 4 shows an example of configured UL grant type 1, where one period includes four transmission occasions.

[0030] A configured UL grant generally corresponds to resources that may be used for periodic UE signal transmissions, and each period includes multiple transmission occasions. Compared with a typical dynamic grant, a configured UL grant can reduce signaling overhead and interaction flow and ensure low latency requirements.

[0031] The concept of configured sidelink grant, which is similar to the configured UL grant, has been introduced to sidelink, and the configured sidelink grant can generally support the following two methods.

[0032] The control node does not need to configure sidelink resources and send additional signaling to activate and / or deactivate the configuration, and the configured terminal can use these resources based on the incoming packet situation. This resource configuration may be called configured sidelink grant type 1, and is abbreviated as SL CG type 1.

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

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

[0035] A configured SL grant generally corresponds to a resource that may be used for UE transmission, which is periodic, and each period includes one or more transmission occasions. Compared with general dynamic scheduling (dynamic grant), the above two schemes can reduce signaling overhead and interaction flow and ensure low latency requirements.

[0036] For SL CG type 1, the base station configures the period and the SL resource position within one period according to RRC configuration, and the terminal then considers that the SL resource appears on the corresponding position periodically, and can thereby determine the SL resource within one or more periods according to the configuration of SL CG type 1.

[0037] 6. Resources scheduled by SL DCI The SL DCI further defines an interval K between the DCI and the first SL transmission scheduled by this DCI. SL The first SL transmission is performed by using the T DL -T TA / 2+K SL ×T slot Not earlier than the first sidelink slot of the time. DL is the starting point for receiving the downlink slot in which this DCI is located, and T TA / 2 is the timing advance value, T slot is the SL slot duration.

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

[0039] The transmission of the sidelink data packet may be between the control node and the terminal (the control node operates in the sidelink) or between the terminals on the sidelink. In the latter case, the control node may not directly know whether the transmission of the sidelink data packet is successful, and the terminal needs to transmit sidelink HARQ-ACK information (e.g., sidelink ACK / NACK) to the control node via PUCCH or PUSCH, so that the control node can further determine whether the transmission on the sidelink is successful.

[0040] A terminal that transmits sidelink HARQ-ACK information corresponding to a certain sidelink transmission to a base station is a 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. This PUCCH or PUSCH resource allocation is realized by a PSFCH-PUCCH offset, which indicates the slot interval between PSFCH and PUCCH in RRC or DCI.

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

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

[0044] As shown below, the DL timing and SL timing of base station Uu are not aligned, and the DCI is K SL = 1 and PSFCH-PUCCH offset = 2 slots, and then the terminal DL -T TA / 2+K SL ×T slot An SL transmission is performed in the first sidelink slot that is not earlier than the time, and a PSFCH resource position associated with this transmission can be determined. Then, a virtual PSFCH slot that is aligned with this PSFCH slot boundary is determined based on the downlink timing, and the position after offsetting PSFCH-PUCCH offset=2 slots based on this position is the position of the PUCCH.

[0045] The following describes in detail the information determining method according to the embodiments of the present application through specific embodiments and application scenarios in conjunction with the drawings.

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

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

[0048] Step 201: Based on a target condition and / or a target reference object, target information related to a target sidelink SL resource is determined.

[0049] Here, the target information indicates at least one of a first timing advance group TAG and first timing information, at least one of the target SL resource not belonging to any TAG and no timing information being present in the target SL resource, and any one of the first TAG and no timing information being present in the target SL resource, and the first timing information and the target SL resource not belonging to any TAG.

[0050] In the embodiment of the present application, the above target information may be configured by the network side device for the terminal, may be determined by the terminal based on the state of the terminal, and may be specified by the protocol, but the embodiment of the present application is not limited thereto.

[0051] Optionally, in the embodiment of the present application, the above-mentioned first timing information includes at least one of a first timing advance value and a downlink reference timing. Illustratively, the first timing advance value is a first sub-timing advance value (e.g., N TAis the timing advance between the uplink timing and the downlink timing), and a second sub-timing advance value (e.g., T TA is a timing advance between the uplink timing and the downlink timing. Illustratively, there may be an offset difference 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 relative to the SL transmission resource.

[0053] In an embodiment of the present application, the target conditions include at least one of the following: the target SL resource satisfies a first condition; and the synchronization reference of the terminal is not a base station or is not another terminal in the coverage of the base station, where the first condition includes at least one of the following: located in a non-shared resource, located in an intelligent transport system (ITS) frequency band, located in a resource dedicated to SL, located in a resource with only a PC5 interface, and located in a resource that does not coexist with other technologies.

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

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

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

[0057] In an embodiment 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 a first control signaling, a cell or carrier in which a resource for transmitting SL feedback information is located, and a cell or carrier in which the target SL resource is located.

[0058] In the first case, the target reference object is the cell or carrier corresponding to the synchronization reference.

[0059] It should be noted that the cell or carrier corresponding to the synchronization reference is any one of the cell or carrier from which the terminal obtains the synchronization reference, the cell or carrier from which the terminal obtains the synchronization source, and the cell or carrier from which the terminal obtains the synchronization timing. For example, take the synchronization reference of the terminal as an example that GNSS, if the terminal obtains (or searches) a reliable GNSS on carrier 1, the carrier corresponding to the synchronization reference is carrier 1.

[0060] In the second case, the target reference object is a pre-configured cell or a pre-configured carrier.

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

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

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

[0064] Optionally, in an embodiment of the present application, the method may further include: determining the target reference object as a pre-configured reference object when the target SL resource satisfies a first condition.

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

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

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

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

[0069] Exemplarily, when the target information includes a first TAG, the first TAG may be any one of a TAG corresponding to a cell or carrier transmitting an SL DCI and a TAG corresponding to a cell or carrier transmitting an SL CG configuration (e.g., an SL CG type 1 configuration).

[0070] Exemplarily, when the target information includes the first timing information, the first timing information may be any one of timing information corresponding to a cell or carrier transmitting an SL DCI and timing information corresponding to a cell or carrier transmitting an SL CG configuration (e.g., an SL CG type 1 configuration). For example, the second sub-timing advance value may be a T corresponding to a cell or carrier transmitting an SL DCI. TA or T corresponding to a cell or carrier transmitting the SL CG type 1 arrangement TA It is.

[0071] In the fourth case, the target reference object is a cell or carrier in which resources for transmitting SL feedback information are located.

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

[0073] In the fifth case, the target reference object is the cell or carrier in which the target SL resource is located.

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

[0075] Exemplarily, when the target information includes a first TAG, the first TAG may be any one of a TAG corresponding to a cell or carrier in which the target SL resource scheduled or activated or deactivated by SL DCI is located, a TAG corresponding to a cell or carrier in which the target SL resource configured by SL CG configuration (e.g., SL CG type 1 configuration) is located, and a TAG corresponding to a cell or carrier in which the target SL resource configured by SL semi-static scheduling SPS configuration is located.

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

[0077] It should be explained that transmission in this application may be understood as sending or receiving. For example, the above cell or carrier that transmits the first control signaling may be the cell or carrier from which the base station transmits the first control signaling, or the cell or carrier from which the terminal receives the first control signaling.

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

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

[0080] It should be explained that the above-mentioned first SL transmission resource may be any one of all transmission resources indicated or configured or scheduled or activated or deactivated by the first control signaling, and some transmission resources indicated or configured or scheduled or activated or deactivated by the first control signaling. The above-mentioned first feedback resource may be any one of feedback resources corresponding to all SL transmission resources indicated or configured or scheduled or activated or deactivated by the first control signaling, and feedback resources corresponding to partial SL transmission resources indicated or configured or scheduled or activated or deactivated by the 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 timing information related to the target sidelink SL resource as described above may be understood as determining timing information related to the cell or carrier in which the target SL resource is located.

[0082] Optionally, in the embodiment of the present application, the target reference object is at least one of a cell or carrier corresponding to a synchronization reference, a preconfigured cell or a preconfigured carrier, a cell or carrier transmitting a 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. Wherein, the target information indicates the first TAG and / or the first timing information. Optionally, in the embodiment of the present application, the target SL resource can satisfy any one of the following: the target SL resource belongs to a specific TAG or does not belong to any specific TAG; and the first timing advance value corresponding to the target SL resource is 0 or the first timing advance value does not exist.

[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 specified TAG or does not belong to any TAG, and the first TAG is the specified 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 a resource dedicated to SL, 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, if the target conditions include at least one of the target SL resource satisfying a first condition and the synchronization reference of the terminal being not a base station or not another terminal within the coverage of the base station, the target information indicates that the first timing advance value does not exist, 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 a resource dedicated to SL, being located in a resource having only a PC5 interface, and being located in a resource that does not coexist with other technologies.

[0087] Optionally, in an embodiment 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, the target information may be a TAG that corresponds to the target reference object, where the target information indicates a first TAG.

[0090] Example 1: when the target reference object is a cell or carrier that transmits SL DCI, the TAG corresponding to the target SL resource may be the TAG corresponding to the cell or carrier that transmits 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 above target reference object is a cell or carrier in which an uplink resource for transmitting a SL HARQ-ACK is located, the TAG corresponding to the target SL resource may be a TAG corresponding to a cell or carrier in which an uplink resource for transmitting a SL HARQ-ACK is located.

[0092] Example 3: when the above target reference object is a 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 an SL resource on carrier 2, and carrier 2 belongs to TAG2, the TAG corresponding to the SL resource is TAG2.

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

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

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

[0096] For example, when the target reference object includes multiple reference objects, the terminal may determine the first TAG and the first timing information according to the same reference object, or may determine the first TAG and the first timing information according to different reference objects, and the embodiment of the present application is not limited thereto. For example, taking the target reference object as a reference object 1 and a reference object 2, the terminal may determine the first TAG according to the TAG of the reference object 1, and determine the first timing information according to the reference object 2.

[0097] Further optionally, in an embodiment of the present application, the first timing information may be determined based on the first TAG.

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

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

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

[0101] Step 202: Determine a resource location of the target SL resource according to the target information.

[0102] In one example, the terminal may determine a resource location of the target SL resource based on all or part of the information in the target information.

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

[0104] Wherein, the target position is determined based on a first control signaling, and the target offset is determined based on the target information, the first control signaling including at least one of a SL SPS configuration, a SL CG configuration, and a SL DCI. In one possible implementation manner, the target offset may be a result of multiplying the first sub-timing advance value by a factor a (e.g., 0.5) or a result of multiplying the second sub-timing advance value by a factor b (e.g., 0.5).

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

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

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

[0108] Optionally, in an embodiment of the present application, when the target SL resource includes a second SL transmission resource indicated by the SL DCI, the second SL transmission resource is located on a pre-configured resource that is not earlier than the first location.

[0109] Furthermore, if the target SL resource includes a second SL transmission resource indicated by the SL DCI, the second SL transmission resource is located on a pre-configured resource not earlier than the first position in the resource pool.

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

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

[0112] Optionally, in an embodiment of the present application, when the target SL resource includes a third SL transmission resource in the SL CG configuration, the third SL transmission resource is located on the first position.

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

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

[0115] Optionally, in an embodiment of the present application, when the target SL resource includes a second feedback resource associated with a fourth SL transmission resource, the second feedback resource is located on a first position determined when the downlink reference timing and the SL timing are aligned.

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

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

[0118] As an explanation, the above T TA is the timing advance amount of the uplink on the target reference object relative to the downlink, or is the timing advance amount of the uplink of the TAG corresponding to the target reference object relative to the downlink. TA is N TAThat 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 Official T DL -N TA / 2+K SL ×T slot As can be understood, N in this application may be replaced by TA Also, T TA may be replaced with.

[0119] As an explanation, the above T DL is a time of receiving a first control signaling determined based on timing information (e.g., downlink timing information) of the target reference object, or is a time of receiving a first control signaling determined based on timing information (e.g., downlink timing information) of a TAG corresponding to the target reference object. The downlink reference timing (used to determine an associated feedback resource position) is a downlink frame timing determined based on timing information (e.g., downlink timing information) of the target reference object, or is a downlink frame timing determined based on timing information (e.g., downlink timing information) of a TAG corresponding to the target reference object.

[0120] As an explanation, the above T TA and the target reference object corresponding to N TA and the target reference object corresponding to T DL The target reference object corresponding to the downlink reference timing may be the same, may be partially the same, or may be different, and the embodiments of the present application are not limited thereto. DLThe target reference object corresponding to the downlink reference timing and / or the target reference object corresponding to the downlink reference timing are both cells transmitting SL DCI, and T TA The corresponding target reference object is the cell in which the target SL resource is located.

[0121] As an explanation, the above T TA A first TAG associated with (or corresponding to) a target reference object corresponding to T DL The first TAG associated with (or corresponding to) the target reference object corresponding to the downlink reference timing and the first TAG associated with (or corresponding to) the target reference object corresponding to the downlink reference timing may be all the same, may be partially the same, or may even be all different, and the embodiments of the present application are not limited thereto.

[0122] As an explanation, the above N TA , T TA , T DL The downlink reference timing may be determined based on timing information of the target reference object, or may be determined based on timing information corresponding to the TAG corresponding to the target reference object.

[0123] Optionally, in an embodiment of the present application, if the terminal supports multiple first reference objects, A first reference object includes an uplink resource for transmitting SL feedback information; a first reference object is used to transmit a first control signaling; and at least two first reference objects are used to transmit a first control signaling. Wherein, the first reference object is a cell or a carrier, and the first control signaling includes at least one of a SL SPS configuration, a SL CG configuration, and a SL DCI.

[0124] It should be explained 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 configured, or pre-configured, or indicated, or scheduled, or supports a plurality of SL cells, the terminal is configured, or pre-configured, or indicated, or scheduled, or supports a plurality of SL carriers, the terminal is configured, or pre-configured, or indicated, or scheduled, or supports a predetermined number of SL cells, or the terminal is configured, or pre-configured, or indicated, or scheduled, or supports a predetermined number of SL carriers. That is, the terminal may be understood as performing SL CA or supporting SL CA.

[0125] In one example, the one first reference object being used to transmit the first control signaling may satisfy that the one first reference object is used to transmit the first control signaling when the first control signaling is a SL DCI.

[0126] Further optionally, in an embodiment of the present application, the above first reference object for transmitting the first control signaling is a first reference object corresponding to a synchronization reference of the terminal.

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

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

[0129] It should be noted that in the case of SL CA, the timings considered for the TAGs and / or SL resources of different SL carriers need to be unified, otherwise the timing differences will lead to higher complexity and resource utilization problems, so when a first reference object is used to transmit a first control signaling, the target reference object is a cell or carrier for transmitting the first control signaling.

[0130] The following provides an illustrative description of the process of determining target information and / or target SL resources through at least three examples.

[0131] It should be mentioned that in the case of SL CA, the timings considered for TAGs and / or resources of different SL carriers need to be unified, otherwise the timing differences will bring about relatively high complexity and resource utilization problems, so when at least two first reference objects are used to transmit the first control signaling, the target reference object is a cell or carrier corresponding to the synchronization reference.

[0132] As can be understood, the cell or carrier in which the above-mentioned first control signaling is located is the cell or carrier that transmits the first control signaling.

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

[0134] Illustratively, when at least two first reference objects are used to transmit the first control signaling, the target reference objects are cells or carriers in which the SL resources are located respectively.

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

[0136] Illustratively, when at least two first reference objects are used to transmit the first control signaling, the target reference objects are cells or carriers in which the first control signaling corresponding to the SL resources respectively is located.

[0137] Example 3: if SL carrier 1 is scheduled by a SL DCI on cell 3 and SL carrier 2 is scheduled by a SL DCI on cell 4, then 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.

[0138] Optionally, in an embodiment of the present application, the method may further include the following step 203:

[0139] Step 203: Get the target timing advance command.

[0140] Here, the accuracy of the target timing advance command is related to either the SL subcarrier spacing (SCS), the UL SCS or the first SCS in the SL SCS.

[0141] Exemplarily, the target timing advance command includes at least one of a timing advance command corresponding to the target SL resource and a timing advance command corresponding to the first TAG.

[0142] Exemplarily, the SL SCS may include one SCS or multiple SCSs, and the embodiment of the present application is not limited thereto. The UL SCS may include one SCS or multiple SCSs, and the embodiment of the present application is not limited thereto. For example, if there are multiple active UL BWPs in one TAG, the timing advance command is said to or defined according to the SCSs of the multiple active UL BWPs and the maximum SCS in the SL SCS.

[0143] Exemplarily, the above target timing advance command may be a target timing advance command sent (or configured) by a network side device to a terminal, or may be a target timing advance command sent (or configured) by another terminal to the above terminal, and the embodiments of the present application are not limited thereto.

[0144] It should be noted that the target timing advance command precision may be understood to be an integer multiple of the time unit corresponding to the SCS. In one example, the target timing advance command precision is 16 64 Tc / 2 μ and dividing this SCS by 15kHz is 2 to the power of μ. Alternatively, the time unit is 16·64·Tc / 2 μ Alternatively, the accuracy of the target timing advance command may be interpreted with respect to a certain SCS, or the accuracy of the target timing advance command may be interpreted with respect to a time unit corresponding to a certain SCS.

[0145] Alternatively, in the embodiment of the present application, the network side equipment configuration ensures that the SL SCS is not greater than (i.e., less than or equal to) the Uu SCS, and further ensures that the SL SCS is not greater than the corresponding Uu SCS of the same TAG; or the network side equipment configuration ensures that the SL SCS is not less than (i.e., greater than or equal to) the Uu SCS, and further ensures that the SL SCS is not less than the corresponding Uu SCS of the same TAG.

[0146] Alternatively, in an embodiment of the present application, the terminal considers or desires that the SL SCS is not larger than the Uu SCS, and furthermore, the terminal considers or desires that the SL SCS is not larger than the corresponding Uu SCS of the same TAG, or the terminal considers or desires that the SL SCS is not smaller than the Uu SCS, and furthermore, the terminal considers or desires that the SL SCS is not smaller than the corresponding Uu SCS of the same TAG.

[0147] It should be noted that the above Uu SCS may be understood as an SCS of Uu interface transmission or resources, including a UL SCS and / or a DL SCS, and in one example, the above first SCS may be a UL SCS and may also be an SCS of a UL active BWP.

[0148] Optionally, in an embodiment of the present application, the accuracy of the target timing advance command is: When the target SL resource is located at a preset frequency domain position, the accuracy of the target timing advance command is relative to a SL SCS; If there are multiple SL SCSs, the accuracy of the target timing advance command satisfies any one of the following conditions: the accuracy of the target timing advance command is related to an SL SCS that satisfies the second condition among the multiple SL SCSs.

[0149] Exemplarily, the location of the above target SL resource at a pre-configured frequency domain location includes at least one of: being located in a non-shared resource, being located in an ITS band, being located in a resource dedicated to SL, being located in a resource having only a PC5 interface, and being located in a resource that does not coexist with other technologies.

[0150] For example, the SL SCS that satisfies the above second condition includes any one of the maximum SL SCS, the minimum SL SCS, the SL SCS of a pre-configured carrier or a pre-configured cell, and the SL SCS with the largest number of corresponding carriers or cells.

[0151] Alternatively, in the embodiment of the present application, the UL SCS and the SL SCS may correspond to the same TAG or different TAGs, and the embodiment of the present application is not limited thereto.

[0152] It should be explained that when the precision of the target timing advance command is the precision of the timing advance command corresponding to the target SL resource, the precision of the timing advance command corresponding to the UL BWP under the first TAG and the precision of the timing advance command corresponding to the target SL resource may be the same or different, and the embodiment of the present application is not limited thereto.When the precision of the target timing advance command is the precision of the timing advance command corresponding to the first TAG, the precision of the timing advance command corresponding to the UL BWP and SL BWP under the first TAG and the precision of the timing advance command corresponding to the first TAG may be the same.

[0153] Optionally, in the embodiment of the present application, when the target timing advance command is a timing advance command corresponding to the first TAG, the first SCS may be a preset SCS in the UL SCS and the SL SCS in the first TAG. Exemplarily, the first SCS may be a maximum SCS or a minimum SCS in the UL SCS and the SL SCS in the first TAG, and the embodiment of the present application is not limited thereto.

[0154] Furthermore, the first SCS may be a preset SCS among the SCS of the active UL BWP and the SL SCS in the first TAG. Exemplarily, the first SCS may be a maximum SCS or a minimum SCS among the SCS of the active UL BWP and the SL SCS.

[0155] Example 1: A SL BWP belongs to TAG2, and the maximum SCS of all active UL BWPs in TAG2 is 30kHz, and the SL BWP is 60kHz, then the accuracy of the timing advance command corresponding to UL and SL of this TAG2 is 60kHz.

[0156] Example 2: An SL BWP belongs to TAG2, and if the maximum SCS of all active UL BWPs in TAG2 is 30kHz and the SL BWP is 60kHz, then the accuracy of the timing advance command corresponding to the UL of this TAG2 is 30kHz, and the accuracy of the timing advance command corresponding to the SL of this TAG2 is 60kHz.

[0157] The following will exemplarily explain the process of determining target information through at least four examples.

[0158] Example 1: The target SL resource is an SL resource scheduled by an SL DCI, the SL DCI indicates an interval between the DCI and the first SL transmission scheduled by this DCI, and the start of the first SL transmission is T DL -T TA / 2+K SL ×T slot Not earlier than the first sidelink slot of the time. DL is the starting point for receiving the downlink slot in which this DCI is located, and T TA is the timing advance amount of the cell in which the target SL resource is located.

[0159] Example 2: The target SL resource is an SL resource scheduled by an SL DCI, the SL DCI indicates an interval between the DCI and the first SL transmission scheduled by this DCI, and the start of the first SL transmission is T DL -T TA / 2+K SL ×T slotNot earlier than the first sidelink slot of the time. DL is the starting point for receiving the downlink slot in which this DCI is located, and T TA is the timing advance amount of the cell in which the SL HARQ-ACK is located.

[0160] Example 3: The target SL resource is an SL resource scheduled by an SL DCI, the SL DCI indicates an interval between a DCI and a first SL transmission scheduled by the DCI, and the start of the first SL transmission is a T DL -T TA / 2+K SL ×T slot Not earlier than the first sidelink slot of the time. DL is the starting point for receiving the downlink slot in which this DCI is located, and T TA is the timing advance amount of the cell in which the SL DCI is located.

[0161] Example 4: If SL CG type 1 is configured in the terminal, or if SL CG type 1 is configured in the terminal and SL CG type 2 and SL DCI are not configured in the terminal, or if SL CG type 1 is configured in the terminal and SL DCI is not configured in the terminal, the target SL resource corresponding to SL CG type 1 needs to be considered. TA is the cell that transmits the SL CG type 1 configuration or the cell in which this target SL resource is located.

[0162] Regarding the information determination method according to the embodiment of the present application, the information determination device determines target information related to a target sidelink SL resource based on a target condition and / or a target reference object, where the target information indicates at least one of a first timing advance group TAG and a first timing information, at least one of the following: the target SL resource does not belong to any TAG and there is no timing information for the target SL resource, the first TAG and the target SL resource do not have timing information, and the first timing information and the target SL resource do not belong to any TAG. In this way, the information determination device can quickly determine the required information based on the target condition and / or the target reference object, for example, determine the required TAG in multiple TAGs.

[0163] Regarding the information transmission method according to the embodiment of the present application, the information transmission method may be used in a communication device. In other words, the information transmission method may be executed by software or hardware installed in the communication device. The communication device may be a network side device or a terminal, etc.

[0164] Based on this, as shown in FIG. 6, the information transmission method may include the following step 301.

[0165] Step 301: Send a target timing advance command to a terminal.

[0166] Here, the accuracy of the target timing advance command is related to one of the SL carrier spacing SCS, the UL SCS and the first SCS in the SL SCS.

[0167] In response, the terminal may receive a target timing advance command transmitted by the communication device.

In one example, the target timing advance command precision is 16 64 Tc / 2 μ and dividing this SCS by 15kHz is 2 to the power of μ. Alternatively, the time unit is 16·64·Tc / 2 μ Alternatively, the accuracy of the target timing advance command may be interpreted with respect to a certain SCS, or the accuracy of the target timing advance command may be interpreted with respect to a time unit corresponding to a certain SCS.

[0171] Optionally, in the embodiment of the present application, the network side equipment configuration ensures that the SL SCS is not larger than the Uu SCS, and further ensures that the SL SCS is not larger than the corresponding Uu SCS of the same TAG; or the network side equipment configuration ensures that the SL SCS is not smaller than the Uu SCS, and further ensures that the SL SCS is not smaller than the corresponding Uu SCS of the same TAG.

[0176] For example, the SL SCS that satisfies the above second condition includes any one of the maximum SL SCS, the minimum SL SCS, the SL SCS of a pre-configured carrier or a pre-configured cell, and the SL SCS with the largest number of corresponding carriers or cells.

[0177] Alternatively, in the embodiment of the present application, the UL SCS and the SL SCS may correspond to the same TAG or different TAGs, and the embodiment of the present application is not limited thereto.

[0178] It should be explained that when the precision of the target timing advance command is the precision of the timing advance command corresponding to the target SL resource, the precision of the timing advance command corresponding to the UL BWP under the first TAG and the precision of the timing advance command corresponding to the target SL resource may be the same or different, and the embodiment of the present application is not limited thereto.When the precision of the target timing advance command is the precision of the timing advance command corresponding to the first TAG, the precision of the timing advance command corresponding to the UL BWP and SL BWP under the first TAG and the precision of the timing advance command corresponding to the first TAG may be the same.

[0179] Optionally, in the embodiment of the present application, when the target timing advance command is a timing advance command corresponding to the first TAG, the first SCS may be a preset SCS in the UL SCS and the SL SCS in the first TAG. Exemplarily, the first SCS may be a maximum SCS or a minimum SCS in the UL SCS and the SL SCS in the first TAG, and the embodiment of the present application is not limited thereto.

[0180] Furthermore, the first SCS may be a preset SCS among the SCS of the active UL BWP and the SL SCS in the first TAG. Exemplarily, the first SCS may be a maximum SCS or a minimum SCS among the SCS of the active UL BWP and the SL SCS.

[0181] Example 1: A SL BWP belongs to TAG2, and the maximum SCS of all active UL BWPs in TAG2 is 30kHz, and the SL BWP is 60kHz, then the accuracy of the timing advance command corresponding to UL and SL of this TAG2 is 60kHz.

[0182] Example 2: An SL BWP belongs to TAG2, and if the maximum SCS of all active UL BWPs in TAG2 is 30kHz and the SL BWP is 60kHz, then the accuracy of the timing advance command corresponding to the UL of this TAG2 is 30kHz, and the accuracy of the timing advance command corresponding to the SL of this TAG2 is 60kHz.

[0183] In the information transmitting method according to the embodiment of the present application, the information transmitting device can send a target timing advance command to the terminal, so that the terminal can quickly adjust the timing advance value according to the target timing advance command.
