However, when side transmission is required, how the terminal device accurately determines the time domain resources of SL CG is a technical problem that needs to be solved urgently. Summary of the invention

[0044] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0045] It should be understood that the "indication" mentioned in the embodiments of the present application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association relationship between A and B.

[0046] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between two items, or an association relationship between the two items, or a relationship between indication and being indicated, configuration and being configured, and the like.

[0047] It should be noted that, in the sideline communication, according to the network coverage of the communicating terminal, it can be divided into the sideline communication within the network coverage, such as Figure 1 As shown; some networks cover sideline communications, such as Figure 2 As shown; and network coverage outside the line communication, such as Figure 3 shown.

[0048] Figure 1 : In the sideline communication within the network coverage, all the terminals performing the sideline communication are within the coverage of the same base station. Thus, the above terminals can perform the sideline communication based on the same sideline configuration by receiving the configuration signaling of the base station.

[0049] Figure 2 : In the case of partial network coverage for sidelink communication, some terminals performing sidelink communication are located within the coverage of the base station. These terminals can receive the configuration signaling of the base station and perform sidelink communication according to the configuration of the base station. However, terminals outside the network coverage cannot receive the configuration signaling of the base station. In this case, the terminals outside the network coverage will determine the sidelink configuration and perform sidelink communication based on the pre-configuration information and the information carried in the Physical Sidelink Broadcast Channel (PSBCH) sent by the terminals within the network coverage.

[0050] Figure 3 : For sideline communications outside the network coverage, all terminals performing sideline communications are located outside the network coverage, and all terminals determine the sideline configuration according to pre-configuration information to perform sideline communications.

[0051] It should be noted that device-to-device communication is a sidelink (SL) transmission technology based on terminal-to-terminal (Device to Device, D2D), which is different from the way in which communication data is received or sent by base stations in traditional cellular systems, so it has higher spectrum efficiency and lower transmission delay. The Internet of Vehicles system adopts terminal-to-terminal direct communication, and 3GPP defines two transmission modes, which are respectively recorded as: Mode A and Mode B. The embodiments of the present application can be applied to Mode A and / or Mode B.

[0052] Mode A: The transmission resources of the terminal are allocated by the base station, and the terminal sends data on the sidelink according to the resources allocated by the base station; the base station can allocate resources for a single transmission to the terminal, or allocate resources for semi-static transmission to the terminal. Figure 1 As shown, the terminal is within the coverage of the network, and the network allocates transmission resources for sideline transmission to the terminal.

[0053] Mode B: The terminal selects a resource in the resource pool to transmit data. Figure 3As shown, the terminal is located outside the cell coverage, and the terminal autonomously selects transmission resources from the pre-configured resource pool for side transmission; or, as shown Figure 1 As shown, the terminal autonomously selects transmission resources from the resource pool configured by the network for side transmission.

[0054] It should be noted that in NR-V2X, the user may be in a mixed mode, that is, the user can use mode A to acquire resources and mode B to acquire resources at the same time.

[0055] In NR-V2X, autonomous driving is supported, which puts higher requirements on data interaction between vehicles, such as higher throughput, lower latency, higher reliability, larger coverage, more flexible resource allocation, etc.

[0056] In LTE-V2X, broadcast transmission is supported, and in NR-V2X, unicast and multicast transmission are introduced. For unicast transmission, there is only one receiving terminal, such as Figure 4 As shown in FIG, UE1 and UE2 perform unicast transmission; for multicast transmission, the receiving end is all terminals in a communication group, or all terminals within a certain transmission distance, such as Figure 5 As shown, UE1, UE2, UE3 and UE4 form a communication group, in which UE1 sends data, and other terminal devices in the group are receiving terminals; for the broadcast transmission mode, the receiving end is any terminal around the sending terminal, such as Figure 6 As shown, UE1 is a transmitting terminal, and other terminals around it, UE2-UE6 are all receiving terminals.

[0057] A resource pool is introduced in the sideline transmission system. The so-called resource pool is a collection of transmission resources. Whether it is a transmission resource configured by the network or a transmission resource selected by the terminal independently, it is a resource in the resource pool. The resource pool can be configured by pre-configuration or network configuration, and one or more resource pools can be configured. The resource pool is divided into a sending resource pool and a receiving resource pool. The sending resource pool is the transmission resources in the resource pool used to send sideline data; the receiving resource pool is the transmission resources in the resource pool where the terminal receives sideline data.

[0058] In LTE-V2X, the subframe set for mode 3 (i.e., mode A above) or mode 4 (i.e., mode B above) sidelink transmission in the physical sidelink shared channel (PSSCH) resource pool can be expressed as in, The subframe index is relative to subframe #0 of the radio frame of SFN0 or DFN0 of the serving cell.

[0059] The subframe set includes all subframes except the following subframes:

[0060] A subframe configured with a sidelink synchronization signal (SLSS) resource;

[0061] Downlink subframes and special subframes in TDD systems;

[0062] · Reserved subframes.

[0063] The terminal device determines the set of subframes allocated to the PSSCH resource pool as follows:

[0064] The terminal device uses the bitmap Determine the time domain resources of the PSSCH resource pool;

[0065] If b k' =1, subframe Belongs to the resource pool. Among them, k'=kmodL bitmap , the length of the bitmap is L bitmap Configured by high level.

[0066] In LTE-V2X, the resource pool is determined within a system frame number (SFN) or direct frame number (DFN) period. An SFN period includes 10240 subframes, corresponding to subframes 0, 1, 2, ..., 10239 (also called physical time slots or physical subframes). Excluding synchronization subframes, downlink subframes, special subframes (i.e., downlink subframes and special subframes in TDD systems), and reserved subframes, the remaining subframes are numbered as follows: The number of remaining subframes can be L bitmap Divisibility, bitmap It is repeated periodically in the remaining subframes, and a bit being 1 indicates that the subframe corresponding to the bit in the remaining subframes belongs to the resource pool, otherwise it does not belong to the resource pool.

[0067] like Figure 7As shown, one SFN cycle (or DFN cycle) includes 10240 subframes, the period of the synchronization signal is 160ms, and two synchronization subframes are included in one synchronization cycle. Therefore, there are 128 synchronization subframes in one SFN cycle. The length of the bitmap used to indicate the time domain resources of the resource pool is 10 bits, so two reserved subframes are required. The number of remaining subframes is (10240-128-2=10110), which can be divided by the length of the bitmap 10. The remaining subframes are renumbered as 0, 1, 2, ..., 10109 (also called logical time slots or logical subframes). The first 3 bits of the bitmap are 1, and the remaining 7 bits are 0, that is, in the remaining subframes, the first 3 subframes in every 10 subframes belong to the resource pool, and the remaining subframes do not belong to the resource pool. Since the bitmap needs to be repeated 1011 times in the remaining subframes to indicate whether all subframes belong to the resource pool, and each bitmap period includes 3 subframes, a total of 3033 subframes belong to the resource pool in one SFN period.

[0068] In NR-V2X, resource allocation methods of Mode 1 and Mode 2 are supported. In Mode 2, the terminal autonomously selects transmission resources from the resource pool for sidelink transmission, which is the above-mentioned Mode B; in Mode 1, the network allocates sidelink transmission resources to the terminal, which is the above-mentioned Mode A. Specifically, the network device can allocate sidelink transmission resources to the terminal through dynamic scheduling (Dynamic Scheduling, DG); or the network can allocate sidelink configuration grant (SL CG) transmission resources to the terminal, or called sidelink unauthorized transmission resources. SL CG mainly includes two configuration authorization methods: the first type of sidelink configuration authorization (type-1Sidelink configured grant, type-1SL CG) and the second type of configuration authorization (type-2 Sidelink configured grant, type-2SL CG).

[0069] The first type of sideline configuration authorization: The network device configures the sideline transmission resources for the terminal through the Radio Resource Control (RRC) signaling. The RRC signaling configuration includes all transmission resources and transmission parameters including time domain resources, frequency domain resources, demodulation reference signal (DMRS), modulation and coding scheme (MCS), etc. When the terminal device receives the high-level parameters, it can immediately use the configured transmission parameters to perform sideline transmission on the configured time-frequency resources.

[0070] The second type of sideline configuration authorization: adopts a two-step resource configuration method, namely the RRC+DCI method; first, the RRC signaling configures the transmission resources and transmission parameters including the period of time-frequency resources, redundant version, number of retransmissions, number of hybrid automatic repeat request (HARQ) processes, etc., and then the DCI activates the transmission of the second type of configuration authorization, and simultaneously configures other transmission resources and transmission parameters including time domain resources, frequency domain resources, MCS, etc. When the terminal device receives the RRC signaling, it cannot immediately use the resources and parameters configured by the high-level parameters for sideline transmission, but must wait until it receives the corresponding downlink control information (Downlink Control Information, DCI) that activates the sideline configuration authorization before it can perform sideline transmission. In addition, the network can deactivate the sideline configuration authorization through DCI. When the terminal receives the deactivated DCI, it can no longer use the sideline configuration authorization transmission resources for sideline transmission.

[0071] For the first type of sideline configuration grant (type-1SL CG), the corresponding time domain resource is determined by the following formula 1:

[0072] [(SFN×numberOfSLSlotsPerFrame)+logical slot number in the frame]=(timeReferenceSFN×numberOfSLSlotsPerFrame+sl-TimeOffsetCGType1+S×PeriodicitySL)modulo(1024×numberOfSLSlotsPerFrame) Formula 1

[0073] In formula 1, N represents the number of logical time slots that can be used for sideline transmission in a time range of 20ms, sl_periodCG represents the period of SL CG configured by the network; numberOfSLSlotsPerFrame represents the number of logical time slots that can be used for sideline transmission in a wireless frame; logical slot number in the frame represents the number of logical time slots in the wireless frame; timeReferenceSFN represents the time reference SFN; sl-TimeOffsetCGType1 represents the time domain offset of type-1CG; S represents any integer.

[0074] For the second type of sideline configuration grant (type-2SL CG), the corresponding time domain resources are determined by the following formula 2:

[0075] [(SFN×numberOfSLSlotsPerFrame)+logical slot number in the frame]=

[0076] [(SFN start time ×numberOfSLSlotsPerFrame+slot start time )+S×PeriodicitySL]modulo(1024×numberOfSLSlotsPerFrame) formula 2

[0077] In formula 2, N represents the number of logical time slots that can be used for sideline transmission in a 20ms time range, sl_periodCG represents the period of SL CG configured by the network; numberOfSLSlotsPerFrame represents the number of logical time slots that can be used for sideline transmission in a radio frame; logical slot number in the frame represents the number of logical time slots in a radio frame; SFN start time Indicates the SFN corresponding to the first PSSCH transmission opportunity in the CG resource; slot start time It represents the logical time slot corresponding to the first PSSCH transmission opportunity in the CG resource; sl-TimeOffsetCGType1 represents the time domain offset of type-1CG; S represents any integer.

[0078] However, there are the following three problems in the above formula 1 and formula 2:

[0079] Question 1: In Formula 1 and Formula 2, The parameter PeriodicitySL obtained by this formula includes all logical time slots that can be used for sideline transmission (for example, corresponding to Figure 7 ), and SL CG is configured in a resource pool (for example, corresponding to Figure 7 The third row in the figure), and the length of the bitmap used to indicate the resource pool time slot is any value in [10,100], which may not be an integer multiple of the number of time slots included in the 20ms time range. Therefore, the time slot determined by Formula 1 and Formula 2 above may not belong to the resource pool associated with the SL CG, and therefore does not belong to the time domain transmission resource authorized by the side configuration.

[0080] Question 2: In the above formulas 1 and 2, numberOfSLSlotsPerFrame represents the number of logical time slots that can be used for side transmission in a wireless frame. However, the formula for determining the period is determined based on a period of 20ms. 20ms includes 2 wireless frames. The number of logical time slots that can be used for side transmission in each wireless frame may be different. For example, 20ms includes 10 logical time slots that can be used for side transmission, but the first 10ms (one wireless frame) includes 3 logical time slots, and the second 10ms (another wireless frame) includes 7 logical time slots. At this time, the value of numberOfSLSlotsPerFrame is different in different wireless frames. It is impossible to determine whether it is 3 or 7.

[0081] Question 3: For SL CG, in each CG cycle, the network device can configure up to 3 transmission resources. However, in the above formula for determining the authorized transmission resources for sideline configuration, only the first transmission resource in each cycle is considered, i.e., sl-TimeOffsetCGType1 in type-1 SL CG and SFN in type-2 SL CG. start time and slot start time , and does not consider the time domain position corresponding to the second or third transmission resource.

[0082] Based on the above problems, the present application proposes a solution for determining the sidelink configuration authorization resources, which can solve the above technical problems.

[0083] The technical solution of the present application is described in detail below through specific embodiments.

[0084] Figure 8 is a schematic flow chart of a method 200 for determining a sidelink configuration authorization resource according to an embodiment of the present application, such as Figure 8 As shown, the method 200 may include at least part of the following contents:

[0085] S210, the terminal device determines the time domain resources authorized by the first side configuration according to the first information, wherein:

[0086] The first information includes but is not limited to at least one of the following:

[0087] The period of the first sideline configuration authorization corresponds to the number of time slots in the resource pool associated with the first sideline configuration authorization, the average number of logical time slots used for sideline transmission in a wireless frame, SFN information within the time range of the dual SFN, logical time slot information within the time range of the dual SFN, time domain offset within the time range of the dual SFN, and the offset value in the time domain between the target sideline transmission resource in the first sideline configuration authorization and the first sideline transmission resource.

[0088] It should be noted that, in the embodiment of the present application, the time range of the dual SFN may be a time range of 20 ms.

[0089] Optionally, the first sidewalk configuration authorization may be a first type of sidewalk configuration authorization, wherein the first type of sidewalk configuration authorization is a sidewalk configuration authorization configured by the network device through RRC signaling. For details, please refer to the above description of the first type of sidewalk configuration authorization, which will not be repeated here for brevity.

[0090] Optionally, the first side configuration authorization may also be a second type of side configuration authorization, wherein the second type of side configuration authorization is a side configuration authorization configured by the network device through RRC signaling and activated through DCI. For details, please refer to the above description of the second type of side configuration authorization, which will not be repeated here for the sake of brevity.

[0091] Optionally, as Example 1, the first information includes the number of time slots corresponding to the period of the first side row configuration authorization in the resource pool associated with the first side row configuration authorization. That is, the terminal device can determine the time domain resources authorized by the first side row configuration according to the number of time slots corresponding to the period of the first side row configuration authorization in the resource pool associated with the first side row configuration authorization.

[0092] Optionally, in Example 1, the number of time slots corresponding to the period of the first side configuration authorization in the resource pool associated with the first side configuration authorization is determined by at least one of the following information:

[0093] The total length of the bitmap used to configure the time domain resources of the resource pool, the number of first values ​​in the bitmap used to configure the time domain resources of the resource pool, and the period of the first side configuration authorization configured by the network device.

[0094] Optionally, the value of the resource pool associated with the first side configuration authorization in the bitmap is the first value.

[0095] For example, the first value is 1.

[0096] Optionally, in Example 1, the number of time slots corresponding to the period of the first side configuration authorization in the resource pool associated with the first side configuration authorization can be obtained by the following formula 3.

[0097]

[0098] Among them, N represents the number of logical time slots that can be used for side transmission in the time range of 20ms, sl_periodCG represents the period of the first side configuration authorization of the network configuration, k represents the number of values ​​1 in the bit map used to configure the time domain resources of the resource pool, and L represents the total length of the bit map used to configure the time domain resources of the resource pool.

[0099] Specifically, in Example 1, the terminal device can obtain PeriodicitySL based on Formula 3.

[0100] Further, in the case where the first side row configuration authorization is a first type of side row configuration authorization (type-1SL CG), the terminal device substitutes the PeriodicitySL obtained by Formula 3 into the above Formula 1 to determine the time domain resources of the first side row configuration authorization. Alternatively, in the case where the first side row configuration authorization is a second type of side row configuration authorization (type-2SL CG), the terminal device substitutes the PeriodicitySL obtained by Formula 3 into the above Formula 2 to determine the time domain resources of the first side row configuration authorization.

[0101] In Example 1, if time slot A belongs to a transmission opportunity of the first side row configuration grant, then time slot A+PeriodicitySL also belongs to the resource pool corresponding to the first side row configuration grant and is also a transmission opportunity of the first side row configuration grant.

[0102] In Example 1, for example, the network device configures the resources available for sideline transmission within 20 ms as follows Fig. 9 and Fig.10 As shown, the first 10ms includes 3 time slots that can be used for sideline transmission, and the second 10ms includes 7 time slots that can be used for sideline transmission. At this time, N = 10. The length of the bitmap used to configure the time domain resources of the resource pool is 15 bits, and one 1 is set for every 3 bits, that is, every 15 time slots that can be used for sideline transmission include 5 time slots belonging to the resource pool, and the first sideline configuration authorization is associated with the resource pool.

[0103] For example, assuming that the first sideline configuration grant is a first type sideline configuration grant (type-1SL CG), and the period of the first sideline configuration grant is 20ms, according to It is calculated that PeriodicitySL = 10. If the network device is configured with sl-TimeOffsetCGType1 = 0, according to the above formula 1, logical time slots 0, 10, 20, 30, ... are the time slots corresponding to the first side configuration authorization. However, according to the resource pool configuration information, time slots 10 and 20 do not belong to the resource pool associated with the first side configuration authorization, as follows Fig. 9 As shown in the fourth row of , these two time slots (time slot 10 and time slot 20) do not belong to the time domain transmission resources corresponding to the first side configuration authorization, and are not the transmission resources available for the first side configuration authorization. Therefore, according to the formula The time domain resources determined for the first side configuration authorization are time slots 0 and 30, and the interval between two adjacent time domain resources authorized by the first side configuration is 30 time slots, ie, 30 ms, which is much larger than the period of 10 ms of the first side configuration authorization configured by the network device.

[0104] For another example, assuming that the first sideline configuration grant is a first type sideline configuration grant (type-1SL CG), and the period of the first sideline configuration grant is 20ms, L=15, k=5, N=10, according to The calculation results in PeriodicitySL=4, that is, the period of the first side configuration authorization is 4 time slots, and the 4 time slots are the 4 time slots in the resource pool associated with the first side configuration authorization. If the network device configures sl-TimeOffsetCGType1=0, according to the above formula 1, the logical time slots 0, 4, 8, 12, ... in the resource pool are the time slots corresponding to the first side configuration authorization, which respectively correspond to the logical time slots 0, 12, 24, 36 in the side transmission time slot set, that is, the interval between two adjacent time domain resources of the first side configuration authorization is 12 time slots, such as Fig.10 As shown, it is closer to the actual cycle value (10ms) configured by the network device.

[0105] Therefore, in Example 1, the period of the first side row configuration authorization configured by the network device is converted into the number of time slots corresponding to the period of the first side row configuration authorization in the resource pool associated with the first side row configuration authorization through the above formula 3, so that the time slot belonging to the first side row configuration authorization is determined in the resource pool associated with it in the transmission resource determination formula of the first side row configuration authorization, thereby avoiding the situation where a time slot does not belong to the resource pool associated with the first side row configuration authorization.

[0106] Optionally, as Example 2, the first information includes an average number of logical time slots used for sideline transmission in a radio frame. That is, the terminal device can determine the time domain resources authorized by the first sideline configuration according to the average number of logical time slots used for sideline transmission in the radio frame.

[0107] Optionally, in Example 2, the average number of logical time slots used for sideline transmission in one radio frame includes:

[0108] The average value of the number of logical time slots used for sideline transmission in the first radio frame within the time range of the dual SFN and the number of logical time slots used for sideline transmission in the second radio frame within the time range of the dual SFN.

[0109] In Example 2, the average number of logical time slots used for sideline transmission in one radio frame can be obtained by the following formula 4:

[0110] averagenumberOfSLSlotsPerFrame=(numberOfSLSlotsFirstFrame+numberOfSLSlotsSecondFrame) / 2 Formula 4

[0111] Among them, averagenumberOfSLSlotsPerFrame represents the average number of logical time slots used for sideline transmission in a radio frame, numberOfSLSlotsFirstFrame represents the number of logical time slots used for sideline transmission in the first radio frame within the time range of the dual SFN, and numberOfSLSlotsSecondFrame represents the number of logical time slots used for sideline transmission in the second radio frame within the time range of the dual SFN.

[0112] It should be noted that, in Example 2, the time domain resources authorized by the first sideline configuration can be determined by replacing the numberOfSLSlotsPerFrame in the above Formula 1 and Formula 2 with the averagenumberOfSLSlotsPerFrame.

[0113] Therefore, in Example 2, the time domain resources authorized by the first sideline configuration are determined based on the average number of logical time slots used for sideline transmission in a radio frame, thereby avoiding the problem of different numbers of numberOfSLSlotsPerFrame in each radio frame.

[0126] Wherein, in Formula 6, DoubleSFN represents the SFN index within the time range of the double SFN, for example, the index range of the SFN is [0,1023], that is, 1024 radio frames are included in 10240 ms, and the index range of DoubleSFN is [0,511]; numberOfSLSlotsPerDoubleFrame represents the number of logical time slots used for side transmission within the time range of the double SFN; logical slot number in the double frame represents the index of the logical time slot used for side transmission within the time range of the double SFN; DoubleSFN start time Indicates the index of the dual SFN corresponding to the first transmission opportunity in the first sideline configuration grant; slot start time Represents the index of the logical time slot within the time range of the dual SFN corresponding to the first transmission opportunity in the first side configuration authorization; S is an arbitrary integer; or, N represents the number of logical time slots that can be used for sideline transmission within the time range of the dual SFN, sl_periodCG represents the period of the first sideline configuration authorization configured by the network, k represents the number of values ​​1 in the bit map used to configure the time domain resources of the resource pool, and L represents the total length of the bit map used to configure the time domain resources of the resource pool.

[0127] Therefore, in Example 3, the time domain resources authorized by the first sideline configuration are determined based on the time range of the dual SFN, thereby avoiding the problem of different numbers of numberOfSLSlotsPerFrame in each radio frame.

[0128] Optionally, as Example 4, the first information includes an offset value in the time domain between the target side transmission resource in the first side transmission configuration authorization and the first side transmission resource. That is, the terminal device can determine the time domain resource of the first side transmission configuration authorization based on the offset value in the time domain between the target side transmission resource in the first side transmission configuration authorization and the first side transmission resource.

[0129] Optionally, in Example 4, when the first side row configuration authorization is a first type of side row configuration authorization (type-1SLCG), the terminal device may determine the time domain resources of the first side row configuration authorization based on the following formula 7.

[0130] [(SFN×numberOfSLSlotsPerFrame)+logical slot number in the frame]=

[0131] (timeReferenceSFN×numberOfSLSlotsPerFrame+sl-TimeOffsetCGType1+T+S×PeriodicitySL)modulo(1024×numberOfSLSlotsPerFrame) Formula 7

[0134] [(SFN×numberOfSLSlotsPerFrame)+logical slot number in the frame]=

[0135] [(SFN start time ×numberOfSLSlotsPerFrame+slot start time )+T+S×PeriodicitySL]modulo(1024×numberOfSLSlotsPerFrame) formula 8

[0136] In Formula 8, or, N represents the number of logical time slots that can be used for side transmission in a time range of 20ms, sl_periodCG represents the period of SL CG configured by the network, k represents the number of 1s in the bitmap used to configure the time domain resources of the resource pool, and L represents the total length of the bitmap used to configure the time domain resources of the resource pool; numberOfSLSlotsPerFrame represents the number of logical time slots that can be used for side transmission in a radio frame; logical slot number in the frame represents the number of logical time slots in the radio frame; SFN start time Indicates the SFN corresponding to the first PSSCH transmission opportunity in the CG resource; slot start time It represents the logical time slot corresponding to the first PSSCH transmission opportunity in the CG resource; sl-TimeOffsetCGType1 represents the time domain offset of type-1CG; T represents the offset value in the time domain between the target sideline transmission resource in the first sideline configuration authorization and the first sideline transmission resource; S represents any integer.

When two side transmission resources are included in one cycle of the first side transmission configuration authorization, for example, the time slots corresponding to the two side transmission resources are t1 and t2 respectively, that is, the target side transmission resource is the second side transmission resource, in this case, T=t2-t1, that is, after the terminal device determines the time slot t1 corresponding to the first side transmission resource, the time slot t2 corresponding to the target side transmission resource can be determined based on T. In the case where three side transmission resources are included in one cycle of the first side transmission configuration authorization, it is assumed that the time slots corresponding to the three side transmission resources are t1, t2 and t3 respectively. For example, when the target side transmission resource is the second side transmission resource, T=t2-t1, that is, after the terminal device determines the time slot t1 corresponding to the first side transmission resource, the time slot t2 corresponding to the target side transmission resource can be determined based on T; for another example, when the target side transmission resource is the third side transmission resource, T=t3-t1, that is, after the terminal device determines the time slot t1 corresponding to the first side transmission resource, the time slot t3 corresponding to the target side transmission resource can be determined based on T.
