Description

[Technical Field]

[0001] This application claims priority to Chinese Patent Application No. 202310362638.9, filed in China on April 6, 2023, all of which are incorporated herein by reference.

[0002] This application relates to the field of communication technology, and more particularly to sidelink resource allocation methods, apparatus, sidelink equipment, and media. [Background technology]

[0003] Rel-18 is conducting research on the coexistence of LTE (Long Term Evolution, 4th generation mobile communication system) SL (sidelink) and NR (New Radio, 5th generation mobile communication system) SL on the same channel. When adopting a dynamic resource pool sharing approach, the resources used by NR SL User Equipment (UE) to transmit Transport Blocks (TBs) may reside in the same subframe as the resources used by LTE SL UE to transmit TBs. If the NR SL resource pool's SCS (Sub-Carrier Space) is greater than 15 kHz, one LTE SL subframe can contain multiple NR SL slots. In the resource selection method of related technologies Rel-16 / 17, NR SL transmissions are permitted on any slot within a single subframe. This can result in NR SL transmissions existing only on slots other than the first slot, or NR SL transmissions on preceding and succeeding slots within a single subframe originating from different NR SL UEs. The ADC (Analog-to-Digital) adjustment by the AGC (Automatic Gain Control) of the LTE SL UE receiving the LTE SL transmission in that subframe is then affected. The receiver gain of the converter (analog-to-digital converter) can lead to oversaturation for LTE SL transmission in subsequent slots, ultimately resulting in reception failure of LTE SL transmissions and impacting the performance of the LTE SL system. To solve this problem, it is necessary to restrict NR SL transmission to at least one slot within a subframe, and the resource allocation method for NR SL needs to be improved. However, at this stage, there are no specific proposals for improving the resource allocation method for NR SL.

[0004] Furthermore, in dynamic resource pool sharing, the NR SL module in a Rel-18 dual-module device can avoid resources already designated and periodically reserved by the LTE SL module through information shared from the LTE SL module. However, at present, there is no concrete plan to realize dynamic resource pool sharing between LTE SL and NR SL. [Overview of the project] [Problems that the invention aims to solve]

[0013] To clarify the technical problem, technical solution, and advantages that this application aims to solve, they will be described in detail below with reference to the drawings and specific embodiments.

[0014] In the various embodiments of this application, the relative numbers of the following steps do not indicate the order of execution. The execution order of each step should be determined based on its function and underlying logic, and should not be considered limiting to the implementation steps of the embodiments of this application.

[0015] Furthermore, the terms "system" and "network" as used herein are often interchangeable.

[0016] The terms “first,” “second,” etc., in the specification and claims of this application are for distinguishing similar subjects and not for describing a specific order or priority. The data used in this manner are interchangeable where appropriate, so that the embodiments of this application may be carried out in an order other than that illustrated or described herein, and it should be understood that the subjects distinguished by “first,” “second,” etc., usually belong to the same category and do not limit the number of subjects; for example, there may be one or more first subjects. Furthermore, “and / or” in the specification and claims refers to at least one of the subjects being connected, and the symbol “ / ” generally indicates that the subjects related to priority are in an “or” relationship.

[0017] To help those skilled in the art better understand the embodiments of this application, the following explanation will be given first.

[0018] 1. In Rel-18, the same channel may support service transmission by the following three types of devices:

[0019] Type A device: Equipped with both a first wireless access module (NR SL module) and a second wireless access module (LTE SL module), and the LTE SL module can transmit shared information to the NR SL module through interaction within the device.

[0020] Type B devices: These devices either have only an NR SL module, or they include both an NR SL module and an LTE SL module, but the NR SL module cannot obtain shared information from the LTE SL module.

[0021] Type C devices: Equipped only with an LTE SL module.

[0022] The NR SL module can sense and transmit the first physical channel structure (NR SL), but it cannot sense or transmit the second physical channel structure (LTE SL).

[0023] The LTE SL module can detect and transmit LTE SL signals, but it cannot detect or transmit NR SL signals.

[0024] Furthermore, the first side link device in the embodiment of the present application is either a Type A device or a Type B device.

[0025] II. Resource allocation method for NR SL mode-2 NR SL mode-2 employs a distributed resource scheduling method (i.e., UEs autonomously select transmission resources) for resource allocation, and there is no unified scheduling by base stations. Therefore, UEs must determine the resource occupancy status of other UEs through a sensing mechanism and select resources based on the sensing results. The resource selection flow for NR SL mode-2 is as follows.

[0026] Step 1 involves a single candidate slot resource R.x,y is t y which are x + j consecutive subchannels on the slot, where j = 0,..., L subCH is -1. The UE considers any L consecutive subchannels within the time range [n + T1, n + T2] in the corresponding resource pool as one candidate single slot resource. Referring to Figure 1, Figure 1 is a schematic diagram of the sensing window and resource selection window for resource allocation in NR SL mode-2. As shown in Figure 1, 0 ≤ T1 ≤ T subCH and T proc,1 is such that T proc,1 represents the UE's transmission processing delay (including the resource selection time based on sensing, the transmission preparation time of the Physical SideLink Control Channel (PSCCH), and the transmission preparation time of the Physical SideLink Shared Channel (PSSCH)). The value can be in physical slots of {3, 5, 9, 17}, corresponding to SCS {15, 30, 60, 120} kHz respectively. T 2min <if remaining PDB, T 2min ≤ T2 ≤ remaining PDB depends on the UE implementation; otherwise, T2 is equal to remaining PDB. T 2min is the minimum value of T2 set by the upper layer parameter t2min_SelectionWindow, and remaining PDB is the packet delay budget (PDB) of the remaining data packet. The total number of candidate single slot resources is M total is as follows.

[0027] In Step 2, the UE senses the window [n - T0, n - T proc,0The system continuously monitors the slots belonging to the corresponding resource pool within the specified area, excluding slots where its own transmission has occurred. Based on the measurement of the Physical SideLink Control Channel (PSCCH) decoded on the monitored slot and the Reference Signal Received Power (RSRP) performed, the following steps are taken: T0 is the length of the physical sensing window set by the upper layer, and T proc,0 This is the time it takes for the UE to process the previous sensing result, and its value may be {1,1,2,4} physical slots, corresponding to SCS{15,30,60,120}kHz, respectively.

[0028] In Step 3, Th(p i ,p j ) indicates the RSRP threshold corresponding to the i-th RSRP region in sl-ThresPSSCH-RSRP-List-r16, where i=p i +(p j -1)*8, and p i This represents the priority indicated within SCI (Sidelink Control Information), and p j This represents the priority for transmitting UE transmissions, and p j =prio TX That is the case.

[0029] In Step 4, S A Initialize it into a set of all candidate single-slot resources.

[0030] Step 5 involves a single candidate slot resource R. x,y If all of the following conditions are met, then UE is set S A From the candidate single slot resource R x,y Exclude it.

[0034] Step 6 involves a single candidate slot resource R. x,y If all of the following conditions are met, then UE is set S A From the candidate single slot resource R x,y Exclude it.

[0041] In Step 8, UE is S A Report this to the higher levels.

[0042] In Step 9, the upper layer, under the condition that the HARQ RTT and / or retransmission instruction promises are met, sends S for the current TB. A The initial sending resource and the retransmission resource are randomly selected from the available resources.

[0043] 3. LTE SL and NR SL In the LTE SL resource pool time domain setting, the granularity is subframes, and the length of one subframe is 1 ms. On the other hand, in the NR SL resource pool time domain setting, the granularity is slots, and the length of a slot is related to the frequency domain SCS setting, as shown in Table 1.

[0044] [Table 1] Referring to Figure 2, Figure 2 is a flowchart of the sidelink resource allocation method provided in the embodiment of the present application.

[0045] As shown in Figure 2, this method is applied to the first side link equipment. Step 201 determines the candidate resource set, The procedure includes step 202, which performs resource exclusion based on first information of a first wireless access module and / or second information of a second wireless access module, and the candidate resource set.

[0046] In the embodiments of the present application, the first side link device is either a Type A device or a Type B device.

[0047] (1) If the first sidelink device is a Type A device, it is equipped with both an NR SL module and an LTE SL module, and the NR SL module can acquire shared information of the LTE SL module, so step 202 performed by the first sidelink device is Based on the first information of the first wireless access module, the second information of the second wireless access module, and the candidate resource set, resource exclusion is performed. Based on the first information of the first wireless access module and the candidate resource set, perform resource exclusion, and This includes at least one of performing resource exclusion based on the second information of the second wireless access module and the candidate resource set.

[0048] (2) If the first sidelink device is a Type B device, it may have only an NR SL module, or it may have both an NR SL module and an LTE SL module, but the NR SL module cannot obtain the shared information of the LTE SL module, so step 202 performed by the first sidelink device is: This includes performing resource exclusion based on first information of the first wireless access module and the candidate resource set.

[0049] The method for determining the candidate resource set in step 201 may be the methods of step 1 and step 4 of the NR SL mode-2 resource allocation method described above. The candidate resource set in step 202 may further be the candidate resource set after the resource exclusion step of step 5 or step 6 of the NR SL mode-2 resource allocation method described above has already been performed, or it may be the candidate resource set determined in step 201, or it may be the candidate resource set after the resource exclusion method of the embodiment of this application has been performed.

[0050] This document explains the concepts related to this application.

[0051] The physical channel structure corresponding to the NR SL module is the first physical channel structure (NR SL), and the physical channel structure corresponding to the LTE SL module is the second physical channel structure (LTE SL).

[0052] The first information for the NR SL module is the sensing information for the NR SL module, which includes unmonitored slot information and transmission information from the sensed second sidelink device's NR SL module, while the second information for the LTE SL module is the shared information for the LTE SL module.

[0053] The NR SL resource pool is the first resource pool, and the LTE SL resource pool is the second resource pool.

[0054] As a specific implementation, we provide a side-link resource allocation method that is applied to the first wireless access module of the first terminal. The steps include obtaining second information transmitted by the second wireless access module, The steps include determining the set of candidate resources, The procedure includes the step of performing resource exclusion based on first information and second information of the first wireless access module, and a set of candidate resources.

[0055] Here, the first wireless access module obtains second information before selecting a resource.

[0056] Preferably, the second wireless access module transmits the second information to the first wireless access module when it receives sharing request information from the first wireless access module, or the second wireless access module transmits the second information to the first wireless access module on its own initiative before the first wireless access module selects a resource.

[0057] Using the side-link resource allocation method of the embodiment of the present invention, the first side-link device can determine a candidate resource set, and by performing resource exclusion based on the first information of the first wireless access module and / or the second information of the second wireless access module, as well as the candidate resource set, dynamic resource pool sharing between transmissions performed in the first physical channel structure and transmissions performed in the second physical channel structure is realized.

[0058] As a preferred implementation, step 202 is: The step of excluding a first candidate resource from the candidate resource set based on first information of the first wireless access module and / or second information of the second wireless access module, and The process includes at least one of the steps described above, in which a second candidate resource in the set of candidate resources after the first candidate resource has been excluded is excluded, based on first information from the first wireless access module and / or second information from the second wireless access module.

[0059] What can be understood is that when performing resource exclusion based on the first and / or second information, and the candidate resource set, resource exclusion can be performed on the first candidate resource in the candidate resource set, and / or, further, on the second candidate resource in the candidate resource set after the first candidate resource has been excluded.

[0060] A preferred implementation would include one of the following three items in step 201:

[0061] Item 1: Determine the initial candidate resource set to be the set of all candidate resources in the resource selection window. The third candidate resource in the initial candidate resource set is excluded to obtain the candidate resource set, Based on the total number of candidate resources in the aforementioned set of candidate resources, the total number of candidate resources is determined. Item 2: Determine the set of candidate resources within the resource selection window as the aforementioned set of candidate resources. The total number of candidate resources is determined based on the total number of all candidate resources in the aforementioned set of candidate resources, excluding the third candidate resource. Item 3: Determine the total number of candidate resources based on the total number of all candidate resources except for the fourth candidate resource in the resource selection window. Either the set of all candidate resources other than the fourth candidate resource in the resource selection window is determined as the candidate resource set, or the set of all candidate resources corresponding to the total number of candidate resources is determined as the candidate resource set.

[0062] In a preferred embodiment, the third candidate resource is: The resource in the first slot of the target subframe where the third candidate resource is located does not exist in the candidate resource set. The resource in the first slot of the target subframe where the third candidate resource is located does not belong to the first resource pool. The third candidate resource does not exist in the candidate resource set as a resource in the same frequency domain in the first slot of the target subframe where the third candidate resource is located. The resource in the first slot of the target subframe where the third candidate resource is located does not belong to the first resource pool. The subframe in which the third candidate resource is located is the sidelink synchronization signal SLSS subframe of the second physical channel structure, and The slot in which the third candidate resource is located satisfies one of the following conditions: it overlaps with the SLSS subframe of the second physical channel structure.

[0063] In a preferred embodiment, the fourth candidate resource is: The resource in the first slot of the target subframe where the fourth candidate resource is located does not exist in the resource selection window. The resource in the first slot of the target subframe where the fourth candidate resource is located does not belong to the first resource pool. The resource selection window does not contain any resources in the same frequency domain in the first slot of the target subframe where the fourth candidate resource is located. The resource in the first slot of the target subframe where the fourth candidate resource is located does not belong to the first resource pool. The subframe in which the fourth candidate resource is located is the sidelink synchronization signal SLSS subframe of the second physical channel structure, and The slot in which the fourth candidate resource is located satisfies one of the following conditions: it overlaps with the SLSS subframe of the second physical channel structure.

[0064] Figure 3 is a schematic diagram for determining the candidate resource set provided in the embodiment of the present application. In Figure 3, when the SCS of the second resource pool is set to 15 kHz (resource granularity in the time domain is 1 subframe = 1 ms) and the SCS of the first resource pool is set to 30 kHz (resource granularity in the time domain is 1 slot = 0.5 ms), one candidate resource occupies one subchannel. In the embodiment of the present application, the first, second, and third items will be explained below with reference to Figure 3 and the three preferred embodiments described above.

[0065] 1st item: The set of all candidate resources in the resource selection window (excluding resources in SLSS slots or reserve slots, which are indicated by shaded areas in Figure 3) is determined as the initial candidate resource set.

[0066] Since no resource in the same frequency domain in the first slot of the target subframe where any one third candidate resource (shown as a dotted shade in Figure 3) is located exists in the initial candidate resource set, it must be excluded from the initial candidate resource set and a candidate resource set obtained. Similarly, since the resource in the same frequency domain in the first slot of the target subframe where any one third candidate resource (shown as a horizontal line shade in Figure 3) is located is a resource in an NR SLSS slot and does not exist in the initial candidate resource set or belong to the first resource pool, it must also be excluded from the initial candidate resource set and a candidate resource set obtained. Furthermore, since the subframe where any one third candidate resource (shown as a vertical line shade in Figure 3) is located is an LTE SL SLSS subframe, it must also be excluded from the initial candidate resource set and a candidate resource set obtained.

[0067] The total number of candidate resources in the candidate resource set is the total number of candidate resources M. total Let's assume that.

[0068] Second item: The set of all candidate resources within the resource selection window is determined to be the candidate resource set.

[0069] The total number of candidate resources in the candidate resource set, excluding the third candidate resource, is the total number of candidate resources M. total Let's assume that.

[0070] Any resource in the same frequency domain in the first slot of the target subframe where any one third candidate resource (shown as a dotted shade in Figure 3) is located does not exist in the candidate resource set and therefore cannot be counted as one of the total candidate resources. Similarly, any resource in the same frequency domain in the first slot of the target subframe where any one third candidate resource (shown as a horizontal line shade in Figure 3) is located is a resource in an SLSS slot and does not exist in the candidate resource set or belong to the first resource pool, and therefore cannot be counted as one of the total candidate resources. Furthermore, any subframe where any one third candidate resource (shown as a vertical line shade in Figure 3) is located is an LTE SL SLSS subframe and therefore cannot be counted as one of the total candidate resources.

[0071] Third item: The total number of candidate resources in the resource selection window, excluding the fourth candidate resource, is the total number of candidate resources M. total Therefore, any resource in the same frequency domain in the first slot of the target subframe where any one fourth candidate resource (shown as a dotted shade in Figure 3) is located does not exist in the resource selection window and therefore cannot be included as one of the total number of candidate resources. Similarly, any resource in the same frequency domain in the first slot of the target subframe where any one fourth candidate resource (shown as a horizontal line shade in Figure 3) is located is a resource in an SLSS slot and does not exist in the resource selection window or belong to the first resource pool, and therefore cannot be included as one of the total number of candidate resources. Furthermore, any subframe where any one fourth candidate resource (shown as a vertical line shade in Figure 3) is located is an LTE SL SLSS subframe and therefore cannot be included as one of the total number of candidate resources.

[0072] The set of candidate resources in the resource selection window, excluding the fourth candidate resource, is determined as the candidate resource set, or the total number of candidate resources M totalThe set of all candidate resources corresponding to the specified resource is determined as the candidate resource set. Any resource in the same frequency domain in the first slot of the target subframe where any one fourth candidate resource (shown as a dotted shade in Figure 3) is located does not exist in the candidate resource set and therefore cannot be considered a candidate resource. Similarly, any resource in the same frequency domain in the first slot of the target subframe where any one fourth candidate resource (shown as a horizontal line shade in Figure 3) is located is a resource in an SLSS slot and does not exist in the candidate resource set or belong to the first resource pool, and therefore cannot be considered a candidate resource. Furthermore, any subframe where any one fourth candidate resource (shown as a vertical line shade in Figure 3) is located is an LTE SL SLSS subframe and therefore cannot be considered a candidate resource.

[0073] The target subframe is: The target subframe is a subframe that overlaps with LTE SL transmission. The target subframe is a subframe configured in the LTE SL resource pool, and The target subframe satisfies at least one of the following conditions: it is any subframe in the NR SL resource pool where the slot is located.

[0074] The following describes in detail the flow by which the first side-link device performs resource allocation, and includes the following four options.

[0075] Plan 1: In step 1.1, the set of all candidate resources in the resource selection window is determined as the initial candidate resource set.

[0076] In Step 1.2, from the initial candidate resource set, The resource in the first slot of the target subframe where the third candidate resource is located does not exist in the initial candidate resource set, or does not belong to the first resource pool. The resource in the same frequency domain in the first slot of the subframe where the third candidate resource is located does not exist in the initial candidate resource set, or does not belong to the first resource pool. The subframe in which the third candidate resource is located is an LTE SL SLSS subframe, and The candidate resource set is obtained by excluding third candidate resources that satisfy one of the following conditions: the slot in which the third candidate resource is located overlaps with an LTE SL SLSS subframe.

[0077] In step 1.3, the total number of candidate resources in the candidate resource set is defined as the total number of candidate resources, Mtotal.

[0078] In step 1.4, the first candidate resource is excluded from the candidate resource set based on the first and / or second information.

[0079] In step 1.5, from the candidate resource set, The candidate resource in the same frequency domain in the first slot of the target subframe where the second candidate resource is located is either not present in the candidate resource set after the first candidate resource set has been excluded, or has already been excluded. Exclude second candidate resources that satisfy one of the following conditions: the second candidate resource is not contiguous with a candidate resource in the same frequency domain in the first slot on the target subframe where the second candidate resource is located.

[0080] In step 1.6, the total number of candidate resources remaining in the candidate resource set is X*M. total If the value is less than the specified value, increase the RSRP threshold and return to step 1.1 to determine the initial candidate resource set.

[0081] Plan 2: In step 2.1, the set of all candidate resources in the resource selection window is determined to be the candidate resource set.

[0082] In step 2.2, the total number of candidate resources M is calculated by determining the total number of candidate resources, which is the sum of all candidate resources in the set of candidate resources except for the third candidate resource that satisfies one of the following conditions. total year, The resource in the first slot of the target subframe where the third candidate resource is located does not exist in the candidate resource set, or does not belong to the first resource pool. The third candidate resource must not have any resources in the same frequency domain in the first slot of the subframe where it is located, nor must it belong to the first resource pool. The subframe in which the third candidate resource is located is an LTE SL SLSS subframe, and This includes the fact that the slot where the third candidate resource is located overlaps with the LTE SL SLSS subframe.

[0083] In step 2.3, the first candidate resource is excluded from the candidate resource set based on the first and / or second information.

[0084] In step 2.4, from the set of candidate resources after the first candidate resource has been eliminated, The fact that a candidate resource in the same frequency domain in the first slot of the target subframe where the second candidate resource is located does not exist in the candidate resource set after the first candidate resource set has been excluded, or has already been excluded, and Exclude second candidate resources that satisfy one of the following conditions: the second candidate resource is not contiguous with a candidate resource in the same frequency domain in the first slot on the target subframe where the second candidate resource is located.

[0085] In step 2.5, the total number of candidate resources remaining in the candidate resource set is X*M. total If the value is less than the specified value, increase the RSRP threshold and return to step 2.1 to determine the candidate resource set.

[0086] Plan 3: In step 3.1, the total number of candidate resources in the resource selection window, excluding the fourth candidate resource that satisfies one of the following conditions, is calculated as the total number of candidate resources M. total year, The resource in the first slot of the target subframe where the fourth candidate resource is located does not exist in the resource selection window or does not belong to the resource pool. The fourth candidate resource must not have any resources in the same frequency domain in the first slot of the subframe where it is located, either within the resource selection window or not belonging to the resource pool. The subframe in which the fourth candidate resource is located is an LTE SL SLSS subframe, and This includes the fact that the slot where the fourth candidate resource is located overlaps with the LTE SL SLSS subframe.

[0087] In step 3.2, the set of candidate resources is determined to be the set of all candidate resources in the resource selection window except for the fourth candidate resource that satisfies one of the following conditions, or the total number of candidate resources M. total The set of all candidate resources corresponding to is determined as the candidate resource set. The resource in the first slot of the target subframe where the fourth candidate resource is located does not exist in the resource selection window or does not belong to the resource pool. The fourth candidate resource must not have any resources in the same frequency domain in the first slot of the subframe where it is located, either within the resource selection window or not belonging to the resource pool.

The aforementioned first value is, The aforementioned second target time, The second resource reservation cycle, The third resource reservation cycle, The aforementioned fourth resource reservation cycle, and This is determined based on at least one of the times when the first wireless access module receives the second information.

[0129] The first candidate resource will be described below, with reference to three specific embodiments.

[0130] (Embodiment 1) "The aforementioned first candidate resource or sixth candidate resource and the first target resource overlap in the time domain." The first candidate resource or the sixth candidate resource overlaps with the second target resource. This refers to the fact that the slot in which the first candidate resource is located, or the first slot, overlaps with the first target subframe in the time domain.

Here, P in Figure 5 rxvp_RX_LTE This is the second resource reservation cycle, P rxvp_TX_NR This is the first resource reservation cycle.

[0137] In Figures 4 and 5, the first target value satisfies the second type of situation described above, where the second resource reservation cycle is less than one hour, and the value obtained by subtracting the first logic subframe time from the first time is less than or equal to the product of the first value and the second logic resource reservation cycle.

[0138] Here, T scal represents the first time, and the first value p and the first target value Q are expressed by the following formulas: P = [(Subframe where the second target slot is located - Subframe where the second target time is located) / Second resource reservation period] + 1 = 2 Q=[T scal [Second resource reservation cycle] = 3.

If the subframe in which the second target slot is located does not belong to a logic subframe of the second physical channel structure, then the first time is either the time of the first logic subframe belonging to the logic subframe of the second physical channel structure after the subframe in which the second target slot is located, or the first time is the time of the first logic subframe belonging to the logic subframe of the second physical channel structure after the second target slot.

[0141] (Embodiment 2) "If the first candidate resource or the sixth candidate resource overlaps with the third target resource, This refers to the slot in which the first candidate resource is located, or whether the first slot overlaps with the second target subframe in the time domain.

[0147] As shown in Figure 6, the SCS of the first physical channel structure is 15kHz (resource granularity in the time domain is 1 slot = 1 ms), and the SCS of the second physical channel structure is 15kHz (resource granularity in the time domain is 1 subframe = 1 ms), and Q = 4. If it is determined that they overlap, the time domains completely overlap. Here, P in Figure 6 rxvp_RX_LTE This is one of the resource reservation periods set in the second resource pool, P rxvp_TX_NR This is the first resource reservation cycle.

[0148] As shown in Figure 7, the first physical channel structural SCS is 30kHz (resource granularity in the time domain is 1 slot = 0.5ms), and the second physical channel structural SCS is 15kHz (resource granularity in the time domain is 1 subframe = 1ms), and Q=4. If it is determined that there is overlap, then the time domain will partially overlap. Here, P in Figure 7 rxvp_RX_LTE This is one of the resource reservation periods set in the second resource pool, P rxvp_TX_NR This is the first resource reservation cycle.

[0149] In Figures 6 and 7, the second target value satisfies condition type 6, which is that the third resource reservation cycle is less than 1 hour, and the value obtained by subtracting the second logic subframe time from the first time is less than or equal to the product of the first value and the third logic resource reservation cycle.

[0150] Here, T scal represents the first time, and the first value p and the second target value Q are expressed by the following formulas: P = [(Subframe where the second target slot is located - Subframe where the second target time is located) / Third resource reservation period] + 1 = 2 Q=[T scal [3rd Resource Reservation Cycle] = 4.

[0152] If the subframe in which the second target slot is located belongs to the logic subframe of the second physical channel structure, the first time is the logic subframe time of the second physical channel structure corresponding to the subframe in which the second target slot is located. If the subframe in which the second target slot is located does not belong to a logic subframe of the second physical channel structure, then the first time is either the time of the first logic subframe belonging to the logic subframe of the second physical channel structure after the subframe in which the second target slot is located, or the first time is the time of the first logic subframe belonging to the logic subframe of the second physical channel structure after the second target slot.

[0153] (Embodiment 3) This concerns the case where "the first candidate resource or the sixth candidate resource overlaps with the fourth target resource."

[0159] As shown in Figure 8, the SCS of the first physical channel structure is 15kHz (resource granularity in the time domain is 1 slot = 1 ms), and the SCS of the second physical channel structure is 15kHz (resource granularity in the time domain is 1 subframe = 1 ms), and Q=3. If it is determined that there is overlap, then the time domain will partially overlap. Here, P in Figure 8 rxvp_RX_LTE This is the resource reservation cycle for the second side link equipment, P rxvp_TX_NR This is the first resource reservation cycle.

If it is determined that there is overlap, then there is a partial overlap in the time domain. Here, P in Figure 9 rxvp_RX_LTE This is the resource reservation cycle for the second side link equipment, P rxvp_TX_NR This is the first resource reservation cycle.

[0161] In Figures 8 and 9, the third target value satisfies condition type 8, which is when the fourth resource reservation cycle is less than 1 hour, and the value obtained by subtracting the third logic subframe time from the first time is less than or equal to the product of the first value and the fourth logic resource reservation cycle.

[0162] Here, T scal represents the first time, and the first value p and the third target value Q are expressed by the following formulas: P = [(Subframe where the second target slot is located - Subframe where the second target time is located) / Fourth resource reservation period] + 1 = 2 Q=[T scal [4th Resource Reservation Cycle] = 3.

[0163] T scal This value is obtained by subtracting the second target time from the subframe in which the second target slot (n) is located, where the second target slot is the time when the first sidelink equipment triggers resource allocation of the first physical channel structure, and the second target time is the end subframe (m) of the time window corresponding to the second information.

[0164] If the subframe in which the second target slot is located belongs to the logic subframe of the second physical channel structure, the first time is the logic subframe time of the second physical channel structure corresponding to the subframe in which the second target slot is located. If the subframe in which the second target slot is located does not belong to a logic subframe of the second physical channel structure, then the first time is either the time of the first logic subframe belonging to the logic subframe of the second physical channel structure after the subframe in which the second target slot is located, or the first time is the time of the first logic subframe belonging to the logic subframe of the second physical channel structure after the second target slot.

[0165] Furthermore, since NR SL supports higher SCS and its time-domain resource granularity may be less than or equal to that of LTE SL, resources may either completely overlap or partially overlap in the time domain.

[0166] In a preferred embodiment, the second candidate resource is: The second candidate resource does not exist in the set of candidate resources after excluding the first candidate resource, in the first slot of the target subframe where the second candidate resource is located, The fact that resources in the same frequency domain in the first slot of the target subframe where the second candidate resource is located have already been excluded, and The second candidate resource satisfies at least one of the following conditions: it is not contiguous with a resource in the same frequency domain in the first slot on the target subframe in which the second candidate resource is located.

[0167] The subframe in which the second candidate resource is located is the sidelink synchronization signal SLSS subframe of the second physical channel structure, The slot where the second candidate resource is located overlaps with the SLSS subframe of the second physical channel structure.

[0168] Figure 10 is a schematic diagram of resource exclusion performed on a second candidate resource in a set of candidate resources after the first candidate resource has been excluded, as provided in an embodiment of the present invention. Here, in Figure 10, the SCS of the second resource pool is set to 15kHz (resource granularity in the time domain is 1 subframe = 1ms), and the SCS of the first resource pool is set to 30kHz (resource granularity in the time domain is 1 slot = 0.5ms), with one candidate resource occupying one subchannel. In the embodiment of the present invention, the flow of "resource exclusion performed on a second candidate resource in a set of candidate resources after the first candidate resource has been excluded" will be specifically explained by referring to Figure 10, divided into the following two situations.

[0169] Situation 1: After the first sidelink device excludes a first candidate resource from the candidate resource set based on the first information of the first radio access module and / or the second information of the second radio access module, as shown in Figure 10, any one second candidate resource (shown as a dotted shaded area in Figure 10) must be excluded from the candidate resource set because no resource in the same frequency domain exists in the first slot of the target subframe where it is located. Similarly, any one second candidate resource (shown as a horizontal line shaded area in Figure 10) must be excluded from the candidate resource set because the resource in the same frequency domain in the first slot of the target subframe where it is located is an NR SLSS slot resource and does not exist in the candidate resource set. Furthermore, any one second candidate resource (shown as a vertical line shaded area in Figure 10) must be excluded from the candidate resource set because the subframe where it is located is an LTE SL SLSS subframe.

[0170] For example, in Figure 10, the resource in the same frequency domain in the first slot of the target subframe where the second candidate resource 1 is located has already been excluded and does not exist in the candidate resource set. Therefore, the second candidate resource 1 must be excluded from the candidate resource set. Conversely, if the situation is reversed, there is no need to exclude candidate resource 2.

[0171] Situation 2: If the third or fourth candidate resource is not already present in the candidate resource set (indicated by the dotted shading, horizontal shading, and vertical shading in Figure 10), the first sidelink device, based on the first information of the first radio access module and / or the second information of the second radio access module, performs resource exclusion on the first candidate resource in the candidate resource set. For example, if the resource in the same frequency domain in the first slot of the target subframe where the second candidate resource 1 is located in Figure 10 has already been excluded and is not present in the candidate resource set, then the second candidate resource 1 must be excluded from the candidate resource set. Conversely, if the opposite is true, then candidate resource 2 does not need to be excluded.

[0172] In a preferred embodiment, the method is performed before step 201, Further including determining the start time of the resource selection window, the start time of the resource selection window is The following conditions are met: if the start time of the resource selection window belongs to the first resource pool, then the start time of the resource selection window is the first slot on a subframe; otherwise, the first slot belonging to the first resource pool after the start time of the resource selection window is the first slot on a subframe.

[0173] Figure 11 is a schematic diagram 1 for determining the start time of the resource selection window, provided in an embodiment of the present invention, and Figure 12 is a schematic diagram 2 for determining the start time of the resource selection window, provided in an embodiment of the present invention. Here, in Figures 11 and 12, when the SCS of the second resource pool is set to 15kHz (resource granularity in the time domain is 1 subframe = 1ms) and the SCS of the first resource pool is set to 30kHz (resource granularity in the time domain is 1 slot = 0.5ms), one candidate resource occupies one subchannel.

[0174] As shown in Figures 11 and 12, the first slot belonging to the first resource pool at the start time n+T1 of the resource selection window and thereafter is the first slot on one subframe.

[0175] In a preferred embodiment, the method is performed before step 201, Further comprising determining the SLSS slot configuration of a first physical channel structure, the SLSS slot configuration being used to determine a first resource pool, and the SLSS slots of the first physical channel structure are If a subframe contains one SLSS slot, then the SLSS is the last slot on that subframe. If a subframe contains one SLSS slot, the SLSS is any slot other than the first slot on that subframe. If a subframe contains multiple SLSS slots, then the multiple SLSSs are multiple consecutive slots on a single subframe, including the last slot. If a subframe contains multiple SLSS slots, then the multiple SLSSs are any multiple slots other than the first slot on that subframe, and If a subframe contains multiple SLSS slots, then the multiple SLSSs satisfy at least one of the following conditions: all slots on the subframe are occupied consecutively.

[0176] Figure 13 is schematic diagram 1 of the SLSS slot setting of the first physical channel structure provided in the embodiment of the present application, Figure 14 is schematic diagram 2 of the SLSS slot setting of the first physical channel structure provided in the embodiment of the present application, and Figure 15 is schematic diagram 3 of the SLSS slot setting of the first physical channel structure provided in the embodiment of the present application. Here, in Figures 13 to 15, the SCS of the second resource pool is set to 15 kHz (resource granularity in the time domain is 1 subframe = 1 ms), and the SCS of the first resource pool is set to 60 kHz (resource granularity in the time domain is 1 slot = 0.25 ms).

[0177] If a subframe contains only one SLSS slot, the SLSS is any slot other than the first slot on that subframe, as shown in Figure 13.

[0178] If a single subframe contains multiple SLSS slots, as shown in Figure 14, the SLSS is any slot other than the first slot on that subframe.

[0179] When a single subframe contains multiple SLSS slots, as shown in Figure 15, an SLSS is a series of consecutive slots on a single subframe, including the last slot.

[0181] Furthermore, after the physical layer performs resource exclusion, it reports a set of candidate resources to the upper layer, which then selects a fifth candidate resource for the required number of minutes of transmission. Subsequently, when PSCCH and PSSCH transmission is performed on the fifth candidate resource, the primary SCI and / or secondary SCI contain type information of the first sidelink device, and this type information is used to indicate whether the first sidelink device is a Type A device or a Type B device.

[0182] The fifth candidate resource lies within one or more subframes, and within the same subframe, one or more fifth candidate resources must be contiguous or non-contiguous resources in the same frequency domain with respect to the first slot candidate resource within that subframe. Figure 16 is a schematic diagram of the determination of the fifth candidate resource provided in an embodiment of the present invention, in which the SCS of the second resource pool is set to 15 kHz (resource granularity in the time domain is 1 subframe = 1 ms) and the SCS of the first resource pool is set to 60 kHz (resource granularity in the time domain is 1 slot = 0.25 ms). As shown in Figure 16, the transmission of the first sidelink equipment requires four fifth candidate resources, where the different shading in Figure 16 represents different fifth candidate resource selection methods.

[0183] In summary, the sidelink resource allocation method of the embodiment of the present application allows the first sidelink device to acquire first information of the NR SL module and second information of the LTE SL module, and to allocate resources to the different second information, thereby avoiding transmission collisions between the NR SL module and the LTE SL module within the first sidelink device, minimizing resource occupation by LTE SL, reducing resource collisions when LTE SL and NR SL coexist on the same channel, minimizing the impact on the performance of the LTE SL system, avoiding or mitigating the failure of LTE SL to receive AGC due to NR SL transmission, enabling coexistence of LTE SL and NR SL on the same channel, and adapting to potential dynamic changes in the service load of LTE SL and NR SL.
