Description

Technical Field

[0001] The present application relates to the technical field of vehicle networking, and particularly relates to a channel resource selection method, apparatus, device, and storage medium. Background Art

[0002] The Mode 4 transmission mode of Long-Term Evolution Vehicle-to-Everything (LTE-V2X) is a vehicle-to-vehicle direct connection method using sidelink. In this mode, vehicles need to autonomously select communication resources. When multiple vehicles select the same communication resource, continuous resource collisions will occur, resulting in communication congestion. Traditional methods use a perception-based semi-static scheduling strategy to solve communication congestion linearly. By performing perception before vehicles select communication resources, the probability of resource collisions is reduced.

[0003] However, traditional scheduling strategies generally can only solve the situation where vehicles have the same Resource Reservation Interval (RRI). If different RRI intervals are used between vehicles, the current methods cannot effectively prevent communication resource collisions. Summary of the Invention

[0004] To solve the above problems, the present application provides a channel resource selection method, apparatus, device, and storage medium, which can effectively solve the problem of increased collision probability caused by different RRI intervals between vehicles and effectively prevent communication resource conflicts and collisions.

[0005] In a first aspect, the present application provides a channel resource selection method, which includes:

[0006] S1. At a target moment when a first user equipment selects a channel resource, perform a resource conflict judgment on a resource selection window according to the transmission control information last received from a second user equipment before the target moment;

[0007] Wherein, the transmission control information includes: a second resource reservation interval used by the second user equipment and whether the target subframe to which the transmission control information belongs is the last frame;

[0008] The resource selection window is expressed as: [n + T1, n + T2], where n is the current subframe corresponding to the target moment, T1 is the resource selection delay of the first user equipment, and T2 is the maximum information transmission delay of the first user equipment;

[0009] S2. When the first user equipment determines that the target subframe is not the last frame and, after superimposing the second resource reservation interval on the target subframe, it is within the resource selection window, delete the first resource block corresponding to the target subframe after superimposing the second resource reservation interval from the resource candidate list of the first user equipment;

[0010] S3. The first user equipment determines the possibility that there is any subframe within the resource selection window that is simultaneously occupied by the first user equipment and the second user equipment according to the second resource reservation interval, the current subframe, the target subframe, and the first resource reservation interval used by the first user equipment;

[0011] S4. If there is a possibility that any subframe within the resource selection window is simultaneously occupied, the first user equipment deletes from the resource candidate list the resource blocks within the resource selection window that have the same sub-channel frequency as the sub-channel of the first resource block.

[0012] In a possible implementation manner, step S3 includes:

[0013] S31. Calculate the least common multiple LCM of the first resource reservation interval RRIA and the second resource reservation interval RRIB;

[0014] S32. Calculate the ratio iA of LCM to RRIA and the ratio iB of LCM to RRIA respectively;

[0015] S33. Determine whether there exists any subframe n1, such that for integers i and j, the following conditions are satisfied:

[0016] n + T1 ≤ n0 + (j × RRIB) = n1 + (i × RRIA) ≤ n + T2, and 0 ≤ i ≤ iA, 0 ≤ j ≤ iB;

[0017] If there exists subframe n1, then there is a possibility that any subframe within the resource selection window is simultaneously occupied.

[0018] In a possible implementation manner, the sub-channel frequency of the first resource block corresponding to the target subframe is the sub-channel frequency used by the second user equipment; the method further includes:

[0019] If there is a possibility that any subframe within the resource selection window is simultaneously occupied, then delete from the resource candidate list the resource blocks within the resource selection window that have the same sub-channel frequency as the sub-channel frequency used by the second user equipment.

[0020] In a possible implementation manner, the first resource reservation interval and the second resource reservation interval are different.

[0021] In a second aspect, a channel resource selection device is provided, and the device includes a plurality of functional modules for performing corresponding steps in the channel resource selection method provided in the first aspect.

[0022] In a third aspect, a computing device is provided, which includes a memory and a processor. The memory stores at least one program, and the at least one program is executed by the processor to implement the channel resource selection method provided in the first aspect.

[0031] To further illustrate each embodiment, this application provides drawings. These drawings are part of the disclosure of this application, and are mainly used to illustrate the embodiments and can explain the operating principles of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of this application. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components. The meaning of the term "at least one" in this application is one or more, and the meaning of the term "multiple" in this application is two or more. For example, multiple resource blocks refer to two or more resource blocks.

[0032] The present application will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] The channel resource selection method provided by the embodiments of the present application is applied to the vehicle-to-everything (V2X) scenario, and can be used to prevent channel resource conflict problems that occur when vehicles communicate through sidelink.

[0034] The vehicle-to-everything system involved in the present application uses LTE-V2X for vehicle-to-vehicle direct connection. LTE-V2X uses single-carrier frequency division multiple access, and each channel is divided into multiple subframes in time and multiple subchannels in frequency. The channel resources can be regarded as a kind of time-frequency structure, with the vertical coordinate being subchannels (frequency) and the horizontal coordinate being subframes (time). Based on this, the channel resources are divided into multiple resource blocks (RBs). Exemplarily, each subframe is 1 millisecond (ms) long. An RB is the smallest frequency unit of channel resources that can be allocated to users, and a subchannel can be described as a group of RBs using the same subchannel frequency. The number of RBs in each subchannel is preset by the LTE system.

[0035] In some traditional channel resource selection processes, the vehicle-side user equipment (UE) will create a list of selectable predetermined resource candidates, and the list of resource candidates includes candidate single-subframe resources (CSRs) that can be used in the resource selection window.

[0036] Aiming at the problem that resource collisions cannot be effectively avoided in the scenario where different RRI cannot be used between vehicles in traditional resource selection technologies, the present application proposes a channel resource selection method. Figure 1 It is a schematic flowchart of a channel resource selection method provided by the embodiments of the present application. Figure 1 This method includes the following steps S1 to S4.

[0037] S1. At the target moment of selecting channel resources, the first user equipment judges resource conflicts for the resource selection window according to the transmission control information received from the second user equipment last before the target moment.

[0038] Among them, the transmission control information includes: the second resource reservation interval used by the second user equipment and whether the target subframe to which the transmission control information belongs is the last frame. In the embodiments of the present application, in addition to sending data, the LTE-V2X sidelink also sends transmission control information (SCI), and the SCI includes whether the currently sent data is the last frame and the RRI used by the vehicle sending the information.

[0039] Exemplarily, if a vehicle (UE) needs to reserve a new sub-channel at the current moment to send information to other vehicles, it can reserve channel resources within the resource selection window range [n + T1, n + T2] according to the current sub-frame.

[0040] Based on this, the resource selection window is expressed as: [n + T1, n + T2], where n is the current sub-frame corresponding to the target moment, T1 is the resource selection delay of the first user equipment, and T2 is the maximum information transmission delay of the first user equipment. Exemplarily, T1 ≤ 4ms and T2 ≤ 100ms.

[0041] Exemplarily, the first user equipment (UEA) uses the first resource reservation interval RRIA. Among the 1000 sub-frames before the target moment T, according to the SCI (the target sub-frame to which it belongs is denoted as n0) that UEA finally received from the second user equipment (UEB), it can be determined whether the current is the last frame, and the second resource reservation interval RRIB used by UEB can be determined from the SCI.

[0042] S2. When the first user equipment determines that the target sub-frame is not the last frame and the target sub-frame is within the resource selection window after being superimposed with the second resource reservation interval, the first resource block corresponding to the target sub-frame after being superimposed with the second resource reservation interval is deleted from the resource candidate list of the first user equipment.

[0043] In the embodiments of the present application, the first resource reservation interval RRIA and the second resource reservation interval RRIB are different.

[0044] Specifically, the target sub-frame superimposed with the second resource reservation interval is denoted as: n0 + RRIB. If n0 + RRIB is within the resource selection window [n + T1, n + T2], it means that the second user equipment UEB will continue to use the sub-channel frequency corresponding to the target sub-frame within the future RRIB. Therefore, the sub-channel resources (the first resource block) used by UEB in the sub-frame corresponding to n0 + RRIB will not be included in the CSR candidate list of UEA to prevent communication resource conflicts. The sub-channel resources used by UEB in the sub-frame corresponding to n0 + RRIB are also the first resource block with the time of n0 + RRIB and the sub-channel frequency used by UEB. The first resource block is one of the resource blocks in the sub-channel resources used by URB.

[0045] Figure 2 It is a schematic diagram of a resource block provided by the embodiments of the present application. Refer to Figure 2 , and the shaded rectangular block is the first resource block excluded from the CSR candidate list. The abscissa of the resource block is the sub-frame (time), and the ordinate is the sub-channel (frequency). Through Figure 2 it can be seen that this step S2 excludes one resource block within the interval [n + T1, n + T2].

[0046] S3. The first user equipment determines the possibility that any subframe within the resource selection window is occupied by both the first user equipment and the second user equipment according to the second resource reservation interval, the current subframe, the target subframe, and the first resource reservation interval used by the first user equipment.

[0047] In the embodiments of the present application, this step S3 specifically includes:

[0048] S31. Calculate the least common multiple LCM of the first resource reservation interval RRIA and the second resource reservation interval RRIB.

[0049] S32. Calculate the ratio iA of LCM to RRIA and the ratio iB of LCM to RRIA respectively.

[0050] Exemplarily, iA = LCM / RRIA; iB = LCM / RRIB.

[0051] S33. Determine whether there exists any subframe n1 such that for integers i and j, the following is satisfied:

[0052] n + T1 ≤ n0 + (j × RRIB) = n1 + (i × RRIA) ≤ n + T2, and, 0 ≤ i ≤ iA, 0 ≤ j ≤ iB;

[0053] If there exists a subframe n1, then there is a possibility that any subframe within the resource selection window is occupied simultaneously.

[0054] Through the above simple calculation process, it can be accurately determined whether two different RRIs will cause additional channel resource conflicts.

[0055] S4. If there is a possibility that any subframe within the resource selection window is occupied simultaneously, the first user equipment deletes the resource blocks within the resource selection window that have the same subchannel frequency as the first resource block from the resource candidate list.

[0056] In the embodiments of the present application, if there is a possibility that any subframe within the resource selection window is occupied simultaneously, it indicates that resource collisions may still occur within the resource selection window. Therefore, resource conflicts can be avoided by excluding the entire subchannel frequency used by UEB.

[0057] In a possible implementation manner, the subchannel frequency of the first resource block is the subchannel frequency used by the second user equipment. In this example, if there is a possibility that any subframe within the resource selection window is occupied simultaneously, the resource blocks within the resource selection window that have the same subchannel frequency as the subchannel frequency used by the second user equipment can be directly deleted from the resource candidate list.

[0058] Figure 3 It is a schematic diagram of excluding multiple resource blocks provided by the embodiments of the present application. SeeFigure 3 Among them, each shaded rectangular block is a resource block excluded from the CSR candidate list. The abscissa of the resource block is the subframe (time), and the ordinate is the subchannel (frequency). Through Figure 3 it can be seen that in this step S4, all resource blocks (the entire subchannel) with the same subchannel frequency as that used by UEB can be excluded within the interval [n + T1, n + T2].

[0059] When the technical solution provided by the embodiment of the present application addresses the problem of increased collision probability caused by different RRI values between vehicles, it is only necessary to perform simple calculations to determine the possibility that any subframe within the resource selection window is simultaneously occupied by two user devices, thereby directly excluding the subchannels with conflict risks from the resource candidate list, and completely avoiding the communication resource conflict problem caused by different RRI intervals between vehicles without transmitting additional information in the sidelink.
