Referring to fig. 1, fig. 1 is a schematic structural diagram of a communication system according to an embodiment of the present application. The communication system may include, but is not limited to, one or more network devices, one or more terminal devices, such as fig. 1 illustrates one network device and two terminal devices, where the network device illustrated in fig. 1 illustrates a base station, the terminal device illustrated in fig. 1 illustrates a vehicle, the terminal device may establish a wireless link with the network device to perform communication, and a side link may also be established between the terminal device and the terminal device to perform communication. The communication system shown in fig. 1 includes, but is not limited to, a network device and a terminal device, and may further include other communication devices, and the number and form of the devices shown in fig. 1 are used for illustration and not to limit the embodiments of the present application.

In the communication system shown in fig. 1, a certain terminal device may perform resource preemption confirmation on a first resource before a time slot where the first resource indicated by reservation is located, and if it is determined that the first resource is not in a candidate resource set and meets a target condition, the first terminal performs resource reselection, so as to reduce the probability of resource collision and improve the success rate of data transmission.

Referring to fig. 2, fig. 2 is a flowchart of a resource selection method according to an embodiment of the present application, where the resource selection method may be applied to the communication system shown in fig. 1. The resource selection method comprises the following steps:

S201, if the first resource is not in the candidate resource set and meets the target condition, the first terminal performs resource reselection, wherein the first resource is the resource indicated by the first terminal reservation.

In the embodiment of the present application, the terminal device in the V2X system acquires the transmission resource in a manner of supporting autonomous resource awareness, and in the present application, the first terminal may be a V2X UE. Autonomous resource sensing means that the V2X UE senses resources in a resource sensing window and excludes resources in a resource selection window according to sensing results to obtain a candidate resource set. The autonomous resource aware process is described below in conjunction with fig. 3:

as shown in fig. 3, assuming that the terminal that is performing resource sensing is UE4, UE4 has a packet arriving at time n, (n-T0, n-Tproc, 0) is a resource sensing window, and (n+t1, n+t2) is a resource selection window. And the UE4 performs resource sensing in the resource sensing window, excludes part of resources in the resource selection window according to the sensing result, and finally determines a candidate resource set.

Optionally, the UE4 may perform resource sensing within the resource sensing window by receiving SCI sent by other UEs, and determining at least one reserved resource of the other UEs according to the resource reservation information in the SCI, and excluding the reserved resource falling within the resource selection window. Firstly, all resources of a resource selection window form an original candidate resource set, the UE4 excludes part of the resources in the original candidate resource set according to a sensing result in a resource sensing window, and the specific resource exclusion process mainly comprises the following two steps:

In step 1, the UE4 cannot perform resource sensing in the time slot in which data is transmitted or received in the resource sensing window, that is, in the time slot, the UE4 has no way to receive SCI transmitted by other UEs, if other UEs transmit data and SCI in the time slot, then the UE4 does not receive the SCI, as shown in the first gray filled rectangular block in fig. 3, that is, the time slot in which the UE4 performs data transmission or reception, in order to solve the problem, the UE4 estimates the time slot that cannot be sensed backwards according to all possible resource reservation periods configured by the resource pool, excludes all possible reserved indicated resources falling in the resource selection window from the original candidate resource set, as shown in fig. 3, estimates according to two reservation periods, respectively, to obtain two gray filled rectangular blocks in the resource selection window, and excludes resources corresponding to the two gray filled rectangular blocks in the resource selection window.

Step 2, UE4 decodes SCI of other UEs (e.g. UE1, UE2, UE 3), obtains resource reservation information of other UEs, measures reference signal received power (Reference Signal Receiving Power, RSRP) of a physical layer side link control channel (Physical Sidelink Control Channel, PSCCH) carrying SCI of other UEs or a physical layer side link shared channel (Physical Sidelink shared Channel, PSSCH) carrying data corresponding to the SCI, excludes resources reserved by the UE in a resource selection window if RSRP is measured to be higher than a threshold, and reserves resources reserved by the UE in the resource selection window if RSRP is measured to be lower than the threshold.

As shown in fig. 3, UE4 measures that the RSRP of UE1 is higher than the threshold, and the RSRP of UE2 and UE3 are lower than the threshold, so that UE4 excludes the resources reserved by UE1 from the original candidate resource set, and the last remaining resources are the last candidate resource set.

If the number of the resources in the candidate resource set does not reach the preset number, the RSRP threshold is increased by 3dB, and then the resource elimination process is executed again until the number of the resources in the candidate resource set reaches the preset number.

After the first terminal obtains the candidate resource set through the resource exclusion procedure, at least one resource may be selected from the candidate resource set for transmitting data, and the at least one resource may have periodicity in a time domain. When the first terminal sends data on the selected resource, at least one reserved indicated resource of the first terminal is indicated to other UE through SCI, and the first resource in the application is the reserved indicated resource of the first terminal.

In order to ensure the reliability of transmission, the first terminal supports preemption confirmation of the resources which are already reserved and indicated, namely, confirms whether the resources which are reserved and indicated are preempted by other UEs, for example, the resources which are also reserved and indicated by other UEs are reserved and indicated by other UEs, or the resources overlap with the resources which are reserved and indicated by other UEs.

For example, for a certain first resource within the slot m that has been reserved for indication, the first terminal may perform preemptive acknowledge at least at the instant of m-T3 (T3.ltoreq.Tplc, 1, tplc, 1 is UE processing time).

The preemption confirmation process may take m-T3 as a trigger resource reselection time, the starting time of the resource selection window in the resource preemption process may be a time after the starting time of the resource selection window in fig. 3 is translated backwards, the ending time of the resource selection window in the resource preemption process may be an ending time of the resource selection window in fig. 3, and step 1 and step 2 of the above-mentioned resource exclusion process are continuously executed to exclude part of resources from the new resource selection window and form a new candidate resource set, where the candidate resource set in the present application is the new candidate resource set, so that the candidate resource set in the present application may refer to the resource set for side transmission determined in the resource selection window when preemption confirmation is performed on the first resource.

If the first resource indicated by the reservation of the first terminal is not in the candidate resource set, it is indicated that in the process of resource elimination, since other UEs, such as the second terminal, have partial or complete overlapping with the first resource, the second resource indicated by the reservation is eliminated in the process of resource elimination, and if the target condition is also met, the first terminal performs resource reselection, and the resource reselection follows the constraint condition of resource selection.

The resource preemption confirmation process of the present application is illustrated in the following with reference to fig. 4a and fig. 4b, where as shown in fig. 4a, for example, the first terminal triggers the resource selection process at time n, and selects two resources, for example, two resources denoted by 1 in fig. 4a are two resources selected by the first terminal, where the first terminal reserves a resource indicating the second transmission when transmitting for the first time, and two resources denoted by 2 in the drawing may be other terminals, for example, two resources selected by the second terminal, as can be seen in the drawing, where the resources indicated by the reservation of the first terminal and the resources indicated by the reservation of the second terminal overlap partially.

In order to ensure the reliability of transmission, the first terminal may perform resource preemption confirmation on the reserved indicated resource at the m-T3 moment, where m reserves a time slot in which the indicated resource is located for the first terminal. As shown in fig. 4b, that is, the first terminal triggers the resource reselection at the m-T3 time, and obtains the candidate resource set through the resource exclusion process (for a description of the specific exclusion process, please refer to the foregoing embodiment), since the resource indicated by the reservation of the second terminal (may be referred to as the second resource) and the resource indicated by the reservation of the first terminal (may be referred to as the first resource) have partial overlap, the second resource is excluded in the resource exclusion process.

The first terminal determines that the resources indicated by the reservation (which may be referred to as first resources) are not in the candidate resource set, and if the target condition is met, the first terminal performs resource reselection, as shown in fig. 4b, where the resources marked 1 after the m time slot are the resources reselected by the first terminal in the candidate resource set.

Wherein the target condition may include at least one of:

A. the first terminal belongs to a first communication system, and the second terminal belongs to a second communication system;

B. the priority of the second terminal is higher than that of the first terminal;

For the above condition B, if the network device is configured with a priority threshold (such as a first threshold), the condition B may include that the priority of the second terminal is higher than the first threshold, and the priority of the second terminal is higher than the priority of the first terminal. Thereby ensuring reliability of high priority transmissions above the priority threshold.

Alternatively, for the above condition a, the first communication system may be a system supporting preemption confirmation, that is, the terminal belonging to the first communication system may perform preemption confirmation on the reserved indicated resource before the time slot where the reserved indicated resource is located, for example, the NR V2X system, and the second communication system may be a system not supporting preemption confirmation, that is, the terminal belonging to the second communication system may not perform preemption confirmation on the reserved indicated resource before the time slot where the reserved indicated resource is located, for example, the LTE V2X system. It will be appreciated that the first communication system and the second communication system may both support a system for preemptive confirmation, which is not limited in this application.

In some alternative embodiments, the first communication system and the second communication system of the present application dynamically share frequency domain resources, where the dynamically sharing frequency domain resources may include one or both of the following: 1) The first communication system and the second communication system are respectively configured with different resource pools, and the first resource pool of the first communication system and the second resource pool of the second communication system are overlapped in a frequency domain; 2) The first communication system and the second communication system share a pool of resources, such as a first pool of resources. Since the first communication system and the second communication system dynamically share the frequency domain resources, there may be an overlap between the first resources of the first terminal reservation indication and the second resources of the second terminal reservation indication belonging to the first communication system.

For example, it may be that the terminal belonging to the first communication system and having a priority below the second threshold dynamically shares the frequency domain resource with the terminal of the second communication system, i.e. the first resource pool may be a resource pool configured by the network device for terminals belonging to the first communication system and having a priority below the second threshold. In the present application, the dynamically shared first resource pool is used only if the priority of the first terminal is lower than the second threshold.

In scenario 1, the target condition may include the condition a, in the process of performing the resource preemption confirmation, the first terminal belonging to the first communication system determines that the first resource indicated by reservation is not in the candidate resource set, determines that there is a second resource indicated by reservation of the second terminal overlapping with the first resource, and the second terminal belongs to the second communication system, and then the first terminal performs resource reselection in the candidate resource set.

The transmission priority of the first terminal in this embodiment may be less than/greater than/equal to the transmission priority of the second terminal. The benefit of this embodiment is that the reliability of the transmission of the second communication system, which may be an NR V2X system, may be ensured as much as possible, and the second communication system may be an LTE V2X system.

In scenario 2, the target conditions may include the condition a and the condition B, and the second threshold is set, and only the terminal belonging to the first communication system and having a priority lower than the second threshold can use the dynamically shared frequency domain resource.

When the priority of the first terminal belonging to the first communication system is lower than a second threshold, and the first terminal performs resource preemption confirmation, if the first resource indicated by reservation is not in the candidate resource set and the preemption terminal is a second terminal belonging to the second communication system, the first terminal performs resource reselection. The first communication system may be an NR V2X system and the second communication system may be an LTE V2X system.

This embodiment ensures transmission of terminals belonging to the first communication system of high priority as much as possible while taking into account that the transmission of terminals of the second communication system is not affected.

In scenario 3, the target conditions may include the condition a and the condition B, if the network device is not configured with the first threshold, when the first terminal belonging to the first communication system performs the resource preemption confirmation, if the first resource indicated by the reservation is not in the candidate resource set, and the preempting terminal is a second terminal belonging to the second communication system, where the priority of the second terminal is higher than that of the first terminal, and then the first terminal performs the resource reselection.

If the network equipment is configured with a first threshold, when a first terminal belonging to a first communication system performs resource preemption confirmation, if the first resource indicated by reservation is not in a candidate resource set, the preempting terminal is a second terminal belonging to a second communication system, the priority of the second terminal is higher than that of the first terminal, and the priority of the second terminal is higher than the first threshold, and then the first terminal performs resource reselection.

In this scenario 3, a second threshold may also be set, and only terminals belonging to the first communication system and having a priority lower than the second threshold, which in this application is lower than the first terminal, may use the dynamic shared frequency domain resource. The first communication system may be an NR V2X system and the second communication system may be an LTE V2X system.

This embodiment ensures as much as possible the transmission of the terminals of the first communication system with high priority and reduces as much as possible the impact on the transmission of the terminals of the second communication system.

In the embodiment of the application, if it is determined that the first resource indicated by the reservation of the first terminal is not in the candidate resource set and meets the target condition, the first terminal performs resource reselection, that is, the first terminal performs resource preemption confirmation before using the first resource to send data, and confirms whether the first resource overlaps with the resources indicated by the reservation of other terminals, thereby reducing the probability of resource collision and improving the success rate of data transmission.
