example 1

[0085] Example 1: RRC can configure a corresponding P_delta value (that is, the above preset priority offset value) for each CBR range. When the CBR is greater than the CBR threshold, P_delta is 0; otherwise, P_delta adopts the configured value. Wherein, the CBR threshold value is a protocol predefined / network configuration / preconfigured value.

example 2

[0086] Example 2: UE can obtain P_pri according to the priority rule of the second type UE, and the priority of the first type UE is P_pri+P_delta. Wherein, the priority rule for the second type of UE may include: obtaining the priority from the SCI, or obtaining the priority from high-layer signaling.

[0087] The second possible implementation (preferentially excluding the reserved resources of the first type UE)

[0088] Optionally, in this embodiment of the present application, the above-mentioned first resources include: above-mentioned reserved resources of the first-type UEs and reserved resources of the second-type UEs. The above step 201 may include the following step 201a:

[0089] Step 201a: In the case that the priority of the reserved resources of the UE of the first type is the same as the priority of the reserved resources of the UE of the second type, the UE excludes the reserved resources of the UE of the first type.

[0090] Exemplarily, when the UE detects...

Abstract

The embodiment of the invention provides a resource selection method, a resource selection device and user equipment, relates to the technical field of communication, and aims to solve the problem that the performance of PUE is reduced in a scene that the PUE supports a preemption mechanism. The method comprises the following steps: when a predetermined condition is met, determining an alternative resource set according to resource information of a first resource in a resource selection window; selecting a target resource from the alternative resource set; wherein the predetermined condition comprises at least one of the following items: the terminal device detects a reserved resource of a first type of UE, and the UE is the first type of UE; the resource information comprises at least one of the following items: priority information, a measurement result, a measurement threshold and a UE type of the UE to which the first resource belongs.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a resource selection method, device and user equipment. Background technique [0002] Currently, a preemption mechanism is supported in a New Radio (NR) sidelink (sidelink). For example, in the Mode2 resource allocation mode, the resource pre-emption mechanism is supported, that is, when the reserved resources of a UE overlap (for example, partially overlap) with the reserved resources of other UEs with higher priority services, and When the SL-RSRP measurement value of these UEs on the relevant resources is greater than a certain associated SL-RSRP threshold value, the UEs with low-priority services will trigger resource reselection. [0003] In this way, after the pedestrian UE (PUE) is introduced, the preemption mechanism will cause the terminal equipment performing resource selection to preempt the resources of the PUE, thereby degrading the performanc...
