In order to better understand the technical solution of the present application, the following contents are firstly introduced:

Introduction to V2X

As shown in Figure 1a, the LTE system supports SL transmission, that is, data transmission is directly performed on the physical layer between UEs. LTE sidelink is based on broadcast communication. Although it can be used to support basic security communication of V2X, it is not suitable for other more advanced V2X services. The 5G NR system will support more advanced sidelink transmission designs, such as unicast, multicast or multicast, etc., so as to support more comprehensive types of services.

Resource allocation

NR V2X defines two resource allocation modes (mode), one is mode1, which schedules resources for the base station; the other is mode2, and the UE decides what resources to use for transmission. At this time, the resource information may come from a broadcast message of the base station or pre-configured information. If the UE works within the range of the base station and has a radio resource control (Radio Resource Control, RRC) connection with the base station, it can be mode1 and/or mode2. If the UE works within the range of the base station but has no RRC connection with the base station, it can only work in mode2 . If the UE is outside the range of the base station, it can only work in mode2 and perform V2X transmission according to pre-configured information.

For mode 2, the specific working method is as follows: 1) After the resource selection is triggered, the TX UE first determines the resource selection window, the lower boundary of the resource selection window is T1 time after the resource selection is triggered, and the upper boundary of the resource selection is after the trigger The T2 time, where T2 is the value selected by the UE implementation in the packet delay budget (packet delay budget, PDB) of its transport block (Transport Block, TB) transmission, and T2 is not earlier than T1. 2) UE selects resources in resource selection Before the resource selection, it is necessary to determine the candidate resource set (candidate resource set) for resource selection, and compare the Reference Signal Received Power (RSRP) measured on the resource within the resource selection window with the corresponding RSRP threshold (threshold) , if the RSRP is lower than the RSRP threshold, then the resource can be included in the candidate resource set. 3) After the resource set is determined, the UE randomly selects transmission resources from the candidate resource set. In addition, the UE may reserve transmission resources for the next transmission in this transmission. The specific process is shown in Figure 1b.

At present, the following problems exist in NR communication:

Question 1: Sidelink positioning is currently not supported;

Question 2: If sidelink positiong is supported, how should the measurement or transmission window corresponding to SL Positioning Reference Signal (SL-PRS) be determined;
