Abstract

Provided in the present application are a wireless communication method, apparatus, device and storage medium, the method comprising: when a first terminal device sends SL data on a randomly selected time-frequency resource block, monitoring feedback information of an SL HARQ on a PSFCH, the feedback information of the SL HARQ comprising a number of NACK feedback times; when it is detected that the NACK feedback frequency in the feedback information is larger than a first threshold value, the L1 priority level of the SL data is improved according to the NACK feedback frequency, and an updated L1 priority numerical value is obtained; and sending auxiliary link control information SCI to the second terminal device through the network device, the SCI carrying the updated L1 priority value, and the SCI being used for instructing the second terminal device to re-determine a resource selection mode of the second terminal device according to the updated L1 priority value. Therefore, the time-frequency resource block selected by the second terminal device according to the re-determined resource selection mode is different from the time-frequency resource block randomly selected by the first terminal device at present, continuous resource collision can be effectively avoided, and the transmission efficiency of the resource pool is improved.

Description

technical field

[0001] The present application relates to the technical field of communication, and in particular to a wireless communication method, device, equipment and storage medium. Background technique

[0002] With the rapid development of Vehicle-to-Everything (V2X) requirements, the 3rd Generation Partner Project (3GPP) has also begun to formulate NR V2X standard protocols under the framework of the 5G NR system. 3GPP identified 4 major use case groups for 5G V2X, including: automatic queuing driving, support for extended sensing, semi-autonomous or fully automatic driving and remote driving. When a V2X user equipment (User Equipment, UE) resides in a cell, the V2X UE will use the secondary link (Sidelink, SL) resource pool (Resource Pool) configured in the current cell for data transmission; when the V2X UE is in the cell coverage In addition, the V2X UE will use the pre-configured SL resource pool for data transmission.

[0003] In the LTE V2X system, the SL re...
