AI Technical Summary
Technical Problem
The prior art cannot effectively count the number of transmissions of positioning reference signals (PRS) in side link communication, resulting in the inability to perform congestion control, affecting the system communication performance.
Method used
By determining the SL PRS sent using the appointment resource and counting it as a retransmission, statistics of the number of transmissions of the SL PRS are implemented, thereby supporting congestion control for the SL PRS.
Benefits of technology
It realizes accurate statistics on the number of transmissions of SL PRS, supports effective congestion control, and improves system communication performance.

Abstract
The sidelink communication method and the sidelink communication device provided by the embodiment of the invention are used for counting the transmission times of the SL PRS. The sending end terminal equipment determines to send a first SL PRS by using a first resource, the first resource is a resource reserved by an SCI corresponding to a second SL PRS, and the second SL PRS is sent before the first SL PRS; and determining that the transmission number of times corresponding to the first SL PRS is the transmission number of times corresponding to the second SL PRS plus 1. According to the scheme, the SL PRS sent by using the previously transmitted resource reserved by the SCI is counted as one-time retransmission, and statistics of the transmission times of the SL PRS is realized, so that the execution of congestion control on the SL PRS can be supported, and the communication performance of the system can be improved.
