Abstract

本公开包括一种定时提前方法、装置、通信设备及存储介质。该方法由终端设备执行，该方法包括：为SL数据配置非零的第一定时提前量(402)。本公开实施例所提供的方法，通过终端设备为SL数据配置非零的第一定时提前量，当NR授权频谱业务与NR Sidelink业务共用同一频段时，NR授权频谱业务对应的UL数据与NR Sidelink业务对应的SL数据在传输时均进行定时提前，避免了上述两种类型的数据冲突的可能性，避免当前传输的定时提前的UL数据与之前传输的未进行定时提前的SL数据发生冲突，保障了数据的成功传输。

The disclosure includes a timing advance method, device, communication equipment and storage medium. The method is executed by a terminal device, and the method includes: configuring a non-zero first timing advance for SL data (402). In the method provided by the embodiments of the present disclosure, the terminal device is configured with a non-zero first timing advance for SL data. When the NR authorized spectrum service and the NR Sidelink service share the same frequency band, the UL data corresponding to the NR authorized spectrum service is the same as the NR Sidelink service. The timing of the SL data corresponding to the business is advanced during transmission, which avoids the possibility of the above two types of data conflicts, and avoids conflicts between the currently transmitted UL data whose timing is advanced and the previously transmitted SL data that has not been timing advanced, ensuring the successful transfer of data.
