Abrégé
(EN)
Methods, systems, and devices for random access channel (RACH) timing in a wireless communication are described. A base station and a user equipment (UE) may perform a RACH procedure to establish a communication link between the base station the UE. The RACH timing associated with the RACH procedure may depend on the numerology used for the RACH procedure and may be conveyed by the base station tothe UE in a control message or via system information. In some cases, the numerology may indicate the RACH timing, which may be used to determine a number of symbols or absolute time to be used for portions of the RACH procedure.

描述了用于在无线通信中的随机接入信道(RACH)时序的方法,系统和设备。基站和用户设备(UE)可以执行RACH过程以在基站与UE之间建立通信链路。与RACH过程相关联的RACH时序可以取决于用于RACH过程的参数集,以及可以由基站在控制消息中或者经由系统信息传送给UE。在一些情况下,参数集可以指示RACH时序,其可以用以确定要用于RACH过程的部分的符号数量或绝对时间。
