Abstract: Embodiments of the present disclosure provide a communication method, a base station and a user equipment. The communication method includes: sending, by a base station, a random access response message to a user equipment UE, where the random access response message includes a timing advance command, and a value TA of the timing advance command is NTA/(N*Ts), where, the NTA indicates the amount of the time alignment the UE, the N*Ts indicates a unit granularity for the UE to perform time alignment, the N is greater than 16, and the Ts indicates the smallest time unit. In the present disclosure, the unit granularity for the UE to perform time alignment may be enlarged, so that the UE can use a larger amount of the time alignment when performing the time alignment, thereby supporting the coverage of a cell with a long distance.
Abstract translation: 本公开的实施例提供通信方法，基站和用户设备。 通信方法包括：由基站向用户设备UE发送随机接入响应消息，其中随机接入响应消息包括定时提前命令，并且定时提前命令的值TA为NTA /（N * Ts），其中，NTA表示UE的时间对齐量，N * Ts表示UE执行时间对准的单位粒度，N大于16，Ts表示最小时间单位。 在本公开中，可以扩大UE执行时间对准的单位粒度，使得在执行时间对准时，UE可以使用更大量的时间对准，从而支持长距离的小区的覆盖。

Abstract: A PRACH preamble sequence being sent by the UE is received. An RAR in response to the PRACH preamble sequence is generated. The RAR includes a TA command. The TA command includes an integer value that is greater than 1282. The integer value alone is capable of determining a TA supporting the UE to perform an uplink time alignment. The RAR is then sent to the UE.
Abstract translation: 接收由UE发送的PRACH前导码序列。 产生响应于PRACH前导序列的RAR。 RAR包括TA命令。 TA命令包括大于1282的整数值。仅整数值能够确定支持UE执行上行链路时间对准的TA。 然后将RAR发送到UE。
