Indication method for ascending synchronous establishing command in TD-SCDMA system

时分同步码分多址系统中上行同步建立命令的指示方法

Abstract

本发明公开了一种时分同步码分多址系统中上行同步建立命令的指示方法,所述方法包括:A、网络端判断是否需要指示终端进行上行同步,若是,则将高速共享控制信道所携带控制信息中的时隙信息设置为全零来指示所述高速共享控制信道为上行同步建立命令;B、终端接收高速共享控制信道,判断接收到的高速共享控制信道所携带控制信息中的时隙信息是否为全零,若是,则确定所述接收到的高速共享控制信道为上行同步建立命令,进行上行同步过程。依照本发明,能够在不增加HS-SCCH信息域的基础上,通过HS-SCCH指示终端在接收数据前进行上行同步。
The invention discloses an indication method for an uplink synchronous established command in a time-division synchronous code-division multi-access system, which comprises the steps that: A. a network terminal decides whether an indication terminal is required to carry out the uplink synchronization; if the indication terminal is required to carry out the uplink synchronization, then the time slot information in the control information carried by a high-speed sharing control channel is set up to all-zero, so as to indicate that the high-speed sharing control channel is the uplink synchronousestablished command; B. the terminal receives the high-speed sharing control channel and decides whether the time slot information in the control information carried by the high-speed sharing controlchannel is all-zero; if the time slot information is all-zero, then the terminal determines that the received high-speed sharing control channel is the uplink synchronous established command and carries out the uplink synchronization process. According to the indication method, the uplink synchronization can be carried out before receiving data through HS-SCCH on the basis of not increasing the HS-SCCH information domain.
