METHOD AND DEVICE FOR ADJUSTING TIMING ADVANCE IN UPLINK MULTIPLE POINTS RECEPTION |
摘要 |
A method and device for adjusting a timing advance in a communication system composed of a mobile terminal and multiple base stations is provided. The method includes steps: the multiple base stations measures channel latencies and powers of channel responses between the mobile terminal and the multiple base stations separately; the non-serving base station in the multiple base stations reports the channel latency and the power measured to a serving base station; and the serving base station determines the timing advance of the uplink of the mobile terminal according to the channel latency and the power received and the channel latency and the power which are measured by the serving base station itself, and informs the mobile base station of the timing advance. By using the method and the device, the useful power received by the uplink multi-base stations can be optimized, and the interference power can be effectively reduced. |
