METHOD, SYSTEM AND APPARATUS FOR TIMING ADJUSTMENT

摘要

A method, a system and an apparatus for adjusting timing are disclosed. The method includes: judging (S101) whether an Access Point (AP) in service of a User Equipment (UE) changes; and sending (S102) timing adjustment signaling to correct uplink timing of the UE if an AP in service of the UE changes, so as to enable the UE to adjust the timing, thereby shortening delay of the uplink signals received by the AP in service. By still applying a short uplink CP, the system relieves inter-symbol crosstalk and inter-subcarrier interference, and therefore reduces the system overhead and improves the utilization of system capacity.
