METHOD, SYSTEM AND APPARATUS FOR TIMING ADJUSTMENT

摘要

A method, a system and an apparatus for timing adjustment are provided in the present invention, the method for timing adjustment includes: determining whether the service access point AP of the user equipment UE has changed (S101); when the service AP of the UE changes, transmitting a timing adjustment signal to modify the uplink timing of the UE, thus enabling the UE to perform timing adjustment (S102), which reduces uplink signal reception delay by the service AP. Therefore, by the embodiments of the present invention, the system can still use shorter uplink CP (Cyclic Prefix) settings, which reduce inter-symbol interference and inter-sub-carrier interference, thus reducing system overheads and improving system capacity utilization rates.
