METHOD FOR MAINTAINING TIME ADVANCE TIMER, BASE STATION AND TERMINAL EQUIPMENT

摘要

A method, base station and terminal device for maintaining a time alignment timer are provided in the embodiments of the present invention. Said method includes: the base station judges whether the bands to be performed uplink adjustment only include the bands of the primary cell; if only include the bands of the primary cell, the base station sends a timing advance command to the bands of the primary cell, to make the time alignment timer corresponding to the bands of the primary cell to restart. The effects of the present embodiments of the present invention are to make the time alignment timer of the bands of the primary cell to expire ultimately by the processing of the base station or terminal device to the time alignment timer, and thus avoiding the termination of the communications as the time alignment timer corresponding to the bands of the primary cell expires in advance.
