Patent Images
1. A method of receiving a timing advance command by a user equipment in a wireless communication system, the method comprising:
- receiving, from a base station, the timing advance command corresponding to a time alignment group; and
applying the received timing advance command to at least one serving cell belonging to the time alignment group,wherein the timing advance command is received together with a time alignment group identifier,wherein the time alignment group identifier identifies the time alignment group to which the timing advance command is applied,wherein the time alignment group identifier is included in a medium access control (MAC) control element (CE), andwherein the MAC CE includes both the time alignment group identifier and the timing advance command.
