Abstract
The present invention provides a method of receiving a timing advance command by a user equipment in a wireless communication system. A terminal receives information on a time advance group from a base station, and also receives the timing advance command corresponding to the time advance group from the base station.
Claims18
An apparatus for receiving a timing advance command in a wireless communication system, the apparatus comprising:
- a transceiver configured to transmit or receive a data;
- a memory configured to store the data;
- and
- a processor configured to cooperate with the transceiver and the memory to:
- receive information related to a time alignment group through a radio resource control (RRC) signaling from a base station;
- and
- receive the timing advance command corresponding to the time alignment group from the base station;
- wherein the timing advance command is received together with a time alignment group identifier after receiving the information related to the time alignment group through the RRC signaling,
- wherein the time alignment group identifier identifies the time alignment group to which the timing advance command is applied, and
- wherein the time alignment group identifier is included in a medium access control (MAC) control element (CE).
