Abstract: The present invention relates to a method and to an apparatus for optimizing the power consumption of a terminal in a mobile communication system. The method for optimizing power consumption of a terminal in a mobile communication system comprises: a determination step of determining whether there is a need for changing a configuration for a discontinuous reception operation of the terminal; and a transmission step of transmitting, to a base station, a request message for a change in the discontinuous reception operation, if it is determined that the change is needed.

Abstract: The present invention relates to a transmission of a random access in a specific cell from a plurality of serving cells in a mobile communication system using a carrier aggregation technology, and a method for efficiently transmitting uplink channels other than the random access in another cell. In particular, the method for a terminal to transmit an uplink channel to a base station comprises the steps of: confirming whether an uplink channel for a second carrier having an uplink timing different from a first carrier is included in a subframe transmitting a Random Access Preamble for the first carrier; if included, confirming whether the sum of the electric power required for the transmission of the random access preamble and the electric power required for the transmission of the uplink channel exceeds the maximum transmission electric power of the terminal; and, if exceeding, transmitting the random access preamble preferentially before the uplink channel. In addition, the terminal for transmitting an uplink channel to a base station comprises: a transmitter/receiver for transmitting/receiving a signal to/from the base station; and a control unit for confirming whether the uplink channel for a second carrier having an uplink timing different from a first carrier is included in a subframe for transmitting a random access preamble for the first carrier, and if included, confirming whether the sum of the electric power required for transmitting the Random Access Preamble and the electric power required for transmitting the uplink channel exceeds the maximum transmission electric power of the terminal, and if exceeding, controlling the transmission so that the random access preamble is preferentially transmitted before the uplink channel.

Abstract: The present invention involves defining the operation of a terminal for determining which time alignment timer is to be applied to a certain condition when specific time alignment timers operate for each carrier-wave group in the event a wireless communication system uses a carrier aggregation technique. According to the present invention, a terminal may perform communication without malfunctions using a time alignment timer suitable for a certain condition. A method for a terminal to operate a time alignment timer according to the present invention comprises the steps of: operating a first time alignment timer for a first timing advance group (TAG) including a first cell; operating a second time alignment timer upon receipt of a timing advance command for a second TAG that does not include the first cell; and, if the first time alignment timer has expired, deeming the second time alignment timer to also be expired.
