Abstract: A method for random access to a base station by a user equipment (UE) in a mobile communication system using carrier aggregation in which communication is conducted over a plurality of component carriers, and a terminal for the method are disclosed. When the UE performs a contention-based random access procedure in the mobile communication system to which CA technology is applied, the UE considers an uplink grant signal as a contention resolution message when receiving the uplink grant signal from a eNB only when the uplink grant signal is received through a downlink CC corresponding to an uplink CC used to transmit a random access preamble or a third message, to thereby prevent contention resolution from being erroneously ended.

Abstract: A method of generating a data block for performing a polling procedure in a wireless communication system, a method of transmitting data and a method of performing a polling procedure are disclosed. A protocol layer performs the polling procedure for requesting a receiving side to transmit status report if there are no data to be transmitted to the receiving side in both a transmission buffer and a retransmission buffer. When determining whether there are no data to be transmitted to the receiving side in the retransmission buffer, it is preferable that a data block for which retransmission request information is not received from the receiving side is excluded.

Abstract: A method of performing a Hybrid Automatic Repeat reQuest (HARQ) operation in a wireless communication system. The method according to one embodiment includes storing a data unit into at least one of a HARQ buffer among all HARQ buffers; and flushing all HARQ buffers when a timer expires. The timer is a time alignment timer (TAT) which is used to control how long a User Equipment (UE) is considered to have an uplink time that is aligned. The stored data unit is a Medium Access Control (MAC) Protocol Data Unit (PDU). The TAT is started when a time advance command (TAC) is received from a network.

Abstract: A method of performing contention resolution associated with a random access procedure. The method according to one embodiment includes transmitting, by the mobile communication terminal, an uplink message containing a cell-radio network temporary identity (C-RNTI) and starting a contention resolution timer; receiving, by the mobile communication terminal, a physical downlink control channel (PDCCH) transmission; and considering, by the mobile communication terminal, a contention resolution successful and stopping the contention resolution timer if a specific condition is satisfied. The mobile communication terminal considers the contention resolution successful and stops the contention resolution timer if the PDCCH transmission is addressed to the C-RNTI and the random access procedure is initiated by a downlink (DL) data arrival. The mobile communication terminal considers the contention resolution successful and stops the contention resolution timer if the PDCCH transmission is addressed to the C-RNTI and contains an uplink (UL) grant.
