摘要：
A method for transmitting and receiving signals in consideration of a time alignment timer and user equipment (UE) for the same are provided. In this method, a UE performs initial transmission or retransmission of an uplink signal using wireless resources corresponding to an uplink grant signal received from a base station only when a time alignment timer of the UE is running. The UE does not transmit a HARQ feedback signal for a downlink signal received from the base station to the base station when the time alignment timer of the UE is not running.
