Abstract: A method of efficiently processing a random access response message, when a terminal (or user equipment) performs random access, is disclosed. After the terminal transmits a random access preamble to a base station, the terminal may receive a random access response message having a format of medium access control protocol data unit (MAC PDU) including only a backoff indicator subheader in a MAC header of the MAC PDU, from the base station in response to the random access preamble. As described above, the terminal, which has received the random access response message including only a backoff indicator subheader in the MAC header of the MAC PDU, may consider a random access response reception procedure not successful and may perform a subsequent procedure for a random access responses reception failure.

Abstract: 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.

Abstract: A timer for processing data blocks is proposed for a receiver of a mobile communications system. If the timer is not running, the timer is started based a data block. The data block has a sequence number higher than a sequence number of another data block that was first expected to be received. If the timer is stopped or expires, the timer is based on a highest sequence number of a data block among data blocks that cannot be delivered to a higher entity. The timer can be used to prevent a stall condition in mobile communications.
