<p>The invention proposes a method of performing a hybrid automatic repeat request operation for a random access response message. The method at the base station includes the steps of: receiving a contention free random access preamble from a user equipment; transmitting a random access response message to the user equipment in a first media access control protocol data unit; transmitting a second media access control protocol data unit to the user equipment in a hybrid automatic repeat request process of the first media access control protocol data unit including the random access response message, wherein a physical control channel corresponding to the second media access control protocol data unit includes an indicator for indicating that the second media access control protocol data unit includes new data, the indicator being used for indicating whether the media access control protocol data unit is transmitted for a first time or retransmitted.</p> |
