DATA TRANSMISSION METHOD AND USER EQUIPMENT FOR THE SAME
First Claim
1. A method of transmitting data by a user equipment through an uplink, the method comprising:
- receiving an uplink grant (UL Grant) signal from a base station on a specific message;
determining whether there is data stored in a message 3 (Msg3) buffer when receiving the UL Grant signal on the specific message;
determining whether the specific message is a random access response message; and
transmitting the data stored in the Msg3 buffer to the base station using the UL Grant signal received on the specific message, if there is data stored in the Msg3 buffer when receiving the UL Grant signal on the specific message and the specific message is the random access response message.

Abstract
A mobile communication technology, and, more particularly, a method for efficiently transmitting data stored in a message 3 (Msg3) buffer and a user equipment for the same is disclosed. The method of transmitting data by a user equipment in uplink includes receiving an uplink (UP) Grant signal from a base station on a specific message, determining whether there is data stored in a message 3 (Msg3) buffer when receiving the UL Grant signal on the specific message, determining whether the specific message is a random access response message, and transmitting the data stored in the Msg3 buffer to the base station using the UL Grant signal received on the specific message, if there is data stored in the Msg3 buffer when receiving the UL Grant signal on the specific message and the specific message is the random access response message.

7. A user equipment comprising:
-
a reception module receiving an uplink grant (UL Grant) signal from a base station on a specific message; a transmission module transmitting data to the base station using the UL Grant signal received on the specific message; a message 3 (Msg3) buffer storing UL data to be transmitted in a random access procedure; and a Hybrid Automatic Repeat Request (HARQ) entity determining whether there is data stored in the Msg3 buffer when the reception module receives the UL Grant signal and the specific message is a random access response message, acquiring the data stored in the Msg3 buffer if there is data stored in the Msg3 buffer when the reception module receives the UL Grant signal and the specific message is the random access response message, and controlling the transmission module to transmit the data stored in the Msg3 buffer to the base station using the UL Grant signal received by the reception module on the specific message. - View Dependent Claims (8, 9, 10, 11, 12, 13)
