Data transmission method and user equipment for the same
DC CAFCFirst 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;
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; and
transmitting new data to the base station in correspondence with the UL Grant signal received on the specific message, if there is no data stored in the Msg3 buffer when receiving the UL Grant signal on the specific message or the specific message is not 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 adapted to receive an uplink grant (UL Grant) signal from a base station on a specific message; a transmission module adapted to transmit data to the base station using the UL Grant signal received on the specific message; a message 3 (Msg3) buffer adapted to store UL data to be transmitted in a random access procedure; a Hybrid Automatic Repeat Request (HARQ) entity adapted to determine 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; and a multiplexing and assembly entity used for transmission of new data, wherein the HARQ entity acquires the new data to be transmitted from the multiplexing and assembly entity if there is no data stored in the Msg3 buffer when the reception module receives the UL Grant signal on the specific message or the received message is not the random access response message, and controls the transmission module to transmit the new data acquired from the multiplexing and assembly entity using the UL Grant signal received by the reception module on the specific message. - View Dependent Claims (8, 9, 10, 11, 12, 13)
