Data transmission method and user equipment for the same

摘要

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.

1. A method of transmitting data by a user equipment through an uplink, the method comprising:
receiving an uplink grant (UL Grant) from a base station; determining whether there is data stored in a message 3 (Msg3) buffer and whether the UL Grant was received on a random access response message; and transmitting, only when there is data stored in the Msg3 buffer and when the UL Grant was received on the random access response message, the data stored in the Msg3 buffer to the base station using the UL Grant received on the random access response message.
