Abstract

A method allowing a terminal with data to be transmitted in an uplink direction to transmit a radio resource allocation request message to a base station by effectively using radio resource(s) to its maximum level is disclosed. In particular, the method allows the terminal to select a radio resource allocation request message of a proper format according to a situation of radio resource(s) or the amount of data of each channel and transmit the same to the base station.

Claims

1. A Method for communicating data in a wireless communication system, the method comprising:

defining a plurality of buffer status report (BSR) formats for a transmission of a BSR;

selecting one of the plurality of BSR formats based on a certain condition;

generating a BSR according to the selected buffer status report format; and

transmitting the generated BSR.

2. The method of claim 1, wherein the plurality of BSR formats comprise a normal BSR and a shortened BSR.

3. The method of claim 2, wherein the normal BSR is selected if an uplink radio resource is allocated enough to include information with respect to all configured channels or all configured channel groups.

4. The method of claim 2, wherein the shortened BSR is selected if an uplink radio resource is allocated not enough to include information with respect to all configured channels or all configured channel groups.

5. The method of claim 2, wherein the normal BSR includes buffer information about every channel set for the terminal.

6. The method of claim 2, wherein the normal BSR includes buffer information about every logical channel or logical channel group set for the terminal.

7. The method of claim 2, wherein the shortened BSR includes buffer information about some of all the channels set for the terminal.

8. The method of claim 2, wherein the shortened BSR comprises buffer information about every logical channel, some channels or some channel groups of logical channel groups.

9. The method of claim 2, wherein the shortened BSR is used while the random access procedure is performed.
