Abstract

Disclosed is the radio (wireless) communication system providing a radio communication service and the terminal, and more particularly, to a method for restricting a use of particular control channel in an Evolved Universal Mobile telecommunications System (E-UMTS) evolved from the Universal Mobile Telecommunications System (UMTS) or a Long Term Evolution (LTE) system.

Claims

1. A method of communicating data in wireless communication system, the method comprising:

receiving configuration information of a physical channel used for a transmission of a request message;

receiving information related to prohibited condition for the transmission of request message;

determining whether or not the request message is capable to transmit according to the received information; and

performing a next operation according to the determining step.

2. The method of claim 1, wherein the next operation is to transmit the request message on the physical channel based on the received configuration information if the request message is capable to transmit.

3. The method of claim 1, wherein the next operation is to transmit a random access preamble if the request message is not capable to transmit.

4. The method of claim 1, further comprising:

triggering the request message before the determining step.

5. The method of claim 4, wherein the request message is triggered when there is no uplink radio resource for a data transmission.

6. The method of claim 1, wherein the physical channel is a Physical Uplink Control Channel (PUCCH).

7. The method of claim 1, wherein the request message is transmitted to request an uplink radio resource.

8. The method of claim 1, wherein the request message is a Scheduling Request (SR).

9. The method of claim 1, wherein the configuration information of the physical channel and the information related to the prohibited condition are received simultaneously.

10. The method of claim 1, wherein the prohibited condition is associated with at least one of time alignment timer, a particular timer that restricting a transmission of the request message, and a maximum number of request message transmission.

11. A method of communicating data in wireless communication system, the method comprising:

transmitting configuration information of a physical channel used for a transmission of a request message by a terminal;

transmitting information related to a prohibited condition indicating whether or not the request message is capable to transmit by the terminal; and

receiving the request message on the physical channel based on the configuration information if the prohibited condition is not met or receiving a random access preamble if the prohibited condition is met.

12. The method of claim 11, wherein the physical channel is a Physical Uplink Control Channel (PUCCH).

13. The method of claim 11, wherein the request message is a Scheduling Request (SR).

14. The method of claim 11, wherein the configuration information of the physical channel and the information related to the prohibited condition are transmitted simultaneously.
