Abstract

There is provided a method for enabling a user equipment to reconfigure a radio link in a wireless communication system. The method includes receiving a radio link reconfiguration message by a higher layer, requesting a lower layer to respond to the radio link reconfiguration message, configuring a response message for the radio link reconfiguration message, the response message decodable by the lower layer and transmitting the response message.

Claims

1. The method for enabling a user equipment to reconfigure a radio link in a wireless communication system, the method comprising:

receiving a radio link reconfiguration message by a higher layer;

requesting a lower layer to respond to the radio link reconfiguration message;

configuring a response message for the radio link reconfiguration message, the response message decodable by the lower layer; and

transmitting the response message.

2. The method of claim 1, wherein the higher layer is a Radio Resource Control (RRC) layer.

3. The method of claim 1, wherein the lower layer is a Medium Access Control (MAC) layer or a physical layer.

4. The method of claim 1, wherein the radio link reconfiguration message comprises information for an allocated radio resource and the response message is transmitted through the allocated radio resource.

5. The method of claim 1, wherein the radio link reconfiguration message comprises information of a predetermined preamble for a Random Access Channel (RACH) and the response message is transmitted through the RACH.

6. The method of claim 1, wherein the response message is transmitted through at least one of a Channel Quality Indicator (CQI) channel, an ACK/NACK channel, a Random Access Channel, a Pilot channel and L1/L2 control channel.

7. The method for enabling a network to configure or reconfigure a radio link in a wireless communication system, the method comprising:

transmitting a radio link configuration message comprising information for an allocated radio resource; and

receiving a response for the radio link configuration message through the allocated radio resource,

wherein the allocated radio resource comprises an uplink channel resource to transmit the response.

8. The method of claim 7, wherein an uplink channel comprises at least one of a Channel Quality Indicator (CQI) channel, a ACK/NACK channel, a Random Access Channel, a Pilot channel and L1/L2 control channel.

9. The method of claim 7, wherein the radio link configuration message is a RRC message.

10. The method of claim 7, wherein the radio link configuration message is transmitted to reconfigure the radio link after the radio link is established.

11. A method for configuring a radio link in a wireless communication system, the method comprising:

receiving a radio link configuration message comprising information for an allocated radio resource;

configuring a response message for the radio link reconfiguration; and

transmitting the response message using the allocated radio resource,

wherein the allocated radio resource comprises an uplink channel resource to transmit the response message.

12. The method of claim 11, wherein the uplink channel resource comprises a physical resource for an uplink physical channel and the response message is transmitted through the uplink physical channel.

13. The method of claim 11, wherein the radio link configuration message is a RRC message.
