Methods of setting up channel in wireless communication system
First Claim
1. A method of establishing a dedicated physical channel of a user equipment (UE) by the UE in a wireless communication system comprising:
- receiving channel configuration information which is required for establishing the dedicated physical channel from a network, wherein the channel configuration information includes resource allocation information for reporting buffer status of the user equipment (UE);
transmitting a first buffer status report to the network by using the resource allocation information if at least one first condition is satisfied, wherein the first buffer status report indicates that the user equipment (UE) establishes the dedicated physical channel;
establishing the dedicated physical channel using the channel configuration information after transmitting the first buffer status report;
transmitting a scheduling request via the dedicated physical channel to the network;
receiving scheduling allocation information from the network;
transmitting a second buffer status report to the network by using the resource allocation information if at least one second condition is satisfied, wherein the second buffer status report indicates that the user equipment (UE) releases the dedicated physical channel; and
releasing the dedicated physical channel after transmitting the second buffer status report.

Abstract
A method of establishing a channel in a wireless communication system is disclosed. The method of establishing a dedicated channel of a user equipment in a wireless communication system includes, receiving channel configuration information which is required for establishing the dedicated channel from a network, transmitting a first status report to the network if at least one first condition is satisfied, and establishing the dedicated channel using the channel configuration information after transmitting the first status report. As a result, the wireless communication system can increase its scheduling efficiency using buffer status information of the UE.

2. A method of controlling configuration of a dedicated physical channel of a user equipment (UE) by a network in a wireless communication system comprising:
-
transmitting channel configuration information which is required for establishing the dedicated physical channel to a user equipment (UE), wherein the channel configuration information includes resource allocation information for reporting buffer status of the user equipment (UE); receiving a first buffer status report indicating that at least one first condition is satisfied from the user equipment (UE) by using the resource allocation information, wherein the first buffer status report indicates that the user equipment (UE) establishes the dedicated physical channel; receiving a scheduling request transmitted from the user equipment (UE) via the established dedicated physical channel, which is established using the channel configuration information; transmitting scheduling allocation information to the user equipment (UE); receiving a second buffer status report indicating that at least one second condition is satisfied from the user equipment (UE) by using the resource allocation information; and stopping reception of the dedicated physical channel after receiving the second buffer status report. - View Dependent Claims (8, 9, 10, 11, 15, 16, 17)
