Abstract:
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.
