Patent ID: 8514792

Claim:
A method for providing an uplink service in a mobile station, comprising: (a) measuring a partial round trip time, wherein the partial round trip time is a time until ACK which is a response to the received TCP data is inputted into an uplink transmission MAC buffer after TCP data are received from a base station; (b) transmitting information on the measured partial round trip time to the base station; (c) receiving resource allocation information—unicast resource allocation information for transmitting the ACK to the base station in the mobile station—from the base station; and (d) transmitting the ACK of the TCP data received from the base station on the basis of the resource allocation information to the base station, wherein the resource allocation information includes information on a unicast chance waiting timer which is a time when the mobile station waits for a unicast uplink access chance allocated from the base station after receiving a request for transmitting the ACK from an upper hierarchy.
