WIRELESS COMMUNICATION SYSTEM, BASE STATION, MOBILE STATION, AND WIRELESS COMMUNICATION METHOD

Title:

WIRELESS COMMUNICATION SYSTEM, BASE STATION, MOBILE STATION, AND WIRELESS COMMUNICATION METHOD

Document Type and Number:

WIPO Patent Application WO/2013/024529

Kind Code:

A1

Abstract:

A base station (10) sends first resource-allocation information to a mobile station (20) in response to a scheduling request from said mobile station (20). The base station (10) also sends the mobile station (20) second resource-allocation information on the basis of a buffer state reported by the mobile station (20) using the first resource-allocation information. The base station (10) has a reception unit (111) and a processor (12). The reception unit (111) receives data sent from the mobile station (20) using the second resource-allocation information. The processor (12) receives the abovementioned scheduling request from the mobile station (20) before the completion of the reception of the amount of data indicated by the buffer state reported by the mobile station (20), and if a prescribed condition is met, the processor sends the second resource-allocation information to the mobile station (20) without sending the first resource-allocation information.
