Title:

COMMUNICATION CONTROL METHOD, RADIO COMMUNICATION SYSTEM, BASE STATION, AND MOBILE STATION

Document Type and Number:

WIPO Patent Application WO/2006/016457

Kind Code:

A1

Abstract:

In a radio communication system performing HARQ (hybrid automatic retransmission control), when a mobile station receives ACK, it returns its HARQ processing state to a free state. In this state, when the mobile station receives SA (scheduling assignment) for assigning resources for retransmission from a scheduling base station, the mobile station transmits a transmission process state report reporting that it is in the free state if no new data to be transmitted is present. Thus, the base station recognizes that the mobile station is in the free state and resets its HARQ processing state to the free state and stops resource assignment to the mobile stations.
