COMMUNICATION DURATION CONFIGURING METHOD, RELAY STATION, AND MOBILE COMMUNICATION SYSTEM
First Claim
1. A communication duration configuring method in a mobile communication system including a mobile relay station for relaying a wireless communication between abase station and a mobile station, the method comprising:
- configuring at least any of a downlink communication duration where the relay station receives a transmission signal from the base station by restricting a transmission of a signal from the relay station to the mobile station and an uplink communication duration where the relay station transmits a transmission signal to the base station by restricting a transmission of a signal from the mobile station to the relay station; and
restricting or halting a transmission/reception of a signal to/from the mobile station in a first period from detection of a handover by the relay station until when the communication duration is configured between the relay station and a target base station, and using a desired duration within the first period as the communication duration.

Abstract
A communication duration configuring method is used in a mobile communication system including a mobile relay station for relaying a wireless communication between a base station and a mobile station. The method includes: configuring at least any of a downlink communication duration where the relay station receives a transmission signal from the base station by restricting a transmission of a signal from the relay station to the mobile station and an uplink communication duration where the relay station transmits a transmission signal to the base station by restricting a transmission of a signal from the mobile station to the relay station; and restricting a transmission of a signal with the mobile station in a first period from detection of a handover until when the communication duration is configured between the relay station and a target base station, and using a desired duration within the first period.
