Relaying radio communication between a base station and a mobile terminal using a control channel at a longer time interval
First Claim
1. A method for relaying radio communication between abase station and a mobile communication terminal device located within a service area of the base station by carrying out a relaying function transmitting a control channel transmitted from the base station to the mobile communication terminal device, comprising the steps of:
- receiving a control channel at a first transmitting interval transmitted from the base station; and
transmitting the control channel to the mobile communication terminal device at a second transmitting time interval, the second transmitting time interval being set longer than the first transmitting time interval.

Abstract
A repeater terminal usually functions as a mobile terminal served by a base station for radio communication. The repeater terminal receives a control channel at a time interval from the base station. The repeater terminal, when operating as a relaying station for another mobile terminal, sends out the control channel thus received to the other mobile terminal at a time interval longer than the interval at which it receives the control channel from the base station. The mobile terminal carries out intermittent reception at the longer time interval in timed with the control channel sent out from the repeater terminal, thereby reducing its electric power consumption.
