Special management connection between base station and relay stations in multihop relay systems for controlling sleep-mode

摘要

The present disclosure proposes different methods of utilizing dedicated control channels in a multi-hop relay system. For one embodiment of the present disclosure, dedicated control channels may be used to power control communication entities in the multi-hop relay system. For another embodiment of the present disclosure, bandwidth resources of dedicated control channels may be employed to control a sleep mode at a subscriber station. For yet another embodiment of the present disclosure, dedicated control channels of the multi-hop relay system may be exploited for sending multicast and broadcast service messages.
