Abstract:
A user terminal (MS) is in wireless communication with a relay station (Access RS), the relay station being in communication with a super-ordinate station such as a base station (MR-BS) such that the user terminal can perform either single-hop communication with the access relay station or multi-hop communication with the super-ordinate station. The system defines at least one specific signal to be used in a bandwidth request for multi-hop and/or single hop communication. When the user terminal needs bandwidth, it issues a bandwidth request to the relay station indicating a single hop or multi-hop communication by including or not including the specific signal. The relay station decides whether or not to issue its own bandwidth request to the super-ordinate station based on the presence or absence of the specific signal.
