20090245164 | Wireless Communication Systems - A wireless communication system comprising at least one user terminal (MS) in wireless communication with a relay station (Access RS), the relay station being in communication with at least one super-ordinate station in the system 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 access relay station's 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, and the specific signal is notified to the user terminal in advance, for example during a network entry procedure conducted with the relay station. This specific signal can be a specific CDMA code (or one of a set of codes), or a distinct CID, reserved for either single or multi-hop. Then, 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. In this way, latency of bandwidth requests is reduced without needless allocation of bandwidth at the super-ordinate station. | 10-01-2009 |
