The present invention relates to a method, a
system and an apparatus for implementing
bandwidth allocation and scheduling management based on a
relay station. A mapping information unit for controlling a RS (MAPRS) is set in a frame structure of the
physical layer of a BS and an extended frame structure of the
physical layer of a BS is constructed in a frame structure of the BS
physical layer. The BS constructs a mapping information message MAPRS for controlling the
relay station RS base on the extended frame structure of the BS physical layer, and performs
bandwidth allocation and scheduling management of a
communication channel of the RS by the RS according to the MAPRS message. Through the present invention, a
bandwidth allocation is implemented mainly at the BS, and a service scheduling is implemented mainly at the BS. The RS only performs an uplink or
downlink scheduling of the RS passively. The complexity of the RS reduced effectively. The Multi-hop
relay problem is solved using a bandwidth request relay and a bandwidth allocation relay, without introducing any complex technologies and procedures of the bandwidth request, the bandwidth allocation and the scheduling management. The complexity of the BWA
relay network is simplified.
