A collaborative Hybrid Automatic Repeat reQuest (HARQ) in a broadband wireless communication system using a relay station is provided. A transmitting end includes a distance estimator for estimating a distance to a relay station; a controller for determining whether to execute a collaborative HARQ using the estimated distance to the relay station; and a transmitter for, when the execution of the collaborative HARQ is determined and a retransmission request is received from a receiving end, sending a retransmission packet according to a multiple antenna signal processing scheme by constituting a virtual multiple antenna group with the relay station.

Apparatus and method for collaborative hybrid automatic repeat request (HARQ) in broadband wireless communication using relay station

Power control for uplink channels with non-cooperative and rational mobile stations (MS) provided using game theory. As a game leader, a multi-antenna access point (AP) determines the network parameters (bandwidth and the number of receiving antennas) for the power control game played between the mobile stations (MSs) (follower), so as to maximize the network utility per system resource (bandwidth and antennas).
