Patent ID: 8693386

Claim:
In a network including a source node, a relay node, and a destination node, wherein the destination node receives signals transmitted by the source and relay nodes using power on/off beamforming with finite rate feedback of channel state information, one of the source and relay nodes is transmitting at a time, the source node is allocated a portion a of transmitting time and the relay node is allocated a portion 1−α of transmitting time, a method performed by a scheduler of allocating resources to maximize a transmission rate received by the destination node comprising the steps of: a) receiving first partial channel state information characteristic of a first channel between the source node and the relay node, second partial channel state information characteristic of a second channel between the relay node and the destination node, and third partial channel state information characteristic of a third channel between the source node and the destination node; b) determining a value α* of α that maximizes the transmission rate received by the destination node according to the first, second and third partial channel state information; and c) allocating a portion α* of transmitting time to the source node and a portion 1−α* of transmitting time to the relay node.
