Реферат: Methods and apparatus are provided for beamforming and information feedback are provided. Signals for beams to be transmitted through corresponding antenna ports, are generated. The beams are formed by precoding the signals with beamforming vectors. The beams are sorted into a number of resource reuse groups based on a resource that is to be shared. The beams are transmitted, using resources allocated per group, to a receiver. Feedback information is generated on at least one antenna port, based on the received beams. The feedback information is transmitted to the transmitter. A beam is selected having a greatest gain for a transmitter using the feedback information. A transmission resource is allocated for the selected beam.
