Abstract: The present disclosure provides a method of selecting a plurality of sets of beam pairs in a wireless communication system. The method includes estimating, by a receiver, channels associated with a plurality of transmit ports for each receive port of a plurality of receive ports; and determining, by the receiver, the plurality of sets of the beam pairs including transmit beam and receive beam using: an average power level at each receive port for at least one transmit port based on the estimated channel associated between the beam pairs, a set of first power matrices, wherein each first power matrix, from the set of first power matrices, comprises at least one transmit port, beam ID pairs including transmit beam ID and receive beam ID associated with each receive port, wherein the set of first power matrices is formed based on the average power level at each of the receive port, and a second capacity matrix formed based on capacity maximization obtained from the set of first power matrices, wherein the plurality of sets of the beam pairs associated with each of the transmit port and receive port is selected from the second capacity matrix.

Abstract: The present disclosure provides a method of selecting a plurality of sets of optimal beam pairs in a wireless communication system. The method includes estimating channels associated with a plurality of transmit ports for each receive port from a plurality of receiver ports. Further, the method includes selecting the plurality of optimal transmit and receive beam pairs using average power level computation and capacity maximization techniques.
