Method and system for a greedy user group selection with range reduction in TDD multiuser MIMO downlink transmission

摘要

Certain aspects of a method and system for processing signals in a communication system may include maximizing system capacity for a time division duplex (TDD) multiuser multiple-input multiple-output (MIMO) downlink system, based on a single signal for a single user within a reduced search range or the single signal for the single user and at least one other signal for one other user within a remaining portion of the reduced search range. The reduced search range may be generated by sorting a plurality of signals based on a channel gain corresponding to each of the plurality of signals. The single signal for the single user may be selected from the reduced search range corresponding to a channel gain that is greater than a channel gain corresponding to a remaining portion of the reduced search range.
