Abstract:
1. A method for selecting mobile station candidates for use with virtual multiple-input multiple-output (“V-MIMO”) in a communication system, the communication system including at least one base station and a plurality of mobile stations, the method comprising: sending, by the at least one base station, at least one signal to a first mobile station of the plurality of mobile stations; receiving, by the at least one base station, a report from the first mobile station, wherein the report includes a downlink metric measured by the first mobile station; estimating a downlink geometry for the first mobile station based on at least the downlink metric; estimating an average transmit power spectral density for the first mobile station; determining, dependent upon the downlink geometry and the average transmit power spectral density, eligibility of the first mobile station for uplink V-MIMO candidate list selection, wherein said determining comprises determining that the average transmit power spectral density is less than a first predetermined threshold and that the downlink geometry is greater than a second predetermined threshold; responsive to determining the first mobile station is eligible for uplink V-MIMO candidate list selection, pairing the first mobile station with a second mobile station also determined to be eligible for uplink V-MIMO candidate list selection.
