Prior Publication US 2023/0283327 A1, Sep. 7, 2023
1. A wireless transceiver station with a plurality of antennas configured to create a plurality of concurrent and independent orthogonal frequency-division multiplexing (“OFDM”) wireless links between the wireless transceiver station and a plurality of user devices within a same frequency band, the wireless links formed over multipath downlink or uplink channels;
wherein the wireless transceiver station is configured to exploit channel reciprocity by estimating an uplink channel state information (CSI) between the plurality of antennas on the wireless transceiver station and one or more of the antennas of the plurality of user devices and using it to derive a downlink CSI between the plurality of antennas on the wireless transceiver station and one or more of the antennas of the plurality of user devices;
wherein the wireless transceiver station is configured to utilize the downlink CSI to precode a number of the plurality of concurrent and independent OFDM wireless links equal to more than ten times a number of at least one user device's antennas configured to communicate over at least one of the uplink channels of the concurrent and independent OFDM wireless links.
