The active antenna array system is configured to perform the transmitting of the reference signals using multiple vertical beams having vertical patterns designed to provide desired vertical patterns after codebook feedback from a codebook is applied on transmissions from logical ports of the antenna array.

Estimating and utilizing client receive interference cancellation capability in multi-user transmissions


A first device having a plurality of antennas wirelessly transmits multiple series of test packets to a second device having one or more antennas, each series of test packets being transmitted with a different level of interference imposed on the test packets. The first device determines a packet error rate for each series of test packets transmitted by the first device.
