摘要:
A system and method are provided for intelligently incorporating a mmWave communication link in a heterogeneous cellular/Wi-Fi networking environment. The combination improves overall data transmission capacity of the heterogeneous networking environment, and also provides superior user Quality of Experience. The combination of the mmWave communication link with the cellular/Wi-Fi communication system is integrated in a synergistic manner that allows each of the individual communication technologies to complement the other. Using highly-directional beamforming antennas the mmWave communication link provides wide area network coverage by deploying a plurality of directional beams in sectors to complement the coverage area of the wide area network systems operating in other frequency bands.

A multiple-input multiple output (MIMO) receiver includes circuitry to receive a MIMO transmission through a plurality of antennas over a channel comprising two or more 20 MHz portions of bandwidth. The MIMO transmission comprises a plurality of streams, each transmitted over a corresponding spatial channel and configured for reception by multiple user stations. The MIMO receiver also includes circuitry to simultaneously accumulate signal information within at least two or more of the 20 MHz portions of bandwidth. Each 20 MHz portion comprises a plurality of OFDM subcarriers. The MIMO receiver also includes circuitry to demodulate at least one of the steams using receive beamforming techniques. In this way, multi-user protocol data units can be received.
