Abstract: A wireless communication system includes an infrastructure device for transmitting and receiving communications to and from a plurality of wireless user terminals. Each wireless user terminal includes a receiver and a controller configured to receive a plurality of orthogonal frequency division multiplexing (OFDM) signals on at least one downlink carrier frequency. Each of the plurality of OFDM signals includes assignment information. The receiver is configured to receive a plurality of downlink signals each responsive to a respective OFDM signal of the plurality of OFDM signals such that each downlink signal is received on a downlink carrier frequency and using a downlink spatial pattern. Further, the controller is configured to dynamically change the downlink carrier frequency of the receiver for receiving the plurality of downlink signals based on the plurality of OFDM signals, wherein the plurality of downlink signals have different spatial patterns.
