METHOD FOR PERFORMING WIRELESS SWITCHING

摘要

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 that receives a plurality of orthogonal frequency division multiplexing (OFDM) signals on a first carrier frequency of a downlink. Each of the plurality of OFDM signals includes carrier frequency assignment information indicating a carrier frequency to transmit uplink data and spatial pattern information indicating a spatial pattern. In response to the carrier frequency assignment information of each of the plurality of OFDM signals, a transmitter and the controller of the wireless user terminal transmit a plurality of uplink signals. Each of the plurality of uplink signals are transmitted on the indicated carrier frequency and using the indicated spatial pattern.
