Abstract

A wireless communication system includes an infrastructure device for transmitting and receiving communications to and from a plurality of user terminals. Each user terminal includes a receiver and a controller that receives a first orthogonal frequency division multiplexing (OFDM) signal on a first carrier frequency that has assignment information indicating a second carrier frequency to transmit uplink data and beam forming information. In response to the assignment information, a transmitter of the user terminal transmits a second OFDM signal on the second carrier frequency using a beam indicated in the beam forming information.
