Abstract

A system and method for broadband multi-carrier communications. The system includes a base station, user equipment, and a transmission scheme manager. The base station transmits a downlink reference signal. The user equipment receives the downlink reference signal and acquires channel status information from the downlink reference signal for at least one available frequency band within a downlink frequency band. The transmission scheme manager is coupled to the base station and allocates a radio resource to the user equipment based on channel status feedback from the user equipment. The channel status feedback is at least partially based on the channel status information.
