APPARATUS AND METHOD FOR BROADCAST SUPERPOSITION AND CANCELLATION IN A MULTI-CARRIER WIRELESS NETWORK

摘要

A base station for use in an orthogonal frequency division multiplexing (OFDM) wireless network capable of communicating with a plurality of subscriber stations in a coverage area of the OFDM wireless network. The base station transmits a first OFDM symbol in a first time slot, wherein the first OFDM symbol comprises a first plurality of subcarriers in which broadcast data directed to a first plurality of subscriber stations is superimposed on unicast data directed to at least one selected subscriber station.
