Apparatus and method for multiplexing broadcast and unicast traffic 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 is capable of transmitting a first OFDM symbol in a first time slot, wherein the first OFDM symbol comprises a first plurality of subcarriers used to transmit broadcast data directed to a plurality of subscriber stations and a second plurality of subcarriers used to transmit unicast data directed to at least one selected subscriber station.
