APPARATUS AND METHOD FOR RECEIVING PACKET DATA ON A SUBSET OF CARRIER FREQUENCIES IN A WIRELESS COMMUNICATION SYSTEM

摘要

A wireless communication system includes base station (104) and remote station (102). The base station sends pilots on the allocated set of frequencies. The remote station estimates the channel and reports it back to the base station. Further, the base station selects a subset of the allocate frequencies to transmit in parallel packet data's to the remote station. Each packet data is proceeded by a header field for identifying the remote station. At the same time the base station sends pilots in the frequencies other than the subset selected. The remote station receives the packet data and the pilots, repeats back the channels corresponding to the pilots so that the transmitter can frequency hop to new frequency channels which have been estimated.
