Abstract

A remote station for a wireless communication system including a base station is disclosed. The remote station includes a front end structure configured to receive packet data in parallel on a subset of carrier frequencies. Each packet data is preceded by a header field for identifying the remote station as the recipient of the packet data and the subset of carrier frequencies is based on a set of a corresponding number of multiple carrier frequencies.

Claims
