First Claim
1. A method of communicating between first and second stations, including the steps of:
- providing at the first station a first preamble including first reverse link parameters and first forward link parameters individual to the first station and providing first data after the preamble, transmitting the first preamble and the first data from the first station to the second station in accordance with the first forward link parameters in the first preamble, receiving the first preamble and the first data at the second station and recovering the first data at the second station, providing a second preamble and second data at the second station, the second preamble at the second station including second forward link parameters in accordance with the first reverse link parameters received at the second station from the first station and including second reverse link parameters, and transmitting the second preamble including the second forward link parameters and second reverse link parameters and the second data from the second station to the first station.

Abstract
Each of first and second stations, in communicating with the other station, provides a preamble including forward link parameters and reverse link parameters. The forward link parameters in each preamble for each individual station are provided for each station in accordance with the reverse link parameters previously transmitted to the station in packets from the other station. The reverse link parameters in each preamble in each individual station provide an indication to the other station of the forward link parameters to be provided by the other station in the next transmission of a packet to the individual station from the other station. Data is provided in packets at each station to be transmitted to the other station. Each packet transmitted by each station to the other station includes a preamble and includes data after the preamble.
