Abstract
A SPREAD ALOHA Multiple Access (SAMA) channel uses distinct chip phases to label portions of a common SAMA channel and to reserve specific phases by means of a random access packet in the same SAMA channel. In the new SAMA reservation channel protocol, reservations consisting of the specification of a given chip phase are transmitted in a random access mode in a common SAMA channel. After a given user has reserved a given chip phase, that chip phase can be used on a reserved basis by that user to guarantee a certain quality of service. The reservation can be made by a user who simply initiates transmissions with a given chip phase and continues to use that chip phase if the user's first packet (the packet making the reservation) is received correctly. The SAMA hub broadcasts a list of reserved chip phases or broadcasts a list of free chip phases to ensure that other transmitters do not use the reserved chip phase. Alternately, the hub requires a transmitter to adjust chip phases of its transmitters.
