Power Division Multiple Access

摘要

A satellite communication system includes a hub and one or more terminals, wherein the one or more terminals may be configured to communicate over a satellite with the hub using a segment of the satellite's resources and using a single channel per carrier (SCPC) access scheme. Methods are presented herein for facilitating the dimensioning of at least a power characteristic of said space segment using a Demand Assignment Multiple Access approach and for enforcing the dimensioned power characteristic in real-time, or substantially in real-time. Also presented are methods for allocating power to SCPC carriers, wherein a maximum power level for a carrier may be determined using a DAMA technique.

主权项

1. A terminal configured to:
receive, from a hub within a satellite communication system, allocation information corresponding to a channel for transmitting a carrier; receive, from the hub, a maximum reception level at which the carrier is allowed to be received at the hub; receive, from the hub, one or more reception level measurements corresponding to the carrier; and regulate a power level at which the terminal transmits the carrier at least in accordance with:
at least one of the one or more reception level measurements received from the hub; the maximum reception level at which the carrier is allowed to be received at the hub; and a data rate of data to be transmitted by the terminal.
