Abstract
An efficient return channel spectrum utilization technique for communication systems supporting adaptive spread spectrum. Requests for bandwidth allocation using a spread factor are analyzed to determine if there are any channels capable of supporting the spread factor. The request is acknowledged if at least one channel is capable of supporting the request. Adjacent channels required to accommodate the requested spread factor are reserved, and additional bandwidth requests are allocated on non-reserved channels.
Claims18
A method comprising:
- determining a list of tuples corresponding to channels above and below a selected channel that are usable for applying spread factors to the selected channel;
- receiving a request, from a terminal, for bandwidth allocation using a requested spread factor;
- determining if any channels are currently capable of supporting the requested spread factor;
- rejecting the request if no channels are currently capable of supporting the requested spread factor;
- generating an acknowledgement and transmitting the acknowledgment to the terminal if at least one channel is capable of supporting the request;
- reserving two or more channels adjacent to the selected channel from the at least one channel based, at least in part, on the requested spread factor;
- and
- allocating bandwidth for data received from other terminals on non-reserved channels.

An apparatus comprising:
- a transceiver for transmitting and receiving information;
- and one or more processors configured to:
- determine a list of tuples corresponding to channels above and below a selected channel that are usable for applying spread factors to the selected channel;
- receive a request, from a terminal, for bandwidth allocation using a requested spread factor;
- determine if any channels are currently capable of supporting the requested spread factor;
- reject the request if no channels are currently capable of supporting the requested spread factor;
- generate an acknowledgement and control the apparatus to transmit the acknowledgment to the terminal if at least one channel is capable of supporting the request;
- reserve two or more channels adjacent to the selected channel from the at least one channel based, at least in part, on the requested spread factor;
- and allocate bandwidth for data received from other terminals on non-reserved channels.
