Patent ID: 7002899

Claim:
A process comprising the steps of: (1) determining in any way that a particular remote transmitter or cable modem in a distributed code division multiplexed or orthogonal frequency division multiplexed or other digital data communication system in which individual remote transmitters or cable modems simultaneously transmit on a plurality of logical channels has a headroom problem; and (2) resolving the problem in any way by restricting the number of spreading codes in the case of a code division multiplexed system or the number of frequency carriers in the case of an orthogonal frequency division multiplexed system that are allocated to any remote transceiver that has a headroom problem for use in transmitting a burst, said restricted number being a number which will cause the total transmit power of the remote transmitter or cable modem to be divided among fewer spreading codes or fewer carriers or fewer logical channels so as to transmit on each spreading code or carrier or logical channel simultaneously with sufficient power to overcome said headroom problem.
