TECHNIQUES TO CONTROL POWER BY CONTROLLING AGREGGATE TRAFFIC IN A CHANNEL
First Claim
1. A method for controlling power transmitted in a channel for wireless communications, the method comprising:
- determining an estimate of a power level being used in the channel for wireless communications;
determining if additional power in the channel can be allotted to one or more transmitters based on the estimate power level and an aggregate allowed power level; and
if more power can be allotted, sending a signal to the one or more transmitters indicating that the transmitter may use additional power to transmit data in the channel.

Abstract
Particular embodiments provide techniques for controlling power in a channel. The power being consumed in a channel may not always be fully used. For example, bursty or Aloha traffic may limit the power being used to transmit data in a channel. Thus, particular embodiments allow transceivers to increase the power used to transmit data in a channel. For example, many transceivers may be allowed to send data in a channel. If all transceivers were transmitting at once at an increased power level, the aggregate power level may be exceeded for the channel. All the transceivers may be allotted a fixed percentage of the aggregate power so as to guarantee not exceeding the power limit. However, not all transceivers may be using their allotted power at the same time. Thus, when the allotted aggregate power in the channel is not fully utilized, a transceiver may increase its traffic beyond its normal portion. For example, the transceiver may use a power-demanding high order modulation scheme to send data.

9. A method for controlling power transmitted in a channel at a transmitter for wireless communications, the method comprising:
-
determining that additional power may be used to transmit data in the channel based on an estimate of a power level being used in the channel and an aggregate allowed power level, wherein a transmitter is configured to transmit power at a first power level; receiving data traffic at the transmitter for the wireless communications; and increasing power used in transmitting the received traffic to a second power level above the first power level, wherein the aggregate allowed power level can be exceeded if a number of additional transmitters transmit at the second power level in the channel simultaneously with the transmitter. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. An apparatus configured to control power transmitted in a channel for wireless communications, the apparatus comprising:
-
logic, when executed by a processor, that is operable to; determine an estimate of a power level being used in the channel for wireless communications; determine if additional power in the channel can be allotted to one or more transmitters based on the estimate power level and an aggregate allowed power level; and send a signal to the one or more transmitters indicating that the transmitter may use additional power to transmit data in the channel if more power can be allotted.
