Abstract
A method and system for dynamic rate switching via medium access channel layer signaling is disclosed, wherein data rates for high data rate channels are automatically shifted up or down based on a predetermined metric. In a preferred embodiment, data rates are automatically shifted up or down based on transmit channel gain required to maintain a required signal to noise ratio.
Claims7
A method for scheduling a plurality of mobile units for data transmission, the method comprising the steps of:
- determining a plurality of mobile units that require data transmission;
- determine power control feedback information for each mobile unit within the plurality of mobile units that require data transmission;
- and
- schedule the plurality of mobile units for data transmission based on their power control feedback information.
1 more element
An apparatus for scheduling mobile units for data transmission, the apparatus comprising:
- a channel statistic estimator, wherein the channel statistic estimator has power control information for a plurality of mobile units as an input and outputs a power-control statistic based on the power control information;
- a scheduler having the power-control statistic as an input and outputting scheduled mobile units based on the power control statistic.
