Patent ID: 8503342

Claim:
A transmitter comprising: a memory for storing a first data that is to be transmitted, and a second data that has been transmitted; a processor for receiving requests to re-transmit the second data from the memory; a monitor for receiving, from user equipment, power control commands indicating a change in power to maintain, at a predetermined level, a power of a transmission link between the transmitter and a receiver associated with the user equipment and for separately summing a number of power control commands indicating that an increase in power is necessary and a number of power control commands indicating that a reduction in power is necessary over a predetermined period of time; a power control unit electrically connected to the monitor, and configured to: control the power of the transmission link such that the power is temporarily higher than the pre-determined level; and maintain the power of the transmission link at a previous level after receiving a power control command from the user equipment that requests a reduction in power; and a data control unit configured to schedule the second data for re-transmission in periods when the power of the transmission link is higher than the pre-determined level based at least in part on a difference in sums.
