Patent ID: 7627336

Claim:
A transmission unit, comprising: a first unit receiving scheduled first data for transmission on at least a first channel: a power control unit for the first channel responsive to a respective closed loop power regulation signal under which at least the transmit power rate of change is limited to a predetermined value per time unit; a packet data scheduler scheduling second data packets for transmission on at least a second channel at an actual power level; and, a power amplifier amplifying and outputting the scheduled first and second data, wherein the outputted first and second channels are subject to interference from one another, and wherein the packet data scheduler is operative to: receive the first scheduled data; determine a possible power at a given instance as the maximum value of either the actual power at a previous instance or the possible power determined at a previous instance, decreasing the maximum value by a predetermined value (d); and, determine a permitted power at a given instance as the maximum value of either the actual power of a previous instance added with the predetermined value (d) or the determined possible power.
