Abstract
In one embodiment, a method includes detecting a power level of a power amplifier coupled to a transceiver during a current burst of a radio communication and providing the detected power level from the power amplifier to the transceiver and controlling a power level of the power amplifier during a next burst based on the detected power level of the current burst.
Claims26
A method comprising:
- receiving a detected power level of a power amplifier during a current burst of a radio communication from a mobile station;
- and
- controlling a power level of the power amplifier during a next burst of the radio communication based on the detected power level of the current burst.
A transceiver comprising:
- an interface to receive transmit power control information from a processor;
- a memory to store first parameter information for a first burst of a data transmission from the transceiver;
- and
- a controller coupled to the interface and the memory to receive the transmit power control information and the first parameter information and to determine second parameter information for a second burst of the data transmission based on the first parameter information and the transmit power control information, the second burst following the first burst.

An article comprising a machine-readable medium including instructions that enable a system to:
- receive a detected power level of a first burst of a multi-slot burst communication from a power amplifier (PA);
- determine a power level update for a second burst of the multi-slot burst communication based at least in part on the detected power level of the first burst;
- and
- provide the second burst to the PA responsive to the power level update.
1 more element
A system comprising:
- a transceiver having an interface to receive power control information from a processor, and a controller coupled to the interface to determine a power control update for a succeeding burst of a multi-slot burst communication based on the power control information and feedback information from a preceding burst of the multi-slot burst communication, the controller to determine the power control update during the preceding burst and to apply the power control update during an inter-burst period between the preceding burst and the succeeding burst;
- a power amplifier coupled to the transceiver to provide the feedback information;
- and
- an antenna coupled to the power amplifier to transmit the multi-slot burst communication.
