Abstract
According to an embodiment of the invention, a method and apparatus are described to receive a signal, determine a quality of the received signal, and transmit a power control message, with a selected size, the power control message being based at least in part on the quality of the received signal. The power control message requests a modification in transmission power or indicates the deviation of the signal quality from a reference signal quality.
Claims86
A method comprising:
- receiving a signal;
- determining a quality of the received signal, the quality of the signal being compared to a reference quality;
- and
- transmitting a power control message, with a selected size, the power control message being based at least in part on the quality of the received signal;
- the power control message including a request for a modification in transmission power for a power control message transmitted by a first device and including an indication of a deviation of the quality of the received signal from the reference quality for a power control message transmitted by a second device.
2 more elements
A method comprising:
- transmitting a signal;
- receiving a power control message, of a selected size, the power control message being based at least in part on a quality of the signal;
- and
- adjusting transmission power based at least in part on the received power control message;
- the power control message including a request for a modification in transmission power for a power control message received by a second device, and including an indication that the transmitted signal deviates from a reference signal quality for a power control message rceived by a first device.
2 more elements
A method comprising:
- transmitting a signal, the signal including:
- an optional extended power control message, the extended power control message including a request that the transmission power level be increased or decreased by an amount specified by the extended power control message if the signal is sent by a first device and includes an indication that a signal quality is above or below a target signal quality by an amount specified by the extended power control message if the signal is sent by a second device;
- and
- a standard power control message, the standard power control message if the extended power control message is not included in the signal, including a request that a transmission power level be increased or decreased by a predetermined amount if the signal is sent by the first device and includes an indication that the signal quality is above or below the target signal quality by a predetermined amount if the signal is sent by the second device.

A radio unit comprising:
- a receiver to receive a first signal, the radio unit determining a quality of the first signal;
- and
- a transmitter to transmit a second signal, the second signal including a power control message of selectable size related to a modification in transmission power, the power control message being based at least in part on the quality of the first signal, the power control message including a request for a modification in transmission power if the radio unit is a first type of radio and the power control unit including an indication of a deviation of the quality of the first sianal from a reference signal quality if the radio unit is a second type of radio.
A radio unit comprising:
- a transmitter to transmit a first signal;
- and
- a receiver to receive a second signal, the second signal including a power control message of selectable size, the power control message being based at least in part on a quality of the first signal in comparison with a reference quality, the radio unit adjusting transmission power of the transmitter in response to the power control message;
- the power control message including a request for a modification in transmission power if the radio unit is a first type of radio and the power control message including an indication of a deviation of the quality of the first siunal from the reference quality if the radio unit is a second type of radio.
