1. 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.
