Transmission power control method
First Claim
1. A transmission power control method for a communication system comprising a transmitter and a plurality of receivers, the transmitter coupled to the plurality of receivers via a plurality of corresponding outgoing links, the transmission power control method comprising:
- the plurality of receivers replying a plurality of different first suggested transmission power back-off levels to the transmitter, wherein each of the plurality of receivers performs channel estimation for each of the plurality of corresponding outgoing links, and replies a respective first suggested transmission power back-off level to the transmitter; and
the transmitter collecting the plurality of different first suggested transmission power back-off levels from the plurality of receivers and determining a new transmission power back-off level according to all of the plurality of different first suggested transmission power back-off levels, wherein the new transmission power back-off level is the same for all continuing transmissions to all of the plurality of receivers;
wherein the new transmission power back-off level is the lowest transmission power back-off level among the plurality of different first suggested transmission power back-off levels.
