Abstract:
1. A method of feeding back received signal quality information, the method comprising: receiving, at a receiver, a multiplexed signal including two or more signal streams; calculating, at the receiver, a received signal quality for the multiplexed signal as a function of two or more different stream-specific received signal qualities determined for the multiplexed signal; determining, at the receiver, a loss parameter that represents a loss in the received signal quality for the multiplexed signal arising from the two or more different stream-specific received signal qualities, wherein the determined loss parameter is useable to compensate the calculated received signal quality for the loss; generating, at the receiver, received signal quality information including the calculated received signal quality, or a quantized version thereof, and the loss parameter; and transmitting, from the receiver, the received signal quality information as feedback, wherein determining the loss parameter comprises expressing effective losses in the received signal quality arising from the two or more different stream-specific received signal qualities as loss functions of multiplexed signal coding rate and generating the loss parameter as a set of parameters corresponding to a best-fitting one of the loss functions.
