A power adaptation apparatus for a wireless communication channel includes a power ratio compensator. The power ratio compensator is capable of receiving a channel quality indicator and compensating a power ratio parameter according to the channel quality indicator, wherein the power ratio parameter defines a relation between power of the wireless communication channel and power of another wireless communication channel, and is referenced for setting the power of the wireless communication channel.

Power adaptation apparatus and power adaptation method for controlling uplink/downlink power

The present invention provides a method and associated apparatus providing a signal metric for a transmitter of a communication system including: accumulating a plurality of power terms, each power term corresponding to a product of one of symbol amplitudes and one of scaling factors; and calculating the signal metric according to the accumulated power terms.

Method and apparatus providing signal metric for transmitter

The present invention provides a method and apparatus reporting a channel quality indicator (CQI) of a communication system, including: detecting a first measurement reflecting a first communication quality of the communication system, providing first reference(s) respectively corresponding to indicator level(s), providing CQI according to the indicator level(s) and a relation between the first measurement and the first reference(s), and updating one (or more) first reference according to a second measurement reflecting a second communication quality of the communication system. For example, the first measurement can represent signal to interference ratio or mutual information, and the second measurement can represent data error rate or throughput. First reference(s) can be further adjusted according to a third measurement, e.g., a power scheduling of base station, such that CQI can be updated if base station schedules additional transmission power.
