Method and apparatus reporting channel quality indicator of communication system

摘要

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.

1. A method reporting a channel quality indicator of a communication system, comprising:
detecting a first measurement reflecting a first communication quality of the communication system; providing a number of first references which respectively correspond to a number of indicator levels; providing the channel quality indicator according to the number of indicator levels and a relation between the first measurement and the number of first references; and updating at least one of the number of first references according to a second measurement which reflects a second communication quality of the communication system.
