Method and system for constructing channel quality indicator tables for feedback in a communication system

摘要

Aspects of a method and system for constructing channel quality indicator tables for feedback in a communication system are provided. A user terminal may receive a signal transmitted by using a modulation and coding scheme (MCS) from a base station. The user terminal may assess channel quality information by accessing a CQI table to identify a CQI value based on the received radio signal. The CQI table may comprise various modulation regions in terms of spectral efficiency. The identified CQI value may be transmitted to the base station. Various standard system protocols such 3GPP, 3GPP LTE, or WiMAX, may be used for transmissions. The CQI table may be generated via PER versus spectral efficiency and/or SNR, respectively. The base station may select a MCS based on the CQI feedback from the user terminal for transmitting a subsequent radio signal to the user terminal.
