METHOD AND SYSTEM FOR CONSTRUCTING CHANNEL QUALITY INDICATOR TABLES FOR FEEDBACK IN A COMMUNICATION SYSTEM

摘要

side of the channel quality indicator table construction method and system for feedback from the communication system are provided. User terminal can receive the transmitted signal using modulation and coding schemes (modulation and coding scheme, MCS) to the base station. The user terminal may access the channel quality information by accessing a CQI table to identify a CQI value based on the received wireless signal. There CQI table may comprise various modulation regions in terms of spectral efficiency (spectral efficiency). The identified CQI value may be transmitted to the base station. 3GPP, 3GPP LTE, or various standard system protocols such as WiMAX can be used for the transmission. CQI table may be generated via PER for each of the spectral efficiency and / or SNR. The base station may select an MCS based on the CQI feedback from the user terminal to transmit a subsequent radio signal to the user terminal.
