CHANNEL QUALITY INFORMATION REPORTING METHOD, BASE STATION, AND USER TERMINAL

摘要

A channel quality information reporting method for reporting channel quality information from a user terminal to a base station comprises: a format determination step in which the base station determines a channel quality information format based on information from the user terminal; a format transmission step in which the base station transmits the determined channel quality information format to the user terminal; and a channel quality information generation step in which the user terminal generates channel quality information based on the received channel quality information format. The base station may determine the channel quality information format based on a required data rate. The base station may also determine the channel quality information format based on a delay spread. The base station may also determine the channel quality information format based on a moving speed.
