A METHOD AND AN APPARATUS FOR PROVIDING CHANNEL QUALITY INFORMATION IN A WIRELESS COMMUNICATION SYSTEM

摘要

A method and an apparatus for providing channel quality information in a wireless communication system are disclosed. According to one embodiment of the invention, a method for transmitting channel quality information includes receiving a downlink signal, calculating a channel quality information index for the received downlink signal at least based on a number of resource elements for a physical downlink shared channel (PDSCH), wherein the number of resource elements for the PDSCH is determined at least based on an overhead of a demodulation reference signal (DMRS), and transmitting the calculated channel quality information index.
