METHOD FOR TRANSMITTING CHANNEL QUALITY INFORMATION, USER EQUIPMENT, METHOD FOR TRANSMITTING MULTI-USER DATA, AND BASE STATION

摘要

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and apparatus which indicate, using multiple CQIs, channel quality in the event multiple users are scheduled in the same time/frequency domain, and to a method and apparatus which estimate a channel state using said multiple CQIs. According to embodiments of the present invention, a channel state can be estimated in a more accurate manner in a multi-user MIMO system.
