Abstract

Provided are a method for determining multi-user channel quality in a mobile communication system, a user terminal and a base station of the present invention. The method includes: in each user terminal, calculating the MU CQIs based on a first feedback template notified from a base station that has control over the user terminal or a second feedback template set by the user terminal and feeding the MU CQIs back to the base station. In the first feedback template or the second feedback template, a feedback ratio of MU CQIs for a plurality of hypothetical interference numbers k are defined, k being an integer larger than 0 and smaller than a maximum number of users schedulable by the base station. According to the present invention, it is possible to improve the accuracy in multi-user MIMO scheduling.
