CHANNEL QUALITY INDICATOR ACQUISITION METHOD, USER EQUIPMENT, AND EVOLVED NODE B AND SYSTEM

摘要

This application relates to a method for acquiring a channel quality indicator, a user equipment, an evolved node B and a system. The method includes: calculating subband channel quality indicators CQIs of at least two subbands, where there is an overlapped resource block between the subbands; and transmitting the subband CQIs to an evolved node B eNB. In the method for acquiring a channel quality indicator, the user equipment, the evolved node B and the system of the present application, there is an overlapped resource block between adjacent subbands, and meanwhile the channel quality of the resource block of the subband is obtained by using different subbands, thus the feedback accuracy of the channel quality of the resource block of each subband, especially the channel quality of the resource block in the subband overlapping area, thereby improving the granularity of frequency-selective scheduling, and improving the frequency-selective scheduling and the link adaptation, and therefore, the system throughput is increased.
