METHOD, USER DEVICE AND BASE STATION FOR MEASURING CHANNEL STATE INFORMATION Russian patent published in 2016 - IPC H04W24/00 

FIELD: communication.

SUBSTANCE: invention relates to mobile communication. Measurement method comprises: selecting one or more coordinated transmission points for coordinated multipoint transmission by the base station for user equipment; and independently configuring a measurement subset used for channel state information feedback for each base station and each coordinated transmission point, so that the user equipment performs measurement according to the measurement subset.

EFFECT: technical result consists in using channel feedback information for multiple transmission points or multiple cells for transmission by channel state information feedback configuration information for each cell or transmission point participated in the coordination, thus, unified structural design for feedback information may be used.
