MEASUREMENT METHOD FOR CHANNEL STATE INFORMATION, USER EQUIPMENT AND BASE STATION

摘要

Embodiments of the present invention provide a measurement method for channel state information, user equipment and a base station. The measurement method includes: 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. With the embodiments of the present invention, channel state information feedback configuration is performed to each cell or transmission point participated in coordination, and a unified structural design for feedback information may be used, so that channel feedback information for multiple transmission points or multiple cells can serve for not only transmission of a single cell, but also transmission of multiple cells.

1. A measurement method for channel state information, applicable to a base station in a coordinated multipoint system, the measurement method comprising:
a coordinated point selecting process for selecting, by the base station for user equipment, one or more coordinated transmission points for coordinated multipoint transmission; and a measurement subset configuring process for independently configuring independent time domain restriction 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 independent time domain restriction.
