METHOD, USER DEVICE AND BASE STATION FOR MEASURING CHANNEL STATE INFORMATION

摘要

A method, user device and base station for measuring channel state information are provided by the embodiments of the present invention. The measurement method comprises the following steps: the base station selects one or more coordinated transmission point to perform coordinated multiple points transmission for the user device; every base station and coordinated transmission point is independently configured a measurement subset for feeding back a channel state information, so that the user device performs measurement according to the measurement subset. By using the embodiments of the present invention, independent channel state information feedback configuration is performed to every cell and transmission point which participates in coordination, an uniform feedback information structure design can be used, so that the channel feedback information for multiple transmission points or multiple cells can serve transmission of a single cell, and can also serve transmission of multiple cells.
