HIGHER-RANK FEEDBACK METHODS AND DEVICES FOR SINGLE USER BASED JOINT TRANSMISSION

摘要

Embodiments of the present invention provide a method for processing fed-back channel information in an eNB, comprising: receiving, from a user equipment, polarization direction and power imbalance information of each cell so as to obtain long-term and wideband fed-back channel information; receiving, from the user equipment, both amplitude difference and phase difference between different polarization directions of a same cell and amplitude difference and phase difference between different cells, so as to obtain short-term and subband fed-back channel information; and combining into a complete channel based upon the long-term and wideband fed-back channel information and the short-term and subband fed-back channel information.
