CHANNEL STATE INFORMATION FEEDBACKS FOR COORDINATED MULTIPOINT TRANSMISSIONS

摘要

A method and a User Equipment (UE) for used in a Coordinated Multiple (CoMP) transmission are disclosed. The method for example comprises: acquiring a Channel State Information (CSI) feedback for each of at least one non-zero-power Channel State Information Reference Signal (CSI-RS) resource respectively, and providing, to a network side, at least one CSI feedback so as to facilitate a coordination of Downlink (DL) transmissions in the DL CoMP transmission at the network side. By doing so, a new Channel State Information (CSI) feedback reporting mode is introduced, so as to provide to a network side a plurality of CSI feedbacks based on which a better coordination of DL transmissions in the CoMP transmission can be achieved.
