Abstract

The present disclosure provides a method in a UE for feeding back channel state information (CSI) and the UE. The method comprises: acquiring a set of CSI processes which are configured by a transmission point (TP) to participate in multi-antenna multi-TP coordination; acquiring a sub-band (SB) inheritance which is configured by a TP for a CSI process from the set of CSI processes; calculating the CSI based on the configuration for the CSI process; and feeding the calculated CSI back to a TP. The present disclosure has the advantages of simple implementation and low signalling overhead and is applicable to enhanced 4G systems and to 5G systems.
