METHODS FOR APERIODIC CSI REPORT TRIGGERING FOR FLEXIBLE SUBFRAMES IN LTE TDD EIMTA SYSTEMS WITH DYNAMIC UL-DL RECONFIGURATION

摘要

A method to trigger aperiodic CSI reports in LTE TDD systems having dynamic uplink-downlink configurations is proposed. When uplink grants can be sent on any subframe, the method further defines how to indicate which measured subframe set is to be used in reporting the aperiodic CSI. The method is useful for homogeneous networks and networks employing enhanced interference management and traffic adaptation (eIMTA).
