Abstract:
Described herein is a channel state information (CSI) calculation method for non-coherent joint transmission by using a dependency between CSI reported for each CSI. In one embodiment, configuration of CSI reporting is such that CSI calculated for one CSI process (denoted as the reference CSI process) can be used for interference calculation for another CSI process (denoted as the dependent CSI process).
