Abstract:
Apparatus and methods are provided multiple transmission. In one novel aspect, TCI-state indication for non-coherent joint transmission (NCJT) channel station information (CSI) reporting is provided. The UE receives NCJT from at least a first transmission from a first transmission point (TRP) and a second transmission from a second TRP, determines a receiving (RX) spatial filter information for the NCJT and acquires channel state information (CSI) according to a report setting based on the determined RX spatial filter to simultaneously acquire at least two channel measurement resources (CMRs) and one interference measurement resource (IMR), wherein at least one CMR is from the first TRP and at least one CMR is from the second TRP. In one embodiment, the RX spatial filter information is determined based on a group-based beam reporting procedure performed by the UE. In another embodiment, the RX spatial filter information is determined based on TCI-state received from the wireless network.
