Abstract: An evolved Node B (eNB) and method for coherent coordinated multipoint transmission with per CSI-RS feedback are generally described herein. The eNB may configure a first cooperating point and a second cooperating point to jointly transmit a multi-node channel-state information (CSI) reference signal (RS) (CSI-RS) in predetermined resource elements of a resource block. The eNB may receive CSI reports as feedback from user equipment (UE). The CSI reports may include a precoding matrix indicator (PMI) indicating relative phase information between the cooperating points based on the multi-node CSI-RS. The CSI reports for the multi-node CSI-RS may be restricted to a PMI of rank-1. The eNB may configure the cooperating points for a coherent joint transmission to the UE based at least on the relative phase information. The coherent joint transmission may also be jointly beamformed based on single-node PMIs.

Abstract: An apparatus and system of enabling reference signal measurements in a non-terrestrial network (NTN) system are described. The UE provides capability information that indicates a maximum number of synchronization signal block (SSB)-based measurement timing configurations (SMTCs) simultaneously supported by the UE for measurement of reference signals from cells in the NTN system and receives SMTCs based on the capability information and a real time estimate of timing differences among the cells. The UE sends/receives data based on the SMTCs and whether the UE supports simultaneous data communication and measurement. Broadcast system information contains a flag that indicates which of dynamic and semi-static configuration is used, the maximum SMTC's dependent on the flag value. Radio resource control (RRC) signalling is used to send sets of SMTCs that have different offsets. Different sets are activated using dynamic signaling according to real time estimates of the timing differences.
