Abstract: Systems, methods, apparatuses, and computer program products for positioning support are provided. One method may include receiving, by a UE configured with power saving feature(s), positioning performance requirements for a positioning session. The method may also include estimating an impact of one or more power saving or reduced capability features on positioning measurements associated with the positioning session and, based on the accuracy and latency requirements and the estimated impact, determining the power saving or reduced capability features that the UE can implement while still achieving the accuracy and latency requirements for the positioning session. The method may then include signaling, to a network node, information on the determined power saving or reduced capability features that the UE can implement while still achieving the required accuracy and latency requirements for the positioning session.

Abstract: A method, apparatus, and a computer-readable storage medium for a virtual multi-transmission reception point (TRP) or multi-panel transmission for ultra reliable low-latency communications (URLLC) are provided. In one example implementation, the method may include receiving, by a network node, at least two channel state information (CSI) reports from a user equipment (UE), the at least two CSI reports are received based at least on transmission and/or reception configuration transmitted to the UE and determining, by the network node, at least two beams for downlink transmission based on the at least two CSI reports. The method may further include transmitting, by the network node, a physical downlink control channel (PDCCH) to the UE, the PDCCH carrying scheduling information based on the at least two CSI reports and transmitting, by the network node, a physical downlink shared channel (PDSCH) to the UE, the PDSCH carrying at least two duplicate downlink data transmissions, each of the at least two duplicate downlink data transmissions is associated with one beam of the at least two beams.
