Abstract: Wireless positioning accuracy of a user equipment (UE) is impacted by locations of the transmit/receive points (TRPs) and UE for wireless positioning. To improve the accuracy of estimated locations, a geometric dilution of precision (GDOP) may be determined for different groups of candidate TRPs, with the GDOP indicating a potential positioning error associated with the group of candidate TRPs. A UE may determine GDOPs for different combinations of candidate TRPs. One or more devices of a wireless network (e.g., a location server and/or a UE for positioning) may select or exclude one or more candidate TRPs from being used for wireless positioning of a UE based on the determined GDOPs. Exclusion or selection of candidate TRPs for wireless positioning may also be based on quality measurements of PRSs (such as an RSRP or SNR) or a time duration associated with measuring the PRSs from the candidate TRPs to be selected.

Abstract: Aspects are provided which allow a first device to secure transmission of polar encoded control information by encoding at least a portion of frozen bits and/or information bits with a shared key with a second device before these bits are encoded by a polar encoder. The first device determines whether to encode at least one of a plurality of frozen bits or a plurality of information bits using the shared key. Based on the determination, the first device encodes the frozen bits and/or the information bits, and sends the encoded frozen bits and/or the encoded information bits to the second device. Since the receiving device has the shared key, the receiving device may successfully decode the control information, while an eavesdropper who receives the encoded bits may fail to decode the control information due to lack of knowledge of the shared key.

Abstract: Aspects are provided allowing a UE to perform early termination of repetitions of an ongoing PUSCH transmission in response to a DCI from a base station indicating whether a prior PUSCH transmission or repetition was successfully decoded. The UE obtains information configuring an uplink data transmission and a repetition of the uplink data transmission. The UE sends the uplink data transmission to a base station. The UE terminates the repetition of the uplink data transmission in response to reception of downlink information in a downlink control channel. Thus, UE power reduction and enhanced resource efficiency may be achieved. Moreover, the repetition is terminated after a time gap following a CORESET where the downlink control channel is received. As a result, a start time for terminating PUSCH repetitions may be configured to accommodate various timing considerations such as dynamic TDD, different numerologies between PDCCH and PUSCH, and multiple PUSCH processing capabilities.
