Abstract: Embodiments disclosed relate to apparatuses, systems, and methods for improved handling of phase noise (PN) in millimeter wave (MMW or mmWave) communications in a wireless communication system, such as 5G NR. When severe phase noise is present in a communication link, the link performance can be substantially degraded. Thus, it would be desirable to utilize techniques to compensate for phase noise in mmWave communications. In Rel-15, a Phase Tracking Reference Signal (PT-RS or PTRS) was specified for both downlink and uplink communications, specifically for Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM) and Discrete Fourier Transform spread Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). However, prior art approaches to PTRS using block-based pilot allocation schemes required complicated receiver processing. Thus, the techniques disclosed herein attempt to embed one or multiple bands with DFT-S-OFDM PTRS design in the data allocation bandwidth of an OFDM transmission to improve handling of PN at sub-OFDM symbol time intervals.

Abstract: Apparatuses, systems, and methods for synchronization and resource allocation for sidelink positioning, e.g., in 5G NR systems and beyond. A device, e.g., a UE or an LMF, may be configured to transmit, to a plurality of wireless devices, an anchor selection request for a sidelink positioning procedure for a target UE. The device may be configured to receive, from one or more wireless devices of the plurality of wireless devices, an anchor selection response. The device may be configured to select based, at least in part, on the anchor selection responses, one or more anchor devices from the one or more wireless devices.

Abstract: Methods, systems, apparatuses, and computer programs for search space configuration for multi-slot physical downlink control channel (PDCCH) monitoring. In one aspect, a method can include actions of obtaining, by a base station, data indicating capabilities of user equipment (UE), wherein the obtained data includes at least data indicating sub-carrier spacing used by the UE, determining, by the base station and based on the obtained data indicating capabilities of the UE, (i) a periodicity selection parameter that indicates a subset of slot periodicities that the UE is to monitor for PDCCH and (ii) one or more other search space configuration parameters. generating, by the base station, a UE configuration command for configuring the search space that includes at least the determined periodicity selection parameter, encoding, by the base station, the generated UE configuration command for transmission to the UE, and transmitting, by the base station, the encoded command to the UE.

Abstract: A user equipment (UE), a baseband processor or other network device can operate in a new radio (NR) unlicensed network to correlate resource selection with shared spectrum channel access. The device can perform a resource selection procedures within a resource selection window (RSW) to determine a set of candidate resources, and a clear channel assessment (CCA). A resource selection of one or more resources can be performed from the set of candidate resources to enable a sidelink (SL) communication. The CCA initiates after an aperiodic traffic arrival, after a previous transmission, or after the resource selection is completed.

Abstract: This disclosure relates to techniques for configuring 8 transmit antenna uplink operation in a wireless communication system. A wireless device and a cellular base station may establish a wireless link. The wireless device may perform sounding reference signal transmissions on each of 8 sounding reference signal resources, where each resource is associated with a transmit antenna port. The wireless device may receive an indication from the cellular base station of an 8 transmit antenna port uplink configuration to use, which may include a sounding reference signal resource indicator. The wireless device may perform uplink communication with the cellular base station using the 8 transmit antenna port configuration.
