Abstract: A method includes causing, at a first user equipment (UE), transmission of at least one positioning reference signal (PRS) to a second UE via a sidelink (SL) communication based on first positioning assistance data. The transmission enables the second UE to determine positioning measurements from at least part of the at least one PRS.

Abstract: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a serving cell and a target cell and a processor communicatively coupled to the transceiver. The processor is configured to receive a handover command from the serving cell. The handover command comprises an epoch index and ephemeris information of the target cell. The processor is further configured to determine an epoch time of the target cell based on the epoch index and perform time synchronization with the target cell using the epoch time and the ephemeris information.

Abstract: Disclosed are techniques for differentiating between licensed and unlicensed bands in a common portion of frequency spectrum to facilitate initial access in a fifth generation (5G) new radio (NR) wireless communication system having an NR node. The techniques include an NR generating and UE processing frequency configuration information indicating whether the common portion of frequency spectrum is allocated as a licensed band or an unlicensed band to enable a determination that the frequency spectrum is configured as the licensed band or unlicensed band and thereby facilitate initial access.

Abstract: To support layer 1 (L1) and layer 2 (L2) centric inter-cell mobility and inter-cell multi-TRP operation, a user equipment (UE) may need to measurement the downlink reference signals from neighbor cells. To obtain these measurements, a UE may perform layer 3 (L3) measurements for one or more neighboring cells, and provide an L3 measurement report to a network node. Candidate measurement neighboring cells for L1 measurements may be identified based on the L3 measurements.

Abstract: Provided is a method for a user equipment (UE). The UE obtains, from a network device, a first configuration information. The first configuration information indicates a first resource set for an aperiodic Sounding Reference Signal (AP-SRS). The first resource set for the AP-SRS includes a first list of slot offsets. The UE decodes a second configuration information from the network device. The second configuration information indicates a reference slot and a first slot offset of the first list of slot offsets. The UE generates the AP-SRS for transmission to the network device based on the reference slot and the first slot offset.

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: The exemplary embodiments relate to a user equipment (UE) performing radio link monitoring of a sidelink. The UE may transmit a signal over the sidelink and receive an indication of a type of hybrid automatic repeating request (HARQ) feedback in response to the signal. The UE may then generate a radio link metric associated with the sidelink based on the type of HARQ feedback. The UE may determine that the radio link metric satisfies a predetermined threshold and initiate a keep alive procedure for the sidelink based on the radio link metric satisfying the predetermined threshold.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to provide SCell activation. In one example, a UE may support carrier aggregation in a high speed mode, such FR1 CA in HST. Serving cells can be particularly configured for the carrier aggregation based on the UE's capability to support carrier aggregation in the high speed mode. Additionally or alternatively, an SCell activation procedure can be performed based on this capability.
