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: Systems and methods for sidelink (SL) power control within wireless communication systems are disclosed herein. A user equipment (UE) selects a parameter set to use to calculate a transmit power of one or more channels to be transmitted according to an SL session with a peer UE from a plurality of parameter sets each configured for use according to a distance between the UE and the peer UE. A UE determines whether an SL pathloss based calculation is to be used to calculate a transmit power of a channel according to an SL session with a peer UE, wherein that calculation is configured to be used depending on a distance between the UE and the peer UE. UE selection of a number of physical SL feedback channel (PSFCH) transmissions to match a UE capability and determinations regarding whether to perform PSFCH reception or PSFCH transmission are also discussed.

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.
