Abstract: PUCCH carrier switching at a UE may include decoding an RRC configuration including a time-domain pattern indicating a reference cell and a target PUCCH cell for one or more PUCCH transmissions at a given point in time. The reference cell may include a reference cell slot numerology and the target PUCCH cell may include a target PUCCH cell slot numerology. A slot for PUCCH transmissions may be determined based on the reference cell slot numerology. The determined slot may be used for transmission of at least one of an SR, a CSI, and a HARQ-ACK. The determined slot of the reference cell may be mapped to a corresponding slot of the target PUCCH cell. A PUCCH resource may be determined for performing a PUCCH transmission using the corresponding slot of the target PUCCH cell. The PUCCH resource determination may be based on a PUCCH configuration of the target PUCCH cell.

Abstract: A user equipment (UE) is configured to provide a power headroom report (PHR) to a network. The UE receives a physical uplink shared channel (PUSCH) configuration from a base station of the wireless network, wherein the PUSCH configuration includes a plurality of beams over which PUSCH repetitions should be transmitted, determines at least one power headroom report (PHR) based on a power control parameter set corresponding to at least one of the plurality of beams or PUSCH repetitions and transmits the at least one PHR to the base station.

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: A cell transmits synchronization signal blocks (SSB) to a user equipment (UE) for the UE to synchronize with the cell. The cell configures a discovery reference signal (DRS) window for synchronization signal block (SSB) transmission to a user equipment (UE), determines that a channel in an unlicensed spectrum is not occupied and transmits multiple SSBs to the UE in response to determining that the channel in the unlicensed spectrum is not occupied.

CPC classification number: H04W52/0212 , H04L5/0048
Abstract: A user equipment (UE) may perform sounding reference signal (SRS) switching by transmitting one or more SRS using a plurality of SRS resources of an SRS resource set configured for SRS switching according to a first combination of downlink (DL) and uplink (UL) antenna ports. For UE power saving, the UE may turn off one or more of the DL and UL antenna ports. The UE may then reconfigure the plurality of SRS resources of the SRS resource set for SRS switching according to a second combination of the DL and UL antenna ports. In response to a power saving message from a UE, a base station may generate SRS configuration information to configure an SRS resource set for SRS antenna switching based on a combination of active DL and UL antenna ports at the UE, and send the SRS configuration information to the UE.

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.
