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: This disclosure relates to techniques for scheduling multiple downlink transmissions using a single downlink control transmission in a wireless communication system. A wireless device may determine a beam configuration for use for receiving multiple downlink transport blocks scheduled by a single downlink control transmission. In some instances, the wireless device may be configured to skip one or more control channel monitoring occasions that overlap with the downlink transport blocks. The wireless device may provide hybrid automatic repeat request feedback for the downlink transport blocks.

Abstract: This disclosure relates to techniques for performing wireless communications including schedules for multiple communications between a user equipment device (UE) and a base station. Techniques for updating such schedules are disclosed. The update may be explicitly signaled or may be determined implicitly. The UE and the base station may perform communications according to the updated schedule.

Abstract: A base station (BS) may receive a plurality of repetitions of a Physical Uplink Control Channel (PUCCH) from a user equipment (UE), and accumulate the received repetitions to obtain a resultant signal. The ability to accumulate repetitions enables the base station to experience a higher probability of successful recovery of the PUCCH payload bits than if decoding were based on the reception of a non-repeated transmission of the PUCCH. The base station may configure the number of repetitions, the temporal gap between the repetitions, and mode of repetition of the PUCCH. In an intra-slot mode, more than one copy may be received from each configured slot, with or without frequency hopping. In an inter-slot mode, one copy is received per configured slot. Different repetitions may be transmitted by the UE in different directions, according to a spatial consistency pattern.

Abstract: A user equipment (UE) configured to transmit a scheduling request (SR) to a second UE which causes the second UE to determine a set of sidelink transmission resources for use by the UE. The UE may then receive information regarding a determined set of sidelink transmission resources from the second UE and then transmit sidelink communications using at least a subset of the determined set of sidelink transmission resources. The determined set of sidelink transmission resources may be recommended and reserved or non-reserved resources. The UE may transmit configuration information concerning transmission resources to the second UE to be used in transmitting, the SR. The second UE may monitor the channel for arrival of the resources. The SR may be encoded as a cyclic shift of the SR corresponding to an ACK-only sequence, an ACK/NACK sequence, or a certain sequence of the SR based on a configuration index.

Abstract: Embodiments are presented herein of apparatuses, systems, baseband processors, and methods for performing vehicle-to-everything sidelink communication. A wireless device receives first control information through a sidelink control channel specifying one or more first time slots for the wireless device to transmit a first acknowledgment message over a sidelink feedback channel. The wireless device transmits second control information through the sidelink control channel specifying one or more second time slots for the wireless device to receive a second acknowledgment message over the sidelink feedback channel. The first and second time slots at least partially overlap, and it is determined whether the first data packet or the second data packet has a higher priority. The acknowledgment message associated with the higher priority data packet is transmitted or received during at least a subset of the overlapping time slots.

Abstract: Improved solutions for reliable physical channel, e.g. Physical Downlink Shared Channel (PDSCH) reception during wireless communications, for example during 3GPP New Radio (NR) communications include continuous channel repetitions that cross slot boundaries, channel repetitions with multiple frequency hops, and joint-repetition channel estimation that uses demodulation reference signals from at least two channel repetitions for the channel estimation. In one aspect, reliable PDSCH reception may have the benefit of aiding target UEs and serving base stations in implementing reliable Multicast and Broadcast Services (MBS).

Abstract: A wireless communication system may adapt physical downlink control channel (PDCCH) monitoring behaviors using downlink control information (DCI). The change in monitoring behavior may be skipping or switching. The timeline for applying switching or skipping may be applied after a reference point and a processing time. In some embodiments, the processing time may be either based on UE processing, network processing, or a combination.
