Abstract: Uplink transmissions of a mobile device (UE) may be improved in a number of ways. Uplink Transmission Time Interval (TTI) bundling, including both Type-A and Type B PUSCH repetitions, may be implemented with variable TTI bundle sizing. The TTI bundle size may be determined by a base station and communicated to the UE explicitly, or may be determined by the UE implicitly, based on an indicated repetition number and frequency hopping number. The UE may also report frequency hopping (FH) assist information to the base station for use by the base station to more efficiently configure FH for the uplink transmissions. Finally, the UE may use (or maintain) the same transmission power, for each TTI transmit occasion of the same TTI bundle in order to improve (cross-slot) channel estimation accuracy. Power allocation may be prioritized to ensure that at the same time a total power for the uplink transmissions of the UE does not exceed a specified threshold.

Abstract: Systems and methods for using hybrid automatic repeat request acknowledgement (HARQ-ACK) codebooks to as part of acknowledgement/negative acknowledgement (ACK/NACK) signaling regarding multiple physical downlink shared channel (PDSCH) transmissions (also termed “multi-PDSCH”) scheduled by a single downlink control information (DCI) corresponding to multiple candidate PDSCH monitoring occasions are discussed herein. Rate matching indicators for one, multiple, or all of the PDSCHs of a scheduled multi-PDSCH are discussed. Effects of invalid symbol signaling, where one or more resources corresponding to a candidate PDSCH monitoring occasion corresponding to the DCI has been indicated for uplink (UL) use or not for DL use by a base station, are discussed. Effects of a bandwidth part change (in UL or downlink (DL)) occurring near or during the DCI, the multi-PDSCH, and a physical uplink control channel (PUCCH) containing the ACK/NACK signaling (e.g., containing or corresponding to all or part of the HARQ-ACK codebook) are discussed.

Abstract: Techniques described here related to a power headroom power headroom report generation trigger. One aspect of the disclosure includes a user equipment (UE) configured to measure a first path loss change of a first physical uplink shared channel (PUSCH) transmission transmitting from the first antenna panel to a first transmission and reception point (TRP). The UE can further measure a second path loss change of a second PUSCH transmission transmitting from the second antenna panel to a second TRP, the second PUSCH transmission transmitting simultaneously to the first PUSCH transmission. The UE can further determine whether to generate a powerhead report (PHR) based on the measured first path loss change and measured second path loss change. The UE can further generate the PHR based on the determination.

Abstract: Configuring non-zero-power channel state information reference signal (NZP-CSI-RS) may include encoding a channel state information (CSI) configuration communication for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) associated with a serving cell and a second TRP associated with a neighbor cell. The NZP-CSI-RS configuration communication may establish a plurality of parameters for NZP-CSI-RS in the serving cell and the neighbor cell.

Abstract: Disclosed are techniques for reducing likelihood of Random Access Channel (RACH) transmission blockages and thereby facilitate an initial access procedure for new radio (NR) unlicensed spectrum (NR-U) operation in a fifth generation (5G) wireless communication system including an NR node. In some embodiments, a parameter generated by a gNB and received by a UE indicates that, from among a set of consecutive RACH Occasions (ROs), a gap is available for performing a listen-before-talk (LBT) procedure before commencing a RACH transmission.

Abstract: Systems and methods for user equipment (UE) capable of performing sidelink (SL) communications that account for overlapped SL resource pools of multiple radio access technologies (RATs) are disclosed. A UE may select, based on prioritizing non-overlapped resources over overlapped resources, one or more candidate resources and/or one or more transmission resources; may determine a power control configuration without considering SL pathloss corresponding to a first RAT when a second power control configuration determination for a second RAT does not consider SL pathloss; may select physical sidelink feedback channel (PSFCH) locations for PSFCH use from first PSFCH locations of resources of a first SL resource pool on a first RAT that do not overlap with a second SL resource pool on a second RAT according to a bitmap; and/or may select one of a PSFCH transmission and PSFCH reception using a data priority rule and/or a pool sharing rule.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to determine a default beam for a dedicated PUCCH/SRS in a CC. The UE may determine a pathloss RS has been configured in the CC, e.g., responsive to the UE determining that spatial relationship information for a default transmission beam has not been configured and determine the default beam for transmissions based, at least in part, on the (configured) pathloss RS. Additionally, responsive to determining that the pathloss RS has not been configured in the CC, the UE may determine that no CORESETs/TCI states for a PDSCH in the CC have been configured and determine the default beam for transmissions based, at least in part, on a default transmission beam in another CC, a CC index, a PRACH procedure; a PUSCH transmission; an SRS transmission, and/or a PUCCH transmission.
