Abstract: Systems, methods and circuitries are provided for performing UE autonomous selection in a vehicle-to-anything (V2X) communication environment, that includes one or more processors configured to schedule resources for discontinuous periodic transmission having a scheduled discontinuous time period in which scheduled resources are not transmitted. The one or more processors are further configured to perform a monitoring operation at the scheduled discontinuous time period, the monitoring operation comprising a monitoring for a collision of scheduled resources of the evaluating UE with scheduled resources of a competing UE, and selectively perform a corrective action when a collision of scheduled resources of the evaluating UE with scheduled resources of the competing UE is detected during the monitoring operation.

Abstract: An evaluating user equipment (UE) includes memory and one or more processors communicatively coupled to the memory. The one or more processor are configured to schedule periodic resources with one or more configured feedback-based collision detection parameters, and perform a periodic transmission to one or more receiving UEs. The one or more processors are also configured to collect negative acknowledgement (NACK) statistics for the periodic transmission according to the configured feedback-based collision detection parameters, and selectively perform corrective action based on the collected NACK statistics and at least one of the configured feedback-based collision detection parameters.

Abstract: Techniques for physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH) processing for multiple transmission and reception point (multi-TRP) are disclosed. In some embodiments, determining PDSCH hybrid automatic repeat request-acknowledgement (HARQ-ACK) processing timing may include determining that a user equipment (UE) is configured for single downlink control information (single-DCI) multi-TRP PDSCH operation, determining a first PDSCH and a second PDSCH within a slot, wherein the first PDSCH and the second PDSCH are used in the single-DCI multi-TRP PDSCH operation, and determining a minimum HARQ-ACK processing timing for the first PDSCH and the second PDSCH using one or more symbols of the first PDSCH or one or more symbols of both the first PDSCH and the second PDSCH.

Abstract: Supporting transmission of multiple hybrid automatic repeat request acknowledgments (HARQ-ACKS) within a single slot may include encoding a first HARQ-ACK and a second HARQ-ACK within the single slot for transmission to a base station. The first HARQ-ACK may be transmitted via a first physical uplink control channel (PUCCH) and the second HARQ-ACK may be transmitted via a second PUCCH. Based on encoding the first HARQ-ACK and the second HARQ-ACK within the single slot, one or more additional uplink (UL) signals colliding with at least one of the first HARQ-ACK and the second HARQ-ACK within the single slot may be responded to based on a configuration of the UE.

IPC: H04W72/04
Abstract: A method determines a number of physical sidelink shared channel (PSSCH) symbols and a number of PSSCH demodulation reference signal (DMRS) symbols that will occur in a timeslot that is used for scheduling. PSSCH DMRS locations in the timeslot are derived based on applying the PSSCH DMRS symbols and the PSSCH DMRS symbols to a look-up table. A number of PSSCH DMRS resource elements (REs) is calculated based on the PSSCH DMRS locations and a scheduled number of PSSCH sub-channels. This number of PSSCH DMRS REs is used to determine a transport block size (TBS) included in transmissions over a sidelink channel.

Abstract: Some embodiments include an apparatus, method, and computer program product for using group based reporting for beam management in a 5G wireless communications system. A user equipment (UE) can determine based on a signal-to-interference-plus noise ratio (SINR) or reference signal received power (RSRP) measurement, a ranking of two or more beam combinations, and transmit the ranking to a 5G node B (gNB). The UE can receive from the gNB, a transmission configuration indicator (TCI) codepoint that identifies a combination of two or more beams, where the TCI codepoint is based at least on the ranking. The UE can receive simultaneous transmissions via the combination, and transmit a report to the gNB that identifies by the TCI codepoint, SINRs that corresponds to the combination. In some embodiments the UE can simultaneously transmit on a second combination identified by a sounding reference signal (SRS) resource indicator (SRI) codepoint.

Abstract: Apparatuses, systems, and methods for performing timing synchronization between a base station and a user equipment device within an unlicensed spectrum band. In some scenarios, beamforming tracking may also be performed. Upon determining that a transmission medium within the unlicensed spectrum band is available for transmission, a base station may transmit a plurality of synchronization signal blocks (SSBs), or a plurality of copies of one SSB, with associated remaining minimum system information (RMSI) blocks, within a single time instance within a SSB burst window. The SSBs may be transmitted at different frequency positions and according to distinct beamforming configurations. The SSBs and RMSI blocks may be configured such that a receiving user equipment device may determine the time-domain, and optionally the frequency-domain, position of the SSB and RMSI within the SSB burst window, to allow timing synchronization and optionally beamforming tracking.
