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: This disclosure relates to techniques for determining a quasi-co-located assumption for aperiodic channel state information reference signals for multi-transmission-reception-point operation in a wireless communication system. A wireless device may establish wireless links with multiple transmission-reception-points of a cellular network. The wireless device may receive downlink control information. The wireless device may determine a quasi-co-located assumption for aperiodic channel state information reference signals for the downlink control information. Signals received according to the quasi-co-located assumption for aperiodic channel state information reference signals may be buffered by the wireless device if a scheduling offset for the downlink control information is below a scheduling offset threshold.

Abstract: Sidelink positioning for wireless communications may be achieved by extending the current LCS (LoCation Services) architecture, ProSe (PROximity based SErvices) architecture, and V2X (Vehicle-to-Everything) architecture to include sidelink positioning, e.g., during New Radio (NR) wireless communications. The existing architecture infrastructures of LCS, ProSe and V2X may be expanded to include additional signaling and/or they may be modified to incorporate communication of sidelink positioning information into existing signaling, and/or modify existing signaling to carry instructions between user equipment devices (UEs) as well as between UEs and relevant network functions either directly or via base stations when applicable.

Abstract: Methods, systems, and apparatuses for synchronizing data transmission activity by user equipment (UE). In one aspect, the method comprises determining, by the UE and based on current usage of resources, that alignment of subsequent usage of resources is to be adjusted, generating, by the UE, data that indicates a plurality of activity alignment parameters that are to be adjusted in order to cause the adjusted alignment of subsequent usage of resources, encoding, by the UE, the generated data for transmission to a base station, and transmitting, by the UE, the encoded data to the base station.

Abstract: A wireless network may include a base station and user equipment (UE). The UE may transmit uplink (UL) signals to the base station using a dynamically adjustable maximum UL duty cycle. When the UE identifies that a user is in proximity to the UE, the UE may transmit an indicator to the base station. The indicator may identify that a radio-frequency exposure (RFE) event has occurred and/or a suggested maximum UL duty cycle that would allow the UE to satisfy limits on RFE. The base station may limit a UL grant to the UE so that the UE performs subsequent communications using the suggested maximum UL duty cycle or a different maximum UL duty cycle. Coordinating adjustment of UL duty cycle in this way may allow the UE to meet limits on RFE without requiring the UE to perform maximum transmit power level reductions.

Abstract: Reporting UL Tx DC sub-carrier location information may include decoding a radio resource control (RRC) message received from a base station. The RRC message may comprise a configuration for dynamically reporting uplink (UL) transmit (Tx) direct current (DC) sub-carrier location information. A change associated with at boast one previous UL Tx DC sub-carrier location may be determined to have occurred, thereby creating at least one new UL Tx DC sub-carrier location. In response to determining the change, a medium access control (MAC) control element (MAC CE) may be encoded for transmission to the base station. The MAC CE may include information corresponding to the at least one new UL Tx DC sub-carrier location.

Abstract: Techniques for physical uplink control channel (PUCCH) operation with multiple transmission and reception point (multi-TRP) are disclosed. In some embodiments, determining PUCCH transmission repetition may include determining that an original PUCCH transmission overlaps a slot boundary between a first slot for PUCCH transmission and a second slot for PUCCH transmission, and configuring a PUCCH repetition of the original PUCCH transmission. The PUCCH repetition may include one or more symbols of the original PUCCH transmission and may be located in one or more slots other than the first slot and the second slot. The PUCCH repetition may be configured by a downlink control information (DCI) configuration that includes a physical downlink shared channel to hybrid automatic repeat request acknowledgement feedback (PDSCH-to-HARQ_feedback) timing indicator, a PUCCH repetition number field that configures a number of transmissions of the PUCCH repetition, or a PUCCH resource indicator field that configures a number of transmissions of the PUCCH repetition.
