Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

Abstract: Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may allocate a resource pool of physical resource blocks (PRBs) and sub-frames for vehicle-to-vehicle (V2V) sidelink transmissions. The gNB may receive, from a UE, an uplink control message that indicates that the UE requests a V2V sidelink transmission of a prioritized message. The gNB may select, for the V2V sidelink transmission of the prioritized message, one or more PRBs and one or more sub-frames. The gNB may transmit, to the UE and to other UEs, a downlink control message that indicates: the selected PRBs, the selected sub-frames, and that the other UEs are to mute sidelink transmissions in the selected PRBs in the selected sub-frames to enable the V2V sidelink transmission of the prioritized message.

Abstract: Implementations of this disclosure generally may relate to the field of wireless communications. More specifically, implementations described in this disclosure relate to different 3GPP LTE and LTE-A system enhancements to address the issue and support reliable V2X operation in the high mobility environments. Several solutions to improve the V2X system performance in the high mobility vehicular channel propagation conditions are described. Some aspects relate to the suggestion of a new DMRS patterns within individual subframes that promote more accurate CFO estimation. Moreover, another aspect provides DMRS mapping or puncturing patterns to transmit individual DMRS in a periodic pattern on respective OFDM/SC-FDMA symbols so that they do not occupy all REs of the OFDM/SC-FDMA symbols, respectively.

Abstract: Devices and methods provide for transmitting downlink (DL) positioning reference signals (PRSs) in a wireless system. A DL PRS resource pool is configured and divided into a plurality of DL PRS resource sets. The DL PRS resource pool includes a periodically repeated amount of resources dedicated for DL PRS transmission by a plurality of gNBs in the wireless communication system. The plurality of DL PRS resource sets correspond to one or more gNB of the plurality of the gNBs. The DL PRSs are encoded for transmission on configured DL PRS resources within the plurality of DL PRS resource sets.

Abstract: A user equipment (UE), gNodeB or network component can be configured to support Quality of Service (QoS) aware sidelink communications for vehicle to everything (V2X) communication operations. The QoS aware sidelink communications can include operating QoS congestion control, QoS control and adaptation, QoS aware resource allocation, QoS aware in-device coexistence operations, as well as sensing and reservation based on sidelink resource allocations. Transmitter constraints can be provided according to a Quality of Service (QoS) aware congestion control that enables a fair usage of spectrum resources with one or more V2X devices, based on QoS attributes. Different V2X packets can be scheduled/filtered based on combinations of the QoS attributes. A priority of one radio access technology (RAT) over another can be made based on the QoS attributes associated with the different V2X packets being delivered in sidelink transmissions for a QoS aware in-device coexistence operation.

Abstract: A method and device are disclosed for performing collision resolution in a two-step random access channel (RACH) process. In such a process, an MsgA PUSCH signal and a grant based PUSCH signal may collide. When such a collision is detected, either the MsgA PUSCH signal or the grant based PUSCh signal are dropped. The other of the two signals is then transmitted. The determination regarding which signal to drop can be based on a set of rules stored in memory.
