    Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB), Evolved Node-B (eNB) and methods of communication are generally described herein. The UE may detect one or more LTE synchronization signals from an eNB over an LTE Uu interface between the UE and the eNB. The LTE synchronization signals may be detected in resources allocated for LTE communication. The LTE synchronization signals may be detected in accordance with an LTE protocol. The UE may determine, based on the LTE synchronization signals, a reference timing and a reference frequency for NR vehicle-to-everything (V2X) communication over an NR PC5 interface with another UE.

    Abstract: Systems, methods, and circuitries are disclosed for determining a position of a wireless device. In one example, an apparatus for a first wireless communication device including baseband circuitry having a radio frequency (RF) interface configured to transmit and receive RF signals is provided. The apparatus includes one or more processors configured to process a signal received from a second wireless communication device to identify at least first arrival path and a different arrival path between the first wireless communication device and the second wireless communication device; and determine a location of the second wireless communication device based on the first arrival path and the different arrival path.

    Abstract: A user equipment (UE), gNodeB or network component can be configured to support a data-aided sidelink synchronization. In response to losing a sidelink synchronization reference, sidelink synchronization tracking or performing an initial sidelink synchronization, data-aided sidelink synchronization can be performed by deriving or maintaining a sidelink synchronization from a physical sidelink control channel (PSCCH), or a physical sidelink shared channel (PSSCH) transmission of another network device, UE or vehicle to everything (V2X) based on data of another reference signal that is with the PSCCH or the PSSCH transmission.

    Abstract: An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for New Radio (NR) vehicle-to-everything (V2X) sidelink communication. The processing circuitry is to determine a set of candidate resources of the UE from a sidelink resource pool, the sidelink resource divided into multiple time slots, frequency channels, and frequency sub-channels. Sidelink control information (SCI) is encoded for transmission to a second UE via a physical sidelink control channel (PSCCH). The SCI indicates a plurality of transmission resources of the set of candidate resources. A transport block is mapped across the plurality of transmission resources. A physical sidelink shared channel (PSSCH) is encoded for transmission to the second UE using the plurality of transmission resources, the PSSCH encoded to include the mapped transport block.

    Abstract: Embodiments of a User Equipment (UE) and methods of communication are generally described herein. The UE may select one or more of the component carriers (CCs) of a carrier aggregation, and may transmit a sidelink synchronization signal (SLSS) and a physical sidelink broadcast channel (PSBCH) on the one or more selected CCs. The UE may encode the PSBCH to include a plurality of parameters related to the sidelink operation, wherein the plurality of parameters are to be propagated across all of the CCs of the plurality of CCs for the sidelink operation. The UE may transmit one or more physical sidelink shared channels (PSSCHs) in accordance with the carrier aggregation, and further in accordance with the plurality of parameters propagated across the plurality of CCs.
