    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.

    Abstract: Technology for an eNodeB operable to resolve predefined types of concurrent communications at a relay user equipment (UE) is disclosed. The eNodeB can identify the relay UE that is configured to relay proximity services (ProSe) traffic between the eNodeB and a remote UE. The relay UE can be in-coverage of the eNodeB and the remote UE can be in-coverage or out-of-coverage of the eNodeB. The eNodeB can communicate control signaling to at least one of the relay UE and the remote UE to resolve predefined types of communications performed at the relay UE or the remote UE to defined subframes. The control signaling can provide concurrency avoidance at the relay UE for predefined types of concurrent communications between the relay UE and at least one of the eNodeB and the remote UE.

    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: User equipment (UE) positioning within a 5G New Radio (NR) network may be determined by receiving a downlink (DL) position reference signal (PRS) resource set indicating a plurality of DL PRS resources and receiving a DL PRS report configuration that indicates a set of measurements to be performed by a UE for each of the plurality of DL PRS resources within the DL PRS resource set. Position measurements may be performed for each of the plurality of DL PRS resources within the DL PRS resource set, including generating a reference signal time difference (RSTD) measurement by estimating a timing of a first arrival path from at least two of the plurality of DL PRS resources and determining a reference signal received power (RSRP) metric or a signal to noise and interference ratio (SINR) metric associated with the at least two DL PRS resources. The performed position measurements may be reported.

    Abstract: A vehicle may wirelessly communicate with another vehicle via a physical channel (a vehicle-to-vehicle (V2V) channel) that is robust and reliable under high mobility propagation conditions. The physical channel may be created by modifying an existing long-term evolution (LTE) physical channel, such as an LTE sidelink (SL) channel. For instance, the V2V physical channel may be created by increasing, by a particular factor, the subcarrier spacing of legacy LTE channels (e.g., from 15 kilohertz (kHz) to 30 kHz). Additionally, a symbol duration and a fast Fourier transform (FFT) size for the V2V physical channel may each be reduced by the same factor. Doing so may enable the V2V physical channel to be implemented without significant modifications to other aspects of the LTE standard.
