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 physical channel may each be reduced by Fourier transform (FFT) size for the V2V the same factor. Doing so may enable the V2V physical channel to be implemented without significant modifications to other aspects of the LTE standard.

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: Embodiments of a User Equipment (UE) and methods for communication are generally described herein. The UE may be configured for carrier aggregation using a primary component carrier (CC) and a secondary CC. The UE may attempt to detect a sidelink synchronization signal (SLSS) from another UE on the primary CC. The UE may, if the SLSS from the other UE is detected: determine, based on the detected SLSS, a common time synchronization for the primary CC and the secondary CC for vehicle-to-vehicle (V2V) sidelink transmissions in accordance with the carrier aggregation. The UE may, if the SLSS from the other UE is not detected: transmit an SLSS to enable determination of the common time synchronization for the primary CC and the secondary CC by the other UE. The SLSS may be transmitted on the primary CC.

Abstract: Methods, systems, and storage media for reporting geo-information in wireless communications networks are described. In embodiments, a roadside unit (RSU) may instruct or configure a user equipment (UE) to report its geo-information to other UEs and/or receive other geo-information from the other UEs over vehicle-to-vehicle (V2V) sidelinks. In embodiments, the RSU or a core network element may allocate radio resources for V2V communications to geographic areas and/or based on reported geo-information. In embodiments, the UE may use its geo-information and/or the obtained geo-information to select resources from the allocation for transmission or receipt of V2V messages. Other embodiments may be described and/or claimed.

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: An approach is described to for new radio (NR) antenna test function (ATF) measurements by a user equipment (UE). The approach includes measuring a first average phase of receive signals on resource elements that carry secondary synchronization signals (SS) received by a reference individual receiver branch. The approach also includes measuring a second average phase of the receive signals on the resource elements that carry secondary synchronization signals received by one other individual receiver branch different from the reference individual receiver branch. The approach further includes determining a difference between the first average phase and the second average phase. An indication of the difference is reported to test equipment.

Abstract: Cellular (e.g., LTE or UMTS) and global navigation satellite system (GNSS) based technologies can provide ubiquitous and seamless synchronization solution for LTE-based vehicle to everything (V2X) or Proximity Services synchronization (ProSe) services. For example, by using joint GNSS timing references and LTE cellular network timing references for V2X or ProSe system synchronization benefits of using GNSS technologies to improve synchronization procedure for LTE based V2X or ProSe services can be enabled, including: (1) accurate and stable timing, (2) availability of a global and stable timing reference and (3) ability to propagate GNSS timing by user equipment having sufficient GNSS signal quality.
