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: A user equipment (UE) or network device such as a Vehicle-to-Everything (V2X) node, or V2X device operates to configure sidelink signals with another vehicle or node with resources that can be used for ranging and sidelink communications within a Long Term Evolution (LTE) network or a New Radio (NR) network. The UE/device generate or process a broadcast communication of the sidelink signal via an adaptive antenna array or a directional antenna array and forming a directional radiation pattern from a beam sweeping operation based on geo-location information determined based on a sidelink signal. Depending on the geo-location information coordinates or the position of other vehicles or nodes can be derived to select or configure resources for a sidelink communication, including a Sidelink Ranging Reference Signal (SR-RS) and associated sidelink communication data.

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: 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: 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.

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.
