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: 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: A user equipment (UE) can include processing circuitry coupled to memory. To configure the UE for New Radio (NR) communications above a 52.6 GHz carrier frequency, the processing circuitry is to decode radio resource control (RRC) signaling to obtain a cyclic shift value in time domain. The cyclic shift value is associated with a demodulation reference signal (DM-RS) antenna port (AP) of a plurality of available DM-RS APs. A single carrier based waveform DM-RS sequence corresponding to the DM-RS AP is generated using a base sequence and the cyclic shift value. The single carrier based waveform DM-RS sequence is encoded with uplink data for transmission to a base station using a physical uplink shared channel (PUSCH) using a carrier above the 52.6 GHz carrier frequency.

Abstract: A wireless communication device is configured to perform demodulation of device-to-device (D2D) communication signals or LTE uplink signals in a User Equipment. In a transmitter, demodulation reference signal (DMRS) generation circuitry is provided for selective insertion of DMRS signals in resource elements of resource blocks of the signal for transmission using a pattern of resource elements spanning at least one of the resource blocks such that a minimum temporal spacing between consecutive symbols of the demodulation reference signal pattern is less than one slot. In a receiver the DMRS signals are used to perform channel estimation. A user equipment having the DMRS generation circuitry is provided. A computer program product is also provided. Other embodiments may be described and claimed.

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.
