Abstract: Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may allocate a resource pool of physical resource blocks (PRBs) and sub-frames for vehicle-to-vehicle (V2V) sidelink transmissions. The gNB may receive, from a UE, an uplink control message that indicates that the UE requests a V2V sidelink transmission of a prioritized message. The gNB may select, for the V2V sidelink transmission of the prioritized message, one or more PRBs and one or more sub-frames. The gNB may transmit, to the UE and to other UEs, a downlink control message that indicates: the selected PRBs, the selected sub-frames, and that the other UEs are to mute sidelink transmissions in the selected PRBs in the selected sub-frames to enable the V2V sidelink transmission of the prioritized message.

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 method for allocating channel resources for transmitting data by user equipment (UE), includes receiving a resource allocation specification for a PSCCH transmission on PSSCH resources. The resource allocation specifies a PSCCH decoding unit of N symbols by M PRBs. The decoding unit is larger than a resource element group (REG) associated with the PSSCH resources. The method includes causing transmission, by a transceiver, of the PSCCH transmission in using the decoding unit specified by the resource allocation specification.

Abstract: Devices and methods provide for transmitting downlink (DL) positioning reference signals (PRSs) in a wireless system. A DL PRS resource pool is configured and divided into a plurality of DL PRS resource sets. The DL PRS resource pool includes a periodically repeated amount of resources dedicated for DL PRS transmission by a plurality of gNBs in the wireless communication system. The plurality of DL PRS resource sets correspond to one or more gNB of the plurality of the gNBs. The DL PRSs are encoded for transmission on configured DL PRS resources within the plurality of DL PRS resource sets.

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: A user equipment (UE), gNodeB or network component can be configured to support Quality of Service (QoS) aware sidelink communications for vehicle to everything (V2X) communication operations. The QoS aware sidelink communications can include operating QoS congestion control, QoS control and adaptation, QoS aware resource allocation, QoS aware in-device coexistence operations, as well as sensing and reservation based on sidelink resource allocations. Transmitter constraints can be provided according to a Quality of Service (QoS) aware congestion control that enables a fair usage of spectrum resources with one or more V2X devices, based on QoS attributes. Different V2X packets can be scheduled/filtered based on combinations of the QoS attributes. A priority of one radio access technology (RAT) over another can be made based on the QoS attributes associated with the different V2X packets being delivered in sidelink transmissions for a QoS aware in-device coexistence operation.

Abstract: A user equipment (UE) or network device such a vehicle UE (V-UE) or pedestrian UE (P-UE) can configure resources independently for communication with other V-UEs/P-UEs to avoid collision and ensure safety. The UEs can operate to independently monitor and configure their own resources via partial sensing window configurations that can dynamically configured to perform resource (re)selection in response to a resource reselection trigger. An exclusion of detected resources that are reduced or occupied by other devices can be performed, and a resource candidate set generated to select resource candidates for long term evolution (LTE) vehicular communications. UE partial sensing mechanisms and congestion control can be enhanced for these communications via efficient power control and signaling reliance for vehicle communication quality, as well as pedestrian safety.
