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: 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: 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: Systems and methods of providing RAT co-existence and congestion control in V2V communications are generally described. A vUE detects specific non-LTE RAT transmissions in a listening period of a PSCCH or PSSCH, determines whether a metric has been met and reselects to a non-overloaded channel to communicate with other vUEs or the eNB. The manner of reselection is dependent on the RAT specific or V2X service priorities of the channels, as well as whether the channels are V2V service dependent.

Abstract: A wireless communication device is disclosed for setting transmission slot priorities in a broadcast environment. Upon receipt of a broadcast signal from the wireless communication environment, the UE analyzes the received signal to determine time slots in which members of its own group are transmitting. The UE then sets priorities of previously-used time slots to be low for allocation purposes. When the UE needs to transmit a signal, it first performs allocation of time slots within the signal frame. This allocation is performed based on the earlier-set priorities such that time slots identified as being used by other group members will not be used unless necessary.
