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.

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: Embodiments of a User Equipment (UE) and methods for communication are generally described herein. The UE may select, from a plurality of short transmission time intervals (TTIs), a short TTI for a vehicle-to-vehicle (V2V) sidelink transmission by the UE. The short TTIs may occur within a legacy TTI. The short TTIs may be allocated for V2V sidelink transmissions by non-legacy UEs. The legacy TTI may be allocated for V2V sidelink transmissions by legacy UEs. The UE may transmit, in accordance with the legacy TTI, a legacy physical sidelink control channel (PSCCH) to indicate, to legacy UEs, the V2V sidelink transmission by the UE. The UE may transmit, in accordance with the selected short TTI, a short PSCCH (sPSCCH) to indicate, to non-legacy UEs, the V2V sidelink transmission by the UE.

Abstract: Methods disclosed herein may include receiving, at a gNB from a UE, a minimum time gap between a reception at the UE of a configuring message that configures a sending of an SL transmission by the UE and the sending of the SL transmission. Alternatively, the minimum time gap may be measured from the reception at the UE of a DCI message that triggers an SL transmission and the sending of the SL transmission. The method may further include determining, at the gNB, timing information (e.g., an offset, or an absolute time) for the UE to use to schedule the SL transmission, the timing information based on the minimum time gap; generating, at the gNB, a message including a field indicating the timing information; and sending, from the gNB, the message to the UE. Analogous methods for UEs are also disclosed herein. Systems implementing these methods are also disclosed.

Abstract: A user equipment (UE), gNodeB or network component can be configured to support a data-aided sidelink synchronization. In response to losing a sidelink synchronization reference, sidelink synchronization tracking or performing an initial sidelink synchronization, data-aided sidelink synchronization can be performed by deriving or maintaining a sidelink synchronization from a physical sidelink control channel (PSCCH), or a physical sidelink shared channel (PSSCH) transmission of another network device, UE or vehicle to everything (V2X) based on data of another reference signal that is with the PSCCH or the PSSCH transmission.

Abstract: Apparatuses, systems and methods associated with asynchronous synchronization reference source selection and reselection for wireless communication devices are disclosed herein. In embodiments, one or more non-transitory, computer-readable media having instructions stored thereon, wherein the instructions, in response to execution by a user equipment (UE), cause the UE to establish a sidelink connection with a first synchronization reference (SyncRef) UE, and monitor for physical sidelink broadcast channel (PSBCH) synchronization signals from a second SyncRefUE, wherein the UE is to drop one or more subframes of data reception of the sidelink connection with the first SyncRef UE when the UE monitors for the PSBCH synchronization signals. Other embodiments may be described and/or claimed.

Abstract: A user equipment (UE) is configured to scan for device-to-device synchronization sources based on scanning configuration information. The UE is configured to report detection of a device-to-device synchronization source to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB) in response to determining that the device-to-device synchronization source meets one or more reporting requirements of the scanning configuration information. The UE is configured to receive a communication from the eNB enabling the UE as a synchronization source and transmit signals to provide a synchronization reference to one or more in-range UEs including the device-to-device synchronization source.

Abstract: Technology for a user equipment (UE) operable to perform adaptive time division duplexing (TDD) hybrid automatic repeat request (HARQ)-ACKnowledgement (ACK) reporting is described. The UE can implement an adaptive uplink-downlink (UL-DL) configuration received from an eNodeB. The UE can decode a downlink (DL) HARQ reference configuration received from the base station for a serving cell, wherein the DL HARQ reference configuration is for the implemented adaptive UL-DL configuration. The UE can decode a reference UL-DL configuration received from the base station via a system information block (SIB). The UE can encode HARQ-ACK feedback for transmission on an uplink channel of the serving cell in accordance with the DL HARQ reference configuration. The UE can perform uplink scheduling and the HARQ-ACK feedback based on the reference UL-DL configuration received from the base station via the SIB.
