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 SyncRef UE, 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: 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: 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: 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: 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: 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.
