Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB), Evolved Node-B (eNB) and methods of communication are generally described herein. The UE may determine, based on one or more detected synchronization signals, a reference timing to be used for a common synchronization of Long Term Evolution (LTE) sidelink communication on an LTE PC5 interface and New Radio (NR) sidelink communication on an NR PC5 interface in accordance with time division multiplexing (TDM) operation, wherein subframe boundaries of the LTE PC5 interface and the NR PC5 interface are aligned in time. If the UE detects, during a time period, an in-device conflict between a service configured for the LTE PC5 interface and a service configured for the NR PC5 interface, the UE may determine which of the services to support during the time period based on corresponding priorities.

Abstract: A user equipment (UE) configured for multi-antenna communication estimates at least one of a rank indicator and a channel quality indicator for device to device (D2D) based on communication data associated with a plurality of packets communicated using D2D communication and without using a dedicated reference signal for D2D communication. The UE may be configured as at least one of a transmitter (Tx) and a receiver (Rx) for vehicle-to-everything (V2X) communication through a sidelink channel.

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: 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: 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: 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.
