Abstract: Described are methods for interference detection and management in a millimeter wave communications system. A V2X communications system may support interference management procedures that comprise scheduling a system wide training interval in a transmission timeslot, suspending traffic transmissions on a link in the communications system during the training interval to perform training on the link, and resuming traffic transmissions on the link if interference is not detected during the training interval. Interference management procedures may also include receiving at a node, unique parameters transmitted from another node in a communication system during a discovery stage, determining whether interference will occur at the node based on the received unique parameters, and suspending transmissions to and from the node if it is determined interference will occur at the node.

Abstract: The present disclosure provides a solution to this problem by enabling the communications network to verify the relationship of the first UE and the second UE based on stored pairing information that is used to verify that the first UE is allowed to make a connection to the communications network. The apparatus transmits a pairing request from a first UE to a second UE. In an aspect, the pairing request is intended for a communication network. Further, the apparatus receives a pairing acknowledgement. In an aspect, the pairing acknowledgement verifies the pairing of the first UE and the second UE. In addition, the apparatus connects to the communication network via the second UE once the first UE pairs with the second UE.

Abstract: Techniques are providing for situationally-dependent service prioritization in a CV2X network. An example method of prioritizing data packets with a mobile device includes determining a range to a waypoint, determining an estimated time of arrival at the waypoint, computing a priority value based at least in part on the estimated time of arrival at the waypoint, and generating a data packet based on the priority value.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) performs a limited beam sweep of one or more transmit beams on a second frequency band in an estimated direction from the first UE to the second UE, wherein the estimated direction is based on one or more parameters received over a previously established signaling radio bearer (SRB) on a first frequency band and/or a device-to-device discovery procedure performed on the first frequency band, receives, over the SRB, a confirmation that a data radio bearer (DRB) has been established on the second frequency band with at least one transmit beam of the one or more transmit beams, and sends, to the second UE, a data flow over the DRB on the second frequency band using the at least one transmit beam.

Abstract: Various aspects of the disclosure relate to limits for modulation and coding scheme (MCS) values. For example, a first set of limits (e.g., minimum and maximum limits) may be used for a first MCS table and a second set of limits may be used for a second MCS table. The disclosure also relates in some aspects to inter-device signaling that indicates which minimum and maximum limits for an MCS table are to be used for communication between the devices.

Abstract: Various aspects of the disclosure relate to the selection and use of modulation and coding scheme (MCS) values. For example, a first MCS table may be used for a first condition and a second MCS table used for a second condition. The disclosure relates in some aspects to inter-device signaling that indicates which MCS table is to be used for communication between the devices.

Abstract: Aspects relate to managing a device-to-device communication link via radio resource control (RRC) layer signaling. In an example operation, a first wireless communication device establishes a unicast link with a second wireless communication device over a device-to-device communication interface and determines that the unicast link is to be reconfigured with at least one updated parameter. The first wireless communication device then sends a link reconfiguration request to the second wireless communication device via a first RRC message over the communication interface. The first RRC message includes the at least one updated parameter. The first wireless communication device receives a link reconfiguration response from the second wireless communication device via a second RRC message over the communication interface based on the link reconfiguration request and determines whether to reconfigure the unicast link using the at least one updated parameter based on the received link reconfiguration response.

Abstract: Certain aspects of the present disclosure provide techniques relating to wireless communications between vehicles. In certain aspects, a method performed by a first vehicle comprises receiving an indication from a second vehicle comprising surrounding information that is indicative of whether a first unknown vehicle is detected by the second vehicle, wherein the first vehicle and the second vehicle are able to communicate wirelessly, and wherein the first unknown vehicle is unable to communicate wirelessly with the first and the second vehicles. The method further comprises controlling movement of the first vehicle based on the indication.

Abstract: Techniques are disclosed for a priori or real-time intersection trajectory determination of a vehicle, and corresponding messaging of the trajectory determination. Trajectory determination may be based on vehicle static characteristics, dynamic characteristics, and/or intersection geometry. Trajectory messages, which can be communicated using CV2X, may not only indicate the trajectory, but may (optionally) indicate which intersection ingress and egress points the vehicle will block over the course of the traversal of the vehicle along the trajectory.
