Abstract: The present disclosure provides techniques for communicating feedback for data transmissions over a sidelink in a wireless communication system. For example, devices and methods are provided for wireless communication by a first wireless device. In one example, the first wireless device determines that only one of either feedback can be transmitted to a second wireless device or a second communication can be communicated, wherein the feedback is indicative of whether a data transmission is successfully decoded, and based on that prioritizes one of the feedback or the second communication. In another example, the first wireless device determines that only one of either feedback can be received from the second wireless device or a second communication can be communicated, wherein the feedback is indicative of whether the data transmission is successfully decoded by the second wireless device, and based on that prioritizes one of the feedback or the second communication.

Abstract: Methods, systems, and devices for wireless communications are described. Examples may include a receiving wireless device located in a first geographic zone receiving multiple signals from one or more transmitting wireless devices. The receiving wireless device may determine based on the received signals that the one or more transmitting devices are located in a second geographic zone. The receiving wireless device may determine configured transmit power information for each of the signals received from the transmitting wireless devices located in the second geographic zone. The receiving wireless device may estimate a path loss of wireless communications between the first geographic zone and the second geographic zone based on the configured transmit powers received in the signals. The receiving wireless device may communicate within the second geographic location based on the estimated path loss between the first geographic region and the second geographic region.

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: 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: Techniques are described that support techniques for directional discovery in a millimeter wave communications system. A vehicle-to-everything (V2X) communications system may support beam discovery procedures that use directional beams to discover other entities, establish directional communication links with other entities, or maintaining directional communication links with other entities. The beam discovery procedure may include a sweep pattern where a transmitting entity may probe with directional beams in a plurality of beam directions. During a beam discovery procedure a transmitting entity may transmit discovery signals in a plurality of different directions and a receiving entity may listen for the discovery signals in a plurality of different directions. The sweep patterns of the transmitting entity and the receiving entity may be coordinated to increase a likelihood that the receiving entity will discover the transmitting entity.

Abstract: An apparatus may comprise a component for communicating using a first RAT and another component for communicating using a second RAT. Overlapping communication using the two RATs may cause problems for proper reception at the apparatus. The apparatus may detect that transmission or reception of a first packet using a first RAT will overlap in time with reception of a second packet using a second RAT. The apparatus prioritizes the first packet or the second packet based at least on a relative priority of the first packet and the second packet.

Abstract: Techniques and apparatus for zone-based soft resource partitioning for high reliability high range communications (HRHRC) are described. A first wireless device determines, based at least in part on a location of the first wireless device and a type of traffic associated with the first wireless device, whether to use a first set of resources or a second set of resources for communications between the first wireless device and a second wireless device. The first wireless device communicates with the second wireless device on the first or second sets of resources, in accordance with the determination. The communications involve the type of traffic.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may establish a unicast connection over a sidelink communications with a second UE. To establish the unicast connection over the sidelink, the first UE may transmit a request message (e.g., a first message) to the second UE, and the second UE may transmit a response message (e.g., a second message) to the first UE accepting the request. The unicast connection over the sidelink may then be established between the first UE and the second UE, and user data may then be transmitted over the sidelink on the established unicast connection. Additionally, the first UE may transmit a connection complete message (e.g., a third message) to the second UE indicating that the unicast connection has been established. The request message, the response message, and the connection complete message may be radio resource control (RRC) messages.
