Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may utilize priority levels associated with packets or transmissions to determine whether to transmit feedback for a received transmission. The UE may compare priority levels between a transmission subject to a feedback condition and a transmission scheduled to be received when the feedback is scheduled to be transmitted to determine whether to send the feedback. The UE may communicate with the transmitting device according to the comparison and the determining. The UE may determine signal conditions causing a NAK and determine to send the NAK based on the signal conditions.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device that uses a first radio access technology (RAT) may identify a transmission timing scheme for a shared radio frequency spectrum band, the transmission timing scheme comprising a first set of time intervals allocated for transmissions using a first RAT and a second set of time intervals allocated for transmissions using a second RAT. The wireless device may transmit, during a time interval of the first set of time intervals, a channel reservation signal indicating an end time of the time interval and indicating that the wireless device uses the first RAT. The wireless device may transmit, based at least in part on the transmitted channel reservation signal, over the shared radio frequency spectrum band during at least a portion of the time interval before the end time of the time interval.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive situational information for a second wireless device over a first communication link between the first wireless device and the second wireless device and situational information for a third wireless device over a second communication link between the first wireless device and the third wireless device. The first wireless device may transmit message with guidance information to the second wireless device on behalf of the third wireless device and based on the second wireless device and the third wireless device having an event likelihood above a threshold. The event likelihood may be based on the situational information for the second wireless device and the situational information for the third wireless device.

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: 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: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a second UE, a first control signal indicating a range value corresponding to a threshold distance for triggering feedback reporting from the first UE for transmissions from the second UE. The first UE may calculate a traversable distance corresponding to a traversable route between the first UE and the second UE, determine, based on the calculated traversable distance and the range value, whether the first UE is within the threshold distance for triggering feedback reporting, and perform, based on whether the first UE is within the threshold distance, a feedback procedure for the feedback reporting. The first UE may receive, from the second UE, a second control signal indicating a type of distance measurement corresponding to the threshold distance for triggering feedback reporting.

Abstract: Certain aspects of the present disclosure are generally directed to techniques for selecting a configuration for communication using vehicle to everything (V2X) type communication protocol. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes determining one or more parameters corresponding to quality of service (QoS) information for communication of data using a V2X communication protocol, reporting the one or more parameters by transmitting a first message, receiving a second message indicating configuration information corresponding to the communication of the data using the V2X communication protocol, and communication the data based on the configuration information.

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.
