Abstract: Aspects of the disclosure relate to beamforming from a vehicle user equipment (UE). In a first aspect, a beamform vector is selected based on beamform data received from a scheduling entity. Here, the beamform data corresponds to a path between a vehicle UE and a base station or another vehicle, and the beamform vector includes respective phases and amplitudes corresponding to each of a plurality of antennas of the vehicle UE. A beam is then generated in accordance with the beamform vector. In another aspect, a database of beamform data is maintained, and beamform data from the database is retrieved. Here, the retrieved beamform data corresponds to a particular location pair that includes a first location associated with a location of a vehicle UE, and a second location associated with a location of a base station or another vehicle. The beamform data is then transmitted to the vehicle UE.

Abstract: A cross-carrier scheduling scheme is provided. The cross-carrier scheduling scheme may improve the resource scheduling, for example, in V2X communication. The apparatus (e.g., a UE) receives a resource grant on a first carrier for a second carrier, the resource grant assigning resources for the second carrier. The apparatus communicates with a second UE via the second carrier using the granted resources. The apparatus may apply the resource grant based on at least one offset, such as an offset between the timing of the first carrier and timing of the second carrier.

Abstract: Low latency enhancements for communication systems, including autonomous driving and/or selection scenarios, are provided. A method for communication includes monitoring communication resources in a communication system, determining a set of candidate resources to use for subsequent transmission of information within a time window such that the time window is minimized based on a desired communication latency parameter that considers at least one or more of communication channel congestion and a priority of transmission, determining a set of lowest energy resources from the set of candidate resources, selecting a low energy resource from the set of lowest energy resources, and transmitting data on the selected low energy resource. Other aspects, embodiments, and features are also claimed and described.

The sensor data collected from each vehicle may be divided into common information and detailed information. The common information is broadcasted to every other nearby vehicle. Based on the received common information other vehicles may express interest in some particular detailed information. Unicast and/or multicast sessions may be set up to share the detailed information with the interested vehicles.

Abstract: Methods, systems, and devices are described for vehicle-to-everything (V2X) communication over one or more determined transmission time intervals (TTIs) in an unlicensed (shared) radio frequency spectrum band. A user equipment (UE) such as a vehicle may perform one or more listen-before-talk (LBT) mechanisms on the shared radio frequency spectrum and contend for access to available system resources. Upon gaining access, the UE may determine a data payload for transmission. The data type or payload may exceed a threshold and as a result, the UE may bundle a multiple TTIs for continuous data transmission. The UE may send control information, indicating a TTI bundling implementation as well as modification to the control or LBT symbols of subsequent TTIs of the data transmission, and subsequently perform data transmission over a plurality of TTIs.

Abstract: Methods, systems, and devices for wireless communication are described. A transmitting device may select an orthogonal metric based at least in part on at least one of each direction of a plurality of directions to transmit millimeter wave discovery signals or a location parameter associated with the transmitting device. The transmitting device may transmit, in the each direction of the plurality of directions, the millimeter wave discovery signals, where the each transmitted millimeter wave discovery signal has a different orthogonal metric applied that was selected based at least in part on the at least one of the each direction or the location parameter.

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: A method, computer-readable medium, and apparatus operate to reduce or eliminate interference with one or more other communication systems having specific transmission requirements within a specific geographic area. For example, aspects operate by determining that a user equipment (UE) is in a protection zone where additional transmission requirements apply. The additional transmission requirements enable coexistence with one or more other communication systems in the protection zone. The UE may identify, based on being in the protection zone and a coexistence mode, one or more transmit emission limit requirements to be met. The UE may identify, based on being in the protection zone and the coexistence mode, one or more maximum transmit power requirements to be met. The UE may configure a transmit output power, at which the UE can meet the one or more transmit emission limit requirements and the one or more maximum transmit power requirements.

Abstract: Wireless communications systems and methods related to transmission of platoon information. A first vehicle in a vehicle platoon obtains a first radio resource spanning a frequency channel and a time period for synchronous transmission with at least a second vehicle in the vehicle platoon. The first vehicle transmits, synchronously with at least the second vehicle, information associated with the vehicle platoon in the frequency channel and the time period of the first radio resource. The first vehicle may obtain the first radio resource by requesting a transmission request from a wireless communication device and receiving a transmission grant indicating the first radio resource. Alternatively, the first vehicle may obtain the first radio resource by selecting the first radio resource based on at least one of a sensing report or a resource reservation received from the second vehicle.
