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: Techniques for scheduling assignment (SA) transmissions in device-to-device (D2D) communications are described. A D2D user equipment (UE) may use a block of time resources for SA transmissions. A D2D UE may transmit an SA transmission relatively quickly after determining that D2D data is to be transmitted to another D2D UE, relative to having to wait for specified time resources to send an SA transmission. The D2D data may then be transmitted following the SA transmission, reducing latency for transmission of the D2D data. It may be desirable for vehicle-to-vehicle (V2V) transmissions to have a relatively low latency to provide data from one vehicle to another with sufficient time for a vehicle to take action while moving at relatively high rates of speed.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE), e.g., a lead platooning vehicle configured for wireless communications, may determine a communication resource requirement for a group of platooning vehicles. The communication resource requirement may be based at least in part on a number of vehicles forming the group of platooning vehicles and a communication range of at least a portion of the vehicles. The UE may identify, based at least in part on the identified communication resource requirement, an assignment of time-frequency radio resources to use for inter-vehicle communications in the group of platooning vehicles. The UE may transmit an indication of the assignment of time-frequency radio resources to the group of platooning vehicles.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine to use multi-cluster communications in a vehicle based communication network. The UE may identify a configuration parameter associated with the multi-cluster communications. The UE may select a cluster resource from a set of available cluster resources based on the configuration parameter. The cluster resource may include one or more clusters used for multi-cluster transmissions in the vehicle based communication network. The UE may transmit an indication of the selected cluster resource to a wireless node of the vehicle based communication network, for example, to another UE. The UE may transmit the multi-cluster transmission on the selected cluster resource.

Abstract translation: 描述了在设备到设备（D2D）通信中调度分配（SA）传输的技术。 D2D用户设备（UE）可以使用一组用于SA传输的时间资源。 相对于必须等待指定的时间资源来发送SA传输，D2D UE可以在确定将D2D数据发送到另一个D2D UE之后相对快速地发送SA传输。 然后可以在SA传输之后发送D2D数据，从而减少D2D数据传输的延迟。 车辆到车辆（V2V）传输可能具有相对低的延迟以将数据从一个车辆提供给另一个车辆可能需要足够的时间来使车辆在以相对高的速度移动的同时采取行动。

Abstract: Methods and devices are described for forwarding, managing, and/or detecting timing information for device-to-device discovery. Timing information may be received from a base station. A timing signal including the timing information may be transmitted. The timing signal may be transmitted during a sub-frame reserved for device-to-device discovery. Timing information for a base station may be transmitted to a user equipment (UE). Instructions to transmit a timing signal including the timing information during a sub-frame reserved for device-to-device discovery are also transmitted to the UE. Information indicating a timing of sub-frames reserved for device-to-device discovery by a neighboring base station may be received from a serving base station. A timing signal may be detected during at least one of the sub-frames reserved for device-to-device discovery. The timing signal may include timing information for the neighboring base station.
