Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE determines a second set of resource block pairs on which to transmit a peer discovery message in a second time cycle based on a mapping of a first set of resource block pairs in a first time cycle to the second set of resource block pairs in the second time cycle. The mapping is a one-to-one mapping between each resource block pair in the first set of resource block pairs to a corresponding resource block pair in the second set of resource block pairs. Resource block pairs in the first set of resource block pairs may be in adjacent allocated resources. The UE transmits the peer discovery message in the determined second set of resource block pairs.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines a first link quality. The first link quality indicates a link quality of a first link between a first potential relay UE and the remote UE. The apparatus determines a second link quality. The second link quality indicates a link quality of a second link between the first potential relay UE and a first base station. The apparatus ranks the first potential relay UE relative to a second potential relay UE. The ranking of the first potential relay UE is based on a combination of the first link quality and the second link quality. The apparatus selects one of the first potential relay UE and the second potential relay UE for a relay connection based on the ranking of the first potential relay UE relative to the second potential relay UE.

Abstract: Methods, systems, and devices are described for utilization of an unlicensed radio frequency spectrum band for performing a ranging procedure. Performance of the ranging procedure may be triggered by a signal transmitted in a licensed radio frequency spectrum band. While conventional ranging in Long Term Evolution (LTE) communications, for example, using the licensed radio frequency spectrum band may be limited to a 10 MHz bandwidth, using the unlicensed radio frequency spectrum band for ranging may allow use of a wider bandwidth, such as 100 MHz or greater. Use of the wider bandwidth may result in more accurate ranging measurements (e.g., time-of-arrival estimation).

Abstract: A user device may transmit a request to a base station for an allocation of device-to-device (D2D) discovery resources. In response to the request, the user device may receive from the base station a response that indicates whether the D2D discovery resources allocated to the user device are common or dedicated.

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 are described for transmitting or receiving at least one grant to a device. The at least one grant may identify one or more scheduling assignment (SA) resources on which an SA is to be transmitted by the device for device-to-device (D2D) communications. The at least one grant may also identify one or more data resources on which data is to be transmitted by the device for D2D communications.

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: Methods, systems, and devices are described for switching a mode of operations in device to device (D2D) communications. A UE within the coverage area of a base station may communicate directly with other UEs using a centralized transmission resource schedule. Prior to experiencing radio link failure (RLF), the UE may determine that switching parameters have been met and transition to an intermediate mode based on a distributed transmission schedule using a pool of resources established by the base station. In one example, the switching parameters may be received from the base station in a connection response message. In another example, the UE may send a switching request to the base station prior to initiating the transition to the intermediate mode. In some cases, after the transition to the intermediate mode, the UE may experience a radio link failure and transition to a distributed mode using a predetermined pool of resources.
