Abstract: Methods, systems, and devices are described for wireless communication at a UE. In accordance with the present disclosure, a number of user devices in a network may be divided into a plurality of service groups based in part on priority levels associated with each group. In some examples, a network may distribute a plurality of resource pools to each of the above-assigned groups. Thus, for proximity based service (ProSe) communication, user devices within each group may select resource pools corresponding to the priority levels of the groups associated with the user device. Thus, in accordance with the present disclosure, division of resources based on priority levels of groups and UEs may ensure greater reliability of access to resources for high priority communication.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a wireless communication user equipment (UE). The apparatus transmits information in a device-to-device (D2D) communication to a second UE, the information indicating whether the second UE should use a direct feedback path to the UE or an indirect feedback path to the UE. The apparatus receives feedback through one of the direct feedback path or the indirect feedback path based on the information indicated in the D2D communication. The apparatus receives a D2D communication from a second UE. The apparatus determines whether to transmit feedback in response to the D2D communication via a direct feedback path to the second UE or via an indirect feedback path to the second UE. The apparatus transmits the feedback in response to the D2D communication in the determined feedback path.

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.

Abstract: A user equipment (UE) may communicate with one or more other UEs using multiple transmissions in a device-to-device (D2D) communications deployment. A number of UEs may be configured with D2D resources, and a transmitting UE may identify available D2D resources from the configured resources. The transmitting UE may identify a resource for a first transmission of a D2D transmission from the available D2D resources, and may identify a second resource for a second transmission of the D2D transmission. The second transmission may be a blind HARQ transmission that may be transmitted to enhance the likelihood that one or more receiving UEs successfully receive the transmission. In some examples, the second resource may be identified based on other available resources within an predetermined time window around the first transmission.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The apparatus receives a D2D resource message based on a change in an uplink-downlink subframe configuration of at least one frame. The D2D resource message enables the apparatus to determine D2D resources allocated for D2D transmissions after the change in the uplink-downlink subframe configuration. The apparatus determines a subset of the D2D resources to be used for performing D2D transmissions based on the received D2D resource message.

Abstract: A user device may receive one or more parameters from a base station to facilitate device-to-device (D2D) discovery. One of the received parameters is a discovery period parameter, which identifies a discovery period in which discovery resources are available for D2D discovery. Once the user device has received the parameters, the user device may use the parameters to participate in D2D discovery.

Abstract: Methods, systems, and devices are describe for signaling protocols for proximity service functions in a wireless communication system. A first wireless device may identify a wireless relay requirement associated with the first wireless device. A proximity service protocol may be initiated between the first wireless device and a second wireless device based at least in part on the identified wireless relay requirement. The proximity service protocol may be initiated prior to an initiation of a communication data exchange between the first wireless device and the second wireless device. A relay link may be established, via the ProSe protocol, between the first wireless device and the second wireless device based at least in part on the identified wireless relay requirement.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be an eNB. The apparatus may be configured to receive a first message from a UE. The first message may include at least one of a first request to participate in D2D positioning or a second request to participate in D2D ranging.

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).
