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: The present disclosure provides for centralized, scheduler-based handling for UEs which transmit data to and receive data from a maneuver coordinator based on V2X communication. Once a UE is aware of the maneuver coordinator, the UE may send a request to the maneuver coordinator for maneuver operation scheduling. The maneuver coordinator then schedules and coordinates the UE's operation.

Abstract: Techniques for device to device (D2D) wireless communication are provided. In an aspect, a first user equipment (UE) receives device-to-device (D2D) information from a second user equipment (UE). The first UE determines whether the first UE is within a threshold range from the second UE based on the D2D information. Application layer processing is enabled for a message in the D2D information, if the first UE is within the threshold range. The message is blocked from the application layer, if the first UE is not within the threshold range from the second UE.

Abstract: Methods, systems, and devices for wireless communications are described. A human user, such as a pedestrian, cyclist, or driver, may provide a feedback message to a vehicle whose behavior they observe. The feedback message and the recipient may be manually identified by the human user or may be suggested by the system or device. The feedback message may be broadcast and filtered by vehicles within the broadcast radius based on a vehicle identifier. A vehicle that receives the feedback message may discard the feedback message if it applies to another vehicle or may take responsive action if the feedback message applies to the vehicle. For example, the recipient vehicle may display the feedback message, store the feedback message to support related analysis, or relay the feedback message to other vehicles or network devices.

Abstract: A technique is disclosed that changes one or more properties of a user interface at a telecommunications terminal based on an incoming call. When a first caller calls the telephone number of the terminal directly and the terminal answers the call, the terminal presents the direct call to the user through a first user interface. When a second caller calls a telephone number that is associated with a data-processing system and the call is then redirected to the terminal, the terminal presents the redirected call to the user through a second user interface. The telecommunications terminal can be a cell phone that belongs to a user, and the data-processing system can be a private branch exchange that serves an office enterprise network that the user belongs to, wherein the private branch exchange extends the call to the user's cell phone when the user is out of the office.
