Abstract: Methods, devices, systems, and non-transitory process-readable storage media for a computing device of an autonomous vehicle to generate real-time mappings of nearby vehicles. An embodiment method executed by a computing device may include operations for obtaining origin point coordinates via a first satellite-based navigation functionality, obtaining termination point coordinates via a second satellite-based navigation functionality, calculating a unit vector based on the obtained origin point coordinates and the obtained termination point coordinates, identifying a position, a direction, and an occupancy of the autonomous vehicle based on the obtained origin point coordinates, the calculated unit vector, and stored vehicle dimensions data (e.g., length, width, height), and transmitting a message using DSRC with the origin point coordinates, the stored vehicle dimensions data, and data for identifying the vehicle's direction. The computing device may compare the direction, position, and occupancy to data of nearby vehicles based on incoming messages received via DSRC.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. A multi-radio device controls wireless communications by identifying one or more connection points between radio(s) of the multi-radio device and an operating system executing on a host device, analyzing a policy relating to the multi-radio device, and exposing, to the operating system, a subset of the connection points based on the policy. A modem manages a connection to an applications processor (AP) by virtualizing physical communication interfaces at the modem, providing a single Internet protocol (IP) interface representing the virtualized physical communication interfaces to a high level operating system (HLOS) at the AP, detecting a physical communication interface connected to the modem, and determining whether to expose the detected physical communication interface to the HLOS as a standalone virtualized physical communication interface, or hide the detected physical communication interface as part of an existing virtualized physical communication interface.

Abstract: A user equipment (UE) may mitigate interference on the user equipment with two or more radios. In some instances, the UE may determine when communications of the two or more radios experience interference, in which two radios of the two or more radios operate with the same radio access technology. Further, the UE may alter an operating frequency of a first radio of the two radios to mitigate the interference.

Abstract: In a device with multiple radios, either with multiple internal radios, or with one or more internal radios connected to a peripheral radio, interference between the multiple radios may result in degraded performance by one or more radios. To manage coexistence between the multiple radios in a flexible manner, coexistence messages may be multiplexed with data and sent along a data interface, such as a USB or PCIe interface. In this manner coexistence message may be exchanged without extensive separate coexistence logic.

Abstract: Single-counter, multi-trigger systems and methods in communication systems consolidate tracking of multiple trigger events into a single counter in place of plural counters. The single counter may track multiple trigger events for a single triggered element. Likewise, the single counter may track trigger events for a plurality of triggered elements. By consolidating tracking of trigger events with reference to a single counter, the size of the circuit may be reduced and power savings may be achieved.

Abstract: Pulse amplitude modulation (PAM) encoding for a communication bus is disclosed. In particular, various two-wire communication buses may encode bits using three-level PAM (PAM-3) or five-level PAM (PAM-5) to increase bit transmission without requiring increases to clock frequencies or adding additional pins. Avoiding increases in clock frequencies helps reduce the risk of electromagnetic interference (EMI), and avoiding use of extra pins avoids cost increases for integrated circuits (ICs).

Abstract: Expanded function datagrams in a system power management interface (SPMI) system allow a slave to use an expanded function datagram to address a larger number of masters (e.g., more than four) associated with the SPMI system. Furthermore, addressing may allow for a datagram to be broadcast to multiple masters concurrently. Still further, by signaling that the master addressing is other than the standard SPMI format, the nature of the address and payload of a datagram may be varied to handle larger volumes of data than the SPMI standard normally allows.

Abstract: Unified systems and methods for interchip and intrachip node communication are disclosed. In one aspect, a single unified low-speed bus is provided that connects each of the chips within a computing device. The chips couple to the bus through a physical layer interface and associated gateway. The gateway includes memory that stores a status table summarizing statuses for every node in the interface fabric. As nodes experience state changes, the nodes provide updates to associated local gateways. The local gateways then message, using a scout message, remote gateways with information relating to the state changes. When a first node is preparing a signal to a second node, the first node checks the status table at the associated local gateway to determine a current status for the second node. Based on the status of the second node, the first node may send the message or take other appropriate action.
