Abstract: A method of a vehicle obtaining sensor data originating at one or more of other vehicles includes receiving input from an operator or system within the vehicle, and generating a request for the sensor data based on the input. The request specifies one or more parameters and the one or more parameters include a location at which the sensor data is obtained. The method also includes sending the request for the sensor data, receiving the sensor data, and processing the sensor data. The processing includes providing the sensor data to the operator or the system within the vehicle based on the input. A central server includes an interface to receive sensor data and parameters from one or more vehicles according to vehicle-to-network (V2N) communication. A processor generates a digital map from the sensor data. The digital map includes a layer for each type of the sensor data.

Abstract: The present application generally relates communications and hazard avoidance within a monitored driving environment. More specifically, the application teaches a mechanism to monitor, identify and locating vulnerable road users in a hazard situation by receiving location and vector information from road users in an environment, determining the probability of a hazard situation arising in response to the location and vector information, and transmitting data to one or more road users in order to avoid the hazard situation.

Abstract: An autonomous-driving vehicle system, for implementation at an autonomous-driving vehicle. The autonomous-driving vehicle system includes a hardware-based processing unit and a non-transitory computer-readable storage device comprising and input module and an activity module.

When the base coil is tuned to the receiver coil the power source can be recharged through magnetic resonance coupling to power the device. The transmitter circuit can be on the vehicle or can be separate from the vehicle, such as in a charging pad.

Abstract: A method and system to increase the throughput of a HARQ protocol in a wireless network. When a station receives a downlink HARQ sub-burst that has an incorrect cyclic redundancy check, it determines if there is an overflow event of its buffer. If so, the station reduces the size of the HARQ sub-burst to be stored in the buffer and stores the resized HARQ sub-burst in the buffer. When the station transmits an uplink HARQ sub-burst, the station can reduce the size of the transmitted HARQ sub-burst if it exceeds the size of the buffer. The amount of buffer required in the station can also be reduced by representing each log likelihood ratio (LLR) value of each of one or more bits of each symbol of a HARQ burst with a number of quantization bits based on a metric sensitivity to noise of each bit of each symbol.

Abstract: In some embodiments, the invention involves increasing hybrid automatic repeat request (HARQ) throughput. In one embodiment, throughput may be increased by clearing the retransmission buffer at least one frame in advance, based on status received from the downlink device before a full acknowledgement. Another embodiment partitions HARQ bursts into two groups. A first group is for packet data units (PDUs) that are anticipated to be in error and a second group is for PDUs anticipated to be received correctly. Only PDUs that are anticipated to be in error, based on forward error correction (FEC) blocks, are to be saved in the retransmission buffer. Other embodiments are described and claimed.

Abstract: All practical communication channels impose some type of corruption on received data through inter-symbol interference (ISI). ISI corruption is particularly acute in high-order constellation transmission. Although ISI effects of high-order constellation transmission are very large on average, some symbols may be received that suffer relatively low levels of ISI. These symbols are “reliable symbols” and can be used to provide blind estimation of the ISI coefficients. Once the ISI effects of a channel are known, all captured signals may be corrected.

Abstract: A fast equalization technique is disclosed for systems using high-order constellations where symbols have been corrupted by data correlated noise (ISI). The technique permits ISI estimation to begin immediately upon receipt of captured samples. Training symbols are not required for the operation of the equalization technique. ISI estimation is weighted in accordance to a reliability factor of each captured sample.
