Abstract: The present disclosure relates to methods for obtaining channel state information (CSI), apparatus, and computer storage medium. One example method includes allocating, by a network device to a terminal device according to a preset rule, a transmission resource for transmitting a sounding reference signal (SRS) in a cell to which the terminal device belongs. Transmission resources for transmitting SRSs in different cells do not overlap at all or partially overlap. The network device receives the SRS transmitted by the terminal device on the allocated transmission resource, and performs channel quality estimation based on the received SRS to obtain CSI.

Abstract: A method may involve sending signals with a frequency modulated continuous wave radar, receiving the signals reflected at the radar, and processing the received signals into point cloud data having a plurality of points. The method may involve assigning the plurality of points to a track and determining track information based on the plurality of points assigned to the track. The method may involve comparing track information against debounce criteria, where track information may be flagged as dynamic clutter by using a Kalman filter based algorithm on the track information. The method may include calculating a velocity of the vehicle based on the flagged track information. The method may change an operation of the vehicle in response to the calculated velocity of the vehicle.

Abstract: Each signal channel has a 12 bit A/D converter which begins conversion after each read cycle. A 24 bit digital signal processor is connected by a 24 bit data bus to the converters such that one converter supplies data to the upper data lines and the other supplies data to the lower data lines of the bus. Both converters are simultaneously read into the processor, the data being combined into one word. The processor then splits the word into separate data for each channel by multiply and move operations.

Abstract: A method and system for discriminating a target which presents a hazard to a motor vehicle moving in a first lane of traffic from a target moving in a second adjacent lane of traffic which does not present a hazard to the vehicle. The method includes the steps of utilizing an antenna mounted flush to a side of the vehicle to produce a radar beam having a beamwidth greater than 5-10 degrees to illuminate the target. At least a portion of the radar beam is produced along a first axis which is perpendicular to the direction of motion of the vehicle. The reflected signal is received from the illuminated target and a velocity of the illuminated target is estimated with a Kalman filter relative to the velocity of the vehicle in the direction of a second axis which is parallel to the direction of motion of the vehicle based on the reflected signal.
