Abstract: The present disclosure provides a switching current source circuit and a method for quickly establishing a switching current source. The switching current source circuit includes a first and a second switching current source branches connected in parallel with one end of a load. When the switching enable signal is switched, due to the charge coupling of the first and second switching current source branches, the bias voltage respectively generates bounce in the same direction as and a direction opposite to the transition direction of the switching enable signal. The two bounces cancel each other to make the current source bias voltage recover quickly when a toggle event happens. The present disclosure accelerates the establishment of current through the coupling of charges, and reduces the decoupling capacitance at the same time, thereby reducing the circuit area and saving the costs.

Sensor data indicative of one or more targets from an imaging and ranging subsystem, location data from a positioning subsystem defining a geographical location of the imaging and ranging subsystem and orientation data from an orientation subsystem defining an orientation of the imaging and ranging subsystem are received. Doppler point cloud data is generated based on Doppler information and point cloud data from the sensor data, the location data and the orientation data. The targets are classified as either a static or dynamic target. Afterwards, the Doppler point cloud data is filtered by removing either the dynamic or the static targets from the Doppler point cloud data. The Doppler point cloud data of either the dynamic or the static targets are further processed and the further processed Doppler point cloud data is rendered.

Abstract: In a demodulation reference signal (DMRS) configuration method, a network device sends first scheduling information to a terminal device. The terminal device determines, based on the first scheduling information, whether a transmission of a first time unit meets a condition of having the same transmit power, same precoding, same antenna port, or a same frequency domain resource as the transmission of a second time unit. The second time unit is before the first time unit and has a transmission direction that is the same as a transmission direction in the in the first time unit, and no transmission in an opposite direction exists between the second time unit and the first time unit. When the first time unit meets the above condition, the terminal device sends uplink data in the first time unit and the second time unit, or receiving downlink data in the first time unit and the second time unit.
