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.

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.
