  • Publication number: 20210204276
    Abstract: This application provides a UCI sending and receiving method and a communications apparatus. In the method, an association relationship between a PUCCH and a PUSCH is established, so that when resources of the PUSCH and the PUCCH overlap, a terminal device can determine UCI on which PUCCHs can be transmitted by multiplexing the resource of the PUSCH. A network device may receive the UCI on the PUSCH. Because the network device may know in advance which PUCCHs and PUSCHs are sent to the network device, the network device can demodulate and decode a signal on the received PUSCHs, to successfully obtain UCI. The network device can make a proper decision based on the UCI.

  • Publication number: 20210203344
    Abstract: The present disclosure provides a voltage-to-time converter and method for reducing parasitic capacitance and power supply influences. The voltage-to-time converter includes: a main sampling network, a compensation sampling network, a discharge network and an over-threshold detection unit. The influence of a traditional VTC parasitic capacitance on a VTC output swing amplitude is reduced by using the compensation sampling network. A sampling common-mode level of the compensation sampling network is compensated, such that the influence of the low-frequency disturbance of a power supply voltage on a threshold of a traditional VTC threshold detection circuit is reduced. The output swing amplitude of the voltage-to-time converter of the present disclosure can reduce the influence of a parasitic capacitance. A voltage common-mode level of a VTC input end is related to a power supply voltage, which reduces a conversion error caused by the influence of the power supply voltage on a threshold.
