Abstract: The present disclosure provides an information processing method and apparatus. A terminal device encodes uplink control information (UCI) to obtain coded bits of the UCI, and encodes data to obtain coded bits of the data. The terminal device multiplexes the coded bits of the UCI and the coded bits of the data to obtain a multiplexed bit sequence. The terminal device then transmits the multiplexed bit sequence to a network device via a physical uplink shared channel (PUSCH). A length of a transmission time interval of the UCI is less than or equal to 0.5 millisecond. In this way, data transmission latency can be reduced.

Abstract: The present invention relates to the communications field, and provides an uplink data sending method and apparatus, so as to adapt to uplink channel sending in a case of a shortened transmission cycle. The method includes: performing, by a terminal, power control depending on whether a time domain resource on which an uplink channel is located carries a reference signal (RS) of the uplink channel; determining first transmission power of a first uplink channel; and sending, by the terminal, the first uplink channel at the first transmission power. The foregoing method improves accuracy of uplink channel demodulation by a base station.
