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.
