Uplink control information transmission method and device

Abstract

The present application discloses an uplink control information transmission method and device. The method includes: determining, by user equipment, a physical uplink control channel (PUCCH) corresponding to uplink control information (UCI); and transmitting, by the user equipment, the UCI on a first PUSCH in a first physical uplink shared channel (PUSCH) set; wherein every PUSCH contained in the first PUSCH set overlaps with the PUCCH in time. In this way, the challenge to the processing capability of the user equipment caused by transmitting the uplink control information on the PUSCHs can be effectively avoided, and meanwhile, the downlink data transmission performance can be ensured.
