UPLINK CONTROL INFORMATION TRANSMISSION METHOD AND DEVICE

WIPO Patent Application WO/2019/128386

A1

Disclosed is an uplink control information transmission method and device, which are used to implement simultaneous transmission of HARQ-ACK (Hybrid Automatic Retransmission Quest-Acknowledgement) feedback information and SR (Scheduling Request) information when the HARQ-ACK feedback information and the SR information are configured with different NR PUCCH (Physical Uplink Control Channel) formats, so as to ensure that a network side can acquire the HARQ feedback information and the SR information in time. The method includes: determining that the following conditions are met: the HARQ-ACK feedback information is configured to be transmitted by using a first channel format; the SR information is configured to be transmitted by using a second channel format; transmission time domain resources of the SR information overlaps with transmission time domain resources of the feedback information; when the SR information is positive SR information, transmitting the HARQ-ACK feedback information on the transmission resources of the SR information by using the second channel format; and when the SR information is negative SR information, transmitting the feedback information on the transmission resources of the HARQ-ACK feedback information by using the first channel format.
