Title:
UPLINK INFORMATION TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/137467
Kind Code:
A1
Abstract:
An uplink information transmission method and apparatus, for use in solving the problem in the prior art of being unable to meet the high transmission reliability requirement of URLLC uplink data during transmission of UCI piggyback on PUSCH. The uplink information transmission method comprises: a terminal device receives downlink control information (DCI) sent by a network device, and determines, according to the DCI, a transmission resource of a physical uplink shared channel (PUSCH) scheduled by the DCI, the transmission resource of the PUSCH overlapping a transmission resource of a physical uplink control channel (PUCCH) in time domain, and the PUCCH being used for carrying uplink control information (UCI) to be transmitted; when a first condition is met, the terminal device sends uplink data on the PUSCH, and does not send the UCI on the PUSCH. Thus, reduction of transmission reliability of uplink data caused by UCI piggyback on PUSCH is avoided.
