Abstract

The embodiments of the present application disclose a DCI transmission method and device, a communication device, and a storage medium. The DCI transmission method may include: sending a first DCI, wherein the first DCI includes: a first information domain and a second information domain; the first information domain includes first indication information and second indication information; whereinthe first indication information is used to indicate a successful uplink transmission or a failed uplink transmission; the second indication information is used to indicate that the second informationfield carries new transmission scheduling information or transmission parameter adjustment information when the uplink transmission is successful; the second indication information is further used toindicate that the second information field carries retransmission scheduling information or access indication information when the uplink transmission fails.

Description

technical field [0001] The embodiments of the present application relate to but not limited to the technical field of wireless communication, and in particular, relate to a downlink control information (Downlink Control Information, DCI) transmission method and device, communication equipment, and storage medium. Background technique [0002] In recent years, the rapid development of the Internet of Things has brought many conveniences to human life and work. Among them, machine type communication (Machine type communication, MTC) technology and narrow-band Internet of things (Narrow-band Internet of things, NB-IoT) technology are typical representatives of cellular Internet of things technology. At present, these technologies have been widely used in smart cities, such as meter reading; smart agriculture, such as the collection of information such as temperature and humidity; smart transportation, such as shared bicycles and many other fields. [0003] Since most MTC devic...
