Patent ID: 11259315

Abstract:
Embodiments of the present disclosure provide a data transmission method, a network device, and a terminal device. A network device configures N groups of scheduling information based on a requirement of a terminal device group, configures at least one piece of downlink data based on M groups of scheduling information in the N groups of scheduling information, and sends first downlink data to a first terminal device in a first transmission time unit. Correspondingly, the first terminal device determines the N groups of scheduling information, and detects the first downlink data in the first transmission time unit based on the N groups of scheduling information. In the process, the first downlink data can be successfully transmitted through a plurality of transmissions and one successful detection, thereby implementing highly reliable data transmission. In addition, not only low reliability of PDCCH dynamic scheduling is avoided without introducing a large quantity of control overheads, but also link adaptation can be obtained.
