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.

Abstract: The present disclosure relates to data transmission methods, apparatus, and systems. One example base station includes at least one processor and a transceiver. The at least one processor is configured to determine a data transmission resource, where the data transmission resource includes a time-domain transmission resource and a frequency-domain transmission resource. The transceiver is configured to send downlink control information (DCI) to a terminal device, where the DCI indicates the time-domain transmission resource, and perform data transmission with the terminal device on the data transmission resource.

Abstract: A DCI sending method and an apparatus are provided. A base station determines a first channel resource, where the first channel resource is located in the ith time unit of a subframe in a time domain, the subframe includes NT time units, NT is an integer greater than or equal to 2, and i is a positive integer less than or equal to NT; and the base station sends DCI to a terminal device on the first channel resource. In this solution, the first channel resource that carries the DCI is located in the ith time unit of the subframe in the time domain, where i is a positive integer less than or equal to NT. That is, there is a first channel resource in each time unit of the subframe. Therefore, when data needs to be transmitted in any time unit, the data can be transmitted immediately.

Abstract: Method and apparatus are provided to allocate a time and frequency resource of a resource request indicator (RRI) and to transmit an RRI. Codes are allocated for an RRI and other (such as non-RRI) uplink control signaling. The RRI and other uplink control signaling can be multiplexed in the same time and frequency resource, such as through multiplexing in a code division manner.

Abstract: Embodiments of the present invention disclose a method for detecting a signal on an unlicensed spectrum channel, user equipment, and a base station. The method includes: receiving, by user equipment, instruction information sent by a base station; and starting, by the user equipment according to the instruction information, to detect a signal on an unlicensed spectrum channel. According to the present invention, only when receiving the instruction information sent by the base station, the user equipment detects the signal on the unlicensed spectrum channel according to the instruction information. This reduces power consumption of the user equipment.
