Problems solved by technology

[0004] Based on the data transmission in the scheduling mode, the repeated transmission may be applied to the downlink control channel (Physical Downlink Control channel, PDCCH) and the downlink traffic channel (Physical Downlink Shared channel, PDSCH) at the same time. The initial transmission time indication is difficult to flexibly control the indication and control the time interval and delay of the repeated transmission process, resulting in excessive overall delay and affecting user experience

Embodiment 1

[0028] In view of the fact that in the current repeated transmission scheme, it is difficult to realize the reception of preemption instructions and scheduled downlink traffic channels in advance for the initial transmission time of the repeated transmission of the downlink control channel, it is necessary to consider the problem of not being able to guarantee low-latency transmission requirements on the basis of repeated transmission. In the repeated transmission method provided by this embodiment, the traffic channel for repeated transmission is scheduled through the physical downlink control channel PDCCH, wherein the interval between the PDCCH and the traffic channel is a scheduling timing interval, and the scheduling timing interval includes a value less than or equal to zero Integer, the traffic channel can be a physical downlink traffic channel PDSCH, or a physical uplink traffic channel PUSCH. The following embodiments take PDSCH as an example to illustrate the setting c...

Abstract

The embodiment of the invention provides a repeated transmission method and device, communication equipment and a storage medium. According to the method, a repeatedly transmitted service channel is scheduled through a physical downlink control channel (PDCCH), and a scheduling timing interval is optimized and is set as a negative value, so that the reliability is improved by using repeated transmission, the low-delay transmission effect is ensured, and the low-delay and high-reliability communication requirement is met. Besides, by setting the scheduling timing interval negative number, the repeated transmission scheduling of the PDSCH is indicated in advance, the processing time delay of the terminal is reduced, and the low-time-delay and high-reliability transmission is ensured.
