Title:
CONTROL CHANNEL TRANSMISSION METHOD AND APPARATUS, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/007759
Kind Code:
A1
Abstract:
The embodiments of the present application provide a control channel transmission method and apparatus, and a storage medium. A network device determines a first search space set within a channel occupancy time (COT) of a fixed frame period, and when it is determined that resources in the COT can be used, sends a first PDCCH in the first search space set, wherein the first PDCCH is used to transmit time slot structure indication information, and the time slot structure indication information is used to determine the time slot structure of the COT. When it is determined that the resources within the COT cannot be used, no downlink channel or no downlink signal is transmitted within the COT. Correspondingly, after a terminal device determines the first search space set within the COT of the fixed frame period, the first PDCCH is monitored according to the first search space set, thereby determining whether time slot structure indication information for determining the time slot structure of the COT can be acquired. The present invention is able to assist, to a certain extent, the detection of downlink control information, avoiding the problem of resource waste caused by long-time detection.
