Abstract

The invention provides a frame format configuration method and device, and the method comprises the steps that terminal equipment receives first configuration information transmitted by a base station, and the first configuration information is used for indicating the transmission time of channel occupancy time (COT) indication information; and the terminal equipment monitors COT indication information at the sending opportunity of the COT indication information, and the COT indication information is used for indicating a COT frame format. The sending opportunity of the COT indication information is configured for the terminal equipment through the base station, so that missed detection of the terminal equipment on the COT indication information caused by signal interference or poor channel quality can be avoided, and meanwhile, the power consumption of the terminal equipment for detecting the COT indication information can be reduced.

Description

technical field [0001] The present application relates to the communication field, and more specifically, relates to a frame format configuration method and device. Background technique [0002] With the development of enhanced mobile broadband (enhanced mobile broadband, eMBB) services, users have increasing demands on wireless network bandwidth and throughput. In order to make better use of license-free spectrum resources and provide end users with higher service rates and better user experience, unlicensed systems are introduced into long term evolution (LTE) and new radio (NR) systems. (un-licensed) access technology. [0003] In the system design of LTE-U and NR-U, the transmission opportunity is obtained through listen before talk (LBT). The transmission opportunity has two dimensions of frequency domain and time domain, and its frequency domain bandwidth is similar to that of LBT. Correspondingly, the acquired transmission time length is called channel occupancy tim...
