Title:
INFORMATION TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/051488
Kind Code:
A1
Abstract:
The present application relates to the technical field of wireless communications. Provided are an information transmission method and apparatus, which are used for improving the sensing or ranging performance. The present application is applied to a wireless personal area network system based on ultra wideband (UWB), which system comprises 802.15 series protocols, such as 802.15.4a, 802.15.4z or 802.15.4ab; and can also be applied to a wireless local area network system that supports 802.11 series protocols, such as the next-generation WiFi protocol of IEEE 802.11ax, for example, 802.11be or EHT, and the next-generation WiFi protocol of 802.11be, for example, WiFi 8, a sensing system, etc. The method comprises: a first device sending first information to a second device to indicate a duration range; and the first device sending second information to the second device to indicate at least two time units, wherein the duration between the end time of a first time unit and the start time of a second time unit is within the duration range.
