Description

A method and apparatus in a node for internet of things communication in wireless communication

[0001] This application claims priority from the Chinese patent application No. 202411375029.8 filed on September 29, 2024, and entitled "A method and apparatus in a node for internet of things communication in wireless communication", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to a transmission method and apparatus in a wireless communication system, and in particular to a scheme and apparatus for time domain configuration of signals in wireless communication. BACKGROUND

[0003] The application scenarios of future wireless communication systems are increasingly diversified, and different application scenarios put forward different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, the study of New Radio (NR) (or 5G) was started at the 72nd plenary meeting of 3GPP (3rd Generation Partnership Project) RAN (Radio Access Network). With the wide application of 5G, new business models and new application scenarios are emerging, such as Ambient Internet of Things. The existing 5G standard cannot fully meet the new requirements, so 3GPP is preparing to start the related preliminary study. SUMMARY

[0004] 5G NR system started the research work of Ambient Internet of Things (A-IoT) in Rel-19. In the Ambient Physical Network, OOK is expected to be used for transmission between the reader and the Internet of Things device, as well as between the Internet of Things device and the reader. This research has just begun. The applicant believes that through research, Ambient Internet of Things will also become an important part of future 6G networks. At the same time, the applicant found through research that in the Ambient Physical Network, using the time unit of OOK as the time domain resource unit needs to be compatible with the existing 5G NR system.

[0005] Aiming at the time domain interval problem between control information and data information of signals using OOK in the future, a solution is disclosed in the present application. It should be noted that in the description of the present application, the transmission from the reader to the Internet of Things device is only taken as a typical application scenario or example; the present application is also applicable to 6G networks or other scenarios facing similar problems in the future (for example, there are scenarios that need to consider the processing delay of OOK, or scenarios of conversion between channels using OOK, such as scenarios supporting energy saving, or scenarios supporting user equipment to user equipment transmission, or for different application scenarios, such as eMBB, URLLC, full-duplex network, non-terrestrial network, integrated sensing network, intelligent metasurface, terahertz network, V2X, and similar technical effects can be achieved. In addition, adopting a unified solution for different scenarios (including but not limited to eMBB, URLLC, energy saving, Internet of Things, full-duplex network, non-terrestrial network, integrated sensing network, intelligent metasurface, terahertz network, V2X scenarios) or different application parameters also helps to reduce hardware complexity and cost.
