Description

Method and apparatus for cooperation of multiple reading devices used for wireless communication Technical Field The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a method and apparatus for cooperative paging between a plurality of reading devices. Background Along with the continuous development of wireless communication, the low-power consumption requirement on wireless access equipment is higher and higher, and particularly, the Internet of things is more and more concerned in the field of wireless communication, and the number of the equipment of the Internet of things is huge, so that batteries needing to be manually replaced or charged can cause high maintenance cost, serious environmental problems and even potential safety hazards. The 3GPP (the 3rd Generation Partnership Project, third generation partnership project) Release19 establishes a "NR (New Radio, new air interface) environment internet of things (Ambient Internet of Things, a-IoT) solution research" Study Item (SI) for evaluation of the internet of things deployed in the 3GPP system, including paging mechanisms and flow design. Disclosure of Invention The inventor found through research that if one a-IoT device supports only one reading device, there may be a situation that the a-IoT device cannot be paged because the a-IoT device is not in the coverage area of the reading device, the problem may be effectively solved by one a-IoT device supporting receiving multiple reading devices, further, if one a-IoT device supports receiving multiple reading devices, how to configure multiple reading devices and how to coordinate between multiple reading devices is a necessary problem, including but not limited to how to prevent occupation conflict of paging resources, and/or how to resend paging messages, and/or how to improve flexibility of paging, etc. The present application provides a solution to the above problems. In the description of the above problems, although the present application provides a specific implementation manner for an a-IoT device, the present application can also be used in other IoT or terminal scenarios, and achieve technical effects similar to those of the a-IoT device. Furthermore, the adoption of a unified design scheme for different scenes also helps to reduce hardware complexity and cost. As an embodiment, the explanation of the terms in the present application refers to the definition of the 3GPP specification protocol TS38 series. It should be noted that, in the case of no conflict, the embodiments of any node of the present application and the features in the embodiments may be applied to any other node.

When a certain coverage is exceeded, another reading device within the coverage may need to be informed to send a paging message in order to wake up the device successfully. How to notify another reading device is a problem to be considered, and therefore, it is necessary to consider a mechanism of cooperatively transmitting a paging message between a plurality of reading devices in order to page the devices more flexibly. The above method solves the above problem by interacting at least the first assistance information to cause another reading device to send a first paging message. The method is beneficial to control of the network side. The method is beneficial to improving the paging success rate.
