Unlicensed spectrum edge access and anti-interference method and device for cooperative terminal communication

Abstract

The invention provides an unlicensed spectrum edge access and anti-interference method and device for cooperative terminal communication, electronic equipment and a readable storage medium. The methodcomprises the following steps: receiving unauthorized channel detection results sent by a plurality of IoT devices through a base station, determining an unauthorized channel corresponding to the minimum interference intensity as a target unauthorized channel, dividing the target unauthorized channel into a plurality of sub-channels, and selecting K IoT devices with the minimum interference and all cellular user terminals as relay nodes, and optimizing the number of the IoT devices scheduled in the network through an iterative algorithm to obtain a device scheduling scheme. The unlicensed channel corresponding to the minimum interference intensity is selected to be determined as the target unlicensed channel for the IoT devices to perform data transmission, the licensed spectrum and the unlicensed spectrum can be used for data transmission at the same time, the coverage range of the network is expanded, the number of the IoT devices scheduled in the network is optimized through an iterative algorithm, and the user experience is improved, so limited spectrum resources are reasonably utilized so as to increase the number of accessed IoT devices.

Problems solved by technology

[0002] With the development of the fifth-generation communication technology, more and more application scenarios need to support large-scale IoT devices. As the edge nodes of the network, these devices are faced with the shortage of licensed spectrum and insufficient bandwidth, which cannot meet the needs of large-scale data transmission. needs

[0003] In related technologies, such as Narrowband Internet of Things technology (NB-IoT), the use of narrowband licensed spectrum can reduce power consumption while ensuring service quality. IoT device deployment

[0004] The existing unlicensed spectrum access technology only considers that IoT devices directly upload data to the base station in one of the ways of machine-to-machine connection and communication or cellular communication, and cannot use multiple communication methods for data transmission. The overall utilization rate of resources is low, the network coverage is small, and it cannot support large-scale device access
