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, device, electronic equipment and readable storage medium for cooperative terminal communication. Receive the unlicensed channel detection results sent by multiple IoT devices through the base station, determine the unlicensed channel corresponding to the minimum interference intensity as the target unlicensed channel, divide the target unlicensed channel into multiple sub-channels, and select the least interfered K An IoT device and all cellular user terminals are used as relay nodes, and the number of IoT devices scheduled in the network is optimized through an iterative algorithm to obtain a device scheduling scheme. By selecting the unlicensed channel corresponding to the minimum interference intensity as the target unlicensed channel for IoT device data transmission, the licensed spectrum and unlicensed spectrum can be used for data transmission at the same time, which expands the coverage of the network and optimizes the network through iterative algorithms The number of IoT devices scheduled in the network can make reasonable use of limited spectrum resources to increase the number of connected IoT devices.

Description

Technical field [0001] The present invention relates to the field of communication technology, and more particularly to a non-authorized spectral edge access and anti-interference method and apparatus for cooperating terminal communication. Background technique [0002] With the development of the fifth-generation communication technology, more and more application scenarios need to support large-scale IOT equipment, as the edge node of the network, facing the issue of lack of spectrum shortage and insufficient bandwidth, unable to meet large-scale data transmission Need. [0003] In the related art, such as narrowband IoT technology (NB-IOT), with narrowband authorization spectrum, it can reduce power consumption in the case of ensuring service quality, this technology is applied to authorization spectrum, which cannot meet large-scale in the hot area. IOT equipment deployment. [0004] Existing unauthorized spectrum access technology only considers that the IOT device is direct...

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
