LTE technology-based resource allocation method for uplink of internet of things

Abstract

The invention relates to an LTE technology-based resource allocation method for the uplink of an internet of things. The invention provides a solution for realizing the internet of things based on the LTE technology and also provides an allocation method for uplink resources based on QoS. In the resource-poor condition, resources are allocated to delay-sensitive users preferentially, so that the bandwidth requirements of the above users are met. In the resource-rich condition, resources are allocated to users as required according to the actual requirements of the users. On the basis that the QoS is met, the resource utilization rate of the system is maximized.

Description

technical field [0001] The invention relates to a resource allocation method in the wireless communication field, in particular to an uplink resource allocation method using LTE as a backhaul network. Background technique [0002] With the development of intelligent perception, identification technology and wireless communication technology, the concept of the connection of things has gradually become popular, and the Internet of Things is also known as the third wave of the development of the world's information industry after computers and the Internet. However, the current Internet of Things only connects many physical objects, which can communicate with each other, exchange data, and realize various monitoring and control functions. Most of these networks are oriented to specific needs and use dedicated protocols to solve the current concerns of various network owners. . The realization of large-scale interconnection of things is still a trend in the development of the ...

Problems solved by technology

The Internet of Things communication has the following characteristics: 1. The number of user terminals in the Internet of Things is very large, and some terminal nodes cannot directly communicate with eNB due to the limitation of power supply and communication modules; 2. The amount of data transmitted by a single sensing node is generally relatively large. Small, small data transmission often leads to low utilization of wireless resources, and it is proposed to use gateway nodes to collect information from sensing nodes and forward them, thereby improving system utilization; 3. LTE defines 1-9 different classifications Business (referred to as QCI), but for IoT applications, too many classifications will reduce the performance of the system
