Power control method, system and device based on communication network and storage medium

Abstract

The invention provides a power control method, system and device based on a communication network and a storage medium, and the method comprises the steps: obtaining the transmitting signal intensityand / or a power adjustment signal of a central node, wherein the power adjustment signal comprises a power adjustment step length obtained based on the packet error rate of equipment; and obtaining thetransmitting power of the equipment based on the transmitting signal strength and / or the power adjusting signal of the central node. According to the method provided by the invention, an open-loop and closed-loop power control method is introduced on the basis of a communication network, so that the power is further reduced, the purpose of saving more power is achieved, and the packet error rateof data communication can be effectively reduced.

Description

technical field [0001] The present invention relates to the field of communications, and more particularly to power control. Background technique [0002] With the development of the Internet of Things, low-speed, low-power wireless LAN communication technology has been more and more applied. Among them, the IEEE 802.15 working group defined the 802.15.4 technical standard in 2003, which defines the low-speed wireless personal network (LR-WPAN) physical layer (PHY) data link layer (MAC). 802.15.4-based communication technologies such as Zigbee and Thread are widely used in scenarios such as sensor networks and smart homes. [0003] Different from 3GPP wireless communication technologies such as UMTS and LTE, in the 802.15.4 standard, there is no power control-related process defined at the MAC layer. In order to achieve the ideal transmission distance, the device generally uses a large fixed transmission power. For applications that require real-time communication, frequen...

Problems solved by technology

[0003] Different from 3GPP wireless communication technologies such as UMTS and LTE, in the 802.15.4 standard, there is no power control-related process defined at the MAC layer. In order to achieve the ideal transmission distance, the device generally uses a large fixed transmission power. For applications that have certain requirements for real-time communication, it is necessary to send heartbeat (Polling) messages frequently. If a relatively large transmission power is used fixedly, it will have a negative impact on the power consumption of the device.

[0004] Therefore, in the prior art, there are problems of high power consumption and high packet error rate of the equipment in the communication network, which reduces the reliability of the equipment.
