A radio transmission power control method and device

Abstract

The invention discloses a radio transmission power control method and a radio transmission power control device. The method comprises the following steps of acquiring radio transmitting power Pti, radio receiving power Pri, interference signal power Iti of a transmitting end, interference signal power Iri of a receiving end and a standard deviation J of shadow fading at the moment ti; obtaining asignal interference ratio Wti of the sending end and a signal interference ratio Wri of the receiving end according to Pti, Pri, Iti, Iri and J; respectively comparing the Wti and the Wri with the signal-to-interference ratio gate limit u; if Wti or / and Wri is / are smaller than u, adjusting the current radio transmitting power of the wireless access point AP, so that the signal interference ratio of the transmitting end to the receiving end is not smaller than u; judging whether the adjusted radio transmitting power Pti'is greater than the minimum power received by other STAs in the current local area network or not, and if so, taking the Pti 'as the radio transmitting power in the transmission time slot of the ti moment by the wireless access point AP; and if not, keeping the radio transmitting power of the wireless access point AP unchanged. According to the invention, radio transmission power self-adaptive control is realized.

Description

Technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a wireless communication transmission power control method and device. Background technique [0002] Thanks to the development of wireless communication technology, more and more wireless communication devices are widely used in various fields. The biggest advantage of wireless communication is to get rid of space constraints. Users only need to use wireless communication equipment, such as mobile phones, Pads, mobile computers, mobile data receiving vehicles, drones and other equipment. STA connects to WiFi routers, wireless communication base stations and other wireless access Point (AccessPoint, AP) can carry out data transmission; at the same time, the shortcomings of wireless communication are also obvious. It is greatly affected by the wireless environment and there is signal interference. At the same time, radio is electromagnetic wave, and there is p...
