Abstract

Embodiments of the present invention provide a signal transmission method and device, the method comprising: sending a first reference signal, the first reference signal indicating: the first network device is subject to far-end interference; receiving a second reference signal, The second reference signal indicates whether the atmospheric ducting phenomenon exists. In the embodiment of the present invention, by using the second reference signal indicating the presence of far-end interference, it can accurately determine whether the factors causing the far-end interference disappear, and effectively avoid the ping-pong effect in the far-end interference processing.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a signal transmission method and device. Background technique [0002] In inland areas at the turn of spring and summer, summer and autumn, or in coastal areas in winter, the phenomenon of surface ducting is prone to occur. Such as figure 1 As shown, when the atmospheric ducting phenomenon occurs, there will be a layer in the troposphere where the temperature inversion or water vapor decreases sharply with height, called the ducting layer, and most of the radio wave radiation will be confined in the ducting layer for super-refractive propagation . Transhorizon propagation allows radio signals to travel great distances with low path propagation losses. [0003] For cellular wireless communication systems (for example: fourth generation mobile communication (forth generation, 4G) long term evolution (Long Term Evolution, LTE) system, or fifth...
