Abstract

The embodiment of the invention provides a signal transmission method and communication equipment. The signal transmission method comprises the steps of determining a sending starting condition of a first reference signal and / or determining a sending stopping condition of the first reference signal according to at least one of historical sending information of the reference signal, interception information of the reference signal, a first triggering condition and a second triggering condition. In the embodiment of the invention, the types of the first reference signals comprise a first type and a second type, and the first reference signals of the first type are used for triggering other communication equipment to execute interference management operation, and the first reference signals of the second type are used for indicating whether the atmospheric waveguide phenomenon disappears or not. Through the first reference signal with the first type and the second type, the communicationequipment can be prevented from executing unnecessary interference management operation, so that the utilization efficiency of network resources can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a signal transmission method and communication equipment. Background technique [0002] see figure 1 , in the inland areas at the turn of spring and summer and summer and autumn, or in the coastal areas in winter, the phenomenon of surface ducting (atmospheric ducting) is prone to occur. When the atmospheric ducting phenomenon occurs, there will be a layer in the troposphere where temperature inversion or water vapor decreases sharply with height, called the ducting layer, and most 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 Evolutio...
