Abstract

The invention provides a signal transmission method, equipment and device. The method comprises the following steps: determining measured values of positions of a terminal at a current moment and the previous moment in a three-dimensional cell environment, wherein the three-dimensional cell environment is a three-dimensional model constructed based on a detection perception mode; predicting a predicted value of a position at the next moment according to the measured values, and obtaining a beam / scheduling information / a modulation and coding strategy (MCS) which is determined to be adopted according to the three-dimensional cell environment model and the predicted value of the position; and adopting the beam to perform beamforming / adopting the scheduling information to perform scheduling / adopting the MCS to perform modulation, and then performing signal transmission. By using the method provided by the invention, rapid beam tracking of a narrow beam can be realized or UE can be more accurately scheduled in a mobile scene, and low-delay and high-reliability transmission of business is ensured.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a signal transmission method, equipment and device. Background technique [0002] The current 5G NR (New Radio, new air interface) system supports communication in the millimeter-wave frequency band. Base stations / terminals often need to use beamforming technology to form narrow beams and concentrate radiation in a smaller space area, so that the energy on the radio frequency transmission link Higher efficiency, reducing base station / terminal transmission power loss; and in the IMT (International Mobile TelecomSystem, International Mobile Communication System)-2030 system will support terahertz frequency band (0.1 ~ 10THz) communication, base station / terminal will use higher gain Antennas, and integrating more antennas and using beamforming technology to form "pencil-shaped" ultra-narrow beams to overcome the high path loss in the terahertz frequency band to improve...
