Problems solved by technology

[0004] However, the beams emitted by the CW base station are relatively simple, which cannot reflect the relationship between path loss and signal propagation distance in actual scenarios, and the current evaluation method for path loss and signal propagation distance cannot reflect the actual propagation relationship between the two
Therefore, the accuracy of the signal propagation model determined by the method of building a CW base station to transmit a single beam signal in the prior art is low

Description

technical field [0001] The present application relates to the field of communications, and in particular, to a method and apparatus for determining a signal propagation model. Background technique [0002] When planning the network, it is necessary to rely on the prediction of the signal propagation model to determine the station spacing of the base stations in the target area, and perform network planning and site settings for the target area according to the base station station spacing. [0003] The current signal propagation model is determined by: building a simple continuous wave (CW) base station, the CW base station transmits a single beam signal, and the signal strength of the single beam signal transmitted by the CW base station and the signal of the single beam signal received by the terminal Strength evaluates the relationship between path loss and signal propagation distance to determine a signal propagation model. [0004] However, the beams emitted by CW base...
