Abstract

The present disclosure relates to a communication technique for the convergence of IoT technology and a 5G communication system for supporting a higher data transfer rate than a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (e.g., smart homes, smart buildings, smart cities, smart or connected cars, health care, digital education, retail business, and services associated with security and safety) on the basis of 5G communication technology and IoT-related technology. Disclosed is an analysis method and apparatus for performing an analysis procedure for network design at an improved speed while maintaining accuracy and reliability.

First claim

1 . An analysis method for a network design in a wireless communication system, comprising:
obtaining map data for an analytical region; determining a plurality of split regions from the analytical region using the map data; setting a condition for simplified analysis with respect to the plurality of split regions; and performing simplified analysis on each of the plurality of split regions based on the condition.

2 . The analysis method of claim 1 , further comprising performing full analysis on the analytical region when an error between results of the analysis of the plurality of split regions and results based on a previously input analysis condition is less than a threshold.

3 . The analysis method of claim 1 , wherein:
the condition for simplified analysis comprises at least one parameter of ray spacing, reflection, diffraction, or transmission in a ray tracing (RT), and the simplified analysis comprises an RT method having a computation speed improved based on the at least one parameter.

5 . The analysis method of claim 1 , further comprising determining a transmission candidate location and a reception candidate location within the analytical region using the map data,
wherein the transmission candidate location is determined based on information on at least one of a beam width of a transmitter, an installation height of the transmitter, whether a transmitter is to be down tilted, a range of the down tilting of the transmitter, a road width, or a deployment of buildings.

6 . The analysis method of claim 1 , further comprising determining a transmission candidate location and a reception candidate location within the analytical region using the map data,
wherein the reception candidate location is determined based on at least one of information indicative of a local characteristic of the analytical region or information indicative of a deployment scenario of the analytical region.

7 . The analysis method of claim 1 , wherein:
setting the condition for simplified analysis further comprises receiving an input for a value to be compared, the analysis method further comprises:
