Abstract

Disclosed are a communication technique of merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security and safety related services, and the like) on the basis of 5G communication technology and an IoT-related technology. According to an embodiment of the present disclosure, a network design method of a wireless communication system comprises the steps of: setting at least one environmental element related to millimeter wave (mmWave) propagation, on the basis of image information within a set map; grouping a design area within the map into at least one detailed area; and designing a network.

First claim

The invention claimed is:

1. A method for network design in a wireless communication system, the method comprising:
configuring at least two environmental factors related to millimeter wave (mmWave) propagation based on image information in a map, wherein the at least two environmental factors include shapes formed by a plurality of buildings, a building layout, a foliage density, and a road shape;
dividing a design region in the map into one or more subregions based on the shapes formed by the plurality of buildings;
grouping the one or more subregions based on states of the at least two environmental factors; and
performing a ray tracing for determining at least one base station position in the design region according to grouped one or more subregions.

2. The method of claim 1 , wherein the at least two environmental factors further include first characteristic information and second characteristic information of the shapes formed by the plurality of buildings.

3. The method of claim 2 , wherein the dividing of the design region in the map comprises:
dividing the design region into first subregions and grouping the first subregions based on the first characteristic information; and
dividing the first subregions into second subregions and grouping the second subregions based on the second characteristic information.

4. The method of claim 3 ,
wherein the design region is divided into the first subregions and the first subregions are grouped according to a first template for a first shape of the shapes formed by the plurality of buildings,
wherein the first subregions are divided into the second subregions and the second subregions are grouped according to a second template for a second shape of the shapes formed by the plurality of buildings,
wherein the first template is determined based on the first characteristic information, and
wherein the second template is determined based on the second characteristic information.

5. The method of claim 1 , wherein the performing of the network design comprises:
identifying characteristics of a signal transmitted from a transmission point to a reception point in the wireless communication system based on the grouped one or more subregions; and
designing a network of the wireless communication system based on the identified characteristics of the signal.

6. The method of claim 1 , wherein the image information is determined based on at least one of two-dimensional map information or three-dimensional map information.

7. A non-transitory storage medium storing a program that includes instructions configured to implement the method of claim 1 .

8. An apparatus for network design in a wireless communication system, the apparatus comprising:
a transceiver configured to transmit and receive information; and
a controller configured to:
configure at least two environmental factors related to millimeter wave propagation based on image information in a map wherein the at least two environmental factors include shapes formed by a plurality of buildings, a building layout, a foliage density, and a road shape,
divide a design region in the map into one or more subregions based on the shapes formed by the plurality of buildings,
group the one or more subregions based on states of the at least two environmental factors, and
perform a ray tracing for determining at least one base station position in the design region according to grouped one or more subregions.

9. The apparatus of claim 8 , wherein the at least one of the two environmental factors further include first characteristic information and second characteristic information of the shapes formed by the plurality of buildings.

10. The apparatus of claim 9 , wherein the controller is further configured to:
divide the design region into first subregions and group the first subregions based on the first characteristic information, and
divide the first subregions into second subregions and group the second subregions based on the second characteristic information.

11. The apparatus of claim 10 ,
wherein the controller is further configured to:
divide the design region into the first subregions and group the first subregions according to a first template for a first shape of the shapes formed by the plurality of buildings, and
divide the first subregions into the second subregions and group the second subregions according to a second template for a second shape of the shapes formed by the plurality of buildings,

wherein the first template is determined based on the first characteristic information, and
wherein the second template is determined based on the second characteristic information.

12. The apparatus of claim 8 , wherein the controller is further configured to:
identify characteristics of a signal transmitted from a transmission point to a reception point in the wireless communication system based on the grouped one or more subregions, and
design a network of the wireless communication system based on the identified characteristics of the signal.

13. The apparatus of claim 8 , wherein the image information is determined based on at least one of two-dimensional map information or three-dimensional map information.
