## What is frequency reuse in LTE?

LTE Radio Access LTE is designed to operate with a one-cell frequency reuse, implying that the same time–frequency resources can be used in neighboring cells.

What is the frequency of reuse?

Frequency Reuse is the scheme in which allocation and reuse of channels throughout a coverage region is done. Each cellular base station is allocated a group of radio channels or Frequency sub-bands to be used within a small geographic area known as a cell.

### What is frequency reuse formula?

The frequency reuse factor of a cellular system is 1/N,since each cell within a cluster is assigned 1/N of the total available channels in the system. In this example, N = 19 (i.e., i = 3, j = 2). To find the nearest co-channel neighbours of a particular cell, a. move i cells along any chain of hexagons then, b.

What is the principle of frequency reuse?

Frequency reusing is the concept of using the same radio frequencies within a given area, that are separated by considerable distance, with minimal interference, to establish communication. For example, when N cells are using the same number of frequencies and K be the total number of frequencies used in systems.

## What are the disadvantages of frequency reuse?

Although frequency reuse- m model mitigates ICI, the main disadvantage of such technique is that it reduces network capacity. With less resources available in each cell, the operator is not able to accommodate all the existing UEs.

What are the advantages of frequency reuse?

Frequency Reuse

• Allows communications within cell on a given frequency.
• Limits escaping power to adjacent cells.
• Allows re-use of frequencies in nearby cells.
• Uses same frequency for multiple conversations.
• 10 to 50 frequencies per cell.

### Is the major concern in the frequency reuse?

Co-channel interference is a major concern. The frequency reuse distance, D, (i.e., the distance between the two adjacent co-channel cells of radius R) is related to the number of cells in a frequency reuse pattern K by the following CCI reduction factor: [D/R]2=3K. K-1: frequency reuse efficiency.
