The co- channel interference can be reduced by using directional antennas. This means, division of each cell into three or six sectors and the use of three or six directional antennas at a base station.

What are the ways to reduce co-channel interference?
Decreasing the base station transmitter-receiver power can reduce co-channel interference. If co-channel interference in mobile communication is reduced, it can mitigate crosstalk as well. The use of directional antennas at the base station eliminates co-channel interference.
Which technique is used to increase the system capacity and reduce co-channel interference?
Cell sectoring
The technique for decreasing co-channel interference and thus increasing system performance by using directional antennas is called sectoring.
What is the main cause of co-channel interference?
1.3.
In wireless networks, co-channel interference is caused by the necessary frequency re-use. With multiple antennas, it is possible to exploit the difference between the spatial signatures of the desired vs. the interfering channels to reduce the interference.
How can interference be reduced in cellular system?
A number of techniques have been proposed for mitigating interference in cellular networks. Common methods include; power control, effective frequency assignment using intelligent techniques and intermodulation solutions. Several authors have addressed the problems of interference in the wireless networks.
