Management of external interference from all other sites/sectors improves system performance and capacity. Intervention studies are used to examine areas that have significant peripheral interaction problems. Lighting and intervention studies are analysis to determine what sites/sectors of intervention problem (i.e. determining what sites/sectors may be providing too much interference in the field or sites/sectors that do not provide adequate coverage to overcome interference from surrounding sites/sectors).
There are three main methods that can be used to reduce the peripheral intervention in the area. The purpose of these methods is either to increase the signal force of the best serving the site/sector, reducing the signal strength from preventing site/Sector (s), or a combination of both. Several methods to minimize the intervention are as follows:
• Using down-tilt base station antennas to reduce the amount of coverage overlap with adjoining sites and sectors. This will reduce the number of covered area, are experiencing slow CINR.
• Use the 1 x 3 x 3 block group resource reuse sub-pattern to reduce the incidence of peripheral interventions along the borders of the site slightly to boot.
• Selecting a different deployment site layout is better aligned with the 1 x 3 x 1 site posting template reuse.
Methods to Reduce Co-channel Interference in LTE
To reduce co-channel interference in LTE, several techniques are employed. One common method is power control, where the base station adjusts the power levels of transmissions to reduce interference between cells. Another approach is frequency planning, which ensures that neighboring cells do not use the same frequencies. Additionally, advanced antenna techniques, like beamforming, direct signals more precisely, minimizing interference. Dynamic scheduling and interference coordination also help by allocating resources intelligently, reducing the impact of co-channel interference on network performance.
