In LTE (Long Term Evolution), the IRC (Rejection Combination Rejection) feature is designed to mitigate interference from neighboring cells in the process of receiving downlinks. LTE networks are structured with cells that reuse the same frequencies in different geographic areas to maximize spectrum efficiency. However, this can lead to interference between adjacent cells, affecting the quality of the received signal.
IRC helps improve the signal-to-interference-plus-noise ratio (SINR) by combining multiple signals received from different antennas or different time instances, effectively reducing the impact of interference from neighboring cells and improving the overall throughput of data and reliability in LTE networks in LTE networks.
Inter-cell interference in LTE refers to the interference caused by signals transmitted from neighboring cells operating on the same frequency resources.
LTE networks use frequency reuse strategies where adjacent cells use overlapping frequency bands to maximize spectrum usage. However, this can lead to interference between cells, especially at cell edges or overlapping areas where signals from different cells interfere with each other. Inter-cell interference can degrade signal quality, reduce data throughput, and impact overall network performance.
Techniques such as interference coordination, power control, and advanced antenna technologies are used to mitigate inter-cell interference and optimize LTE network performance.
Uplink interference in LTE occurs when signals transmitted from mobile devices to the base station are affected by interference sources in the same or nearby cells. In LTE Networks, the uplink transmission of mobile devices operates in frequency bands allocated for uplink communication.
Interference in the uplink can come from neighboring cells using the same or adjacent frequency bands, causing signal degradation and reducing the reliability of data transmission from mobile devices to the base station. Techniques such as interference cancellation, power control and scheduling algorithms are used in LTE networks to minimize uplink interference and improve uplink communication efficiency, ensure reliable connectivity and data rate for mobile users
