coordinated multipoint (CoMP)

Coordinated MultiPoint (CoMP) is a technology designed to improve the performance of cellular networks, particularly at the cell edges, where users experience poor signal quality due to interference from neighboring cells. CoMP achieves this by dynamically coordinating transmission and reception across multiple geographically separated sites. This coordination allows for better utilization of the network by routing data through less loaded base stations, enhancing reception performance through the use of multiple cell sites for each connection, and reducing interference by employing specialized combining techniques that utilize interference constructively rather than destructively[1].

CoMP is particularly significant in the context of 5G networks. It was initially used in LTE Advanced to improve service at the cell edge by utilizing multiple eNodeBs (eNBs), thereby boosting the signal and reducing interference. In 5G, CoMP takes on greater importance due to its ability to deliver capacity gains and latency improvements in small cell environments, making it crucial for enterprise and venue deployments as well as Industrial IoT applications.

CoMP in 5G is sometimes referred to as 'Distributed MIMO' because it combines antennas from multiple small cells to create more spatial dimensions, allowing for simultaneous transmission to multiple users in the same geographical area, thereby increasing system capacity and reliability[1].
