What is CoMP and list the benefits of CoMP?

Coordinated Multi-Point transmission/reception (CoMP) is a technique which utilizes more than one Base Station (BS) to enable communication. Using this, nodes dynamically coordinate transmission/reception of signals from UE to multiple BSs. This increases radio performance specially at cell edge by leveraging inter-cell interference. The concept is used in wireless technologies such as LTE Advanced.

What are the categories of CoMP?

1. Joint Processing: There is coordination between multiple gNBs to transmit/receive signals simultaneously to or from UE.
2. Coordinated Scheduling/Beamforming: Signals are concentrated in one direction towards specific receiver. It increases strength of signals to be transmitted and hence increases chances of their reception at the receiver. This reduces interference from other radio devices and improves the efficiency.

What are the benefits of CoMP?

• It helps service providers by improving network resource utilization i.e. spectrum efficiency.
• It improves QoS (Quality of Service) to the user as there are fewers call drops.
• Subscriber notices higher bandwidth due to service provided by multiple eNBs (i.e. Base Stations) at any given time.
• It reduces the impact of interference. CoMP utilizes interference constructively.
• It improves cell edge throughput and system throughput.
• It improves coverage of the high data rate.
• It improves the overall capacity of the network.
