Technique for coordinating transmission/reception across multiple cell sites to improve performance.
Description
Coordinated Multi-Point (CoMP) is a family of techniques where transmission and/or reception at multiple geographically separated points is coordinated to improve system performance, especially at cell edges.
CoMP includes Joint Transmission (JT) where multiple points transmit simultaneously, Dynamic Point Selection (DPS) where the best transmission point is selected dynamically, and Coordinated Scheduling/Beamforming (CS/CB) where interference is managed through coordination.
For uplink, CoMP reception combines signals received at multiple points.
Purpose & Motivation
CoMP was introduced to:
- Improve cell-edge user throughput - Reduce inter-cell interference - Increase overall system capacity - Enable efficient utilization of distributed antenna systems
