Executive Summary
Resource Management with Interference Pre-cancellation (RMIP) mitigates signal interference in a cellular network before it reaches the mobile device. This new technique improves the quality of network service while increasing the data transfer rate.
Description of Technology
Mobile station (MS) signal interference has increased with the expansion of heterogeneous cellular networks (HetNet). Conventional technologies used to resolve signal interference slows data transfer rates and depletes battery life. MSU researchers have developed an algorithm to decrease inter-cell interference while improving data transfer rates and battery life. This method uses the C-RAN infrastructure to identify the towers within the mobile device’s disruption range and sends out a pre-cancelled signal to nullify the interference.
Key Benefits
- No battery consumption
- Reduces inter-cell interference
- Increased data transfer to 21.42 %
- Legacy usage; works with current mobile devices
Applications
- Markets on C-RAN (e.g. China)
- Major cellular networks
- Small cellular networks
