PHASE SHIFTS FOR IMPROVING COMMUNICATION VIA COVERAGE ENHANCING DEVICES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18283355 titled 'PHASE SHIFTS FOR IMPROVING COMMUNICATION VIA COVERAGE ENHANCING DEVICES
Simplified Explanation
- Method for operating a communication node (CN) controlling a reconfigurable spatial filtering device (CED) - CN receives reference signal from another CN on a radio channel via multiple propagation paths - CN measures reception property of reference signal and configures CED to induce phase shift in propagation path - Innovation involves reconfigurable CED for spatial filtering of incident signals on a radio channel
Potential Applications
- Wireless communication systems - Beamforming technology - Signal processing in radio channels
Problems Solved
- Improving signal reception quality - Enhancing communication efficiency - Minimizing interference in radio channels
Benefits
- Increased signal reliability - Better communication performance - Enhanced network capacity
Original Abstract Submitted
According to a first aspect, examples provide a method of operating a first communication node (CN), wherein the first CN is configured for controlling a first CED, wherein the first CED is reconfigurable to provide multiple spatial filterings, each one of the multiple spatial filtering being associated with a respective input spatial direction from which incident signals on a radio channel are accepted and with a respective output spatial direction into which the incident signals are transmitted by the first CED. The method comprises receiving, from a second CN on the radio channel, a first reference signal via a first propagation path and a second propagation path, wherein receiving the first reference signal via the first propagation path involves receiving a component of the reference signal via the first CED, measuring a first reception property of the first reference signal, and providing, to the first CED, a message for configuring the first CED to induce a first phase shift in the first propagation path. Further examples provide a further method of operating a first CN methods of operating a CED as well as respective first CNs, second CNs and CEDs.
