POSITIONING REFERENCE SIGNAL BASED POSITIONING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18282533 titled 'POSITIONING REFERENCE SIGNAL BASED POSITIONING
Simplified Explanation
The abstract describes a method of operating a terminal node configured to communicate with network nodes using a re-configurable relaying device (RRD) that provides spatial filters for incident signals. The method involves receiving positioning reference signals (PRSs) from network nodes, and when PRSs from the same network node are received, transmitting a measurement report message with positioning information for the terminal node based on the received PRSs.

Original Abstract Submitted
A method of operating a terminal node () configured to communicate with one or more network nodes using a re-configurable relaying device (), RRD, is provided. The RRD is re-configurable to provide spatial filters, each one of the spatial filters being associated with a respective spatial direction into which incident signals are selectively transmitted by the RRD. The method comprises receiving () a plurality of positioning reference signals, PRSs, transmitted by the one or more network nodes, and, upon a first PRS () and a second PRS () of the plurality of PRSs being received from a same network node () of the one or more network nodes, the first PRS () being received along a path which is relayed at the RRD (): transmitting () a measurement report message comprising positioning information for the terminal node () based on at least the first PRS () and second PRS ().
