Selection of transmitters in an indoor radio system

A network node the network node comprising:

• processing circuitry
• memory coupled with the processing circuitry, wherein the memory includes instructions that when executed by the processing circuitry causes the network node to perform operations comprising:
• receive an output from a digital twin of the indoor radio system, the output comprising a plurality of indicators of a radio propagation property of a signal between a receiver and a respective transmitter from a plurality of transmitters in the indoor radio system;
• filter at least some of the plurality of transmitters into a plurality of subsets of transmitters that are active for the receiver based on the outputted plurality of indicators;
• generate a first message comprising an identifier per transmitter in the plurality of subsets of transmitters for the receiver;
• and
• transmit the first message towards a device for selection of a transmitter per subset of transmitters for the receiver.
