Classification: CPC H | IPC H

Claim 0:
1. An apparatus comprising:
one or more processors configured to cause a radio access node to:
determine a first reference timing of a first communication connection between the radio access node and a second, parent radio access node; and
determine a second reference timing of a second communication connection between the radio access node and a third, child radio access node;
generate a request for the child radio access node to perform a timing advance adjustment based on the first and second reference timings, so that an uplink receive signal transmitted by the child radio access node arrives at a same time at the radio access node as a downlink receive signal transmitted by the parent radio access node arrives at the radio access node in case of frequency division multiplexed signals; and
apply different analog spatial beamformers for the receive signals transmitted by the parent radio access node and the child radio access node.
