Claim 16:
17. A non-transitory computer-readable medium comprising computer-executable instructions that, when executed by a processor, cause the processor to perform the following operations:
determining a load balancing condition, including at least one beam of beams providing beamformed radio access as a candidate beam and at least one target radio access entity for offloading terminal entities being currently served by the candidate beam,
specifying a load balancing hypothesis for a hypothetical case of deactivation of the candidate beam, including information on an impact of the hypothetical beam deactivation with respect to the terminal entities being currently served by the candidate beam by offloading to the at least one target radio access entity, wherein the specifying comprises:
retrieving, for the terminal entities being currently served by the candidate beam, results of radio resource management measurements with respect to the at least one beam of beams providing beamformed radio access in a cell of the at least one target radio access entity and radio access in at least one cell of the at least one target radio access entity, and
evaluating whether or not a coverage hole for one or more of the terminal entities being currently served by the candidate beam is caused when deactivating the candidate beam based on the retrieved radio resource management measurements results,
wherein the load balancing hypothesis is specified when it is evaluated that a coverage hole is not caused for any one of the terminal entities being currently served by the candidate beam when deactivating the candidate beam;

inquiring non-acceptance of deactivation of the candidate beam from the at least one target radio access entity on the basis of the load balancing hypothesis, and
deactivating the candidate beam when acceptance of deactivation of the candidate beam is inquired from the at least one target radio access entity.
