Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A base station for a cellular communications network comprising processing circuitry configured to cause the base station to:
measure remote interference on a plurality of beam directions;
determine a mapping between the plurality of beam directions and Synchronization Signal Block, SSB, index, resulting in a beam direction SSB index mapping, taking into consideration remote interference, wherein determining the mapping between the SSBs and the plurality of beam directions comprises performing the mapping between the SSBs and the plurality of beam directions such that one or more of the SSBs that correspond to Physical Random Access Channel, PRACH, occasions that are resistant to remote interference are mapped to one or more beam directions having a predefined level of remote interference, respectively; and
use the beam direction to SSB index mapping.
