Claim 10:
11. A method performed by a wireless device in a cellular communications network, the method comprising:
detecting a Synchronization Signal Block, SSB; and
transmitting a Physical Random Access Channel, PRACH, preamble on a PRACH occasion mapped to the detected SSB, where a mapping between an SSB index and transmit beam directions performed by a respective base station is defined taking remote interference into consideration such that one or more SSBs of the SSB index that correspond to PRACH occasions that are resistant to remote interference are mapped to one or more beam directions having a predefined level of remote interference, respectively, wherein the mapping results in a beam direction to SSB index mapping.
