Claim 16:
17. A wireless device comprising:
one or more transmitters;
one or more receivers; and
processing circuitry associated with the one or more transmitters and the one or more receivers, the processing circuitry configured to cause the wireless device to:
detect a Synchronization Signal Block, SSB; and
transmit 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.
