1. A network node configured to communicate with a wireless device, WD, the network node comprising:
a transceiver configured to:
transmit an indication of a number of zero or more repetitions of a message related to random access, RA, to be transmitted by the WD in response to a random access response, RAR, message transmitted to the WD;
receive at least one message related to RA and zero or more repetitions of the message related to RA; and
transmit a frequency hop, FH, field to indicate whether the message related to RA is transmitted using one of inter-slot frequency hopping and intra-slot frequency hopping, the FH field being interpreted based at least in part on an aggregation factor that indicates the number of zero or more repetitions of the message related to RA,
the FH field interpretation is implemented so that:
when the aggregation factor=1, (no repetition) FH=1 means intra-slot;
when the aggregation factor >1, FH=1 means inter-slot; and
FH=0 means no frequency hopping irrespective of the aggregation factor.
