Claim 17:
18. A method, performed by a network node, for configuring a physical random-access channel (PRACH) of a cell in a time-division-duplexed (TDD) radio access network (RAN), the method comprising:
determining an increase in a level of remote interference in the cell;
in response to determining the increase, selecting a first PRACH configuration from a first subset of available PRACH configurations, wherein:
the first PRACH configuration is selected to avoid time-domain PRACH occasions during uplink (UL) symbols for which the remote interference is determined to be above a predetermined threshold,
the first subset of available PRACH configurations is more robust against remote interference than a second subset of the available PRACH configurations, and
the first subset is exclusive of the second subset; and

transmitting, to one or more user equipment (UEs), first information indicating that the first PRACH configuration should be used for accessing the cell via the PRACH.
