Claim 10:
11. A method, performed by a user equipment (UE) for configuring access to a cell in a time-division-duplexed (TDD) radio access network (RAN) via a physical random-access channel (PRACH), the method comprising:
receiving, from a network node serving the cell, first information indicating that a first PRACH configuration should be used for accessing the cell via the PRACH, wherein:
the first PRACH configuration is one of a first subset of available PRACH configurations,
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,
the second subset is robust against remote interference from a distance less than a second threshold,
the first subset is robust against remote interference from a distance less than a first threshold, and
the first threshold is greater than the second threshold; and

subsequently receiving, from the network node, second information indicating that a second PRACH configuration should subsequently be used for accessing the cell via the PRACH, wherein the second PRACH configuration is one of the second subset.
