Methods and Nodes for Setting Values of System Parameters Used in a Wireless Communication System

A user equipment, configured to apply a value of a system parameter used for performing random access in a cell within a wireless communication system, the user equipment comprising:

• a receiver circuit;
• a transmitter circuit;
• a processing circuit operatively coupled to the receiver circuit and the transmitter circuit;
• and
• a memory operatively coupled to the processing circuit;
• wherein the processing circuit is configured to:
• receive multiple different values of the system parameter from a network node of the wireless communication system, via the receiver circuit, each value being associated with a distinct tag,
• store, in the memory, the received multiple different values and the associated tags in a table allowing the tags as input for retrieving the values from the table;
• receive from the network node serving the cell, via the receiver, an indication of a value of the system parameter to apply for performing random access in the cell, the indication comprising a tag associated with the value;
• apply the value retrieved from the table using the tag of the indication;
• and
• perform random access in the cell using the applied value, using the transmitter circuit.

A network node configured for a wireless communication system, and for indicating a value of a system parameter used for performing random access in a cell served by the network node, the network node comprising:

• a transmitter circuit;
• and
• a processing circuit operatively coupled to the transmitter circuit and configured to use the transmitter circuit to:
• transmit multiple different values of the system parameter to a user equipment in the cell, each value being associated with a distinct tag;
• and
• transmit an indication of a value of the system parameter to apply for performing random access in the cell, the indication comprising a tag associated with the value.
