Use of system response time for cell or beam (re)selection

A User Equipment, UE, for cell or beam selection or reselection for a cellular communications system, the UE comprising:

• one or more receivers;
• and
• processing circuitry associated with the one or more receivers, the processing circuitry configured to cause the UE to:
• receive response times from one or more Radio Access Network, RAN, nodes via one or more broadcast messages;
• and
• perform a cell or beam selection or reselection procedure that takes into consideration the response times received from the one or more RAN nodes;
• wherein the response times take into account delays and loads on interfaces northbound, in terms of network topology, from the one or more RAN nodes.

A Radio Access Network, RAN, node for a cellular communications system, the RAN node comprising:

• a network interface;
• and
• processing circuitry associated with the network interface, the processing circuitry configured to cause the RAN node to:
• transmit one or more response times associated with the RAN node, one or more cells served by the RAN node, or one or more beams served by the RAN node via one or more broadcast messages;
• wherein the response times take into account delays and loads on interfaces northbound, in terms of network topology, from the RAN node.
