1. A method in a network node, the method comprising:
monitoring unlicensed spectrum access attempts for transmissions to and/or from a first User Equipment (UE) in a first group of UEs configured to use unlicensed spectrum to send uplink transmissions and/or receive downlink transmissions, wherein the monitoring comprises monitoring a total number of access attempts by the first UE within a predetermined period; and
in response to the total number of access attempts by the first UE within the predetermined period exceeding a first threshold, causing the UEs in the first group to use licensed spectrum to send uplink transmissions and/or receive downlink transmissions.
