Measurement procedure under adaptive frequency separation

A method in a network node of a wireless communication network, the method comprising:

• determining a wireless device is capable of narrow bandwidth operation, narrow bandwidth operation comprising transmitting and receiving wireless signals using a number of physical resource channels that is less than a total number of physical resource channels supported by the wireless communication network and using a transmit-receive frequency separation that is less than a transmit-receive frequency separation of a total bandwidth of the wireless communication network;
• determining a measurement pattern, the measurement pattern comprising:
• a first time period and a second time period;
• one or more radio measurements of a first type to be performed during the first time period on one or more radio signals transmitted in a first set of physical resource channels;
• one or more radio measurements of a second type to be performed during the second time period on one or more radio signals transmitted in a second set of physical resource channels, at least one physical resource channel of the second set of physical resource channels different than the physical resource channels of the first set of physical resource channels;
• and
• communicating the measurement pattern to the wireless device.
