Duty cycle aware scheduling for wireless networks

New signaling is defined from wireless devices (10) to a wireless communication network, concerning the wireless devices' duty cycle statuses. This allows the network to optimize its control of the radio resource usage. Additionally, embodiments described herein provide new signalling from the network to wireless devices concerning the network's duty cycle status. This allows wireless devices (10) to optimize their idle mode operation, including decisions whether to request a connection setup or remain in idle mode. Embodiments described and claimed herein provide a set of simple methods for operating a cellular system in a duty cycle controlled radio frequency band.
