Abstract
A method of communicating in a wireless telecommunication network includes establishing a control channel at a control channel frequency in a first frequency band between a wireless terminal and a base station gathering information about a second frequency band indicative of at least a first portion of the second frequency band not being allocated to at least one other device and/or service; determining if the traffic load in the first frequency band is above a traffic load threshold; transmitting control channel data from the base station to the wireless terminal if the traffic load in the first frequency band is above the traffic load threshold; and establishing a communication channel at the communication channel frequency between the wireless terminal and the base station if the traffic load in the first frequency band is above the traffic load threshold. A base station associated with the method is also provided.
