Abstract
A method of scheduling wireless data transmissions between a mobile terminal (701) and a base station using multiple component carrier signals is disclosed. The method comprises the steps of: receiving in the mobile terminal information from the base station indicating available component carriers; detecting in the mobile terminal at least one dynamic parameter indicative of the mobile terminal's current ability to handle component carriers having non-contiguous bandwidths; determining in the mobile terminal in dependence of the at least one dynamic parameter which of the available component carriers to utilize; and transmitting from the mobile terminal to the base station information indicating the component carriers determined to utilize. By doing this the mobile terminal may choose to limit the number of component carriers used in situations where it is disadvantageous, such as situations where the power consumption of supporting multiple component carriers is high or situations where complex hardware is needed.
