1. A method in a wireless communication terminal, the method comprising:

  • receiving, at the terminal, an aggregated carrier including a first component carrier and a second component carrier belonging to a same base station;

    determining a signal characteristic of the first component carrier and a signal characteristic of the second component carrier;

    determining a level of interference from a signal received on the first component carrier to a signal on the second component carrier, belonging to the same base station, based on one of a ratio and comparison of a difference of a logarithm of the signal characteristic of the first component carrier with respect to the signal characteristic of the second component carrier; and

    providing signal interference information to a serving base station when the determined interference level satisfies a condition.
