Abstract
Embodiments of the disclosure provide methods and apparatuses for cancelling cross-subframe co-channel interference (CCI), the method comprising receiving a channel quality indicator (CQI) of a cross-subframe from a user equipment (UE), the cross-subframe is a downlink subframe that is interfered by an uplink subframe in a neighboring cell; determining if the UE should be scheduled during cross-subframes by comparing the CQI with an adaptive threshold; and scheduling the UE during the cross-subframes if the UE is determined to be scheduled. By means of determining the resources scheduling based on an adaptive threshold, CCI may be cancelled and the overall resource usage will be increased according to the present invention. Furthermore, the adaptive threshold scheme can be easily implemented in practice.
