摘要： A first base station and mobile station are capable of mitigating interference resulting from communications from a second base station. The base station can determine if at least a portion of a paging slot overlaps with an available interval (AI) of the second base station in which the second base station transmits. The first base station adjusts an occurrence of the paging slot such that the paging slot overlaps and/or occurs within an unavailable interval (UAI) of the second base station wherein the base station does not transmit or transmits with limited resources.The mobile station also can determine if at least a portion of a listening slot overlaps with the AI and, using the same procedure that the first base station uses to recalculate the paging slot, recalculates the listening slot such that the listening slot overlaps and/or occurs within the UAI of the LDC mode.
