1. A base station comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the base station to:
transmit a first message comprising a subframe allocation bitmap indicating a plurality of Almost Blank Subframes, wherein the plurality of Almost Blank Subframes consists of second, fourth, seventh, and ninth subframes of each frame in a plurality of frames;
transmit, to a wireless device, a first measurement subframe allocation bitmap indicating a first plurality of measurement subframes, of a primary carrier, that are not the plurality of Almost Blank Subframes;
transmit, to the wireless device, a second measurement subframe allocation bitmap indicating a second plurality of measurement subframes, of the primary carrier, different from the first plurality of measurement subframes; and
transmit a first Almost Blank Subframe at a power level that is lower than during a subframe that is not an Almost Blank Subframe.
