1. A method comprising:
- transmitting, by a base station, a first message comprising;
an initial subframe allocation repetition period;
an initial subframe allocation offset; and
an initial subframe allocation bitmap indicating an initial plurality of subframes, the initial plurality of subframes comprising an initial plurality of Almost Blank Subframes; and
transmitting, by the base station and after an increase in traffic load of the base station by an amount greater than a load value, a second message comprising;
the initial subframe allocation repetition period;
the initial subframe allocation offset; and
an updated subframe allocation bitmap different from the initial subframe allocation bitmap, the updated subframe allocation bitmap indicating a second plurality of subframes, the second plurality of subframes comprising an updated plurality of Almost Blank Subframes, the updated plurality of Almost Blank Subframes comprising a smaller number of Almost Blank Subframes than the initial plurality of Almost Blank Subframes.

Abstract
A base station transmits a message after an increase in the number of wireless devices and/or a traffic load by an amount greater than a value. The message comprises an updated subframe allocation bitmap indicating a second plurality of subframes including an updated plurality of almost blank subframes. The updated plurality of almost blank subframes includes a smaller number of almost blank subframes than an initial plurality of almost blank subframes.

12. A base station comprising:
-
one or more processors; and memory storing instructions that, when executed, cause the base station to; transmit a first message comprising; an initial subframe allocation repetition period; an initial subframe allocation offset; and an initial subframe allocation bitmap indicating an initial plurality of subframes, the initial plurality of subframes comprising an initial plurality of Almost Blank Subframes; and transmit, after an increase in traffic load of the base station by an amount greater than a load value, a second message comprising; the initial subframe allocation repetition period; the initial subframe allocation offset; and an updated subframe allocation bitmap different from the initial subframe allocation bitmap, the updated subframe allocation bitmap indicating a second plurality of subframes, the second plurality of subframes comprising an updated plurality of Almost Blank Subframes, the updated plurality of Almost Blank Subframes comprising a smaller number of Almost Blank Subframes than the initial plurality of Almost Blank Subframes. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
