Method and apparatus for adjusting air interface capacity density

Disclosed are a method and apparatus for adjusting air interface capacity density. The method comprises: determining whether a target physical cell requiring air interface capacity density adjustment exists in a logical cell, wherein the logical cell comprises one or more physical cells, each physical cell comprises a set of pico radio remote units (pRRUs), and one physical cell corresponds to one baseband branch; and when the determining result is yes, adjusting air interface capacity density of the target physical cell. Thus, by implementing embodiments of the present invention, air interface capacity density of a physical cell can be dynamically adjusted according to the actual situation of the physical cell in a logical cell, thereby improving the utilization rate of air interface capacity in the logical cell; further, splitting or combining of the logical cell is not needed, and it is unnecessary to allocate new cell license resources to the logical cell, thereby reducing waste of cell license resources;
