Method and apparatus for adjusting air interface capacity density

Embodiments of the present invention disclose a method and an apparatus for adjusting air interface capacity density, where the method includes: determining whether a target physical cell whose air interface capacity density needs to be adjusted exists in a logical cell, where the logical cell includes one or more physical cells, each physical cell includes a group of pico radio remote units pRRUs, and one physical cell corresponds to one baseband tributary; and when a determining result is that a target physical cell whose air interface capacity density needs to be adjusted exists in the logical cell, adjusting the air interface capacity density of the target physical cell. Therefore, by implementing the embodiments of the present invention, air interface capacity density of a physical cell in a logical cell can be dynamically adjusted according to an actual situation of the physical cell.
