Claim One:
1. An apparatus for clustering small cells in Time Division Duplex (TDD) networks, comprising: circuitry configured to: determine a difference between (i) a first distribution ratio of an uplink traffic to a downlink traffic of a first small cell of the small cells and (ii) a second distribution ratio of an uplink traffic to a downlink traffic to a second small cell of the small cells; acquire a transmitting feature among the small cells in the TDD networks and uplink traffic and/or downlink traffic of each small cell, the transmitting feature including at least the difference between (i) the first distribution ratio and (ii) the second distribution ratio; calculate a possibility of clustering the first and second small cells together based on the transmitting feature; and cluster the first and second small cells together when the possibility is higher than a clustering threshold.
