Abstract
The present application discloses an apparatus and a method for clustering small cells in TDD networks and a base station including the apparatus. The apparatus includes: an information acquiring unit, configured to acquire a transmitting feature among the small cells in the TDD networks and uplink traffic and/or downlink traffic of each small cell; and a clustering unit, configured to clustering the small cells based on the transmitting feature among the small cells and the uplink traffic and/or downlink traffic of each small cell acquired by the information acquiring unit, to obtain at least one small cell cluster.
Claims17
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.
A method for clustering small cells in Time Division Duplex (TDD) networks, the method comprising:
