The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.

A new access networking framework is provided for supporting small cell deployments based on the sharing of network resources. A smart gateway framework flexibly accommodates eNB connections and dynamically assigns uplink transmission resources to the eNBs. Novel techniques are also introduced for sharing the small cell infrastructures among multiple operators through virtualization and SDN based reconfiguration.

Transfer learning based on prediction determines a similarity between a source base station and a target base station. Importance of parameters is determined and training is adjusted to respect the importance of parameters. A lack of historical data is compensated by selecting a base station as source base station which has a larger amount of historical data.

A communication controller includes a memory, and processor circuitly coupled to the memory and configured to calculate an expected value of an interference amount in a first wireless communication apparatus and a second wireless communication apparatus on the basis of a first use probability in a first frequency bandwidth, a second use probability in a second frequency bandwidth, the first and second frequency bandwidth being calculated on the basis of the traffic of a terminal apparatus, and received power of a signal received by the first wireless communication apparatus from the second wireless communication apparatus, assign a first or second channel to the first and second wireless communication apparatuses on the basis of the expected value, and notify the first or second channel which has been assigned to the first and second wireless communication apparatuses.

The present invention relates to a method for requesting the selection of a master management apparatus through a server by a management apparatus enabling television white space (TVWS) apparatuses to coexist in a TVWS. The method includes the steps of: determining whether the trigger condition of the process for selecting the master management apparatus is satisfied; and requesting the selection of the master management apparatus by the server, wherein the master management apparatus is configured to determine a channel selection in the TVWS for terminals connected to the master management apparatus and a slave management apparatus, and the trigger condition can be based on the load balance parameters or geographical coverage parameters of the management apparatus.

Systems and methods for automatically configuring a distributed antenna system are provided. A configuration sub-system of the distributed antenna system can identify signal parameters for downlink signals received from one or more base stations via inputs of a unit in the distributed antenna system. The configuration sub-system can automatically determine a configuration plan for the distributed antenna system based on the automatically identified signal parameters. The configuration plan specifies how to combine subsets of the downlink signals for routing to remote antenna units of the distributed antenna system.
