A method of reducing inter cell interference in a wireless communication network, a network control node, network access node, user equipment and computer program product operable to implement that method. The method is for use in a network comprising a plurality of network access nodes, each supporting a region of radio overage, and the method comprises: discovering, for a first network access node, at least one adjacent network access node; allocating at least one predetermined shared radio channel for radio communication commenced within an overlapping radio coverage region between said first network access node and said adjacent network access node; and communicating an indication of said at least one predetermined shared radio channel to said first network access node and said adjacent network access node. The method enables shared radio channels to be used in a “soft handover” type scenario, by enabling adjacent network access nodes to decipher and decode transmissions made by user equipment operating in overlap regions in a network. Such methods may be particularly suited to user equipment operating in a Cell_FACH mode.

The invention is directed to systems, methods and computer program products for standardized inter-base station reporting of pilot contamination for improved pilot resource re-use. Specifically, possible pilot channel contamination is detected at first user equipment and, in response to the detection, a request is transmitted for the first user equipment to forego transmission during a next frame designated for transmitting a pilot signal. A determination is made within the next frame if other second user equipment, which are communicating with a neighboring base station, are transmitting on a same channel as a pilot channel of the first user equipment and, in response to such a determination, a report is sent to the neighboring base stations that indicates that the pilot channel on which the first user equipment is communicating is currently contaminated.

[Object] To be able to detect a terminal in the vicinity of a small cell base station and appropriately provide an opportunity for handover even when the small cell base station is put into a standby state. [Solution] Provided is a radio communication apparatus including: a radio communication unit configured to provide radio communication service to one or more terminals within a second cell which overlaps with a first cell; a detecting unit configured to detect a terminal existing in the vicinity by monitoring strength of an uplink signal transmitted in the first cell while an operation mode of the radio communication unit is set at a standby mode; and a mode setting unit configured to switch the operation mode of the radio communication unit to an active mode when the detecting unit detects the terminal existing in the vicinity.

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 base station, includes: a transmitter, configured to transmit a first coexistent interference frequency set configured for UE to a target base station, when the UE is handed over from a source base station to the target base station; wherein coexistence interference on each frequency in the first coexistence interference frequency set is to be evaluated by the UE when the UE is in a cell of the source base station, and the evaluation results indicate that whether there exists coexistent interference on each frequency in the first coexistent interference frequency set.

A method includes determining if a user equipment is to be handed over to a target radio access node and if said user equipment suffers co-existence interference, and providing a message to be sent to said target radio access node, said message including interference information indicating that said user equipment suffers co-existence interference.
