A method for determining a layout of a wireless communication network is provided in the present invention. Numerous realizations of user device placement in a considered geometry are measured to reflect the practical distribution of the user devices in a more accurate way than the conventional approach which emulates the randomness of placements of user devices using a tractable stochastic process. Moreover, a scenario sampling approach is used to provide a lower-complexity and higher efficient way to yield optimal base station deployment results while guaranteeing the quality of service of a specified majority of the overall user device realizations.

An objective is to enable communications properly using an Scell even in a case where a radio base station which transmits “Activate command” and a radio base station which manages an Scell are different when “Inter-site CA” is performed. A radio base station eNB #1 according to the invention includes a transmission unit 12 configured to transmit an “Activate command” which is a command to activate a cell #B to a mobile station UE and thereafter notify a radio base station eNB #10 that the cell #B is activated.

Provided is a control device that controls flight vehicles having an antenna for forming a cell on the ground to provide a wireless communication service to a user terminal in the cell. The control device includes a replacement control unit that controls replacement of a first flight vehicle covering an object area on the ground by means of a cell with a second flight vehicle. The replacement control unit controls the first flight vehicle and the second flight vehicle such that the second flight vehicle moves to a location corresponding to the location of the first flight vehicle, the second flight vehicle and the first flight vehicle start providing a wireless communication service to a user terminal by Coordinated Multiple Point transmission/reception (CoMP), and then the first flight vehicle stops forming its cell.

A radio terminal accommodation determination device includes: an average received power calculation unit for calculating an average received power for each mesh constituting an area; an interfering signal power CDF creation unit for creating a cumulative distribution function of all interfering signal powers; an intended signal power PDF creation unit for creating a fourth probability density function indicating a probability density function of an intended signal power; and a communication success rate estimation unit for calculating, for each base station, a communication success rate of the intended terminal based on the cumulative distribution function and the fourth probability density function.

Location-aware spatial reuse may be provided. First, an Overlapping Basic Service Set (OBSS) transmission to be received at a device may be detected by a first Access Point (AP). Then the location of the device may be determined. Next, based on the determined location, it may be determined that the device is out of range of the first AP. Then, in response to determining that the device is out of range of the first AP, the first AP may perform an OBSS Packet Detect (PD) based Spatial Reuse (SR) transmission without reducing a transmit (Tx) power for the transmission.
