摘要： An electronic apparatus and a method for a spectrum management device are provided. The electronic apparatus includes processing circuitry configured to: acquire, for a predetermined primary system, an interference radiation map representing interference amounts of secondary systems at locations in a management region of the spectrum management device to the primary system; and determine an exclusion zone for the primary system based on the interference radiation map, where secondary systems in the exclusion zone cannot use a spectrum which is being used by the primary system.

摘要： A wireless communication method and a wireless communication device are provided. Specifically, a spectrum management device is provided, which comprises one or more processors configured to estimate a future moving trajectory of a communication device based on a location of the communication device and an environment where the communication device is located, where the communication device is an unpredictable mobile device; determine a trajectory radiation area to be interfered by the communication device as it moves along the future moving trajectory; and instruct the communication device or an interfered device in the trajectory radiation area which is subjected to co-frequency interference with the communication device to perform an operation for reducing interference.

摘要： An interference suppressing method and device in a dynamic frequency spectrum access (DSA) system. The system includes: a frequency spectrum management device, a primary system including a plurality of primary devices, and a secondary system including a plurality of secondary devices. The method includes: transmitting position information of each of the secondary devices to the frequency spectrum management device; determining, by the frequency spectrum management device, a weight factor for a specific secondary device according to the received position formation; and performing a second-stage precoding, and in the second-stage precoding, adjusting, by using the weight factor, an estimated power of the specific secondary device leaking to the other secondary device.
