摘要： There is provided a communication control device including a power distribution unit configured to distribute, to one or more secondary systems, a transmission power accepted for a secondary usage of a frequency channel which is protected for a primary system, and a notification unit configured to notify each secondary system of a value of a second transmission power which is decided depending on a value of a first transmission power distributed by the power distribution unit. Upon updating the transmission power, only in a case where a value of the second transmission power which is previously notified and a value of the first transmission power which is newly distributed by the power distribution unit satisfy a predetermined condition with respect to a certain secondary system, the notification unit notifies the secondary system of a new value of the second transmission power.

摘要： Even when the lengths of data items to be transmitted to users are not the same, the frames multiplexed at the same time finally have the same frame length and are transmitted.Even when the lengths of frames for the users are not the same at the time when a transmission request is received from a higher layer, a communication apparatus reconfigures at least two of the frames having short lengths into a frame having a long length through Aggregation so that the frames finally have the same frame length and transmits the frames at the same time in a multiplexed manner. On the transmitter side, the transmission power used per destination communication station can be increased due to a decrease in the total number of multiplexed frames. On the receiver side, an unstable AGC operation can be prevented.

摘要翻译： 即使当发送给用户的数据项的长度不相同时，同时多路复用的帧最终具有相同的帧长并被发送。 即使在从较高层接收到发送请求时用户的帧的长度不相同的情况下，通信装置通过聚合将具有短长度的至少两个具有短长度的帧重新配置为长度长的帧，所以 帧最终具有相同的帧长度并且以多路复用的方式同时发送帧。 在发射机侧，由于多路复用帧总数的减少，每个目的地通信站所使用的传输功率可能会增加。 在接收机侧，可以防止AGC动作不稳定。

摘要： Signal decoding apparatus, signal decoding method, program, and information record medium are provided and can accomplish not only high-speed and high-capacity communication, but high-accuracy decoding. An initial channel estimation section 31 estimates an initial channel with a pilot symbol added at the beginning of each packet. After a replica of a transmission symbol is generated, for a reception signal vector, CCI components for L transmission antennas are generated. A CCI canceller 33 removes the CCI components from the reception signal vector. After the reception symbol vector from which the CCI components had been removed has been obtained, a division device 34 obtains an instantaneous estimation value. An update condition determination section 35 detects deterioration of a channel response accuracy based on a threshold value. An instantaneous estimation value whose SNR has been determined to be insufficient is discarded. An averaging circuit 36 outputs a channel response estimation matrix at time t+1 obtained by an averaging process and supplies the matrix to a symbol decoding section 13.
