摘要： The present invention discloses a network optimization method for a large-scale MIMO network and a base station thereof. The base station enables, according to a user minimum SINR threshold of each user in a preset cell, instantaneous spectral efficiency of the cell at a specific moment to approximate or reach a maximum value. In the present invention, a newly added user minimum SINR threshold parameter is configured, and a characteristic of a concave function is used, so that average spectral efficiency and edge spectral efficiency of each cell are simply and effectively controlled, so as to achieve an objective of coordination adjustment of network capacity and network coverage.

摘要： The present invention discloses a calibration method for parallel multi-channel wireless channel measurement and a calibration system thereof. The transmitting end and the receiving end are disconnected, and are respectively connected to the calibration receiving channel and the calibration transmitting channel, and the calibration receiving channel/calibration transmitting channel cooperates with a measurement channel in air interface measurement, to calibrate a channel response characteristic of the transmitting end and the receiving end. By means of the present invention, a current channel response characteristic between multiple channels can be online supervised in real time, so as to ensure that a measurement error because of an impact of mutual interference between multiple channels can be avoided in the channel measurement process.

摘要： The present invention discloses a cell clustering method, used to classify multiple small cells into N clusters and including the following steps: based on throughputs, respectively placing N small cells having a largest interference with each other into the N clusters to initialize the clusters; and based on the throughputs, separately adding a small cell having a smallest interference with the clusters into the clusters, and repeating the step until all the small cells are allocated into the clusters. The present invention further discloses a spectrum overlapping multiplexing method based on the cell clustering method. According to the present invention, the cell system average spectral efficiency and the cell edge spectral efficiency in an ultra dense network can be improved.

摘要： The present invention discloses a fog computing-oriented method for describing a node computing capability and a fog computing-oriented method for exchanging a node computing capability, and further discloses a fog computing-oriented node device. In the present invention, key parameters affecting a computing capability are further explored, and therefore, a computing capability of a node can be described more accurately. After these key parameters are obtained, a computing type and a scale of data that are suitable for being processed by the node can be better determined, and a delay and costs that are needed by the node to execute a computing task can be better preestimated, so as to further assist in computing task allocation between nodes.

摘要： The present invention discloses a detection method, a synchronization method, and a terminal for a symmetrical synchronization signal. The detection method includes the following steps: obtaining a received signal of a synchronization signal for synchronous detection, and subsequently, performing an auto-correlation calculation on the received signal twice in the time domain, where the received signal includes a first-part received signal whose length is N and a second-part received signal whose length is N CP , the first-part received signal is symmetrical about a first central point, and the second-part received signal is symmetrical about a second central point. With low complexity of calculation and good detection performance, and being insensitive to a carrier frequency offset (CFO), the present invention is particularly applicable to an Internet of Things (IoT) environment.
