摘要： The present invention discloses an adaptive parameter adjustment method for a hybrid precoding millimeter-wave transmission system. The method includes the following step: interacting between a transmitter and a receiver for a number of radio frequency chains that need to be established. The receiver calculates, according to a received signal power at the time of established a different number of radio frequency chains and a total power consumption at the time of established the different number of radio frequency chains, the number of the radio frequency chains that need to be established. According to the present invention, under a condition of balancing power consumption and a rate, a number of radio frequency chains that need to be established is adaptively selected, so as to optimally configure power consumption and a transmission rate in a millimeter-wave transmission system.

摘要： The present invention discloses a method for fusing baseband resources between networks of different standards. The method includes the following steps: performing coding on baseband data by using a coding scheme of a first network, and then performing modulation by using a modulation scheme of a second network. The present invention further discloses a corresponding base station and a terminal. In the present invention, in a case of collocation/co-device or a co-baseband resource pool, a correspondence between channel coding/de-coding and modulation/demodulation in each network is changed to enable the network to implement dynamic matching according to a specific factor such as a network status service type, thereby improving system performance of the network and significantly improving transmission performance.

摘要： An uplink pilot sequence allocation method in a massive MIMO system is disclosed, the system including the master base station in the master cell and a neighboring base station in a neighboring cell, including: the neighboring base station comparing a primary eigen-space between a user group of the neighboring cell and the neighboring base station, with an interference eigen-space between a user group of the master cell close to the neighboring base station and the neighboring base station, and determining whether the user group of the neighboring cell can reuse uplink pilot sequence resources used by the user group of the master cell. In a manner of increasing information exchange, intercell cooperative uplink pilot sequence allocation is achieved, and uplink pilot contamination in a multi-cell massive MIMO system is reduced effectively.

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 NCP, 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.

摘要： The present invention discloses an uplink resource sharing method, base station and terminal, wherein, the uplink resource sharing method comprises: performing the LBT on a granted subframe, allocated to a terminal by a base station, by the terminal; transmitting data if the LBT is finished on the granted subframe; and performing the LBT on another subframe if the LBT is not finished on the granted subframe. The present invention solves the problem of resource waste caused by the fact that the terminal cannot finish LBT in a frame allocated to the frame by a base station, and reduces a probability of increase of an uplink grant number caused by failing of uplink scheduling.
