Embodiment 1: the embodiment of the invention 1 provides a kind of implementation method of many aerial intermediate radio frequency module, is illustrated in figure 2 as the schematic flow sheet of 1 supplying method of the present embodiment, and described method comprises:
Step 21: the middle radio-frequency module of a plurality of receptions and a plurality of emissions is split according to demand.
In this step, the middle radio-frequency module of a plurality of receptions and a plurality of emissions can be set n for and receive and n the middle radio-frequency module of launching, and wherein n is integer; According to the user demand of reality, this n reception and n the middle radio-frequency module of launching can be split into m and receive and m the middle radio-frequency module of launching, wherein m also is integer, and n is the integral multiple of m.
For instance, be illustrated in figure 3 as the schematic diagram that radio-frequency module RE among the 2nT2nR is split into radio-frequency module among two nTnR, among the figure: according to actual user demand, radio-frequency module can be used as an integral body and uses among the 2nT2nR, can be divided into also that radio-frequency module uses respectively among two nTnR, specifically can decide according to the user demand of reality.Radio-frequency module among 4T4R for example, can use as a middle radio-frequency module according to demand, also can be split into radio-frequency module among two 2T2R, or be split into that radio-frequency module comes independent design among four 1T1R, specifically can decide according to network condition and the user demand of reality, if in the radio-frequency module, also requirement can be used according to radio-frequency module among two 2T2R, just can design by radio-frequency module among two 2T2R so here in design 4T4R.
In the specific implementation process, above-mentioned fractionation work can be according to actual user demand by manually arranging; Also can in webmaster, preset splitting condition and strategy, be configured by webmaster.
Specifically in implementation procedure, each part in the middle radio-frequency module can be designed respectively, with the filter in the middle radio-frequency module and power amplifier part, specifically this filter can be split into n/m independently filter module according to user demand; The power amplifier part also splits into n/m independently power amplifier module according to user demand simultaneously, and its quantity is corresponding with the quantity of the described filter module that splits into; And the radio frequency part in the middle radio-frequency module generally can adopt independently radio-frequency channel, and switches between each radio-frequency channel by radio-frequency (RF) switch.
In addition, independently reception can be set in the middle radio-frequency module of the m that splits into reception and m emission and launch local oscillator, when support different frequent points or frequency range, can be configured each radio-frequency channel separately like this.
For instance, be illustrated in figure 4 as the specific implementation structural representation that radio-frequency module among the 2nT2nR is split into radio-frequency module among two nTnR, among the figure: the filter of radio-frequency module or duplexer among the 2nT2nR (are filter in TDD system; Be duplexer in FDD system), the separate filter module that can split into nTnR designs, and has been designed in the drawings two independently filter modules, and when supporting different frequency range, each radio-frequency channel is configurable corresponding filter all; Accordingly, the power amplifier of radio-frequency module part also can split into the independent power amplifier module of nTnR among the 2nT2nR, and when supporting the different frequency range configuration, each radio-frequency channel can configure corresponding power amplifier part.
