本发明涉及通信技术领域，尤其涉及一种TDD/FDD可配置装置、方法、射频模块及通信设备。The present invention relates to the field of communication technologies, and in particular, to a TDD/FDD configurable apparatus, method, radio frequency module and communication equipment.
背景技术Background technique
随着无线网络的发展和不同地区国家无线频谱的陆续放发，越来越多的运营商同时拥有时分双工(Time Division Duplexing，TDD)和频分双工(Frequency DivisionDuplexing，FDD)的频谱。例如，一部分运营商拥有FDD 1.8GHz和TDD F频段的频谱，一部分运营商拥有FDD1.8GHz频段和TDD1.9GHz频段的频谱，或者拥有2.6GHz频段的TDD和FDD频谱等。With the development of wireless networks and the successive release of wireless spectrums in different regions and countries, more and more operators have both time division duplex (Time Division Duplexing, TDD) and frequency division duplex (Frequency Division Duplexing, FDD) spectrums. For example, some operators own the spectrum of FDD 1.8GHz and TDD F-band, some operators own spectrum of FDD1.8GHz and TDD1.9GHz, or have TDD and FDD spectrum of 2.6GHz, etc.
目前，在FDD和TDD的网络站点建设中，FDD和TDD各自设置独立的射频模块，且需要针对FDD和TDD设置两张天面，其中，FDD天面用于安装支持FDD频段射频信号收发的FDD天线，TDD天面用于安装支持TDD频段射频信号收发的TDD天线。针对已建设好的FDD或TDD网络站点，若要增加另一种制式的网络支持，例如，在已建设好的FDD网络站点新增TDD制式的网络支持，则需要单独增加TDD射频模块和TDD天面，或者将FDD射频模块和TDD射频模块通过合路器合路后共用天线一张天面来实现。At present, in the construction of FDD and TDD network sites, FDD and TDD are each set up with independent radio frequency modules, and two antennas need to be set up for FDD and TDD. Among them, the FDD antenna is used to install the FDD that supports the transmission and reception of radio frequency signals in the FDD frequency band. Antenna, the TDD antenna is used to install the TDD antenna that supports the transmission and reception of radio frequency signals in the TDD frequency band. For an established FDD or TDD network site, if you want to add another standard network support, for example, to add TDD standard network support to an already built FDD network site, you need to add TDD radio modules and TDD antennas separately. face, or the FDD radio frequency module and the TDD radio frequency module are combined by a combiner and then share the same antenna.
然而，在部分场景下，新增天面的设置可能会受到空间的限制，从而增加网络站点的建设难度，并导致网络站点的运营、维护成本增加。此外，采用合路器的方案虽然可以实现天面的共用，但合路器的使用会带来额外的功率损耗，降低站点覆盖距离。同时，合路器作为一个单独模块，会增加站点总的模块数量，为了降低损耗，一般合路器的体积、重量都较大，且合路器互调性能要求高、设计难度大，同样会增加站点的安装和建设难度。However, in some scenarios, the setting of the newly added sky surface may be limited by space, which increases the difficulty of building a network site and increases the operation and maintenance costs of the network site. In addition, although the scheme using the combiner can realize the sharing of the antenna, the use of the combiner will bring additional power loss and reduce the site coverage distance. At the same time, as a single module, the combiner will increase the total number of modules in the site. In order to reduce the loss, the volume and weight of the combiner are generally large, and the intermodulation performance requirements of the combiner are high and the design is difficult. Increase the difficulty of site installation and construction.
