Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first," "second," and the like in the description and claims of the present invention and in the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Generally, the method shown in fig. 1 is mainly adopted for the classical radio frequency path of the mobile terminal, that is, a duplexer method is adopted for both the receiving RX and the transmitting TX of each system (there is also a part of the frequency band shared RX between 2G/3G/4G), and the rest is strictly distinguished. The antenna switch in fig. 2, whose path is open only when the corresponding frequency band is used for communication, and the other paths are closed, is generally called a single-pole four-throw switch (SP 4T). For example, when we realize GSM850 communication, the rest of the path is disconnected from the switch. That is to say, if the dual-card dual-pass needs to be supported on hardware, two sets of such device channels are needed to operate, and the hardware cost is extremely high.
