Based on the above-mentioned mobile terminal hardware structure and communication network system, various embodiments of the present application are presented.

First embodiment

It should be understood that, with the explosive growth of data services, in order to meet the user perceived demand when users use new services, mobile operators are actively deploying 4g+ networks (also called 4.5G networks) that use carrier aggregation (Carrier Aggregation, abbreviated as CA) technology, so as to provide users with as high a data transmission rate as possible by using spectrum resources in the hands as possible to the greatest extent, thereby ensuring better user experience. The CA technology combines a plurality of carriers together, so that each user can obtain more resources, and further, higher data transmission rate and better user experience are obtained. The more carriers are aggregated, the more resources can be obtained by the user, and further the higher performance can be obtained. However, in the conventional carrier aggregation scheme, in order to make CA of m+m, m+h, the antennas are separated from each other, and in particular, b1+b3 of m+m, a relatively expensive quad is required. The quad is nearly $ 0.55, which is a relatively considerable and non-trivial design cost.

To this end, referring to fig. 3, the present application discloses a radio frequency system comprising: the device comprises a transceiver chip, a first antenna, a first duplexer and a second duplexer;

In this embodiment, the first antenna may be a middle-high frequency band antenna, configured to receive an external middle-high frequency band radio frequency signal, and send the external middle-high frequency band radio frequency signal to the coupler, where the coupler may be configured to match or adapt impedances between different circuits or systems, that is, to achieve impedance matching between the antenna and a subsequent circuit, where the first duplexer is a duplexer of a first frequency band signal, and is configured to output the first frequency band radio frequency signal to the transceiver chip, and the second duplexer is a duplexer of a second frequency band signal, and is configured to output the second frequency band radio frequency signal to the transceiver chip, so that the first frequency band signal or the second frequency band signal may be selectively output to the transceiver chip by selecting the first duplexer or the second duplexer.

It can be understood that the application replaces the quadruplex in the conventional carrier aggregation scheme with the first duplexer and the second duplexer, and can utilize redundant communication channels of the transceiver chip to achieve the purpose of adding the CA auxiliary channel by adding the auxiliary antenna and receiving the saw of the corresponding frequency band, so that the cost of the quadruplex is reduced while the inter-band carrier aggregation of different frequency bands (such as B1 frequency band and B3 frequency band) can still be realized. Specifically, the coupler may be controlled to be electrically connected to the first duplexer, so that the first duplexer outputs a first frequency band signal, and the auxiliary antenna is controlled to be electrically connected to a corresponding receiving saw, so that the corresponding receiving saw outputs a second frequency band signal, and thus the transceiver chip receives the first frequency band signal and the second frequency band signal to implement inter-band carrier aggregation of the first frequency band and the second frequency band. Similarly, the inter-band carrier aggregation of the first frequency band and the second frequency band can be realized in reverse, specifically, the coupler and the second duplexer can be controlled to be electrically connected, so that the second duplexer outputs the second frequency band signal, and meanwhile, the auxiliary antenna is controlled to be electrically connected with the corresponding receiving saw, so that the corresponding receiving saw outputs the first frequency band signal, and the transceiver chip receives the first frequency band signal and the second frequency band signal to realize the inter-band carrier aggregation of the first frequency band and the second frequency band.

In this way, the first gating circuit can be controlled to selectively connect the first duplexer or the second duplexer, so as to selectively output the first frequency band signal or the second frequency band signal to the transceiver chip. The auxiliary antenna can also be a middle-high frequency band antenna for receiving external radio frequency signals of a middle-high frequency band, and the second gating circuit can also be realized by selecting a single-pole double-throw switch, a single-pole four-throw switch, a single-pole eight-throw switch and the like for selecting a corresponding receiving saw to be electrically connected with the auxiliary antenna so as to realize the output of signals of the corresponding frequency band. The receiving saw is a surface acoustic wave filter (surface acoustic wave), the first receiving saw is a receiving saw of a first frequency band signal and is used for outputting the radio frequency signal of the first frequency band to the receiving-transmitting chip, and the second receiving saw is a duplexer of a second frequency band signal and is used for outputting the radio frequency signal of the second frequency band to the receiving-transmitting chip, so that the first receiving saw or the second receiving saw can be selectively communicated by controlling the second gating circuit, and the first frequency band signal or the second frequency band signal can be selectively output to the receiving-transmitting chip. The additional CA auxiliary channel can be achieved by adding an auxiliary antenna, a second gating circuit and a receiving saw of a corresponding frequency band.

Specifically, the first gating circuit may be controlled, the coupler may be controlled to be electrically connected to the first duplexer, so that the first duplexer outputs a first frequency band signal, and the second gating circuit may be controlled to be electrically connected to the second receiving saw, so that the second receiving saw outputs a second frequency band signal, so that the transceiver chip receives the first frequency band signal and the second frequency band signal to implement inter-band carrier aggregation of the first frequency band and the second frequency band. Similarly, the inter-band carrier aggregation of the first frequency band and the second frequency band can be realized in reverse, specifically, the first gating circuit can be controlled, the control coupler is electrically connected with the second duplexer, so that the second duplexer outputs the second frequency band signal, meanwhile, the second gating circuit is controlled, the auxiliary antenna is controlled to be electrically connected with the first receiving saw, so that the first receiving saw outputs the first frequency band signal, and the transceiver chip receives the first frequency band signal and the second frequency band signal to realize the inter-band carrier aggregation of the first frequency band and the second frequency band.

Specifically, the second gating circuit may control the auxiliary antenna to be electrically connected with the third receiving saw, so that the third receiving saw outputs the B40 band signal to the transceiver chip, and control the first gating circuit to gate the first duplexer or the second duplexer, so that the transceiver chip receives the B1 band signal or the B3 band signal, thereby implementing inter-band carrier aggregation of the B1 band and the B40 band, or implementing inter-band carrier aggregation of the B3 band and the B40 band. Therefore, the third receiving saw is arranged to output the B40 frequency band signal to the receiving-transmitting chip, so that the receiving-transmitting chip can realize the inter-band carrier aggregation of the B1 frequency band and the B3 frequency band, and can also realize the inter-band carrier aggregation of the B1 frequency band and the B40 frequency band, or realize the inter-band carrier aggregation of the B3 frequency band and the B40 frequency band, thereby meeting different application requirements of users and improving the diversity and the practicability of the radio frequency system.
