Description

Technical Field

[0002] Based on the demand for carrier aggregation, many integrated devices need to add quadruplicaters / triplexers / duplexers / simplexers and other devices internally to realize the frequency band signals that can be accessed on a single device. However, due to the characteristics of the ASM (Antenna Switch Module) switch connected to the front end of the integrated device, the frequency band signal can only be filtered through a single device to obtain one frequency band, and the ability to aggregate carriers between frequency bands supported by different devices cannot be realized. As a result, conventional carrier aggregation devices have low scalability and cannot meet the needs of carrier aggregation of multiple frequency bands.

However, since this solution introduces new devices on the front end of the ASM switch, it will affect the performance of the connection channel between the antenna array and reduce the transmission performance.

[0037] Reference Figure 1 As shown, Figure 1 The utility model provides a module schematic diagram of a carrier aggregation device, the carrier aggregation device includes a frequency band access module 10;

[0038] The frequency band path module 10 is provided with a phase shifter module 101, and the output end of the phase shifter module 101 is provided with a plurality of frequency band channels L for transmitting frequency band signals;

[0039] The phase shifter module 101 is used to turn on the corresponding frequency band channels L according to the incoming channel control signal, and based on each turned-on frequency band channel L, transmit the accessed frequency band signal to the corresponding turned-on frequency band channel L to obtain different frequency bands for carrier aggregation.

[0040] It should be noted that the frequency band path module 10 provided in the carrier aggregation device in this embodiment can realize the conduction of multiple frequency band channels L, and can also combine and configure the conduction status of each conducted frequency band channel L according to the currently required carrier aggregation combination to obtain the optimal carrier aggregation combination.

[0041] Specifically, the frequency band path module 10 is provided with a phase shifter module 101, and the phase shifter module 101 replaces the ASM switch in the conventional carrier aggregation device.

[0042] Due to the characteristics of the ASM switch, the ASM switch can only conduct one connected frequency band channel L at the same time. Therefore, in order to improve the carrier aggregation capability of the carrier aggregation device and avoid the problem of reduced transmission performance caused by connecting devices such as a diplexer at the front end of the ASM switch, it is proposed to replace the ASM switch with a phase shifter module 101. By using the characteristics of the phase shifter module 101 that multiple connected frequency band channels L can be simultaneously conducted at the same time, and multiple frequency band signals are output to different filter modules 102 for filtering based on the simultaneously conducted frequency band channels L, carrier aggregation of multiple frequency bands is achieved, thereby improving the carrier aggregation capability of the carrier aggregation device, while avoiding the access of devices such as a diplexer, and avoiding the reduction in channel transmission performance between the antenna array 40.

[0043] Specifically, the on-off state of the frequency band channel L of the phase shifter module is controlled by the channel control signal it receives. The channel control signal is generated according to the currently required carrier aggregation combination. After determining the frequency band channel L to which the frequency band required by the currently required carrier aggregation combination belongs based on the currently required carrier aggregation combination and the frequency band that can be filtered by the other end of each frequency band channel L, a channel control signal is generated based on the frequency band channel L to which the frequency band required by the currently required carrier aggregation combination belongs, and the channel control signal is transmitted to the phase shifter module 101. The phase shifter module 101 turns on the frequency band channel L to which the frequency band required by the currently required carrier aggregation combination belongs according to the channel control signal, and transmits the accessed frequency band signal to the corresponding turned-on frequency band channel L to obtain different frequency bands for carrier aggregation.

[0044] Among them, because the phase shifter module 101 avoids the introduction of devices such as diplexers, the structure of the carrier aggregation device avoids major changes, avoids structural complexity, and avoids the defect of being unfavorable for subsequent improvements.

[0045] Furthermore, the frequency band path module 10 also includes multiple filter modules 102, and the multiple filter modules 102 are respectively connected to the output end of the phase shifter module 101, wherein the connection line between the filter module 102 and the phase shifter module 101 forms the frequency band channel L; the filter module 102 is used to filter the frequency band signal transmitted by the conducted frequency band channel L.

[0046] according to Figure 1 It can be seen that the input end side of the phase shifter module 101 is provided with a plurality of filter modules 102, each filter module 102 is respectively connected to the output end of the phase shifter module 101, and the connection line connecting each filter module 102 with the output end of the phase shifter module 101 is a frequency band channel L for transmitting the frequency band signal between each filter module 102 and the phase shifter module 101. Each filter module 102 is used to filter the connected frequency band signal to obtain the frequency band it supports, that is, the target frequency band.

[0047] Furthermore, the carrier aggregation device further includes a control module 20 , and the control module 20 is connected to the frequency band path module 10 .

[0048] Furthermore, the carrier aggregation device further includes a resonance system 30 , and the resonance system 30 is connected to the control module 20 and the frequency band path module 10 respectively.

[0049] according to Figure 1 It can be known that the carrier aggregation device further includes a control module 20 and a resonance system 30 .

[0050] Among them, the control module 20 is connected to the rear end of the frequency band path module 10, and is respectively connected to the frequency band path module 10 and the resonance system 30, and is used to control the on and off of the frequency band channel L that needs to be turned on in the frequency band path module 10, and to control the on and off of different frequency band channels L at different timings, so as to avoid frequency band interference caused by accessing frequency bands that cannot exist at the same time at the same timing, and to control the resonance system 30.

[0051] The resonance system 30 is connected to the front end of the frequency band path module 10, and is respectively connected to the frequency band path module 10 and the control module 20, and is used to transmit the connected frequency band signal and the antenna adjustment signal output by the control module 20 to the phase shifter module 101, and control the resonance system 30 to optimize the antenna performance of the antenna array 40.

[0052] Specifically, refer to Figure 2As shown, the control module 20 includes a transceiver 201, the sending channel of the transceiver 201 is respectively connected to the receiving end of each of the filter modules 102, and the receiving channel of the transceiver 201 is respectively connected to the sending end of each of the filter modules 102, for sending a first signal to each of the filter modules 102, and receiving a target frequency band obtained after each of the filter modules 102 filters the accessed frequency band signal;

[0053] The control end of the transceiver 201 is connected to the phase shifter module 101 through a control line, and is used to generate the channel control signal according to the connected carrier aggregation instruction, and then transmit the channel control signal to the phase shifter module 101 through the control line.

[0054] The control module 20 in this example includes a transceiver 201, which can determine the frequency band of the current communication operation and the required carrier aggregation combination based on the carrier aggregation instruction it receives, and then generate a channel control signal. The channel control signal is transmitted to the phase shifter module 101 through the control end, and the frequency band channel L on the output end of the phase shifter module 101 is controlled to be on and off. After the corresponding frequency band channel L is controlled to be turned on, the frequency band signal is transmitted to the corresponding filter module 102 for filtering the required frequency band. The transceiver 201 can control the phase shifter module 101 to operate on the corresponding frequency band according to the current working frequency band, that is, control the phase shifter module 101 to turn on several frequency band channels L.

[0055] In addition, the transceiver 201 is also connected to the filter module 102. Specifically, the transmission channel of the transceiver 201 is connected to the receiving end of each filter module 102, and is used to send a first signal to each filter module 102, and each filter module 102 filters the connected first signal according to its pre-set center frequency band; at the same time, the receiving channel of the transceiver 201 is connected to the transmission end of each filter module 102, and is used to receive the target frequency band obtained after the filter module 102 filters the frequency band signal, that is, the frequency band supported by the filter module 102.

[0056] Furthermore, the filter module 102 is composed of a plurality of filters, and the input ends of the plurality of filters form an input node connected to the output end of the phase shifter module 101 to form the frequency band channel L.

[0057] When the filter is a receiving filter, the receiving end of the receiving filter is connected to the transmitting channel of the transceiver 201 ; when the filter is a transmitting filter, the transmitting end of the transmitting filter is connected to the receiving channel of the transceiver 201 .

[0058] Figure 2The filter module 102 shown in is an example, in which the filter module 102 includes a quadplexer and a duplexer, etc. The quadplexer is composed of two receiving filters and two transmitting filters; the duplexer is composed of a receiving filter and a transmitting filter.

[0059] It should be noted that, when too many filter modules cannot be connected due to the device design and size problems of the frequency band path module 10, and when some existing frequency bands cannot be supported, the filter module is usually connected to the Aux port (Auxiliary port, auxiliary interface) of the frequency band path module 10, for example Figure 2 The filter module 103 is connected to the phase shifter module 101 through the Aux port of the frequency band path module 10, so that the carrier aggregation device can support the frequency band supported by the filter module 103.

[0060] In conventional carrier aggregation devices, because the ASM switch can only conduct one frequency band channel, only one frequency band channel L connected to a device among the quadplexer, duplexer and simplexer can be conducted to access the frequency band signal, and the quadplexer, duplexer and simplexer cannot simultaneously access the frequency band signal to output different frequency bands for carrier aggregation, which makes the conventional carrier aggregation device have limitations. In this embodiment, by replacing the ASM switch with a phase shifter module 101, based on the characteristic that the phase shifter module 101 can conduct multiple frequency band channels L at the same time, carrier aggregation between the frequency bands supported by the quadplexer, duplexer and simplexer can be achieved, so that the carrier aggregation device can be adapted to various carrier aggregation combination scenarios.

[0061] It should be noted that the composition of the filter module 102 is not limited to Figure 2 The given filter module 102 can be improved according to actual needs, and the improvement will not affect the overall effect of the carrier aggregation device.

[0062] Furthermore, the resonance system 30 includes an antenna resonator 301, a first end of the antenna resonator 301 is connected to the phase shifter module 101, and is used to transmit the received frequency band signal to the phase shifter module 101; the second end of the antenna resonator 301 is connected to the control end of the transceiver 201, and is used to receive the antenna adjustment signal output by the transceiver 201.

[0063] according to Figure 2It can be seen that the resonance system 30 in this example includes an antenna resonator 301, which is controlled by the transceiver 201, and the transceiver 201 controls the antenna resonator 301 to work in the corresponding frequency band according to the current working frequency band. The antenna resonator 301 filters out the clutter interference of the frequency band signal according to the frequency band signal connected to the first end, so as to improve the sensitivity and performance of the antenna array 40 connected to the input adjustment end of the antenna resonator 301. The antenna resonator 301 generates an output control signal for controlling the antenna array 40 according to the antenna adjustment signal connected to the second end, so that the antenna array 40 can adapt to the current working frequency band based on the output control signal.

[0064] Furthermore, the carrier aggregation device further includes an antenna array 40, and the antenna array 40 is connected to the input adjustment end of the antenna resonator 301, and is used to change the frequency range according to the output control signal.

[0065] Depend on Figure 2 It can be seen that the antenna array 40 is connected to the input adjustment end of the antenna resonator 301. According to the output control signal output by the antenna resonator 301, the antenna array 40 adaptively adjusts its frequency range to change the frequency band signal it is connected to. The received frequency band signal is then conditioned and filtered by the antenna resonator 301, and after filtering out clutter interference, it is transmitted to the phase shifter module 101.
