Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 inventive step, are within the scope of the present disclosure.

The transceiver and the signal processing method provided by the embodiment of the application can be used in electronic equipment, wherein the electronic equipment is provided with a radio frequency signal transceiver (hereinafter referred to as transceiver) which has a carrier aggregation function.

As shown in fig. 1, a schematic structural diagram of a transceiver device provided in an embodiment of the present application may include:

a duplexer 101, a receiving filter 102, a main set antenna 103, a diversity antenna 104, and a path selection module 105; wherein,

the transceiver apparatus of the present application includes at least two duplexers 101 and at least two receiving filters 102, where the duplexers 101 have corresponding receiving filters 102, and the number of the duplexers 101 and the receiving filters 102 is the same, that is, the duplexers 101 and the receiving filters 102 correspond to each other one by one. For convenience of description, the number of duplexers 101 may be denoted as N, and the number of reception filters 102 is also N, where N is a positive integer greater than 1.

Different duplexers 101 correspond to different frequency bands, and each duplexer 101 and the corresponding receiving filter 102 correspond to the same frequency band.

The duplexer 101 may be used for both reception and transmission of radio frequency signals. Therefore, each duplexer 101 may be used for transceiving radio frequency signals of one frequency band, and different duplexers 101 may be used for transceiving radio frequency signals of different frequency bands. That is, the operating frequency band of each duplexer 101 is a single frequency band, and the operating frequency bands of different duplexers 101 are different.

The receiving filters 102 are only used for receiving radio frequency signals, so each receiving filter 102 can be used for receiving radio frequency signals of one frequency band, and different receiving filters 102 can be used for receiving radio frequency signals of different frequency bands. That is, the operating frequency band of the receiving filter 102 is a single frequency band, and the operating frequency bands of different receiving filters 102 are different.

The main set antenna 103 is used for receiving or transmitting radio frequency signals of multiple frequency bands.

The transceiving means of the present application comprises at least two diversity antennas 104. Each diversity antenna 104 may be used for reception of radio frequency signals of one frequency range, or each diversity antenna 104 may be used for reception of radio frequency signals of at least two frequency ranges, or a partial diversity antenna 104 may be used for reception of radio frequency signals of a single frequency range and a partial diversity antenna 104 may be used for reception of radio frequency signals of at least two frequency ranges. For convenience of description, the number of diversity antennas 104 may be denoted as M, which is a positive integer greater than 1. Each frequency range may contain one or more frequency bands, with different frequency ranges containing different frequency bands.

As an example, the different frequency ranges here may be at least two frequency ranges of low frequency, intermediate frequency and high frequency.

As an example, the different frequency ranges may also be different sub-frequency ranges within the same frequency range, for example, the different frequency ranges may be different sub-frequency ranges within the low frequency range; alternatively, the different frequency ranges may be different sub-frequency ranges within the intermediate frequency range, or the different frequency ranges may be different sub-frequency ranges within the high frequency range.

As an example, the different frequency ranges may include different frequency ranges and different sub-frequency ranges of the same frequency range, for example, the different frequency ranges include: a plurality of sub-frequency ranges within the low frequency range and a mid frequency range.

The number of frequency bands in which the M diversity antennas 104 can receive radio frequency signals is the same as the number of frequency bands in which the main set antenna 103 can receive radio frequency signals. That is, the frequency range that can be received by the M diversity antennas 104 is the same as the frequency range that can be received by the main set antenna 103.

The path selection module 105 is configured to:

a first duplexer in the selective duplexer 101 is communicated with a main antenna 103;

selecting at least one second duplexer to communicate with a corresponding diversity antenna 104, respectively; the diversity antenna 104 corresponding to the second duplexer means the diversity antenna 104 whose reception band includes the operating band of the second duplexer.

The receive filter 102 corresponding to the first duplexer and the receive filter 102 corresponding to each second duplexer are selected to be in communication with the corresponding diversity antenna 104. The diversity antenna 104 corresponding to the reception filter 102 is a diversity antenna 104 whose reception band includes the operating band of the reception filter 102.

As an example, one second duplexer may be selected to communicate with the corresponding diversity antenna 104, and the frequency band corresponding to the first duplexer and the frequency band corresponding to the second duplexer are two different frequency bands for carrier combination. That is, when carrier aggregation is performed for signals of two frequency bands, only one second duplexer is selected.

As an example, two second duplexers may be selected to communicate with the corresponding diversity antenna 104, and then the frequency band corresponding to the first duplexer and the frequency bands corresponding to the two second duplexers are three different frequency bands for carrier combination. That is, in carrier aggregation for signals of three frequency bands, two second duplexers need to be selected.

The duplexer 101 and the receiving filter 102 are both connected to the transceiver, so that the duplexer 101 and the receiving filter 102 process the received signals and transmit the processed signals to the transceiver, the transceiver combines the received signals in the same frequency band, thereby improving the anti-fading effect of the radio-frequency signals in the same frequency band, and the transceiver further performs carrier aggregation processing on the signals in different frequency bands to improve the transmission bandwidth of the radio-frequency signals. The particular manner in which the transceiver operates is not material to the present application and will not be described in detail herein.

The transceiver provided by the embodiment of the application can realize the carrier aggregation function through the duplexer and the receiving filter without a quadruplex and a double receiving filter, thereby reducing the volume and the cost of the transceiver.

In an alternative embodiment, the diversity antenna 104 in communication with the second duplexer is different from the diversity antenna 104 in communication with the receive filter 102.

For example, carrier aggregation of two frequency bands, Bx1 and By1, is to be implemented, where Bx1 is a primary carrier, and By1 is a secondary carrier. The path selection module 105 may select the duplexer 101 with the operating frequency band Bx1 as a first duplexer to communicate with the main set antenna 103; a duplexer 101 with the operating frequency band of By1 is selected as a second duplexer to be communicated with a diversity antenna 104 (denoted as a first diversity antenna) with the receiving frequency band of By 1; a receiving filter 102 with the selected working frequency band Bx1 is communicated with a diversity antenna 104 with the receiving frequency band including Bx 1; the receive filter 102 with the selected operating band By1 is connected to another diversity antenna 104 (denoted as second diversity antenna) with the receive band including By 1. The first diversity antenna and the second diversity antenna are two diversity antennas.

For another example, carrier aggregation of three frequency bands of Bx1, By1, and Bz1 is to be implemented, where Bx1 is a primary carrier, and By1 and Bz1 are both secondary carriers. The path selection module 105 may select the duplexer 101 with the operating frequency band Bx1 as a first duplexer to communicate with the main set antenna 103; a duplexer 101 with the operating frequency band of By1 is selected as a second duplexer to be communicated with a diversity antenna 104 (marked as a first diversity antenna) with the receiving frequency band of By 1; a duplexer 101 with an operating frequency band of Bz1 is selected as another second duplexer to be communicated with a diversity antenna 104 (denoted as a second diversity antenna) with a receiving frequency band including Bz 1; a receiving filter 102 with the selected working frequency band Bx1 is communicated with a diversity antenna 104 with the receiving frequency band including Bx 1; a receiving filter 102 with an operating frequency band By1 is selected to be communicated with another diversity antenna 104 (denoted as a third diversity antenna) with a receiving frequency band including By 1; a receive filter 102 with an operating band Bz1 is selected to communicate with another diversity antenna 104 (denoted as a fourth diversity antenna) with a receive band including Bz 1. The first diversity antenna and the third diversity antenna are two independent antennas; the second diversity antenna and the fourth diversity antenna are two independent antennas.

In an optional embodiment, the N duplexers 101 include different sets of duplexers, and the sets of duplexers respectively correspond to different sets of frequency bands. The first duplexer and each second duplexer belong to different sets of duplexers.

That is to say, each duplexer set corresponds to one frequency band set, and the frequency band sets corresponding to different duplexer sets are different, that is, the intersection of the frequency band sets corresponding to different duplexer sets is empty.

As an example, the number of duplexer sets included in the N duplexers 101 may be determined according to the number of frequency bands used for carrier aggregation. For example, if the carrier aggregation is based on two frequency bands, the N duplexers 101 include two sets of duplexers. If the carrier aggregation is performed based on three frequency bands, or, although the carrier aggregation is performed based on two frequency bands, the frequency bands of the carrier aggregation include a frequency band combination in the same frequency band range and frequency bands in different frequency band ranges, the N duplexers 101 include three duplexer sets.

As an example, the frequency bands may be grouped according to the carrier frequency band aggregation characteristics, for example, for the frequency range of low frequencies (600MHz to 960MHz), there are B8+ B20, B8+ B28, B20+ B28, B5+ B12, B5+ B13, B5+ B29, B5+ B28, and the like, which are commonly used in some regions (countries). Through analysis, one part of the combinations is concentrated in the range of 800MHz-960MHz, such as B8 and B5 frequency bands, the other part is concentrated in the range of 600MHz-800MHz, such as B20, B28, B12, B13 and B29 frequency bands, therefore, B8 and B5 can be grouped into one group, and B20, B28, B12, B13 and B29 can be grouped into one group by taking 800MHz as a boundary. The frequency ranges for the medium and high frequencies may also be determined based on the above.

The band grouping of the carrier aggregation in the above example is to group bands in the same frequency range, for example, to group bands in a low frequency range (600MHz to 960MHz), to group bands in a medium frequency range (1700MHz to 2200MHz), or to group bands in a high frequency range (2300MHz to 2700 MHz).

In some scenarios, there may also be combinations of frequency bands within different frequency ranges, such as a combination of low frequency + medium frequency, a combination of low frequency + high frequency, a combination of medium frequency + high frequency, etc. In this scenario, the frequency bands may be grouped according to different frequency ranges, for example, for a combination of low frequency + intermediate frequency, the frequency bands belonging to the low frequency range may be grouped into one group, and the frequency bands belonging to the intermediate frequency range may be grouped into one group.

In some scenarios, there may be a combination of frequency bands in the same range and a combination of frequency bands in different ranges, for example, there may be a combination of frequency bands in low frequency + low frequency and a combination of frequency bands in low frequency + intermediate frequency, and at this time, the frequency bands in the low frequency range may be divided into two groups, and the frequency bands in the intermediate frequency range may be divided into one group, or three groups in total.

In some scenarios, there may be three frequency band combinations in different ranges, such as a combination of low frequency + intermediate frequency, and at this time, the frequency bands in the low frequency range may also be divided into two groups, and the frequency bands in the intermediate frequency range may be divided into one group, and three groups in total.

In an alternative embodiment, the path selection module 105 may include a first selection module and a second selection module; wherein,

the first selection module is configured to communicate the first duplexer with the main set antenna 103, and communicate at least one second duplexer with the corresponding diversity antenna 104.

The second selection module is configured to connect the receive filter 102 corresponding to the first duplexer and the receive filter 102 corresponding to each second duplexer to the corresponding diversity antenna 104.

In an alternative embodiment, the first selection module may include: the duplexer comprises a first switch and at least two second switches, wherein each second switch corresponds to a duplexer set; wherein,

the first switch is used for establishing the corresponding connection relationship between the main set antenna 103 and the diversity antenna 104 corresponding to the second duplexer and the second switch. Specifically, the first switch is used to establish a corresponding connection relationship between the main set antenna 103 and one of the second switches, and a connection relationship between the diversity antenna 104 corresponding to the second duplexer and the other second switches. As an example, the first switch may be a multi-pole, multi-throw switch.

The second switch is used to select one duplexer 101 in the corresponding duplexer set to connect with the first switch. As an example, the second switch may be a single-pole multi-throw switch, a moving end of the single-pole multi-throw switch is connected to the first switch, and at least a part of stationary end connections of the single-pole multi-throw switch are connected in a one-to-one correspondence with the duplexers 101 in the corresponding duplexer set, that is, each duplexer 101 in the duplexer set is connected to one stationary end of the single-pole multi-throw switch.

In an alternative embodiment, the second selection module may include at least two fourth switches; one for each fourth switch, a corresponding set of receive filters. Since the receiving filters correspond to the duplexers one to one, the receiving filter set corresponds to the duplexer set one to one. Wherein,

the fourth switch is used to select one receive filter 102 in the corresponding receive filter set to be connected to the corresponding diversity antenna. As an example, the fourth switch may be a single-pole multi-throw switch, and the moving end of the single-pole multi-throw switch may be directly connected to the corresponding diversity antenna, or the corresponding diversity antenna may be connected through another switch, and at least a part of the stationary ends of the single-pole multi-throw switch are connected to the receiving filters 102 in the corresponding receiving filter set in a one-to-one correspondence, that is, each receiving filter 102 in the receiving filter set is connected to one stationary end of the corresponding single-pole multi-throw switch.

Fig. 2 is a schematic structural diagram of another transceiver device according to an embodiment of the present disclosure. In this example, a total of n + m duplexers 101 are divided into two duplexer sets, where a frequency band included in a frequency band set corresponding to one duplexer set is Bx1 to Bxn, and a frequency band included in a frequency band set corresponding to the other duplexer set is By1 to Bym. n and m may be the same or different.

Taking the duplexer 1 as an example, Bx1 TX corresponding to the duplexer 1 indicates that the duplexer 1 can receive signals of Bx1 band transmitted by the transceiver, and Bx1 RX indicates that the duplexer 1 can transmit signals of Bx1 band to the transceiver. Taking the receiving filter 1 as an example, Bx1 RX corresponding to the receiving filter 1 indicates that the receiving filter 1 can transmit signals in Bx1 frequency band to the transceiver.

The diversity antennas include 3, diversity antenna 1, diversity antenna 2 and diversity antenna 3.

The main set antenna and the diversity antenna 1 are all full-band receiving antennas, that is, the frequency bands which can be received By the main set antenna include Bx 1-Bxn and By 1-Bym; the frequency bands that can be received By the diversity antenna 1 also include Bx1 to Bxn and By1 to Bym.

The frequency band that diversity antenna 2 can receive includes Bx1 Bxn only.

The frequency band that the diversity antenna 3 can receive includes only By 1-Bym.

The first switch is a double pole double throw switch.

The transceiving apparatus shown in fig. 2 may be used for carrier aggregation of two frequency bands. For example, to implement the carrier aggregation of the Bx1 and By1 frequency bands, assuming that Bx1 is the primary carrier and By1 is the secondary carrier, based on the present application,

a first selection module in the path selection module 105 may connect the main set antenna with the second switch 1 through the first switch, connect the diversity antenna 1 with the second switch 2 through the first switch, select the duplexer 1 as a first duplexer to connect with the first switch through the second switch 1, implement that the duplexer 1 communicates with the main set antenna, select the duplexer n +1 as a second duplexer to connect with the first switch through the second switch 2, implement that the duplexer n +1 communicates with the diversity antenna 1;

the second selection module in the path selection module 105 may select the receiving filter 1 to connect to the diversity antenna 2 through the fourth switch 1, and select the receiving filter n +1 to connect to the diversity antenna 3 through the fourth switch 2.

Thus, the radio frequency signal received by the main set antenna reaches the duplexer 1 through the first switch and the second switch 1, and a branch Bx1 frequency band signal output by the duplexer 1 is obtained and sent to the transceiver.

The radio frequency signal received By the diversity antenna 1 reaches the duplexer n +1 through the first switch and the second switch 2, and a By1 frequency band signal output By the duplexer n +1 is obtained and sent to the transceiver.

The radio frequency signal received by the diversity antenna 2 reaches the receiving filter 1 through the fourth switch 1, and the other branch Bx1 frequency band signal output by the receiving filter 1 is obtained and sent to the transceiver.

The radio frequency signal received By the diversity antenna 3 reaches the receiving filter n +1 through the fourth switch 2, and the other path of signal in the By1 frequency band output By the receiving filter n +1 is obtained and sent to the transceiver.

And the transceiver carries out carrier aggregation processing on the two received signals of the Bx1 frequency band and the two signals of the By1 frequency band to obtain signals after carrier aggregation.

For another example, taking carrier aggregation of the Bx1 and By1 bands as an example, assuming that By1 is the primary carrier and Bx1 is the secondary carrier, based on the present application,

a first selection module in the path selection module 105 may connect the main set antenna with the second switch 2 through the first switch, connect the diversity antenna 1 with the second switch 1 through the first switch, and select the duplexer n +1 as a first duplexer to connect with the first switch through the second switch 2, so as to implement communication between the duplexer n +1 and the main set antenna, and select the duplexer 1 as a second duplexer to connect with the first switch through the second switch 1, so as to implement communication between the duplexer 1 and the diversity antenna 1;

Therefore, radio-frequency signals received By the main set antenna reach the duplexer n +1 through the first switch and the second switch 2, a By1 frequency band signal output By the duplexer n +1 is obtained, and the signal is sent to the transceiver.

The radio frequency signal received by the diversity antenna 1 reaches the duplexer 1 through the first switch and the second switch 1, and a branch of Bx1 frequency band signal output by the duplexer 1 is obtained and sent to the transceiver.

As shown in fig. 3, a schematic structural diagram of a transceiver device provided in this embodiment of the present application is shown, in this exemplary diagram, a total of n + m + k duplexers 101 is divided into three duplexer sets, where frequency bands included in a frequency band set corresponding to one duplexer set are Bx1 to Bxn, frequency bands included in a frequency band set corresponding to another duplexer set are By1 to Bym, and frequency bands included in a frequency band set corresponding to a third duplexer set are Bz1 to Bzk. Wherein n, m and k may be the same or different.

The diversity antennas include 5, diversity antenna 1, diversity antenna 2, diversity antenna 3, diversity antenna 4, and diversity antenna 5.

The main set antenna, the diversity antenna 1 and the diversity antenna 3 are all full-band receiving antennas, that is, the frequency bands which can be received By the main set antenna include Bx 1-Bxn, By 1-Bym and Bz 1-Bzk; the frequency bands receivable By the diversity antenna 1 also include Bx1 to Bxn, By1 to Bym and Bz1 to Bzk, and the frequency bands receivable By the diversity antenna 2 also include Bx1 to Bxn, By1 to Bym and Bz1 to Bzk.

The frequency band that diversity antenna 3 can receive includes Bx1 Bxn only.

The frequency band that can be received By the diversity antenna 4 includes only By1 to Bym.

The frequency band that the diversity antenna 5 can receive includes only Bz 1-Bzk.

The first switch is a three-pole three-throw switch.

The transceiver shown in fig. 3 may be used for carrier aggregation of two frequency bands, and may also implement carrier aggregation of three frequency bands. The process of implementing carrier aggregation of two frequency bands may refer to the foregoing embodiments, and is not described herein again. The following describes a process for implementing carrier aggregation of three frequency bands, for example, to implement carrier aggregation of Bx1, By1, and Bz1 frequency bands, assuming that Bx1 is a primary carrier, and By1 and By1 are secondary carriers, based on the present application,

a first selection module in the path selection module 105 may connect the main set antenna with the second switch 1 through the first switch, connect the diversity antenna 1 with the second switch 2 through the first switch, connect the diversity antenna 2 with the second switch 3 through the first switch, and select the duplexer 1 as the first duplexer through the second switch 1, select the duplexer n +1 as a second duplexer through the second switch 2, and select the duplexer n + m +1 as another second duplexer through the second switch 3;

the second selection module in the path selection module 105 may select the receiving filter 1 to connect to the diversity antenna 3 through the fourth switch 1, select the receiving filter n +1 to connect to the diversity antenna 4 through the fourth switch 2, and select the receiving filter n + m +1 to connect to the diversity antenna 5 through the fourth switch 3.

The radio frequency signal received by the diversity antenna 2 reaches the duplexer n + m +1 through the first switch and the second switch 3, and a path of Bz1 frequency band signal output by the duplexer n + m +1 is obtained and sent to the transceiver.

The radio frequency signal received by the diversity antenna 3 reaches the receiving filter 1 through the fourth switch 1, and the other branch Bx1 frequency band signal output by the receiving filter 1 is obtained and sent to the transceiver.

The radio frequency signal received By the diversity antenna 4 reaches the receiving filter n +1 through the fourth switch 2, and the other path of signal in the By1 frequency band output By the receiving filter n +1 is obtained and sent to the transceiver.

The radio frequency signal received by the diversity antenna 5 reaches the receiving filter n + m +1 through the fourth switch 3, and the other path of signal of the Bz1 frequency band output by the receiving filter n + m +1 is obtained and sent to the transceiver.

And the transceiver carries out carrier aggregation processing on the two received signals of the Bx1 frequency band, the two signals of the By1 frequency band and the two signals of the Bz1 frequency band to obtain signals after carrier aggregation.

In an optional embodiment, the second selection module may further include a third switch, and the third switch is configured to establish a connection relationship between the diversity antenna 104 corresponding to the reception filter 102 corresponding to the first duplexer and the reception filter 102 corresponding to each second duplexer, and the at least two fourth switches. That is, the third switch is used to establish a connection relationship between the diversity antenna 104 corresponding to the reception filter and the fourth switch.

The first switch in the first selection module is further configured to: and establishing a connection relationship between at least part of the diversity antennas 104 corresponding to the receiving filter 102 corresponding to the first duplexer and the receiving filter 102 corresponding to each second duplexer and the third switch.

That is, the second selection module shares the first switch with the first selection module. Thus, in some cases, the connection relationship between the diversity antenna corresponding to the duplexer and the receiving filter 102 may be established through the first switch, for example, when the carrier aggregation function is not used, but only the diversity receiving function of a single frequency band (for example, a Bx2 frequency band) is needed, only signals need to be received through the main set antenna 103 and the diversity antenna 104 whose receiving frequency band includes Bx2, respectively, and based on this embodiment, the connection relationship between the main set antenna 103 and a second switch may be established through the first switch, and the connection relationship between the diversity antenna 104 corresponding to the duplexer whose operating frequency band is not Bx2 (the receiving frequency band of the diversity antenna 104 includes Bx2) and a third switch may be established through the second switch, so that the connection relationship between the main set antenna 103 and the duplexer whose operating frequency band is Bx2, and the connection relationship between the diversity antenna 104 corresponding to the duplexer whose operating frequency band is not Bx2 and the receiving filter whose operating frequency band is Bx2 may be established through the second switch, and single-frequency-band diversity reception is realized. Due to the limited space of the electronic device, in the multiple diversity antennas, the performance (e.g., anti-noise capability, gain, etc.) of the diversity antenna corresponding to the duplexer is generally better than the performance of the diversity antenna corresponding to the receive filter, and therefore, in a single-band diversity reception scenario, the performance of single-band diversity reception may be improved by connecting the diversity antenna corresponding to the duplexer to the receive filter.

Fig. 4 is a schematic structural diagram of a transceiver device according to an embodiment of the present application. Fig. 4 is a modified scheme of the scheme shown in fig. 2, and differs from fig. 2 in that a third switch is added to the second selection module, and the first switch in the first selection module is replaced by a three-pole three-throw switch, and the diversity antenna 2 is not directly connected to the fourth switch 1, but is connected to the fourth switch 1 through the first switch and the third switch.

The transceiving apparatus shown in fig. 4 may be used for carrier aggregation of two frequency bands. For example, to implement the carrier aggregation of the Bx1 and By1 frequency bands, assuming that Bx1 is the primary carrier and By1 is the secondary carrier, based on the present application,

a first selection module in the path selection module 105 may connect the main set antenna with the second switch 1 through the first switch, connect the diversity antenna 1 with the second switch 2 through the first switch, connect the diversity antenna 2 with the third switch through the first switch, and select the duplexer 1 as a first duplexer through the second switch 1, and select the duplexer n +1 as a second duplexer through the second switch 2;

the second selection module in the path selection module 105 may connect the first switch (i.e., the path where the diversity antenna 2 is located) to the fourth switch 1 through the third switch, connect the diversity antenna 3 to the fourth switch 2 through the third switch, select the receiving filter 1 to connect to the third switch (i.e., the path where the diversity antenna 2 is located) through the fourth switch 1, and select the receiving filter n +1 to connect to the third switch (i.e., the path where the diversity antenna 3 is located) through the fourth switch 2.

The radio frequency signal received by the diversity antenna 2 passes through the first switch, the third switch and the fourth switch 1 to reach the receiving filter 1, and the other path of Bx1 frequency band signal output by the receiving filter 1 is obtained and sent to the transceiver.

The radio frequency signal received By the diversity antenna 3 passes through the third switch and the fourth switch 2 to reach the receiving filter n +1, and the other path of signal in the By1 frequency band output By the receiving filter n +1 is obtained and sent to the transceiver.

And the transceiver carries out carrier aggregation processing on the two paths of signals with the Bx1 frequency band and the two paths of signals with the By1 frequency band, so as to obtain signals after carrier aggregation.

The transceiver apparatus shown in fig. 4 can also be used for single-band diversity reception. For example, to implement diversity reception in Bx2 frequency band, then:

a first selection module in the path selection module 105 may connect the main set antenna with the second switch 1 through the first switch, connect the diversity antenna 2 with the third switch through the first switch, and select the duplexer 2 to connect with the first switch (i.e., the path where the main set antenna is located) through the second switch 1.

The second selection module in the path selection module 105 may connect the first switch (i.e., the path where the diversity antenna 2 is located) to the fourth switch 1 through the third switch, and select the receiving filter 2 to connect to the third switch (i.e., the path where the diversity antenna 2 is located) through the fourth switch 1.

Therefore, the radio-frequency signals received by the main set antenna reach the duplexer 2 through the first switch and the second switch 1, and a signal of a Bx2 frequency band output by the duplexer 2 is obtained and sent to the transceiver.

The radio frequency signal received by the diversity antenna 2 reaches the receiving filter 2 through the first switch, the third switch and the fourth switch 1, and the receiving filter 2 outputs another branch Bx2 frequency band signal and sends the signal to the transceiver.

The transceiver synthesizes the received signals of the two Bx2 frequency bands to obtain a synthesized signal.

Based on the transceiver shown in fig. 4, another implementation manner for achieving diversity reception of the Bx2 frequency band may be:

a first selection module in the path selection module 105 may connect the main set antenna with the second switch 1 through the first switch, connect the diversity antenna 1 with the third switch through the first switch, and select the duplexer 2 to connect with the first switch (i.e., the path where the main set antenna is located) through the second switch 1.

A second selection module in the path selection module 105 may connect the first switch (i.e., the path where the diversity antenna 1 is located) to the fourth switch 1 through the third switch, and select the receiving filter 2 to connect to the third switch (i.e., the path where the diversity antenna 1 is located) through the fourth switch 1.

Thus, the radio frequency signal received by the main set antenna reaches the duplexer 2 through the first switch and the second switch 1, and a branch Bx2 frequency band signal output by the duplexer 2 is obtained and sent to the transceiver.

The radio frequency signal received by the diversity antenna 1 reaches the receiving filter 2 through the first switch, the third switch and the fourth switch 1, and the receiving filter 2 outputs another branch Bx2 frequency band signal and sends the signal to the transceiver.

In general, the performance of the diversity antenna 1 is better than the performance of the diversity antenna 2 and the diversity antenna 3, and therefore, based on the scheme shown in fig. 4, the performance of single-band diversity reception can be improved. Compared with the scheme shown in fig. 2, the method has more ways of realizing single-frequency-band diversity reception, and improves the fault resistance of the electronic equipment.

In the above embodiment, the diversity antennas corresponding to different sets of receiving filters are different, that is, different fourth switches are connected to different diversity antennas.

As shown in fig. 2 and 4. The reception filters 1 to n correspond to the diversity antennas 2, and the reception filters n +1 to n + m correspond to the diversity antennas 3.

In some embodiments, the diversity antennas for different sets of receive filters may also be the same. Based on this, the diversity antenna corresponding to the receiving filter corresponding to the first duplexer and the receiving filter corresponding to each second duplexer in the present application at least includes a target diversity antenna, and the receiving frequency band of the target diversity antenna includes at least two frequency band sets; the second selection module further comprises a frequency divider; the frequency divider can be a chip or a circuit built by components.

The frequency divider is connected with the target diversity antenna and used for carrying out frequency division processing on the signals received by the target diversity antenna so as to output signals of at least two frequency ranges. Signals of different frequency ranges contain frequency bands in different sets of frequency bands.

And the output end of the frequency divider is communicated with the corresponding fourth switch.

As an example, the output of the frequency divider is directly connected to the corresponding fourth switch. Or,

the output end of the frequency divider is connected with a corresponding fourth switch through a first switch and a third switch; or,

and part of output ends of the frequency dividers are connected with the corresponding fourth switches through the first switches and the third switches, and part of output ends of the frequency dividers are connected with the corresponding fourth switches through the third switches.

Fig. 5 is a schematic structural diagram of a transceiver apparatus provided in the embodiment of the present application, where fig. 5 is an improvement on fig. 2, and differs from fig. 2 in that a frequency divider is added and a diversity antenna is reduced, and a receiving frequency band of the diversity antenna 2 in fig. 5 also includes: bx 1-Bxn and By 1-Bym.

Based on the embodiment shown in fig. 5, for example, to implement carrier aggregation of the Bx1 and By1 frequency bands, assuming that Bx1 is the primary carrier and By1 is the secondary carrier, based on the present application,

a first selection module in the path selection module 105 may connect the main antenna and the second switch 1 through the first switch, connect the diversity antenna 1 and the second switch 2 through the first switch, select the duplexer 1 as a first duplexer through the second switch 1, and select the duplexer n +1 as a second duplexer through the second switch 2;

a second selection module in the path selection module 105 divides the frequency of the radio frequency received by the diversity antenna 2 by the frequency divider to obtain radio frequency signals in two frequency ranges, wherein one of the radio frequency signals is output to the fourth switch 1, the other radio frequency signal is output to the fourth switch 2, the fourth switch 1 selects the receiving filter 1 to be connected with one output end of the frequency divider, and the fourth switch 2 selects the receiving filter n +1 to be connected with the other output end of the frequency divider.

The radio frequency signal received By the diversity antenna 1 reaches the duplexer n +1 through the first switch and the second switch 2, so that a By1 frequency band signal output By the duplexer n +1 is obtained and sent to the transceiver.

The radio frequency signal received by the diversity antenna 2 reaches the receiving filter 1 through the frequency divider and the fourth switch 1, and the other path of Bx1 frequency band signal output by the receiving filter 1 is obtained and sent to the transceiver.

The radio frequency signal received By the diversity antenna 2 reaches the receiving filter n +1 through the frequency divider and the fourth switch 2, and the other path of signal in the By1 frequency band output By the receiving filter n +1 is obtained and sent to the transceiver.

And if the diversity antenna corresponding to the receiving filter corresponding to the first duplexer and the receiving filter corresponding to each second duplexer also comprise a non-target diversity antenna, the non-target diversity antenna is connected with the first switch or the third switch or the fourth switch. That is, the non-target diversity antenna may be directly connected with the corresponding fourth switch, or the non-target diversity antenna may be connected with the corresponding fourth switch through the first switch and the third switch, or the non-target diversity antenna may be connected with the corresponding fourth switch through the third switch.

As shown in fig. 6, for another structural schematic diagram of a transceiver apparatus provided in the embodiment of the present application, fig. 6 is an improvement on fig. 4, and differs from fig. 4 in that a frequency divider is added and a diversity antenna is reduced, and a receiving frequency band of the diversity antenna 2 in fig. 6 also includes: bx 1-Bxn and By 1-Bym.

Based on the embodiment shown in fig. 6, for example, to implement carrier aggregation of the Bx1 and By1 frequency bands, assuming that Bx1 is the primary carrier and By1 is the secondary carrier, based on the present application,

a first selection module in the path selection module 105 may connect the main set antenna with the second switch 1 through the first switch, connect the diversity antenna 1 with the second switch 2 through the first switch, connect one output end of the frequency divider with the third switch through the first switch, select the duplexer 1 as the first duplexer through the second switch 1, and select the duplexer n +1 as the second duplexer through the second switch 2;

a second selection module in the path selection module 105 may connect the diversity antenna 2 with the first switch and the third switch through the frequency divider, connect the first switch (i.e., a path where one path of output of the frequency divider is located) with the fourth switch 1 through the third switch, connect the frequency divider (i.e., a path where another path of output of the frequency divider is located) with the fourth switch 2 through the third switch, select the receiving filter 1 to connect with the third switch (i.e., a path where one path of output of the frequency divider is located) through the fourth switch 1, and select the receiving filter n +1 to connect with the third switch (i.e., a path where another path of output of the frequency divider is located) through the fourth switch 2.

The radio frequency signal received by the diversity antenna 2 passes through the frequency divider, the first switch, the third switch and the fourth switch 1 to reach the receiving filter 1, and the other path of Bx1 frequency band signal output by the receiving filter 1 is obtained and sent to the transceiver.

The radio frequency signal received By the diversity antenna 2 passes through the second frequency divider and the third switch, the fourth switch 2 reaches the receiving filter n +1, and the other path of signal in the By1 frequency band output By the receiving filter n +1 is obtained and sent to the transceiver.

Fig. 7 is a schematic structural diagram of a transceiver apparatus according to an embodiment of the present application, where fig. 7 is a modified structure of fig. 3, and differs from fig. 3 in that a frequency divider is added and a diversity antenna is reduced, and a receiving frequency band of the diversity antenna 4 in fig. 7 includes: by 1-Byn and Bz 1-Bzk.

For example, to implement carrier aggregation of the Bx1, By1, and Bz1 frequency bands, assuming that Bx1 is the primary carrier and By1 and By1 are the secondary carriers, based on the present application,

the second selection module in the path selection module 105 may select the receiving filter 1 to be connected to the diversity antenna 3 through the fourth switch 1, connect the diversity antenna 4 to the fourth switch 2 and the fourth switch 3 through the frequency divider, connect one output terminal of the frequency divider to the fourth switch 2, connect one output terminal to the fourth switch 3, select the receiving filter n +1 to be connected to one output terminal of the frequency divider through the fourth switch 2, and select the receiving filter n + m +1 to be connected to the other output terminal of the frequency divider through the fourth switch 3.

Therefore, the radio frequency signal received by the main set antenna reaches the duplexer 1 through the first switch and the second switch 1, and a signal of Bx1 frequency band output by the duplexer 1 is obtained and sent to the transceiver.

The radio frequency signal received By the diversity antenna 4 reaches the receiving filter n +1 through the frequency divider and the fourth switch 2, and the other path of signal in the By1 frequency band output By the receiving filter n +1 is obtained and sent to the transceiver.

The radio frequency signal received by the diversity antenna 4 reaches the receiving filter n + m +1 through the frequency divider and the fourth switch 3, and the other path of Bz1 frequency band signal output by the receiving filter n + m +1 is obtained and sent to the transceiver.

In an alternative embodiment, the diversity antenna 3 shown in fig. 7 may also be connected to the fourth switch 1 not directly, but through the first switch, in which case the first switch may be replaced by a four-pole four-throw switch. In this way, the diversity antenna 1 or the diversity antenna 2 can achieve single-band diversity reception in the reception frequency range corresponding to the diversity antenna 3, thereby increasing the diversity reception mode.

In an alternative embodiment, a third switch (e.g., a double pole double throw switch) may also be added to the second selection module shown in fig. 7, and then,

one of the outputs of the diversity antenna 3 and the frequency divider shown in fig. 7 may be connected to a third switch added through the first switch (at this time, the first switch becomes a five-pole five-throw switch), the third switch is also connected to the fourth switch 1 and the fourth switch 2 (or the third switch is also connected to the fourth switch 1 and the fourth switch 3), so that diversity reception of a single band in the reception frequency range of the diversity antenna 3 and the partial reception frequency range of the diversity antenna 4 can be achieved by the diversity antenna 1 or the diversity antenna 2, and the manner of diversity reception can be increased. Or,

the two outputs of the divider shown in fig. 7 may be connected via a first switch (now the first switch becomes a five-pole five-throw switch) to an additional third switch, which is also connected to a fourth switch 2 and a fourth switch 3, so that diversity reception of a single frequency band within the reception frequency range of the diversity antenna 4 may be achieved via the diversity antenna 1 or the diversity antenna 2, increasing the manner of diversity reception.

In an alternative embodiment, the third switch may also be a three pole, three throw switch, and then,

the diversity antenna 3 and the two outputs of the frequency divider shown in fig. 7 are connected to the added three-pole three-throw switch through the first switch (at this time, the first switch becomes a six-pole six-throw switch), and the three-pole three-throw switch is also connected to the fourth switch 1, the fourth switch 2, and the fourth switch 3, so that it is possible to realize diversity reception of a single frequency band in the reception frequency range of the diversity antenna 3 and the reception frequency range of the diversity antenna 4 by the diversity antenna 1 or the diversity antenna 2, and increase the manner of diversity reception.

In an alternative embodiment, each duplexer 101 is connected to the transceiver through a radio frequency power amplifier, so that the transceiver can transmit signals through the duplexer.

Wherein the first duplexer is coupled to the transceiver via a first rf power amplifier and the second duplexer is coupled to the transceiver via a second rf power amplifier, in an alternative embodiment,

if the working frequency band of the first duplexer and the working frequency band of the second duplexer belong to the working frequency band of the same communication network, the first radio frequency power amplifier is the same as the second radio frequency power amplifier;

and if the working frequency band of the first duplexer and the working frequency band of the second duplexer belong to the working frequency bands of different communication networks, the first radio frequency power amplifier is different from the second radio frequency power amplifier. Based on this, the transceiver can simultaneously transmit signals of different communication networks through the first duplexer and the second duplexer, so as to realize simultaneous transmission and simultaneous reception of signals of different communication networks.

That is, the first duplexer, and at least a portion of the second duplexer, are connected to the transceiver through different rf power amplifiers; the frequency bands corresponding to the first duplexer and at least part of the second duplexer are used for different communication networks. In other words, at least two duplexer sets exist, wherein one duplexer set corresponds to a first frequency band set, at least one duplexer set corresponds to a second frequency band set, and the first frequency band set and the second frequency band set are used for different communication networks;

each duplexer in the duplexer set corresponding to the first frequency band set is connected with the transceiver through a first radio frequency power amplifier, and each duplexer in the corresponding second frequency band set is connected with the transceiver through a second radio frequency power amplifier; the first radio frequency power amplifier and the second radio frequency power amplifier are used for amplifying the power of radio frequency signals of different frequency band sets, and the radio frequency signals are radiated by an antenna after enough radio frequency power is obtained.

As an example, in the case of implementing carrier aggregation based on two frequency bands, a first frequency band set corresponding to one duplexer set belongs to an operating frequency band of a 4G network, and a second frequency band corresponding to another duplexer set belongs to an operating frequency band of a 5G network; or, a first frequency band set corresponding to one duplexer set belongs to the working frequency band of the 5G network, and a second frequency band corresponding to the other duplexer set belongs to the working frequency band of the 4G network; or, a first frequency band set corresponding to one duplexer set belongs to the working frequency band of the 5G network, and a second frequency band corresponding to another duplexer set belongs to the working frequency band of the 6G network, and so on.

As an example, in the case of implementing carrier aggregation based on three frequency bands, a first frequency band set corresponding to one duplexer set belongs to an operating frequency band of a 4G network, a second frequency band set corresponding to one second duplexer set belongs to an operating frequency band of a 5G network, and a second frequency band set corresponding to another second duplexer set belongs to an operating frequency band of a 6G network; or, a first frequency band set corresponding to one duplexer set belongs to the working frequency band of the 4G network, a second frequency band set corresponding to one second duplexer set belongs to the working frequency band of the 4G network, and a second frequency band set corresponding to another second duplexer set belongs to the working frequency band of the 5G network.
