Description

Radio frequency integrated circuit and radio frequency transmitting device

Technical Field

The present application relates to the field of radio frequency technology, and more particularly, to a radio frequency integrated circuit and a radio frequency transmitting device.

Background

With rapid development of radio frequency technology, radio frequency transmission apparatuses for transmitting sounding reference signals (sounding reference signal, SRS) are widely used. In the radio frequency transmitting device provided by the related art, a change-over switch (which may be a single-pole multi-throw switch) is generally arranged between the amplifying module and the transmitting module, and the SRS is switched between different transmitting modules through the change-over switch. However, the arrangement of the switch not only increases the area and cost of the radio frequency transmission device, but also increases the wiring from the switch to the transmission module and the insertion loss of the wiring, which results in an increase in the transmission power consumption of the transmission module, and further increases the transmission power consumption of the radio frequency transmission device.

Therefore, there is a need for a radio frequency transmission device that is small in area, low in cost, and low in transmission power consumption.

Disclosure of Invention

The application provides a radio frequency integrated circuit (radio frequency integrated circuit, RFIC) and a radio frequency transmission device, which not only realize the switching of SRS between different transmission modules, but also reduce the area of the radio frequency transmission device and reduce the cost and the transmission power consumption of the radio frequency transmission device.

In a first aspect, the present application provides an RFIC that may include a switching module, a plurality of digital front end (digital front end, DFE) modules (which may be referred to simply as DFE modules), a plurality of Analog Front End (AFE) modules (which may be referred to simply as AFE modules), and a plurality of radio frequency channels (TX).

Wherein the switching module may be electrically connected to a baseband integrated circuit (baseband integrated circuit, BBIC), the switching module may also be electrically connected to each of the plurality of DFE modules. That is, the input of the switching module may be electrically connected to the output of the BBIC, and the output of the switching module may be electrically connected to the input of each DFE module.

Alternatively, the plurality of DFE modules may be electrically connected to the plurality of AFE modules in a one-to-one correspondence, and the plurality of AFE modules may be electrically connected to the plurality of radio frequency channels in a one-to-one correspondence.

For example, the plurality of DFE modules may include a first DEF module and a second DEF module. The plurality of AFE modules may include a first AFE module and a second AFE module. The plurality of radio frequency channels may include a first radio frequency channel and a second radio frequency channel.

Thus, the output of the first DEF module may be electrically connected to the input of the first AFE module, and the output of the first AFE module may be electrically connected to the first radio frequency channel. Similarly, an output of the second DEF module may be electrically connected to an input of the second AFE module, and an output of the second AFE module may be electrically connected to the second radio frequency channel.

Further, the above-mentioned switching module may be used for: and receiving a Baseband Signal (BS) transmitted by the BBIC. Wherein the BS may include first destination information. The first destination information is used to indicate a transmission destination of the BS. The switching module may also be configured to switch the BS from the first DEF module to the second DEF module based on the first destination information in the case where the transmission destination of the BS is the second radio frequency channel.

It is understood that the BS may input the first DFE module before the handover module performs handover to the BS. After the switching module switches the BS, the BS may then input the second DFE module.

Wherein the first DEF module and the second DEF module belong to a plurality of DEF modules. That is, the plurality of DFE modules may include a first DEF module and a second DEF module. It is conceivable that the first DEF module and the second DEF module are different DFE modules.

The second DFE module may be configured to: and modulating the BS from the switching module to obtain the modulated BS. The second DFE module may also be configured to transmit the modulated BS to the second AFE module.

The second AFE module may be to: the modulated BS transmitted by the second DFE module is converted into a sounding reference signal (sounding reference signal, SRS) and output through the second radio frequency channel.

It is conceivable that the switching module may be further configured to switch the BS from the second DEF module to the first DEF module according to the first destination information, in case the BS is switched by the switching module and the transmission destination of the BS is the first radio frequency channel, that is, the switching module may switch the BS between different DFE modules.

It is understood that the BS may input the second DFE module before the handover module performs handover to the BS. After the switching module switches the BS, the BS may then input the first DFE module.

Thus, similar to the second DFE module, the first DFE module may be configured to: and modulating the BS from the switching module to obtain the modulated BS. The first DFE module may also be configured to transmit the modulated BS to the first AFE module.

Similar to the second AFE module, the first AFE module can be configured to: and converting the modulated BS transmitted by the first DFE module into SRS and outputting the SRS through a first radio frequency channel.

The RFIC provided in the first aspect of the present application may enable the BS to switch from the first DEF module to the second DEF module through the switching module, that is, enable the BS to switch between different DFE modules in a soft manner, and further enable the SRS to switch from the first radio frequency channel to the second radio frequency channel.

In one possible implementation, the switching module may include a baseband interface (baseband interface, BIF).

Further, the BIF may include an input, a first output, and a second output. The input end can be electrically connected with the output end of the BBIC, the first output end can be electrically connected with the input end of the first DEF module, and the second output end can be electrically connected with the input end of the second DEF module.

The input may then receive the BS of BBIC transmissions. The first output may transmit the BS to the first DEF module. The second output may transmit the BS to a second DEF module.

It will be appreciated that the input and the first output may constitute a primary channel of the BIF and the input and the second output may constitute a secondary channel of the BIF. The BS may transmit to the first DFE module through the primary channel, and further output the SRS through the first radio frequency channel. Under the condition that the second radio frequency channel needs to output SRS, the BS can transmit the SRS to the second DFE module through the auxiliary channel, and then the SRS is output through the second radio frequency channel, namely the switching of the SRS between the first output channel and the second output channel is realized.

It is conceivable that the first radio frequency channel and the second radio frequency channel do not output SRS at the same time. That is, in the case where the second radio frequency channel outputs the SRS, the first radio frequency channel does not output the SRS. Otherwise, when the first radio frequency channel outputs the SRS, the second radio frequency channel does not output the SRS.

In another possible implementation manner, the RFIC provided in the first aspect of the application may further include a frequency modulation module. The frequency modulation module may be electrically connected to each of the plurality of AFE modules. For example, the frequency modulation module may be electrically connected to the first AFE module and may also be electrically connected to the second AFE module.

It will be appreciated that the modulated BS may be an input signal of the first AFE module, and the SRS may be an output signal of the first AFE module.

Thus, the frequency modulation module may be used to: and controlling the frequency of the SRS according to the frequency of the modulated BS.

The control of the SRS frequency can be realized through the frequency modulation module, repeated adjustment of the SRS frequency is not needed, and the switching time of the SRS is reduced.

It should be noted that the frequency modulation modules in the RFIC provided in the first aspect of the present application may also be plural. In the case where the RFIC includes a plurality of frequency modulation modules, the plurality of frequency modulation modules may be electrically connected to the plurality of AFE modules in one-to-one correspondence. Of course, the number of frequency modulation modules can be smaller than that of the AFE modules, and one frequency modulation module can be electrically connected with one, two or more AFE modules, so that the control of the frequencies of SRS output by different AFE modules can be realized. The number of the frequency modulation modules is not limited.

In a second aspect, the present application provides an RFIC that may include a plurality of DFE modules, a plurality of AFE modules, a switching module, and a plurality of radio frequency channels.

Wherein a first DFE module of the plurality of DFE modules (i.e., any DFE module of the plurality of DFE modules) can be electrically coupled to the BBIC. That is, the input of the first DFE module may be electrically connected to the output of the BBIC.

Optionally, the plurality of DFE modules are electrically connected to the plurality of AFE modules in a one-to-one correspondence, each AFE module of the plurality of AFE modules is electrically connected to a switching module, and the switching module is electrically connected to each radio frequency channel of the plurality of radio frequency channels.

Thus, the output of the first DEF module may be electrically connected to the input of the first AFE module and the output of the second DEF module may be electrically connected to the input of the second AFE module. The output end of each of the first AFE module and the second AFE module can be electrically connected with the input end of the switching module, and the output end of the switching module is electrically connected with the first radio frequency channel and also can be electrically connected with the second radio frequency channel.

Further, the first DFE module may be configured to: and modulating the BS transmitted by the BBIC, and transmitting the modulated BS to the first AFE module.

The first AFE module is to: the modulated BS is converted into SRS. Wherein the SRS may include second destination information. The second destination information is used to indicate a transmission destination of the SRS.

The switching module may be configured to: and when the transmission destination of the SRS is the second radio frequency channel, switching the SRS from the first radio frequency channel to the second radio frequency channel according to the second destination information, and outputting the SRS through the second radio frequency channel.

It can be appreciated that, before the switching module switches the SRS, the transmission destination of the SRS may be the first radio frequency channel and output through the first radio frequency channel. After the switching module switches the SRS, the SRS may be output through the second radio frequency channel.

It is conceivable that the switching module is further configured to switch the SRS from the second radio frequency channel to the first radio frequency channel according to the second destination information in a case where the switching module switches the SRS and the transmission destination of the SRS is the first radio frequency channel. That is, the switching module may switch the SRS between different radio frequency channels.

It can be appreciated that before the switching module switches the SRS, the SRS may be output through the second radio frequency channel. After the switching module switches the SRS, the SRS may be output through the first radio frequency channel.

Thus, similar to the first DFE module, the second DFE module may be configured to: and modulating the BS transmitted by the BBIC, and transmitting the modulated BS to a second AFE module.

Similar to the first AFE module, the second AFE module can be configured to: the modulated BS is converted into SRS.

Further, the switching module may be configured to: and when the transmission destination of the SRS is the first radio frequency channel, switching the SRS from the second radio frequency channel to the first radio frequency channel according to the second destination information, and outputting the SRS through the first radio frequency channel.

The RFIC provided in the second aspect of the present application may implement switching of the SRS from the first radio frequency channel to the second radio frequency channel through the switching module, that is, implementing soft switching of the SRS between different radio frequency channels through the switching module.

In one possible implementation, the switching module may include a first control unit, a first switch, a second switch, a third switch, and a fourth switch. That is, the switching module may include a first control unit and four switching switches. The four switches may be electrically connected to the first control unit, respectively.

The first end of each of the first change-over switch and the second change-over switch can be electrically connected with the first AFE module, the second end of the first change-over switch can be electrically connected with the first radio frequency channel, and the second end of the second change-over switch can be electrically connected with the second radio frequency channel. That is, a first end of the first switch may be electrically connected to the output of the first AFE module, and a second end of the first switch may be electrically connected to the first radio frequency channel. The first end of the second switch may also be electrically connected to the output of the first AFE module, and the second end of the second switch may be electrically connected to the second radio frequency channel.

Similarly, a first end of each of the third and fourth switches may be electrically connected to the second AFE module, a second end of the third switch may be electrically connected to the second radio frequency channel, and a second end of the fourth switch may be electrically connected to the first radio frequency channel. That is, a first end of the third transfer switch may be electrically connected to the output of the second AFE module, and a second end of the third transfer switch may be electrically connected to the second radio frequency channel. The first end of the fourth transfer switch may also be electrically connected to the output of the second AFE module, and the second end of the fourth transfer switch may be electrically connected to the first radio frequency channel.

The first control unit is used for: and controlling the first change-over switch, the second change-over switch, the third change-over switch and the fourth change-over switch according to the second destination information. That is, the first control unit may control the on/off of the four switches, so as to output the SRS signal through the first radio frequency channel or the second radio frequency channel.

For example, in the case where the transmission destination of the SRS is the first radio frequency channel and the SRS is from the first AFE module, the first control unit may control the first switch to be turned off and control the second switch, the third switch, and the fourth switch to be turned off respectively. The first switch may then transmit SRS from the first AFE module to the first radio frequency channel.

Also for example, in a case where the transmission destination of the SRS is the second radio frequency channel and the SRS is from the first AFE module, the first control unit may control the second switch to be closed, and control the first switch, the third switch, and the fourth switch to be opened respectively. The second switch may then transmit SRS from the first AFE module to the second radio frequency channel.

For another example, in a case where the transmission destination of the SRS is the first radio frequency channel and the SRS is from the second AFE module, the first control unit may control the fourth switch to be closed, and control the first switch, the second switch, and the third switch to be opened respectively. The fourth switch may then transmit SRS from the second AFE module to the first radio frequency channel.

For another example, in the case where the transmission destination of the SRS is the second radio frequency channel and the SRS is from the second AFE module, the first control unit may control the third switch to be closed, and control the first switch, the second switch, and the fourth switch to be opened respectively. The third switch may then transmit SRS from the second AFE module to the second radio frequency channel.

The control of the four switches in the switching module is realized through the first control unit, and meanwhile, the output of the SRS signal through the first radio frequency channel or the second radio frequency channel can be realized through the four switches, namely, the output of the SRS in any radio frequency channel in a plurality of radio frequency channels is realized.

In one possible implementation, the plurality of DFE modules may include a third DFE module in addition to the first DFE module and the second DFE module. The plurality of AFE modules may include a third AFE module in addition to the first AFE module and the second AFE module. The plurality of radio frequency channels may include a third radio frequency channel in addition to the first radio frequency channel and the second radio frequency channel.

The third DFE module may be electrically connected to the third AFE module, and the third AFE module may be electrically connected to the third radio frequency channel through the switching module.

Further, the switching module may further include a fifth switch, a sixth switch, a seventh switch, an eighth switch, and a ninth switch.

The first end of the fifth change-over switch can be electrically connected with the first AFE module, the first end of the sixth change-over switch can be electrically connected with the second AFE module, and the second ends of the fifth change-over switch and the sixth change-over switch can be respectively electrically connected with the third radio frequency channel. That is, a first end of the fifth transfer switch may be electrically connected to the output of the first AFE module, and a second end of the fifth transfer switch may be electrically connected to the third radio frequency channel. The first end of the sixth transfer switch may be electrically connected to the output of the second AFE module, and the second end of the sixth transfer switch may also be electrically connected to the third radio frequency channel.

The first ends of the seventh, eighth and ninth switches may be electrically connected to the third AFE module, respectively, the second end of the seventh switch may be electrically connected to the third radio frequency channel, the second end of the eighth switch may be electrically connected to the first radio frequency channel, and the second end of the ninth switch may be electrically connected to the second radio frequency channel. That is, a first end of the seventh transfer switch may be electrically connected to the output of the third AFE module, and a second end of the seventh transfer switch may be electrically connected to the third radio frequency channel. The first end of the eighth transfer switch may be electrically connected to the output of the third AFE module, and the second end of the eighth transfer switch may be electrically connected to the first radio frequency channel. The first end of the ninth transfer switch may be electrically connected to the output of the third AFE module, and the second end of the ninth transfer switch may be electrically connected to the second radio frequency channel.

Thus, the first control unit may also be adapted to: and controlling the fifth change-over switch, the sixth change-over switch, the seventh change-over switch, the eighth change-over switch and the ninth change-over switch according to the second destination information. That is, the first control unit may control the on and off of the first, second, third and fourth switches, and may control the on and off of the fifth, sixth, seventh, eighth and ninth switches, so as to output the SRS signal through any one of the first, second and third radio frequency channels.

For example, in the case where the transmission destination of the SRS is the first radio frequency channel and the SRS is from the first AFE module, the first control unit may control the first switch to be turned off, and control the second switch, the third switch, the fourth switch, the fifth switch, the sixth switch, the seventh switch, the eighth switch, and the ninth switch (i.e., the switches other than the first switch in the switching module) to be turned off, respectively. The first switch may then transmit SRS from the first AFE module to the first radio frequency channel.

Also for example, in a case where the transmission destination of the SRS is the first radio frequency channel and the SRS is from the second AFE module, the first control unit may control the fourth switch to be closed, and control the first switch, the second switch, the third switch, the fifth switch, the sixth switch, the seventh switch, the eighth switch, and the ninth switch (i.e., the switches other than the fourth switch in the switching module) to be opened, respectively. The fourth switch may then transmit SRS from the second AFE module to the first radio frequency channel.

Also for example, in a case where the transmission destination of the SRS is the first radio frequency channel and the SRS is from the third AFE module, the first control unit may control the eighth switch to be closed, and control the first switch, the second switch, the third switch, the fourth switch, the fifth switch, the sixth switch, the seventh switch, and the ninth switch (i.e., the switches other than the eighth switch in the switch module) to be opened, respectively. Then, the eighth switch may transmit SRS from the third AFE module to the first radio frequency channel.

Also for example, in a case where the transmission destination of the SRS is the second radio frequency channel and the SRS is from the first AFE module, the first control unit may control the second switch to be closed, and control the first switch, the third switch, the fourth switch, the fifth switch, the sixth switch, the seventh switch, the eighth switch, and the ninth switch (i.e., the switches other than the second switch in the switch module) to be opened, respectively. The second switch may then transmit SRS from the first AFE module to the second radio frequency channel.

Also for example, in a case where the transmission destination of the SRS is the second radio frequency channel and the SRS is from the second AFE module, the first control unit may control the third switch to be closed, and control the first switch, the second switch, the fourth switch, the fifth switch, the sixth switch, the seventh switch, the eighth switch, and the ninth switch (i.e., the switches other than the third switch in the switch module) to be opened, respectively. The third switch may then transmit SRS from the second AFE module to the second radio frequency channel.

Also for example, in a case where the transmission destination of the SRS is the second radio frequency channel and the SRS is from the third AFE module, the first control unit may control the ninth switch to be closed, and control the first switch, the second switch, the third switch, the fourth switch, the fifth switch, the sixth switch, the seventh switch, and the eighth switch (i.e., the switches other than the ninth switch in the switch module) to be opened, respectively. The ninth switch may then transmit SRS from the third AFE module to the second radio frequency channel.

Also for example, in a case where the transmission destination of the SRS is the third radio frequency channel and the SRS is from the first AFE module, the first control unit may control the fifth switch to be turned on, and control the first switch, the second switch, the third switch, the fourth switch, the sixth switch, the seventh switch, the eighth switch, and the ninth switch (i.e., the switches other than the fifth switch in the switching module) to be turned off, respectively. The fifth switch may then transmit SRS from the first AFE module to the third radio frequency channel.

Also for example, in a case where the transmission destination of the SRS is the third radio frequency channel and the SRS is from the second AFE module, the first control unit may control the sixth switch to be closed, and control the first switch, the second switch, the third switch, the fourth switch, the fifth switch, the seventh switch, the eighth switch, and the ninth switch (i.e., the switches other than the sixth switch in the switching module) to be opened, respectively. The sixth switch may then transmit SRS from the second AFE module to the third radio frequency channel.

In the case where the RFIC includes a plurality of frequency modulation modules, the plurality of frequency modulation modules may be electrically connected to the plurality of AFE modules in one-to-one correspondence. Of course, the number of frequency modulation modules may be smaller than the number of AFE modules, and one frequency modulation module may be electrically connected to two or more AFE modules, so as to control the frequency of SRS output by different AFE modules. The number of the frequency modulation modules is not limited.

The second amplification module may be configured to: and amplifying the SRS, and transmitting the amplified SRS to a second transmitting module.

The radio frequency transmitting device provided in the fourth aspect of the present application avoids setting a switch between the amplifying module and the transmitting module, and switches the SRS transmitted by the RFIC from the first amplifying module to the second amplifying module through the FEM, that is, soft switching of the SRS between different transmitting modules is achieved through the FEM. And the area of the radio frequency transmitting device is reduced, and the cost and the transmitting power consumption of the radio frequency transmitting device are reduced.

In one possible implementation manner, the radio frequency integrated circuit in the fourth aspect of the present application may include a plurality of DFE modules, a plurality of AFE modules, and a plurality of radio frequency channels.

Wherein a first DFE module of the plurality of DFE modules (i.e. any DFE module of the plurality of DFE modules) may be electrically connected to the baseband integrated circuit BBIC. That is, the input of the first DFE module may be electrically connected to the output of the BBIC.

Alternatively, the plurality of DFE modules may be electrically connected to the plurality of AFE modules in one-to-one correspondence, the plurality of AFE modules may be electrically connected to the plurality of radio frequency channels, and the plurality of radio frequency channels may be electrically connected to the FEM, respectively.

As introduced above, the plurality of DFE modules may include a first DEF module and a second DEF module. The plurality of AFE modules may include a first AFE module and a second AFE module. The plurality of radio frequency channels may include a first radio frequency channel and a second radio frequency channel.

The output of the first DEF module may then be electrically connected to the input of the first AFE module, the output of the first AFE module being electrically connected to the input of the FEM through the first radio frequency channel. The output of the second DEF module may be electrically connected to the input of the second AFE module, and the output of the second AFE module may be electrically connected to the input of the FEM through a second radio frequency channel.

The first AFE module may be to: and converting the modulated BS into SRS, and outputting the SRS to the FEM through a first radio frequency channel.

The RFIC may also include a frequency modulation module, for example. The frequency modulation module may be electrically connected to each of the plurality of AFE modules. For example, the frequency modulation module may be electrically connected to the first AFE module and may also be electrically connected to the second AFE module.

The RFIC can control the frequency of the SRS through the frequency modulation module, the frequency of the SRS does not need to be repeatedly regulated, and the switching time of the SRS is reduced.

Note that, the number of the frequency modulation modules in the RFIC may be plural. In the case where the RFIC includes a plurality of frequency modulation modules, the plurality of frequency modulation modules may be electrically connected to the plurality of AFE modules in one-to-one correspondence. Of course, the number of frequency modulation modules may be smaller than the number of AFE modules, and one frequency modulation module may be electrically connected to two or more AFE modules, so as to control the frequency of SRS output by different AFE modules. The number of the frequency modulation modules is not limited.

In another possible implementation manner, the FEM may include a third control unit and an eleventh switch.

Wherein the third control unit may be electrically connected to the eleventh changeover switch. The first radio frequency channel, the second radio frequency channel, the first amplification module and the second amplification module may be electrically connected to the eleventh switch, respectively.

Thus, the third control unit may be configured to: and controlling an eleventh change-over switch to change over the SRS output by the first radio frequency channel from the first amplifying module to the second amplifying module. That is, the third control unit may control the on and off of the eleventh switch to realize the switching of the SRS from the first amplification module to the second amplification module.

The SRS from the first radio frequency channel is switched from the first amplifying module to the second amplifying module through the FEM, namely, soft switching of the SRS between different sending modules is realized through the FEM.

Illustratively, the eleventh change-over switch may be a double pole double throw switch (double pole double throw, DPDT). The eleventh transfer switch may include a first input terminal, a second input terminal, a first output terminal, and a second output terminal. The first input end can be electrically connected with the first radio frequency channel, the second input end can be electrically connected with the second radio frequency channel, the first output end can be electrically connected with the first amplifying module, and the second output end can be electrically connected with the second amplifying module.

Thus, the eleventh transfer switch may transmit the SRS from the first radio frequency channel to the second amplification module through the first input terminal and the second output terminal, or may transmit the SRS from the second radio frequency channel to the first amplification module through the second input terminal and the first output terminal.

Of course, the eleventh switch may be of other types, which is not limited in this application.

It should be noted that, the second transmitting module and the related description of the radio frequency front end unit in the second transmitting module in the fourth aspect of the present application may refer to the above, and the description is omitted herein.

It should be understood that, in the second aspect to the fourth aspect of the present application, the technical solutions of the first aspect of the present application are consistent, and beneficial effects obtained by each aspect and corresponding possible embodiments are similar, and are not repeated.

Detailed Description

The technical solutions in the present application will be described below with reference to the accompanying drawings.

The terms "first," "second," and the like in the description and in the claims and drawings are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion, such as a series of steps or elements. The method, system, article, or apparatus is not necessarily limited to those explicitly listed but may include other steps or elements not explicitly listed or inherent to such process, method, article, or apparatus.

It should be understood that in this application, "at least one" means one or more, and "a plurality" means two or more. "and/or" for describing the association relationship of the association object, the representation may have three relationships, for example, "a and/or B" may represent: only a, only B and both a and B are present, wherein a, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b or c may represent: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", wherein a, b, c may be single or plural.

To overcome the above-described deficiencies, embodiments of the present application provide a radio frequency integrated circuit (radio frequency integrated circuit, RFIC) as shown in fig. 1. The RFIC may include a switching module 11, two (i.e., a plurality of, fig. 1, for example) digital front end (digital front end, DFE) modules (may simply be referred to as DFE modules) 12, two (i.e., a plurality of, fig. 1, for example) Analog Front End (AFE) modules (may simply be referred to as AFE modules) 13, and two (i.e., a plurality, fig. 1, for example, two) radio frequency channels (TX) 14.

Wherein the two DEF modules 12 may include a DFE module 1 (i.e., a first DFE module) and a DFE module 2 (i.e., a second DFE module). It is understood that DFE module 1 and DFE module 2 may be different DFE modules. The two AFE modules 13 may include an AFE module 1 (i.e., a first AFE module) and an AFE module 2 (i.e., a second AFE module). It is understood that AFE module 1 and AFE module 2 may be different AFE modules. The two TX14 may include TX1 (i.e., a first radio frequency channel) and TX2 (i.e., a second radio frequency channel). It is to be appreciated that TX1 and TX2 may be different TX.

Alternatively, the output of the BBIC may be electrically connected to the input of the switching module 11. The output of the switching module 11 may be electrically connected to the input of the DFE module 1, and the output of the switching module 11 may also be electrically connected to the input of the DFE module 2. That is, the output terminal of the switching module 11 may be electrically connected with the input terminal of each DFE module.

The two DFE modules 12 may be electrically connected 2 in one-to-one correspondence with the two AFE modules 13, and the two AFE modules 13 may be electrically connected in one-to-one correspondence with the two TX 14. Further, an output of the DFE module 1 may be electrically connected to an input of the AFE module 1, and an output of the AFE module 1 may be electrically connected to TX 1. Similarly, the output of the DFE module 2 may be electrically connected to the input of the AFE module 2, and the output of the AFE module 2 may be electrically connected to the TX 2.

Alternatively, the switching module 11 may be configured to: BS receiving BBIC transmissions. Wherein the BS may include destination information a (i.e., first destination information). The destination information a may be used to indicate a transmission destination of the BS. In case that the transmission destination of the BS is TX2, the switching module 11 may also be used to switch the BS from the DEF module 1 to the DEF module 2 according to the destination information a.

It will be appreciated that the BS may be input to the DFE module 1 before the BS is handed over by the handover module 11. It can be seen that the switching module 11 acts as a pass-through, transmitting the BS directly to the DFE module 1. After the handover module performs handover to the BS, the BS may then input the DFE module 2. It can be seen that the switching module 11 switches the BS from the DEF module 1 to the DEF module 2, the switching module 11 playing a switching role.

The DFE module 2 can then be used to: the BS from the handover module 11 is modulated to obtain a modulated BS. The DFE module 2 may also be used to transmit the modulated BS to the AFE module 2.

The AFE module 2 can be used to: the modulated BS transmitted by the DFE module 2 is converted into SRS and output through TX 2. As can be seen, TX2 functions to output SRS.

It is conceivable that the switching module 11 may also be used to switch the BS from the DEF module 2 to the DEF module 1 according to the destination information a in case the switching module 11 switches the BS and the transmission destination of the BS is TX1, that is, the switching module 11 may switch the BS between different DFE modules.

It will be appreciated that the BS may be input to the DFE module 2 before the BS is handed over by the handover module 11. It can be seen that the switching module 11 acts as a pass-through, transmitting the BS directly to the DFE module 2. After the handover module performs handover to the BS, the BS may then input the DFE module 1.

Thus, similar to DFE module 2, DFE module 1 can be used to: the BS from the handover module 11 is modulated to obtain a modulated BS. The DFE module 1 may also be used to transmit the modulated BS to the AFE module 1.

Similar to AFE module 2, AFE module 1 can be used to: the modulated BS transmitted by the DFE module 1 is converted into SRS and output through TX 1. As can be seen, TX1 functions to output SRS.

The RFIC provided in this embodiment of the present application may implement the switching from DEF module 1 to DEF module 2 by using the switching module 11, that is, implement the soft switching between different DFE modules by using the BS, and further implement the switching from TX1 to TX2 by using the SRS.

Further, the switching module 11 may include a baseband interface (baseband interface, BIF). As shown IN fig. 2, the BIF may include an input terminal IN, an output terminal OUT1 (i.e., a first output terminal), and an output terminal OUT2 (i.e., a second output terminal). Wherein IN may be electrically connected to the output of BBIC, OUT1 may be electrically connected to the input of DEF module 1, and OUT2 may be electrically connected to the input of DEF module 2. Thus, the IN may receive BSs of BBIC transmissions. OUT1 may transmit BS to DEF module 1.OUT2 may transmit the BS to DEF module 2.

It will be appreciated that IN and OUT1 may constitute the primary channel of the BIF and IN and OUT2 may constitute the secondary channel of the BIF. The BS may transmit to the DFE module 1 through a primary channel, and then output the SRS through TX 1. In the case that TX2 needs to output SRS, BS may transmit to DFE module 2 through an auxiliary channel, and further output SRS through TX2, that is, the SRS is switched between TX1 and TX 2.

It is conceivable that TX1 and TX2 do not output SRS at the same time. That is, when TX2 outputs SRS, TX1 does not output SRS. Conversely, when TX1 outputs SRS, TX2 does not output SRS.

With continued reference to fig. 2, the rfic may include a frequency modulation module 15 (e.g., a phase locked loop, etc.). The frequency modulation module 15 may be electrically connected to each of the plurality of AFE modules 13. For example, the frequency modulation module 15 may be electrically connected to the AFE module 1, and may also be electrically connected to the AFE module 2.

It will be appreciated that the modulated BS may be an input signal of the AFE module 1, and the SRS may be an output signal of the AFE module 1.

Thus, the frequency modulation module 15 may be configured to: and controlling the frequency of the SRS according to the frequency of the modulated BS.

According to the embodiment of the application, the control of the SRS frequency can be realized through the frequency modulation module 15, repeated adjustment of the SRS frequency is not needed, and the switching time of the SRS is reduced.

Note that, the number of the frequency modulation modules 15 in the RFIC shown in fig. 2 may be plural. In the case where the RFIC includes a plurality of frequency modulation modules, the plurality of frequency modulation modules may be electrically connected to the plurality of AFE modules in one-to-one correspondence. Of course, the number of frequency modulation modules 15 may be smaller than the number of AFE modules, and one frequency modulation module may be electrically connected to one, two or more AFE modules, so as to realize control of the frequency of SRS output by different AFE modules. The number of the frequency modulation modules is not limited in the embodiment of the application.

In another embodiment of the present application, as shown in fig. 3, the RFIC may include a switching module 11, three (i.e., a plurality, two for example in fig. 3) DFE modules 12, three (i.e., a plurality, two for example in fig. 3) AFE modules 13, and three (i.e., a plurality, two for example in fig. 3) TX14.

Wherein the three DEF modules 12 may include a DFE module 1, a DFE module 2, and a DFE module 3 (i.e., a third DFE module). It is understood that DFE module 1, DFE module 2, and DFE module 3 may be different DFE modules. The three AFE modules 13 may include an AFE module 1, an AFE module 2, and an AFE module 3 (i.e., a third AFE module). It is understood that AFE module 1, AFE module 2, and AFE module 3 may be different AFE modules. The three TX14 may include TX1, TX2, and TX3 (i.e., a third radio frequency channel). It is to be appreciated that TX1, TX2, and TX3 may be different TX.

Optionally, the output of the BBIC in fig. 3 may also be electrically connected to the input of the switching module 11. The output end of the switching module 11 may be electrically connected to the input end of the DFE module 1, the output end of the switching module 11 may be electrically connected to the input end of the DFE module 2, and the output end of the switching module 11 may be electrically connected to the input end of the DFE module 3. That is, the output terminal of the switching module 11 may be electrically connected with the input terminal of each DFE module.

The three DFE modules 12 may be electrically connected 2 in a one-to-one correspondence with the three AFE modules 13, and the three AFE modules 13 may be electrically connected in a one-to-one correspondence with the three TX 14. Further, an output of the DFE module 1 may be electrically connected to an input of the AFE module 1, and an output of the AFE module 1 may be electrically connected to TX 1. Similarly, the output of the DFE module 2 may be electrically connected to the input of the AFE module 2, and the output of the AFE module 2 may be electrically connected to the TX 2. An output of the DFE module 3 may be electrically connected to an input of the AFE module 3, and an output of the AFE module 3 may be electrically connected to TX 3.

Alternatively, the switching module 11 may be configured to: BS receiving BBIC transmissions. Wherein the BS may include destination information a. In case that the transmission destination of the BS is TX3, the switching module 11 may also be used to switch the BS from the DEF module 1 to the DEF module 3 according to the destination information a.

It will be appreciated that the BS may be input to the DFE module 1 before the BS is handed over by the handover module 11. It can be seen that the switching module 11 acts as a pass-through, transmitting the BS directly to the DFE module 1. After the handover module performs handover to the BS, the BS may then input the DFE module 3. It can be seen that the switching module 11 switches the BS from the DEF module 1 to the DEF module 3, the switching module 11 playing a switching role.

The DFE module 3 can then be used to: the BS from the handover module 11 is modulated to obtain a modulated BS. The DFE module 3 may also be used to transmit the modulated BS to the AFE module 3.

The AFE module 3 may be configured to: the modulated BS transmitted by the DFE module 3 is converted into SRS and output through TX 3. As can be seen, TX3 functions to output SRS.

Of course, referring to the description above, the switching module 11 may also switch the BS from the DEF module 2 to the DEF module 3, switch the BS from the DEF module 3 to the DEF module 1, or switch the BS from the DEF module 3 to the DEF module 2, or the like. The embodiments of the present application will not be described in detail.

Further, as shown in fig. 4, the switching module 11 may include a BIF. The BIF IN fig. 4 may include an input terminal IN, an output terminal OUT1, an output terminal OUT2, and an output terminal OUT3. Wherein IN may be electrically connected to the output of BBIC, OUT1 may be electrically connected to the input of DEF module 1, OUT2 may be electrically connected to the input of DEF module 2, and OUT3 may be electrically connected to the input of DEF module 3.

Thus, the IN may receive BSs of BBIC transmissions. OUT1 may transmit BS to DEF module 1.OUT2 may transmit the BS to DEF module 2.OUT3 may transmit the BS to DEF module 3.

It will be appreciated that IN and OUT1 may constitute the primary channel of the BIF, IN and OUT2 may constitute the secondary channel 1 of the BIF, and IN and OUT3 may constitute the secondary channel 2 of the BIF. The BS may transmit to the DFE module 1 through a primary channel, and then output the SRS through TX 1. In case that TX2 needs to output SRS, the BS may transmit to DFE module 2 through auxiliary channel 1, and further output SRS through TX 2. Of course, in case that TX3 needs to output SRS, BS may transmit to DFE module 3 through supplemental channel 2. It can be seen that the switching of SRS between TX1, TX2 and TX3 is achieved by the switching module 11.

With continued reference to fig. 4, the rfic may include a frequency modulation module 15. The frequency modulation module 15 may be electrically connected to each of the plurality of AFE modules 13. For example, the frequency modulation module 15 may be electrically connected to the AFE module 1, the AFE module 2, or the AFE module 3.

It should be noted that, the relevant description of the frequency modulation module may refer to the above, and the embodiments of the present application are not repeated.

In the embodiments of the present application, the RFIC is described by taking only two DFE modules, two AFE modules, and two TX as examples, and the RFIC is described by taking only three DFE modules, three AFE modules, and three TX as examples in fig. 3 and 4. Of course, the RFIUC provided in the embodiment of the present application may further include four, five, or more DFE modules, AFE modules, and TX, that is, the number of DFE modules, AFE modules, and TX is not limited in the embodiment of the present application. The switching module 11 may also implement soft switching between different DFE modules by the BS, which is not described in detail in this embodiment of the present application.

The embodiment of the application also provides an RFIC, as shown in fig. 5. As with the RFIC shown in fig. 1 and 2, the RFIC shown in fig. 5 may also include a switching module 11, two DFE modules 12, two AFE modules 13, and two TX14. It should be noted that the RFIC shown in fig. 5 in the embodiment of the present application may also include a BIF (not shown in fig. 5), where an input terminal of the BIF is electrically connected to an output terminal of the BBIC, and an output terminal of the BIF is connected to an input terminal of the DFE module 1. The BIF may transmit the BS to the DFE module 1. It can be seen that the BIF in fig. 5 acts as a pass-through.

Unlike the RFICs shown in fig. 1 and 2, the output of the BBIC may be electrically connected to the input of either of the two DFE modules 12. That is, the output terminal of the BBIC may be electrically connected to the input terminal of the DFE module 1 or electrically connected to the input terminal of the DFE module 2, which is not limited in the embodiment of the present application. In the embodiment of the present application, the output terminal of the BBIC is electrically connected to the input terminal of the DFE module 1.

Referring to fig. 5, an output terminal of the dfe module 1 may be electrically connected to an input terminal of the AFE module 1, and an output terminal of the AFE module 1 may be electrically connected to TX 1. Similarly, the output of the DFE module 2 may be electrically connected to the input of the AFE module 2, and the output of the AFE module 2 may be electrically connected to the TX 2.

Further, the DFE module 1 may be configured to: the BS transmitted by BBIC is modulated, and the modulated BS is transmitted to the AFE module 1.

The AFE module 1 is for: the modulated BS is converted into SRS. Wherein the SRS may include destination information B (i.e., second destination information). The destination information B may be used to indicate a transmission destination of the SRS.

The switching module 11 may be configured to: in the case where the transmission destination of the SRS is TX2, the SRS may be switched from TX1 to TX2 according to the destination information and output through TX 2. It can be seen that the switching module 11 plays a role in switching, and TX2 plays a role in outputting SRS.

The RFIC provided in fig. 5 of the embodiment of the present application may implement the switching of SRS from TX1 to TX through the switching module 11, that is, implement the soft switching of SRS between different TX through the switching module 11.

Further, with continued reference to fig. 5, the switching module 11 may include a control unit a (i.e., a first control unit, not shown in fig. 3) and four switches. The four switches may include a switch S1 (i.e., a first switch), a switch S2 (i.e., a second switch), a switch S3 (i.e., a third switch), and a switch S4 (i.e., a fourth switch). The control unit a may be electrically connected to the four switches, and control the four switches according to the destination information B. That is, the control unit a may control the on and off of the four switches, thereby realizing the output of the SRS signal through TX1 or TX 2.

Wherein, the first end of each of the switch S1 and the switch S2 may be electrically connected to the AFE module 1, the second end of the switch S1 may be electrically connected to the TX1, and the second end of the switch S2 may be electrically connected to the TX 2. That is, a first terminal of the switch S1 may be electrically connected to the output terminal of the AFE module 1, and a second terminal of the switch S1 may be electrically connected to the TX 1. The first end of the switch S2 may also be electrically connected to the output of the AFE module 1, and the second end of the switch S2 may be electrically connected to TX 2.

Similarly, a first end of each of the switch S3 and the switch S4 may be electrically connected to the AFE module 2, a second end of the switch S3 may be electrically connected to the TX2, and a second end of the switch S4 may be electrically connected to the TX1. That is, a first terminal of the switch S3 may be electrically connected to the output terminal of the AFE module 2, and a second terminal of the switch S3 may be electrically connected to the TX2. The first end of the switch S4 may also be electrically connected to the output of the AFE module 2, and the second end of the switch S4 may be electrically connected to TX1.

According to the above electrical connection relationship and the control of the four switches by the control unit a, soft handoff of SRS from the AFE module between different TX can be achieved. The following can be distinguished:

case one: the transmission destination of the SRS is TX1 and the SRS is from AFE module 1

The control unit a may control the switch S1 to be closed, and control the switch S2, the switch S3, and the switch S4 to be opened respectively. The switch S1 may then transmit SRS from the AFE module 1 to TX1. It can be seen that the switching module 11 acts as a pass-through.

And a second case: the transmission destination of the SRS is TX2 and the SRS comes from AFE module 1

The control unit a may control the switch S2 to be closed, and control the switch S1, the switch S3, and the switch S4 to be opened respectively. The switch S2 may then transmit SRS from the AFE module 1 to TX2. It can be seen that the switching module 11 performs a switching function.

And a third case: the transmission destination of the SRS is TX1 and the SRS comes from AFE module 2

The control unit a may control the switch S4 to be closed, and control the switch S1, the switch S2, and the switch S3 to be opened respectively. The switch S4 may then transmit SRS from the AFE module 2 to TX1. It can be seen that the switching module 11 performs a switching function.

Case four: the transmission destination of the SRS is TX2 and the SRS comes from AFE module 2

The control unit a may control the switch S3 to be closed, and control the switch S1, the switch S2, and the switch S4 to be opened respectively. The switch S3 may then transmit SRS from the AFE module 2 to TX2.

In the above cases, the transmission paths of SRS are as shown in table 1:

TABLE 1

BBIC	DFE module 1	AFE1 Module 1	S1	TX1
					BBIC	DFE module 2	AFE1 Module 2	S4	TX1
BBIC	DFE module 1	AFE1 Module 1	S2	TX2
					BBIC	DFE module 2	AFE1 Module 2	S3	TX2

The control unit A controls four switches in the switching module 11, and meanwhile, the SRS signals can be output through the TX1 or the TX2 through the four switches, namely, the SRS is output in any one of a plurality of TX.

Further, the RFIC shown in fig. 5 may also include a frequency modulation module 15. The frequency modulation module 15 may be electrically connected to the AFE module 1 and may also be electrically connected to the AFE module 2.

The plurality of AFE modules 13 may include an AFE module 3 in addition to the AFE module 1 and the AFE module 2. The plurality of TX14 may include TX3 in addition to TX1 and TX 2.

Wherein the DFE module 3 may be electrically connected with the AFE module 3, and the AFE module 3 may be electrically connected with the TX3 through the switching module 11.

Similar to fig. 5, the RFIC shown in fig. 6 of the present embodiment may also include a BIF (not shown in fig. 6), an input of which is electrically connected to an output of the BBIC, and an output of which may be connected to an input of the DFE module 1. The BIF may transmit the BS to the DFE module 1. It can be seen that the BIF in fig. 6 acts as a pass-through.

Further, the switch module 11 may further include a switch S5 (i.e., a fifth switch), a switch S6 (i.e., a sixth switch), a switch S7 (i.e., a seventh switch), a switch S8 (i.e., an eighth switch), and a switch S9 (i.e., a ninth switch).

With continued reference to fig. 6, a first end of the switch S5 may be electrically connected to the AFE module 1, a first end of the switch S6 may be electrically connected to the AFE module 2, and second ends of the switch S5 and the switch S6 may be electrically connected to TX3, respectively. That is, a first terminal of the switch S5 may be electrically connected to the output terminal of the AFE module 1, and a second terminal of the switch S5 may be electrically connected to the TX3. A first end of the switch S6 may be electrically connected to the output of the AFE module 2, and a second end of the switch S6 may also be electrically connected to TX3.

The first ends of the switch S7, the switch S8 and the switch S9 may be electrically connected to the AFE module 3, the second end of the switch S7 may be electrically connected to the TX3, the second end of the switch S8 may be electrically connected to the TX1, and the second end of the switch S9 may be electrically connected to the TX 2. That is, a first terminal of the switch S7 may be electrically connected to the output terminal of the AFE module 3, and a second terminal of the switch S7 may be electrically connected to the TX 3. A first end of the switch S8 may be electrically connected to the output of the AFE module 3, and a second end of the switch S8 may be electrically connected to TX 1.

Thus, the control unit a may also be used to: the switch S5, the switch S6, the switch S7, the switch S8, and the switch S9 are controlled according to the destination information B. That is, the control unit a may control the on and off of the switches S5, S6, S7, S8 and S9 in addition to the switches S1, S2, S3 and S4, thereby realizing the SRS signal output through any one of TX1, TX2 and TX 3.

According to the above electrical connection relationship and the control of the nine switches by the control unit a, soft handoff of SRS from the AFE module between different TX can be achieved. The following can be distinguished:

The control unit a may control the switch S1 to be turned on, and control the switch S2, the switch S3, the switch S4, the switch S5, the switch S6, the switch S7, the switch S8, and the switch S9 (i.e., the switches other than the switch S1 in the switch module 11) to be turned off, respectively. The switch S1 may then transmit SRS from the AFE module 1 to TX1. It can be seen that the switching module 11 can transmit SRS from the AFE module 1 to TX1, which plays a pass-through role.

And a second case: the transmission destination of the SRS is TX1 and the SRS comes from AFE module 2

The switch S3 may then transmit SRS from the AFE module 2 to TX2. It can be seen that the switching module 11 can transmit SRS from the AFE module 2 to the TX2, which plays a pass-through role.

Case six: the transmission destination of the SRS is TX2 and the SRS comes from AFE module 3

The control unit a may control the switch S9 to be turned on, and control the switches S1, S2, S3, S4, S5, S6, S7, and S8 (i.e., the switches other than the switch S9 in the switch module 11) to be turned off, respectively. The switch S9 may then transmit SRS from the AFE module 3 to TX2. It can be seen that the switching module 11 can switch SRS from TX3 to TX2, which plays a role in switching.

Case seven: the transmission destination of the SRS is TX3 and the SRS comes from AFE module 1

The control unit a may control the switch S5 to be turned on, and control the switches S1, S2, S3, S4, S6, S7, S8, and S9 (i.e., the switches other than the switch S5 in the switch module 11) to be turned off, respectively. The switch S5 may then transmit SRS from the AFE module 1 to TX3. It can be seen that the switching module 11 can switch SRS from TX1 to TX3, which plays a role in switching.

Case eight: the transmission destination of the SRS is TX3 and the SRS comes from AFE module 2

The switch S6 may then transmit SRS from the AFE module 2 to TX3. It can be seen that the switching module 11 can switch SRS from TX2 to TX3, which plays a role in switching.

Case nine: the transmission destination of the SRS is TX3 and the SRS comes from AFE module 3

The number of amplifying modules and the number of transmitting modules may be the same as the number of TX in the RFIC. Thus, the embodiment of the present application will be described by taking the example in which the radio frequency transmission apparatus 10 includes two amplifying modules 1 and two transmitting modules 2.

The BBIC may include a plurality of baseband channels (BBA) and radio frequency interfaces (radio freqency interface, RIF), among others. The plurality of BBAs may include BBA1 and BBA2.BBA1 and BBA2 may be electrically connected to the RIF, respectively.

Alternatively, BBA1 and BBA2 may be used to output BS, respectively, and transmitted to RIF. The RIF can then process the BS output by BBA1 to obtain a BS that includes destination information A.

Further, the RIF may be electrically connected to the switching module 11 (as an input terminal of the RFIC), the plurality of TX14 may be electrically connected to the two amplifying modules 1 in one-to-one correspondence, and the two amplifying modules 1 may be electrically connected to the two transmitting modules 2 in one-to-one correspondence.

Similarly, the transmitting module 22 may include a radio frequency front end unit 220, an antenna unit 221, and a wire unit 222.

The antenna unit 221, the antenna unit 222, and the amplifying module 12 may be electrically connected to the rf front-end unit 220, respectively.

Antenna element 221 or antenna element 222 may be used to: and sending the filtered SRS. That is, the filtered SRS may be transmitted through the antenna unit 221 or the antenna unit 222.

It should be noted that the structures of other sending modules may be the same as those of the sending module 21 and the sending module 22, and the description of the other sending modules may refer to the description above, which is not repeated in the embodiment of the present application.

The filtering of the SRS is realized through the radio frequency front-end unit, and the sending of the SRS is realized through any antenna unit, so that not only can the interference signals in the SRS be effectively removed and the quality of the SRS be improved, but also the sending power consumption of a sending module can be reduced, and further the sending power consumption of the radio frequency sending device 10 is reduced.

The rf front-end unit 220 is described below as an example.

The filtering unit may be configured to: the amplified SRS from the amplifying module 12 is filtered to obtain a filtered SRS.

Thus, the control unit B may be configured to: the switch S10 is controlled to transmit the filtered SRS to the antenna unit 221 or the antenna unit 222. That is, the control unit B may control the switch S10 to be closed, and further transmit the filtered SRS through the antenna unit 221 or the antenna unit 222.

Illustratively, the switch S10 may be a single pole double throw switch (single pole double throw, SPDT).

Wherein IN may be electrically connected to the filter unit, OUT1 may be electrically connected to the antenna unit 221, and OUT2 may be electrically connected to the antenna unit 222.

Then, the switch S10 may transmit the filtered SRS to the antenna unit 221 through IN and OUT1, or may transmit the filtered SRS to the antenna unit 222 through IN and OUT2.

In some embodiments of the present application, the BBIC in fig. 8 can include a RIF and at least one BBA. In this embodiment, taking BBIC including BBA1 as an example, BBA1 may be electrically connected to the RIF respectively.

Alternatively, BBA1 may output the BS and transmit to the RIF. The RIF can then process the BS output by BBA1 to obtain a BS that includes destination information A. The radio frequency transmission apparatus 10 shown in fig. 8 may transmit SRS in the following cases:

case one: the transmission module 21 transmits the amplified SRS

The RIF transmits the BS including the destination information a to the DEF module 1 of the RFIC1 through the BIF 1. The DFE module 1 of the RFIC1 modulates the BS to obtain a modulated BS. The AFE module 1 of the RFIC1 converts the modulated BS into SRS and transmits to the amplifying module 11 through TX1 of the RFIC 1. The amplification module 11 amplifies the SRS and transmits the amplified SRS to the transmission module 21.

It should be noted that, in the RIF in fig. 8 of the present embodiment, the BS is switched from the BIF1 to the BIF2, so that not only the transmission of the amplified SRS through the transmission module 21 is switched to the transmission through the transmission module 23 or the transmission module 24, but also the transmission of the amplified SRS through the transmission module 22 is switched to the transmission through the transmission module 23 or the transmission module 24.

Of course, if taking the BBA4 output BS as an example, the RIF in fig. 8 of the embodiment of the present application may also implement the BS handoff from the BIF2 to the BIF1. Thus, not only switching of transmission of the amplified SRS by the transmission module 23 to transmission by the transmission module 21 or the transmission module 22 but also switching of transmission of the amplified SRS by the transmission module 24 to transmission by the transmission module 21 or the transmission module 22 can be achieved.

Taking the BBA1 output BS as an example, the radio frequency transmitting apparatus 10 shown in fig. 10 may transmit SRS in the following cases:

case one: the transmission module 21 transmits the amplified SRS

The RIF transmits the BS including the destination information a to the DEF module 1 of the RFIC 1. The DFE module 1 of the RFIC1 modulates the BS to obtain a modulated BS. The AFE module 1 of the RFIC1 converts the modulated BS into SRS and transmits to the amplifying module 11 through the switch S1 of the RFIC1 and TX1 of the RFIC 1. The amplification module 11 amplifies the SRS and transmits the amplified SRS to the transmission module 21. The transmission module 21 transmits the amplified SRS (which may be represented by SRS 21).

And a second case: the transmission module 22 transmits the amplified SRS

The RIF transmits the BS including the destination information a to the DEF module 1 of the RFIC 1. The DFE module 1 of the RFIC1 modulates the BS to obtain a modulated BS. The AFE module 1 of the RFIC1 converts the modulated BS into SRS and transmits to the amplifying module 12 through the switches S2 and TX2 of the RFIC 1. The amplification module 12 amplifies the SRS and transmits the amplified SRS to the transmission module 22. The transmission module 22 transmits the amplified SRS (which may be represented by SRS 22).

And a third case: the transmission module 23 transmits the amplified SRS

The RIF switches the BS including the destination information a from BIF1 to BIF2.BIF2 transmits the BS of destination information a to DFE module 1 of RFIC 2. The DFE module 1 of the RFIC2 modulates the BS to obtain a modulated BS. The AFE module 1 of the RFIC2 converts the modulated BS into SRS and transmits to the amplifying module 13 through S1 and TX1 of the RFIC 2. The amplification module 13 amplifies the SRS and transmits the amplified SRS to the transmission module 23. The transmission module 23 transmits the amplified SRS (which may be represented by SRS 23).

Case four: the transmission module 24 transmits the amplified SRS

The RIF switches the BS including the destination information a from BIF1 to BIF2.BIF2 switches the BS of destination information a from DFE module 1 of RFIC2 to DFE module 2 of RFIC 2. The DFE module 2 of the RFIC2 modulates the BS to obtain a modulated BS. The AFE module 2 of the RFIC2 converts the modulated BS into SRS and transmits to the amplifying module 14 through S2 and TX2 of the RFIC 2. The amplification module 14 amplifies the SRS and transmits the amplified SRS to the transmission module 24. The transmission module 24 transmits the amplified SRS (which may be represented by SRS 24).

In the above cases, the transmission paths of SRS are as shown in table 6:

Of course, if BS is output by other BBAs in the BIIC, except the BBAs, the RIF in fig. 10 of the embodiment of the present application may also implement the handover of BS from BIF2 to BIF1. Similarly, in combination with the four switches in the RFIC1, not only can the transmission of the amplified SRS be switched to the transmission by the transmission module 23 or the transmission module 21 or 22, but also the transmission of the amplified SRS by the transmission module 24 can be switched to the transmission by the transmission module 21 or 22.

Alternatively, the RIF processes the BS output by the BBA2 and transmits the BS including the destination information a to the DFE module 2 of the RFIC 1. Alternatively, the RIF processes the BS output by BBA3 and transmits the BS including the destination information a to DFE module 1 of RFIC 2. Alternatively, the RIF processes the BS output by the BBA4 and transmits the BS including the destination information a to the DFE module 2 of the RFIC 2. It can be seen that the RIF only plays a pass-through role.

Optionally, the switching module 11 of the RFIC1 may further comprise a switch S12 and a switch S13. The switching module 11 of the RFIC1 may also comprise a switch S14 and a switch S15.
