Embodiments of the present invention will be further described below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a terminal capable of supporting an FDD system according to an embodiment of the present invention.
As shown in fig. 1, the terminal includes a signal transceiver antenna 100, a signal transmitting module 200, a signal receiving module 300, a duplexer 400 and a signal processing module 800, wherein the duplexer 400 includes an uplink signal terminal 410, a downlink signal terminal 420 and a signal common terminal 430, the uplink signal terminal 410 is connected to the signal transmitting module 200, the downlink signal terminal 420 is connected to the signal receiving module 300, the signal common terminal 430 is connected to the signal transceiver antenna 100, and the signal processing module 800 is connected to the signal transmitting module 200 and the signal receiving module 300, respectively.
In an embodiment, when the terminal position changes or the channel environment changes and the signal quality of the terminal is detected to be reduced by the base station, the base station may send the SRS request information to the terminal, and in addition, the base station may also send the SRS request information to the terminal at regular time, so, in a case that the signal processing module 800 receives the SRS request information from the base station through the signal receiving module 300, the signal processing module 800 may generate corresponding SRS information according to the SRS request information, and send the SRS information to the base station through the signal transmitting module 200, the duplexer 400 and the signal receiving antenna 100, so that the base station can perform corresponding channel quality estimation according to the SRS information, thereby correspondingly adjusting the transmitting antenna of the base station, so that the maximum gain direction of the transmitting antenna of the base station can face the terminal, and the quality of the signal of the base station received by the terminal is improved.
In an embodiment, the signal transceiver antenna is an antenna with a larger operating frequency band capable of supporting uplink signal and downlink signal transmission, and the operating frequency of the signal transceiver antenna includes the uplink signal transmission frequency and the downlink signal transmission frequency, so that the terminal can transmit the uplink signal and receive the downlink signal through the signal transceiver antenna. In the terminal structure of fig. 1, when the signal transmitting/receiving antenna 100 receives SRS request information from a base station, the signal transmitting/receiving antenna 100 transmits the SRS request information to the signal processing module 800 through the duplexer 400 and the signal receiving module 300, and therefore, the signal processing module 800 may generate SRS information according to the SRS request information and transmit the SRS information to the base station through the signal transmitting module 200, the duplexer 400 and the signal transmitting/receiving antenna 100. Accordingly, for a terminal supporting the FDD system, when SRS request information from a base station is received through the signal receiving module 300, SRS information can be generated according to the SRS request information and transmitted to the base station by using a transmission link configured by the transmitting module 200, the duplexer 400, and the signal transmitting/receiving antenna 100, so that transmission of the SRS information in the FDD system can be achieved.
In an embodiment, the terminal may be a terminal supporting at least one of a 3G network system, a 4G network system, a 5G network system, and a subsequent higher network system, which is not particularly limited in this embodiment. It should be noted that, the structure of the terminal described in this embodiment is for more clearly describing the technical solution of the embodiment of the present invention, and does not constitute a limitation on the technical solution provided by the embodiment of the present invention, and those skilled in the art can know that, with evolution of the network system and occurrence of a new application scenario, the technical solution provided by the embodiment of the present invention is applicable to similar technical problems.
In addition, referring to fig. 2, in an embodiment, the terminal further includes a first switch 500, the signal transmitting module 200 includes a first transmitting end 210 and a second transmitting end 220, the first transmitting end 210 is connected to the uplink signal end 410, and the first switch 500 is connected to the second transmitting end 220, the signal receiving module 300, the downlink signal end 420 and the signal processing module 800, respectively.
In an embodiment, after the signal processing module 800 receives the SRS request information from the base station to generate the SRS information, the signal processing module 800 may control the first switch 500 to connect the second transmitting end 220 and the downlink signal end 420, and modulate the SRS information to the downlink signal transmission frequency to obtain the first SRS signal, and then transmit the first SRS signal by using the signal transmitting module 200, so that the first SRS signal may be transmitted to the duplexer 400 through the second transmitting end 220 and the downlink signal end 420, and be transmitted to the base station through the duplexer 400 and the signal transceiver antenna 100.
In an embodiment, by controlling the first switch 500 to connect the second transmitting terminal 220 and the downlink signal terminal 420 to each other, the signal transmitting module 200, the duplexer 400 and the signal receiving and transmitting antenna 100 can form a transmission link for transmitting signals modulated to the downlink signal transmission frequency, so that when the signal processing module 800 modulates the SRS information to the downlink signal transmission frequency to obtain the first SRS signal, the SRS information can be transmitted to the base station by using the transmission link. Because the frequency of the first SRS signal is consistent with the transmission frequency of the downlink signal, after the base station receives the first SRS signal, the channel quality of the downlink channel of the terminal can be accurately judged, so that the transmitting antenna of the base station can be more accurately regulated, the maximum gain direction of the transmitting antenna of the base station can be more accurately oriented to the terminal, and the quality of the base station signal received by the terminal is improved.
Note that, although the transmission module 200 is commonly used to transmit the first SRS signal and the uplink signal by using different transmission links, the uplink signal transmitted by the terminal to the base station is temporarily interrupted in the process of transmitting the first SRS signal to the base station, and in order to reduce the influence on the transmission of the uplink signal caused by the transmission of the first SRS signal, the first SRS signal and the uplink signal may be transmitted at intervals, or the first SRS signal and the uplink signal may be allocated to different time slots, and different signals may be correspondingly transmitted according to different time slots, which is not limited in this embodiment.
In addition, in an embodiment, referring to fig. 3, the signal transmitting module 200 further includes a first transmitting link 230 and a second switch 240, the second switch 240 is connected to the signal processing module 800, the first transmitting link 230, the first transmitting terminal 210 and the second transmitting terminal 220, respectively, and the first transmitting link 230 is connected to the signal processing module 800.
In an embodiment, after the signal processing module 800 receives the SRS request information from the base station to generate the SRS information and modulates the SRS information to the downlink signal transmission frequency to obtain the first SRS signal, in order to make the first SRS signal and the uplink signal be distinguished and transmitted through different transmission links, the signal transmitting module 200 may be provided with the second switch 240, and the second switch 240 is respectively connected to the signal processing module 800, the first transmission link 230, the first transmission end 210 and the second transmission end 220, so when the first SRS signal needs to be transmitted to the base station, the signal processing module 800 may first control the second switch 240 to make the first transmission link 230 alternately connect the first transmission end 210 and the second transmission end 220, and utilize the first transmission link 230 to alternately transmit the uplink signal and the first SRS signal, so that the first SRS signal is transmitted to the duplexer 400 through the second transmission end 220 and the downlink signal end 420, and the uplink signal is transmitted through the first transmission end 210 and the uplink signal end 410, thereby realizing the isolation of the first SRS signal and the uplink signal 400.
In an embodiment, the signal processing module 800 synchronously performs control over the second switch 240 and alternate transmission of the uplink signal and the first SRS signal by using the first transmission link 230, so that not only can transmission isolation of the first SRS signal and the uplink signal be accurately achieved, but also signal transmission failure caused by untimely or erroneous switching of the transmission links can be avoided. It should be noted that, the signal processing module 800 performs the control of the second switch 240 and the operation of alternately transmitting the uplink signal and the first SRS signal by using the first transmission link 230 synchronously, which may be performed at fixed time intervals or according to signal transmission time slots, which is not limited in this embodiment. For example, when the signal processing module 800 performs control of the second switch 240 according to the signal transmission slot synchronization and alternately transmits the uplink signal and the first SRS signal using the first transmission link 230, the first transmission link 230 and the first transmission terminal 210 may be connected in a slot length for transmitting the uplink signal, where only the uplink signal is transmitted in the slot length, and the first transmission link 230 and the second transmission terminal 220 may be connected in a slot length for transmitting the first SRS signal, where only the first SRS signal is transmitted in the slot length.
In addition, referring to fig. 4, in an embodiment, the signal transmitting module 200 further includes a first transmitting link 230 and a second transmitting link 250, where the first transmitting link 230 is connected to the signal processing module 800 and the first transmitting terminal 210, and the second transmitting link 250 is connected to the signal processing module 800 and the second transmitting terminal 220, respectively.
It should be noted that the embodiment shown in fig. 4 and the embodiment shown in fig. 3 are mutually parallel.
In an embodiment, since the signal transmitting module 200 includes the first transmitting link 230 and the second transmitting link 250, and the first transmitting link 230 is connected to the signal processing module 800 and the first transmitting end 210, and the second transmitting link 250 is connected to the signal processing module 800 and the second transmitting end 220, when the signal processing module 800 receives the SRS request information from the base station to generate the SRS information, the signal processing module 800 can modulate the SRS information to the downlink signal transmission frequency to obtain the first SRS signal, and since the frequency of the first SRS signal is different from the frequency of the uplink signal, the first SRS signal can be transmitted by using the second transmitting link 250, and the uplink signal can be transmitted by using the first transmitting link 230. Since the first transmission link 230 and the second transmission link 250 are isolated from each other, the first SRS signal and the uplink signal may not affect each other, so that the first SRS signal and the uplink signal may be transmitted simultaneously, not only may the terminal not affect the transmission of the uplink signal to the base station, but also the terminal may be ensured to transmit the first SRS signal to the base station, so that the base station may accurately determine the channel quality of the downlink channel of the terminal according to the first SRS signal, thereby more accurately adjusting the transmission antenna of the base station, and enabling the maximum gain direction of the transmission antenna of the base station to be more accurately oriented to the terminal, so as to improve the quality of the signal received by the terminal.
In an embodiment, the second transmission link may be a dedicated link for transmitting the first SRS signal, or may be a general link capable of being configured for transmitting the first SRS signal, which may be appropriately selected according to the actual application, and this embodiment is not limited specifically.
In addition, unlike the embodiments shown in fig. 2,3 and 4, in an embodiment, the signal processing module 800 may modulate the SRS information to the uplink signal transmission frequency to obtain the second SRS signal, so the signal transmitting module 200 may transmit the second SRS signal to the duplexer 400 through the uplink signal terminal 410, so that the second SRS signal can be transmitted to the base station through the duplexer 400 and the signal transceiver antenna 100. It should be noted that, in the process that the terminal transmits the second SRS signal to the base station through the transmitting module 200, the duplexer 400 and the signal transmitting/receiving antenna 100, that is, in the process that the terminal transmits the second SRS signal to the base station through the uplink signal transmission link formed by the transmitting module 200, the duplexer 400 and the signal transmitting/receiving antenna 100, the uplink signal transmitted by the terminal to the base station may be temporarily interrupted, so that in order to reduce the influence on the transmission of the uplink signal caused by the transmission of the second SRS signal, the second SRS signal and the uplink signal may be transmitted at intervals, or the second SRS signal and the uplink signal may be allocated to different time slots, and different signals may be correspondingly transmitted according to different time slots, which is not limited in this embodiment.
In addition, referring to fig. 5, in an embodiment, the terminal further includes a signal receiving antenna 600 and a third switch 700, and the third switch 700 is connected to the signal transmitting module 200, the signal receiving module 300, the signal receiving antenna 600 and the signal processing module 800, respectively.
In an embodiment, in the case that the terminal includes the signal transceiver antenna 100 and the signal receiver antenna 600, the signal processing module 800 may control the third switch 700 to connect the signal transmitter module 200 and the signal receiver antenna 600, modulate the SRS information to the downlink signal transmission frequency to obtain the third SRS signal, and then transmit the third SRS signal to the base station through the signal receiver antenna 600 by using the signal transmitter module 200.
In an embodiment, the number of signal receiving antennas 600 corresponds to the number of third switches 700, and the signal receiving antennas 600 and the third switches 700 are connected in one-to-one correspondence. The number of the receiving antennas 600 and the number of the third switches 700 may be one or two or more, and may be appropriately selected according to the actual application, which is not particularly limited in this embodiment.
In an embodiment, in the case that the terminal includes the signal transceiver antenna 100 and the signal receiver antenna 600, that is, in the case that the terminal includes a plurality of signal receiver antennas, when the terminal receives SRS request information from the base station, the terminal may transmit corresponding SRS information to the base station through the signal receiver antennas. Because the terminal utilizes the plurality of signal receiving antennas to send SRS information to the base station, the base station can perform more accurate channel quality estimation according to the received plurality of SRS information, so that the transmitting antenna of the base station can be adjusted more accurately, the maximum gain direction of the transmitting antenna of the base station can be oriented to the terminal more accurately, and the quality of the base station signal received by the terminal is improved.
It will be appreciated by those skilled in the art that the terminal structure to which the various embodiments described above relate is not limiting to the embodiments of the invention and may include more or fewer components than those shown in the various figures described above, or may be combined with certain components or a different arrangement of components.
Based on the terminal structure of the above embodiment, various embodiments of a sounding reference signal transmission method of a frequency division duplex system are presented below.
As shown in fig. 6, fig. 6 is a flowchart of a sounding reference signal transmission method of a frequency division duplex system according to an embodiment of the present invention, and the transmission method may be applied to a terminal supporting an FDD system according to the embodiment shown in fig. 1, and the transmission method includes, but is not limited to, the following steps:
Step S100, when SRS request information from a base station is received through a signal receiving module, SRS information is generated according to the SRS request information;
step S200, the SRS information is sent to the base station through the signal transmitting module, the duplexer and the signal transceiver antenna.
In an embodiment, when the position of the terminal changes or the channel environment changes and the base station detects that the signal quality of the terminal decreases, the base station may send SRS request information to the terminal, and in addition, the base station may also send the SRS request information to the terminal at regular time, so when the terminal receives the SRS request information from the base station through the signal receiving module, the terminal may generate corresponding SRS information according to the SRS request information, and send the SRS information to the base station through the signal transmitting module, the duplexer and the signal receiving antenna, so that the base station may perform corresponding channel quality estimation according to the SRS information, so that the transmitting antenna of the base station may be adjusted correspondingly, and the maximum gain direction of the transmitting antenna of the base station may face the terminal, so as to improve the quality of the signal of the base station received by the terminal.
In an embodiment, the signal transceiver antenna is an antenna with a larger operating frequency band capable of supporting uplink signal and downlink signal transmission, and the operating frequency of the signal transceiver antenna includes the uplink signal transmission frequency and the downlink signal transmission frequency, so that the terminal can transmit the uplink signal and receive the downlink signal through the signal transceiver antenna. Therefore, when the signal transceiving antenna receives the SRS request information from the base station, the terminal may receive the SRS request information through the duplexer and the signal receiving module, and then the terminal may generate SRS information according to the SRS request information and transmit the SRS information to the base station through the signal transmitting module, the duplexer and the signal transceiving antenna. Therefore, for the terminal supporting the FDD system, when the SRS request information from the base station is received through the signal receiving module, the SRS information can be generated according to the SRS request information, and the SRS information is sent to the base station by using the transmission link formed by the transmitting module, the duplexer and the signal receiving and transmitting antenna, so that the transmission of the SRS information in the FDD system can be realized.
In addition, in an embodiment, when the terminal further includes a first switch, and the signal transmitting module includes a first transmitting end and a second transmitting end, and the first transmitting end is connected to the upstream signal end, and the first switch is connected to the second transmitting end, the signal receiving module, and the downstream signal end, respectively, referring to fig. 7, step S200 may include, but is not limited to, the following steps:
Step S210, controlling the first switch to be communicated with the second transmitting terminal and the downlink signal terminal;
Step S220, modulating SRS information to a downlink signal transmission frequency to obtain a first SRS signal;
In step S230, the signal transmitting module is used to transmit the first SRS signal, so that the first SRS signal is transmitted to the duplexer through the second transmitting end and the downlink signal end, and is transmitted to the base station through the duplexer and the signal receiving and transmitting antenna.
In an embodiment, after the terminal receives the SRS request information from the base station to generate the SRS information, the terminal may control the first switch to communicate with the second transmitting end and the downlink signal end, and modulate the SRS information to the downlink signal transmission frequency to obtain the first SRS signal, and then transmit the first SRS signal by using the signal transmitting module, so that the first SRS signal may be transmitted to the duplexer through the second transmitting end and the downlink signal end, and be transmitted to the base station through the duplexer and the signal transceiver antenna.
In an embodiment, the second transmitting end and the downlink signal end are connected by controlling the first switch, so that the signal transmitting module, the duplexer and the signal receiving and transmitting antenna form a transmission link for transmitting the signal modulated to the downlink signal transmission frequency, and therefore, when the terminal modulates the SRS information to the downlink signal transmission frequency to obtain the first SRS signal, the SRS information can be sent to the base station by using the transmission link. Because the frequency of the first SRS signal is consistent with the transmission frequency of the downlink signal, after the base station receives the first SRS signal, the channel quality of the downlink channel of the terminal can be accurately judged, so that the transmitting antenna of the base station can be more accurately regulated, the maximum gain direction of the transmitting antenna of the base station can be more accurately oriented to the terminal, and the quality of the base station signal received by the terminal is improved.
Note that, although the first SRS signal and the uplink signal are transmitted using different transmission links, the transmission module is commonly used, so that the uplink signal transmitted by the terminal to the base station is temporarily interrupted in the process of transmitting the first SRS signal to the base station, and in order to reduce the influence on the transmission of the uplink signal caused by the transmission of the first SRS signal, the first SRS signal and the uplink signal may be transmitted at intervals, or the first SRS signal and the uplink signal may be allocated to different time slots, and different signals may be correspondingly transmitted according to different time slots, which is not limited in this embodiment.
In addition, in an embodiment, when the signal transmitting module further includes a first transmitting link and a second switch, and the second switch is connected to the first transmitting link, the first transmitting end and the second transmitting end, respectively, referring to fig. 8, the step S230 of transmitting the first SRS signal by using the signal transmitting module may include, but is not limited to, the following steps:
step S231, controlling a second change-over switch to enable the first transmission link to alternately communicate the first transmission end and the second transmission end;
step S232, the uplink signal and the first SRS signal are alternately transmitted by using the first transmitting link, where the first SRS signal is transmitted to the duplexer through the second transmitting end and the downlink signal end, and the uplink signal is transmitted to the duplexer through the first transmitting end and the uplink signal end.
In an embodiment, after the terminal receives the SRS request information from the base station to generate the SRS information and modulates the SRS information to the downlink signal transmission frequency to obtain the first SRS signal, in order to enable the first SRS signal and the uplink signal to be distinguished and transmitted through different transmission links, a second switch may be set in the signal transmission module, and the second switch is connected to the first transmission link, the first transmission end and the second transmission end respectively, so when the first SRS signal needs to be transmitted to the base station, the terminal may first control the second switch to enable the first transmission link to be alternately connected to the first transmission end and the second transmission end, and utilize the first transmission link to alternately transmit the uplink signal and the first SRS signal, so that the first SRS signal is transmitted to the duplexer through the second transmission end and the downlink signal end, and the uplink signal is transmitted to the duplexer through the first transmission end and the uplink signal end, thereby realizing transmission isolation of the first SRS signal and the uplink signal.
In an embodiment, the terminal synchronously performs control over the second switch and alternately transmits the uplink signal and the first SRS signal by using the first transmission link, so that transmission isolation of the first SRS signal and the uplink signal can be accurately realized, and signal transmission failure caused by untimely or erroneous switching of the transmission link can be avoided. It should be noted that, the terminal synchronously performs the control of the second switch and the operation of alternately transmitting the uplink signal and the first SRS signal by using the first transmission link, which may be performed at fixed time intervals or may be performed according to a signal transmission time slot, which is not limited in this embodiment. For example, when the control of the second switch and the alternate transmission of the uplink signal and the first SRS signal by the first transmission link are performed in synchronization with each other according to the signal transmission slot, the first transmission link and the first transmission end may be connected in the slot length in which the uplink signal is transmitted, in which case only the uplink signal is transmitted, and the first transmission link and the second transmission end may be connected in the slot length in which the first SRS signal is transmitted, in which case only the first SRS signal is transmitted.
In addition, in an embodiment, when the signal transmitting module further includes a first transmitting link and a second transmitting link, and the first transmitting link is connected to the first transmitting end and the second transmitting link is connected to the second transmitting end, referring to fig. 9, the step S230 of transmitting the first SRS signal by using the signal transmitting module may further include, but is not limited to, the following steps:
Step S233, a first SRS signal is transmitted by using a second transmitting link;
in step S234, the uplink signal is transmitted using the first transmission link.
It should be noted that the embodiment shown in fig. 9 and the embodiment shown in fig. 8 are mutually parallel.
In an embodiment, since the signal transmitting module includes a first transmitting link and a second transmitting link, and the first transmitting link is connected to the first transmitting end, and the second transmitting link is connected to the second transmitting end, after the terminal receives the SRS request information from the base station to generate the SRS information, the terminal may modulate the SRS information to a downlink signal transmission frequency to obtain the first SRS signal, and since the frequency of the first SRS signal is different from the frequency of the uplink signal, the first SRS signal may be transmitted by using the second transmitting link, and the uplink signal may be transmitted by using the first transmitting link. Because the first transmitting link and the second transmitting link are isolated from each other, the first SRS signal and the uplink signal cannot be mutually influenced, so that the first SRS signal and the uplink signal can be transmitted simultaneously, the terminal cannot be influenced to transmit the uplink signal to the base station, the terminal can be ensured to transmit the first SRS signal to the base station, the base station can accurately judge the channel quality of a downlink channel of the terminal according to the first SRS signal, the transmitting antenna of the base station can be accurately adjusted, and the maximum gain direction of the transmitting antenna of the base station can be accurately oriented to the terminal, so that the quality of the base station signal received by the terminal is improved.
In an embodiment, the second transmission link may be a dedicated link for transmitting the first SRS signal, or may be a general link capable of being configured for transmitting the first SRS signal, which may be appropriately selected according to the actual application, and this embodiment is not limited specifically.
In addition, unlike the embodiment shown in fig. 7, 8 and 9, in an embodiment, referring to fig. 10, step S200 may further include, but is not limited to, the following steps:
Step S240, modulating the SRS information to an uplink signal transmission frequency to obtain a second SRS signal;
step S250, the signal transmitting module is utilized to transmit the second SRS signal to the duplexer through the uplink signal end, so that the second SRS signal is transmitted to the base station through the duplexer and the signal transceiver antenna.
In an embodiment, the terminal may further modulate the SRS information to an uplink signal transmission frequency to obtain a second SRS signal, so the terminal may transmit the second SRS signal to the duplexer through the uplink signal end by using the signal transmitting module, so that the second SRS signal may be transmitted to the base station through the duplexer and the signal transceiver antenna. It should be noted that, in the process that the terminal sends the second SRS signal to the base station through the transmitting module, the duplexer and the signal transceiving antenna, that is, in the process that the terminal sends the second SRS signal to the base station through the uplink signal transmission link formed by the transmitting module, the duplexer and the signal transceiving antenna, the uplink signal sent by the terminal to the base station may be temporarily interrupted, so that in order to reduce the influence on the sending of the uplink signal caused by the sending of the second SRS signal, the second SRS signal and the uplink signal may be sent at intervals, or the second SRS signal and the uplink signal may be allocated to different time slots, and different signals may be correspondingly sent according to different time slots, which is not limited in this embodiment.
In addition, in an embodiment, when the terminal further includes a signal receiving antenna and a third switch, and the third switch is connected to the signal transmitting module, the signal receiving module and the signal receiving antenna, respectively, referring to fig. 11, the transmission method may further include, but is not limited to, the following steps:
step S300, a third change-over switch is controlled to be communicated with a signal transmitting module and a signal receiving antenna;
Step S400, modulating SRS information to a downlink signal transmission frequency to obtain a third SRS signal;
in step S500, the signal transmitting module is used to transmit the third SRS signal to the base station through the signal receiving antenna.
In an embodiment, when the terminal includes a signal transceiver antenna and a signal receiver antenna, the terminal may control the third switch to connect the signal transmitter module and the signal receiver antenna, modulate the SRS information to the downlink signal transmission frequency to obtain a third SRS signal, and then transmit the third SRS signal to the base station through the signal receiver antenna by using the signal transmitter module.
In an embodiment, the number of signal receiving antennas corresponds to the number of third switches, and the signal receiving antennas and the third switches are connected in one-to-one correspondence. The number of the receiving antennas and the number of the third switches may be one or two or more, and may be appropriately selected according to practical application, which is not particularly limited in this embodiment.
In an embodiment, in a case that the terminal includes a signal transceiver antenna and a signal receiver antenna, that is, in a case that the terminal includes a plurality of signal receiver antennas, when the terminal receives SRS request information from the base station, the terminal may transmit corresponding SRS information to the base station through the signal receiver antenna loops. Because the terminal utilizes the plurality of signal receiving antennas to send SRS information to the base station, the base station can perform more accurate channel quality estimation according to the received plurality of SRS information, so that the transmitting antenna of the base station can be adjusted more accurately, the maximum gain direction of the transmitting antenna of the base station can be oriented to the terminal more accurately, and the quality of the base station signal received by the terminal is improved.
