Those skilled in the art will appreciate that the configuration of the handset 100 shown in fig. 1 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components. The technical solution of the present invention is described below by taking a mobile terminal as an example, wherein the mobile terminal is not limited to be applied to a mobile phone, and can also be applied to a tablet computer and the like. The present invention will be described below with reference to specific examples, but the present invention is not limited to these specific examples.
In the embodiment of the present invention, the dual modes respectively refer to a Frequency Division Duplex (FDD) mode and a Time Division Duplex (TDD) mode. For FDD mode, it relies on frequency to distinguish uplink from downlink, i.e. transmission and reception use different radio frequency points for communication respectively, and time is continuous on unidirectional resources, as shown in fig. 2 (a). For TDD mode, which relies on different time slots of the same frequency carrier for reception and transmission, a guard time is allocated between uplink and downlink, which is discontinuous in time on unidirectional resources as shown in fig. 2 (b). In consideration of the shortage of frequency spectrum resources in the FDD mode, the TDD mode has rich frequency spectrum resources, and the frequency spectrum resources can be better distributed by adopting the TDD + FDD dual-mode combination, so that the frequency spectrum utilization rate, the data transmission peak rate of the terminal and the like are improved.
For a mobile terminal with Carrier Aggregation (CA) and/or multiple-input multiple-output (MIMO) functions, in order to improve the data transmission rate of the mobile terminal, the mobile terminal may use a TDD mode for uplink transmission while in an FDD mode under the condition that a CA combination or a MIMO combination is adopted, that is, a CA combination or a MIMO combination based on TDD and FDD fusion networking is implemented.
However, for the case that the terminal uses the TDD mode to perform uplink CA combining or MIMO combining while in the FDD mode, the throughput of the CA combining or MIMO combining may be low, which indicates that the current CA combining or MIMO combining is working abnormally. In view of this phenomenon, the inventors have found through extensive research and tests that, since different antenna switches may pass through a signal path, and a plurality of input and output ports (i.e., port ports) are usually provided in the same antenna switch, different internal paths may be formed between different input ports and different output ports. For different frequency bands in the combined frequency band, when the signal paths selected by the respective antenna switches pass through the same port of the same antenna switch, since the frequency band used in the TDD mode (hereinafter referred to as TDD frequency band) is on/off controlled according to the time sequence, the antenna switch may be turned off when the TDD frequency band is turned off, which may cause the frequency band used in the FDD mode (hereinafter referred to as FDD frequency band) to work abnormally, and thus cause the CA combination or MIMO combination to work abnormally.
Therefore, the embodiment of the present invention provides a method for configuring a signal path of a dual-mode terminal, which can effectively prevent signal paths corresponding to a TDD frequency band and an FDD frequency band from using the same port of the same antenna switch, thereby solving the problem that the FDD frequency band does not work due to a timing problem, ensuring a throughput rate of the terminal, and improving user experience. The signal path arrangement method is described in detail below with reference to specific embodiments.
Example 1
Referring to fig. 3, an embodiment of the present invention provides a signal path configuration method, which is applicable to a mobile terminal supporting dual-mode networking, such as a smart phone and a tablet. In this embodiment, the mobile terminal supports a fusion networking of an FDD mode and a TDD mode, and has CA and/or MIMO capabilities. Exemplarily, the signal path configuration method includes:
step S10, acquiring a combined frequency band, wherein the combined frequency band comprises an FDD frequency band and a TDD frequency band.
In order to effectively communicate with the network side device, the mobile terminal as the user equipment usually reports its CA and/or MIMO capability information to the network side, and the network side issues corresponding combined configuration information according to the reported capability information. Then, the mobile terminal will obtain the combined frequency band information from the received combined configuration information. It can be understood that the reported CA and/or MIMO capability information is corresponding according to the CA and/or MIMO functions supported by the mobile terminal. The combined configuration information includes available network resources allocated by the network side device for the user equipment.
In some embodiments, the combined configuration information may include, but is not limited to, information including combined frequency band information, frequency points of corresponding frequency bands, and received signal strength, wherein the combined frequency band information typically includes two or more frequency bands. Because the method of the embodiment of the invention aims at the problem of CA combination or MIMO combination configuration based on an FDD mode and a TDD mode, the combined frequency band information mainly comprises an FDD frequency band and a TDD frequency band.
Exemplarily, taking LTE (4G) system as an example, different frequency bands are divided into different modes for use, for example, currently, frequency bands supported by TDD mode include Band 33-Band 40, and frequency bands supported by FDD mode include Band 1-Band 14, Band 17-Band 25, etc. It can be understood that, with continuous research on frequency band resources, in the future, other frequency bands may be divided into the two modes, or may be divided and adjusted by the existing frequency bands, and the frequency bands referred to by the FDD frequency band and the TDD frequency band in this embodiment are not limited herein.
Step S20, performing signal path selection on each frequency band in the combined frequency band to obtain corresponding signal path configuration information.
For step S20, the mobile terminal selects signal paths for each received frequency band in the combined frequency band, and combines the selected signal paths to obtain the signal path configuration information. It can be understood that the signal path configuration information will be used as configuration information of a CA combination or a MIMO combination, and is used for combination registration and reporting to the network side.
In one embodiment, as shown in fig. 4, the step S20 may include:
step S210, querying a pre-stored signal path of each frequency band in the combined frequency band according to the obtained combined frequency band, and selecting at least two selected signal paths as corresponding frequency bands.
Generally, a mobile terminal may be provided with a data module that stores information such as a combination of all supported CA and/or MIMO bands, a signal path corresponding to each band, and a register value of a port of an ASM switch corresponding to each signal path.
For step S210, after the combined frequency band information is obtained, the mobile terminal queries the information pre-stored in the data module to obtain all signal paths of each frequency band in the combined frequency band. For the frequency band supporting the CA combination mode, two signal paths are selected for combination configuration; for the frequency band supporting the MIMO combination mode, at least four signal paths are selected for combination configuration.
For example, if the combined frequency Band includes Band1(FDD frequency Band) and Band41(TDD frequency Band) both supporting the CA combining method, two signal paths corresponding to Band1 and Band41 may be selected for signal path combination according to a preset rule. The preset rule may include, but is not limited to, selecting from all signal paths of the current frequency band from the front to the back according to a default sequence, or randomly selecting from the signal paths.
Step S220, generating the signal path configuration information of the combined frequency band according to the selected signal path of each frequency band.
Then, the selected corresponding signal paths of each frequency band are combined to obtain the signal path configuration information of the CA combination or the MIMO combination. It is understood that the combined signal path is configured by selecting a corresponding port from a driver file of a power amplifier (ASM PA) of a corresponding antenna switch. In addition, the signal path configuration information may include other related information for combination configuration besides the main information of the selected signal path of each frequency band in the combined frequency band, which is not described in detail herein.
Step S30, determine whether the signal paths respectively selected by the FDD frequency band and the TDD frequency band contain the same port information of the same antenna switch.
Exemplarily, by comparing whether each antenna switch in each selected signal path of the FDD frequency band is the same as any antenna switch in any selected signal path of the TDD frequency band one by one, if so, it is indicated that the two frequency bands will pass through the same antenna switch, at this time, it is further determined whether register values of port ports of the same antenna switch, through which the two frequency bands pass, are the same, if so, it is indicated that the phenomenon of passing through the same port of the same antenna switch exists in the FDD frequency band and the TDD frequency band, and at this time, step S40 is executed. Otherwise, if the selected signal paths of the two frequency bands do not pass through the same antenna switch or pass through the same antenna switch but do not pass through the same port, the step S40 is not executed.
Still taking the above Band1(FDD Band) and Band41(TDD Band) supporting CA combination as examples, if the signal paths selected by the Band1 are path0 and path1, and the signal paths selected by the Band41 are path330 and path331, the information of these four signal paths is as follows:
Band1path0：
XSW9xx 6: register value 0x1ASM9xx6 (switch 1): port1 register values 0x2
path1：
XSW9 xxx: register value 0x2ASM9xxx (switch 2): port2 register values 0x2
Band41path330：
XSW9xx 6: register value 0x2ASM9xx6 (switch 1): port1 register values 0x2
path331：
XSW9 xxx: register value 0x3ASM9xx (switch 3): port3 register values 0x2
As can be seen from the above signal paths, Band1path0 and Band41path330 pass through the same port1 (i.e. switch 1) of the same antenna switch 9xx6, and if the switch 1 is controlled by both frequency bands, the FDD frequency Band will not operate normally. It is understood that the XSW9xx6 and ASM9xx6 are used to indicate that the hardware module 9xx6 corresponds to the same antenna switch, and the hardware module 9xx6 includes two sub-modules, one is a switch ASM for distinguishing different frequency bands (i.e., ASM9xx6) and the other is an antenna switch XSW for selecting different antennas (i.e., XSW9xx 6).
Step S40, when the same port information exists, deleting the same port information in the signal path of the FDD frequency band from the signal path configuration information, and writing the register value of the same port in the antenna switch driver file of the antenna switch into the signal path of the FDD frequency band.
In order to avoid the occurrence of the same port through which the FDD frequency band and the TDD frequency band simultaneously control the same antenna switch, exemplarily, the port information deletion operation may be performed on the selected signal path of the FDD frequency band in the signal path configuration information, that is, the register value of the port is deleted from the selected signal path of the FDD frequency band, so that the subsequent FDD frequency band does not pass through the port through when the selected signal path is used.
It can be understood that, since the configuration flow of the CA combination or the MIMO combination is to configure a driver file of a Power Amplifier (PA) of an antenna switch, and then select a corresponding port (i.e., a port) in the driver file when configuring a signal path (signal path) of the combination, that is, select a corresponding port of a corresponding antenna switch from an ASMPA driver file for configuring the signal path of the combination, the information deleted at this time is register value information of a switch ASM of the antenna switch, which is used for entering from the power amplifier PA and distinguishing different frequency bands.
Meanwhile, the register value of the port is deleted in the selected signal path of the FDD frequency band, but the FDD frequency band still needs to pass through the antenna switch in the hardware path, so that the FDD frequency band still needs to be written into the drive file configuration of the antenna switch through the register value corresponding to the port, and the hardware path of the FDD frequency band is ensured to be through.
In some embodiments, the register value may be written in a driver file of the antenna switch XSW of the antenna switch. This is because the same physical device antenna switch includes a driver file for ASM PA and a driver file for XSW, and the signal path configuration operation can be performed on the same antenna switch through the two driver files.
Exemplarily, for writing the register value of the same port in the antenna switching driver file of the antenna switch into the signal path of the FDD frequency band in step S40, the method includes:
and in an XSW driving file of the antenna switch, performing OR operation on the register value of the same port and an original register value stored correspondingly to the signal path of the FDD frequency band, and then updating the original register value.
Still taking the above Band1 and Band41 as examples, the register value of the same port1 of the same antenna switch 9xx6 used in the two frequency bands is 0x02, and the original register value corresponding to the path0 of the Band1 stored in the XSW driving file in the antenna switch is 0x01, so that 0x03 (i.e. 0x01|0x02) is obtained by or operation, at this time, the register value of the path0 used for representing the FDD frequency Band in the XSW driving file is updated from 0x01 to 0x03, and the other signal path information is not changed, that is:
Band1path0：
XSW9xx 6: register value 0x3
It can be understood that, by deleting the same port used by the FDD frequency band, since the switch ASM for distinguishing the frequency bands and the antenna changeover switch XSW are substantially the same physical device, the normal operation of the hardware path can be ensured by writing the register value of the switch ASM into the FDD frequency band in the drive file of the XSW.
Furthermore, in some embodiments, as shown in fig. 5, the signal path configuration method further includes:
step S50, reporting the updated signal path configuration information of the combined frequency band to the network side, so as to serve as the CA combination or MIMO combination registered by the dual-mode terminal.
Exemplarily, after updating the signal path configuration information of the combined frequency band, it may be further determined whether the CA combination or the MIMO combination can be normally transmitted. For example, if the data amount received by the FDD frequency band and the TDD frequency band in the preset time is not lower than the preset data amount, it indicates that the registration is successful, and reports the registration to the network side. And if the frequency band is lower than the preset frequency band, judging that the registration fails.
It should be understood that, in the step S40, if there is no port using the same antenna switch, the mobile terminal does not perform the step S40, and usually performs registration failure determination on the signal path configuration information obtained in the step S20, determines that the registration is successful, and reports a corresponding signaling to the network side as a registered CA combination or MIMO combination.
