In order to increase the data transmission rate of a mobile terminal such as a mobile phone, a Carrier Aggregation (CA) technology and a multiple-Input and multiple-Output (MIMO) technology are two major current technologies.

The MIMO technology can significantly increase spectral efficiency and data transmission rate by transmitting a plurality of data streams using a plurality of transmit/receive antennas.
For a mobile terminal with CA and MIMO capabilities, when selecting a signal path (signal path) of a corresponding frequency band in a combination of CA and MIMO, the conventional scheme is mainly to perform CA combination or MIMO combination according to an automatic selection of a signal path arranged in front. However, there may be physical collision among the multiple signal paths selected in this way, which may result in abnormal operation of the set of acquired CA or MIMO combinations, e.g., low throughput, etc. Of course, if the configuration information of the signal path is added manually, it will take a lot of time and effort to perform manual investigation, and the work efficiency is low.

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.
Different mobile terminals may include different carrier aggregation (hereinafter CA) and multiple-input multiple-output (hereinafter MIMO) capabilities. In order to effectively communicate with the network side device, the mobile terminal as the user equipment usually reports its CA and MIMO capability information to the network device, and the network device issues corresponding combined configuration information according to the reported capability information. The combined configuration information includes available network resources, such as combined frequency band information, allocated by the network device to the user equipment. Then, the user equipment selects and combines signal paths of corresponding frequency bands according to the combined frequency band information obtained from the combined configuration information to obtain a group of CA combinations or MIMO combinations as the information transmission combination. If the data transmission can be successfully carried out through the group combination, the successful registration is indicated, and the mobile terminal reports a corresponding signaling to the network equipment.
It is to be understood that the above-mentioned CA combination (i.e., carrier aggregation combination) refers to a combination of signal paths of frequency bands used for CA communication; MIMO combining (i.e., multiple-input multiple-output combining) refers to a combination of signal paths based on frequency bands of MIMO communication.
Example 1
Referring to fig. 2, the present invention provides a signal path self-adapting method, which can be applied to a mobile terminal, such as a mobile phone, a tablet computer, etc., wherein the mobile terminal supports CA and MIMO capabilities, and can improve information transmission efficiency by registering a CA combination or a MIMO combination.
The signal path self-adaptation method is explained in detail below, as shown in fig. 2.
Step S10, after receiving the combined configuration information issued by the network side, obtaining the combined frequency band from the combined configuration information, and querying a pre-stored signal path corresponding to each frequency band in the combined frequency band.
Exemplarily, when information transmission combination configuration is required, the mobile terminal receives combination configuration information issued from the network side through an air interface (NR), and reads combination frequency band information in the combination configuration information. The combined frequency band information generally includes two or more frequency bands. In addition, the combination configuration information may further include other information such as a frequency point of a corresponding frequency band and a received signal strength.
In this embodiment, the mobile terminal stores information such as all CA and MIMO band combinations supported by the mobile terminal, signal paths (signal paths) corresponding to the respective bands, and path register values of corresponding switches on the respective signal paths in advance. The switch is an antenna switch, and the same antenna switch can comprise a plurality of input ends and a plurality of output ends, namely a plurality of corresponding connecting paths. The antenna switch is characterized in that a corresponding register value is arranged between each input end and each output end to distinguish different connection paths in the antenna switch, so the registers are called path registers, and the corresponding values are path register values.
For the step S10, after the combined frequency band information is obtained, the mobile terminal queries and reads all signal paths of the corresponding frequency band and the path register values of all switches on the signal paths according to the combined frequency band, for example, the signal paths may be stored in a designated list or a designated database, so as to perform query and call subsequently.
Step S20, selecting at least two signal paths from the signal paths of each frequency band that do not conflict with other frequency bands in the combined frequency band according to a preset selection rule.
In this embodiment, the combined frequency band includes two or more frequency bands, and for each frequency band, at least two signal paths are selected according to a preventive selection rule. For a certain frequency band, the number of selected signal paths can be determined according to the supported combination mode. For example, for a frequency band supporting the CA combination mode, two signal paths are selected; at least four signal paths can be selected for the frequency band supporting the MIMO combination mode.
As for the preset selection rule, as shown in fig. 3, the preset selection rule includes:
step S201, determining a transceiver port of each frequency band in the combined frequency band according to a port mapping rule of a radio frequency circuit in the mobile terminal, wherein different transceiver ports correspond to different signal paths.
Radio frequency chips used in mobile terminals usually have corresponding port mapping (i.e., port mapping rules), and when the chips are used to design radio frequency circuits, the port mapping rules need to be followed to ensure that no collision occurs between transceiver ports during radio frequency signal transceiving. It is understood that the port mapping rule depends on the specific type of rf chip used by the mobile terminal, and the transceiver port of each frequency band can be determined by the port mapping rule.
In this embodiment, the determination of a signal path of a frequency band mainly depends on devices such as a transceiver port, a switch, and an antenna that pass through. Wherein, a signal path may pass through a plurality of weather gates; in addition, a plurality of input terminals and a plurality of output terminals may be provided in the same switch, and a connection path may be formed between each input terminal and each output terminal. After the transceiver ports of each frequency band are determined by the port mapping rule, the corresponding signal paths are further determined according to the anti-collision rule.
Step S202, at least two signal paths are selected for the corresponding frequency band from the signal paths corresponding to the transceiver ports of each determined frequency band according to the anti-collision rule.
Considering that the combined frequency band in the CA combination or the MIMO combination currently supported by the mobile terminal mainly includes two frequency bands, this embodiment will mainly take the two frequency bands as an example to describe the signal path self-adapting method. Of course, more frequency bands can be combined, and the principle is similar.
As a first possible implementation manner, the combined frequency band includes a first frequency band and a second frequency band both supporting CA combination, and for the step S202, as shown in fig. 4, the selecting of the signal path based on the anti-collision rule includes:
in the sub-step S211, for the first frequency band, two paths are respectively selected from the signal paths corresponding to the transceiver port of the first frequency band as the main set path and the diversity path of the first frequency band.
In the sub-step S212, for the second frequency band, two paths are respectively selected from the signal paths corresponding to the transceiver port of the second frequency band to be respectively used as a main set path and a diversity path of the second frequency band.
In the first embodiment, the first band and the second band both support CA combining, so two signal paths are selected for each band for combining configuration. For the above steps S211 and S212, any one of the following conditions should be satisfied between the selected main set path of the first frequency band and the main set path of the second frequency band, and between the selected diversity path of the first frequency band and the selected diversity path of the second frequency band: 1. respectively passing through different switches and antennas; 2. through the same switch but with different antennas. In case 2, if the two signal paths pass through the same connection path in the same switch, the register values of the paths corresponding to the two signal paths passing through the same switch should be the same, that is, the register values should be output from the same output terminal when input from the same input terminal, so as to avoid the occurrence of register value collision (i.e., physical collision). It will be appreciated that there is no physical conflict if the two signal paths pass through different connection paths of the same switch, i.e. input from different inputs and output from different outputs respectively.
Exemplarily, the main set path and the diversity path of the first frequency band may be determined first, and since the main set path and the diversity path of the same frequency band are separately designed, the same signal path may not be passed, i.e., the problem of hardware collision may not occur. Then, the major set path of the second frequency band may be determined based on the passed switch of the major set path of the first frequency band, the path register value of the corresponding switch, and the passed antenna, which are read from the above-mentioned specified list or specified database. Similarly, the diversity path of the second frequency band can be determined according to the related information of the diversity path of the first frequency band.
For example, the major set path L of the first frequency bandB1_PAnd a main set path L of the second frequency bandB2_PThe two antennas may be different from each other via different switches, as shown in fig. 5(a), or via the same switch but different antennas, as shown in fig. 5(b), where L is the sameB1_PAnd LB2_PDifferent connection paths through the same switch, and different connection paths will be connected to different antennas. Of course, if the two main set paths pass through the same connection path of the same switch, as shown in fig. 5(c), the "common path" principle should be satisfied, that is, the corresponding path register values should be the same when passing through the switch.
As a second possible implementation manner, the combined frequency band includes a first frequency band supporting the CA combination manner and a second frequency band supporting the MIMO combination manner, and as shown in fig. 6, for the step S202, the selecting of the signal path based on the anti-collision rule includes:
in the substep S221, for the first frequency band, two paths are respectively selected from the signal paths corresponding to the transceiver port of the first frequency band as a first main set path and a first diversity path of the first frequency band.
In the sub-step S222, for the second frequency band, four paths are respectively selected from signal paths corresponding to the transceiver port of the second frequency band as a second main set path, a second diversity path, a third main set path, and a third diversity path of the second frequency band, where the third main set path and the third diversity path correspond to multiple input multiple output types.
In the second embodiment, since the second frequency band supports the MIMO combination, at least four signal paths are selected for combination and configuration. Wherein, any one of the following conditions should be satisfied between the first main set path of the first frequency band and the third main set path of the second frequency band, and between the first diversity path of the first frequency band and the third diversity path of the second frequency band: 1. respectively passing through different switches and antennas; 2. passing through the same switch but through different antennas. It should be noted that for case 2, if the two signal paths pass through the same connection path in the same switch, the path register values corresponding to the two paths passing through the same switch should be the same.
And any one of the following conditions should be satisfied between the first main collecting channel and the second main collecting channel, and between the first diversity channel and the second diversity channel: 3. the antennas passing through different switches are the same; 4. through the same switch and through the same antenna. It should be noted that for this case 4, if the two signal paths pass through the same connection path in the same switch, the path register values corresponding to the two paths passing through the same switch should be the same.
For the sake of understanding, the description of the selection process is made by way of an example. For example, if the combined configuration information sent by the network side is 1a4-3a2, in this embodiment, the first frequency Band is Band 3, and the second frequency Band is Band 1, the mobile terminal queries that all signal paths (signal paths) supported by the Band 1 and Band 3 are as follows, where each following number represents a corresponding signal path.
Signal path of Band 1 is as follows:
Prx：1 3 5
Drx：2 4 6
MIMO PRX：7 9
MIMO DRX：8 10
signal path of Band 3 is as follows:
Prx：74 76
Drx：75 77
as can be seen from the above, for Band 1, four signal paths need to be selected from 10; for Band 3, two of the 4 signal paths need to be selected, and then the six selected signal paths are combined to obtain a set of MIMO combinations. For example, if two (74, 75) of Band 3 are selected as the first major set path and the first diversity path, respectively, the second major set path and the first major set path (corresponding to signal path 74) of Band 1 to be selected should satisfy: the signals respectively pass through different switches but the antennas are the same, or pass through the same switch and the same antenna, wherein the corresponding path register values of the two signals are the same when passing through the same connecting path in the same switch. Assuming that signal path 1 in Band 1 meets one of the two conditions, it can be selected.
Similarly, if the signal path 2 and the first diversity path (corresponding to signal path 75) in Band 1 satisfy one of the above two conditions, they can be selected similarly, so that the second main diversity path and the second diversity path of Band 1 can be (1, 2), respectively.
And the selection of the third main set path and the third diversity path of the Band 1 should satisfy: the first main set path (corresponding to the signal path 74) passes through different switches and antennas, or passes through the same switch but passes through different antennas, wherein the path register values of the first main set path and the second main set path are the same when the first main set path and the second main set path pass through the same connection path in the same switch. If signal path 9 in Band 1 matches one of the two situations, it can be selected.
Similarly, if the signal path 8 and the first diversity path (corresponding to signal path 75) in Band 1 satisfy one of the above two conditions, they can be selected similarly, and the third main diversity path and the third diversity path of Band 1 can be (9, 8), respectively.
It is understood that for a frequency band supporting MIMO combining, at least two main set paths and two diversity paths are included, wherein the signal path corresponding to MIMO type and the signal path corresponding to non-MIMO type will pass through different antennas. While the main diversity path (or diversity path) between different frequency bands for the same type may pass through the same antenna, e.g. a high frequency and a low frequency may pass through the same antenna.
And step S30, combining the signal paths selected by all frequency bands to be used as a carrier aggregation combination or a multi-input multi-output combination reported by the mobile terminal registration.
In step S30, after a group of CA combinations or MIMO combinations is acquired, a determination of registration failure is made. For example, whether the data amount received by each frequency band within the preset time is lower than the preset data amount may be detected, and if there is a case that at least one frequency band is lower than the preset data amount, it may be determined that the registration has failed. If not, the registration is judged to be successful, and a corresponding signaling is reported to the network equipment.
The signal path self-adaption method is applied to a mobile terminal supporting carrier aggregation and multiple input multiple output, self-adaption selection is carried out on the signal paths in the combination configuration according to a preset selection rule to obtain a CA combination or a MIMO combination reported by the mobile terminal in a registered manner, and the problem that physical conflict is easy to occur because the signal paths in the front are automatically selected from a plurality of signal paths in the prior art can be effectively solved; in addition, through intelligent configuration, a large amount of time is not needed to be spent for manually adding and checking corresponding signal path configuration, the combination configuration efficiency can be improved, and the user experience is improved.
