[0034] Typically, during uplink communication, power amplifiers in electronic devices amplify the uplink signal to increase its transmission power and improve its transmission quality, thereby enhancing overall communication quality. Related technologies utilize high-performance power amplifiers to amplify the uplink signal and improve communication quality; alternatively, they aim to improve surface mount technology (SMT) consistency and reduce production fluctuations. However, high-performance power amplifiers are expensive; while reducing production fluctuations can improve RF transmission power to some extent, it simultaneously requires higher production quality, increasing the risk of mistests or defects and ultimately reducing overall capacity.

[0035] In view of this, embodiments of this application provide an uplink communication method that can improve the uplink signal transmission power and thus improve uplink communication quality without increasing costs. Furthermore, it does not involve production lines and will not affect related production capacity.

[0036] It should be noted that the uplink communication method provided in this application embodiment can be executed by an uplink communication device. This uplink communication device can be implemented as part or all of an electronic device through software, hardware, or a combination of both. Alternatively, the uplink communication device can be located within the transceiver of an electronic device to execute the uplink communication method. The electronic device can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, smart vehicle devices, etc. Portable wearable devices can include smartwatches, smart bracelets, head-mounted devices, etc. This application embodiment does not limit the type of electronic device, as long as it has uplink communication functionality. In the following method embodiments, the execution subject is always described as an electronic device.

[0037] In one embodiment, such as Figure 1 As shown, an uplink communication method is provided, which includes the following steps:

[0038] Step 101: Obtain the link selection reference information for the electronic device.

[0039] The link selection reference information includes at least one of the communication quality information of the electronic device and the frequency band information of the frequency band in which the electronic device operates.

[0040] Communication quality information characterizes whether the current communication quality of an electronic device is high or low. For example, the environment in which an electronic device operates affects its communication quality. When an electronic device is in an environment with minimal impact on communication quality, the communication quality is high; conversely, when it is in an environment with significant impact on communication quality, the communication quality is low. For instance, an electronic device in a densely built-up area will experience low communication quality due to the buildings. Therefore, communication quality information characterizes whether the current communication environment of the electronic device is one that affects uplink communication quality, thus leading to low communication quality.

[0041] Electronic devices can operate on one or more frequency bands. A single frequency band includes, for example, cellular communication, Wi-Fi, Bluetooth, or GPS. Multiple frequency bands refer to an electronic device simultaneously using multiple frequency bands for communication; for example, an electronic device might simultaneously use a cellular communication band for cellular communication and a Bluetooth band for Bluetooth communication. When multiple frequency bands are used, the signals from each band may interfere with each other.

[0042] Step 102: Based on the link selection reference information, determine the target uplink RF link from the first uplink RF link and the second uplink RF link, and transmit the uplink signal using the target uplink RF link. The first uplink RF link includes passive components, while the second uplink RF link does not.

[0043] In other words, the electronic device selects one of the first uplink RF link and the second uplink RF link as the target uplink RF link to transmit uplink signals based on the link selection reference information.

[0044] Optionally, the uplink signal refers to the uplink cellular signal. Correspondingly, the first uplink RF link and the second uplink RF link are RF links used to transmit the uplink cellular signal.

[0045] For example, if the current communication quality is determined to be low based on communication quality information, it means that the uplink signal's transmission power is low. If the first uplink RF link, which includes passive components, continues to be used for transmission, the transmission power of the uplink signal will be further reduced after processing by the passive components. This will result in even lower quality of the uplink signal after antenna transmission, leading to poor communication quality for the electronic device. Therefore, in cases of low current communication quality, a second uplink RF link, which does not include passive components, can be used to transmit the uplink signal, eliminating the losses caused by the passive components. It should be noted that the current communication mode of the electronic device is the target communication mode. In the target communication mode, passive components are not used to process the uplink signal, and this will not affect the quality of the uplink signal.

[0046] For example, if the electronic device operates on a single frequency band, there is no influence from signals in other frequency bands. Therefore, not using passive components to process the uplink signal will not affect its quality, and a second uplink RF link can be used to transmit the uplink signal. If the electronic device operates on multiple frequency bands, the frequency band information of each band can be used to determine whether there is any interference between the signals in each band. If they do not interfere with each other, a second uplink RF link can be used to transmit the uplink signal. In this way, the quality of the uplink signal is not affected, and the loss during the uplink signal transmission process is reduced.

[0047] Optionally, the passive device can be a filter. Alternatively, other devices may be used, which are not fully illustrated here.

[0048] In the aforementioned uplink communication method, the electronic device acquires link selection reference information, including at least one of the electronic device's communication quality information and the frequency band information of the frequency band in which the electronic device operates. Based on the link selection reference information, a target uplink radio frequency link is determined from a first uplink radio frequency link and a second uplink radio frequency link, and an uplink signal is transmitted using the target uplink radio frequency link. The first uplink radio frequency link includes passive components, while the second uplink radio frequency link does not. This allows the second uplink radio frequency link, which does not include passive components, to be selected for uplink signal transmission under appropriate circumstances, based on the link selection reference information. Thus, during uplink signal transmission, there is no power loss due to the processing of passive components, effectively avoiding uplink signal power loss and ensuring high transmission power during uplink signal transmission. This ensures signal quality and, consequently, communication quality, achieving the effect of improving uplink communication quality by increasing uplink signal transmission power without increasing costs.

[0049] In one embodiment, the link selection reference information includes frequency band information. Obtaining the link selection reference information of the electronic device includes: when the electronic device is operating in TDD communication mode, obtaining the frequency band currently used by the electronic device for communication, and using the frequency band currently used by the electronic device for communication as the frequency band information.

[0050] Since the second uplink RF link does not include passive components, it is a TX SAWLESS path, where TX refers to the uplink and SAWLESS means without a filter. Because the TX SAWLESS path lacks filter suppression, there may be significant spurious signals. If the use of the TX SAWLESS path is not restricted, it could potentially damage other modules and components in the electronic device in some coexisting scenarios.

[0051] In view of this, in the embodiments of this application, when it is determined that the electronic device is operating in TDD communication mode, a target uplink radio frequency link can be further determined from the first uplink radio frequency link and the second uplink radio frequency link based on link selection reference information. That is, the primary condition for using the second uplink radio frequency link to transmit uplink signals is that the electronic device is operating in TDD communication mode. Secondly, it is necessary to further determine whether the frequency band adjacency condition is met based on frequency band information, and whether the electronic device is in an environment where the communication quality is less than a preset communication quality threshold based on communication quality information, in order to determine whether to use the second uplink radio frequency link to transmit uplink signals.

[0052] Here, when determining whether the frequency band adjacency condition is met based on the frequency band information, it is necessary to obtain the frequency band currently used for communication by the electronic device and use the frequency band currently used for communication by the electronic device as the frequency band information to determine whether the frequency band currently used for communication meets the frequency band adjacency condition.

[0053] In one embodiment, the link selection reference information includes communication quality information. Obtaining the link selection reference information of the electronic device includes: determining the signal strength of the downlink signal currently received by the electronic device; and using the signal strength as communication quality information.

[0054] In other words, in addition to sending uplink signals, electronic devices can also receive downlink signals. If the current communication environment affects the communication quality of the electronic device, the signal strength of the received downlink signal will be relatively low. Therefore, by determining the signal strength of the downlink signal, the current communication quality of the electronic device can be determined, and thus, it can be determined that the electronic device is in an environment where the communication quality is lower than a preset communication quality threshold.

[0055] For example, extremely weak signal environments can negatively impact the communication quality of electronic devices. Extremely weak signal environments include underground or enclosed spaces, high-rise buildings or densely populated building complexes, edge coverage areas far from base stations, large event areas, and densely populated areas. Within building complexes, signals are easily blocked and reflected, leading to signal weakening. Edge coverage areas far from base stations typically have weak signals, resulting in stuttering, disconnections, and other issues that severely affect user experience.

[0056] Optionally, in addition to using the signal strength of the currently received downlink signal as communication quality information, the signal strength of the currently received downlink signal and the average signal strength of multiple downlink signals received within a historical time period can be determined, and this average value can be used as communication quality information. Optionally, the historical time period can be determined by conducting preliminary experiments to study the impact of different communication environments on the signal strength of downlink signals.

[0057] In one embodiment, such as Figure 2 A flowchart illustrating the process of determining the target uplink RF link is shown. Based on link selection reference information, the target uplink RF link is determined from the first uplink RF link and the second uplink RF link, including:

[0058] Step 201: Determine whether the frequency band adjacency condition is met based on the frequency band information to obtain the first determination result.

[0059] Among them, the frequency band adjacency condition is the condition that the frequency bands in which electronic devices operate are adjacent in the frequency domain.

[0060] In one optional implementation, the electronic device has a pre-installed frequency band adjacency table. This table contains multiple sets of correspondences between adjacent frequency bands; that is, two frequency bands that are adjacent in the frequency domain form a correspondence. Thus, the frequency band adjacency table can be queried based on the frequency band information to determine whether the frequency bands currently operating in the electronic device meet the frequency band adjacency conditions. For example, if the currently operating frequency bands include a first preset frequency band and a second preset frequency band, and the frequency band adjacency table contains a correspondence between the first preset frequency band and the second preset frequency band, then the frequency band adjacency conditions are met; otherwise, they are not.

[0061] In another alternative implementation, the distance between the frequency bands in which the electronic device operates is determined based on the frequency band information, thereby determining whether the frequency band adjacency condition is met.

[0062] Optionally, determine whether the frequency band adjacency condition is met based on the frequency band information, including:

[0063] 1. If the frequency band currently used for communication by the electronic device includes the first TDD frequency band and the target frequency band, then the frequency band adjacency condition is met, and the distance between the target frequency band and the first TDD frequency band in the frequency domain is less than a preset distance.

[0064] In other words, the electronic device operates in TDD communication mode, specifically in the first TDD frequency band. It needs to utilize the target uplink RF link to transmit uplink signals in the first TDD frequency band. Furthermore, the electronic device simultaneously operates in the target frequency band and utilizes other links to transmit signals in the target frequency band. Since the distance between the target frequency band and the first TDD frequency band in the frequency domain is less than a preset distance, meaning the first TDD frequency band and the target frequency band are adjacent frequency bands, the first determination result is determined to satisfy the frequency band adjacency condition.

[0065] For example, if the first TDD band is B34, B39, N34, or N39, then the target band could be a GPS band. If the first TDD band is B38, B40, B41, N38, N40, or N41, then the target band could be a 2.4 GHz WiFi band or a Bluetooth BT band. If the first TDD band is N79, then the target band could be a 5 GHz WiFi band. It is understood that not all combinations of first TDD bands and their corresponding target bands are described here.

[0066] 2. If the frequency band currently used for communication by the electronic device includes multiple identical second TDD frequency bands, then the frequency band adjacency condition is satisfied.

[0067] That is, the electronic device operates in TDD communication mode and on multiple identical second TDD frequency bands. For example, if the electronic device is in a dual-SIM (e.g., dual phone SIM) communication state, it operates on multiple identical second TDD frequency bands. In this case, the first determination result is that the frequency band adjacency condition is met.

[0068] For example, the second TDD band is B42, B48, N77, N78, B34, B39, N34, N39, B38, B40, B41, N38, N40, N41, or N79, etc. In dual-SIM mode, it operates, for example, on two B42 bands.

[0069] Step 202: Determine whether the electronic device is in an environment where the communication quality is less than a preset communication quality threshold based on the communication quality information, and obtain the second determination result.

[0070] In one embodiment, determining whether an electronic device is in an environment where the communication quality is less than a preset communication quality threshold based on communication quality information includes: determining whether the signal strength is less than a preset strength threshold; if the signal strength is less than the preset strength threshold, then determining that the electronic device is in an environment where the communication quality is less than the preset communication quality threshold.

[0071] The electronic device has a preset strength threshold. After identifying the signal strength of the downlink signal, the signal strength is compared with the preset strength threshold. If the signal strength is less than the preset strength threshold, it is determined that the electronic device is in an environment where the communication quality is less than the preset communication quality threshold. Conversely, if the signal strength is not less than the preset strength threshold, it is determined that the electronic device is in an environment where the communication quality is not less than the preset communication quality threshold.

[0072] Step 203: Determine the target uplink radio frequency link based on the first determination result and the second determination result.

[0073] In one embodiment, determining the target uplink radio frequency link based on the first determination result and the second determination result includes: if the electronic device is in an environment with communication quality not less than a preset communication quality threshold or meets the frequency band adjacency condition, then the first uplink radio frequency link is determined as the target uplink radio frequency link. If the electronic device is in an environment with communication quality less than the preset communication quality threshold and does not meet the frequency band adjacency condition, then the second uplink radio frequency link is determined as the target uplink radio frequency link.

[0074] In other words, if the electronic device is in an environment where the communication quality is not less than the preset communication quality threshold, it means that the current environment has little impact on the signal. The uplink signal after the antenna is transmitted will not be weakened due to the influence of the environment. Therefore, the first uplink RF link containing passive components can be used to transmit the uplink signal. In this way, the passive components can filter the signal and remove the influence of other spurious signals, and the loss of the signal caused by the passive components will not affect the overall communication quality.

[0075] If the frequency band adjacency condition is met, it means that the electronic device is in a coexistence scenario. Signals in adjacent frequency bands will affect the transmission of the uplink signal. Therefore, it is necessary to use a first uplink RF link containing passive components to transmit the uplink signal and remove the coexistence effect.

[0076] Furthermore, in TDD mode, if the electronic device is in an environment where the communication quality is less than the preset communication quality threshold and the frequency band adjacency condition is not met, it means that it is currently in an extremely weak signal environment and there is no influence of adjacent frequency band signals on the uplink signal. Therefore, the processing of passive devices can be eliminated, and the uplink signal can be transmitted using the second uplink RF link. This can reduce the power loss of the uplink signal, increase the RF conduction power of the uplink signal, and not reduce the signal quality, thereby improving the uplink communication quality of the electronic device in an extremely weak signal environment.

[0077] The process of transmitting signals is explained below.

[0078] In one embodiment, such as Figure 3 A schematic diagram of the electronic device is shown. The electronic device includes a power amplifier (PA), a first switch, a filter, and an antenna switch. The power amplifier is connected to the fixed port 11 of the first switch. The first selection port 21 of the first switch is connected to the filter, the filter is connected to the antenna switch, and the second selection port 22 of the first switch is directly connected to the antenna switch. A first uplink RF link includes the power amplifier, the first switch, the filter, and the antenna switch, and a second uplink RF link includes the power amplifier, the first switch, and the antenna switch.

[0079] Optionally, the first switch is an SPDT single-pole double-throw switch.

[0080] Here, the passive device mentioned above refers to a filter.

[0081] In this embodiment of the application, transmitting an uplink signal using a target uplink RF link includes: when the target uplink RF link is a first uplink RF link, controlling a first switch to operate in a first conducting state so that the switching path between the fixed port 11 and the first selected port 21 is conducted; when the target uplink RF link is a second uplink RF link, controlling the first switch to operate in a second conducting state so that the switching path between the fixed port 11 and the second selected port 22 is conducted.

[0082] Optionally, the transceiver in the electronic device is connected to the first switch, and the transceiver controls the first switch to operate in a first conducting state or a second conducting state.

[0083] In one embodiment, such as Figure 3 As shown, the electronic device also includes an antenna module connected to an antenna switch. The antenna module includes multiple hardware antennas that can be used to receive downlink signals. The antenna switch is connected to the antenna module in the electronic device, and the antenna module includes a hardware antenna that can transmit uplink signals.

[0084] In the first conduction state, the switching path between the fixed port 11 and the first gating port 21 is turned on, which is equivalent to connecting the PA and the filter. Therefore, after the uplink signal is amplified by the power amplifier, it is further filtered by the filter. The filtered uplink signal is transmitted to the antenna module through the antenna switch and transmitted using the corresponding hardware antenna.

[0085] In the second conduction state, the switching path between the fixed port 11 and the second selector port 22 is turned on, which is equivalent to connecting the PA and the antenna switch. Therefore, the uplink signal is directly transmitted to the antenna switch after being amplified by the power amplifier, and then further transmitted to the antenna module through the antenna switch, and transmitted using the corresponding hardware antenna.

[0086] In this embodiment, a direct connection between the first switch and the antenna switch is added to the original RF architecture containing the filter, thereby achieving the effect of reducing the loss of uplink signal transmission power at low cost.

[0087] In this embodiment of the application, in addition to adjusting the hardware path, it is also necessary to adjust the switch mapping relationship to map the actual switch switching to the actual hardware antenna, thereby realizing the correspondence between the switch switching and the actual hardware antenna transmitting the uplink signal.

[0088] In mobile communication systems, switching refers to switching between different signal paths to achieve purposes such as frequency band selection, antenna selection, or selection of different signal processing paths. These switching operations are typically implemented through register control. The basic steps of register-controlled switching are as follows:

[0089] 1) Setting the register address: Registers are usually accessed through an address bus, and different registers have different addresses.

[0090] 2) Write control values: Write specific control values ​​to the register. These values ​​will determine the state or path of the switch. For example, setting a bit to "1" may indicate that path A is selected, while setting it to "0" indicates that path B is selected.

[0091] 3) Perform a switching operation: The hardware reads the value in the register and performs the corresponding operation, such as switching to a specified frequency band or antenna.

[0092] First, a feasibility analysis of the switch switching:

[0093] Due to hardware platform limitations, the transmitting antenna used to transmit uplink signals must be a subset of the receiving antennas. That is, a hardware antenna can only be used as a transmitting antenna to transmit uplink signals if it can be used as a receiving antenna to receive downlink communication signals.

[0094] Therefore, for an RF architecture with two hardware antennas (a main receiving antenna and a diversity receiving antenna) simultaneously receiving signals, the transmitting antenna for transmitting the uplink signal transmitted by the second uplink RF link must correspond to both the main antenna and the diversity antenna. For example, if the antenna module includes antennas 4, 5, 6, and 7, as shown in Table 1, and the receiving antennas are antennas 5 and 6, then in a dual-transmit scenario, the transmitting antennas must also be antennas 5 and 6, and not antennas 7 and 4. Similarly, for an RF architecture with four hardware antennas capable of receiving signals, and the receiving antennas are antennas 4, 5, 6, and 7, then in a dual-transmit scenario, antennas 5 and 6 can be used as transmitting antennas, and antennas 4 and 7 can also be used as transmitting antennas.

[0095] (Table 1)

[0096]

[0097] Electronic devices operate with different hardware antennas under different communication states. Taking LTE or NR communication as an example, electronic devices can operate in modes such as main diversity communication and MIMO communication, as shown in Table 2. The hardware antenna for main reception is antenna 5, the antenna for diversity reception is antenna 6, the main MIMO antenna is antenna 7, and the diversity MIMO antenna is antenna 4. As mentioned above, antennas 4, 5, 6, and 7 can all be used as transmitting antennas. For example, specifically, in communication state 1, antenna 5 can be used for transmission; in communication state 2, antenna 5 can be used for transmission; in communication state 3, antenna 7 can be used for transmission; and in communication state 4, antenna 4 can be used for transmission. Here, communication states 1 to 4 all utilize the first uplink RF link to transmit uplink signals. In addition, there are communication states 5 and 6 where uplink signals are transmitted via the second uplink RF link. In these cases, antennas 4, 5, 6, and 7 can be used as corresponding transmitting antennas. For example, as shown in Table 4, in communication state 5, antenna 7 is used for transmission; and in communication state 6, antenna 4 is used for transmission.

[0098] (Table 2)

[0099] LTE / NR Antenna Port 0 Antenna Port 1 Antenna Port 2 Antenna Port 3 Antenna Port 4 emission Main set reception Diversity reception Main MIMO MIMO episodes Communication status 0 Antenna 5 Antenna 6 Antenna 7 Antenna 4 Communication status 1 Antenna 5 Communication status 2 Antenna 6 Communication status 3 Antenna 7 Communication status 4 Antenna 4 Communication status 5 Antenna 7 Communication status 6 Antenna 4

[0100] When transmitting uplink signals using different antennas, the first antenna and the antenna switch correspond to different switching states, that is, different switching paths are activated.

[0101] Since communication states 5 and 6 are mapped to antennas 7 and 4 respectively, and communication states 3 and 4 are also mapped to antennas 7 and 4 respectively, there is a conflict between them. Therefore, a virtual antenna needs to be introduced for switch mapping to avoid the conflict.

[0102] As mentioned earlier, the switching is controlled by registers. After the virtual antenna is introduced, the control registers are transferred to the ANT_DB file, where the mapping relationship is configured.

[0103] For example, virtual antennas include virtual antenna 1, virtual antenna 2, virtual antenna 3, virtual antenna 4, virtual antenna 5, virtual antenna 6, and virtual antenna 7. Hardware antenna 4 corresponds to virtual antenna 4, hardware antenna 5 corresponds to virtual antenna 5, hardware antenna 6 corresponds to virtual antenna 6, and hardware antenna 7 corresponds to virtual antenna 7. Therefore, virtual antennas 1, 2, and 3 are in an idle state. The hardware antennas used in the two newly added communication states 5 and 6 can then be configured again to correspond with the restricted virtual antennas, thus avoiding conflicts. That is, actual hardware antennas 2 and 3 do not exist; virtual antenna 2 is mapped to hardware antenna 7, and virtual antenna 3 is mapped to hardware antenna 4.

[0104] In this way, when transmitting uplink signals in communication state 3, the virtual antenna 7 is used to transmit uplink signals. At this time, the first switch is in the switching state. In the first switch switching state, the first switch connects PA and filter, and the antenna switch connects filter and antenna 7. The first uplink RF link is turned on, and the hardware antenna 7 is actually used to transmit uplink signals.

[0105] When transmitting uplink signals in communication state 4, virtual antenna 4 is used to transmit uplink signals. Corresponding to the second switch switching state, in the second switch switching state, the first switch connects PA and filter, and the antenna switch connects filter and antenna 4. The first uplink RF link is turned on, and uplink signals are actually transmitted using antenna 4.

[0106] When transmitting uplink signals in communication state 5, virtual antenna 2 is used to transmit uplink signals. Corresponding to the third switch switching state, in the third switch switching state, the first switch connects PA and filter, the antenna switch connects filter and antenna 7, the second uplink RF link is turned on, and antenna 7 is actually used to transmit uplink signals.

[0107] When transmitting uplink signals in communication state 6, virtual antenna 3 is used to transmit uplink signals, corresponding to the fourth switch switching state. In the fourth switch switching state, the first switch connects PA and filter, the antenna switch connects filter and antenna 4, the second uplink RF link is turned on, and antenna 4 is actually used to transmit uplink signals.

[0108] Furthermore, configuring the TDD band in TDD mode in the ANT_DB file means that the uplink and downlink use the same spectrum resources in a time-division multiplexing manner. This configures TX and RX to different communication states, so when TX switches on or off, RX does not switch. In other words, after TX switches, the corresponding PRX and DRX antennas do not change.

[0109] After the hardware RF architecture was modified and the switch configuration was completed, actual verification showed that the corresponding switch was performed in communication state 5 and communication state 6. The uplink signal could be transmitted through the second uplink RF link. The transmission power of the uplink signal after being transmitted through antenna 7 and antenna 4 was improved compared with the traditional technology, which met expectations.

[0110] Based on the above analysis, the process for determining the target hardware antenna in the embodiments of this application can be obtained, namely, as follows: Figure 4 The flowchart shown illustrates the process of determining the target hardware antenna. The method further includes:

[0111] Step 401: Determine the target virtual antenna corresponding to the uplink signal from among the multiple preset virtual antennas.

[0112] The multiple virtual antennas include multiple first virtual antennas and multiple second virtual antennas; in one implementation, determining the target virtual antenna corresponding to the uplink signal from the multiple preset virtual antennas includes: determining the target virtual antenna from the multiple first virtual antennas when the target uplink RF link is a first uplink RF link; and determining the target virtual antenna from the multiple second virtual antennas when the target uplink RF link is a second uplink RF link.

[0113] In this context, each of the multiple first virtual antennas corresponds one-to-one with a single hardware antenna included in the antenna module. For example, the electronic device mentioned above includes hardware antennas 4, 5, 6, and 7, and the first virtual antennas are virtual antennas 4, 5, 6, and 7.

[0114] Each of the multiple second virtual antennas corresponds one-to-one with a portion of the hardware antennas included in the antenna module. For example, in the electronic device described above, antennas 7 and 4 are used as hardware antennas for transmitting the second uplink RF link, and virtual antennas 2 and 3 are second virtual antennas, corresponding to antennas 7 and 4 respectively.

[0115] Step 402: Determine the target hardware antenna corresponding to the target virtual antenna among the multiple hardware antennas included in the antenna module.

[0116] Step 403: Control the target hardware antenna to operate so as to transmit uplink signals using the target hardware antenna.

[0117] That is, the uplink RF link of the target is turned on, and the target hardware antenna is controlled to work, and the uplink signal transmitted to the antenna module by the target hardware antenna is transmitted through the uplink RF link of the target.

[0118] In this embodiment of the application, considering the newly added second uplink radio frequency link, the mapping conflict is avoided by adjusting the correspondence between the virtual antenna and the hardware antenna, ensuring that the required hardware antenna can work regardless of whether the uplink signal is transmitted using the first uplink radio frequency link or the second uplink radio frequency link.

[0119] In one embodiment, an electronic device is provided, characterized in that it is used to perform an uplink communication method as described in any of the above embodiments. Figure 5The schematic diagram shows that the electronic device includes a transceiver, a first uplink RF link connected to the transceiver, and a second uplink RF link connected to the transceiver; wherein the first uplink RF link includes passive components, and the second uplink RF link does not include passive components. The transceiver is used to acquire link selection reference information of the electronic device, determine a target uplink RF link from the first uplink RF link and the second uplink RF link based on the link selection reference information, and control the target uplink RF link to transmit uplink signals; wherein the link selection reference information includes at least one of communication quality information of the electronic device and frequency band information of the frequency band in which the electronic device operates.

[0120] In one embodiment, such as Figure 6 A schematic diagram of another electronic device is shown, which also includes a power amplifier PA, a first switch, a filter, and an antenna switch. The power amplifier is connected to the fixed port 11 of the first switch, the first selection port 21 of the first switch is connected to the filter, the filter is connected to the antenna switch, and the second selection port 22 of the first switch is directly connected to the antenna switch. The first uplink RF link includes the power amplifier, the first switch, the filter, and the antenna switch, and the second uplink RF link includes the power amplifier, the first switch, and the antenna switch.

[0121] The transceiver is used to control the first switch to operate in a first conducting state when the target uplink RF link is a first uplink RF link; and to control the first switch to operate in a second conducting state when the target uplink RF link is a second uplink RF link; the first switch is used to connect the fixed port 11 and the first strobe port 21 in the first conducting state; and to connect the fixed port 11 and the second strobe port 22 in the second conducting state.

[0122] In one embodiment, continue to refer to Figure 6 As shown, the electronic device also includes an antenna module, which includes multiple hardware antennas that can be used to receive downlink signals. The antenna module is connected to an antenna switch.

[0123] The transceiver is also used to control the antenna switch to connect the filter and the antenna module when the first uplink RF link is determined to be the target uplink RF link. Thus, under the action of the first switch and the antenna switch, the first uplink RF link is activated. Understandably, the second uplink RF link is not activated at this time.

[0124] The transceiver is also used to control the antenna switch to connect the second gating port 22 and the antenna module when the second uplink RF link is determined to be the target uplink RF link. Thus, under the action of the first switch and the antenna switch, the second uplink RF link is activated. It is understood that the first uplink RF link is not activated at this time.

[0125] Figure 6 This example uses only two hardware antennas; in practical applications, an antenna module can include more than two hardware antennas. When the number of output ports of an antenna switch is less than the total number of hardware antennas, the antenna switch cannot connect to all hardware antennas. Therefore, in some cases, the antenna switch can include multiple switches with a greater number of output ports, thus enabling connection to all hardware antennas.

[0126] Please refer to Figure 7 The diagram shows another electronic device, in which the antenna switch includes a second switch and a third switch connected to the second switch; the multiple hardware antennas include a first antenna connected to the second switch and multiple second antennas connected to the third switch. Here, the first antenna is... Figure 7 Antenna 5 in the middle, the second antenna is Figure 7 Antennas 4, 6, and 7 are included. Furthermore, the third switch is connected to the second switch via line A.

[0127] The transceiver is also used to control the second switch to connect the filter and the first antenna when the first uplink RF link is determined to be the target uplink RF link. At this time, the uplink signal transmitted by the first uplink RF link can be transmitted using the first antenna.

[0128] Alternatively, the transceiver can control a second switch to connect a filter and a third switch when the first uplink RF link is determined to be the target uplink RF link, and control the third switch to connect the second switch and a first target antenna among a plurality of second antennas. In this case, the uplink signal transmitted by the first uplink RF link can be transmitted using the first target antenna.

[0129] The transceiver is also used to control a third switch to connect a first switch and a second target antenna among a plurality of second antennas, when the second uplink RF link is determined to be the target uplink RF link. At this time, the uplink signal transmitted via the second uplink RF link can be transmitted using the second target antenna.

[0130] Optionally, the third switch is a 3P3T switch.

[0131] Optional, see reference Figure 7 As shown, the electronic device also includes a DC-DC radio frequency power management chip connected to the transceiver and the PA. A first switch is also connected to the transceiver.

[0132] For example, during the operation of the electronic device, the transceiver modulates the signal and transmits it to the PA (Power Amplifier). It also controls the RF power management chip via the MIPI bus to output a power supply voltage to the PA, and simultaneously controls the PA's operation via the MIPI bus. The PA amplifies the transmitted signal. The RF power management chip, controlled by the transceiver, supplies power to the PA. The first switch is an SPDT switch. The transceiver controls the first switch via GPIO. When the switch is set to "port 21", the transmit signal (TX) passes through the filter path; when the switch is set to "port 22", the TX skips the filter path. The filter is used to filter the transmitted signal. The antenna switch selects the operating frequency band. Each antenna is used to transmit uplink signals.

[0133] Figure 7 In the architecture shown, the uplink signal loss of the filter and the second switch is 3 to 5 dB greater than the insertion loss of the B trace between the first and third switches. Theoretically, by skipping the filter and the first switch, the uplink signal transmission power can be increased, which can help to greatly improve the signal coverage of electronic devices and achieve high-quality signal transmission.

[0134] also, Figure 7 In the architecture, the A-line RF trace between the second and third switches is inconsistent with the B-line RF trace, resulting in differences in their losses. Therefore, the actual TX boost power at the antenna end differs from the theoretically calculated value. As shown in Table 3, for low, medium, and high channels in a certain frequency band, skipping the filter reduces signal loss by 4.8dB, 3.1dB, and 5.0dB, respectively. The nearly 2dB difference in loss between different channels is due to the inherent characteristics of the device. Combining the losses of trace B, the first switch, and trace A, the power gains are 3.5dB, 1.7dB, and 3.6dB, respectively.

[0135] (Table 3)

[0136]

[0137] In one embodiment, please refer to Figure 8 The schematic diagram of another electronic device shown includes an antenna switch comprising a second switch and a third switch connected to the second switch; and multiple hardware antennas comprising a first antenna connected to the second switch and multiple second antennas connected to the third switch.

[0138] The transceiver is also configured to, when determining that the first uplink RF link is the target uplink RF link, control the second switch to connect the filter and the first antenna, or control the second switch to connect the filter and the third switch, and control the third switch to connect the second switch and the first target antenna among a plurality of second antennas.

[0139] The transceiver is also configured to, when determining that the second uplink RF link is the target uplink RF link, control the second switch to connect the first switch and the first antenna, or control the second switch to connect the first switch and the third switch, and control the third switch to connect the second switch and the second target antenna among a plurality of second antennas.

[0140] That is to say, Figure 7 The first switch in the middle is specifically connected to the third switch, and Figure 8 The first switch is specifically connected to the second switch. Thus, Figure 8 Antenna 5 can also be used to transmit uplink signals transmitted via the second uplink RF link. This change will reduce the use of the input port of the third switch to accommodate more complex RF structure designs. The B trace represents the uplink signal being transmitted directly to the second switch without passing through a filter. Theoretically, whether the TX signal of the same antenna skips the filter or not will result in a power difference of about 3 to 5 dB. However, the different RF traces after passing through the switch lead to different RF path losses, so the actual power gain differs from the theoretical value. As shown in Table 4:

[0141] (Table 4)

[0142]

[0143] As can be seen from Tables 3 and 4, Figure 7 and Figure 8 The power gains resulting from different architectural designs are different, and Figure 7 The power increase of the structure is significant, ranging from 1.7 to 3.6 dB. A comparison of the two structures reveals that the inconsistent B-line routing in the two architectures leads to the use of different switches. A comparison of their losses shows... Figure 8 Significant losses occurred during the process, resulting in Figure 8 The power gain in the structure only increased by 0.5 to 2.3 dB. However, despite Figure 8 The intermediate structure only improves signal transmission power by 2.3dB, but it reduces the occupancy of the input port of the third switch. If there are no other RF requirements, besides using a 3P3T configuration, the third switch can also be set as a DPDT switch, still achieving the goal of increasing signal transmission power while reducing cost (DPDTs are cheaper than 3P3Ts), and the results are still as expected. Both structures improve signal transmission power by adding a first switch without changing the original RF architecture, thus enhancing the uplink communication capability of the electronic device.

[0144] To facilitate understanding, a specific embodiment will be used below. Figure 7 or Figure 8 The uplink communication process of the electronic device shown is explained.

[0145] Because the TX SAWLESS path lacks filter suppression, it exhibits significant spurious signals. Without restrictions on entry scenarios, it could potentially damage other modules and components in the mobile terminal during coexistence. Considering the TX SAWLESS solution is applicable to TDD bands, the primary condition for entering the TX SAWLESS path is operation within a TDD band. Secondly, the TX SAWLESS solution's greatest benefit lies in maximum power scenarios, so the second condition for entry must be extremely weak signal scenarios. Finally, there is the limitation of coexistence scenarios: when an adjacent band is detected operating simultaneously within the current TDD band, this solution restricts entry into the TX SAWLESS path. The specific software implementation flowchart is as follows... Figure 9 As shown:

[0146] 1) First, detect the network status of the electronic device to identify cellular communication and WIFI / BT / GPS communication;

[0147] 2) Detect whether the cellular network of the electronic device is working in TDD mode. If not, the transceiver controls the first switch to "21" via GPIO, and TX passes through the filter path; otherwise, proceed to the next step.

[0148] 3) Detect whether the electronic device has entered an extremely weak signal scenario. If not, the transceiver controls the first switch to "22" via GPIO, and TX passes through the filter path; otherwise, proceed to the next step.

[0149] 4) Detect the operating frequency band of the electronic device. If it is operating in the 34 / 39 / 38 / 40 / 41 / 42 / 48 / 77 / 78 / 79 frequency band, proceed to the next step. If it is operating in other frequency bands, the transceiver controls the SPDT switch to "21" through GPIO, and TX passes through the filter path.

[0150] 5) When the electronic device is operating in the 34 / 39 frequency band, check if the electronic device has GPS enabled. If enabled, the transceiver controls the SPDT switch to "21" via GPIO, and TX passes through the filter path. Otherwise, proceed to the next step and continue to check if the electronic device is operating in dual-SIM mode in the 34 / 39 frequency band. If it is operating in dual-SIM mode in the 34 / 39 frequency band, the transceiver controls the SPDT switch to "21" via GPIO, and TX passes through the filter path. Otherwise, the transceiver controls the SPDT switch to "22", and TX skips the filter path.

[0151] 6) When the electronic device is operating on the 38 / 40 / 41 frequency band, check if the electronic device has 2.4G WIFI or BT enabled. If enabled, the transceiver controls the SPDT switch to "21" via GPIO, and TX passes through the filter path. Otherwise, proceed to the next step and continue to check if the electronic device is operating in dual-SIM mode on the 38 / 40 / 41 frequency band. If it is operating in dual-SIM mode on the 38 / 40 / 41 frequency band, the transceiver controls the SPDT switch to "21" via GPIO, and TX passes through the filter path. Otherwise, the transceiver controls the SPDT switch to "22", and TX skips the filter path.

[0152] 7) When the electronic device is working in the 42 / 48 / 77 / 78 frequency band, detect whether the electronic device is working in the dual-card state of the 42 / 48 / 77 / 78 frequency band. If so, the transceiver controls the SPDT switch to "21" through GPIO, and TX passes through the filter path. Otherwise, the transceiver controls the SPDT switch to "22", and TX skips the filter path.

[0153] 8) When the electronic device is operating on band 79, check if the electronic device has 5G WIFI enabled. If enabled, the transceiver controls the SPDT switch to "21" via GPIO, and TX passes through the filter path. Otherwise, proceed to the next step and continue to check if the electronic device is operating in dual-SIM mode on band 79. If it is operating in dual-SIM mode on band 79, the transceiver controls the SPDT switch to "21" via GPIO, and TX passes through the filter path. Otherwise, the transceiver controls the SPDT switch to "22", and TX skips the filter path.

[0154] 9) In the TX SAWLESS path, because the insertion loss is relatively small, the uplink coverage can be enhanced by increasing the target power response of the electronic device according to the actual link loss.

[0155] In this embodiment, the design based on the original RF architecture mainly consists of two parts: one part is to use a low insertion loss first switch to skip passive components such as filters in the hardware path, thereby reducing passive losses in the TX path and increasing the transmission power of the mobile terminal; the other part is to adjust the switch mapping relationship in the RF system, mapping the actual switch switching to a virtual antenna (which does not exist in hardware), and the virtual antenna to the actual physical antenna, thereby realizing the correspondence between switch switching and the actual transmission antenna. For the TDD band, in extreme weak network scenarios, through switch control, the RF PA skips the filter path and reaches the antenna through the TX SAWLESS path. In this way, by saving the loss caused by the filter, the RF conducted power can be improved, achieving the effect of low-cost simplification of the RF solution, reducing front-end loss and improving the uplink signal RF conducted power. Overall, the TX sawless solution can improve the signal RF conducted power by 3dB, double the uplink coverage, implement the TX SAWLESS solution through switch switching, and restrict the TX SAWLESS conditions through scene recognition to avoid compliance issues.

[0157] Based on the same inventive concept, this application also provides an uplink communication device for implementing the uplink communication method described above. The solution provided by this device is similar to the implementation described in the above method; therefore, the specific limitations in one or more uplink communication device embodiments provided below can be found in the limitations of the uplink communication method described above, and will not be repeated here.
