Technical Field

[0001] This application relates to the field of electronic technology, and includes, but is not limited to, a signal control method and a terminal. Background Technology

[0002] Multi-antenna technology is widely used in communication systems such as 5G, enhanced 5G (5G+), 4G, and WLAN to improve communication speed and network coverage. Common applications include Multiple-Input Multiple-Output (MIMO) and Transmit Diversity (TXD) technologies. MIMO transmits data simultaneously through multiple antennas to increase channel capacity, while TXD transmits the same signal through multiple antennas to enhance signal coverage and stability.

[0003] When related technologies simultaneously implement uplink multiple-input multiple-output (UL-MIMO) or uplink transmit diversity (UL TXD) on fixed dual antennas, they do not consider the mutual constraints between UL-MIMO, UL TXD, uplink single-input single-output (UL-SISO), and operating power consumption, and can only run all technical services under a compromise performance.

[0004] Since existing technologies fail to consider the impact of antenna gain imbalance on performance and power consumption, dynamic antenna configuration optimization for different communication states is an urgent problem to be solved. Summary of the Invention

[0026] Among related technologies, the application of MIMO technology can provide users with a significantly increased speed experience, while multi-antenna signal enhancement technology can broaden network coverage and reduce user network drops.

[0027] In related technologies, the rationality of antenna configuration can be judged based on antenna correlation (such as the correlation envelope coefficient (ECC)). However, in practical applications, the impact of antenna radiation gain imbalance is not considered, especially in TXD mode. When the radiation gain between the two antennas is unbalanced, even if both antennas are activated, the performance gain is very limited. Continuing to maintain dual-antenna transmission in this situation will cause the power amplifier to operate simultaneously, resulting in unnecessary power consumption increases. Due to the requirements of 3GPP standards on transmit interference and isolation, the actual gain effect of dual antennas is further limited.

[0028] To address the problems existing in related technologies, this application proposes a signal control method. This method dynamically identifies the antenna's operating mode based on the terminal's communication status and adjusts the antenna configuration according to the requirements of different modes. In MIMO mode, antenna correlation is reduced, thereby increasing the data transmission rate; while in TXD mode, antenna correlation is appropriately increased to enhance signal strength.

[0029] The embodiments of this application achieve a balance between improving MIMO performance and reducing TXD power consumption by dynamically adjusting the antenna configuration and optimizing control based on signal correlation.

[0030] In some embodiments, the signal control method provided in this application can be executed by a terminal device, which can be a mobile communication terminal that supports MIMO or multi-antenna diversity transmission, such as a smartphone or tablet computer.

[0031] The technical solution of this application will now be described in detail with reference to the accompanying drawings.

[0032] Figure 1 This is an optional flowchart illustrating the signal control method provided in the embodiments of this application. Figure 1 ,like Figure 1 As shown, the terminal is the executing entity of the signal control method. The signal control method provided in this application embodiment can be implemented through steps S101 to S103:

[0033] Step S101: Determine the current antenna operating status of the terminal based on the terminal's communication status.

[0034] Here, the antenna operating status of the terminal can be determined based on the current communication status. The antenna operating status can be the status of multiple / multiple types of antenna combinations in the terminal, such as multiple-input multiple-output status or diversity transmission status.

[0035] Communication status can include information such as the terminal's current signal strength, signal quality, channel status, terminal mobility, and antenna configuration capabilities. Based on this information, the terminal's current antenna operating status can be determined.

[0036] Step S102: When the antenna is in the multiple input multiple output state, adjust the antenna configuration of the multiple antennas until the signal correlation between the multiple antennas is less than a first threshold.

[0037] In this embodiment, Multiple-Input Multiple-Output (MIMO) refers to the simultaneous transmission and reception of multiple independent data streams using multiple transmit and receive antennas, thereby improving the spectral efficiency and throughput of the terminal. To ensure good performance of MIMO, low correlation between the antennas is required, meaning minimal interference between their signals.

[0038] Antenna configuration refers to the physical arrangement of antennas within a terminal and their electrical characteristics, such as antenna spacing, polarization direction, and feed point location. Technicians can effectively alter the signal correlation between antennas by adjusting the antenna configuration, thereby affecting MIMO (Multiple-Input Multiple-Output) performance. Antenna configurations can also involve multiple antennas, with operating status referring to whether the antennas are in transmit, receive, or idle states. For example, when a terminal switches to MIMO mode, it may activate two antennas for both transmit and receive; while in diversity mode, the terminal may only activate the first antenna for transmit, reserving the second antenna as a backup.

[0039] Here, the degree of signal correlation can be represented by the Envelope Correlation Coefficient (ECC), with a value ranging from 0 to 1. In MIMO mode, it is desirable to have the lowest possible signal correlation. Therefore, a first threshold can be preset. If the terminal is in MIMO mode, the terminal can adjust the antenna configuration of the multiple antennas so that the ECC between the multiple antennas is less than the first threshold, thereby reducing interference between antennas and improving the performance of the terminal in MIMO mode.

[0040] The first threshold represents the maximum allowable signal correlation in multiple-input multiple-output (MIMO) mode. Here, the first threshold can be 0.2. The first threshold is used to determine whether the signal correlation between antennas is low enough to meet the performance requirements of MIMO mode. For example, in a dual-antenna MIMO mode, if the signal correlation is 0.18, it indicates that the interference between the two antennas is very small, meeting the ideal conditions for MIMO operation.

[0041] Adjusting the antenna configuration can be done in a dual-antenna MIMO terminal, where the antennas are reconfigurable. This involves adjusting the distance between the two antennas or rotating the orientation of one of the antennas to reduce the correlation between them.

[0042] In this embodiment, the terminal can continuously detect the ECC value between the antennas and adjust the antenna configuration to keep the ECC value below a first threshold, thereby ensuring the stability and efficiency of multiple-input multiple-output state data transmission.

[0043] Step S103: When the antenna is in diversity transmission mode, the antenna configuration is adjusted based on the signal strength difference between multiple antennas until the signal correlation is greater than a second threshold; wherein the second threshold is greater than the first threshold.

[0044] In this embodiment, diversity transmission uses multiple antennas to transmit the same or similar data to improve signal reliability and stability. In diversity transmission, the higher the correlation between antennas, the greater the gain after signal synthesis; therefore, it is necessary to appropriately increase the ECC value.

[0045] Signal strength difference refers to the variation in downlink signal strength received by multiple antennas on a terminal. A large signal strength difference indicates a significant difference in signal quality between the two antennas. In this case, diversity transmission may not provide significant gain and can lead to unnecessary increases in power amplifier (PA) power consumption.

[0046] This application embodiment can introduce signal strength difference as a judgment criterion. When the terminal is in diversity transmission state, the antenna configuration is adjusted so that the signal correlation is greater than the second threshold, thereby improving the signal enhancement effect.

[0047] The second threshold represents the minimum signal correlation required in diversity transmission mode; here, the second threshold can be 0.8. The second threshold can be used to determine whether the correlation between antennas is high enough to meet the signal enhancement requirements of diversity transmission mode. For example, in a dual-antenna diversity transmission mode, if the signal correlation is 0.85, it indicates that the signal consistency between the two antennas is high, and the signal can be enhanced in diversity transmission mode.

[0048] For example, in a dual-antenna diversity transmission configuration, if the two antennas are installed at a distance and in different directions, it may result in a lower ECC value. In this case, the correlation can be improved by shortening the antenna spacing or adjusting the antenna orientation, so that the correlation reaches or exceeds the second threshold.

[0049] In the application embodiment, the antenna configuration can be dynamically adjusted according to the signal strength difference, and the terminal ensures that the signal correlation is higher than the second threshold, thereby reducing unnecessary power consumption while enhancing the signal.

[0050] The embodiments of this application can dynamically identify the antenna operating mode and adjust the antenna configuration accordingly, thereby reducing antenna correlation to improve data transmission rate in multiple input multiple output mode and increasing antenna correlation to enhance signal strength in diversity transmission mode, effectively reducing terminal power consumption and improving overall energy efficiency.

[0051] This application's embodiments determine the antenna operating state based on the terminal's communication state. In MIMO mode, the antenna configuration is adjusted to reduce the signal correlation to below a first threshold, thereby improving MIMO performance. In TXD mode, the antenna configuration is adjusted to increase the signal correlation to above a second threshold, thereby enhancing signal coverage and gain. By dynamically switching antenna configurations to improve performance under different communication states, under strong signal conditions, the antenna can be switched to a scheme with a small ECC between uplink antennas to achieve maximum throughput; under weak signal conditions, it can switch to a scheme with a large ECC to increase the antenna's radiation similarity, thereby improving the antenna's scalability and solving the problem in related technologies where MIMO and TXD performance cannot be simultaneously achieved.

[0052] In some embodiments, Figure 2 This is an optional flowchart illustrating the signal control method provided in the embodiments of this application. Figure 2 ,like Figure 2 As shown, the signal control method provided in this application embodiment further includes steps S201 to S203:

[0053] Step S201: When the communication state is diversity transmission state and the signal correlation is greater than the second threshold, obtain the downlink signal strength of each antenna in the multi-antenna system.

[0054] In this embodiment, downlink signal strength refers to the signal power level measured by the terminal device when receiving signals from a base station or other communication nodes. Downlink signal strength reflects the communication quality between the terminal and the base station and can be expressed in decibels per milliwatt (dBm). Here, the downlink signal strength of each antenna can be obtained by reading real-time data provided by the modem module, and subsequent judgments can be made based on these signal strength values.

[0055] Here, in diversity transmission mode, if the signal correlation is higher than the second threshold, it indicates that the signals received by multiple antennas have good consistency.

[0056] Step S202: Based on the downlink signal strength of each antenna, determine the downlink signal strength difference between multiple antennas.

[0057] Here, downlink signal strength difference refers to the difference in downlink signal strength between two or more antennas. This difference can be expressed as an absolute value, in decibels (dB). For example, if antenna A has a downlink signal strength of -85 dBm and antenna B has a downlink signal strength of -89 dBm, then the signal strength difference between them is 4 dB. This difference may be caused by factors such as antenna location, environmental interference, and path loss.

[0058] By comparing the downlink signal strength of each antenna, the maximum difference between the multiple antennas can be calculated, and this maximum difference is used as the basis for determining whether to disable TXD. When the downlink signal strength difference between the multiple antennas exceeds a strength threshold (e.g., 4dB), the signal enhancement effect of the dual antennas will significantly decrease, and continuing to maintain TXD mode will increase unnecessary power consumption.

[0059] Figure 3 This is a schematic diagram illustrating the relationship between uplink gain enhancement and antenna imbalance in the communication system 2 provided in this application embodiment. Curve 301 is the corresponding curve for gain enhancement and antenna imbalance in the uplink of system 2. When the antenna imbalance reaches 4dB, the gain enhancement brought by dual antennas is less than 1.5dB. At the same time, due to 3GPP requirements for interference and isolation in transmission, there will be an additional maximum power reduction (MPR), making the gain increase achieved by dual antennas even smaller. At this point, the effect of two transmissions on TXD is already very small, while the power amplifiers corresponding to the two transmission signals are still turned on simultaneously, resulting in a significant increase in power consumption.

[0060] By calculating the downlink signal strength difference between multiple antennas, it is possible to effectively identify signal imbalances between antennas and dynamically adjust the antenna operating mode according to actual communication needs.

[0061] Step S203: Based on the downlink signal strength difference, data is transmitted based on at least one uplink channel of the multiple antennas.

[0062] Data transmission based on downlink signal strength differences aims to make efficient use of antenna resources while ensuring communication quality. For example, when a large downlink signal strength difference is detected between multiple antennas, it indicates that the signal enhancement capability of these antennas is limited. In this case, it is possible to select only one antenna among the multiple antennas for uplink data transmission and to shut down the transmission channel corresponding to the unused antenna, thereby reducing power consumption.

[0063] At least one uplink channel means that during uplink communication, the terminal can choose to use one or more antennas to transmit data. When it is determined that the signal imbalance between multiple antennas is serious, the transmission channel on the low signal path can be shut down by controlling the transceiver module, and the corresponding power amplifier can also be turned off to optimize power consumption.

[0064] By adjusting the uplink channel data transmission strategy based on the downlink signal strength difference, the power consumption of the terminal can be effectively reduced without affecting the user's communication experience. This not only improves the device's battery life but also reduces unnecessary energy waste.

[0065] This application's embodiments introduce downlink signal strength difference as a judgment criterion in TXD state, combined with uplink channel data transmission strategy, so that the terminal can dynamically adjust the transmission path according to actual signal conditions, avoiding the continued use of high-power dual-path transmission under low gain conditions, thereby effectively reducing terminal power consumption.

[0066] In some embodiments, step S203 may include step S2031:

[0067] Step S2031: In response to the downlink signal strength difference being less than a strength threshold, data transmission is performed based on all uplink channels of the multiple antennas; wherein the downlink signal strength difference is inversely proportional to the gain enhancement between the multiple antennas.

[0068] In some embodiments, the strength threshold can be a preset signal difference threshold value, used to determine whether the conditions for enabling all uplink channels are met. When the actual measured downlink signal strength difference is less than the strength threshold, it indicates that the signal consistency between antennas is good, making it suitable to enable all uplink channels to improve transmission performance. The strength threshold can be set according to specific application scenarios, communication standards (such as 5G NR), or device characteristics, for example, 4dB, 6dB, etc.

[0069] An uplink channel refers to the communication path used by a terminal to transmit data to a base station via multiple antennas. Each uplink channel corresponds to an antenna transmission path and is driven by a power amplifier. Using multiple uplink channels can improve data transmission rate or signal coverage, and in TXD mode, it can enhance signal reliability.

[0070] Here, the downlink signal strength difference is inversely proportional to the gain enhancement between multiple antennas, which means that when the signal difference between multiple antennas is small, the cooperative effect of multiple antennas is better, thus bringing higher link gain.

[0071] The embodiments of this application utilize all uplink channels for data transmission in a good signal environment, i.e., when the downlink signal strength difference is small. This can make full use of all uplink channels, improve data transmission efficiency and user experience, and reduce unnecessary power consumption.

[0072] In some embodiments, data transmission based on all uplink channels of the multi-antenna system in step S2031 can be achieved through steps S1 and S2:

[0073] Step S1: In response to the data request command sent by the base station, generate a control signal that includes at least radio frequency control information, power allocation information and encoding information.

[0074] In some embodiments, when a terminal device receives a data request instruction from a base station, the baseband processing module inside the terminal device generates a control signal containing various control parameters based on the current communication environment and user requirements. The control signal may include radio frequency control information, power allocation information, and encoding information. Specifically, the radio frequency control information indicates on which frequency resource the terminal device should transmit data; the power allocation information determines the transmission power on each transmission path to optimize power consumption and coverage; and the encoding information determines the modulation method and coding rate of the data, thereby affecting transmission efficiency and reliability.

[0075] The modem module inside the terminal device can decode the control commands sent by the base station and generate the final control signal by combining the local status (such as channel quality, battery power, etc.). The transceiver then converts the control information into actual radio frequency signals and outputs them to the antenna.

[0076] Step S2: Based on the control signal, activate all uplink channels of the multi-antenna system and send the data corresponding to the data request instruction to the base station through all uplink channels.

[0077] Here, after the control signal containing radio frequency control information, power allocation information, and coding information is generated, the terminal device will activate all available uplink channels based on the content of the control signal. The transceiver can adjust the PA output power of each transmit channel according to the power allocation information; select the correct frequency resources according to the radio frequency control information; set the corresponding modulation and coding parameters according to the coding information; and finally, the terminal device will simultaneously transmit the prepared data to the base station through all activated uplink channels, realizing multi-antenna parallel uplink transmission.

[0078] This application embodiment enables all uplink channels of multiple antennas based on control signals, which can flexibly adapt to communication conditions in different scenarios while meeting uplink transmission requirements, thereby improving transmission efficiency and reducing unnecessary power consumption. In particular, it can further optimize overall communication performance when antennas are unbalanced.

[0079] In some embodiments, step S203 may further include steps S2032 and S2033, wherein steps S2032 and S2033 are parallel to step S2031.

[0080] Step S2032: In response to the downlink signal strength difference being greater than the strength threshold, determine the channel operating state of all uplink channels in the diversity transmission state.

[0081] In some embodiments, when the downlink signal strength difference exceeds a preset strength threshold, it indicates that there is a significant difference in the receiving capabilities of the two antennas, which will affect the gain effect of transmit diversity.

[0082] The uplink channel operating status refers to whether each uplink channel has the ability to operate normally, and can include comprehensive information such as operating status (i.e., whether it is being used), signal quality, resource usage, transmission capacity, and health status.

[0083] Step S2033: In response to the channel working state indicating that all uplink channels are in working state, determine the target uplink channel that meets the target conditions among all uplink channels of the multi-antenna system, and perform data transmission based on the target uplink channel.

[0084] Here, if multiple uplink channels are all active, it means that the terminal has the ability to use multiple uplinks simultaneously.

[0085] In some embodiments, the target conditions may include at least one of the following: best signal quality, lowest latency, and widest bandwidth. Depending on the requirements of the current communication scenario, the target conditions can be dynamically adjusted based on network scheduling strategies, user needs, or terminal resource availability. In low-latency applications, the channel with the lowest latency can be selected; in high-throughput scenarios, the channel with the largest bandwidth can be prioritized.

[0086] The target uplink channel can refer to at least one uplink channel among multiple uplink channels that meets the target conditions. This application can reduce the additional power consumption caused by activating multiple channels while ensuring the efficiency and stability of data transmission.

[0087] In the diversity transmission mode of this application embodiment, when the downlink signal strength difference is large, it indicates that the signals of the two antennas are significantly different. At this time, continuing to use the dual uplink channels may lead to a decrease in gain and an increase in power consumption. Therefore, it is possible to selectively use part of the uplink channel, which can not only optimize the transmission quality, but also reduce power consumption.

[0088] In some embodiments, step S2033 can be implemented by steps S11 and S12:

[0089] Step S11: Based on the downlink signal strength of each antenna, determine the downlink channel with the highest downlink signal strength.

[0090] The embodiments of this application can compare the downlink signal strength of each antenna to determine which antenna has the best communication environment, ensuring that subsequent data transmission selects the most reliable path, thereby improving overall communication efficiency and reliability.

[0091] Step S12: Determine the uplink channel corresponding to the downlink channel as the target uplink channel, and send data to the base station through the target uplink channel.

[0092] In some embodiments, the target uplink channel refers to the specific channel selected for data transmission. The target uplink channel is selected based on the antenna corresponding to the strongest downlink signal strength. This is because there is symmetry between the downlink and uplink channels; selecting the uplink channel corresponding to the antenna with the strongest downlink signal strength can maximize the stability and speed of uplink transmission.

[0093] Here, when the downlink signal strength of a certain antenna is detected to be higher than that of other antennas, the antenna corresponding to the uplink channel with the highest downlink signal strength will be automatically set as the target uplink channel, and the transmission path of the non-target uplink channel will be closed.

[0094] In the transmit diversity scenario, this application embodiment uses the uplink channel corresponding to the channel with the stronger downlink signal as the target channel for data transmission, which can optimize communication performance and reduce power consumption of the terminal device.

[0095] In some embodiments, the signal control method provided in this application may further include steps S21 and S22:

[0096] Step S21: In response to the terminal transmitting data based on the target uplink channel, determine the target power amplifier other than the power amplifier corresponding to the target uplink channel among all power amplifiers.

[0097] Here, when a terminal transmits data through a target uplink channel, it identifies the power amplifier used by that target uplink channel and excludes the power amplifier corresponding to that target uplink channel from all available power amplifiers, thus determining the target power amplifier. This identifies power amplifiers that are currently unused and can be turned off to save power. In a multi-antenna configuration, this reduces resource waste caused by unnecessary continuous operation of power amplifiers.

[0098] For example, in a dual-antenna terminal, if only antenna 1 is currently used for uplink transmission, the power amplifier PA1 corresponding to antenna 1 is working. The power amplifier PA2 connected to antenna 2 can be identified as the target power amplifier, which is the power amplifier that can be turned off.

[0099] Step S22: Turn off the target power amplifier on the uplink of the terminal.

[0100] In this embodiment, once the target power amplifier is identified, a shutdown operation will be performed, that is, power supply to the target power amplifier will be stopped or the target power amplifier will be put into a low power state. Shutting down non-target power amplifiers can significantly reduce the overall power consumption of the terminal. Especially when the uplink signal strength difference is large and the TXD gain is close to saturation, shutting down redundant non-target power amplifiers will not affect the communication performance, but can effectively extend the power supply time of the terminal and achieve energy saving effect.

[0101] This application embodiment dynamically determines the current uplink channel usage of the target and shuts down the target power amplifier, thereby achieving effective power consumption control and reducing terminal energy consumption without sacrificing communication quality.

[0102] In some embodiments, the terminal includes an antenna reconfigurable device. An antenna reconfigurable device can refer to a hardware module capable of dynamically changing its operating state according to communication requirements. The antenna reconfigurable device integrated in the terminal achieves switching of multiple antenna parameters through control circuits, switching matrices, tunable elements, etc. In MIMO mode, the antenna reconfigurable device integrated in the terminal can adjust the correlation between multiple antennas to achieve a low correlation coefficient (i.e., low ECC), thereby improving the data transmission rate; while in TXD mode, the antenna reconfigurable device integrated in the terminal can increase the correlation between multiple antennas to achieve a high correlation value (i.e., high ECC), thereby enhancing signal coverage.

[0103] Correspondingly, the adjustment of the antenna configuration of multiple antennas provided in this application embodiment can be achieved through step S31:

[0104] Step S31: Based on the reconfigurable antenna device, adjust the structure or electrical configuration of the multiple antennas.

[0105] In this embodiment, the reconfigurable antenna device provides a mechanism for adjusting the structure or electrical configuration of multiple antennas. It can reduce the correlation between multiple antennas in MIMO mode to improve data transmission efficiency, and increase the correlation between multiple antennas in TXD mode to enhance signal coverage. This approach combines the advantages of multi-antenna technology in both high-speed data transmission and signal enhancement, thereby significantly improving the adaptability and energy efficiency of the terminal in complex communication environments.

[0106] Here, "structure" refers to the physical configuration of multiple antennas, including their geometry, dimensions, and spatial distribution. For example, the radiator length can be the length of the antenna arms, which affects the corresponding resonant frequency; the shape can be rectangular, circular, L-shaped, etc., affecting the corresponding radiation pattern; the feed point location refers to the position where the multiple antennas are excited, affecting the corresponding input impedance and matching characteristics; and the number of grounding points determines the coupling degree between the multiple antennas and the ground plane, affecting the corresponding bandwidth and gain characteristics.

[0107] Electrical configuration refers to altering the electromagnetic characteristics of multiple antennas by adjusting their internal circuit parameters. For example, load impedance is the resistance value connected to the output terminals of the multiple antennas, which affects the energy transmission efficiency of the load impedance; feed phase is the phase difference between the multiple antenna elements, which affects beamforming and directivity. By adjusting these parameters, technicians can dynamically optimize the performance of multiple antennas.

[0108] Reconfigurable antenna devices enable flexible control over the performance of multiple antennas by collaboratively adjusting their structure and electrical configuration. For example, in MIMO mode, the terminal device reduces the number of grounding points for multiple antennas and optimizes the feed point locations, thereby effectively reducing the correlation between multiple antennas. In TXD mode, the terminal device increases the number of grounding points for multiple antennas and adjusts the feed phases of multiple antennas to enhance consistency between them, thereby improving signal coverage.

[0109] The embodiments of this application realize the dynamic adjustment of antenna structure or electrical parameters through antenna reconfigurable devices, enabling the antenna to flexibly adapt to different communication states and environmental conditions, improving data transmission efficiency and signal coverage, while enhancing the overall communication quality and stability of the terminal in complex wireless environments.

[0110] In some embodiments, the terminal includes a modem. The modem can be a hardware module within the terminal for processing communication signals, capable of receiving and parsing downlink signal information from a base station. The modem is not only responsible for data encoding / decoding and transmission, but also has the ability to read downlink signal strength, thereby providing data support for signal strength comparison. The downlink signal strength of each antenna in the terminal can be obtained in real time through the modem, reflecting the current network signal quality received by each antenna.

[0111] Correspondingly, the signal control method provided in this application embodiment may further include steps S41 and S42:

[0112] Step S41: Obtain the downlink signal strength of each antenna in the multi-antenna system based on the modem.

[0113] Downlink signal strength can be obtained through a modem, enabling dynamic monitoring of the status of multiple antennas and providing a basis for determining whether to enable or disable TXD, thereby optimizing power consumption.

[0114] Step S42: Determine the signal strength difference between the multiple antennas based on the downlink signal strength of each antenna.

[0115] Calculating the signal strength difference can assess the signal consistency between multiple antennas. When the signal strength difference exceeds a preset threshold, it indicates a high signal imbalance between the two antennas. If the signal strength difference exceeds this threshold, enabling TXD (Transient Voltage Discharge) may not significantly improve performance and could increase power consumption. Therefore, disabling TXD based on the signal strength difference can effectively reduce unnecessary power amplifier activation, thereby lowering overall terminal power consumption.

[0116] This application embodiment obtains the downlink signal strength of each antenna through a modem, providing reliable data support for subsequent antenna configuration adjustments and data transmission decisions. For example, it determines whether to turn off TXD, which can reduce the need for high power consumption operation when multiple antenna signals are unbalanced, thereby reducing terminal power consumption, extending battery life, and improving user experience.

[0117] The following will describe an exemplary application of the embodiments of this application in a real-world application scenario.

[0118] When related technologies simultaneously implement UL-MIMO or UL TXD on fixed dual antennas, they do not consider the mutual constraints between UL-MIMO, ULTXD, UL-SISO, and optimal operating power consumption. As a result, all technical services can only be run at a compromise performance level. Due to the lack of optimized design, both performance and user experience need to be improved.

[0119] When a user needs UL-MIMO for high UL speeds or TXD for signal enhancement, the transceiver will send multiple communication signals to the corresponding antennas to achieve simultaneous uplink from multiple antennas.

[0120] The related technologies also fail to consider the impact of antenna radiation gain imbalance. When the signal strength of both antennas reaches a certain level, the effect of both transmissions on TXD becomes very small. However, even with such a small effect on TXD, the power amplifiers corresponding to both transmitted signals are still turned on simultaneously, causing the power consumption of the transmission link to increase exponentially. Here, power consumption mainly refers to the power consumption of the PA (Power Amplifier).

[0121] To address the problems existing in related technologies, this application provides a technique for switching between high ECC and low imbalance in antennas, achieving reasonable adjustments between UL-MIMO, uplink TXD, and UL-SISO. Under strong signal conditions, the antenna is switched to a scheme with low ECC relative to the uplink antennas to achieve maximum throughput. Under weak signal conditions, it switches to a scheme with high ECC, and the imbalance between antennas is used to control the UL to make the optimal choice between increasing network coverage with dual-transmission and reducing power consumption with single-transmission.

[0122] ECC, or antenna correlation, is a crucial parameter for terminal antenna performance, and its magnitude is a key indicator of MIMO performance. TXD technology is used for antenna signal enhancement; in this case, ECC performance has a relatively small impact on the antenna. Moreover, when antenna multipath effects are not significant, stronger antenna correlation is actually preferable. Antenna ECC performance is primarily related to the antenna's radiation direction. The more similar the radiation directions, the closer the ECC value is to 1, indicating a stronger correlation. Better pattern complementarity (such as orthogonal polarization or coverage of different spatial regions) results in an ECC value approaching 0, indicating stronger independence.

[0123] Figure 4 This is a flowchart illustrating the antenna state switching process provided in this application embodiment. During terminal communication, antenna state switching can be achieved through steps S401 to S407:

[0124] Step S401: Determine whether the current frequency band supports multiple antennas.

[0125] During wireless communication, the terminal can determine whether the frequency band currently in use allows or supports the use of multi-antenna technology (such as MIMO or TXD) for data transmission.

[0126] Step S402: Obtain the current operating status of the multi-antenna system.

[0127] Step S403: Determine if MIMO is working.

[0128] Here, step S404 is executed if MIMO is working, and step S405 is executed if MIMO is not working.

[0129] Step S404: Switch antenna ECC performance priority.

[0130] In MIMO technology, each antenna transmits different data, which needs to be synthesized together within the terminal. The lower the correlation between the antennas, the easier it is to avoid interference during data demodulation. Therefore, when MIMO is working, the ECC performance of the switching antennas takes priority, even if the signal correlation between multiple antennas is less than a first threshold.

[0131] Step S405: Are the main and secondary antennas working?

[0132] If MIMO is not working, determine whether the main antenna and the secondary antenna are working. If the main antenna and the secondary antenna are working, proceed to step S406; if the main antenna and the secondary antenna are not working, the terminal continues to work in the current state.

[0133] Step S406: Determine whether the signal strength difference between the main and secondary antennas is greater than the strength threshold.

[0134] Step S407: Switch antenna to low ECC performance.

[0135] When the antenna is in transmit diversity mode, the data transmitted by the antennas is the same. Multiple antennas are used to enhance the signal. If the signal strength difference between the antennas is small, the contribution of the antenna synthesized signal will be small. At this time, the antennas can be switched to a state with a larger ECC to increase the radiation similarity of the antennas, thereby improving the antenna's scalability.

[0136] This application provides another embodiment that introduces an antenna imbalance mechanism to optimize TXD power consumption without significantly affecting UL performance, thereby solving the problem of high power consumption in UL when antenna conditions do not meet the requirements for improving UL performance.

[0137] The following explanation uses two transmitting antennas (2-TX) as an example. Figure 5 This is an architecture diagram of the communication system supporting uplink TXD in an embodiment of this application. The communication system (which may be a terminal) includes at least a modem 501, a transceiver 502, a signal amplifier 503, a transmit / receive front-end module 504, and an antenna 505. When the terminal needs TXD due to signal enhancement requirements, the transceiver 502 will send two communication signals, which will reach antenna 1 and antenna 2 respectively. At the same time, antenna 1 and antenna 2 are also receiving signals.

[0138] In this embodiment of the application, if the signal strength difference is still greater than 4dB even after the ECC has been adjusted to be greater than the second threshold, the power consumption of TXD is optimized. Figure 6This is a schematic flowchart of the diversity transmission optimization provided in the embodiments of this application. The diversity transmission optimization method can be implemented through steps S601 to S607:

[0139] S601, the current frequency band supports multiple antennas.

[0140] When the frequency band or standard in which the terminal operates supports uplink multi-antenna transmission, it can determine whether the downlink signal strength difference between the current antennas (the imbalance between antennas can be determined by judging the received signal strength) is greater than a threshold (i.e., a strength threshold used to judge the imbalance between antennas), such as the one mentioned above. Figure 3 This means that when the difference in antenna signal strength is greater than 4dB, the effect of TXD is already very small, and TXD can be turned off at this point.

[0141] Here, the TXD can be implemented by the terminal receiving a request to open the TXD, converting the request into a control signal in the communication processing section, and then sending the control signal to the transmission link to open the corresponding device on the link, such as a transceiver, PA, switch, etc.

[0142] S602. Obtain the received signal strength of the antenna where TXD is located.

[0143] Antenna signal strength can be obtained through Figure 5 Real-time reading of the Modem 501. When the signal strength difference meets the preset requirements (i.e., greater than the strength threshold), TXD support can be disabled on the Modem (after disabling TXD, the Modem only uses a single antenna to transmit data). If it is currently operating in UL-MIMO mode, it will not be affected.

[0144] UL-MIMO is primarily designed to increase throughput, so it is more suitable for strong signal conditions; while TXD is designed to enhance the transmission signal and is generally not needed under strong signal conditions, but if network scheduling is also enabled, the same shutdown scheme is also suitable.

[0145] UL-MIMO and UL TXD typically operate simultaneously on the same frequency band (meaning they can be switched). The specific mode of operation (UL-MIMO or UL TXD) can be configured based on network requirements and terminal support capabilities. This application assesses performance and power consumption by considering both terminal support and network signal conditions.

[0146] S603, Determine if the signal strength difference is less than the strength threshold.

[0147] In some embodiments, the strength threshold may be 4dB. When the signal strength difference is less than the strength threshold, step S604 is executed; when the signal strength difference is greater than or equal to the strength threshold, step S606 is executed.

[0148] S604, TXD is allowed.

[0149] S605, Waiting for network scheduling or opening TXD.

[0150] TXD (Telematics Disk Activation) can be enabled by network scheduling or by the terminal itself reporting its support capability. After TXD is permitted, it can be enabled automatically or wait for network-side scheduling to activate it. Some operators may control this from the base station side, with network scheduling waiting for the base station to issue a request to enable TXD.

[0151] Are S606 and TXD working?

[0152] In some embodiments, step S607 is executed when the TXD is working; if the TXD is not working, the terminal continues to work in its current state.

[0153] S607, Turn off TXD.

[0154] Disabling TXD can shut down the transmission channel containing the low-signal path. When the signal strength exceeds a threshold, the system determines whether TXD is active by checking if both antennas are working. If so, the transmission channel containing the low-signal path can be shut down. Disabling TXD support means the modem stops transmitting data signals through that channel.

[0155] Disabling TXD support on a modem can be achieved by sending a signal to stop the transmit channel containing the low-signal path of the transceiver. Simultaneously, the modem or transceiver sends a power-off signal to the PA (Power Amplifier) ​​via the General-Purpose Input / Output (GPIO) bus or the Mobile Industry Processor Interface (MIPI) bus, thus saving power. When the modem detects the need to disable the PA, it sends a shutdown command to the PA's register via the MIPI bus. The PA's internal logic interprets the command and shuts down the RF link.

[0156] In this embodiment, the downlink signal strength can be obtained by connecting the terminal to the base station simulator (call box); the triggering relationship between the uplink and downlink signals can also be detected by power detection instruments such as power meters and spectrum analyzers.
