[0028] To facilitate understanding, the background technology involved in this application is first introduced.

[0029] With the popularization of mobile services, roaming services and smart terminals and the development of power control, the popularity of dual-card or multi-card communication devices has increased, and users have put forward higher requirements for the communication performance and stability of multi-card services. In current technologies, the network configures the minimum transmission power of multiple cards of communication devices based on the measurement of communication devices to ensure that the communication devices can access the corresponding network normally and realize the stable operation of multi-card services.

[0030] However, different communication cards in a communication device that supports multiple cards share the same hardware resources and are limited by the maximum transmission power supported by the communication device. When the sum of the transmission powers of multiple communication cards is greater than the maximum transmission power supported by the communication device, the network will actively disconnect some of the communication card services to ensure the access performance of other communication cards. At the same time, the stability of multi-card services is poor.

[0031] Therefore, in order to solve the problems existing in the related technology, the present disclosure proposes a power control method, which reduces the channel quality indication (Channel Quality Indication, CQI) by comparing the priorities of multiple communication card services and counting the bit error rates of multiple communication cards, thereby realizing dynamic adjustment of the transmission power of each communication card and improving the multi-card transmission performance and communication stability.

[0032] Before introducing the detailed solution of the present disclosure, the scenario to which the solution of the present disclosure is applied is described first.

[0033] In some optional embodiments, the communication device supporting multiple communication cards may be a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or at least one of a wireless terminal device in a smart home, but not limited to these.

[0034] In some embodiments, the terms "terminal", "terminal device", "user equipment (UE)", "user terminal" "mobile station (MS)", "mobile terminal (MT)", subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, client and the like can be used interchangeably.

[0035] It can be understood that the description of the embodiments of the present disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the power control method, device and storage medium proposed in the embodiments of the present disclosure. A person of ordinary skill in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solutions proposed in the embodiments of the present disclosure are also applicable to similar technical problems.

[0036] Figure 1 A flow chart of a power control method provided by an embodiment of the present disclosure is as follows: Figure 1 As shown, the power control method includes steps 101-103.

[0037] Step 101, determining a first transmission power of a first communication card and a second transmission power of a second communication card.

[0038] In some embodiments of the present disclosure, the communication device determines a first transmission power of a first communication card and a second transmission power of a second communication card to determine whether they meet a first preset condition.

[0039] In some embodiments of the present disclosure, there is no limitation on the type of communication device executing the method, which may be, for example, a terminal, a baseband chip, etc.

[0040] In some embodiments of the present disclosure, the communication device supports at least two communication cards, that is, the communication device can adjust the transmission power of more than or equal to two communication cards.

[0041] In some embodiments of the present disclosure, there is no restriction on the type of communication card, that is, there is no restriction on the types of the first communication card and the second communication card, which may be, for example, a SIM card, a removable user identity module (Removable User Identity Module, R-UIM) card, a user identification module (User Identifier Module, UIM) card and a universal subscriber identity module (Universal Subscriber Identity Module, USIM) card, etc., wherein the types of the first communication card and the second communication card may be the same or different.

[0042] In some embodiments of the present disclosure, the first transmission power is an initial transmission power corresponding to a first communication service of the first communication card, and the second transmission power is an initial transmission power corresponding to a second communication service of the second communication card.

[0043] In some embodiments of the present disclosure, the initial transmission power may be the first transmission power and / or the second transmission power without transmission power adjustment, or the third transmission power and / or the fourth transmission power obtained after transmission power adjustment, which is not limited by the present disclosure. In other words, the initial transmission power may be the transmission power of the communication card before each transmission power adjustment.

[0044] In some embodiments of the present disclosure, there is no restriction on the names of the first transmit power and the second transmit power, which may be, for example, “initial transmit power”, “original transmit power”, etc.

[0045] Step 102: When the first transmission power and the second transmission power satisfy a first preset condition, determine the levels of the first communication service and the second communication service.

[0046] In some embodiments of the present disclosure, the first transmit power and the second transmit power satisfy a first preset condition, and the communication device may determine the level of the first communication service and the second communication service to adjust the first transmit power and / or the second transmit power according to the level.

[0047] In some embodiments of the present disclosure, the first preset condition may be that the sum of the first transmit power and the second transmit power is greater than the maximum transmit power supported by the communication device, that is, only the first transmit power is greater than the maximum transmit power supported by the communication device. In other words, when the sum of the first transmit power and the second transmit power is greater than the maximum transmit power supported by the communication device, the communication device can determine the level of the first communication service and the second communication service.

[0048] In some embodiments of the present disclosure, the level of the communication service may be a priority level preset according to the purpose of the communication service, or may be a priority level preset according to the size of the resources occupied by the communication service, and the present disclosure does not limit this. For example, based on different real-time requirements, a low-priority service may be a packet switching (PS) domain service, such as a streaming media service in the PS domain, and a high-priority service may be a circuit switching (CS) domain service, such as a voice service, wherein the communication service level of the voice service is higher than the streaming media service level of the packet switching service.

[0049] Step 103: adjust the first transmission power and / or the second transmission power based on the levels of the first communication service and the second communication service.

[0050] In some embodiments of the present disclosure, the communication device adjusts the first transmission power and / or the second transmission power based on the levels of the first communication service and the second communication service to achieve dynamic adjustment of the transmission power of the communication card.

[0051] In some embodiments of the present disclosure, the first communication service and the second communication service have different levels, and the communication quality of the high-level communication service is prioritized. The communication equipment can reduce the transmission power of the communication card with the low communication service level, so that the sum of the adjusted transmission powers of the communication cards is less than or equal to the maximum transmission power supported by the communication equipment, thereby realizing the simultaneous and stable operation of multiple communication card services.

[0052] In some embodiments of the present disclosure, the first communication service and the second communication service are of the same level, and the communication device can adjust the first transmission power and / or the second transmission power through relevant parameters so that the sum of the adjusted transmission powers of the communication cards is less than or equal to the maximum transmission power supported by the communication device, thereby achieving stable simultaneous operation of multiple communication card services.

[0053] In summary, according to the power control method proposed in the present disclosure, the method includes: determining the first transmission power of the first communication card and the second transmission power of the second communication card, the first transmission power is the initial transmission power corresponding to the first communication service of the first communication card, and the second transmission power is the initial transmission power corresponding to the second communication service of the second communication card; when the first transmission power and the second transmission power meet the first preset condition, determining the level of the first communication service and the second communication service; based on the level of the first communication service and the second communication service, adjusting the first transmission power and / or the second transmission power. This method determines the communication service level of multiple communication cards and sets the corresponding power adjustment scheme, so that the sum of the adjusted transmission powers of the multiple communication cards is less than or equal to the maximum transmission power supported by the communication device, thereby realizing dynamic adjustment of the transmission power of each communication card and improving the multi-card transmission performance and communication stability.

[0054] Figure 2 A schematic diagram of a power control method according to an embodiment of the present disclosure is shown in FIG. Figure 2 As shown, in Figure 1 Based on the illustrated embodiment, step 101 is further explained, and the power control method includes steps 201-204.

[0055] Step 201, determine the size of the data packet to be sent.

[0056] In some embodiments of the present disclosure, the communication device may determine the size of a data packet to be used for communication services, laying a foundation for determining the first path loss and the second path loss.

[0057] In some embodiments of the present disclosure, the data packet to be sent may include a transmission rate when performing a communication service, but is not limited thereto, and may also be other data. The size of the data packet to be sent is positively correlated with the size of the first transmission power and the second transmission power, that is, when the data packet to be sent is larger, the first transmission power or the second transmission power is larger; when the data packet to be sent is smaller, the first transmission power or the second transmission power is smaller.

[0058] In some embodiments of the present disclosure, the communication device may determine the size of the data packet to be sent by the interval between characters, or may determine the size of the data packet to be sent by other means, which is not limited by the present disclosure.

[0059] Step 202: Determine first parameters of the first communication card and the second communication card.

[0060] In some embodiments of the present disclosure, the communication device may determine first parameters of the first communication card and the second communication card, laying a foundation for determining the first transmission power and / or the second transmission power.

[0061] In some embodiments of the present disclosure, the first parameter may be a reference signal receiving power (RSRP).

[0062] Specifically, in some embodiments, the communication device may receive a reference signal sent by a network device and determine the received power of the reference signal. The present disclosure does not limit the form of the reference signal, which may be, for example, a reference signal such as a "Channel State Information Reference Signal (CSI-RS)"; the present disclosure does not limit the method for determining the received power of the reference signal, which may be, for example, a communication device determining the received power of the reference signal through a power setting algorithm.

[0063] Step 203: Determine a first path loss of the first communication card and a second path loss of the second communication card based on the first parameter and the second parameter sent by the network device.

[0064] In some embodiments of the present disclosure, the communication device can determine the first path loss of the first communication card and the second path loss of the second communication card based on the first parameter and the second parameter sent by the network device, laying the foundation for determining the first transmission power and / or the second transmission power.

[0065] In some embodiments of the present disclosure, the second parameter may be the transmit power of a reference signal.

[0066] In some embodiments of the present disclosure, the communication device may receive a first signaling to receive a second parameter sent by a network device. The first signaling may be, for example, a radio resource control (RRC) signaling, but is not limited thereto and may also be other signaling.

[0067] Specifically, in some embodiments of the present disclosure, the communication device may determine the first path loss of the first communication card and the second path loss of the second communication card by subtracting the first parameter from the second parameter.

[0068] In some embodiments of the present disclosure, since the network devices that perform services with the communication card of the communication device may be different, the first path loss and the second path loss may be different.

[0069] Step 204: Determine the first transmission power and / or the second transmission power based on the first path loss and the second path loss and the size of the data packet to be transmitted.

[0070] In some embodiments of the present disclosure, the communication device determines the first transmission power and / or the second transmission power based on the first path loss and the second path loss and the size of the data packet to be sent to determine whether the first preset condition is met.

[0071] In some embodiments of the present disclosure, the method of determining the first transmission power and / or the second transmission power is not limited, and any method of determining the transmission power using path loss and the size of the data packet to be transmitted falls within the scope of the present disclosure.

[0072] In summary, according to the power control method proposed in the present disclosure, the method includes: determining the size of the data packet to be sent; determining the first parameters of the first communication card and the second communication card; determining the first path loss of the first communication card and the second path loss of the second communication card based on the first parameter and the second parameter sent by the network device; determining the first transmission power and / or the second transmission power based on the first path loss and the second path loss and the size of the data packet to be sent. The method determines the first transmission power and / or the second transmission power by determining the size of the data packet to be sent, the first parameter and the second parameter.

[0073] Figure 3 A schematic diagram of a power control method according to an embodiment of the present disclosure is shown in FIG. Figure 3 As shown, in Figure 1 Based on the illustrated embodiment, step 103 is further explained, and the power control method includes steps 301-303.

[0074] Step 301: determine that the level of a first communication service is a first level, determine that the level of a second communication service is a second level, and the first level is lower than the second level.

[0075] In some embodiments of the present disclosure, the communication device may determine the level of the first communication service as the first level, and determine the level of the second communication service as the second level, where the first level is lower than the second level, and adjust the communication card transmission power according to the communication service level.

[0076] In some embodiments of the present disclosure, the communication service level may be preset, for example, the first level may be a packet switching (PS) service, and the second level may be a voice service, wherein the communication service level of the voice service is higher than the communication service level of the packet switching service.

[0077] Step 302: adjust the channel quality indication CQI reporting mechanism of the first communication card, and adjust the first transmission power of the first communication card to a third transmission power based on the adjusted CQI reporting mechanism, wherein the third transmission power is lower than the first transmission power.

[0078] In some embodiments of the present disclosure, the communication device can adjust the channel quality indication CQI reporting mechanism of the first communication card, and adjust the first transmission power of the first communication card to a third transmission power based on the adjusted CQI reporting mechanism, wherein the third transmission power is lower than the first transmission power, so as to reduce the transmission power of communication services with low communication service levels, and give priority to ensuring the communication service quality of communication cards with high communication service levels.

[0079] Specifically, the communication device can adjust the CQI reporting mechanism of the first communication card, that is, reduce the CQI value sent by the first communication card to the network, reduce the transmission block size (Transport Block Size, TB Size) and modulation and coding strategy (Modulation and Coding Scheme, MCS) of the first communication card, thereby reducing the first transmission power of the first communication card to the third transmission power.

[0080] Step 303, when the second transmit power meets the second preset condition, adjust the CQI reporting mechanism of the second communication card, and adjust the second transmit power of the second communication card to a fourth transmit power based on the adjusted CQI reporting mechanism, where the fourth transmit power is lower than the second transmit power.

[0081] In some embodiments of the present disclosure, when the second transmission power meets the second preset condition, the communication device adjusts the CQI reporting mechanism of the second communication card, and adjusts the second transmission power of the second communication card to a fourth transmission power based on the adjusted CQI reporting mechanism. The fourth transmission power is lower than the second transmission power, so as to realize dynamic adjustment of the transmission power of each communication card and improve the multi-card transmission performance and communication stability.

[0082] In some embodiments of the present disclosure, the second preset condition may be that the second transmission power is greater than the maximum power supported by the communication device. When only the second transmission power is greater than the maximum transmission power supported by the communication device, the communication device reduces the second transmission power to provide support resources for the first communication service, ensuring that multi-card communication services can be performed simultaneously.

[0083] Specifically, the communication device can adjust the CQI reporting mechanism of the second communication card, that is, reduce the CQI value sent by the second communication card to the network, reduce the transmission block size and modulation and coding strategy of the second communication card, thereby reducing the second transmission power of the second communication card to the fourth transmission power.

[0084] In some embodiments of the present disclosure, step 303 is optional, and the communication device may determine whether to execute this step according to the application scenario.

[0085] In summary, according to the power control method proposed in the present disclosure, the method includes: determining that the level of the first communication service is the first level, determining that the level of the second communication service is the second level, and the first level is lower than the second level; adjusting the CQI reporting mechanism of the first communication card, and adjusting the first transmission power of the first communication card to the third transmission power based on the adjusted CQI reporting mechanism, and the third transmission power is lower than the first transmission power; when the second transmission power meets the second preset condition, adjusting the CQI reporting mechanism of the second communication card, and adjusting the second transmission power of the second communication card to the fourth transmission power based on the adjusted CQI reporting mechanism, and the fourth transmission power is lower than the second transmission power. This method improves the transmission performance and communication stability of multiple cards by dynamically adjusting the CQI reporting mechanism of the first communication card and / or the second communication card according to the second preset condition when the communication service levels of multiple cards are different, and adjusting the first transmission power and / or the second transmission power based on the adjusted CQI reporting mechanism.

[0086] Figure 4 A schematic diagram of a power control method according to an embodiment of the present disclosure is shown in FIG. Figure 4 As shown, in Figure 1 Based on the illustrated embodiment, step 103 is further explained. The power control method includes step 401 and step 402 .

[0087] Step 401: When the levels of the first communication service and the second communication service are the same, a first bit error rate of the first communication card and / or a second bit error rate of the second communication card are counted.

[0088] In some embodiments of the present disclosure, when the levels of the first communication service and the second communication service are the same, the first communication card and / or the second communication card can count the first bit error rate of the first communication card and / or the second bit error rate of the second communication card to adjust the first transmission power and / or the second transmission power, but not limited to this. The present disclosure does not limit the execution subject of counting the first bit error rate of the first communication card and / or the second bit error rate of the second communication card. When counting the first bit error rate of the first communication card and / or the second bit error rate of the second communication card, the communication card can count periodically or at a specified time point or time period, and this embodiment does not limit it.

[0089] In some embodiments of the present disclosure, when a communication card performs communication services, it sends data packets to a network device. The communication card can determine the transmission bit error rate of the communication card during the period by periodically counting the correct number and the error number of sent and received data packets, and send the bit error rate to the communication device.

[0090] Step 402: Based on the first bit error rate and / or the second bit error rate, adjust the first transmit power to a third transmit power and adjust the second transmit power to a fourth transmit power.

[0091] In some embodiments of the present disclosure, the communication device can adjust the first transmission power to the third transmission power and the second transmission power to the fourth transmission power based on the first bit error rate and / or the second bit error rate to ensure that multi-card services can be carried out simultaneously and improve multi-card transmission performance and communication stability.

[0092] The specific adjustment method can be found in the following embodiments and will not be described in detail here.

[0093] In summary, according to the power control method proposed in the present disclosure, the method includes: when the levels of the first communication service and the second communication service are the same, the first bit error rate of the first communication card and / or the second bit error rate of the second communication card are counted, and the first transmission power is adjusted to the third transmission power and the second transmission power is adjusted to the fourth transmission power. This method improves the transmission performance and communication stability of multiple cards by adjusting the first transmission power and / or the second transmission power based on the statistics of the first bit error rate of the first communication card and / or the second bit error rate of the second communication card when the communication service levels of multiple cards are the same.

[0094] Figure 5 A schematic diagram of a power control method according to an embodiment of the present disclosure is shown in FIG. Figure 5 As shown, in Figure 4 Based on the illustrated embodiment, step 402 is further explained, and the power control method includes steps 501-503.

[0095] Step 501: When the first bit error rate and / or the second bit error rate meets a third preset condition, a first maximum transmission power of the first communication card and a second maximum transmission power of the second communication card are determined based on the first transmission power and the second transmission power.

[0096] In some embodiments of the present disclosure, when the first bit error rate and / or the second bit error rate meets the third preset condition, the communication device can determine the first maximum transmission power of the first communication card and the second maximum transmission power of the second communication card based on the first transmission power and the third transmission power to determine the third transmission power and the fourth transmission power range.

[0097] In some embodiments of the present disclosure, the third preset condition may include that the first bit error rate and / or the second bit error rate are both less than a set bit error rate threshold; the first bit error rate is greater than the set bit error rate threshold, and the second bit error rate is less than the set bit error rate threshold, wherein the first bit error rate and the second bit error rate are only used to distinguish the bit error rates of communication cards performing different communication services. In some embodiments, the second bit error rate may be greater than the set bit error rate threshold, and the first bit error rate may be less than the set bit error rate threshold; and the first bit error rate and / or the second bit error rate are both greater than the set bit error rate threshold.

[0098] Specifically, in some embodiments, the first bit error rate and / or the second bit error rate are both less than the set bit error rate threshold, and the communication device may determine the first maximum transmission power of the first communication card by the following formula;

[0099]

[0100] Among them, Pmax_sim0 represents the first maximum transmission power of the first communication card, Pmax represents the maximum transmission power supported by the communication device, Pcurr_sim0 represents the first transmission power, and Pcurr_sim1 represents the second transmission power.

[0107] And determining the second maximum transmission power of the second communication card by the following formula;

[0108]

[0109] The definition of the parameters in the above formula can be referred to the relevant explanation of formula 1.3, which will not be repeated here.

[0110] Specifically, in some embodiments, the first bit error rate and / or the second bit error rate are both greater than the set bit error rate threshold. The communication device can determine the first maximum transmission power of the first communication card through the above formula 1.1, and determine the second maximum transmission power of the second communication card through the above formula 1.2. Please refer to the relevant embodiments and will not be repeated here.

[0111] Step 502: adjust the CQI reporting mechanism of the first communication card, and adjust the first transmit power to a third transmit power based on the adjusted CQI reporting mechanism, where the third transmit power is less than or equal to the first maximum transmit power.

[0112] In some embodiments of the present disclosure, the communication device can adjust the CQI reporting mechanism of the first communication card, and adjust the first transmission power to a third transmission power based on the adjusted CQI reporting mechanism, where the third transmission power is less than or equal to the first maximum transmission power, so that the communication device can maintain multi-card communication services and improve multi-card transmission performance and communication stability.

[0113] Specifically, the communication device can adjust the CQI reporting mechanism of the first communication card, that is, reduce the CQI value sent by the first communication card to the network, reduce the transmission block size and modulation and coding strategy of the first communication card, thereby reducing the first transmission power of the first communication card to a third transmission power, which is less than or equal to the first maximum transmission power.

[0114] Step 503: adjust the CQI reporting mechanism of the second communication card, and adjust the second transmit power to a fourth transmit power based on the adjusted CQI reporting mechanism, where the fourth transmit power is less than or equal to the second maximum transmit power.

[0115] In some embodiments of the present disclosure, the communication device can adjust the CQI reporting mechanism of the second communication card, and adjust the second transmit power to a fourth transmit power based on the adjusted CQI reporting mechanism, where the fourth transmit power is less than or equal to the second maximum transmit power, so that the communication device can maintain multi-card communication services and improve multi-card transmission performance and communication stability.

[0116] Specifically, the communication device can adjust the CQI reporting mechanism of the second communication card, that is, reduce the CQI value sent by the second communication card to the network, reduce the transmission block size and modulation and coding strategy of the second communication card, thereby reducing the second transmission power of the second communication card to the fourth transmission power, which is less than or equal to the second maximum transmission power.

[0117] In summary, according to the power control method proposed in the present disclosure, the method includes: when the first bit error rate and / or the second bit error rate meet the third preset condition, based on the first transmission power and the second transmission power, determine the first maximum transmission power of the first communication card and the second maximum transmission power of the second communication card; adjust the CQI reporting mechanism of the first communication card, and adjust the first transmission power to the third transmission power based on the adjusted CQI reporting mechanism, and the third transmission power is less than or equal to the first maximum transmission power; adjust the CQI reporting mechanism of the second communication card, and adjust the second transmission power to the fourth transmission power based on the adjusted CQI reporting mechanism, and the fourth transmission power is less than or equal to the second maximum transmission power. This method determines the first maximum transmission power of the first communication card and the second maximum transmission power of the second communication card, adjusts the CQI reporting mechanism of the first communication card and / or the second communication card, and adjusts the first transmission power and the second transmission power to the third transmission power and the fourth transmission power based on the adjusted CQI reporting mechanism, so that the first transmission power is less than or equal to the first maximum transmission power, and the second transmission power is less than or equal to the second maximum transmission power, so as to ensure that multi-card communication services are carried out simultaneously, and improve multi-card transmission performance and communication stability.

[0118] This solution determines the communication service levels of multiple communication cards, proposes corresponding power control methods for the same service level and different service levels, and adjusts the transmission power of one or more communication cards to ensure that multi-card communication services are carried out simultaneously. This solves the problem that when the sum of the transmission powers of multiple communication cards is greater than the maximum transmission power supported by the communication equipment, the network will actively disconnect some of the communication card services, causing the communication services of some communication cards to be interrupted. At the same time, it improves the multi-card transmission performance and communication stability.

[0119] Therefore, this solution has the following beneficial effects:

[0120] 1. This solution determines the communication service level of the communication card. When the communication service levels of the communication cards are different, the transmission power of the communication card with a lower communication service level is reduced to ensure the quality of the high-level communication service. At the same time, it ensures that the communication services of multiple cards can be carried out simultaneously, thereby improving the multi-card transmission performance and communication stability.

[0121] 2. This solution determines the communication service level of the communication card. When the communication service levels of the communication cards are the same, it determines the maximum transmission power of each communication card, reduces the CQI value sent to the network, and adjusts the transmission power of the communication card to make it less than or equal to the determined maximum transmission power, thereby ensuring that multi-card communication services can be carried out simultaneously and improving multi-card transmission performance and communication stability.
