Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.

Many communication protocols or communication standards that can be supported by electronic devices, such as cell phones, such as networks based on the mobility specifications of 3GPP (3 rd Generation Partnership Project), include: NR (new radio) communication network, LTE (long term Evolution ) network, LTE-FDD (frequency Division duplex, LTE frequency Division duplex) network, TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, time Division synchronous code Division multiple access) network, WCDMA (Wideband Code Division Multiple Access ) network, EVDO (Evolution-Data Optimized) network, CDMA2000 (Code Division Multiple Access ) network, GSM (Global System for Mobile Communications, global system for mobile communications) network, and the like.

With the development of 5G wireless communication technology, more and more electronic devices support 5G technology. In the process of applying the 5G technology, the network construction scale is gradually enlarged, and corresponding tasks of network maintenance, network planning and network optimization are increasingly heavy. Similar to cellular communication technologies, the allocation and optimization tasks of neighboring cells under 5G technology are increasingly heavier.

The 5G-enabled electronic devices are typically NSA (non-independent networking) based on ENDC (new radio-dual connectivity). The NSA network can make up the defect of too slow 5G networking, and meanwhile, the 4G base station can play a great role in the 5G era. In addition, the NSA non-independent networking technology relies on the existing 4G base station, so that operators can rapidly complete 5G network laying, and the NSA non-independent networking technology is low in construction cost. The 5G technology is different from the 4G technology, and the communication signal frequency band in the 5G technology is high and the attenuation is fast, so that the number of base stations is more, and the construction period also becomes long. The NSA may play a role in transition between 4G and 5G, and when the electronic device detects that the NR signal value meets the B1 or B2 threshold, i.e. the threshold for starting the handover of the different system, during the LTE camping, the NSA connection may be configured.

In addition, in order to meet the use requirements of users, multi-card electronic devices are widely used, and the multi-card electronic devices can support services of at least one operator. For a base station, a multi-card electronic device, such as a dual-card electronic device, is equivalent to two electronic devices. The maximum transmit power of a single SIM card (Subscriber Identity Module, subscriber identity card) in a two-card electronic device is half that of a single card electronic device, as compared to a single card electronic device. In the related art, the communication frequency band of the 4G or 5G communication network is high and the bandwidth is large, and the power consumption is large for the multi-card electronic device. On the basis of the reduction of the maximum transmitting power, the coverage signal of the base station signal to the multi-card electronic equipment is weak, and the user experience is affected.

In the related art, the reasons for the weak coverage signal of the base station signal to the multi-card electronic device may include:

first, in a multi-card electronic device such as a dual-card electronic device, the maximum transmission power of a single SIM card becomes smaller. Compared with single-card electronic equipment, the coverage distance of the base station signal to the double-card electronic equipment is reduced by about 1/3, the coverage range of the base station signal is reduced, and the base station coverage signal is weakened on the basis that the maximum transmitting power is reduced.

Secondly, for a signal coverage area with larger link loss, in combination with the use habit of the multi-card electronic equipment and the coverage intensity of base station signals, uplink limitation easily occurs in communication between the multi-card electronic equipment and the base station in various use scenes.

For example, when used indoors, indoor signal coverage is weaker than outdoor signal coverage, and uplink limitation occurs. Or, the outdoor is far away from suburban area of the base station configuration cell, the uplink of the user is limited when the cell covers the edge, and the communication signal is more affected when the maximum transmitting power is reduced.

For another example, in combination with the usage habits of the user, during most of the time, multiple SIM cards are not simultaneously operating, e.g., one card is operating and another card is in an IDLE state (IDLE); in this scenario, the maximum transmitting power of the working card is still only half of the maximum transmitting power, which affects the communication efficiency.

In order to solve the problems in the related art, the present disclosure proposes a method for determining a transmit power, which is applied to an electronic device, and the electronic device includes at least two SIM cards. The method comprises the following steps: and reporting the capability information to the base station, wherein the power parameter is the maximum transmitting power of the electronic equipment. And determining the communication state of the electronic equipment according to the service states of at least two SIM cards in the electronic equipment. And determining target transmitting power of the SIM card according to the communication state, wherein the target transmitting power is equal to or smaller than the maximum transmitting power of the electronic equipment. In the method disclosed by the invention, for the multi-card electronic equipment, when the electronic equipment reports the power parameter of each SIM card, the maximum transmitting power of the electronic equipment is reported. And combining the service state of the SIM card in the electronic equipment, and dynamically configuring the target transmitting power of the SIM card. Therefore, under the corresponding scene, the target transmitting power of the SIM card can reach the maximum transmitting power of the electronic equipment, the communication efficiency of the electronic equipment and the communication quality between the electronic equipment and the base station are improved, and the user experience is improved.

As shown in fig. 1, the method of the present disclosure may be used to optimize the communication quality of a wireless communication system. The wireless communication system 100 may include a multi-card electronic device 101 and a base station 102. Multi-card electronic device 101 may be in communicative interaction with base station 102.

In an exemplary embodiment, the method for determining the transmission power in the present embodiment is applied to an electronic device. Wherein the electronic device comprises at least two SIM cards. The electronic device may be, for example, a User Equipment (UE) such as a mobile phone, tablet, or internet of vehicles device.

As shown in fig. 2, the method of the present embodiment may include the steps of:

and S210, reporting the capability information to the base station.

S220, determining the communication state of the electronic equipment according to the service states of at least two SIM cards in the electronic equipment.

S230, determining target transmitting power of the SIM card according to the communication state.

In step S210, the capability information is used to indicate that the maximum transmission power of at least two SIM cards in the electronic device is the maximum transmission power of the electronic device. In this step, the processor sets the maximum transmit power PCMAX of each SIM as the maximum transmit power MTPL of the electronic device, and reports the maximum transmit power PCMAX to the base station. For example pcmax= mtpl= 26dBm.

This step may be performed in a primary communication interaction scenario of the electronic device with the base station. For example, when the electronic device is powered on or a service connection (such as making a call) is established, capability information, that is, capability (capability) of the UE, is reported to the base station. In this embodiment, when the UE capability is reported, a dynamic transmit power field (for example, dynamic powershare dualsim) is added to the UE capability to characterize the electronic device in the embodiment of the present disclosure, so as to dynamically adjust the power of the SIM card, and achieve that the maximum transmit power of at least two SIM cards reaches the maximum transmit power of the electronic device.

In step S220, the processor may determine a traffic state of each SIM card. The service status of the SIM card may for example include: an idle state or a connected state, and a full scheduling state and a non-full scheduling state may be further included in the connected state.

In this step, the processor may further determine a communication status of the electronic device according to different service statuses of the at least two SIM cards. The communication states include, for example: a single card communication state or a simultaneous communication state of at least two SIM cards. The traffic state of the SIM card or the communication state of the electronic device may reflect the link budget during the communication.

In step S230, the target transmit Power (PCMAX) may be equal to or less than the Maximum Transmit Power (MTPL) of the electronic device. The MTPL may be 26dBm. The processor can dynamically allocate the target transmitting power of different SIM cards according to different communication states of the SIM cards. After determining the target transmit power PCMAX of the SIM card, the processor may further perform uplink channel power control according to the target transmit power.

In this embodiment, different communication states are combined, and uplink transmission capability of the electronic device is utilized to the greatest extent, so that a work card in the multi-card device can use maximum transmission power of the electronic device to perform communication, and communication quality is improved.

In an exemplary embodiment, as shown in fig. 3, the present embodiment may include the following steps:

and S310, determining that the communication state is a first state in response to the fact that only the target SIM card in the at least two SIM cards is in a connection state and the at least two SIM cards except the target SIM card are in an idle state.

S320, in response to the communication state being the first state, determining that the target transmitting power of the target SIM card is: maximum transmit power of the electronic device.

In step S310, the processor may determine a service status of each SIM card, and record the current communication status as the first status when only the target SIM card is in the connected state and the rest cards are in the idle state.

In step S320, in the first state, the SIM cards except the target SIM card are in an idle state, and UL subframes (uplink information) between different SIM cards do not overlap at all. Thus, the processor may configure the target transmit power of the target SIM card to: maximum Transmit Power (MTPL) of an electronic device.

In this embodiment, a dual-card electronic device is taken as an example, and the following description is given in connection with the following example. The dual-card electronic device comprises a first SIM card and a second SIM card, wherein the first SIM card can be a main card, and the second SIM card can be a sub-card.

In one example, as shown in connection with fig. 6, the target SIM card is the first SIM card 10, and in a connected state, uplink information may be sent. The second SIM card 20 is in an idle state and does not transmit uplink information. The communication state is a first state.

The processor configures the target transmit Power (PCMAX) of the first SIM card 10 to be the Maximum Transmit Power (MTPL) of the electronic device. In this example pcmax= MTPL-MPR, where the processor sets mpr=0. MPR characterizes a back-off value of maximum transmit power, MPR parameters are allocated in the 3GPP protocol for the electronic device, and a processor of the electronic device may be adapted to set MPR. The MTPL may be 26dBm.

In another example, as shown in connection with fig. 7, the target SIM card is the second SIM card 20, and in a connected state, uplink information may be sent. The first SIM card 10 is in an idle state and does not transmit uplink information. The communication state is still the first state.

The processor configures the target transmit Power (PCMAX) of the second SIM card 20 to be the Maximum Transmit Power (MTPL) of the electronic device. In this example pcmax= MTPL-MPR, where the processor sets mpr=0. MPR characterizes a back-off value of maximum transmit power, MPR parameters are allocated in the 3GPP protocol for the electronic device, and a processor of the electronic device may be adapted to set MPR. The MTPL may be 26dBm.

In combination with the above two examples, in this embodiment, the target transmission power of the target SIM card reaches 26dBm, which is the maximum transmission power of the electronic device, instead of 23dBm, which is half the maximum transmission power in the related art. The uplink sending capability of the target SIM card is conveniently utilized to the maximum, so that the communication signals and the communication quality of the target SIM card and the base station are improved.

In this embodiment, after determining the target transmit Power (PCMAX), uplink power control may be performed according to the following manner, i.e., determining the uplink channel power P of the SIM card _PUSCH ：

Wherein P is _{O_PUSCH} (j) And characterizing the reference received power set by the base station.

Characterizing the number of RBs allocated to the electronic device (the smallest physical resource unit that the radio side data channel can schedule), μ represents the subcarrier spacing. Alpha (j) characterizes the path loss compensation factor, PL (q) _d ) And characterizing the downlink loss detected by the electronic equipment. Delta _TF (i) The power offset value is characterized. f (i, l) characterizes the uplink channel transmit power P _PUSCH Is used for adjusting the adjustment amount of the (a).

In an exemplary embodiment, as shown in fig. 4, step S220 in this embodiment may include the following steps:

s2201, in response to at least two SIM cards being in a connection state, determining the current transmitting power of the SIM cards in the connection state.

S2202, determining the communication state of the electronic equipment according to the current transmitting power of the SIM card in the connected state.

In step S2201, when more than one SIM card is in a connected state, it indicates that more than one SIM card is working, and there may be a situation that UL subframes partially overlap or completely overlap between SIM cards.

In this step, the processor may determine the current transmit power of each SIM, such as by a radio frequency management chip.

In step S2202, when more than one SIM card is in a connected state, the processor may determine a communication state of the electronic device according to a relationship of current transmission power of the connected SIM cards.

For example, taking an example that at least two SIM cards include a first SIM card and a second SIM card, and the first SIM card and the second SIM card are both in a connection state, step S2202 in this embodiment may include the following steps:

s2202-1, determining that the communication state is the second state in response to the sum of the current transmission power of the first SIM card and the current transmission power of the second SIM card being greater than the power threshold.

In this step, the power threshold may be, for example: maximum transmit power MTPL of the electronic device, or half MTPL/2 of the maximum transmit power. The MTPL may be 26dBm. The processor combines the current transmitting power P (SIM 1) of the first SIM card and the current transmitting power P (SIM 2) of the second SIM card to judge, and when the power threshold value of P (SIM 1) +P (SIM 2) > is defined as the communication state is the second state.

S2202-2, determining that the communication state is a third state in response to the sum of the current transmission power of the first SIM card and the current transmission power of the second SIM card being not greater than the power threshold.

In this step, the processor combines the current transmission power P (SIM 1) of the first SIM card and the current transmission power P (SIM 2) of the second SIM card to determine that the communication state is defined as the third state when P (SIM 1) +p (SIM 2) +..

In an exemplary embodiment, in conjunction with the embodiment corresponding to fig. 4, as shown in fig. 5, step S230 in this embodiment may include the following steps:

s2301, in response to the communication status being the second status, determining that the target transmit power of each SIM card is: half of the maximum transmit power of the electronic device.

S2302, in response to the communication status being the third status, determining that the target transmit power of each SIM card is: maximum transmit power of the electronic device.

In step S2301, when the processor determines that the communication status is the second status, it indicates that both SIM cards are in the connected status, where at least one SIM card is in the full-schedule status, in connection with the corresponding embodiment of fig. 4. Thus, the processor may configure the target transmit power PCMAX for each SIM to: half of maximum transmit power, MTPL/2. For example, the MTPL may be 26dBm, with the target transmit power PCMAX for each SIM set to 23dBm.

In this step, the processor may set mpr=3 dB to configure the target transmit power of each SIM card to MTPL/2.

To further describe the scenario to which this step corresponds, the following list a few examples.

In a first example, as shown in fig. 8, the first SIM card 10 is in an FDD (frequency division duplex) connected state and is not fully scheduled, and the second SIM card 20 is in an FDD connected state and is fully scheduled. At this time, the processor may simultaneously configure the target transmit powers PCMAX of the first SIM card 10 and the second SIM card 20 to be: half of maximum transmit power, MTPL/2. For example, the MTPL may be 26dBm, with the target transmit power PCMAX for each SIM set to 23dBm.

In a second example, shown in fig. 9, the first SIM card 10 is in an FDD (frequency division duplex) connected state and fully scheduled, and the second SIM card 20 is in an FDD connected state and not fully scheduled. At this time, the processor may simultaneously configure the target transmit powers PCMAX of the first SIM card 10 and the second SIM card 20 to be: half of maximum transmit power, MTPL/2. For example, the MTPL may be 26dBm, with the target transmit power PCMAX for each SIM set to 23dBm.

In a third example, as shown in fig. 10, the first SIM card 10 is in a TDD (time division duplex) connected state and is not fully scheduled, and the second SIM card 20 is in a TDD connected state and is fully scheduled. At this time, the processor may simultaneously configure the target transmit powers PCMAX of the first SIM card 10 and the second SIM card 20 to be: half of maximum transmit power, MTPL/2. For example, the MTPL may be 26dBm, with the target transmit power PCMAX for each SIM set to 23dBm.

In a fourth example, as shown in fig. 11, the first SIM card 10 is in a TDD (time division duplex) connected state and fully scheduled, and the second SIM card 20 is in a TDD connected state and not fully scheduled. At this time, the processor may simultaneously configure the target transmit powers PCMAX of the first SIM card 10 and the second SIM card 20 to be: half of maximum transmit power, MTPL/2. For example, the MTPL may be 26dBm, with the target transmit power PCMAX for each SIM set to 23dBm.

In step S2302, in conjunction with the embodiment corresponding to fig. 4, when the processor determines that the communication state is the third state, it indicates that both SIM cards are in a connected state, but in a non-full schedule state. Thus, the processor may control the target transmit power PCMAX for each SIM card to be: the maximum transmit power MTPL is, for example, 26dBm.

In this step, the processor may set mpr=0 to achieve the goal of configuring the target transmit power of each SIM card to MTPL in combination with pcmax= MTPL-MPR.

To further describe the scenario corresponding to this step, the following lists several examples.

In a first example, as shown in fig. 12, the first SIM card 10 is in FDD connected state and not fully scheduled, and the second SIM card 20 is in FDD connected state and not fully scheduled. At this time, the processor may simultaneously configure the target transmit powers PCMAX of the first SIM card 10 and the second SIM card 20 to be: maximum transmit power MTPL. For example, the MTPL may be 26dBm, with the target transmit power PCMAX for each SIM set to 26dBm.

In a second example, as shown in fig. 13, the first SIM card 10 is in a TDD connected state and not fully scheduled, and the second SIM card 20 is in a TDD connected state and not fully scheduled. At this time, the processor may simultaneously configure the target transmit powers PCMAX of the first SIM card 10 and the second SIM card 20 to be: maximum transmit power MTPL. For example, the MTPL may be 26dBm, with the target transmit power PCMAX for each SIM set to 26dBm.

It will be appreciated that in this step, when the communication state is in the third state, only one of the two SIM cards may be in the connected state, which may be in the full schedule state. The adjustment in this case may be included in the embodiment corresponding to fig. 3. Therefore, the embodiments corresponding to fig. 4 and fig. 5 in this disclosure may be used in a scenario where both SIM cards are in a connected state.

In this embodiment, after determining the target transmit Power (PCMAX), uplink power control may be further performed according to the following manner, that is, determining the uplink channel power P (PUSCH) of the SIM card:

The number of RBs allocated to the electronic device is characterized, μ representing the subcarrier spacing. Alpha (j) characterizes the path loss compensation factor, PL (q) _d ) And characterizing the downlink loss detected by the electronic equipment. Delta _TF (i) The power offset value is characterized. f (i, l) characterizes the adjustment of the uplink channel transmit power P (PUSCH).

In connection with the embodiments corresponding to fig. 2 to 4 and the examples of fig. 6 to 13, different link budgets may be corresponding to different traffic states of the SIM card in the present disclosure. Thus, dynamic power configuration is possible. For example, the maximum transmission power of the electronic device is 26dBm, the present disclosure mainly dynamically allocates half of the transmission power of 3dB to the target SIM card (working card), or the two SIMs share the transmission power of 3dB during working, so that the maximum transmission power of 26dBm of the SIM card in the working state can be achieved.

In an exemplary embodiment, the disclosure further proposes a transmitting power determining device, applied to an electronic device, where the electronic device includes at least two SIM cards. As shown in fig. 14, the apparatus of the present embodiment includes: a transmitting module 210, a first determining module 220 and a second determining module 230. The apparatus of this embodiment is used to implement the method shown in fig. 2. The sending module 210 is configured to report capability information to the base station, where the capability information is used to indicate that the maximum transmission power of at least two SIM cards in the electronic device is the maximum transmission power of the electronic device. The first determining module 220 is configured to determine a communication state of the electronic device according to service states of at least two SIM cards in the electronic device. The second determining module 230 is configured to determine a target transmission power of the SIM card according to the communication state, where the target transmission power is equal to or less than a maximum transmission power of the electronic device.

In one exemplary embodiment, still referring to fig. 14, the apparatus of this embodiment comprises: a transmitting module 210, a first determining module 220 and a second determining module 230. The apparatus of this embodiment is used to implement the method shown in fig. 3. Wherein, the first determining module 220 is configured to: and determining that the communication state is a first state in response to only the target SIM card in the at least two SIM cards being in the connected state and the at least two SIM cards except the target SIM card being in the idle state.
