For ease of understanding, the communication process involved in the embodiment of the present application is introduced first.

The maximum transmit power of the terminal equipment

Currently, multiple power classes (power classes, PCs) are defined in the 3rd generation partnership project (3GPP) standard for the maximum transmission power of terminal equipment, and different PCs among multiple PCs correspond to different maximum transmission powers. transmit power.

In some implementation manners, for terminal devices working in different frequency bands, the types of transmit power used to define the power levels are different. For a terminal device operating in a frequency range (frequency range, FR) 1 (ie, a frequency band below 7.125 GHz), the power level can be defined based on conducted power. For example, the maximum transmission power of the terminal equipment in PC1 is 31 dBm, the maximum transmission power of the terminal equipment in PC2 is 26 dBm, and the maximum transmission power of the terminal equipment in PC3 is 23 dBm. For terminal equipment working in FR2 (also known as "millimeter wave frequency band", usually above 24GHz), the power level can be defined according to the air interface radiation power, where the air interface radiation power includes the equivalent isotropic radiation peak power ( peak effective isotropic radiated power, peak EIRP), air interface average radiated power, spherical coverage and other indicators.

As introduced above, regardless of the power level defined based on the transmission power, the actual transmission power of the terminal device at a certain power level usually does not exceed the maximum transmission power in the corresponding power level.

It should be noted that the above power levels only define the theoretical maximum transmission power of the terminal device. When actually transmitting signals, the terminal device can further consider the influence of various factors such as actual transmission conditions and whether there is a human body approaching to determine the actual transmission power of the terminal device. Configurable maximum transmit power (Pcmax). Typically, Pcmax is less than or equal to the maximum transmit power in the power class. Pcmax can be understood as the upper limit of the actual transmission power of the terminal device under the current network device scheduling.

The foregoing actual transmission conditions may include factors such as the number of resources allocated by the network device, resource locations, and the like. The above actual transmission conditions may also include the modulation mode of the signal to be transmitted.

Transmit power control for terminal equipment

Generally, the network device can control the transmit power of the terminal device according to the demodulation requirement of the uplink signal. For ease of understanding, the following uses the terminal device to determine the transmit power of a physical uplink shared channel (PUSCH) as an example.

Assuming that the terminal device needs to transmit PUSCH to the network device on the time slot i through the working carrier f of the cell c, and, for the terminal device, the activated part of the bandwidth is (bandwidth part, BWP) denoted as b, then the terminal device can be based on the formula

Determine the expected transmit power P _PUSCH,b,f,c (i,j,q _d ,l) of the network device.

Wherein, j represents the power control parameter index of network device configuration; l represents the index of dynamic power adjustment; P _{O—PUSCH,b,f,c} (j) represents the cell-level open-loop power control target power configured by network device;

Indicates the number of RBs scheduled to the terminal equipment; PL _b,f,c (q _d ) indicates the link loss corresponding to the working carrier f; α _b,f,c (j) indicates the link loss weighting parameter configured by the network; Δ _{TF , b, f, c} (i) represent parameters related to the modulation mode of the PUSCH; f _{b, f, c} (i, l) represent the transmit power control command TPC in the closed-loop power control.

It should be noted that the cell-level open-loop power control target power configured by the network device is the same for all terminal devices in the cell.

In addition, based on the above formula, it can be seen that the scheduling of the transmission power of the terminal equipment by the network equipment is usually for different carriers, but for the same BWP on the same carrier, the scheduling of the transmission power of the terminal equipment by the network equipment is not the same. The specific implementation of the terminal device is distinguished, that is to say, the network device does not care whether the terminal device realizes the desired transmission power of the network device through one transmission link or multiple transmission links.

How terminal devices at different power levels transmit signals

As mentioned above, at present, the maximum transmission power of the terminal device is only specified by the power level, and there is no restriction on whether the terminal device uses one transmission link or multiple transmission links to transmit signals based on the maximum transmission power. For ease of understanding, the following uses FR1 and FR2 as examples to introduce the way the terminal device transmits signals.

Assume that the power level of the terminal device is PC2 of FR1, and the terminal device has two transmission links: transmission link 1 and transmission link 2, and a power amplifier (Power Amplifier, PA) can be set on each transmission link. In order to ensure that the actual transmit power of the terminal device is less than the corresponding maximum transmit power of PC2, in an implementation manner, referring to FIG. 2 , the terminal device may use two PAs using PC3 to transmit signals. In another implementation manner, referring to FIG. 3 , the terminal device may also use one PC2 PA and one PC3 PA to transmit signals. In another implementation manner, referring to FIG. 4 , the terminal device may also use two PAs of PC2 to transmit signals.

For a terminal device working on FR2, the terminal device usually has multiple antenna arrays (antenna panels) to meet the requirements of the terminal device for transmitting power in various directions, and in some cases, spherical coverage can be achieved.

Referring to Figure 5, assuming that the terminal device has two antenna arrays: antenna array 1 and antenna array 2, and these two antenna arrays work on the same carrier, then based on the above related introductions about terminal device transmit power control, it can be known that the network The expected transmit power of the device is the total transmit power of the two antenna arrays, or in other words, the network device can control the total transmit power of the antenna array 1 and the antenna array 2 through the expected transmit power of the network device.

As introduced above, currently the network device can control the transmit power of the terminal device according to the expected transmit power of the network device. For a terminal device with multiple antenna groups (for example, an antenna array), the network device can only control the total transmission power of the multiple antenna groups through the desired transmission power of the network device, resulting in the network device controlling the transmission power of the terminal device. The method is not accurate enough, thereby reducing the communication quality between the terminal device and the network device.

For example, referring to FIG. 6, when there are multiple transmitting and receiving points (transmission and receiving points, TRP) 1 and TRP2 of a certain network device in the vicinity of the terminal device 610, the terminal device 610 can use the beam formed by the antenna array 1 1 transmits signals to TRP1, and transmits signals to TRP2 through beam 2 formed by antenna array 2. This transmission mode in which the terminal device 610 transmits signals separately through the antenna array 1 and the antenna array 2 can be regarded as multiple-in multiple out (MIMO) transmission of the terminal device 610 on one carrier, and the two The antenna arrays respectively carry data of one layer (layer) in MIMO transmission.

In this case, the space loss between antenna array 1 and TRP1 is space loss 1, and the space loss between antenna array 2 and TRP2 is space loss 2. When the space loss 1 is different from the space loss 2, it may cause the transmission power of the antenna array 1 to be different from that of the antenna array 2, that is, the signal strength of the signal transmitted by the antenna array 1 is different from the signal strength of the signal transmitted by the antenna array 2. There is a difference between the intensities, and this difference may cause a performance degradation of the demodulation of the signal by the network device, thereby affecting the communication quality between the terminal device and the network device.

For another example, referring to FIG. 7, when there is only one TRP of a certain network device around the terminal device 710, the terminal device 710 can transmit a signal to TRP1 through beam 1 formed by antenna array 1, and transmit a signal to TRP1 through beam 2 formed by antenna array 2. TRP1 fires a signal. This transmission mode in which the terminal device 710 transmits signals separately through the antenna array 1 and the antenna array 2 can be regarded as a multiple-in multiple out (MIMO) transmission of the terminal device 710 on one carrier, and the two The antenna arrays respectively carry data of one layer (layer) in MIMO transmission.

In this case, the spatial propagation loss difference between each antenna array of the terminal device 710 and the network equipment is not large, but since the beams used by the antenna arrays to transmit signals are directional beams, different antenna array directions The transmission power required by the same TRP of a network device to transmit a signal will be different, that is, there will be a difference between the signal strength of the signal transmitted by antenna array 1 and the signal strength of the signal transmitted by antenna array 2, and this difference may cause network The performance of the demodulation of the signal by the device is degraded, thereby affecting the communication quality between the terminal device and the network device.

Therefore, in order to avoid the above problems, the embodiment of the present application provides a communication method, and the network device can control the transmit power (also called "first transmit power") of each antenna group of the terminal device through the first information, that is, That is, the network device can control the transmission power of each antenna group of the terminal device to improve the accuracy of the way the network device controls the transmission power of the terminal device, thereby improving the communication quality between the terminal device and the network device. It avoids that in the traditional transmission power control mechanism, the network equipment can only control the total transmission power of multiple antenna groups of the terminal equipment through the transmission power expected by the network equipment, which leads to the accuracy of the way the network equipment controls the transmission power of the terminal equipment. Low.

On the other hand, in the embodiment of the present application, the network device can independently control the transmission power of each antenna array in the terminal device. Correspondingly, the terminal device can use different antenna arrays to communicate with one or more TRPs, so the terminal can The device has a higher degree of freedom to adjust the transmission power, thereby improving the flexibility of the terminal device to use multiple antenna arrays. It avoids that under the traditional transmission power control mechanism, the network equipment can only use one transmission power (that is, the transmission power expected by the network equipment) to control, but cannot use different transmission powers for each antenna array of the terminal equipment, resulting in the terminal equipment having The degree of freedom of transmitting power adjustment is low.

The following describes the communication method in the embodiment of the present application with reference to FIG. 8 . The method shown in FIG. 8 includes step S810 and step S820 .

In step S810, the network device sends first information to the terminal device.

The foregoing first information is used to indicate the first transmit power of each antenna group among the plurality of antenna groups expected (also called "scheduled") by the network device. Wherein, each antenna group includes some antennas of the terminal equipment. In other words, the antenna of the terminal device belongs to multiple antenna groups, and each antenna group in the multiple antenna groups includes one or more antennas of the terminal device.

It should be noted that the multiple antenna groups may include all antennas of the terminal device, and of course, the multiple antenna groups may also include some antennas of the terminal device, which is not limited in this embodiment of the present application.

In some implementation manners, the antennas included in each antenna group above may refer to antennas of the terminal device. In some other implementation manners, the antennas included in each antenna group above may include other communication elements on the communication path where the antennas are located, where the communication elements may include, for example, PAs, phase shifters, antenna elements and other power transmission components.

In this embodiment of the present application, the network device may control the transmit power of each antenna at a granularity of antennas, and at this time, each antenna group in the foregoing plurality of antenna groups may include one antenna. Certainly, the network device may control the transmit power of each antenna group at the granularity of multiple antennas, and in this case, each antenna group in the above multiple antenna groups may include multiple antennas. In addition, the network device can control the transmit power of each antenna array at the granularity of antenna arrays. At this time, the antennas included in each antenna group of the above-mentioned multiple antenna groups can belong to the corresponding antenna array, or in other words, multiple antenna groups Different antenna groups correspond to an antenna array. The network device can also control the transmit power of each antenna port with the antenna port as the granularity. At this time, the antennas included in each antenna group in the above-mentioned multiple antenna groups can correspond to one antenna port, or in other words, different The antenna group corresponds to an antenna port.

In some implementation manners, the first information includes an identifier corresponding to each antenna group, and/or, a power control parameter used to determine the first transmit power of each antenna group.

The foregoing power control parameters of the first transmit power are used to determine the first transmit power. In some implementations, the control parameters of the above-mentioned first transmission power may include some or all of the power control parameters in the formula introduced in the above section about terminal device transmission power control, and some or all of the power control parameters are related to the antenna array Corresponding power control parameters. Of course, the power control parameter of the first transmit power may also use other parameters, which is not limited in this embodiment of the present application.

For ease of understanding, the following uses the transmit power control mode in a single-carrier scenario as an example to introduce the method in the example of the present application. As shown in the formula introduced in the section about terminal device transmit power control above, the transmit power control mechanism of terminal devices will configure open-loop target transmit power, RB resources, link loss weighting parameters, modulation mode adjustment parameters, and closed-loop parameters for each carrier. Transmit power control commands. Correspondingly, the terminal device can calculate the spatial propagation loss PL according to the transmission strength and reception strength of the downlink signal (eg, reference signal), and calculate the expected transmission power of the network device through a formula in combination with the above parameters.

Then, in the example of this application, in order to control the transmission power at the granularity of the antenna array, the power control parameters based on the antenna array can be introduced into the power control. That is, the public control parameters can be configured at the granularity of the antenna array, that is, one or more parameters in the above-mentioned open-loop target transmit power, RB resources, link loss weighting parameters, modulation mode adjustment parameters, and closed-loop transmit power control instructions It is configured at the granularity of the antenna array. Taking TPC_identity 1 as an example, where identification 1 is the identification of antenna array 1, then the network device can control the terminal device to adjust the transmit power of antenna array 1 through TPC_identity 1.

The above first information may explicitly indicate the correspondence between each antenna group in the terminal device and the power control parameter of the first transmit power, that is, the first information may include the identifier of each antenna group in the terminal device, and A power control parameter identifying a corresponding first transmit power for each antenna group.

Of course, the above first information may implicitly indicate the correspondence between each antenna group in the terminal device and the power control parameter of the first transmit power, that is, the first information may only include the The power control parameters of the first transmission power, and the power control parameters of the first transmission power of each antenna group of the terminal device are carried in the first information in a preset order, where the order is used to indicate that each antenna group of the terminal device is related to Correspondence between power control parameters of the first transmit power carried in the first information. For example, the order of the power control parameters of the first transmit power carried in the first information is based on the order of the antenna group identifiers in the terminal device from small to large, that is, the first first transmit power carried in the first information corresponds to The antenna group indicated by the smallest identifier in the terminal device, the second first transmit power carried in the first information corresponds to the antenna group indicated by the second smallest identifier in the terminal device, and so on, the last first transmit power carried in the first information One transmit power corresponds to the antenna group indicated by the largest identifier in the terminal device.

It should be noted that if different antenna groups among the multiple antenna groups correspond to one antenna array, then the identifier corresponding to each antenna group may be the identifier (for example, Ant ID) of each antenna array. If different antenna groups among the multiple antenna groups correspond to one antenna port, the identification corresponding to each antenna group includes the identification (for example, AntPort ID) of each antenna port. For example, antenna port 0 configured in the network may be mapped to antenna array 0, and then the identifier of antenna array 0 may be antenna port 0. For another example, antenna port 1 may be mapped to antenna array 2, and the identifier of antenna array 2 may be antenna port 1.

In step S820, the terminal device determines the first transmit power of each antenna group in the plurality of antenna groups based on the first information.

In this embodiment of the present application, the actual transmit power of each antenna array may be the same as or different from the first transmit power of each antenna array indicated in the first information. In some implementation manners, the terminal device may directly use the first transmit power corresponding to each antenna group indicated in the first information as the actual transmit power of each antenna group. In other implementation manners, the terminal device may adjust the first transmit power of each antenna group indicated in the first information to obtain the adjusted transmit power, and use the adjusted transmit power as the The actual transmit power of the group. The foregoing adjustment may include increasing the first transmit power of each antenna array or decreasing the first transmit power of each antenna array.

Of course, in some implementation manners, the terminal device may only adjust the first transmit power of some antenna groups in the multiple antenna groups. In some other implementation manners, the terminal device may also adjust the first transmit power of each antenna group in the multiple antenna groups.

In some cases, the sum of the first transmit power configured by the network device for multiple antenna groups may be greater than the maximum transmit power of the terminal device. At this time, part or all of the multiple antenna groups (hereinafter referred to as The first transmit power corresponding to the "first antenna group") is adjusted to obtain the adjusted transmit power (also known as the second transmit power), so that the sum of the first transmit power corresponding to multiple antenna groups is less than or equal to the maximum transmit power power. Wherein, the foregoing adjustment may be performed by a network device, or may be performed autonomously by a terminal device, which is not limited in this embodiment of the present application.

In the single-carrier scenario, three adjustment methods are introduced below by taking the first antenna group and the second antenna group as examples, where the second antenna group may be an antenna group other than the first antenna group among the multiple antenna groups. It should be noted that there are many other adjustment methods applicable to the embodiment of the present application besides the following three, which will not be repeated for the sake of brevity.

Adjustment method 1: adjust the transmit power based on the priorities corresponding to the multiple antenna groups.

Among the multiple antenna groups, the transmit power required by the antenna group with a higher priority (that is, the first transmit power) is satisfied first, and the transmit power of the antenna group with a lower priority is reduced. That is, in the foregoing, the priority of the first antenna group is lower than the priority of the second antenna group, and the terminal device reduces the first transmit power of the first antenna group to the second transmit power.

In some implementations, in order to make the sum of the adjusted transmit powers of multiple antenna groups less than or equal to the maximum transmit power, the first transmit power of the antenna group with a higher priority among the multiple antenna groups may be satisfied first, and based on The first transmit power and the maximum transmit power of the antenna group with higher priority calculate the remaining transmit power, and then distribute the remaining transmit power among the antenna groups with lower priority.

It should be understood that when the remaining transmit power is 0, the transmit power of the antenna group with a lower priority may also be 0. In addition, when the remaining transmission power is not 0, the remaining transmission power can be allocated among the antenna groups with lower priority according to the preset rules, where the preset rules can be average distribution or distribution in proportion. This is not specifically limited.

In some implementations, in order to improve the flexibility of the terminal device in adjusting the transmit power of multiple antenna groups, the priorities of the above multiple antenna groups may be indicated by the network device, that is, the above method further includes: the terminal device receives the indication sent by the network device Information, indicating that the information is used to indicate the priority of each antenna group in the multiple antenna groups. Correspondingly, the terminal device determines the first antenna group from the multiple antenna groups based on the indication information.

The foregoing first antenna group may include one or more antenna groups with a priority lower than a priority threshold among multiple antenna groups, where the priority threshold may be pre-configured by a network device or pre-defined by a protocol. Of course, the above-mentioned first antenna group may also be a preset number of antenna groups among the multiple antenna groups. For example, when the preset number is 2, the first antenna group may include two antennas with lower priority among the multiple antenna groups. Group. Wherein, the preset number may be pre-configured by a network device or pre-defined by a protocol.

In some other implementation manners, the priority of the above multiple antenna groups may also be independently determined by the terminal device, for example, the terminal device may determine based on the service type to be transmitted corresponding to each antenna group in the multiple antenna groups. Certainly, the priorities of the foregoing multiple antenna groups may also be predefined by a protocol, which is not specifically limited in this embodiment of the present application.

Adjustment manner 2: adjust the transmit power based on the magnitude of the first transmit power of the multiple antenna groups.

That is to say, the transmit power of the first antenna group expected by the network device is greater than the transmit power of the second antenna group expected by the network device, or in other words, the first transmit power of the first antenna group is greater than the first transmit power of the second antenna group .

Wherein, the above-mentioned first antenna group may include an antenna group whose first transmission power is greater than a preset value among multiple antenna groups, where the preset value may be pre-configured by a network device or pre-defined by a protocol. The above-mentioned first antenna group can also be a preset number of antenna groups among the multiple antenna groups. For example, when the preset number is 2, the first antenna group can include two antennas with higher first transmission power among the multiple antenna groups. Group. Wherein, the preset number may be pre-configured by a network device or pre-defined by a protocol.

In some implementation manners, in order to make the sum of the adjusted transmit powers of the multiple antenna groups less than or equal to the maximum transmit power, the first transmit power of the antenna group with the lower first transmit power among the multiple antenna groups may be preferentially satisfied, The remaining transmit power is calculated based on the first transmit power and the maximum transmit power of the antenna group with the lower first transmit power, and then the remaining transmit power is allocated among the antenna groups with the higher first transmit power.

It should be understood that when the remaining transmit power is 0, the transmit power of the antenna group with the first greater transmit power may also be 0. In addition, when the remaining transmission power is not 0, the remaining transmission power can be distributed among the antenna groups with higher first transmission power according to the preset rules, wherein the preset rules can be average distribution, or distribution according to the proportion, the implementation of this application The example does not specifically limit this.

In addition, the second adjustment method above may be executed by a terminal device or by a network device, which is not limited in this embodiment of the present application.

Adjustment manner 3: Adjust the transmit power of the first antenna group based on the power headroom of the terminal device.

In order to make the adjusted sum of the transmit powers of the multiple antenna groups less than or equal to the maximum transmit power, the second transmit power of the first antenna group is determined based on the power headroom of the terminal device.

The third adjustment method above may be performed by the terminal device independently, or may be performed by the network device. When executed by a network device, the power headroom of the terminal device may be sent to the network device through a power headroom report PHR. Correspondingly, the network device determines the second transmit power of the first antenna group based on the power headroom of the terminal device, and indicates the second transmit power of the first antenna group to the terminal device. That is to say, the above method further includes: the network device sends second information to the terminal device, the second information is used to indicate the second transmission power of the first antenna group expected by the network device; the terminal device adjusts the first antenna group based on the second information The transmit power of is the second transmit power.

For example, when the power headroom of the terminal device is less than or equal to 0, it means that the total transmit power of the terminal device on different antenna arrays (that is, the sum of the first transmit powers of multiple antenna arrays) has exceeded the maximum transmit power. , the network device can use the TPC_AntID command to determine the transmit power of the antenna array identified by the AntID.

For another example, in the case that all antenna arrays of a terminal device work on the same carrier, when the power headroom of the terminal device is less than or equal to 0, it indicates that the total transmit power of the terminal device on different antenna arrays (that is, the total transmission power of multiple antenna arrays The sum of the first transmit powers) has exceeded the maximum transmit power. At this time, the network device can simultaneously adjust the total transmit power on all antenna arrays through the carrier TPC command.

Combining the adjustment methods 1 to 3 above, the method of adjusting the transmit power of the antenna array in the single-carrier scenario is introduced. The following describes the method of adjusting the transmit power of the antenna array in the multi-carrier (also known as "frequency band combination") scenario. For ease of understanding, the multi-carrier scenario applicable to this embodiment of the present application is firstly introduced below with reference to FIG. 9 to FIG. 10 .

FIG. 9 is a schematic diagram of a multi-carrier scenario applicable to an embodiment of the present application. Referring to FIG. 9 , it is assumed that the terminal device has two antenna arrays: antenna array 1 and antenna array 2 . Wherein, the antenna array 1 can work on the carrier CC1 and the carrier CC2, and communicate with the TRP1 of the network device. The antenna array 2 can work on the carrier CC1 and communicate with the TRP2 of the network equipment. That is to say, the carrier CC1 can be transmitted on two antenna arrays at the same time, and the carrier CC2 is only transmitted on the antenna array 1.

FIG. 10 is a schematic diagram of a multi-carrier scenario applicable to an embodiment of the present application. Referring to FIG. 10 , it is assumed that the terminal device has two antenna arrays: antenna array 1 and antenna array 2 . Wherein, the antenna array 1 can work on the carrier CC1 and the carrier CC2, and communicate with the TRP1 of the network device. The antenna array 2 can work on the carrier CC1 and the carrier CC2, and communicate with the TRP2 of the network device. That is to say, both the carrier CC1 and the carrier CC2 can transmit on the two antenna arrays at the same time.

Regardless of the multi-carrier scenario shown in FIG. 9 or the multi-carrier scenario shown in FIG. 10 , when the transmit power of each carrier is adjusted independently, the adjustment method described above can be used. However, when the transmit power needs to be adjusted simultaneously for multiple carriers (for example, the carrier CC1 and the carrier CC2), how to deal with the relationship between the power allocation between different carriers and the power allocation between different antenna arrays is an urgent problem to be solved.

Therefore, in order to solve the above problem, the embodiment of the present application further provides two adjustment methods, namely adjustment method 4 and adjustment method 5, to standardize the adjustment method of transmit power in a multi-carrier scenario. In the multi-carrier scenario, the following uses the first antenna group and the second antenna group as examples to introduce the method of adjusting the transmission power. It should be noted that the adjustment manner described below may be performed by a terminal device or a network device, which is not limited in this embodiment of the present application.

Adjustment method 4. Carrier priority adjustment method.

In this adjustment mode, when the sum of the first transmit power of multiple antenna groups is greater than the maximum transmit power, the transmit power of the carrier with higher carrier priority can be satisfied first, and the carrier with lower carrier priority can be reduced. The transmit power of each antenna array within. That is to say, when the carrier priority of the carrier working on the first antenna group is lower than that of the carrier working on the second antenna group, the transmit power of the second antenna group can use the first transmit power, but it needs to be reduced The transmit power of the first antenna group.

Usually, in order to make the sum of the adjusted transmit powers of multiple antenna groups less than or equal to the maximum transmit power, the transmit power of the carrier with higher carrier priority (that is, the first transmit power) can be satisfied first, and based on the carrier priority The first transmit power and the maximum transmit power of the high carrier determine the remaining transmit power of the terminal device. The remaining transmit power is then allocated to each antenna array working in a carrier with a lower carrier priority.

It should be noted that when power allocation is performed between antenna arrays working in a carrier with a lower carrier priority, the adjustment method described above can be used to adjust, of course, other methods can also be used for adjustment. This application The embodiment does not limit this.

In addition, in some implementation manners, the above-mentioned carrier with a higher carrier priority may be a carrier with a carrier priority higher than the carrier priority threshold in a multi-carrier scenario, and correspondingly, a carrier with a lower carrier priority may be a carrier with a lower carrier priority in a multi-carrier scenario. Carrier Priority Carriers with a priority lower than the priority threshold. Wherein, the carrier priority threshold can be configured by the network device or predefined by the protocol. In some other implementation manners, when the multi-carrier scenario only includes two carriers, the carrier with a higher carrier priority may be the carrier with a higher carrier priority among the two carriers, and correspondingly, the carrier with a lower carrier priority may is the carrier with the lowest carrier priority among the two carriers.

Usually, a carrier with a higher carrier priority is used to carry control information. Using the adjustment method in this embodiment of the present application, the success rate of transmission of control information in a carrier with a higher carrier priority can be improved.

Adjustment method 5. Antenna array priority adjustment method.

In this adjustment mode, when the sum of the first transmission powers of multiple antenna groups is greater than the maximum transmission power, the transmission power of the antenna array with higher priority can be satisfied first (that is, the transmission power of the antenna array with higher priority may be the first transmit power), and reduce the transmit power of the lower-priority antenna array. That is to say, when the priority of the first antenna group is lower than that of the second antenna group, the transmit power of the second antenna group may use the first transmit power, but the transmit power of the first antenna group needs to be reduced.

Usually, in order to make the sum of the adjusted transmit powers of multiple antenna groups less than or equal to the maximum transmit power, the transmit power of the antenna array with a higher priority (that is, the first transmit power) can be satisfied first, and based on the higher priority The sum of the first transmit power and the maximum transmit power of the antenna array of the antenna array determine the remaining transmit power of the terminal device. The remaining transmit power is then allocated to antenna arrays with lower priority.

In some implementation manners, when performing power allocation among antenna arrays with lower priority, power allocation may be performed according to the priority of the carriers on which the antenna array with lower priority operates, that is, the In the antenna array, the transmit power of the carrier with higher carrier priority can be satisfied firstly, and the transmit power of each antenna array working in the carrier with lower carrier priority can be reduced. That is to say, if the antenna groups in the first antenna group work on different multiple carriers, the above method further includes: adjusting the antenna group in the first antenna group based on the priority of the carrier corresponding to the antenna group in the first antenna group transmit power.

In addition, for the selection between the antenna array with higher priority and the antenna array with lower priority, please refer to the relevant introduction in the first adjustment method. For the configuration method of the priority, please refer to the relevant introduction in the first adjustment method above, and for the sake of brevity, details are not repeated here.

In the embodiment of the present application, the transmit power is preferentially adjusted based on the priorities of the antenna arrays, which is beneficial to preferentially guarantee the communication quality between certain antenna arrays and network devices. For example, a higher priority can be set for antenna arrays with lower transmission power, so that the connection between such antenna arrays and network devices can be guaranteed.

In some cases, in order to improve the rationality of the network device adjusting the transmit power of the antenna groups, the terminal device may first send capability information to the network device to indicate the number of multiple antenna groups. In some implementation manners, the number of multiple antenna groups may be understood as the maximum number of antenna groups that can be supported by the terminal device for independent transmission power adjustment. In other implementation manners, the capability information may be indicated by the MIMO communication capability of the terminal device.

It should be noted that the above capability information can be sent to the network device when the terminal device initially accesses the network device. Of course, the above capability information can also be sent to the network device by the terminal device at any time before step S810. This application implements The example does not specifically limit this.
