It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

multi-carrier communications

In order to improve the throughput of communication systems, multi-carrier communication is introduced in some communication systems, so that terminal devices can use multiple carriers to send or receive signals/data. Multi-carrier communication scenarios may include multiple scenarios, such as carrier aggregation (CA) scenarios, dual connectivity (DC) scenarios, etc., which are not limited in the embodiments of this application.

The multiple carriers can be understood as the abbreviation of multiple carrier units (component carriers, CCs), where the carrier units can also be called component carriers, component carriers, etc., which are not limited in the embodiments of the present application.

When terminal equipment communicates based on multiple carriers, based on the location relationship of the network devices corresponding to the multiple carriers, the multi-carrier communication can be divided into multi-carrier communication in the scenario of co-location (collocation), and multi-carrier communication in the scenario of non-collocation ( Multi-carrier communication in non-collocated) scenarios. The co-site address mentioned in the embodiment of this application may mean that network devices corresponding to multiple carriers are deployed at the same site location. For example, the network devices corresponding to multiple carriers are the same network device. Correspondingly, the different site addresses mentioned in the embodiments of this application may mean that network devices corresponding to multiple carriers are deployed at different site locations. In some embodiments, sharing a shared site address can also be understood as sharing a site, and not sharing a site address can also be understood as not sharing a site. This is not limited in the embodiments of the present application.

Multi-carrier communication in a co-site scenario is a typical scenario in the network. For example, it can be applied to the situation of multi-carriers in the band. This is considering that during network deployment, for multi-carriers in the band, the frequency between the carriers The similarity makes it feasible to deploy multiple carriers at the same site.

Figure 2 is an example diagram of multi-carrier communication in a co-site scenario provided by an embodiment of the present application. As shown in Figure 2, the terminal device 120 is configured with CC1 and CC2. CC1 corresponds to the network device 110a, and CC2 corresponds to the network device 110b. The network device 110a and the network device 110b are deployed at the same site location, that is, CC1 and CC2 can be considered to be in the same site. address scenario.

Multi-carrier communication in the scenario of different sites is also a typical scenario in the network, and can be applied to millimeter wave cells, for example. This is because the total width of millimeter wave frequency bands is usually defined to reach several GHz, and usually, spectrum allocation in various countries and regions is in stages, which also results in operators receiving spectrum in stages. And most of them are discontinuous, so the network deployment of multiple carriers is not simultaneous. And because millimeter wave cell coverage is very small, it is usually not a continuous coverage but a hot spot supplement for low-frequency band networks, making it feasible to deploy multiple carriers at different sites.

Figure 3 is an example diagram of multi-carrier communication in a scenario of different site addresses provided by an embodiment of the present application. As shown in Figure 3, the terminal device 120 is configured with CC1 and CC2. CC1 corresponds to the network device 110a, and CC2 corresponds to the network device 110b. The network device 110a and the network device 110b are deployed at different site locations. That is, CC1 and CC2 can be considered to be in different locations. In the scenario of site address.

beamforming

A beam can be understood as a communication resource (airspace resource), and a carrier can use the beam to send and receive signals/data. In the scenario of multi-carrier communication, different carriers can use different beams to send and receive signals/data, and these different beams can be considered as different airspace resources.

The beams may include transmit beams (or transmit beams) and receive beams. Taking the communication between terminal equipment and network equipment as an example, the beam used by the terminal equipment when sending signals to the network equipment is the uplink transmitting beam; the beam used by the terminal equipment when receiving the signals sent by the network equipment is the downlink receiving beam; the network equipment uses the downlink receiving beam to transmit signals to the terminal equipment. The transmit beam used by the device when sending signals is the downlink transmit beam; the beam used by the network device when receiving the signal sent by the terminal device is the uplink receive beam.

Terminal devices can beamform carrier waves for communication. Beamforming, also known as beamforming, is a signal processing technology that uses an array of sensors to send and receive signals in a direction. Beamforming can use an antenna array composed of multiple antenna elements to form a beam to transmit and receive signals. When the terminal equipment performs beamforming, the parameters of the basic unit of the phase array can be adjusted so that signals at certain angles obtain constructive interference, while signals at other angles obtain destructive interference. Beamforming can be used on both the signal transmitting end and the signal receiving end.

In practical applications, beamforming can include multiple types, such as digital beamforming, analog beamforming, and hybrid beamforming. Among them, digital beamforming forms beams through the control of analog-to-digital converters and digital-to-analog converters. When simulating beam shaping to form a beam, a phase shifter is applied, and the direction of the beam can be adjusted by adjusting the direction of the phase shifter.

After the terminal equipment performs beamforming on the carrier, the beam can be divided into a wide beam and a narrow beam according to the angular coverage of the formed beam. For example, when a terminal device works in a low-frequency band or a medium-frequency band, it can form an omnidirectional beam or a beam with a wider angle to send and receive signals/data. This omnidirectional beam or a beam with a wider angle can be called a wide beam. . Alternatively, when the terminal equipment works in a high-frequency band (for example, millimeter wave band, usually the millimeter wave operating frequency is above 10GHz), it can form narrow beams to send and receive signals/data. These narrow beams have relatively strong directions. (directivity), for details, please refer to the example of terminal equipment communicating based on narrow beams shown in Figure 4. The reason why terminal equipment forms narrow beams in high-frequency bands to send and receive signals/data is because the spatial propagation loss of electromagnetic waves in high-frequency bands is very large, resulting in limited coverage of electromagnetic wave signals, and terminal equipment forms narrow beams in high-frequency bands. Using beams to transmit and receive signals/data can overcome large spatial losses and improve the beam coverage of terminal equipment.

When a terminal device performs beamforming on multiple carriers, according to the terminal device's ability to perform beamforming, the terminal device can be divided into a terminal device with common beam management capabilities and a terminal device with independent beam management capabilities. The common beam management capability may mean that the terminal equipment can only perform beamforming on multiple carriers according to the same beamforming factor (or beamforming parameter) at the same time. The independent beam management capability may mean that the terminal device can perform beamforming on multiple carriers according to different beamforming factors at the same time.

Figure 5 is an example diagram of a terminal device with public beam management capabilities provided by an embodiment of the present application. In the example of FIG. 5 , the terminal device 120 is configured with only one set of transmitting/receiving antenna units. When the terminal device 120 needs to perform beamforming on CC1 and CC2 at the same time, it can only use one set of beamforming factors to simultaneously perform beamforming on CC1 and CC2 at the same time. CC2 performs beamforming, so that the beam directions of the beams formed by beamforming are the same. In other words, only one CC can perform beamforming at the same time, and another CC can perform beamforming and generate beams according to the same beamforming factor. For example, when the priority of the signal/data carried by CC1 is high, it can be performed according to CC1 performs beamforming, and CC2 performs beamforming with reference to the beamforming factor of CC1.

For terminal equipment with public beam management capabilities, it only needs to have a set of transmitting/receiving antenna units, the implementation complexity is low, and the cost and power consumption are relatively low. However, since different operating frequency bands share the same set of transmitting/receiving antenna units, beamforming can only be performed on one frequency band at the same time, which means that the beam of one frequency band can only be accurately pointed in one direction at the same time. Therefore, in most cases, terminal equipment with common beam management capabilities works in a cell scenario where multiple carriers are at the same site.

Figure 6 is an example diagram of a terminal device with independent beam management capabilities provided by an embodiment of the present application. In the example of FIG. 6 , the terminal device 120 is configured with multiple groups (two or more groups) of transmitting/receiving antenna units. When the terminal device 120 needs to perform beamforming on CC1 and CC2 at the same time, different beams can be used at the same time. The shaping factor performs beamforming on CC1 and CC2 at the same time, so that the beam directions of the beams formed by the beamforming are different. In other words, beamforming can be performed on different CCs at the same time and beams can be generated. For example, at the same time, the first beamforming factor is used for beamforming CC1, and the second beamforming factor is used for CC2. Give shape.

For terminal equipment with independent beam management capabilities, since multiple independent beams can be generated at the same time, which means that the terminal equipment can point the beams in different directions at the same time, therefore, terminal equipment with independent beam management capabilities have more It has high flexibility and can work in cell scenarios where multiple carriers are at different sites.

Transmit power control of terminal equipment

Under the existing power control mechanism, the transmit power of the terminal device is limited, and the transmit power of the terminal device is required not to be less than a certain value and not greater than another value. The greater the transmit power of the terminal device, the greater the uplink coverage. Therefore, requiring the transmit power of the terminal device not to be less than a certain value can ensure the uplink coverage capability of the terminal device. However, the transmission power of the terminal equipment cannot be too large. If the transmission power is too high, it will affect or cause harm to the human body. Therefore, the existing power control mechanism also requires that the transmission power of the terminal equipment cannot be greater than a certain value.

Optionally, the limit on the transmit power of the terminal device may include a limit on the directional peak transmit power, that is, the transmit power of the terminal device in each direction cannot be less than a certain value and cannot be greater than another value.

When the terminal equipment works in a single-carrier scenario, the above power control mechanism prevents the uplink transmit power of the single carrier from exceeding the limit of the maximum peak transmit power, and at the same time, it needs to meet the limit of the minimum peak transmit power. Figure 7 gives an example of transmit power control of a single carrier. The example in Figure 7 takes the directional peak transmit power as an example. The uplink transmit power of the single carrier in each direction cannot exceed the equivalent omnidirectional radiation power. Maximum peak value (max peak equivalent isotropic radiated power, max peak EIRP) requirement, and cannot be lower than the minimum peak value of EIRP (min peak EIRP) requirement.

When the terminal device works in a multi-carrier scenario, such as an in-band multi-carrier scenario, under the above power control mechanism, it will be based on the multi-carrier power limitation mode (multi-carrier-based power limitation can also be called joint power limitation). The power is controlled so that the sum of the uplink transmit powers of the multiple carriers (the total transmit power of the multiple carriers) meets the limit of the peak transmit power, for example, it cannot exceed the limit of the maximum peak transmit power. Figure 8 gives an example of multi-carrier transmit power control. The example in Figure 8 still takes the directional peak transmit power as an example. The sum of the uplink transmit powers of the multiple carriers in each direction cannot exceed max peak EIRP. Require.

In a multi-carrier scenario, the current limitation on the total transmit power of multiple carriers of terminal equipment is mainly due to the fact that the power superposition of multiple carrier transmit signals will significantly increase the peak power, potentially causing harm to the human body. Especially in the in-band multi-carrier scenario, co-site deployment is feasible due to the similar frequencies between carriers. Therefore, in many cases the transmit beams of multiple in-band carriers of terminal equipment are superimposed in the same direction, as shown in Figure As shown in Figure 9, if CC1 and CC2 are deployed at the same site, the directions of the transmit beams of CC1 and CC2 may be the same, which doubles the total transmit power of multiple carriers of the terminal equipment. In this case, if the total transmit power of multiple carriers is not limited and the maximum transmit power capability of a single carrier is adopted, it is likely that the transmit power of the terminal device will exceed the regulatory requirements.

However, if the multi-carrier power limitation mode limits the uplink transmit power of multiple carriers, this actually reduces the maximum transmit power capability of each carrier, resulting in poor uplink coverage of the terminal equipment. Especially when the terminal equipment operates in a high-frequency band (such as the millimeter wave band), the transmit power of the terminal equipment is crucial for uplink coverage and uplink data transmission. Therefore, it is necessary to consider how to make full use of the transmit power capability of the terminal equipment as much as possible.

Taking multiple carriers of terminal equipment deployed at different sites as an example, the beam directions of the uplink transmit beams of multiple carriers may be different. As shown in Figure 10, CC1 and CC2 are deployed at different sites, then CC1 and The directions of the uplink transmit beams of CC2 are different. In this case, the superposition effect of the transmit power of multiple carriers is not obvious. Multi-carrier-based power limitation will result in the transmit power capability of each carrier not being fully utilized. This results in poor uplink coverage of the terminal equipment.

In response to the above problems, embodiments of the present application provide a wireless communication method, terminal equipment, and network equipment to improve the uplink coverage of the terminal equipment. First, the method embodiments provided by the embodiments of this application are introduced.

FIG. 11 is a schematic flowchart of a wireless communication method provided by an embodiment of the present application. The method in Figure 11 is described from the perspective of interaction between terminal equipment and network equipment. The terminal device and the network device may be, for example, the terminal device 120 and the network device 110 in FIGS. 1 to 10 . The method in Figure 11 includes step S1110, which step will be described in detail below.

In step S1110, the terminal device communicates with the network device based on multiple carriers.

In the embodiment of this application, multiple carriers refer to two or more carriers. The multiple carriers may use the same frequency band resources or may use different frequency band resources, which is not limited in the embodiments of the present application.

Among the multiple carriers, each carrier may correspond to an independent cell, wherein the carrier corresponding to the primary cell may be understood as the primary carrier, and the carrier corresponding to the secondary cell may be understood as the secondary carrier.

In some embodiments, the multiple carriers may be configured by the network device to the terminal device. For example, they may be configured by the network device corresponding to the main carrier.

The embodiments of this application do not specifically limit the co-site relationship of multiple carriers. In some embodiments, the co-site relationship of multiple carriers may be: multiple carriers have a co-site relationship (or co-site deployment). For example, multiple carriers include CC1, CC2, and CC3, and the network devices corresponding to CC1, CC2, and CC3 are the same, that is, CC1, CC2, and CC3 are deployed at the same site. In some embodiments, the co-site relationship between multiple carriers may be: the multiple carriers have a non-co-site relationship (or non-co-site deployment). For example, multiple carriers include CC1, CC2, and CC3, and the network devices corresponding to CC1, CC2, and CC3 are different, that is, CC1, CC2, and CC3 are deployed at different sites. In some embodiments, the co-site relationship of multiple carriers may be: some of the multiple carriers have a co-site relationship, and some carriers have a non-co-site relationship. For example, multiple carriers include CC1, CC2 and CC3. The network equipment corresponding to CC1 and CC2 is the same, but the network equipment corresponding to CC3 is different from CC1 and CC2. That is, CC1 and CC2 have a co-site relationship, but CC1 and CC3 are not. Shared site relationship, CC2 and CC3 also have a non-shared site relationship.

In some embodiments, the beam directions between the beams corresponding to the multiple carriers are the same. It should be understood that the beams corresponding to multiple carriers may refer to the downlink transmit beams corresponding to the carriers, the downlink receive beams corresponding to the carriers, or the uplink transmit beams corresponding to the carriers, etc. The embodiments of this application do not limited.

Optionally, if multiple carriers have a co-site relationship, it can be understood that the beam directions between the beams corresponding to the multiple carriers are the same. However, this application is not limited to this. For example, when the multiple carriers are actually deployed at the same site, due to the influence of multipath or other reasons, the directions of the incoming waves of the multiple carriers may be far different when they arrive at the terminal equipment, then The beam directions between the beams corresponding to the multiple carriers may also be different.

In some embodiments, the beam directions between the beams corresponding to the multiple carriers are different.

Optionally, if multiple carriers do not share the same site address, it can be understood that the beam directions between the beams corresponding to the multiple carriers are different. However, this application is not limited to this. For example, when the multiple carriers are actually deployed at different sites, due to the influence of multipath or other reasons, the direction of arrival of the multiple carriers may be the same when they arrive at the terminal equipment, then the direction of the waves may be the same. The beam directions between the beams corresponding to multiple carriers may also be the same.

The terminal device can communicate with one or more network devices based on the multiple carriers. When a terminal device communicates with a network device based on multiple carriers, it can be understood that the multiple carriers have a co-site relationship, and the network devices corresponding to the multiple carriers are the same. When a terminal device communicates with multiple network devices based on multiple carriers, it can be understood that the multiple carriers do not share the same site address, and some or all of the multiple carriers correspond to different network devices.

When a terminal device communicates with a network device based on multiple carriers, the power control modes corresponding to the uplink transmission powers of the multiple carriers may be the same or different. The embodiments of this application are not limited to this, and will be described later. Combining the first carrier and the second carrier, the power control mode corresponding to the uplink transmit power of the multiple carriers is described in detail, which will not be described again here. In some embodiments, the power control mode may also be called a power control strategy, a power control mechanism, a power control method, etc., which is not limited in the embodiments of the present application.

For any one of the multiple carriers, when the terminal device communicates with the network device based on the carrier, the terminal device can use the uplink transmit power of the carrier to send signals/data to the network device, where the uplink transmit power of the carrier It can also be understood as the transmit power of the terminal device. Correspondingly, when the network device communicates with the terminal device based on the carrier, the network device can use the downlink transmit power of the carrier to send signals/data to the terminal device. The downlink transmit power of the carrier can also be understood as the transmit power of the network device.

The multiple carriers may include a first carrier and a second carrier, and the first carrier and the second carrier are any two carriers included in the multiple carriers. The embodiment of the present application does not limit the co-site relationship between the first carrier and the second carrier. The first carrier and the second carrier may have a co-site relationship or may not have a co-site relationship.

In some embodiments, the first carrier may correspond to the first beam, the second carrier may correspond to the second beam, and the beam direction of the first beam and the beam direction of the second beam may be the same or different.

The embodiments of this application do not limit the types of the first beam and the second beam. For example, the first beam may be one of the following beams: a downlink transmit beam of the first carrier, a downlink receive beam of the first carrier, and The uplink transmit beam of the first carrier. The second beam may be one of the following beams: a downlink transmit beam of the second carrier, a downlink receive beam of the second carrier, and an uplink transmit beam of the second carrier.

When the terminal device communicates with the network device based on the first carrier and the second carrier, the power control mode of the uplink transmit power of the first carrier and the power control mode of the uplink transmit power of the second carrier may be the same or different. .

It should be understood that the power control mode mentioned in the embodiments of this application may include a mode based on single-carrier power limitation (which may also be called independent power limitation, independent power control) and a mode based on multi-carrier power limitation (joint power limitation, joint power control). control) mode.

In some embodiments, the terminal device may limit the uplink transmit power of the first carrier and the uplink transmit power of the second carrier based on a single-carrier power limit mode, or in other words, the power control of the uplink transmit power of the first carrier and The power control of the uplink transmit power of the second carrier is based on the power limit of a single carrier.

Power limitation based on a single carrier may mean that the terminal device separately limits the maximum uplink transmission power of the first carrier and the maximum uplink transmission power of the second carrier, without limiting the uplink transmission power of the first carrier and the second carrier. The maximum power of the sum of the uplink transmit powers of the carriers is limited.

In some embodiments, the terminal device limits the uplink transmit power of the first carrier and the uplink transmit power of the second carrier based on a single-carrier power limitation mode. This may mean that the terminal device individually limits the uplink transmit power of the first carrier to not exceed The directivity peak transmit power of the terminal equipment; and individually limiting the uplink transmit power of the second carrier to not exceed the directivity peak transmit power of the terminal equipment without limiting the uplink transmit power of the first carrier and the uplink transmit power of the second carrier The sum does not exceed the peak transmit power of the terminal equipment's directivity. Referring again to Figure 8, taking the directional peak transmit power as an example, the power limit based on a single carrier can mean that the terminal equipment can individually limit the uplink transmit power of CC1 in each direction to not exceed the max peak EIRP requirement, and the CC2 in each direction. The uplink transmit power cannot exceed the max peak EIRP requirement, without limiting the sum of the uplink transmit powers of CC1 and CC2 in each direction cannot exceed the max peak EIRP requirement.

In some embodiments, the terminal device may limit the uplink transmit power of the first carrier and the uplink transmit power of the second carrier based on a multi-carrier power limitation mode, or in other words, the power control of the uplink transmit power of the first carrier and The power control of the uplink transmit power of the second carrier is based on multi-carrier power limitation.

In some embodiments, multi-carrier-based power limitation may mean that the terminal device limits the maximum power of the sum of the uplink transmission power of the first carrier and the uplink transmission power of the second carrier, that is, limiting the uplink transmission of the first carrier. The sum of the power and the uplink transmit power of the second carrier does not exceed a certain limit, such as the limit of the directional peak transmit power. In other words, the sum of the uplink transmit power of the first carrier in all directions and the uplink transmit power of the second carrier in all directions does not exceed the max peak EIRP requirement.

In some embodiments, the terminal device may be a millimeter wave terminal device. Millimeter wave terminal equipment refers to terminal equipment that can operate in the millimeter wave frequency band. That is to say, the terminal equipment in the embodiment of the present application may be a high-power terminal equipment, which may operate in a high-frequency band, such as a millimeter wave band, or other high-frequency bands.

In some embodiments, the power control mode of the uplink transmit power of the first carrier and the uplink transmit power of the second carrier is determined based on the trigger condition. That is to say, under certain conditions, the terminal device may limit the uplink transmit power of the first carrier and the uplink transmit power of the second carrier based on the power limitation mode of a single carrier; under other conditions, the terminal device may limit the uplink transmit power of the first carrier based on The multi-carrier power limitation mode limits the uplink transmit power of the first carrier and the uplink transmit power of the second carrier.

The trigger condition of the power control mode can be associated with a variety of information, which is not limited in this application. Exemplarily, the triggering condition of the power control mode may be associated with one or more of the following information: the co-site relationship of the first carrier and the second carrier; and the beam direction of the first beam and the beam direction of the second beam. (Wherein, the first beam corresponds to the first carrier, and the second beam corresponds to the second carrier).

The triggering conditions of the power control mode may include triggering conditions based on power limitation of a single carrier and triggering conditions based on power limitation of multiple carriers.

In some embodiments, when the triggering condition of the power limitation based on a single carrier is associated with the co-site relationship of the first carrier and the second carrier, the triggering condition of the power limitation based on the single carrier may include: the first carrier and the second carrier. They are not related to the same site address.

When the first carrier and the second carrier do not share the same site address, it can be considered that the beam direction of the downlink transmission beam of the first carrier and the beam direction of the downlink transmission beam of the second carrier are different. Furthermore, it can be indirectly considered that the beam direction of the downlink receiving beam of the first carrier is different from the beam direction of the downlink receiving beam of the second carrier. It can further be considered that the beam direction of the uplink transmitting beam of the first carrier is different from the beam direction of the uplink transmitting beam of the second carrier. The direction is also different. In this case, it can be considered that the superposition effect between the uplink transmit power of the first carrier and the second carrier is weak. When the first carrier and the second carrier are limited based on the power limitation mode of a single carrier, both The superposition of the uplink transmit power will not have any impact on the human body.

In some embodiments, when the triggering condition of the power limitation based on a single carrier is associated with the beam direction of the first beam and the beam direction of the second beam, the triggering condition of the power limitation based on the single carrier may include one of the following conditions or Various: the beam direction of the first beam and the beam direction of the second beam are different; and the angle between the beam direction of the first beam and the beam direction of the second beam is greater than the first threshold (or the first threshold).

In some embodiments, the beam direction of the first beam and the beam direction of the second beam are different or the angle between them is greater than the first threshold, which may mean that the beam direction of the downlink transmission beam of the first carrier is different from the beam direction of the second carrier. The beam directions of the downlink transmission beams are different or the angle between them is greater than the first threshold.

In some embodiments, the beam direction of the first beam and the beam direction of the second beam are different or the angle between them is greater than the first threshold, which may mean that the beam direction of the downlink receiving beam of the first carrier is different from the beam direction of the second carrier. The beam directions of the downlink receiving beams are different or the angle between them is greater than the first threshold.

In some embodiments, the beam direction of the first beam and the beam direction of the second beam are different or the angle between them is greater than the first threshold, which may mean that the beam direction of the uplink transmission beam of the first carrier is different from the beam direction of the second carrier. The beam directions of the uplink transmission beams are different or the angle between them is greater than the first threshold.

When the beam direction of the first beam and the beam direction of the second beam are different, or the angle between the beam direction of the first beam and the beam direction of the second beam is greater than the first threshold, it can be considered that the first beam and the second beam are different. The superposition effect between the transmit powers of the two beams is weak.

The embodiment of the present application does not limit the method of determining the first threshold. In some embodiments, the first threshold is a predefined value. In some embodiments, the first threshold is a value configured or indicated by the network device to the terminal device. In some embodiments, the first threshold is a value determined autonomously by the terminal device.

The embodiment of the present application does not limit the value range of the first threshold. For example, the first threshold may be any value between greater than 0 and less than or equal to 180°. In some embodiments, for the safety of the human body, the value of the first threshold can be set slightly larger, for example, it can be set to any value between 60-180°, or it can be set to a value between 90-180°. Any value, etc.

In some embodiments, when the triggering condition for multi-carrier-based power limitation is associated with the co-site relationship of the first carrier and the second carrier, the triggering condition for multi-carrier-based power limitation may include: the first carrier and the second carrier It is a shared site relationship.

In some embodiments, when the triggering condition of the multi-carrier-based power limitation is associated with the beam direction of the first beam and the beam direction of the second beam, the triggering condition of the multi-carrier-based power limitation may include one of the following conditions or Multiple: the beam direction of the first beam and the beam direction of the second beam are the same; and the angle between the beam direction of the first beam and the beam direction of the second beam is less than or equal to the second threshold (or, second threshold) .

In some embodiments, the beam direction of the first beam and the beam direction of the second beam are the same or the angle between them is less than or equal to the second threshold, which may mean that the beam direction of the downlink transmission beam of the first carrier and the second carrier The beam directions of the downlink transmission beams are the same or the angle between them is less than or equal to the second threshold.

In some embodiments, the beam direction of the first beam and the beam direction of the second beam are the same or the angle between them is less than or equal to the second threshold, which may mean that the beam direction of the downlink receiving beam of the first carrier and the second carrier The beam directions of the downlink receiving beams are the same or the angle between them is less than or equal to the second threshold.

When the beam direction of the first beam and the beam direction of the second beam are the same, or the angle between the beam direction of the first beam and the beam direction of the second beam is less than or equal to the second threshold, it can be considered that the first beam and The superposition effect between the transmit power of the second beam is stronger.

In some embodiments, the values of the first threshold and the second threshold may be the same. In some embodiments, the values of the first threshold and the second threshold may also be different.

Regarding the determination method of the second threshold and the value range of the second threshold, reference may be made to the relevant description of the first threshold, which will not be described again here.

In some embodiments, the plurality of carriers also includes a third carrier. For example, when the network device has configured the first carrier and the second carrier to the terminal device, it configures a new third carrier to the terminal device. In this case, the power control mode of the uplink transmit power of the third carrier is jointly determined based on the first carrier and the second carrier, which may mainly include the following situations.

Case 1: Some or all of the first carrier and the second carrier have different site addresses from the third carrier. In this case, the power control mode of the uplink transmit power of some or all of the carriers and the uplink transmit power of the third carrier is a mode based on the power limitation of a single carrier. Except for the part or The power control mode of the uplink transmission power of the remaining carriers excluding all carriers and the uplink transmission power of the third carrier is a mode based on power limitation of multiple carriers.

For example, assuming that the first carrier, the second carrier, and the third carrier are not in a co-site relationship with each other, the first carrier, the second carrier, and the third carrier may all adopt single-carrier-based power limitation. mode. Or, assuming that the first carrier and the third carrier have a co-site relationship and the second carrier does not have a co-site relationship, the first carrier and the third carrier adopt a multi-carrier-based power limitation mode, and the second carrier adopts a multi-carrier-based power limitation mode. Single carrier power limited mode.

Case 2: The beam direction of part or all of the first beam and the second beam is different from the beam direction of the third beam, then the uplink transmission power of the carrier corresponding to this part or all of the beam is different from the uplink transmission power of the third carrier. The power control mode is a mode based on the power limitation of a single carrier. The power control of the uplink transmit power of the carrier corresponding to the remaining beams in the first beam and the second beam except for part or all of the beam and the uplink transmit power of the third carrier The mode is a mode based on multi-carrier power limitation. It should be understood that the third beam refers to the beam corresponding to the third carrier, and the meanings appearing later are consistent with this, and will not be described again.

For example, assuming that the first beam, the second beam, and the third beam all have different beam directions from each other, the first carrier, the second carrier, and the third carrier may all adopt a mode based on power limitation of a single carrier. Or, assuming that the beam directions of the first beam and the third beam are the same, and the beam directions of the second beam and the first beam (the third beam) are different, then the first carrier and the third carrier adopt a mode based on multi-carrier power limitation, The second carrier adopts a mode based on power limitation of a single carrier.

Case 3: If the angle between the beam direction of some or all of the first beam and the second beam and the beam direction of the third beam is greater than the first threshold, then the uplink transmit power of the carrier corresponding to the part or all of the beam The power control mode of the uplink transmit power of the third carrier is a mode based on the power limitation of a single carrier. The uplink transmit power of the carrier corresponding to the remaining beams in the first beam and the second beam except for part or all of the beam and the third carrier. The power control mode of the uplink transmit power of the three carriers is a mode based on power limitation of multiple carriers.

For example, assuming that the angles between the beam directions of the first beam, the second beam, and the third beam are all greater than the first threshold, the first carrier, the second carrier, and the third carrier may all adopt a single-carrier-based method. power limiting mode. Alternatively, assume that the angle between the beam directions of the first beam and the third beam is less than the first threshold, the angle between the beam directions of the second beam and the first beam is greater than the first threshold, and the angle between the second beam and the third beam is If the angle between the beam directions of the beams is greater than the first threshold, the first carrier and the third carrier adopt a power limitation mode based on multiple carriers, and the second carrier adopts a power limitation mode based on a single carrier.

In the following, with reference to Embodiment 1 to Embodiment 3, the terminal device determines the power control mode of multiple carriers based on trigger conditions in detail.

Embodiment 1: Co-site relationship based on the first carrier and the second carrier

In Embodiment 1, the power control mode of the terminal device may be determined based on the co-site relationship between the first carrier and the second carrier.

In some embodiments, the co-site relationship of multiple carriers is indicated by the network device. For example, the co-site relationship of the first carrier and the second carrier may be indicated by the network device. Optionally, the co-site relationship between the first carrier and the second carrier may be indicated by the network device corresponding to the serving cell where the terminal device is located. The network device corresponding to the serving cell where the terminal device is located may be a network device corresponding to the first carrier or a network device corresponding to the second carrier. This is not limited in the embodiments of the present application.

In some embodiments, the network device may indicate the co-site relationship of multiple carriers through a radio resource control (RRC) message, for example, through an RRC reconfiguration message. However, the embodiments of the present application are not limited to this. Alternatively, the network device may also use downlink control information (DCI) or media access control layer control element (medium access control control element, MAC CE) messages, etc. Other messages to indicate the co-site relationship of multiple carriers.

In some embodiments, the network device may indicate to the terminal device the co-site relationship between multiple carriers when configuring a new carrier to the terminal device.

Optionally, when configuring a new carrier to the terminal device, the network device may indicate to the terminal device the co-site relationship between the new carrier and the existing carrier. For example, when the network device configures a new secondary carrier to the terminal device, it may indicate the co-site relationship between the new secondary carrier and the primary carrier, or it may indicate the co-site relationship between the new secondary carrier and the existing secondary carrier, etc. Assume that the carriers configured by the terminal device include CC1 and CC2, then when the network device configures the new carrier CC3 to the terminal device, it can indicate the co-site relationship between CC3 and CC1 and CC2 respectively. As an example, the network device can indicate that the co-site relationship between CC3 and the configured carrier is {co-site address, non-co-site address} corresponding to {CC1, CC2} respectively, that is, CC3 and CC1 have a co-site address relationship. , CC3 and CC2 have different site addresses.

After receiving the co-site relationship of multiple carriers indicated by the network device, the terminal device can correspondingly determine the power control mode of the multiple carriers based on the co-site relationship of the multiple carriers (ie, adjust the transmission power control strategy of the terminal device).

In some embodiments, when multiple carriers have a co-site relationship, it can be considered that the triggering condition based on the power limit based on a single carrier is not met, but the triggering condition based on the power limit based on multiple carriers is met. In this case, the terminal device can limit the uplink transmit power of multiple carriers based on the multi-carrier power limitation mode, and limit the total uplink transmit power of multiple carriers. For example, the total uplink transmit power of multiple carriers follows a The total power class, or the total uplink transmit power of multiple carriers does not exceed a certain threshold.

In some embodiments, when multiple carriers are not in a co-site relationship, it can be considered that the triggering condition of the power limit based on a single carrier is met. In this case, the terminal device can limit the uplink transmit power of multiple carriers based on the power limit mode of a single carrier, and perform separate power limits on multiple carriers, such as following a separate power level, or each carrier's The uplink transmit power does not exceed a certain threshold.

The following is an illustrative description of how a terminal device determines the transmit power control mode of the terminal device based on the co-site relationship of multiple carriers in conjunction with several specific examples.

Example 1: The network equipment has configured the primary carrier CC1 and the secondary carrier CC2 to the terminal equipment, and the two carriers have a co-site relationship. On this basis, the network equipment configures the new secondary carrier CC3 to the terminal equipment, and configures the new secondary carrier CC3 to the terminal equipment. It indicates that the secondary carrier CC3 has a co-site relationship with the existing primary carrier CC1 and secondary carrier CC2. The co-site relationship between the secondary carrier CC3 and the existing carrier can be seen in Figure 12. After the terminal equipment receives that CC3 has a co-site relationship with the existing carriers CC1 and CC2, it limits CC1, CC2 and CC3 based on the multi-carrier power limitation mode, that is, it controls the total transmission of the terminal equipment on CC1, CC2 and CC3. The power meets the limits of the total power level. For example, if the total power level requires a max peak EIRP of 43dBm, then even if the transmit power of the terminal equipment on each CC can reach a peak EIRP of 43dBm, under this multi-carrier combination, the sum of its peak EIRPs still cannot exceed 43dBm.

Example 2: The network equipment has configured the primary carrier CC1 and the secondary carrier CC2 to the terminal equipment, and the two carriers have a co-site relationship. On this basis, the network equipment configures the new secondary carrier CC3 to the terminal equipment, and configures the new secondary carrier CC3 to the terminal equipment. It indicates that the auxiliary carrier CC3 does not have a co-site relationship with the existing main carrier CC1 and auxiliary carrier CC2. The co-site relationship between the auxiliary carrier CC3 and the existing carrier can be seen in Figure 13. After the terminal equipment receives that CC3 does not share a site address with the existing carriers CC1 and CC2, it restricts CC1 and CC2 based on the multi-carrier power restriction mode, and restricts CC3 based on the single-carrier power restriction mode, that is, The uplink transmit power of the terminal equipment on the CC1+CC2 carrier combination and the uplink transmit power on CC3 can be controlled separately. In other words, only a single CC1+CC2 carrier combination needs to meet the total power level limit, and CC3 needs to meet the individual power level limit. Just limit it. For example, the total power level requires a max peak EIRP of 43dBm. In this multi-carrier combination, the CC1+CC2 carrier combination is in a co-site relationship, so the sum of the peak EIRP of CC1+CC2 needs to be controlled not to exceed 43dBm. Since CC3 is different from other carriers, The carriers do not share the same site address, so the uplink transmit power of CC3 can be controlled individually, that is, the peak EIRP of CC3 cannot exceed 43dBm. At this time, it can be seen that the total transmit power of the three carriers exceeds 43dBm.

Example 3: The network equipment has configured the primary carrier CC1 and the secondary carrier CC2 to the terminal equipment, and the two carriers do not share the same site address. On this basis, the network equipment configures the new secondary carrier CC3 to the terminal equipment, and configures the new secondary carrier CC3 to the terminal equipment. The device indicates that the auxiliary carrier CC3 has a co-site relationship with some existing carriers. It is assumed that it has a co-site relationship with the main carrier CC1. The co-site relationship between the auxiliary carrier CC3 and the existing carriers can be seen in Figure 14. After the terminal equipment receives the co-site relationship between CC3 and the existing CC1 and CC2, it restricts CC1 and CC3 based on the multi-carrier power restriction mode, and restricts CC2 based on the single-carrier power restriction mode, that is, it can be used respectively. Control the uplink transmit power of the terminal equipment on the CC1+CC3 carrier combination and the uplink transmit power on CC2. In other words, only the separate CC1+CC3 carrier combination needs to meet the restrictions of the total power level, and CC2 needs to meet the restrictions of the individual power levels. Can. For example, the total power level requires a max peak EIRP of 43dBm. In this multi-carrier combination, the CC1+CC3 carrier combination is in a co-site relationship, so the sum of the peak EIRP of CC1+CC3 needs to be controlled not to exceed 43dBm. Since CC2 is different from other carriers, The carriers do not share the same site address, so the uplink transmit power of CC2 can be controlled individually, that is, the peak EIRP of CC2 cannot exceed 43dBm. At this time, it can be seen that the total transmit power of the three carriers exceeds 43dBm.

The terminal equipment determines the transmit power control mode of the terminal equipment based on the co-site relationship of multiple carriers. When the carriers have a co-site relationship, the power limitation mode based on multiple carriers is implemented. When the carriers do not have a co-site relationship, , implement a mode based on single carrier power limitation. This method is used to determine the transmission power control mode of the terminal device, which is simple to implement and easy to operate.

Embodiment 2: Based on the downlink beam direction of the first beam and the downlink beam direction of the second beam

In the second embodiment, the terminal may be determined based on whether the downlink beam direction of the first beam and the downlink beam direction of the second beam are the same, or the angle between the downlink beam direction of the first beam and the downlink beam direction of the second beam. The power control mode of the device.

Optionally, it can be considered that in Embodiment 2, the co-site relationship between multiple carriers can be determined based on the downlink beam direction of the first beam and the downlink beam direction of the second beam (the co-site relationship here is only used as an intermediate The measurement is used to facilitate understanding of the power control of the terminal device. In practice, the terminal device only needs to directly derive the power control mode based on the downlink beam direction of the first beam and the downlink beam direction of the second beam). It should be understood that the embodiment of the present application will not determine the co-site relationship between carriers based on the downlink beam direction of the first beam and the downlink beam direction of the second beam, and then determine the co-site relationship between carriers based on the determined co-site relationship. Determining the power control mode of the terminal equipment is based on the fact that the downlink beam direction of the first beam and the downlink beam direction of the second beam are the same, which does not necessarily mean that the first carrier and the second carrier have a co-site relationship, and the downlink direction of the first beam The fact that the beam direction is different from the downlink beam direction of the second beam does not necessarily mean that the first carrier and the second carrier do not share the same site address.

In some embodiments, the first beam refers to the downlink transmission beam of the first carrier, and the second beam refers to the downlink transmission beam of the second carrier. In this case, the terminal device may determine the transmission power control mode of the terminal device based on the beam direction of the downlink transmission beam of the first carrier and the beam direction of the downlink transmission beam of the second carrier. The following takes the first carrier and the second carrier as an example to introduce the transmission power control mode of the terminal device based on the downlink transmission beam of the first carrier and the downlink transmission beam of the second carrier. The situation with more than two carriers is similar. No longer.

In some embodiments, the beam direction of the first beam and the beam direction of the second beam are determined based on the beam information of the downlink transmit beam sent by the network device.

The embodiments of this application do not limit the content of the beam information of the downlink transmission beam sent by the network device. For example, the beam information of the downlink transmission beam may include one or more of the following information: the beam identification of the downlink transmission beam, and the beam direction of the downlink transmission beam. In addition to the information listed in the embodiments of this application, the beam information of the downlink transmission beam may also include other information, which is not limited in the embodiments of this application.

As an implementation manner, the beam information of the downlink transmit beam includes the beam identifier of the downlink transmit beam and the beam direction of the downlink transmit beam. Referring to Figure 15, in this case, the network device can inform the terminal device of the beam information (beam identification + beam direction) of the downlink transmit beam, so that after the terminal device measures the downlink receive beam, it can obtain measurements based on the beam information of the downlink transmit beam. Obtained angle information between downlink receiving beams. In other words, the angle information between the downlink receiving beams measured by the terminal equipment can be directly obtained from the beam direction information of the downlink transmitting beam of the network equipment.

As another implementation manner, the beam information of the downlink transmit beam includes the beam identifier of the downlink transmit beam, but does not include the beam direction of the downlink transmit beam. In this case, after the network device notifies the terminal device of the beam information (beam identifier) of the downlink transmit beam, and after the terminal device measures the downlink receive beam, it can inform the network device of the measured beam identifier of the downlink receive beam, and the network device Determine the angle information between downlink receiving beams and inform the terminal equipment of the angle information.

The embodiments of this application do not limit the method by which the terminal equipment measures the downlink receiving beam. For example, the terminal device may determine the optimal downlink beam of each carrier by measuring the downlink beam strength of each carrier, and use the optimal downlink beam of each carrier as the downlink receiving beam.

When the angle between the downlink receiving beams measured by the terminal equipment is less than or equal to the second threshold, it can be considered that the triggering condition of the multi-carrier-based power limitation is met. In this case, the terminal device may limit the uplink transmit power of multiple carriers based on the multi-carrier power limitation mode.

When the angle between the downlink receiving beams measured by the terminal equipment is greater than the first threshold (for example, the same value as the second threshold), it can be considered that the triggering condition of the single-carrier-based power limit is met. In this case, the terminal device may limit the uplink transmit power of multiple carriers based on the power limitation mode of a single carrier.

In some embodiments, the first beam refers to the downlink receiving beam of the first carrier, and the second beam refers to the downlink receiving beam of the second carrier. In this case, the terminal device may determine the transmit power control mode of the terminal device based on the beam direction of the downlink receive beam of the first carrier and the beam direction of the downlink receive beam of the second carrier.

Referring to Figure 16, as an implementation method, the terminal device can select the optimal receiving beam of the first carrier as the downlink receiving beam of the first carrier and the optimal receiving beam of the second carrier by measuring the downlink signal strength of each carrier. The beam serves as the downlink receiving beam of the second carrier, and the power control mode of the terminal device is determined by the angle between the downlink receiving beam of the first carrier and the downlink receiving beam of the second carrier.

The terminal equipment adjusts the transmission power control mode of the terminal equipment based on the downlink beam direction of the carrier. Compared with adjusting based on the co-site relationship of the carrier, using this method to determine the transmission power control mode of the terminal equipment is more accurate. However, The implementation complexity will also increase relatively.

Embodiment 3: Based on the uplink beam direction of the first beam and the uplink beam direction of the second beam

It is different from the indirect method used in Embodiment 1 and Embodiment 2 to determine the direction of the uplink transmit beam of the carrier (that is, it is considered that the downlink transmit beam of the network device comes from different directions, or the downlink receive beam of the terminal device has different beam directions. The direction of the uplink transmit beam will also be different). Embodiment 3 adopts a more direct method to determine the transmit power control mode of the terminal device directly based on the beam direction of the uplink transmit beam of the terminal device.

In some embodiments, the first beam refers to the uplink transmission beam of the first carrier, and the second beam refers to the uplink transmission beam of the second carrier. In this case, the terminal device may determine the transmission power control mode of the terminal device based on the beam direction of the uplink transmission beam of the first carrier and the beam direction of the uplink transmission beam of the second carrier.

The embodiment of the present application does not limit the method for determining the uplink transmission beam of the terminal device. For example, the terminal device can select the optimal receiving beam of the first carrier based on the measurement of the downlink signal of the first carrier, and use the transmitting beam corresponding to the optimal receiving beam as the uplink transmitting beam of the first carrier; similarly, The terminal device may select the optimal receiving beam of the second carrier based on the measurement of the downlink signal of the second carrier, and use the transmitting beam corresponding to the optimal receiving beam as the uplink transmitting beam of the second carrier.

In some embodiments, the uplink transmit beam determined by the terminal device may be the same as the optimal receive beam measured by the terminal device. In some embodiments, the uplink transmit beam determined by the terminal device may be different from the optimal receive beam measured by the terminal device. For example, in order to avoid harm to the human body caused by the uplink transmit beam of the terminal device, a beam different from the optimal receive beam may be used. As the uplink transmit beam of the terminal equipment.

When the angle between the uplink transmission beams determined by the terminal device is less than or equal to the second threshold, it can be considered that the triggering condition of the multi-carrier-based power limitation is met. In this case, the terminal device may limit the uplink transmit power of multiple carriers based on the multi-carrier power limitation mode.

When the angle between the uplink transmission beams determined by the terminal equipment is greater than the first threshold, it can be considered that the triggering condition of the power limit based on the single carrier is met. In this case, the terminal device may limit the uplink transmit power of multiple carriers based on the power limitation mode of a single carrier.

Referring to Figure 17, after the terminal device selects the uplink transmit beam of CC1 and the uplink transmit beam of CC2, the uplink transmit beam of CC1 points to the network device 110a, and the uplink transmit beam of CC2 points to the network device 110b. As can be seen from Figure 17, the angle between the uplink transmit beam of CC1 and the uplink transmit beam of CC2 is large, and the superposition effect between the transmit powers corresponding to the uplink transmit beams will be very weak. At this time, it can be based on The single-carrier power limitation mode limits CC1 and CC2.

The terminal equipment adjusts the transmission power control mode of the terminal equipment based on the beam direction of the carrier's uplink transmission beam. On the one hand, the determined beam direction is more direct and more accurate. On the other hand, it can also take the initiative when the carrier's uplink transmission beam points to the human body. Changing the direction of the carrier's uplink transmission beam is more consistent with the actual situation.

In some embodiments, the power control mode is determined based on one of the following: terminal device autonomous determination, network device assisted determination, and network device determination.

Method 1: The terminal device determines independently: The terminal device can independently decide to adopt a multi-carrier-based power limitation mode based on the co-site relationship between multiple carriers or the relationship between the beam directions of the beams corresponding to multiple carriers. Still adopt the mode based on single carrier power limitation.

Taking the first carrier and the second carrier as an example, if the first carrier and the second carrier have a co-site relationship, the terminal device can independently decide to adopt a mode based on multi-carrier power limitation; if the first carrier and the second carrier are If there is no shared site address relationship, the terminal equipment can independently decide to adopt a mode based on single-carrier power limitation.

Continuing to take the first carrier and the second carrier as an example, if the angle between the beam direction of the uplink transmission beam of the first carrier and the beam direction of the uplink transmission beam of the second carrier is less than the first threshold, the terminal device can decide independently A mode based on multi-carrier power limitation is adopted; if the angle between the beam direction of the uplink transmit beam of the first carrier and the beam direction of the uplink transmit beam of the second carrier is greater than the first threshold, the terminal device can independently decide to adopt the mode based on multi-carrier power limitation. Single carrier power limited mode.

Method 2: Assisted determination by network equipment: On the basis of the network equipment providing auxiliary information to the terminal equipment, the terminal equipment determines whether to adopt the mode of power limitation based on multi-carriers or the mode of power limitation based on single carrier.

In some embodiments, the network device providing the auxiliary information to the terminal device may mean that the network device indicates to the terminal device the co-site relationship of multiple carriers. Taking the first carrier and the second carrier as an example, the network device may indicate to the terminal device the co-site relationship between the first carrier and the second carrier. In the case where the first carrier and the second carrier have a co-site relationship, the terminal device may determine to adopt a multi-carrier-based power limitation mode. In the case where the first carrier and the second carrier do not share the same site address, the terminal device may determine to adopt a mode based on power limitation of a single carrier.

In some embodiments, the network device providing auxiliary information to the terminal device may mean that the network device provides the terminal device with a threshold value of the included angle (the first threshold in the embodiment of this application). Taking the first carrier and the second carrier as an example, the network device may indicate the value of the first threshold to the terminal device. The terminal device determines the beam direction of the beam corresponding to the first carrier (for example, the beam direction of the downlink transmission beam of the first carrier) and the beam direction of the beam corresponding to the second carrier (for example, the beam direction of the downlink transmission beam of the first carrier). When the angle between them is less than the first threshold, it is determined to adopt the mode of power limitation based on multi-carriers. When the terminal device determines that the angle between the beam direction of the beam corresponding to the first carrier and the beam direction of the beam corresponding to the second carrier is greater than the first threshold, it determines to adopt the mode of power limitation based on a single carrier.

Method 3: Network device determination: The network device can determine whether to adopt a multi-carrier-based power limitation mode or a single-carrier-based power limitation mode based on the information reported by the terminal device.

In some embodiments, the information reported by the terminal device may refer to the angle information of the beams measured by the terminal device, such as the angle information between the downlink receiving beams corresponding to multiple carriers measured by the terminal device or determined by the terminal device. Angle information between uplink transmission beams corresponding to multiple carriers. Taking the first carrier and the second carrier as an example, after receiving the angle information between the beam direction of the downlink receive beam of the first carrier and the beam direction of the downlink receive beam of the second carrier reported by the terminal device, the network device can Directly based on the angle information, it is determined whether to adopt the mode of power limitation based on multi-carrier or the mode of power limitation based on single carrier; or the network device receives the beam direction of the uplink transmission beam of the first carrier reported by the terminal device and the second After the angle information between the beam directions of the uplink transmission beams of the carriers is obtained, it can be directly determined based on the angle information whether to adopt the mode of power limitation based on multiple carriers or the mode of power limitation based on a single carrier.

In some embodiments, the information reported by the terminal device may refer to the beam information of the optimal receiving beam reported by the terminal device. Taking the first carrier and the second carrier as an example, the terminal device can combine the measured beam information (such as beam identification and/or beam direction) of the optimal receiving beam corresponding to the first carrier with the optimal receiving beam corresponding to the second carrier. The beam information is reported to the network device. The network device determines the angle information between the optimal receiving beam corresponding to the first carrier and the optimal receiving beam corresponding to the second carrier based on the received beam information, and determines the method to use based on the angle information. The mode of power limitation based on multi-carriers is still the mode of power limitation based on single carrier.

It should be understood that the beam corresponding to the carrier mentioned in the embodiment of this application may refer to the downlink transmit beam of the carrier, the downlink receive beam of the carrier, or the uplink transmit beam of the carrier.

The previous article combined with the accompanying drawings introduces how the terminal equipment determines the transmit power control mode of the terminal equipment based on trigger conditions in a multi-carrier communication scenario. That is, in a multi-carrier scenario, the terminal equipment can determine the transmit power control mode of the terminal equipment based on a single trigger condition if certain conditions are met. The carrier power limitation mode limits the first carrier and the second carrier. It should be understood that if the terminal device can limit the first carrier and the second carrier based on the power limitation mode of a single carrier, the terminal device can be considered to have the capability of power limitation based on a single carrier.

Continuing to refer to Figure 18, in some embodiments, the method may further include step S1830. In step S1830, the network device sends second information to the terminal device. The second information is used to instruct the terminal device to enable/disable the first capability. In other words, the network device may send the second information to the terminal device to activate the first capability, that is, the capability of activating power limitation based on a single carrier; or the network device may send the second information to the terminal device to deactivate the first capability.

The embodiment of the present application does not limit the carrying method of the second information. For example, the second information may be carried in one or more of an RRC message, a MAC message or a DCI message.

In some embodiments, before step S1840, step S1835 may also be included. In step S1835, the terminal device may send a second request message to the network device, where the second request message is used to request the network device to send auxiliary information.

It should be understood that the steps shown in Figure 18 are only illustrative, and each step may be an optional step. Alternatively, multiple messages (corresponding to multiple steps in Figure 18) may be combined into one message in practice, which is not limited in the embodiments of the present application.
