All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Fig. 1 is a schematic diagram of an application scenario according to an embodiment of the present application.

As shown in fig. 1, communication system 100 may include a terminal device 110 and a network device 120. Network device 120 may communicate with terminal device 110 over the air interface. Multi-service transmission is supported between terminal device 110 and network device 120.

It should be understood that the present embodiments are illustrated by way of example only with respect to communication system 100, but the present embodiments are not limited thereto. That is, the technical solution of the embodiment of the present application may be applied to various communication systems, for example: long term evolution (Long Term Evolution, LTE) system, LTE time division duplex (Time Division Duplex, TDD), universal mobile telecommunications system (Universal Mobile Telecommunication System, UMTS), 5G communication system (also referred to as New Radio (NR) communication system), or future communication system, etc.

Taking the communication system 100 shown in fig. 1 as an example, the communication device may include a network device 120 and a terminal device 110 with communication functions, where the network device 120 and the terminal device 110 may be the devices described above, and are not described herein again; the communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in this embodiment of the present application.

It should be understood that the terms "system" and "network" are used interchangeably herein. The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

In the 5G NR system, a millimeter wave working frequency band is introduced, and the millimeter wave working frequency is generally above 10 GHz.

In order to facilitate understanding of the solution of the present application, the following description will explain the related content of the millimeter wave spectrum.

As shown in fig. 2, n257, n258, n259, n260, n261, and the like are millimeter wave band numbers. Wherein, the frequency spectrum range of n257 is 26.5 GHz-29.5 GHz, the frequency spectrum range of n258 is 24.25 GHz-27.5 GHz, the frequency spectrum range of n259 is 39.5 GHz-43.5 GHz, the frequency spectrum range of n260 is 37 GHz-40 GHz, and the frequency spectrum range of n261 is 27.5 GHz-28.35 GHz.

The coverage of electromagnetic wave signals is limited due to the very large spatial propagation loss of electromagnetic waves in the millimeter wave band. In order to overcome the large space loss, the terminal generally adopts an antenna array formed by a plurality of antenna elements in the millimeter wave frequency band to form narrow wave beams for transmitting and receiving signals, and the narrow wave beams have relatively strong directivity. Fig. 3 is an example of a beam-based communication manner of a 5G millimeter wave terminal provided in an embodiment of the present application. As shown in fig. 3, communication is performed between a base station and a terminal by a narrow beam having relatively strong directivity.

When a terminal operates in a plurality of frequency bands (e.g., band (Band) a and Band (Band) B) at the same time, the terminal needs to perform beamforming in the plurality of frequency bands at the same time to communicate with a base station. From the terminal implementation point of view, there are two cases:

One case is: the terminal has only one group of transmitting/receiving antenna units, at this time, only one set of beamforming factors can be used for beamforming the frequency band at the same time, that is, only one frequency band can be beamformed according to the beamforming factor corresponding to the one frequency band, and the other frequency band can be shaped according to the same beamforming factor and generate a beam. Typically, such terminals may be referred to as terminals having common beam management (Common Beam Management, CBM) capabilities or CBM capable terminals. FIG. 4 is an example of a CBM capability terminal provided by an embodiment of the present application. As shown in fig. 4, the CBM capable terminal has only one set of transmit/receive antenna units, i.e. there is a set of phase shifters and antenna arrays corresponding to the transmit/receive antenna units, and both the frequency band a and the frequency band B can perform beamforming through the set of transmit/receive antenna units and communicate with the base station, but only one beamforming parameter corresponding to one frequency band can be used at the same time to perform beamforming on the frequency band a and the frequency band B.

Another case is: the terminal has two (or more) groups of transmitting/receiving antenna units, and can respectively perform beam forming by adopting respective beam forming factors for two frequency bands at the same time to generate two (or more) independent beams. Typically, such terminals may be referred to as terminals having independent beam management capabilities (Independent Beam Management, IBM) or IBM capable terminals. FIG. 5 is an example of an IBM capability terminal provided by an embodiment of the present application. As shown in fig. 5, the IBM capable terminal has two sets of transmit/receive antenna elements, i.e., each set of transmit/receive antenna elements has its own phase shifter and antenna array; the frequency band A and the frequency band B carry out wave beam forming through a group of transmitting/receiving antenna units respectively and communicate with a base station; at the same time, the beamforming factor of the frequency band A can be used for beamforming for the frequency band A, and the beamforming factor of the frequency band B can be used for beamforming for the frequency band B, so that two (or more) independent beams are finally generated.

For the CBM capable terminal, since different frequency bands share the same group of transmitting/receiving antenna units, beam forming can only be performed according to one frequency band at the same time, that is, the same time only can accurately direct the beam of one frequency band to one direction, so that in most cases, the CBM capable terminal working in the frequency band a and the frequency band B can only be in a cell of a co-sited scene, and the co-sited scene can also be called a multi-frequency band co-beam scene. Fig. 6 is an example of a co-sited scenario provided by an embodiment of the present application. As shown in fig. 6, at the same time, the frequency band a and the frequency band B communicate with the base station 1 and the base station 2, respectively, through one common beam.

For IBM capable terminals, two or more independent beams may be generated at the same time, that is, the terminal may direct the beams in different directions at the same time, so that the IBM capable terminals operating in frequency band a and frequency band B simultaneously may be in a cell not sharing a site scene, which may also be referred to as a multi-band independent beam scene. Fig. 7 is an example of a non-co-sited scenario provided by an embodiment of the present application. As shown in fig. 7, at the same time, the frequency band a and the frequency band B communicate with the base station 1 and the base station 2 respectively through respective independent beams.

In general, IBM capable terminals have higher flexibility and can operate in different base station deployment scenarios, while CBM capable terminals are more limited in application scenarios in the network. However, IBM-capable terminals are more complex, costly and power consuming to implement than CBM-capable terminals due to the need to have multiple transmit/receive antenna elements from a terminal implementation perspective. Therefore, in practical networks, the terminal mostly takes comprehensive consideration in terms of complexity, cost, power consumption, flexibility, and the like, and selects different implementation manners.

In order to facilitate understanding of the scheme of the present application, a scheme of configuring transmission power by the terminal device in a single band will be described below.

For a single band, the maximum transmit power of the terminal device is limited by parameters such as maximum peak effective omni-directional radiated power (max peak Effective Isotropic Radiated Power, EIRP), maximum total radiated power (max Total Radiated Power, max TRP), minimum peak transmitted power (min peak EIRP), and spherical coverage (spherical coverage). The effective omni-directional radiation power (Effective Isotropic Radiated Power, EIRP) is also referred to as equivalent omni-directional radiation power (Equivalent Isotropic Radiated Power, EIRP). For example, the EIRP of a transmitting device may be the power radiated by the receiving and transmitting antennas in the direction of the beam central axis, i.e. the product of the power supplied by the radio transmitter to the antenna and the absolute gain of the antenna in a given direction may be used as an indicator for characterizing the transmitting capability of the transmitting end. The total radiated power (Total Radiated Power, TRP) can be obtained by integrating and averaging the transmitted power of the whole radiating sphere, and is used for reflecting the transmitted power condition of the whole machine, and is related to the transmitted power of the device under the conduction condition and the radiation performance of the antenna.

As shown in fig. 8, a terminal may generate multiple beams in a certain frequency band (usually only one beam is working at the same time), and the requirements on the maximum transmission power are as follows:

1. in order to avoid interference to other terminals in the communication direction, the maximum power allowed to transmit by the terminal in the maximum transmit power direction (assumed to be Beam (Beam) 1) cannot exceed max peak EIRP, i.e. peak EIRP ₁ And not more than max Peak EIRP. Since the peak EIRP of Beam1 is larger than that of other beams, this means that other beams will also meet the max peak EIRP requirement. Alternatively, the max peak EIRP may come from regulatory requirements of a government regulatory agency.

2. In order to avoid interference to terminals in other directions, it is required that the sum of the radiation powers of the radiation beams of the terminals in all directions cannot exceed max TRP, and assuming that the beam with the largest radiation power in all directions is beam 2, the sum TRP of the radiation powers of beam 2 in all directions ₂ And less than or equal to max TRP. Since the total radiated power TRP of beam 2 is larger than the other beams, this means that the other beams will also meet the requirements of max TRP. Alternatively, the index max TRP may come from regulatory requirements of a government regulatory agency.

3. In order to ensure uplink coverage capability of the terminal, the maximum power transmitted by the terminal in the maximum transmit power direction (assumed to be Beam 1) should at least meet the requirement of min peak EIRP.

4. To ensure mobility and uplink coverage for the terminal, a statistical curve of peak transmit power in all directions should be required to meet the spherical coverage (spherical coverage) requirement, i.e., the peak EIRP for a certain percentage over the cumulative distribution function (cumulative distribution function, CDF) curve should be above a threshold. Fig. 9 is an example of spherical coverage requirements provided by an embodiment of the present application. As shown in fig. 9, the peak EIRP (i.e., 11.5) corresponding to 50% on the CDF curve should be above the threshold.

As described above, with the increase of the capabilities of the terminals, it is possible for both CBM capable terminals and IBM capable terminals to generate multiple beams on multiple frequency bands at the same time, and there is currently only a scheme in which the terminal device configures the transmit power in a single frequency band. However, since the multiple beams generate gains, if the transmission power of the terminal device in the multiple frequency bands is configured by using the scheme of configuring the transmission power of the terminal device in the single frequency band, the configuration accuracy of the transmission power may not meet the requirement. For example, how to perform transmit power configuration of a terminal when a network configures the terminal to operate on multiple frequency bands simultaneously, so as to meet the requirement of multi-band coverage and interference reduction simultaneously, is still to be studied, i.e. further improvement of a power configuration scheme of the terminal is needed in the art. According to the method and the terminal equipment, the maximum transmitting power of the terminal equipment is configured through analysis of the power interaction principle under the multi-band simultaneous working scene of the terminal, namely, the method and the terminal equipment for configuring the transmitting power are provided, the multi-band power configuration scheme of the terminal equipment is perfected, the transmitting power of the millimeter wave terminal can meet the requirement of regulations under the condition of multi-band parallel transmission, and uplink coverage is ensured.

As described above, in the millimeter wave band in the NR system, the terminal generally uses beamforming to concentrate the transmission power, so as to overcome large propagation loss and improve uplink and downlink coverage, and at the same time, it needs to ensure that the transmission power of the terminal cannot be too high, so as to avoid interference to the terminal in other directions. Thereby introducing maximum peak EIRP, maximum TRP, minimum peak EIRP, and sphere coverage, etc., to constrain power.

In this application, when the terminal configures multi-band simultaneous transmission such as carrier aggregation (Carrier Aggregation, CA) or Dual Connection (DC), its transmission power will increase, and it needs to be considered how to ensure that the terminal meets the regulatory requirements such as maximum peak EIRP, maximum TRP, minimum peak EIRP, and spherical coverage. In some embodiments, the maximum peak EIRP, the maximum TRP, or the minimum peak EIRP may be required separately per frequency band, i.e., the terminal need only perform power configuration per single frequency band requirement on each frequency band. In some embodiments, the maximum peak EIRP and/or the minimum peak EIRP may be in accordance with the overall requirements of the terminal, i.e., the terminal needs to comprehensively consider the power of all the simultaneously transmitted frequency bands in the same direction and make it meet the maximum peak EIRP and/or the minimum peak EIRP. In some embodiments, the maximum TRP may be in accordance with the overall requirements of the terminal, i.e., the terminal needs to ensure that the total radiated power of the simultaneously transmitted frequency bands does not exceed the maximum TRP.

Fig. 10 is a schematic flowchart of a method 200 for configuring transmit power according to an embodiment of the present application, where the method 200 may be performed by a terminal device, for example, a terminal device as shown in fig. 1, and further, a millimeter wave terminal.

As shown in fig. 10, the method 200 may include some or all of the following:

s210, under the condition that a plurality of frequency bands are transmitted in parallel, configuring the transmitting power of the frequency bands to meet the transmitting power requirement.

For example, the terminal device may configure the transmission power of the multiple frequency bands for the terminal device to meet the transmission power requirement based on the scenario of parallel transmission of the multiple frequency bands. Specifically, the terminal device can ensure that the terminal meets the legal requirements of maximum peak EIRP, maximum TRP, minimum peak EIRP, spherical coverage and the like through analyzing the scenes of parallel transmission of the plurality of frequency bands. For example, by analyzing the scenario of parallel transmission of the multiple frequency bands, the power of all the frequency bands transmitted simultaneously by the terminal device in the same direction can be ensured, and the maximum peak EIRP and/or the minimum peak EIRP can be satisfied. Based on the method, the terminal equipment meets the uplink coverage requirement, and meanwhile interference to other users is avoided.

In some embodiments, the S210 may include:

and configuring the total transmitting power of the frequency bands in the same direction to be smaller than or equal to the maximum peak effective omni-directional transmitting power EIRP, and/or configuring the total transmitting power of the frequency bands in the same direction to be larger than or equal to the minimum peak EIRP.

In other words, the maximum peak EIRP may be configured in accordance with the overall requirements of the terminal, i.e. the power for peak EIRP of the terminal device that has a great relationship with directionality.

In some embodiments, the method 200 may further comprise:

determining the sum of the first peak EIRP and at least one first EIRP as the total transmission power of the frequency bands in the same direction;

the first peak EIRP is a peak EIRP of a first beam on a first frequency band of the plurality of frequency bands, the first beam is a beam formed by performing beam forming through a beam forming factor of the first frequency band, and the at least one first EIRP includes transmission powers of beams on the plurality of frequency bands except for the first beam in the direction of the first peak EIRP.

In some implementations, the method 200 may further include:

the at least one first EIRP is determined.

In some implementations, determining at least one first beam corresponding to the first frequency band; and determining the transmission power of the at least one first beam in the first peak EIRP direction as the at least one first EIRP. Optionally, the at least one first beam includes a beam formed by respectively performing beam forming on at least one frequency band except the first frequency band in the plurality of frequency bands by using a beam forming factor of the first frequency band. Optionally, the method is applied to a co-sited scenario or a non-co-sited scenario. Alternatively, the method is applied to a common beam management CBM capable terminal.

The scheme of configuring transmit power with maximum peak rate EIRP in a co-sited deployment and non-co-sited deployment with CBM capable terminals is described below in connection with specific embodiments.

Example 1:

FIG. 11 is a CBM capable of providing an embodiment of the present applicationExamples of transmit power of a force terminal in different network scenarios. As shown in fig. 11, for the CBM capable terminal, since the same beamforming factor is adopted for the two frequency bands, it is assumed that the beamforming factor is obtained based on the frequency band 1, so that the beam 1 of the frequency band 1 can accurately point to the target base station 1, and the beam of the frequency band 2 has a directional deviation from the direction of the target base station. FIG. 12 is an example of CBM capable terminal maximum transmit power under different deployment scenarios provided by embodiments of the present application. As shown in fig. 12, the maximum transmission power (EIRP) of a terminal at the time of concurrence of two frequency bands is the peak EIRP, both in the case of co-sited deployment and in the case of non-co-sited deployment ₁ +EIRP ₃ Or peak EIRP ₂ +EIRP ₄ . Therefore, peak EIRP should be considered or determined in meeting the maximum peak EIRP indicator ₁ +EIRP ₃ Peak EIRP ₂ +EIRP ₄ That is, the problem in implementing the present solution is how to obtain the EIRP ₃ EIRP (EIRP) ₄ 。

Wherein, EIRP ₃ Is a beam ₂ At peak EIRP ₁ Power strength in direction, and EIRP ₃ Peak EIRP less than or equal to ₂ . Similarly, EIRP ₄ Is a beam ₁ At peak EIRP ₂ Power strength in direction, and EIRP ₄ Peak EIRP less than or equal to ₁ . In some embodiments of the present application, EIRP ₃ And EIRP ₄ The acquisition of (a) may be obtained by one of the following means:

in general, a terminal can only generate a limited number of beams, and can determine which beam is specifically used for transmitting and receiving by measuring the incoming wave direction, thereby determining that the peak EIRP needs to be considered ₁ Whether the peak EIRP needs to be considered ₂ . Assume that peak EIRP needs to be considered ₁ I.e. the beam forming factor of the CBM capable terminal is the beam forming factor corresponding to the frequency band 1, i.e. the beam is obtained by the beam forming factor corresponding to the frequency band 1 ₁ At the same time, the beam forming factor is applied to the frequency band 2 to obtain the corresponding beam ₂ It can be found that the beams of band 1 and band 2 have a one-to-one correspondence. By being in beam ₁ Beam in the peak direction of (a) ₂ The emission power (EIRP) can obtain the corresponding EIRP ₃ I.e. beam ₂ In the beam ₁ Antenna gain value in the peak direction of (a). By the same token, by beam ₂ Beam in the peak direction of (a) ₁ Transmitting power to obtain corresponding EIRP ₄ I.e. beam ₁ In the beam ₂ Antenna gain value in the peak direction of (a). The following is an exemplary illustration in conjunction with table 1.

TABLE 1

As shown in table 1, when the network configuration terminal transmits in both frequency band 1 and frequency band 2, the terminal should configure the beam compared to the scheme of configuring the transmission power of the terminal device in a single frequency band ₁ Sum beam ₂ To ensure peak EIRP ₁ +EIRP ₃ Maximum peak value EIRP less than or equal to the peak value EIRP ₂ +EIRP ₄ And the maximum peak value EIRP is less than or equal to.

Of course, the following modes can be obtained by simplifying the above modes:

by beam matching ₁ Sum beam ₂ The calibration of the peak EIRP of (c) may simplify the corresponding transmit power constraints. The following is an exemplary illustration in conjunction with table 2.

TABLE 2

As shown in table 2, when the network configures the transmission power of the band 1 and the band 2 to transmit simultaneously, compared with the scheme of configuring the transmission power of the terminal device in the single bandThe terminal should configure the total transmit power of the transmit beam on band 1 and the transmit beam on band 2 to ensure peak EIRP ₁ +peak EIRP ₂ And the maximum peak value EIRP is less than or equal to.

In other implementations, at least one second beam employed by at least one of the plurality of frequency bands other than the first frequency band is determined; and determining the transmission power of the at least one second beam in the direction of the first peak EIRP as the at least one first EIRP. Optionally, the at least one second beam includes a beam formed by respectively performing beam forming on the at least one frequency band by using at least one beam forming factor, where the at least one beam forming factor corresponds to the at least one frequency band one to one. Alternatively, the method is applied to non-co-sited scenarios. Alternatively, the method is applied to an independent beam management IBM capable terminal.

The scheme of configuring transmit power with maximum peak rate EIRP in both co-sited deployments and non-co-sited deployments of IBM capable terminals is described below in connection with specific embodiments.

Example 2:

fig. 13 is an example of transmit power of an IBM capable terminal provided by an embodiment of the present application under different network scenarios. As shown in fig. 13, for the IBM capable terminal, since two frequency bands can employ independent beamforming factors, and the beamforming factors are obtained based on the corresponding base stations, both beams can be accurately directed to the target base station. FIG. 14 is an example of IBM capable terminals maximum transmit power under different deployment scenarios provided by embodiments of the present application. As shown in fig. 14, since IBM capable terminals have differently directed beams in the case of co-sited deployments and in the case of non-co-sited deployments, it is necessary to determine different configuration requirements based on different scenarios. Specifically, under the co-station deployment condition, the maximum emission power (EIRP) of the IBM capability terminal in the concurrence of two frequency bands is peak value EIRP1+ peak value EIRP2, and the corresponding requirement satisfies that the peak value EIRP1+ peak value EIRP2 is less than or equal to the maximum peak value EIRP; under the condition of non-co-station deployment, the maximum emission power (EIRP) when two frequency bands are concurrent is peak value EIRP1+EIRP3 or peak value EIRP2+EIRP4, and the peak value EIRP1+EIRP3 is less than or equal to the maximum peak value EIRP and the peak value EIRP2+EIRP4 is less than or equal to the maximum peak value EIRP.

Wherein, EIRP ₃ Is a beam ₂ At peak EIRP ₁ Power strength in direction, and EIRP ₃ Peak EIRP less than or equal to ₂ . Similarly, EIRP ₄ Is a beam ₁ At peak EIRP ₂ Power strength in direction, and EIRP ₄ Peak EIRP less than or equal to ₁ . In some embodiments of the present application, EIRP for non-co-sited deployments ₃ EIRP (EIRP) ₄ The acquisition of (a) can be obtained in a manner similar to the CBM capability termination manner:

in general, a terminal can only generate a limited number of beams, and a specific beam to be used for transmitting and receiving is determined by measuring the incoming wave direction. The IBM capable terminal may shape band 1 based on the corresponding beamforming factor of band 1 and obtain a beam ₁ Shaping the frequency band 2 according to the beam shaping factors corresponding to the frequency band 2 to obtain a beam ₂ . Therefore, the beams of the frequency band 1 and the frequency band 2 do not have a one-to-one correspondence. In other words, beam ₁ Corresponding EIRP ₃ Will be different from the unique value under CBM capable terminals but will depend on the corresponding beamforming factor of frequency band 2, i.e. EIRP ₃ Depending on the beam on band 2 employed. Beam ₂ Corresponding EIRP ₄ Similarly. By being in beam ₁ Beam in the peak direction of (a) ₂ The emission power (EIRP) can obtain the corresponding EIRP ₃ I.e. beam ₂ In the beam ₁ Antenna gain value in the peak direction of (a). By the same token, by beam ₂ Beam in the peak direction of (a) ₁ Transmitting power to obtain corresponding EIRP ₄ I.e. beam ₁ In the beam ₂ Antenna gain value in the peak direction of (a). The following is an exemplary illustration in conjunction with table 3.

TABLE 3 Table 3

As shown in table 3, when the network configures the frequency band 1 and the frequency band 2 to transmit beams simultaneously, compared with the scheme of configuring the transmission power of the terminal device in the single frequency band ₁ Sum beam ₂ When the terminal should configure the beam ₁ Sum beam ₂ To ensure peak EIRP ₁ +EIRP ₃ Maximum peak value EIRP less than or equal to the peak value EIRP ₂ +EIRP ₄ And the maximum peak value EIRP is less than or equal to.

Of course, in one implementation, the following manner may be obtained by simplifying the above manner:

by beam matching ₁ Sum beam ₂ The calibration of the peak EIRP of (c) may simplify the corresponding transmit power constraints. The following is an exemplary illustration in conjunction with table 4.

TABLE 4 Table 4

As shown in table 4, when the network configures the transmission power of the band 1 and the band 2 to transmit simultaneously, the terminal should configure the total transmission power of the transmission beam on the band 1 and the transmission beam on the band 2 to ensure peak EIRP compared with the scheme of configuring the transmission power of the terminal device in the single band _m +peak EIRP _n And the maximum peak value EIRP is less than or equal to.

Of course, in another implementation manner, the following manner may be obtained by simplifying the above manner:

by beam matching ₁ Sum beam ₂ The calibration of the peak EIRP of (c) may simplify the corresponding transmit power constraints. An exemplary description is given below in connection with table 5.

TABLE 5

As shown in table 5, when the network configures the transmission power of the band 1 and the band 2 to transmit simultaneously, the terminal should configure the total transmission power of the maximum transmission beam of the transmission beam on the band 1 and the maximum transmission beam of the transmission beam on the band 2 to ensure the peak EIRP, compared with the scheme of configuring the transmission power of the terminal device in the single band _max1 +peak EIRP _max2 And the maximum peak value EIRP is less than or equal to.

In some embodiments, the method 200 may further comprise:

and determining the sum of a plurality of peak EIRP as the total transmitting power of the plurality of frequency bands in the same direction, wherein the plurality of peak EIRP are respectively the peak EIRP of the wave beams on the plurality of frequency bands.

For example, as shown in table 2 or table 4, taking the multiple frequency bands including frequency band 1 and frequency band 2 as an example, the terminal device may configure the total transmit power of the transmit beam on frequency band 1 and the transmit beam on frequency band 2 to ensure peak EIRP _m +peak EIRP _n And the maximum peak value EIRP is less than or equal to.

In some implementations, the method is applied to non-co-sited scenarios. Of course, it is also applicable to co-sited scenarios.

In some implementations, the method applies to independent beam management IBM capable terminals. Of course, it is also applicable to CBM capability terminals.

In some embodiments, the S210 may include:

and configuring the total radiation power TRP of the frequency bands to be smaller than or equal to the maximum TRP.

For example, the terminal device configures the TRP of all beams on the plurality of frequency bands to be less than or equal to the maximum TRP.

In some implementations, the TRP of the plurality of frequency bands is a sum of TRPs of all beams simultaneously transmitted on the plurality of frequency bands.

In some embodiments, the S210 may include:

and configuring each frequency band in the plurality of frequency bands to meet the single-frequency band transmitting power requirement.

In some implementations, the configuring each of the plurality of frequency bands to meet a single band transmit power requirement includes:

for each frequency band, at least one of the following requirements is satisfied:

the maximum transmitting power of the wave beam is smaller than or equal to the maximum peak effective omnidirectional radiation power EIRP;

the maximum transmit power of the beam is greater than or equal to the minimum peak EIRP; or (b)

It should be noted that, in the embodiment of the present application, each frequency band meets the requirement of single-band transmission power, which may be understood that each frequency band as a whole meets the requirement of single-band transmission power, that is, all beams on each frequency band as a whole meets the requirement of single-band transmission power. For example, when a plurality of beams are transmitted in one frequency band, the maximum transmission power of the beams may be: for all beams on the one frequency band (i.e. the plurality of beams), the transmit power in the maximum transmit power direction; similarly, the sum of the radiation power of the beams in all directions may be: the sum of the radiation powers of all beams (i.e. the plurality of beams) in all directions in the one frequency band.
