[0036] With reference to the drawings and the embodiments disclosed herein, it should be apparent that the described embodiments are only a small number of the all possible embodiments that can be implemented based on the concepts described herein. Any combination of the described features can be implemented without departing from the scope of the application.

[0037] Figure 1 is a schematic diagram of an application scenario of an embodiment of the present application.

[0038] As shown in Figure 1 , the communication system 100 can include a terminal device 110 and a network device 120. The network device 120 can communicate with the terminal device 110 through the air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0039] It should be understood that the embodiments of the present application are only exemplarily illustrated by the communication system 100, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), 5G communication system (also known as New Radio (NR) communication system), or future communication system, etc.

[0040] In Figure 1 the communication system 100 shown, the network device 120 can be an access network device that communicates with the terminal device 110. The access network device can provide communication coverage for a specific geographic area, and can communicate with terminal devices 110 (such as UEs) located in the coverage area.

[0041] The network device 120 can be an evolved node B (eNB or eNodeB) in a long term evolution (LTE) system, or a next generation radio access network (NG RAN) device, or a base station (gNB) in a NR system, or a radio controller in a cloud radio access network (CRAN), or a relay station, an access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, or a network device in a future evolved public land mobile network (PLMN), etc.

[0042] The terminal device 110 can be any terminal device, including but not limited to a terminal device connected to the network device 120 or other terminal devices by wire or wireless connection.

The access terminal can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device, or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a 5G network, or a terminal device in a future evolved network, etc.

[0044] The terminal device 110 can be used for device to device (D2D) communication.

[0045] The wireless communication system 100 can further include a core network device 130 in communication with the base station, which can be a 5G core network (5GC) device, e.g., an Access and Mobility Management Function (AMF), e.g., an Authentication Server Function (AUSF), e.g., a User Plane Function (UPF), e.g., a Session Management Function (SMF). Alternatively, the core network device 130 can also be an Evolved Packet Core (EPC) device of an LTE network, e.g., a Session Management Function + Core Packet Gateway (SMF + PGW-C) device. It should be understood that the SMF + PGW-C can implement the functions of both the SMF and the PGW-C. In the process of network evolution, the above-mentioned core network device can also be called by other names, or new network entities can be formed by dividing the functions of the core network, which is not limited by the embodiments of the present application.

[0046] The various functional units in the communication system 100 can also be connected and communicate through a next generation (NG) interface.

[0047] For example, the terminal device establishes an air interface connection with the access network device through the NR interface, which is used to transmit user plane data and control plane signaling; the terminal device can establish a control plane signaling connection with the AMF through the NG interface 1 (N1 for short); the access network device, e.g., a next generation wireless access base station (gNB), can establish a user plane data connection with the UPF through the NG interface 3 (N3 for short); the access network device can establish a control plane signaling connection with the AMF through the NG interface 2 (N2 for short); the UPF can establish a control plane signaling connection with the SMF through the NG interface 4 (N4 for short); the UPF can interact with the data network to transmit user plane data through the NG interface 6 (N6 for short); the AMF can establish a control plane signaling connection with the SMF through the NG interface 11 (N11 for short); the SMF can establish a control plane signaling connection with the PCF through the NG interface 7 (N7 for short).

[0048] Figure 1Exemplarily, one base station, one core network device and two terminal devices are shown, optionally, the wireless communication system 100 can include a plurality of base station devices and each base station can include other numbers of terminal devices within the coverage range, and the embodiments of the present application do not limit this.

[0049] It should be understood that the devices with communication functions in the network / system in the embodiments of the present application can be referred to as communication devices. Figure 1 Taking the communication system 100 shown as an example, the communication devices can include network devices 120 and terminal devices 110 with communication functions, and the network devices 120 and the terminal devices 110 can be the devices described above, which will not be described herein again; the communication devices can also include other devices in the communication system 100, such as network controllers, mobile management entities and other network entities, and the embodiments of the present application do not limit this.

[0050] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" herein is only used to describe the association relationship of the associated objects. For example, A and / or B can represent three cases: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " generally represents an "or" relationship between the associated objects.

[0051] In the 5G NR system, a millimeter wave operating frequency band is introduced, and the millimeter wave operating frequency is usually above 10 GHz.

[0052] In order to facilitate understanding of the scheme of the present application, the related content of the millimeter wave spectrum is described below.

[0053] Figure 2 is an example of the 5G millimeter wave frequency band provided by the embodiments of the present application.

[0054] As shown in Figure 2 n257, n258, n259, n260 and n261 are all millimeter wave frequency band numbers. Among them, the frequency spectrum range of n257 is 26.5GHz-29.5GHz, the frequency spectrum range of n258 is 24.25GHz-27.5GHz, the frequency spectrum range of n259 is 39.5GHz-43.5GHz, the frequency spectrum range of n260 is 37GHz-40GHz, and the frequency spectrum range of n261 is 27.5GHz-28.35GHz.

[0055] Due to the very large spatial propagation loss of electromagnetic waves in the millimeter wave frequency band, the coverage range of the electromagnetic wave signal is limited. In order to overcome the large spatial loss, the terminal generally uses an antenna array composed of multiple antenna elements to form narrow beam transmission and reception of signals in the millimeter wave frequency band, and these narrow beams have relatively strong directivity. Figure 3is an example of a 5G millimeter wave terminal based on a beam communication mode provided by the embodiments of the present application. As shown in Figure 3 The base station and the terminal communicate through narrow beams with strong directivity.

[0056] When the terminal works in multiple frequency bands (such as frequency band (Band) A and frequency band (Band) B) at the same time, the terminal needs to perform beamforming on multiple frequency bands at the same time to communicate with the base station. From the terminal implementation, there are two cases:

[0057] One case is that the terminal has only one set of transmitting / receiving antenna units, at this time, only one set of beamforming factors can be used to perform beamforming on the frequency bands at the same time, that is, only the beamforming factor corresponding to one frequency band can be used to perform beamforming on the frequency band, and the other frequency band is performed beamforming according to the same beamforming factor. In this case, the terminal can be called a terminal with common beam management (CBM) capability or a CBM capable terminal. Figure 4 is an example of a CBM capable terminal provided by the embodiments of the present application. As shown in Figure 4 The CBM capable terminal has only one set of transmitting / receiving antenna units, that is, there is a phase shifter and an antenna array corresponding to the set of transmitting / receiving antenna units, and frequency band A and frequency band B can be beamformed through the set of transmitting / receiving antenna units and communicate with the base station, but only one frequency band corresponding to the beamforming parameter can be used to perform beamforming on frequency band A and frequency band B at the same time.

[0058] The other case is that the terminal has two sets (or multiple sets) of transmitting / receiving antenna units, and at the same time, the beamforming factors corresponding to the two frequency bands can be used to perform beamforming on the two frequency bands respectively, and two (or multiple) independent beams are generated. In this case, the terminal can be called a terminal with independent beam management capability (IBM) or an IBM capable terminal. Figure 5 is an example of an IBM capable terminal provided by the embodiments of the present application. As shown in Figure 5 The IBM capable terminal has two sets of transmitting / receiving antenna units, that is, each set of transmitting / receiving antenna units has its own phase shifter and antenna array; frequency band A and frequency band B perform beamforming through their own set of transmitting / receiving antenna units and communicate with the base station; at the same time, the beamforming factor of frequency band A can be used to perform beamforming on frequency band A and the beamforming factor of frequency band B can be used to perform beamforming on frequency band B, and finally two (or multiple) independent beams are generated.

[0059] For the CBM-capable terminal, since different frequency bands share the same set of transmit / receive antenna elements, only one frequency band can be beamformed at the same time, which means that only one frequency band can be accurately pointed in one direction at the same time. Therefore, in most cases, the CBM-capable terminal working in frequency band A and frequency band B at the same time can only be in a co-sited scenario, which can also be referred to as a multi-frequency co-beam scenario. Figure 6 is an example of a co-sited scenario provided by the embodiments of the present application. As shown in Figure 6 , at the same time, frequency band A and frequency band B communicate with base station 1 and base station 2 through a common beam.

[0060] For the IBM-capable terminal, since two or more independent beams can be generated at the same time, which means that the terminal can point the beams in different directions at the same time, the IBM-capable terminal working in frequency band A and frequency band B at the same time can be in a non-co-sited scenario, which can also be referred to as a multi-frequency independent beam scenario. Figure 7 is an example of a non-co-sited scenario provided by the embodiments of the present application. As shown in Figure 7 , at the same time, frequency band A and frequency band B communicate with base station 1 and base station 2 through independent beams.

[0061] Generally, the IBM-capable terminal has higher flexibility and can work in different base station deployment scenarios, while the CBM-capable terminal has limited application scenarios in the network. However, from the perspective of terminal implementation, the IBM-capable terminal needs to have multiple transmit / receive antenna elements, and its implementation complexity, cost and power consumption are higher than those of the CBM-capable terminal. Therefore, in the actual network, the terminal generally comprehensively considers complexity, cost, power consumption and flexibility, and selects different implementation methods.

[0062] To facilitate understanding of the scheme of the present application, the scheme of configuring transmit power of a terminal device under a single frequency band is described below.

[0063] For single frequency band, the maximum transmit power of terminal device is limited by parameters such as maximum peak effective isotropic radiated power (max peak EIRP), maximum total radiated power (max TRP), minimum peak transmit power (min peak EIRP) and spherical coverage. The effective isotropic radiated power (EIRP) is also called equivalent isotropic radiated power (EIRP). For example, the EIRP of a transmitting device can be the power radiated by the receiving end and the transmitting end antenna in the beam center axial direction, that is, the product of the power supplied by the radio transmitter to the antenna and the absolute gain of the antenna in a given direction can be taken as an index representing the transmitting capability of the transmitting end. The total radiated power (TRP) can be obtained by integrating and averaging the transmit power of the entire radiation sphere, which is used to reflect the transmit power of the whole machine, and is related to the transmit power of the device in the conduction case and the antenna radiation performance.

[0064] Figure 8 is an example of the single frequency band transmit power configuration requirement provided by the embodiments of the present application.

[0065] As shown in Figure 8 , the terminal can generate multiple beams (usually only one beam works at the same time) in a certain frequency band, and the requirements for the maximum transmit power of the terminal are as follows:

[0066] 1. In order to avoid interference to other terminals in the communication direction, the maximum power allowed to be transmitted by the terminal in the maximum transmit power direction (assuming Beam 1) cannot exceed max peak EIRP, that is, peak EIRP1≤maxPeak EIRP. Since the peak EIRP of Beam 1 is greater than the peak EIRP of other Beams, it also means that other Beams will also meet the requirement of max peak EIRP. Optionally, the max peak EIRP can come from the regulatory requirements of government regulatory agencies.

[0067] 2. To avoid interference to other direction terminals, the sum of the radiation power of the terminal radiation beams in all directions cannot exceed max TRP. Assuming that the beam with the maximum radiation power in all directions is beam 2, the sum of the radiation power of beam 2 in each direction TRP2≤ max TRP. Since the total radiation power TRP of beam 2 is greater than that of other beams, it also means that other beams will also meet the requirement of max TRP. Optionally, the index max TRP can come from the regulatory requirements of the government regulatory agency.

[0068] 3. To ensure the uplink coverage capability of the terminal, the maximum power transmitted by the terminal in the maximum transmission power direction (assuming it is Beam1) should at least meet the requirement of min peak EIRP.

[0069] 4. To ensure the mobility and uplink coverage of the terminal, the statistical curve of the peak transmission power in all directions should be able to meet the requirement of spherical coverage, that is, the peak EIRP corresponding to a certain percentage on the cumulative distribution function (CDF) curve should be higher than the threshold value. Figure 9 is an example of the spherical coverage requirement provided by the embodiments of the present application. As shown in Figure 9 , the peak EIRP corresponding to 50% on the CDF curve (i.e. 11.5) should be higher than the threshold value.

[0070] As described above, with the improvement of the capability of the terminal, CBM-capable terminals and IBM-capable terminals are likely to generate multiple beams on multiple frequency bands at the same time, and currently there is only a scheme for configuring the transmission power of terminal devices under a single frequency band. However, since multiple beams will generate gain with each other, if the scheme for configuring the transmission power of terminal devices under a single frequency band is continued to be used to configure the transmission power of terminal devices under multiple frequency bands, it is likely to cause the configuration accuracy of the transmission power to not meet the requirements. For example, when the network configures the terminal device to work on multiple frequency bands at the same time, how to configure the transmission power of the terminal to meet the requirements of multiple frequency band coverage and reduce interference at the same time still needs to be studied, that is, the power configuration scheme of the terminal device needs to be further improved in the field. The present application configures the maximum transmission power of the terminal device by analyzing the power interaction principle under the multiple frequency band simultaneous working scenario of the terminal, that is, provides a method and a terminal device for configuring the transmission power, improves the multiple frequency band power configuration scheme of the terminal device, and can ensure that the transmission power of the millimeter wave terminal under the multiple frequency band parallel transmission meets the regulatory requirements and ensures the uplink coverage.

[0071] As described above, in the millimeter wave frequency band in the NR system, the terminal usually adopts beamforming to concentrate the transmit power, overcome the large propagation loss, and improve the uplink and downlink coverage capability. At the same time, it is necessary to ensure that the transmit power of the terminal is not too large to avoid interference to the terminal in other directions. Therefore, the maximum peak EIRP, maximum TRP, minimum peak EIRP, and spherical coverage and other transmit power indicators are introduced to constrain the power.

[0072] In this application, when the terminal is configured to transmit in multiple frequency bands at the same time, such as carrier aggregation (CA) or dual connection (DC), the transmit power of the terminal will increase, and it is necessary to consider how to ensure that the terminal meets the regulatory requirements of the maximum peak EIRP, the maximum TRP, the minimum peak EIRP, and the spherical coverage. In some embodiments, the maximum peak EIRP, the maximum TRP, or the minimum peak EIRP can be required separately for each frequency band, that is, the terminal only needs to configure the power on each frequency band according to the single frequency band requirement. In some embodiments, the maximum peak EIRP and / or the minimum peak EIRP can be required for the terminal as a whole, that is, the terminal needs to consider the power of all simultaneously transmitting 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 can be required for the terminal as a whole, that is, the terminal needs to ensure that the total radiation power of the simultaneously transmitting frequency bands does not exceed the maximum TRP.

[0073] Figure 10 FIG. 2 is a schematic flowchart of a method 200 for configuring transmit power provided by an embodiment of the present application. The method 200 can be performed by a terminal device, for example, can be a terminal device as shown in FIG. 1, and can also be a millimeter wave terminal. Figure 1

[0074] As shown in FIG. 2, the method 200 can include the following parts or all of them: Figure 10

[0075] S210, in the case of transmitting in multiple frequency bands in parallel, configuring the transmit power of the multiple frequency bands to meet the transmit power requirement.

[0076] ​​For example, the terminal device can be configured with the transmission power of the multiple frequency bands 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 regulatory requirements of maximum peak EIRP, maximum TRP, minimum peak EIRP, and spherical coverage through analysis of the scenario of parallel transmission of the multiple frequency bands. For example, through analysis of the scenario of parallel transmission of the multiple frequency bands, the terminal device can ensure that the power of all simultaneously transmitted frequency bands in the same direction meets the maximum peak EIRP and / or minimum peak EIRP. Based on this, the terminal device meets the uplink coverage requirement while avoiding interference with other users.

[0077] The scheme provided in the present application perfects the multi-frequency band power configuration scheme of the terminal device. In the case of parallel transmission of multiple frequency bands, the transmission power of the multiple frequency bands is configured to meet the transmission power requirement, which can ensure that the millimeter wave terminal meets the regulatory requirements in the case of parallel transmission of multiple frequency bands, while ensuring uplink coverage.

[0078] In some embodiments, the S210 can include:

[0079] The total transmission power of the multiple frequency bands in the same direction is less than or equal to the maximum peak effective isotropic radiated power EIRP, and / or the total transmission power of the multiple frequency bands in the same direction is greater than or equal to the minimum peak EIRP.

[0080] In other words, the maximum peak EIRP can be configured according to the overall requirement of the terminal, i.e., the peak EIRP of the terminal device which is greatly related to directivity.

[0081] In some embodiments, the method 200 can further include:

[0082] The sum of the first peak EIRP and at least one first EIRP is determined as the total transmission power of the multiple frequency bands in the same direction;

[0083] The first peak EIRP is the peak EIRP of a first beam on a first frequency band of the multiple frequency bands, the first beam is a beam formed by beamforming through a beamforming factor of the first frequency band, and the at least one first EIRP includes the transmission power of beams other than the first beam on the multiple frequency bands in the direction of the first peak EIRP.

[0084] In some implementations, the method 200 can further include:

[0085] The at least one first EIRP is determined.

[0086] In some implementations, at least one first beam corresponding to the first frequency band is determined; the transmit power of the at least one first beam in the direction of the first peak EIRP is determined as the at least one first EIRP. Optionally, the at least one first beam includes beams formed by beamforming at least one frequency band other than the first frequency band using the beamforming factor of the first frequency band. Optionally, the method is applied to co-located scenarios or non-co-located scenarios. Optionally, the method is applied to terminals with common beam management (CBM) capabilities.

[0087] The following describes, with reference to specific embodiments, a scheme for configuring transmit power using the maximum peak rate EIRP for CBM-capable terminals in both co-site and non-co-site deployments.

[0088] Example 1:

[0089] Figure 11 These are examples of the transmit power of the CBM-capable terminal provided in this application under different network scenarios. For example... Figure 11 As shown, for CBM-capable terminals, since the two frequency bands use the same beamforming factor, assuming that the beamforming factor is based on frequency band 1, the beam 1 of frequency band 1 can accurately point to the target base station 1, while the beam of frequency band 2 has a pointing deviation from the target base station direction. Figure 12 These are examples of the maximum transmit power of CBM-capable terminals under different deployment scenarios provided in the embodiments of this application. For example... Figure 12 As shown, regardless of whether the deployment is co-located or separate, the maximum transmit power (EIRP) of the terminal when operating concurrently on two frequency bands is either peak EIRP1+EIRP3 or peak EIRP2+EIRP4. Therefore, to meet the maximum peak EIRP target, peak EIRP1+EIRP3 and peak EIRP2+EIRP4 need to be considered or determined. In other words, the problem in implementing this solution lies in how to obtain EIRP3 and EIRP4.

[0090] Wherein, EIRP3 is the power intensity of beam 2 in the direction of peak EIRP1, and EIRP3 ≤ peak EIRP2. Similarly, EIRP4 is the power intensity of beam 1 in the direction of peak EIRP2, and EIRP4 ≤ peak EIRP1. In some embodiments of this application, EIRP3 and EIRP4 can be obtained by one of the following methods:

[0091] Generally, the terminal can only generate a limited number of beams, and through the measurement of the direction of the incoming wave, it is determined which beam is used for transceiving, thereby it can be determined whether the peak EIRP1 or the peak EIRP2 needs to be considered. Assuming that the peak EIRP1 needs to be considered, i.e. the beamforming factor of the CBM-capable terminal is the beamforming factor corresponding to frequency band 1, i.e. beam 1 is obtained through the beamforming factor corresponding to frequency band 1, and at the same time, the beamforming factor is applied to frequency band 2 to obtain the corresponding beam 2, it can be found that the beams of frequency band 1 and frequency band 2 have a one-to-one correspondence. Through the beam 2 transmit power (EIRP) in the peak direction of beam 1, the corresponding EIRP3 can be obtained, i.e. the antenna gain value of beam 2 in the peak direction of beam 1. Similarly, through the beam 1 transmit power in the peak direction of beam 2, the corresponding EIRP4 can be obtained, i.e. the antenna gain value of beam 1 in the peak direction of beam 2. The following is an exemplary description in combination with Table 1.

[0092] Table 1

[0093]

[0094] As shown in Table 1, compared with the scheme of configuring the transmit power of the terminal device under a single frequency band, when the network configures the terminal to transmit simultaneously in frequency band 1 and frequency band 2, the terminal should configure the transmit power of beam 1 and beam 2 to ensure that peak EIRP1+EIRP3≤maximum peak EIRP, and peak EIRP2+EIRP4≤maximum peak EIRP.

[0095] Of course, the above-mentioned manner can be simplified to obtain the following manner:

[0096] Through the calibration of the peak EIRP of beam 1 and beam 2, the corresponding transmit power constraint condition can be simplified. The following is an exemplary description in combination with Table 2.

[0097] Table 2

[0098]

[0099] As shown in Table 2, compared with the scheme of configuring the transmit power of the terminal device under a single frequency band, when the network configures frequency band 1 and frequency band 2 to transmit simultaneously, the terminal should configure the total transmit power of the transmit beam on frequency band 1 and the transmit beam on frequency band 2 to ensure that peak EIRP1+peak EIRP2≤maximum peak EIRP.

[0100] In some embodiments, the method further comprises: determining at least one second beam adopted by at least one frequency band of the plurality of frequency bands except the first frequency band; determining the transmission power of the at least one second beam in the first peak EIRP direction as the at least one first EIRP. Optionally, the at least one second beam comprises beams formed by beamforming the at least one frequency band with at least one beamforming factor respectively, and the at least one beamforming factor corresponds to the at least one frequency band one by one. Optionally, the method is applied to a non-co-sited scenario. Optionally, the method is applied to an IBM-capable terminal.

[0101] The following will be described in combination with specific embodiments, taking the scheme of configuring transmission power by using maximum peak rate EIRP of an IBM-capable terminal in co-sited deployment and non-co-sited deployment as an example.

[0102] Embodiment 2:

[0103] Figure 13 is an example of transmission power of an IBM-capable terminal in different network scenarios provided by the embodiments of the present application. As shown in Figure 13 , for the IBM-capable terminal, since two frequency bands can adopt independent beamforming factors, and the beamforming factors are obtained based on the corresponding base station, both beams can accurately point to the target base station. Figure 14 is an example of maximum transmission power of an IBM-capable terminal in different deployment scenarios provided by the embodiments of the present application. As shown in Figure 14 , since the IBM-capable terminal in the co-sited deployment case and the IBM-capable terminal in the non-co-sited deployment case have beams with different pointing directions, different configuration requirements need to be determined based on different scenarios. Specifically, in the co-sited deployment case, the maximum transmission power (EIRP) of the IBM-capable terminal when two frequency bands are concurrent is peak EIRP1+ peak EIRP2, and accordingly peak EIRP1+ peak EIRP2≤ maximum peak EIRP needs to be met; in the non-co-sited deployment case, the maximum transmission power (EIRP) of the two frequency bands when concurrent is peak EIRP1+ EIRP3 or peak EIRP2+ EIRP4, and at this time peak EIRP1+ EIRP3≤ maximum peak EIRP and peak EIRP2+ EIRP4≤ maximum peak EIRP need to be met.

[0104] , wherein EIRP3 is the power intensity of beam 2 in the direction of peak EIRP1, and EIRP3≤ peak EIRP2. Similarly, EIRP4 is the power intensity of beam 1 in the direction of peak EIRP2, and EIRP4≤ peak EIRP1. In some embodiments of the present application, EIRP3 and EIRP4 for non-co-sited deployment can be obtained in a manner similar to that in the CBM-capable terminal manner:

[0105] Generally, the terminal can only generate a limited number of beams, and determine which beam to use for transmission and reception through the measurement of the direction of the incoming wave. The IBM capable terminal can perform beamforming on frequency band 1 based on the beamforming factor corresponding to frequency band 1 to obtain beam 1, and perform beamforming on frequency band 2 based on the beamforming factor corresponding to frequency band 2 to obtain beam 2. Therefore, the beams of frequency band 1 and frequency band 2 do not have a one-to-one correspondence. In other words, the EIRP3 corresponding to beam 1 will not be a unique value under the CBM capable terminal, but will depend on the beamforming factor corresponding to frequency band 2, that is, EIRP3 is related to the beam on frequency band 2 used. Similarly, the EIRP4 corresponding to beam 2 is also similar. The corresponding EIRP3 can be obtained by the beam 2 transmit power (EIRP) in the peak direction of beam 1, that is, the antenna gain value of beam 2 in the peak direction of beam 1. Similarly, the corresponding EIRP4 can be obtained by the beam 1 transmit power in the peak direction of beam 2, that is, the antenna gain value of beam 1 in the peak direction of beam 2. The following is an exemplary description in conjunction with Table 3.

[0106] Table 3

[0107]

[0108] As shown in Table 3, compared with the scheme of configuring the transmit power of the terminal device under a single frequency band, when the network configures frequency band 1 and frequency band 2 to simultaneously transmit beam 1 and beam 2, the terminal should configure the transmit power of beam 1 and beam 2 to ensure that peak EIRP1+EIRP3≤maximum peak EIRP, and peak EIRP2+EIRP4≤maximum peak EIRP.

[0109] Of course, in an implementation mode, the above-mentioned mode can be simplified to obtain the following mode:

[0110] The corresponding transmit power constraint condition can be simplified by calibrating the peak EIRP of beam 1 and beam 2. The following is an exemplary description in conjunction with Table 4.

[0111] Table 4

[0112]

[0113] As shown in Table 4, compared with the scheme of configuring the transmit power of the terminal device under a single frequency band, when the network configures frequency band 1 and frequency band 2 to simultaneously transmit, the terminal should configure the total transmit power of the transmit beam on frequency band 1 and the transmit beam on frequency band 2 to ensure that peak EIRP m + peak EIRP n ≤ maximum peak EIRP.

[0114] Of course, in another implementation mode, the above-mentioned mode can be simplified to obtain the following mode:

[0115] The corresponding transmit power constraint condition can be simplified by the calibration of the peak EIRP of the beam 1 and the beam 2. The following is an exemplary description in combination with Table 5.

[0116] Table 5

[0117]

[0118] As shown in Table 5, compared with the scheme of configuring the transmit power of the terminal device in a single frequency band, when the network configures the frequency band 1 and the frequency band 2 to transmit simultaneously, the terminal should configure the total transmit power of the maximum transmit beam of the transmit beam on the frequency band 1 and the transmit beam on the frequency band 2 to ensure that the peak EIRP max1 + peak EIRP max2 ≤ maximum peak EIRP.

[0119] In some embodiments, the method 200 can further include:

[0120] determining the sum of the plurality of peak EIRPs as the total transmit power of the plurality of frequency bands in the same direction, the plurality of peak EIRPs being the peak EIRP of the beam on the plurality of frequency bands, respectively.

[0121] For example, as shown in Table 2 or Table 4, taking the case that the plurality of frequency bands include the frequency band 1 and the frequency band 2, the terminal device can configure the total transmit power of the transmit beam on the frequency band 1 and the transmit beam on the frequency band 2 to ensure that the peak EIRP m + peak EIRP n ≤ maximum peak EIRP.

[0122] In some implementations, the method is applied to a non-co-site scenario. Of course, it can also be applied to a co-site scenario.

[0123] In some implementations, the method is applied to an independent beam management (IBM) capable terminal. Of course, it can also be applied to a CBM capable terminal.

[0124] In some embodiments, the S210 can include:

[0125] configuring the total radiated power (TRP) of the plurality of frequency bands to be less than or equal to a maximum TRP.

[0126] 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.

[0127] In some implementations, the TRP of the plurality of frequency bands is the sum of the TRP of all beams transmitting simultaneously on the plurality of frequency bands.

[0128] In some embodiments, the S210 can include:

[0129] each of the plurality of frequency bands is configured to satisfy a single frequency band transmit power requirement.

[0130] In some implementations, the configuring each of the plurality of frequency bands to satisfy a single frequency band transmit power requirement includes:

[0131] for the each frequency band, at least one of the following requirements is satisfied:

[0132] a maximum transmit power of a beam is less than or equal to a maximum peak effective isotropic radiated power (EIRP);

[0133] a sum of radiated power of a beam in all directions is less than or equal to a maximum total radiated power (TRP);

[0134] a maximum transmit power of a beam is greater than or equal to a minimum peak EIRP; or

[0135] a statistical curve of peak EIRP in all directions satisfies a surface coverage requirement.

[0136] It should be noted that, in the embodiments of the present application, the single frequency band transmit power requirement satisfied by each frequency band can be understood as that each frequency band as a whole satisfies the single frequency band transmit power requirement, i.e., all beams on each frequency band as a whole satisfy the single frequency band transmit power requirement. For example, when a frequency band transmits multiple beams, the maximum transmit power of the beams can be: the transmit power in the direction of the maximum transmit power for all beams (i.e., the multiple beams) on the frequency band; similarly, the sum of radiated power of the beams in all directions can be: the sum of radiated power of all beams (i.e., the multiple beams) on the frequency band in all directions.
