[0026] For the convenience of understanding, some contents related to the embodiments of the present application are described as follows:

[0027] I. Definition and characteristics of EIRP

[0028] EIRP is defined as the product of the power provided to the antenna in a given direction and the antenna gain relative to an isotropic antenna.

[0029] To specify EIRP accurately, a specific measurement angle needs to be indicated.

[0030] II. Maximum (max) EIRP.

[0031] For terminals, the sum of the average power of all antenna elements is limited to a maximum equivalent isotropically radiated power of +43 dBm.

[0032] III. Terminal power max EIRP limit in NR FR2.

[0033] For the limit of FR2 single carrier uplink power, EIRP is one of the evaluation indicators. For example, for Power Class 3, the terminal is required to transmit a single carrier, and the maximum EIRP in any direction cannot exceed 43 dBm.

[0034] IV. Uplink carrier aggregation (CA) power limit in NR FR2.

[0035] For the case of intra-band carrier aggregation (intra-band CA), when the downlink intra-band contiguous carrier aggregation (intra-band contiguous CA) and the intra-band non-contiguous carrier aggregation (intra-band non-contiguous CA) are aggregated with a single uplink carrier, the maximum transmit power meets the single carrier requirement. The power limit is defined as follows:

[0036] P UMAX ≤ EIRP max ;

[0037] Where P UMAX is the carrier measurement power, defined as:

[0038] P UMAX,f,c represents the carrier measurement power on each carrier f on the serving cell c.

[0039] The signal transmit power control method provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings and some embodiments and application scenarios.

[0040] Please refer to Figure 2 , Figure 2 is a flowchart of a signal transmit power control method provided by the embodiments of the present application, which is executed by a terminal, as shown in Figure 2 , including the following steps:

[0041] In step 201, when N target objects correspond to radio frequency signals that are simultaneously transmitted, the terminal performs transmission power control based on a first equivalent isotropically radiated power.

[0042] N is an integer greater than 1, the target objects include beams, carriers, bands, or antenna panels, and the first equivalent isotropically radiated power is determined based on the equivalent isotropically radiated power of each target object at one spatial angle information.

[0043] In the embodiments of the present application, the above-mentioned carrier can be understood as a component carrier (CC), and the above-mentioned antenna panel can be referred to as a panel.

[0044] Optionally, the simultaneous transmission of radio frequency signals corresponding to the N target objects can be understood as transmitting N radio frequency signals based on N target objects. For example, when the target object is a beam, the simultaneous transmission of radio frequency signals corresponding to the N target objects can be understood as the simultaneous transmission of N radio frequency signals corresponding to N beams, which can also be referred to as transmitting N beams. When the target object is a carrier, the simultaneous transmission of radio frequency signals corresponding to the N target objects can be understood as the simultaneous transmission of N radio frequency signals corresponding to N carriers, which can also be referred to as simultaneously transmitting N carriers. When the target object is a band, the simultaneous transmission of radio frequency signals corresponding to the N target objects can be understood as transmitting N radio frequency signals on N bands simultaneously. When the target object is an antenna panel, the simultaneous transmission of radio frequency signals corresponding to the N target objects can be understood as transmitting N radio frequency signals on N antenna panels simultaneously.

[0045] It should be understood that in the embodiments of the present application, the terminal can first determine whether there are N target objects corresponding to radio frequency signals that are simultaneously transmitted, wherein the simultaneous transmission can be understood as the overlapping of the time domain resources of N radio frequency signals or the same starting time of the time domain resources of N radio frequency signals.

[0046] It should be noted that when the above-mentioned target object is a band or an antenna panel, the radio frequency signal transmitted on each band can be associated with a beam or a carrier, and the radio frequency signal transmitted on each antenna panel can be associated with a beam or a carrier. Therefore, the multi-band or multi-antenna panel scenario can also be understood as a multi-beam or multi-carrier scenario.

[0047] The spatial angle information can be used to represent direction information, and can be understood as spatial angle information corresponding to any direction. In each direction, there is an equivalent isotropic radiation power corresponding to each target object. When performing power limitation, the first equivalent isotropic radiation power is determined based on the equivalent isotropic radiation power of the target object in one spatial angle information, and then the first equivalent isotropic radiation power is used to limit the uplink transmission of the terminal. Therefore, in the multi-beam or multi-carrier scenario, the rationality of the power limitation can be ensured.

[0048] It should be understood that the beam information of the above-mentioned beam can be understood as beam information, spatial relation information, spatial domain transmission filter information, spatial filter information, Transmission Configuration Indicator state (TCI state) information, Quasi co-location (QCL) information or QCL parameters, etc. For example, in some embodiments, when the above-mentioned beam information is understood as spatial domain transmission filter information, the beam involved in the present application can be understood as a spatial domain transmission filter, which can also be called a spatial filter.

[0049] The above-mentioned antenna panel can also be called: antenna group, antenna port group, antenna set, antenna port set, beam set, beam sub-set, antenna array, antenna port array, antenna sub-array, antenna port sub-array, logical entity, entity or antenna entity, etc. The identification of the panel can be called: identification of the antenna panel, identification of the reference signal resource, identification of the reference signal resource set, identification of the TCI state, identification of the QCL information or identification of the spatial relation, etc.

[0050] In the embodiments of the present application, when N target objects corresponding to radio frequency signals are simultaneously transmitted, the terminal performs transmit power control based on the first equivalent isotropic radiation power. N is an integer greater than 1, the target objects include beams, carriers, frequency bands or antenna panels, and the first equivalent isotropic radiation power is determined based on the equivalent isotropic radiation power of each target object in one spatial angle information. In the embodiments of the present application, the definition of the first equivalent isotropic radiation power used for transmit power control in the scenario where multiple beams or multiple carriers work simultaneously is clarified, thereby solving the problem of transmit power control limitation of the terminal in the scenario where multiple beams or multiple carriers work simultaneously.

[0051] Optionally, in some embodiments, the first equivalent isotropic radiation power includes any of the following:

[0052] a sum of the equivalent isotropically radiated power of each of the target objects under a spatial angle information;

[0053] a weighted sum of the equivalent isotropically radiated power of each of the target objects under a spatial angle information.

[0054] In the embodiments of the present application, when the first equivalent isotropically radiated power is a sum of the equivalent isotropically radiated power of each of the target objects under a spatial angle information, it can be understood that the sum value obtained by adding the corresponding equivalent isotropically radiated power of each target object under a spatial angle information represents the first equivalent isotropically radiated power under the spatial angle information.

[0055] When the first equivalent isotropically radiated power is a weighted sum of the equivalent isotropically radiated power of each of the target objects under a spatial angle information, it can be understood that each target object has a weight threshold under a spatial angle information, and the first equivalent isotropically radiated power under the spatial angle information can be obtained by multiplying the corresponding equivalent isotropically radiated power of all target objects under the spatial angle information by the corresponding weight threshold and then performing summation calculation. The weight threshold corresponding to the same target object under different spatial angle information can be the same or different, and can be set according to actual needs, which will not be further limited here.

[0056] In order to better understand the present application, the first equivalent isotropically radiated power will be taken as an example for detailed description below, which is a sum of the equivalent isotropically radiated power of each of the target objects under a spatial angle information.

[0057] In the embodiments of the present application, the first equivalent isotropically radiated power described above can be referred to as a newly defined EIRP, also referred to as an extended EIRP, also referred to as a combined equivalent isotropically radiated power (cEIRP), also referred to as a multi-beam equivalent isotropically radiated power (multi-beam EIRP) or a multi-carrier equivalent isotropically radiated power (multi-CC EIRP), etc. The cEIRP will be taken as an example for description below. At this time, the cEIRP corresponding to the spatial angle information α can be represented as cEIRP(α).

[0058] When the target object described above is a beam, cEIRP(α) = EIRP(beam1, α) + EIRP(beam2, α) + ··· + EIRP(beamN, α). Wherein, EIRP(beamn, α) represents the EIRP value of the nth beam under the spatial angle information α. n n

[0059] As shown in FIG. 1, the spatial angle information α described above can be represented by θ and φ. Figure 3 As shown in FIG. 1, the spatial angle information α described above can be represented by θ and φ.​​ Two angle information are represented, i.e. α can be understood as wherein θ represents a polar angle, also referred to as an inclination angle, a normal angle or a zenith angle, and can be understood as an included angle between a line connecting an origin of a spherical coordinate system to a certain point in space and a positive Z-axis; denotes an azimuth angle, and can be understood as an included angle between a projection line of a line connecting an origin of a spherical coordinate system to a certain point in space on an xy-plane and a positive x-axis. As shown in Figure 4 cEIRP(α1)=EIRP(beam1,α1)+EIRP(beam2,α1)=EIRP

[0060] When the target object is a carrier, cEIRP(α)=EIRP(CC1,α)+EIRP(CC2,α)+······+EIRP(CC n n,α). Wherein EIRP(CC n n,α) represents an EIRP value of an nth CC corresponding to spatial angle information α.

[0061] Optionally, the limit condition of the transmission power can be set according to actual needs, for example, in some embodiments, a maximum value in the first equivalent isotropically radiated power corresponding to each spatial angle information is less than or equal to a preset transmission power limit value.

[0062] In the embodiments of the present application, the maximum value in the first equivalent isotropically radiated power corresponding to each spatial angle information is less than or equal to a preset transmission power limit value, which can be understood as that the first equivalent isotropically radiated power corresponding to any spatial angle information is less than or equal to a preset transmission power limit value. Specifically, when the maximum value in the first equivalent isotropically radiated power corresponding to each spatial angle information is greater than the preset transmission power limit value, the transmission power of part or all of the target objects corresponding to the radio frequency signals can be reduced, for example, the transmission power can be reduced according to the priority order of the target objects, or the transmission power can be reduced according to the size of the transmission power.

[0063] Optionally, the maximum first equivalent isotropically radiated power can be represented as max cEIRP, and the max cEIRP=max(cEIRP(α1),cEIRP(α2),···,cEIRP(α m m). m denotes an mth spatial angle information.

[0064] Optionally, in some embodiments, the preset transmission power limit value includes any of the following:

[0065] A maximum limit equivalent isotropically radiated power agreed by a protocol;

[0066] Preset power value.

[0067] This preset power value can be understood as the power value limited by the U.S. Federal Communications Commission (FCC), or it can be understood as a limitation on transmission power for other reasons. For example, this preset power value can be understood as the power value limited to meet the Maximum Permissible Exposure (MPE) standard. The FCC and some countries have established MPE standards, which include the maximum radiation level or maximum exposure level that can cause harm to the human body after radiation exposure.

[0068] Optionally, in some embodiments, when the target object is a beam, the N beams satisfy at least one of the following:

[0069] Associated with a carrier wave;

[0070] Associated with at least two carriers, each of which is associated with at least one of the beams;

[0071] Associated with a frequency band;

[0072] Associated with at least two frequency bands, each of which is associated with at least one of the beams;

[0073] Associated with an antenna panel;

[0074] It is associated with at least two antenna panels, and each antenna panel is associated with at least one of the said beams.

[0075] Optionally, in some embodiments, when the target object is a carrier, the N carriers satisfy at least one of the following:

[0076] Each of the carriers is associated with at least one beam;

[0077] Associated with an antenna panel;

[0078] The N carriers are associated with at least two panels.

[0079] It should be noted that, since the embodiments of this application clearly define the first equivalent isotropic radiated power used for transmitting power control in scenarios where multiple beams or multiple carriers operate simultaneously, the power transmitted by the terminal can be tested and evaluated based on the first equivalent isotropic radiated power, which is beneficial to improving the rationality of judgments during regulatory requirement testing.

[0080] For example, when performing power test in a certain direction, the probe can be set in a certain direction, and each target object corresponding radio frequency signal is transmitted by the terminal in turn or simultaneously. After detecting each target object corresponding radio frequency signal by the probe, the transmission power of the target object corresponding radio frequency signal can be calculated, so as to determine the equivalent isotropically radiated power of the target object in the direction, and finally determine the first equivalent isotropically radiated power in the direction based on the equivalent isotropically radiated power of all target objects in the direction. Whether the transmission power of the terminal in the direction meets the regulatory requirements is determined based on the first equivalent isotropically radiated power.

[0081] In some embodiments, the terminal can also simultaneously transmit each target object corresponding radio frequency signal first, and all target object corresponding radio frequency signals are detected simultaneously by the probe, so as to obtain the equivalent isotropically radiated power of all target objects in the direction, and finally determine the first equivalent isotropically radiated power in the direction.

[0082] It should be noted that the signal transmission power control method provided by the embodiments of the present application can be executed by a signal transmission power control device, or a control module in the signal transmission power control device for executing the signal transmission power control method. In the embodiments of the present application, the signal transmission power control device executes the signal transmission power control method as an example to illustrate the signal transmission power control device provided by the embodiments of the present application.
