The ue 11 may establish communication with the network-side device 12, where the network in the drawing may indicate that the ue 11 wirelessly establishes communication with the network-side device 12, and the network-side device 12 may be a Transmission Reception Point (TRP), or may be a base station, and the base station may be a macro station, such as an LTE eNB, a 5G NR NB, or the like; the network side device 12 may also be an Access Point (AP).

It should be noted that, in the embodiment of the present invention, the specific type of the network-side device 12 is not limited, and the specific functions of the user terminal 11 and the network-side device 12 will be described in detail through a plurality of embodiments below.

Referring to fig. 2, fig. 2 is a flowchart of a method for calculating transmit power according to an embodiment of the present invention, where the method is applied to a user terminal, and as shown in fig. 2, the method includes the following steps:

step 201, obtaining a path loss compensation value between a downlink frequency point and an uplink frequency point.

The downlink frequency point may be a frequency point for uplink transmission of the user terminal, and the downlink frequency point may be a frequency point for downlink transmission of the user terminal. And the downlink frequency point and the uplink frequency point may be frequency points in the frequency spectrum of the same system, or frequency points in the frequency spectrum of different systems, for example: an LTE system and a 5G New Radio (NR) system coexist, and an LTE spectrum of 1.8GHz (or 900MHz) is used, and uplink frequencies of the 5G NR system include 1.8GHz (or 900MHz) and 3.5GHz, and downlink frequencies include 3.5GHz, for example, as shown in fig. 3, where a user terminal in a white area may use 3.5GHz for downlink transmission, and may use 1.8GHz and/or 3.5GHz for uplink transmission, and a user terminal in a gray area may use 3.5GHz for downlink transmission, and may only use 1.8GHz for uplink transmission. And the path loss difference between 3.5GHz and 1.8GHz is larger due to the large frequency point difference, so that the step 201 can obtain the path loss compensation value between the downlink frequency point 3.5GHz and the uplink frequency point 1.8 GHz.

Preferably, the path loss compensation value (PLoffset) may indicate a difference value between a path loss (PL _ DL) of the downlink frequency bin and a path loss PL _ UL of the uplink frequency bin. And the difference may be a difference between the path loss of the downlink frequency bin and the path loss of the uplink frequency bin, that is, the PLoffset is PL _ DL-PL _ UL. The path loss compensation value indicates the difference value between the path loss of the downlink frequency point and the path loss of the uplink frequency point, so that the accuracy of the transmitting power can be improved. Of course, the path loss compensation value may also be a path loss value indicating that the uplink frequency point needs to be compensated with respect to the downlink frequency point.

In addition, the above-mentioned obtaining of the path loss compensation value may be sent by a receiving network side device, or set by a user terminal, and so on.

And 202, calculating the transmitting power of the uplink signal based on the path loss compensation value.

After obtaining the path loss compensation value, step 202 may calculate the transmission power of the uplink signal, for example: the transmission power is calculated according to a calculation formula obtained in advance, or the path loss compensation value may be calculated according to a mapping relationship between a path loss compensation value obtained in advance and the transmission power, and the like.

And the uplink signal may include: a Physical Random Access Channel (PRACH) Preamble (Preamble), a Physical Uplink Shared Channel (PUSCH) Signal, a Channel Sounding Reference Signal (SRS), or a Physical Uplink Control Channel (PUCCH) Signal. Namely, the transmission power of the PRACH Preamble, the PUSCH signal, the SRS, or the PUCCH signal may be calculated by the above method.

In this embodiment, the transmission power of the uplink signal is calculated based on the path loss compensation value between the downlink frequency point and the uplink frequency point, so that the accuracy of the transmission power can be improved.

Referring to fig. 4, fig. 4 is a flowchart of another method for calculating transmit power according to an embodiment of the present invention, where the method is applied to a user terminal, and as shown in fig. 4, the method includes the following steps:

step 401, obtaining a path loss compensation value between a downlink frequency point and an uplink frequency point.

Optionally, obtaining the path loss compensation value between the downlink frequency point and the uplink frequency point includes:

and receiving a path loss compensation value between the downlink frequency point and the uplink frequency point sent by the network side equipment.

In this embodiment, the path loss compensation value may be sent to the ue by the network device, so as to reduce power consumption of the ue. Preferably, the path loss compensation value may be transmitted by the network side device through another SIB such as a System Information Block (SIB) 1, an SIB2, or remaining System Information (remaining SI) when the ue initially accesses the network side device, or may be transmitted through higher layer signaling in the embodiment of the present invention.

In addition, in this embodiment, the path loss compensation value may be determined by the downlink frequency point and the uplink frequency point, that is, the network side device determines the path loss compensation value according to the downlink frequency point and the uplink frequency point. Such as: the path loss compensation values at 3.5GHz downlink and 1.8GHz uplink are different from the path loss compensation values at 3.5GHz downlink and 900MHz uplink.

Optionally, the path loss compensation value includes:

and a first preset value corresponding to the downlink frequency point and the uplink frequency point, wherein the first preset value is configured for at least two user terminals by the network side equipment.

The first preset value corresponding to the downlink frequency point and the uplink frequency point may be understood as that the first preset value is determined by the downlink frequency point and the uplink frequency point, and the path loss compensation values corresponding to different downlink frequency points and different uplink frequency points may be different. In addition, the at least two user terminals may be some or all terminals connected to the first network-side device, specifically, the path loss compensation values of the same network-side device may be configured, and different network-side devices may configure different path loss compensation values, for example: different base stations can configure different path loss compensation values, for example, different scenes configure different path loss compensation values.

Optionally, the path loss compensation value includes:

and a second preset value corresponding to the downlink frequency point and the uplink frequency point, wherein the second preset value is configured for the user terminal by the network side equipment.

The configuration of the network side device for the user terminal may be to configure a dedicated path loss compensation value for the user terminal according to a location of the user terminal, a service type, or a terminal capability, so as to further improve accuracy of the transmission power. And different network side devices can also configure different path loss compensation values for the same user terminal so as to improve the precision of the path loss compensation values.

Optionally, the path loss compensation value includes:

and a third preset value corresponding to the downlink frequency point and the uplink frequency point, wherein the third preset value corresponds to at least two network side devices or a preset network area.

The preset network area may be a network in a certain area, or a network in a certain specific environment, or may be a whole network, that is, the whole network uses the same fixed path loss compensation value.

Preferably, the third preset value is an average value of the path loss compensation values between the downlink frequency point and the uplink frequency point in at least two communication scenarios. The at least two communication scenarios may include communication scenarios of cells with different geographic features or different radii. In this embodiment, the third preset value is an average value of the path loss compensation values between the downlink frequency point and the uplink frequency point in at least two communication scenarios, so that the reliability of the path loss compensation value can be ensured.

Preferably, the third preset value is an average value of the path loss compensation values between the downlink frequency point and the uplink frequency point under at least two line-of-sight conditions. The at least two Line-of-Sight transmission conditions may include Line-of-Sight transmission (LOS) and non-Line-of-Sight transmission (NLOS). In this embodiment, the third preset value is an average value of the path loss compensation values between the downlink frequency point and the uplink frequency point under at least two line-of-sight conditions, so that the reliability of the path loss compensation value can be ensured.

Preferably, the third preset value is an average value of a set of path loss compensation values, where the set of path loss compensation values includes path loss compensation values between the downlink frequency point and the uplink frequency point in at least two communication scenes, and includes path loss compensation values between the downlink frequency point and the uplink frequency point under at least two line-of-sight conditions. In this embodiment, the reliability of the path loss compensation value can be further ensured.

Optionally, the obtaining of the path loss compensation value between the downlink frequency point and the uplink frequency point includes:

and setting a path loss compensation value between the downlink frequency point and the uplink frequency point.

In this embodiment, the user terminal may determine the path loss compensation value according to the downlink frequency point and the uplink frequency point. Such as: the path loss compensation values at 3.5GHz downlink and 1.8GHz uplink are different from the path loss compensation values at 3.5GHz downlink and 900MHz uplink. The user terminal sets the path loss compensation value, so that the transmission overhead can be reduced, and the network resources can be saved. Preferably, the setting of the path loss compensation value between the downlink frequency point and the uplink frequency point includes:

taking a fourth preset value corresponding to the downlink frequency point and the uplink frequency point as the path loss compensation value; or

And setting a path loss compensation value between the downlink frequency point and the uplink frequency point according to pre-acquired factor information related to the path loss, wherein different factor information corresponds to different path loss compensation values.

The fourth preset value may be a fixed value, such as N dB, where N is a real number, that is, after the downlink frequency point and the uplink frequency point are determined, the path loss compensation value is also determined.

In addition, the factor information includes, but is not limited to, the transmission power of the network side device or the recorded path loss size, and the like, and the accuracy of the path loss compensation value can be improved because the path loss compensation value is set according to the factor information.

Optionally, before obtaining the path loss compensation value between the downlink frequency point and the uplink frequency point, the method further includes:

receiving set information of an uplink frequency point set available for the user terminal, which is sent by network side equipment;

and selecting the uplink frequency point for uplink transmission in the uplink frequency point set according to the path loss of the downlink frequency point.

The uplink frequency point set may include a plurality of available uplink frequency points of the user terminal, for example: as shown in fig. 3, when the user terminal is located at the overlapping position of the two regions, the available uplink frequency points include 3.5GHz and 1.8GHz, so that the user terminal can select the corresponding uplink frequency point according to the path loss of the downlink frequency point. The path loss of the downlink frequency point may be measured in advance by the user terminal. The selecting the uplink frequency point for uplink transmission in the uplink frequency point set according to the path loss of the downlink frequency point may include:

if the path loss of the downlink frequency point is greater than a preset threshold, selecting a target uplink frequency point in the uplink frequency point set as an uplink frequency point for uplink transmission, wherein the frequency of the target uplink frequency point is lower than the frequency of at least one other uplink frequency point in the uplink frequency point set;

and if the path loss of the downlink frequency point is not greater than a preset threshold, selecting any uplink frequency point in the uplink frequency point set as an uplink frequency point for uplink transmission.

For example: the path loss of the downlink frequency point is greater than the preset threshold, and the uplink frequency point with the lowest frequency in the uplink frequency point set can be selected as the frequency point for uplink transmission, so that the transmission performance of the downlink frequency point is ensured, and the uplink frequency point of 1.8GHz can be selected in the scenario shown in fig. 3. If the path loss of the downlink frequency point is not greater than the preset threshold, any uplink frequency point may be selected as the uplink frequency point for uplink transmission, and if the scenario is shown in fig. 3, the uplink frequency point of 1.8GHz or 3.5GHz may be selected, and the transmission performance of the downlink frequency point may be ensured.

And after the uplink frequency point is selected, the frequency point information of the selected uplink frequency point can be sent to the network side equipment.

Step 402, calculating the downlink loss based on the path loss compensation value, adding the downlink loss and the receiving target power of the uplink signal to obtain a reference power, and selecting the minimum power from the maximum transmitting power of the user terminal and the reference power as the transmitting power of the uplink signal.

Preferably, step 402 may calculate the transmission power of the uplink signal by the following formula:

PRACH_Preamble_Transmit_Power＝min{Pcmax,PL+PreambleRxTargetPower}

the PRACH _ Preamble _ Transmit _ Power indicates the transmission Power of the uplink signal, Pcmax is the maximum transmission Power of the ue, PL is the downlink loss, and Preamble rxtargetpower is the reception target Power of the uplink signal, and preferably, the reception target Power of the uplink signal may be the network side device reception target Power of the uplink signal, and may be determined by a parameter such as initial rx targetpower (initial rxtargetpower) in the SIB2 information. For example: PreambleRxTargetPower ═ initialraxtargetpower + (preambletransmissioncounter-1) — PowerRampingStep, where preambletransmissioncounter is the preamble transmission count value, PowerRampingStep is the power adjustment step, and preambletransmissioncounter and PowerRampingStep can be configured by higher layer signaling, preambletransmissioncounter ═ 1 at the first transmission.

The downlink loss can be calculated based on the path loss compensation value through step 402, and the transmission power of the uplink signal is calculated by combining the received target power of the uplink signal and the maximum transmission power of the user terminal, so that the accuracy of the transmission power of the uplink signal can be improved.

Optionally, the calculating the downlink loss based on the path loss compensation value includes:

and subtracting the reference signal receiving power measured by the user terminal from the reference signal transmitting power of the network side equipment acquired in advance to obtain a power difference value, and subtracting the path loss compensation value from the power difference value to obtain a result as the downlink loss.

In this embodiment, the downlink loss can be calculated by the following formula:

PL＝ReferenceSignalTransmitPower-RSRP measurment-PLoffset

wherein PL represents a downlink loss, Reference Signal transmit Power represents Reference Signal transmission Power of a network side device acquired in advance, RSRP measurement represents Reference Signal Receiving Power (RSRP) measured by a user, specifically, downlink RSRP, and PLoffset represents the above-mentioned path loss compensation value.

In this embodiment, the accuracy of the downlink loss is improved because the downlink loss is calculated from the reference signal transmission power, the reference signal reception power, and the path loss compensation value. Of course, in the embodiment of the present invention, the calculation of the downlink loss based on the path loss compensation value is not limited to be obtained by the above calculation method, and the downlink loss may also be determined according to the corresponding relationship between the path loss compensation value and the downlink loss, which is not limited to this embodiment of the present invention.

In this embodiment, the downlink loss can be calculated based on the path loss compensation value, and the transmit power of the uplink signal is calculated by combining the received target power of the uplink signal and the maximum transmit power of the user terminal, so that the accuracy of the transmit power of the uplink signal can be improved.

a first preset value corresponding to the downlink frequency point and the uplink frequency point, wherein the first preset value is configured for at least two user terminals by the network side equipment; or
