As the demand for mobile communication services has changed, organizations such as ITU (International telecommunications Union) and 3GPP (3rd Generation Partnership Project) have begun to research NR (New RAT), for example, 5G NR (5Generation New RAT), a fifth Generation wireless communication system. Currently, there is no specific scheme for controlling the uplink power for the future NR.

In an LTE (Long Term Evolution) wireless communication system, power Control may be performed on a PUCCH (Physical Uplink Control CHannel) in a slot i on a carrier c by the following formula:

wherein, Delta_{PUCCH_TF,c}(i) Represents a power adjustment value of the PUCCH, the adjustment value being related to a transmission format of the PUCCH.

Since NR and LTE PUCCH formats differ in terms of bit range, coding scheme, and the like, the LTE PUCCH power control scheme cannot be applied to NR. If reuse of delta in LTE in NR_{PUCCH_TF,c}(i) May degrade the transmission performance of the PUCCH in NR.

step 101, obtaining an uplink transmission parameter corresponding to an uplink channel format.

In this step, the mobile communication terminal may obtain an uplink transmission parameter corresponding to the uplink channel format.

The uplink channel format is an uplink channel format in the NR, and the uplink transmission parameters acquired by the mobile communication terminal may be different for different uplink channel formats.

And 102, calculating an uplink power adjustment value according to the uplink transmission parameters so as to realize the control of the uplink power.

In this step, the mobile communication terminal may calculate an uplink power adjustment value according to the uplink transmission parameter obtained in step 101, where the uplink power adjustment value is used to implement control of uplink power.

Specifically, how to implement the control of the uplink power by using the uplink power adjustment value may be implemented by using the uplink power control in LTE described in the background art, and in order to avoid repetition, this is not described in detail in the embodiments of the present invention.

The embodiment of the invention is suitable for controlling the uplink transmission power of the mobile communication terminal in the NR, and the embodiment of the invention calculates the uplink power adjustment value by acquiring the uplink transmission parameter corresponding to the uplink channel format in the NR, so that the calculated uplink power adjustment value can be adapted to the uplink channel format in the NR, the control of the uplink power is adapted to the uplink channel format in the NR, and the transmission performance of the uplink channel in the NR is ensured.

In NR, five new PUCCH formats are supported, which are: PUCCH format 0, i.e., short PUCCH formats of 2 bits and less than 2 bits; PUCCH format 1, i.e., 2-bit and 2-bit or less long PUCCH formats; PUCCH format 2, i.e., a short PUCCH format of 2 bits or more; PUCCH format 3, which is a long PUCCH format with 2 or more bits and does not support multi-user multiplexing; PUCCH format 4, i.e., a long PUCCH format of 2 bits or more, and supports multi-user multiplexing. The various PUCCH formats described above should not be so named as to limit the scope of the present invention.

The following specifically describes embodiments in which the present invention is adapted to different PUCCH formats in NR.

and step 1011, acquiring the number of symbols occupied by the first PUCCH format.

The embodiment of the present invention is applicable to a first PUCCH format, where the first PUCCH format is a short PUCCH format with 2 bits or less, and as can be understood, the first PUCCH format is PUCCH format 0 in five PUCCH formats in the above NR.

In this step, the mobile communication terminal may acquire the number of symbols occupied by the first PUCCH format.

And 1021, calculating an uplink power adjustment value according to the number of symbols occupied by the first PUCCH format so as to realize the control of the uplink power.

In this step, the mobile communication terminal may calculate an uplink power adjustment value according to the number of symbols occupied by the first PUCCH format acquired in step 1011.

As to how to implement the control of the uplink power by the uplink power adjustment value, reference may be made to the related description in the embodiment of the present invention shown in fig. 1, and details are not described here to avoid repetition.

Specifically, the calculation of the uplink power adjustment value in step 1021 can be implemented by the following formula:

wherein, Delta_{PUCCH_TF,c}(i) For the value of the uplink power adjustment,

Optionally, the N is_refThe value of (a) is a preset value or a value configured for higher layer signaling. If N is present_refIs a predetermined value, then N_refMay be, but is not limited to, 1.

For example, suppose that the base station instructs the mobile communication terminal to perform uplink feedback by using PUCCH format 0, the number of bits that need to be fed back is 1, and the number of symbols occupied by PUCCH format 0 is 1.

The mobile communication terminal may be according to the formula

Calculating a power adjustment value corresponding to the PUCCH format 0,

N_ref＝1，Δ_{PUCCH_TF,c}(i)＝10log₁₀(1)＝0dB。

therefore, the control of the uplink power is adapted to the PUCCH format 0 in the NR, so that the transmission performance of the PUCCH format 0 in the NR is ensured.

Referring to fig. 3, fig. 3 is a flowchart of another uplink power control method according to an embodiment of the present invention, and as shown in fig. 3, the uplink power control method includes the following steps:

wherein, Delta_{PUCCH_TF,c}(i) For the value of the uplink power adjustment,

the number of symbols occupied for the second PUCCH format,

Optionally, the N is_refThe value of (a) is a preset value or a value configured for higher layer signaling. If N is present_refIs a predetermined value, then N_refMay be, but is not limited to, 2.

The mobile communication terminal may be according to the formula

The number of bits of the UCI may be greater than 2 and equal to or less than 11, and the number of bits of the UCI may also be greater than 11.

Specifically, for the bit number of the UCI greater than 2 and less than or equal to 11, the calculation of the uplink power adjustment value in step 1023 can be implemented by the following formula:

the number of symbols occupied for the third PUCCH format,

and k is a preset value for the bandwidth occupied by the third PUCCH format.

For the number of bits of the UCI greater than 11, the calculation of the uplink power adjustment value in step 1023 can be implemented by the following formula:

the number of symbols occupied for the third PUCCH format,

bandwidth occupied for the third PUCCH format, p (N)_RE) Gain-related function for polarization polor coding, p (N)_RE) It may be a linear function or a nonlinear function.

For example, assuming that the base station instructs the mobile communication terminal to perform uplink feedback by using the PUCCH format 2, the number of UCI bits to be fed back is 5, the number of symbols occupied by the PUCCH format 2 is 2, and the number of occupied PRBs (Physical Resource Block) is 4, that is, the bandwidth occupied by the PUCCH format 2 is 4

The mobile communication terminal may be according to the formula

In this step, the mobile communication terminal may obtain the number of UCI bits corresponding to the third PUCCH format, the number of REs carrying UCI, and the frequency hopping configuration parameter of the third PUCCH format.

The frequency hopping configuration parameter is a parameter for configuring a PUCCH to enable frequency hopping, or the frequency hopping configuration parameter is a parameter for configuring the PUCCH not to enable frequency hopping.

And step 1024, calculating an uplink power adjustment value according to the bit number of the UCI, the number of the REs and the frequency hopping configuration parameter of the third PUCCH format, so as to realize the control of the uplink power.

In this step, the mobile communication terminal may calculate an uplink power adjustment value according to the number of bits of the UCI, the number of REs, and the frequency hopping configuration parameter of the third PUCCH format, which are acquired in step 1014. The number of bits of the UCI may be greater than 2 and equal to or less than 11, and the number of bits of the UCI may also be greater than 11.

Specifically, for the bit number of the UCI greater than 2 and less than or equal to 11, the calculation of the uplink power adjustment value in step 1024 may be implemented by the following formula:

In this embodiment, for the case that the value of k is related to the hopping configuration parameter of the third PUCCH format, the following is taken as an example:

for example, assuming that the base station instructs the mobile communication terminal to perform uplink feedback by using PUCCH format 2 without frequency hopping turned on, the number of UCI bits to be fed back is 5, the number of symbols occupied by PUCCH format 2 is 2, and the number of PRBs (Physical Resource blocks) occupied is 4, that is, the bandwidth occupied by PUCCH format 2 is 4
