In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific examples. The following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them belong to the protection scope of the embodiments of the present application. The embodiment of the present application includes at least part of the following contents.

In related technologies, the UE adjusts the number of PRBs occupied by PUCCH resources according to the number of bits of uplink control information actually sent, so as to improve spectrum efficiency. However, in high-frequency communication scenarios, since the transmission power of PUCCH needs to further consider the regulatory restrictions, for example, the maximum power spectral density (power spectral density, PSD) and equivalent isotropically radiated power (equivalent isotropically radiated power, EIRP) restrictions, this The maximum allowable transmit power corresponding to different PRB numbers is different.

Therefore, in high-frequency scenarios, if the number of PRBs occupied by PUCCH resources is still adjusted according to the number of bits of uplink control information, the transmission power of PUCCH may be affected, resulting in limited coverage performance.

FIG. 2 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. The method 200 can be executed by a terminal device in the communication system shown in FIG. 1. As shown in FIG. 2, the method 200 includes the following content :

S210. The terminal device determines the number of target physical resource block PRBs used to transmit the physical uplink control channel PUCCH according to the first information, where the first information includes the first number of PRBs and/or the target transmission power, and the first PRB The number is determined according to a high-level parameter, and the target transmit power is determined according to the first number of PRBs.

It should be understood that the embodiment of the present application may be applicable to a high-frequency frequency band, such as 52.6 GHz to 71 GHz, or may also be used to determine the number of PRBs occupied by PUCCH resources in any coverage performance limited scenario.

In some embodiments, the first number of PRBs is the maximum number of PRBs occupied by PUCCH transmission.

In some embodiments, the first number of PRBs is configured through radio resource control (Radio Resource Control, RRC) signaling, for example, the first number of PRBs is determined according to a high-layer parameter (for example, nrofPRBs), which is denoted as

In some embodiments, the format of the PUCCH is PUCCH format 2, PUCCH format 3 or PUCCH format 4.

In some embodiments, the terminal device directly determines the first number of PRBs as the target number of PRBs used for transmitting the PUCCH, regardless of the number of bits of the uplink control information carried in the PUCCH.

In some embodiments, the target transmit power is a transmit power determined according to a configurable maximum transmit power of the terminal device, a preset rule, the first number of PRBs, and a channel condition of the terminal device.

For example, the terminal device determines the first transmit power according to the first number of PRBs and channel conditions of the terminal device.

For example, the terminal device determines the second transmission power according to the first number of PRBs and a preset rule, for example, the second transmission power is the maximum transmission power corresponding to the first number of PRBs that satisfies the preset rule.

Further, the target transmit power is determined according to the first transmit power, the second transmit power and a configurable maximum transmit power of the terminal device.

For example, the target transmit power is the minimum value among the first transmit power, the maximum transmit power configurable by the terminal device, and the second transmit power.

In some embodiments, the maximum transmit power configurable by the terminal device is predefined, which is denoted as P _UEMAX,f,c . The configurable maximum transmit power of the terminal equipment takes into account the total radiated power (TRP) and EIRP limitations.

In some embodiments, if the terminal device uses the PUCCH power control adjustment state with the index 1 to send the PUCCH on the uplink active bandwidth part (Bandwidth, BWP) b of the carrier f in the primary cell c, the terminal device determines to send the PUCCH at the timing i The target transmit power _PUCCH,b,f,c (i,q _u ,q _d ,l) of the PUCCH in is:

Wherein, P1 represents the first transmit power, which can be specifically determined according to the following formula (2):

Among them, P _{O_PUCCH,b,f,c} (q _u ): a parameter consisting of the sum of the components P _{O_NOMINAL_PUCCH} and P _{O_UE_PUCCH} (q _u );

PUCCH resource allocation bandwidth represented by the number of PRBs;

μ: Pre-defined subcarrier spacing (Subcarrier spacing, SCS) configuration;

PL _b,f,c (q _d ): the path loss estimated by the UE using the reference signal resource index q _d , in dB;

Δ _{F_PUCCH} (F): high layer configuration parameters;

Δ _TF,b,f,c (i) is the PUCCH transmission power adjustment component, and there are different designs for different PUCCH formats;

g _b,f,c (i,l) is the PUCCH power control adjustment state, and

Used to implement closed-loop adjustment of power control, where δ _PUCCH,b,f,c (i,l) is a transmission power control (Transmission Power Control,TPC) command carried in downlink control information (Downlink Control Information,DCI).

In some embodiments, the _PCMAX,f,c (i) is determined according to the maximum transmit power and the second transmit power configurable by the terminal device.

For example, P _CMAX,f,c (i) is determined according to the following formula (3):

Wherein, P _UEMAX,f,c represents the maximum transmit power configurable by the terminal device, and the second transmit power represents the maximum transmit power corresponding to the first number of PRBs satisfying the preset rule.

That is, in the embodiment of this application, the target transmit power of PUCCH not only considers the maximum transmit power configurable by the UE, but also considers the maximum transmit power limited by the preset rules. Wherein, the maximum transmission power limited by the preset rule is related to the number of PRBs.

In some embodiments, the preset rules may include national regulatory requirements and/or frequency spectrum usage specifications, for example, resource usage specifications on unlicensed spectrum. For example, in order to avoid causing strong interference to other systems using unlicensed spectrum resources, the maximum transmit power or maximum transmit power spectral density of terminal equipment using unlicensed spectrum resources is usually limited.

The following describes how to determine P _RegMAX in combination with the specific rules of each country.

For European regulatory requirements, P _RegMAX is limited to:

Among them, 40dBm-TxBF is the EIRP limit, 23dBm/MHz+max(0,10*log10(BW))-TxBF is the PSD limit, BW is the PUCCH transmission bandwidth, and TxBF is the beamforming gain. Figure 3 shows the impact of the PSD limit and EIRP limit on the maximum allowable transmit power under different bandwidths represented by the number of RBs under European regulations.

For US regulatory requirements, P _RegMAX limits are:

Among them, 40dBm-TxBF is the EIRP limit, 27dBm–max(0,10*log10(100/BW)) is the PSD limit, BW is the PUCCH transmission bandwidth, and TxBF is the beamforming gain. Figure 4 shows the impact of the PSD limit and EIRP limit on the maximum allowable transmit power under different bandwidths represented by the number of RBs under the US regulations.

For Korean regulatory requirements, when the device is less than 300 meters, the P _RegMAX limit is:

Among them, 27dBm-TxBF is the EIRP limit, 13dBm/MHz+max(0,10*log10(BW))-TxBF is the PSD limit, BW is the PUCCH transmission bandwidth, and TxBF is the beamforming gain. Figure 5 shows the impact of the PSD limit and EIRP limit on the maximum allowable transmit power under different bandwidths represented by the number of RBs when the device is less than 300 meters under Korean regulations.

When the device is greater than 300 meters, the P _RegMAX limit is:

Among them, 43dBm–TxBF is the EIRP limit, 13dBm/MHz+max(0,10*log10(BW))-TxBF is the PSD limit, BW is the PUCCH transmission bandwidth, and TxBF is the beamforming gain. Figure 6 shows the impact of the PSD limit and EIRP limit on the maximum allowable transmit power under different bandwidths represented by the number of RBs when the device is greater than 300 meters under Korean regulations.

As can be seen from the above, for different regions, the maximum transmit power allowed by regulations is related to the bandwidth. Before the EIRP limit is reached, the maximum allowable transmit power is different under different bandwidths, and the larger the bandwidth, the greater the maximum allowable transmit power. It can be seen that in a high-frequency scenario, adjusting the number of PRBs occupied by the PUCCH will affect the maximum allowable transmission power of the PUCCH, so it is necessary to restrict the behavior of the terminal device to adjust the number of PRBs occupied by the PUCCH.

In some embodiments of this application, S210 includes:

The terminal device determines the target number of PRBs according to the first information and the number of bits of uplink control information carried in the PUCCH.

That is, in the embodiment of the present application, the terminal device considers the first number of PRBs, the target transmission power of the PUCCH, and the number of bits of the uplink control information in the PUCCH to determine the target number of PRBs for PUCCH transmission, which is beneficial to both the transmission of the uplink control information and the number of bits of uplink control information in the PUCCH. PUCCH transmission power, so as to ensure coverage performance and spectrum efficiency.

As an example but not a limitation, the uplink control information may include at least one of the following:

Hybrid Automatic Repeat request Acknowledgment (HARQ-ACK) information;

Scheduling Request (SR);

Channel State Information (CSI).

In some embodiments, the CSI may include wideband (wideband) CSI and/or subband (subband) CSI.

In some embodiments, the terminal device determines the target number of PRBs according to the first information and the number of bits of the uplink control information carried in the PUCCH, including:

Determine the target number of PRBs according to the number of bits of the uplink control information and the number of information bits that can be carried by the first PUCCH resource configuration, where the first PUCCH resource configuration includes the first number of PRBs

In some embodiments, the first PUCCH resource configuration also includes

Q _m and r. in,

Indicates the number of subcarriers occupied by the uplink control information on each PRB,

Indicates the number of symbols occupied by the uplink control information, Q _m indicates the modulation scheme of the PUCCH, and r indicates the maximum code rate that can be used for transmitting the uplink control information.

In some embodiments, the parameters included in the first PUCCH resource configuration are configured through RRC, for example, through high layer parameter configuration.

In some embodiments, the number of information bits that can be carried by the first PUCCH resource configuration is according to the formula

Sure.

Case 1: the number of bits of the uplink control information is less than the number of information bits that can be carried by the first PUCCH resource configuration.

Implementation method 1:

If the number of bits of the uplink control information is less than the number of information bits that can be carried by the first PUCCH resource configuration, determine the first number of PRBs as the target number of PRBs, where the first PUCCH resource configuration includes the first PUCCH resource configuration A number of PRBs.

When the number of bits of the uplink control information is less than the number of information bits that can be carried by the first PUCCH resource configuration, the terminal device still uses the maximum number of PRBs used for PUCCH transmission, that is, the first number of PRBs to perform PUCCH transmission. In this way, according to the foregoing The target transmission power of the PUCCH determined by formula (1) remains unchanged, which is beneficial to ensure coverage performance and improve spectrum efficiency at the same time.

Optionally, the number of subcarriers occupied by the terminal device for transmitting uplink control information on each PRB is determined according to the high-level parameters

It is determined that the number of symbols occupied by the uplink control information is based on the high-level parameter

Determined, the modulation scheme of the PUCCH is determined according to the high layer parameter Q _m .

Since the number of bits of the uplink control information in the PUCCH is lower than the carrying capacity of the first PUCCH resource configuration, the bit number of the uplink control information needs to be rate-matched against the first PUCCH resource configuration to obtain the code rate actually used to transmit the uplink control information , since the number of PRBs is not adjusted, the code rate for transmitting uplink control information is reduced, so that transmission reliability and coverage performance can be further improved.

In the embodiment of the present application, the method 200 further includes:

Determine the code rate used for transmitting the uplink control information according to the number of bits of the uplink control information and the first PUCCH resource configuration.

For example, the terminal device may determine the code rate used by the terminal device to transmit the uplink control information according to the following formula (4):

Wherein, O _UCI represents the number of bits of the uplink control information,

Indicates the first PRB number,

Represents the number of symbols occupied by the uplink control information, Q _m represents the modulation scheme of the PUCCH,

Indicates the code rate used for transmitting the uplink control information.

According to the aforementioned formula (1) of the target transmit power of PUCCH, it can be seen that without adjusting the number of PRBs occupied by PUCCH (that is, using the first PRB number), the target transmit power of PUCCH remains unchanged, and the code rate after rate matching Therefore, the transmission reliability can be further improved and the coverage performance can be improved.

Implementation 2:

If the number of bits of the uplink control information is less than the number of information bits that can be carried by the first PUCCH resource configuration, determine the second number of PRBs as the number of target PRBs, where the second number of PRBs is less than or equal to the first number of PRBs The number of PRBs, the first PUCCH resource configuration includes the first number of PRBs.

In this embodiment of the present application, the size of the second PRB number is designed not to affect the transmission power of the PUCCH, that is, the transmission power of the PUCCH determined according to the first PRB number and the maximum PUCCH transmission power determined according to the second PRB number Send power is the same.

For example, calculated according to formula (1)

The target transmit power of the corresponding PUCCH is the aforementioned first transmit power, or the maximum transmit power configurable by the terminal device.

As an example,

express

The corresponding maximum allowable transmission power is not lower than that calculated according to formula (1)

The target transmission power of the corresponding PUCCH. Therefore, when the number of bits of the uplink control information is less than the number of information bits that can be carried by the first PUCCH resource configuration, the terminal device performs PUCCH transmission with the second PRB number without affecting the transmission of the PUCCH power, i.e. the terminal equipment can still be calculated using the formula (1)

Sending the PUCCH at the corresponding target transmission power of the PUCCH is beneficial to ensure coverage performance and improve spectrum efficiency at the same time.

In this implementation manner 2, the number of target PRBs includes the second number of PRBs starting from the first PRB in the first number of PRBs. That is, the terminal equipment is actually used to transmit PUCCH
