Please refer to FIG. 2. FIG. 2 is a flowchart of a power configuration method provided by an embodiment of the present invention. The method is applied to a terminal, as shown in FIG. 2, and includes the following steps:

Step 201, receive power configuration, the power configuration includes:

The first transmit power of each SS-PBCH-Block in multiple SS-PBCH-Blocks; or

The second transmit power of the SS-PBCH-Block configured in units of cells, and the offset between the third transmit power of each SS-PBCH-Block in the multiple SS-PBCH-Blocks and the second transmit power.

Step 201 may be to receive the above power configuration sent by the network device, for example: receive the above power configuration configured by the network device through a broadcast channel, or receive the above power configuration configured by a high layer of the network device. In addition, the above multiple SS-PBCH-Blocks may be all or part of the SS-PBCH-Blocks that the network device can send, or may be multiple SS-PBCH-Blocks corresponding to multiple beams of the network device.

The first transmission power of each SS-PBCH-Block in the above-mentioned plurality of SS-PBCH-Blocks can be that the transmission power is configured in units of SS-PBCH-Blocks, for example: different transmission powers are configured for different SS-PBCH-Blocks, of course, the same transmission power can also be configured for certain SS-PBCH-Blocks, and different transmission powers can be configured for other SS-PBCH-Blocks.

Wherein, the above-mentioned second transmission power of the SS-PBCH-Block configured in units of cells may be the transmission power of the corresponding SS-PBCH-Block configured for each cell, that is, the transmission power of the cell-level SS-PBCH-Block is configured, and the transmission power of one SS-PBCH-Block is configured for one cell. For example, if a certain network device has 3 cells, the second transmit power of 3 SS-PBCH-Blocks can be configured for the 3 cells respectively.

For the offset between the third transmission power of each SS-PBCH-Block in the plurality of SS-PBCH-Blocks and the second transmission power, the third transmission power of each SS-PBCH-Block in the plurality of SS-PBCH-Blocks may be configured with the third transmission power in units of SS-PBCH-Blocks, and the offset of the second transmission power may be configured with different offsets for different SS-PBCH-Blocks. Of course, the same offset may also be configured for some SS-PBCH-Blocks, and Configure different offsets for other SS-PBCH-Blocks.

The third transmission power of the above SS-PBCH-Block may be based on the second transmission power of the SS-PBCH-Block configured in units of cells, and then configure the third transmission power for each SS-PBCH-Block in the cell.

It should be noted that the above "or" means that in one case the above power configuration includes: the first transmit power of each SS-PBCH-Block in multiple SS-PBCH-Blocks; in another case the above power configuration includes: the second transmit power of the SS-PBCH-Block configured in units of cells, and the offset between the third transmit power of each SS-PBCH-Block in the multiple SS-PBCH-Blocks and the second transmit power.

In the embodiment of the present invention, each SS-PBCH-Block can be individually configured with transmit power, and/or, each SS-PBCH-Block can be individually configured with an offset from the above-mentioned second transmit power, which can support flexible configuration of network coverage to improve network coverage.

As an optional implementation, the method also includes:

determining a first path loss value according to a higher layer filtered first reference signal received power (higher layer filtered RSRP) and a first reference signal transmitted power, wherein the first reference signal transmitted power corresponds to the first transmitted power of the first SS-PBCH-Block or the third transmitted power of the first SS-PBCH-Block, and the first reference signal received power corresponds to the received power of the first SS-PBCH-Block;

The first SS-PBCH-Block is any SS-PBCH-Block in the multiple SS-PBCH-Blocks.

Since the first SS-PBCH-Block is any SS-PBCH-Block in the plurality of SS-PBCH-Blocks, the above-mentioned step of determining the first path loss value may be realized by determining the corresponding first path loss value for each SS-PBCH-Block, so as to obtain the first path loss value of each SS-PBCH-Block.

It should be noted that, in the embodiment of the present invention, there is a one-to-one correspondence between beams and SS-PBCH-Blocks, that is, one beam corresponds to one specific SS-PBCH-Block. For example: beam 1 corresponds to SS-PBCH-Block1, beam 2 corresponds to SS-PBCH-Block2, and beam 3 corresponds to SS-PBCH-Block3. Specifically, each beam corresponds to an SS-PBCH-Block identifier. Therefore, in the embodiment of the present invention, the transmit power of each SS-PBCH-Block may also be referred to as the transmit power of each beam, that is, beam-level transmit power, and the offset between the third transmit power and the second transmit power of each SS-PBCH-Block may also be referred to as the offset between the third transmit power and the second transmit power of each beam. In addition, in the embodiment of the present invention, the SS-PBCH-Block may be referred to as SSB or SS/PBCH block for short.

It should be noted that the reference signal in the embodiment of the present invention may be a known signal provided by the transmitting end to the receiving end for channel estimation or channel detection.

The correspondence between the received power of the first reference signal and the received power of the SS-PBCH-Block may be pre-configured. For example: the received power of the first reference signal may be the received power of the SS-PBCH-Block.

The correspondence between the first reference signal transmission power and the first transmission power or the third transmission power of the SS-PBCH-Block may be pre-configured. Preferably, the first reference signal transmission power is the first transmission power of the first SS-PBCH-Block or the third transmission power of the first SS-PBCH-Block. For example: when the terminal is not configured to receive periodic Channel State Information-Reference Signal (CSI-RS), the first reference signal transmission power is the first transmission power or the third transmission power of the first SS-PBCH-Block.

Certainly, in the embodiment of the present invention, the corresponding relationship between the first reference signal transmission power and the first transmission power or the third transmission power of the SS-PBCH-Block is not limited, for example: the above-mentioned first reference signal transmission power is: the first transmission power of the first SS-PBCH-Block plus the offset between the first transmission power of the first SS-PBCH-Block and the CSI-RS power, the third transmission power of the first SS-PBCH-Block plus the offset between the third transmission power of the first SS-PBCH-Block and the CSI-RS power quantity. Wherein, the above CSI-RS power may be the transmission power of the CSI-RS.

It should be noted that, when the offset between the first transmit power or the third transmit power of the SS-PBCH-Block and the CSI-RS power is not provided to the terminal, the terminal assumes that the first transmit power of the first SS-PBCH-Block or the offset between the third transmit power and the CSI-RS power is 0dB.

Preferably, in the case that the terminal is configured to receive periodic CSI-RS, the above-mentioned first reference signal transmission power is: the first transmission power or the third transmission power of the first SS-PBCH-Block plus the offset between the first transmission power or the third transmission power of the first SS-PBCH-Block and the CSI-RS power.

The above-mentioned determining the first path loss value based on the first reference signal received power and first reference signal transmit power filtered by the high layer may be calculating the first path loss value based on the first reference signal received power and the first reference signal transmit power filtered by the high layer. In this implementation manner, since the first path loss value is determined according to the first reference signal received power and the first reference signal transmitted power, the path loss value is more accurate.

For example: Since the beam and SS-PBCH-Block have a one-to-one correspondence, the path loss of each beam can be calculated by the following formula:

referenceSignalPower(i) = ss-PBCH-BlockPower(i)

PL(i)=referenceSignalPower(i)–higher layer filtered RSRP

Wherein, i corresponds to each beam, that is, the above PL(i) may refer to the path loss of beam i;

The above referenceSignalPower(i) represents the first reference signal transmission power of beam i, the above ss-PBCH-BlockPower(i) represents the first transmission power of the SS-PBCH-Block corresponding to beam i or the third transmission power of the SS-PBCH-Block corresponding to beam i, and the above higher layer filtered RSRP represents the first reference signal reception power of high layer filtering.

For example: Since the beam and SS-PBCH-Block have a one-to-one correspondence, the path loss of each beam can be calculated by the following formula:

referenceSignalPower(i)=ss-PBCH-BlockPower(i)+powerControlOffsetSS(i)

PL(i)=referenceSignalPower(i)–higher layer filtered RSRP

Wherein, the above powerControlOffsetSS(i) represents the power offset corresponding to the beam i, for example: the offset between the first transmit power of the SS-PBCH-Block corresponding to the beam i and the CSI-RS power, and the offset between the third transmit power of the SS-PBCH-Block corresponding to the beam i and the CSI-RS power.

In the above embodiment, since the transmission power is configured for each SS-PBCH-Block, and the SS-PBCH-Block corresponds to the beam, the SS-PBCH-Block power configuration based on a specific beam (beam specific) can be realized in this way, thereby supporting the separate configuration of coverage for each beam. For example, as shown in FIG.

Optionally, the third transmit power of each SS-PBCH-Block may be the transmit power determined according to the second transmit power and an offset between the third transmit power of the SS-PBCH-Block and the second transmit power.

As an optional implementation, the above method also includes:

Determine a second path loss value according to the second reference signal received power and the second reference signal transmitted power filtered by the high layer, wherein the second reference signal transmitted power corresponds to at least one of the following items: an offset between the third transmitted power of the second SS-PBCH-Block and the second transmitted power, and the second transmitted power;

The second SS-PBCH-Block is any SS-PBCH-Block in the multiple SS-PBCH-Blocks.

Optionally, the second reference signal received power corresponds to the received power of the second SS-PBCH-Block, for example: the second reference signal received power is the received power of the second SS-PBCH-Block.

Since the second SS-PBCH-Block is any SS-PBCH-Block in the plurality of SS-PBCH-Blocks, the above step of determining the second path loss value may be to determine the corresponding second path loss value for each SS-PBCH-Block, so as to obtain the second path loss value of each SS-PBCH-Block.

In this embodiment, it may be implemented when the above power configuration includes the second transmit power of the SS-PBCH-Block configured in units of cells, and the offset between the third transmit power of each SS-PBCH-Block in the multiple SS-PBCH-Blocks and the second transmit power.

The second reference signal transmission power may correspond to the second transmission power, and correspond to an offset between the third transmission power of the second SS-PBCH-Block and the second transmission power. Preferably, the second reference signal transmission power is the second transmission power plus an offset between the third transmission power of the second SS-PBCH-Block and the second transmission power. For example: when the terminal is not configured to receive periodic CSI-RS, the second reference signal transmission power is the second transmission power plus an offset between the third transmission power of the second SS-PBCH-Block and the second transmission power.

Of course, in the embodiment of the present invention, the second reference signal transmission power may also be: the offset between the third transmission power of the second SS-PBCH-Block and the second transmission power, the second transmission power, and the sum of the offset between the third transmission power of the second SS-PBCH-Block and the CSI-RS power. For example: in the case where the terminal is configured to receive periodic CSI-RS, the transmission power of the second reference signal is: the offset between the third transmission power of the second SS-PBCH-Block and the second transmission power, the second transmission power, and the sum of the offset between the third transmission power of the second SS-PBCH-Block and the CSI-RS power.

In this implementation manner, since the second path loss value is determined according to the second reference signal received power and the second reference signal transmitted power, the path loss value is more accurate.

For example: Since the beam and SS-PBCH-Block have a one-to-one correspondence, the path loss of each beam can be calculated by the following formula:

referenceSignalPower(i)=ss-PBCH-BlockPower+BeamSpecificPowerOffset(i)

PL(i)=referenceSignalPower(i)–higher layer filtered RSRP

Wherein, i corresponds to each beam, that is, the above PL(i) may refer to the path loss of beam i;

The above referenceSignalPower(i) represents the second reference signal transmission power of the beam i, the above ss-PBCH-BlockPower represents the second transmission power of the SS-PBCH-Block of the cell, the above BeamSpecificPowerOffset(i) represents the offset between the third transmission power of the SS-PBCH-Block corresponding to the beam i and the above second transmission power, and the above higher layer filtered RSRP represents the second reference signal reception power of high layer filtering.

Another example: Since beams and SS-PBCH-Blocks have a one-to-one correspondence, the path loss of each beam can be calculated by the following formula:

referenceSignalPower(i)=ss-PBCH-BlockPower+powerControlOffsetSS(i)+BeamSpecificPowerOffset(i)

PL(i)=referenceSignalPower(i)–higher layer filtered RSRP

Wherein, the powerControlOffsetSS(i) above represents an offset between the third transmit power of the SS-PBCH-Block corresponding to the beam i and the CSI-RS power.

In the above-mentioned embodiment, since the second transmission power of the SS-PBCH-Block of each cell can be configured, and the offset between the third transmission power and the second transmission power of each SS-PBCH-Block, it is possible to realize the SS-PBCH power configuration based on the specific cell (cell specific) + specific beam power offset (beam specific power offset), thereby supporting the separate configuration of coverage for each beam of different cells. Flexible configuration of network coverage.

As an optional implementation manner, the above power configuration includes:

The second transmission power of the SS-PBCH-Block configured in units of cells;

A power control parameter for each of the plurality of beams.

Wherein, the aforementioned power control parameters may be uplink power control parameters (UL PC parameters). The foregoing power control parameter may be an uplink channel of a beam or a power control parameter of a reference signal. In addition, in this embodiment of the present invention, the beam may be an uplink beam.

In the above embodiment, since the second transmit power of the SS-PBCH-Block of each cell and the power control parameters of each beam can be configured, the SS-PBCH power configuration based on specific cell (cell specific) + uplink power control parameters (UL PC parameters) can be realized, thereby supporting the separate configuration of coverage for each beam of different cells, thereby realizing flexible configuration of network coverage.

Similarly, this embodiment can also determine the path loss of the beam, for example:

Determine a third path loss value according to the third reference signal received power and the third reference signal transmitted power filtered by the high layer, where the third reference signal transmitted power corresponds to the second transmitted power, and the third reference signal received power corresponds to the received power of the SS-PBCH-Block.

For example: in the case where the transmission power of the above-mentioned third reference signal is the above-mentioned second transmission power, specifically, in the case where the terminal is not configured to receive periodic CSI-RS, the path loss of the beam can be calculated by the following formula:

referenceSignalPower(i) = ss-PBCH-BlockPower

PL(i)=referenceSignalPower–higher layer filtered RSRP+ULPCParameterOffset(i)

Wherein, i corresponds to each beam, that is, the above PL(i) may refer to the path loss of beam i;

The above referenceSignalPower(i) represents the third reference signal transmission power of beam i, the above ss-PBCH-BlockPower represents the second transmission power of the SS-PBCH-Block of the cell, the above higherlayer filteredRSRP represents the third reference signal reception power of high layer filtering, and the above ULPCParameterOffset(i) represents the power control parameter of beam i.

For example: when the transmission power of the above-mentioned third reference signal is the above-mentioned second transmission power plus the first transmission power of the third SS-PBCH-Block or the offset between the third transmission power and the CSI-RS power, specifically, when the terminal is configured to receive periodic CSI-RS, the path loss of the beam can be calculated by the following formula:

referenceSignalPower(i)=ss-PBCH-BlockPower+powerControlOffsetSS(i)

PL(i)=referenceSignalPower(i)–higher layer filtered RSRP+ULPCParameterOffset(i)

Wherein, the above powerControlOffsetSS(i) represents the offset between the first transmit power of the SS-PBCH-Block corresponding to the beam i and the CSI-RS power, or represents the offset between the third transmit power of the SS-PBCH-Block corresponding to the beam i and the CSI-RS power, which will not be described here.

In the embodiment of the present invention, it is possible to flexibly configure network coverage, and in addition, it is also possible to accurately determine the path loss of each beam. In addition, the terminal can also perform communication operations according to the path loss of each beam, so as to realize that the communication operation of the terminal corresponds to the network coverage, so as to improve the communication capability of the terminal. Wherein, the communication operation includes, but is not limited to: determining the coverage of the beam, communication operation using path loss for data transmission, and the like.

The above-mentioned power configuration method provided by the embodiment of the present invention is illustrated below through multiple embodiments in three situations:

Case 1:

SS-PBCH (ie, SS-PBCH-Block) power configuration based on a specific beam (beam specific); for example, a network device configures transmission power for each SS-PBCH through a broadcast channel.

Option one: (embodiment one)

If the terminal does not configure periodic CSI-RS reception, the reference signal transmission power for path loss calculation is obtained by the high-layer configuration parameter: SS/PBCH (ss-PBCH-BlockPower) block power (for example: the first transmission power or the third transmission power of each SS-PBCH-Block), and the corresponding path loss calculation method is as follows:

referenceSignalPower(i) = ss-PBCH-BlockPower(i)

PL(i)=referenceSignalPower(i)–higher layer filtered RSRP

where i corresponds to each beam.

Scheme two: (embodiment two)

If the terminal configures periodic CSI-RS reception, the path loss calculation is based on the CSI-RS resource, and the reference signal transmission power is calculated by the parameter SS/PBCH block power configured by the upper layer, and the SS/PBCH block power and CSI-RS power offset (powerControlOffsetSS). The path loss calculation method is as follows:

referenceSignalPower(i)=ss-PBCH-BlockPower(i)+powerControlOffsetSS(i)

PL(i)=referenceSignalPower(i)–higher layer filtered RSRP

If the SS/PBCH block power and the CSI-RS power offset are not provided to the UE, the UE assumes that the power offset is 0 dB.

Case 2: SS-PBCH power configuration based on cell specific + beam specific power offset; for example, the network device can configure ss-PBCH-Block Power for each cell through the broadcast channel, and then configure different power offsets for different beams of each cell.

Scheme three: (embodiment three)

If the terminal is not configured to receive periodic CSI-RS, the reference signal transmission power for path loss calculation is obtained from the high-layer configuration parameter SS/PBCH block power. The corresponding path loss calculation method is as follows:

referenceSignalPower(i)=ss-PBCH-BlockPower+BeamSpecificPowerOffset(i)

PL(i)=referenceSignalPower(i)–higher layer filtered RSRP

Scheme four: (embodiment four)

If the terminal is configured to receive periodic CSI-RS, the path loss calculation is based on the CSI-RS resource. The reference signal transmission power is calculated from the parameter SS/PBCH block power configured by the upper layer, and the offset between the SS/PBCH block power and the CSI-RS power. The path loss calculation method is as follows:

referenceSignalPower(i)=ss-PBCH-BlockPower+powerControlOffsetSS(i)+BeamSpecificPowerOffset(i)

PL(i)=referenceSignalPower(i)–higher layer filtered RSRP

If the SS/PBCH block power and the CSI-RS power offset are not provided to the UE, the UE assumes that the power offset is 0 dB.

Case 3: SS-PBCH power configuration based on specific cell (cell specific) + uplink power control parameters (UL PC parameters); for example: the network device configures ss-PBCH-BlockPower for each cell through the broadcast channel, and then configures different offsets for different beams of each cell. The network device can configure different power control parameters for uplink channels or reference signals sent using different uplink beams through high-level signaling, such as: different P0 values, and different closed-loop power control adjustments.

Scheme five: (embodiment five)

If the terminal is not configured to receive periodic CSI-RS, the reference signal transmission power for path loss calculation is obtained from the high-layer configuration parameter SS/PBCH block power. The corresponding path loss calculation method is as follows:

referenceSignalPower(i) = ss-PBCH-BlockPower

PL(i)=referenceSignalPower–higher layer filtered RSRP+ULPCParameterOffset(i)

Scheme six: (embodiment six)

If the terminal is configured to receive periodic CSI-RS, the path loss calculation is based on the CSI-RS resource. The reference signal transmission power is calculated from the parameter SS/PBCH block power configured by the upper layer, and the offset between the SS/PBCH block power and the CSI-RS power. The path loss calculation method is as follows:

referenceSignalPower(i)=ss-PBCH-BlockPower+powerControlOffsetSS(i)

PL(i)=referenceSignalPower–higher layer filtered RSRP+ULPCParameterOffset(i)

If the SS/PBCH block power and the CSI-RS power offset are not provided to the UE, the UE assumes that the power offset is 0 dB.

The above power configuration method provided by the embodiment of the present invention can be implemented as follows:

1. The network device configures the corresponding power for each ss-PBCH-Block through the broadcast channel;

2. The network device configures the cell-level ss-PBCH-BlockPower through the broadcast channel, and configures different beam-level offsets for the second transmit power of each SS-PBCH-Block;

3. The network device configures cell-level ss-PBCH-BlockPower through the broadcast channel, and at the same time, configures different power control parameters for uplink channels or reference signals transmitted by different beams.
