Referring to fig. 2, fig. 2 is a flowchart of a power configuration method according to an embodiment of the present invention, where the method is applied to a terminal, as shown in fig. 2, and includes the following steps:
step 201, receiving a power configuration, wherein the power configuration comprises:
a first transmit power of each SS-PBCH-Block of the plurality of SS-PBCH-blocks; or alternatively
And an offset of the third transmission power of each SS-PBCH-Block of the plurality of SS-PBCH-blocks from the second transmission power.
Step 201 may be to receive the above power configuration sent by the network device, for example: the above power configuration of the network device configured by the broadcast channel is received, or the above power configuration of the network device higher-layer configuration is received. In addition, the plurality of SS-PBCH-blocks may be all or part of SS-PBCH-blocks that can be transmitted by the network device, or may be a plurality of SS-PBCH-blocks corresponding to a plurality of beams of the network device.
The first transmission power of each SS-PBCH-Block of the plurality of SS-PBCH-blocks may be configured by using SS-PBCH-Block as a unit, for example: different transmission powers are configured for different SS-PBCH-blocks, and of course, the same transmission power may be configured for some SS-PBCH-blocks, and different transmission powers may be configured for other SS-PBCH-blocks.
The second transmission power of the SS-PBCH-Block configured in the cell unit may be a transmission power of the SS-PBCH-Block configured for each cell, that is, a transmission power of the SS-PBCH-Block configured at the cell level, and a transmission power of the SS-PBCH-Block configured for one cell. For example: a network device has 3 cells, and the 3 cells may be respectively configured with the second transmission power of 3 SS-PBCH-blocks.
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 by using the SS-PBCH-Block as a unit, and the offset of the second transmission power may be configured by different offsets for different SS-PBCH-blocks, or of course, may be configured by the same offset for some SS-PBCH-blocks and configured by different offsets for other SS-PBCH-blocks.
The third transmission power of SS-PBCH-Block may be configured for each SS-PBCH-Block in the cell based on the second transmission power of SS-PBCH-Block configured in the cell unit.
It should be noted that the "or" indicates that in one case the above power configuration includes: a first transmit power of each SS-PBCH-Block of the plurality of SS-PBCH-blocks; in another case the above power configuration comprises: and an offset of the third transmission power of each SS-PBCH-Block of the plurality of SS-PBCH-blocks from the second transmission power.
In the embodiment of the invention, the independent configuration of the transmission power for each SS-PBCH-Block and/or the independent configuration of the offset of the second transmission power for each SS-PBCH-Block can be supported, so that the flexible configuration of the network coverage can be supported, and the network coverage effect can be improved.
As an alternative embodiment, the method further comprises:
determining a first path loss value according to a first reference signal receiving power (higher layer filtered RSRP) and a first reference signal transmitting power of high-layer filtering, wherein the first reference signal transmitting power corresponds to a first transmitting power of a first SS-PBCH-Block or a third transmitting power of the first SS-PBCH-Block, and the first reference signal receiving power corresponds to a receiving power of the first SS-PBCH-Block;
The first SS-PBCH-Block is any one of the plurality of SS-PBCH-blocks.
Because the first SS-PBCH-Block is any SS-PBCH-Block of the plurality of SS-PBCH-blocks, the step of determining the first path loss value may be implemented by determining, for each SS-PBCH-Block, a corresponding first path loss value to obtain a first path loss value of each SS-PBCH-Block.
In the embodiment of the present invention, the beams and SS-PBCH-Block are in one-to-one correspondence, 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 transmission power of each SS-PBCH-Block may also be referred to as the transmission power of each beam, that is, the transmission power of the beam level, and the offset of the third transmission power and the second transmission power of each SS-PBCH-Block may also be referred to as the offset of the third transmission power and the second transmission power of each beam. In addition, in the embodiment of the present invention, the SS-PBCH-Block may be simply referred to as an SSB or an SS/PBCH Block.
It should be noted that, in the embodiment of the present invention, the reference signal may be provided by the transmitting end to the receiving end for a known signal to be used for channel estimation or channel sounding.
The first reference signal received power may be preconfigured to correspond to the SS-PBCH-Block received power. For example: the first reference signal received power may be a received power of the SS-PBCH-Block.
The first reference signal transmission power may be preconfigured to correspond to the first transmission power or the third transmission power of the SS-PBCH-Block. Preferably, the first reference signal transmission power is a first transmission power of the first SS-PBCH-Block or a third transmission power of the first SS-PBCH-Block. For example: in the case that the terminal does not configure periodic channel state information Reference Signal (CSI-RS) reception, the first Reference Signal transmission power is the first transmission power or the third transmission power of the first SS-PBCH-Block.
Of course, in the embodiment of the present invention, the correspondence 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 first reference signal transmission power is: the first transmission power of the first SS-PBCH-Block is added with the offset of the first transmission power of the first SS-PBCH-Block and the offset of the CSI-RS power, and the third transmission power of the first SS-PBCH-Block is added with the offset of the third transmission power of the first SS-PBCH-Block and the offset of the CSI-RS power. The CSI-RS power may be a transmission power of a CSI-RS.
In the case where the offset between the first transmission power or the third transmission power of the SS-PBCH-Block and the CSI-RS power is not provided to the terminal, the terminal assumes that the offset between the first transmission power or the third transmission power of the first SS-PBCH-Block and the CSI-RS power is 0dB.
Preferably, when the terminal has configured periodic CSI-RS reception, the first reference signal transmission power may be: the first transmission power or the third transmission power of the first SS-PBCH-Block is added to the offset of the first transmission power or the third transmission power of the first SS-PBCH-Block and the CSI-RS power.
The determining the first path loss value according to the first reference signal received power and the first reference signal transmission power of the higher layer filtering may be calculating the first path loss value based on the first reference signal received power and the first reference signal transmission power of the higher layer filtering. In this embodiment, the first path loss value is determined according to the first reference signal received power and the first reference signal transmission power, so that the path loss value is more accurate.
For example: because the beams and the SS-PBCH-Block are in one-to-one correspondence, the path loss of each beam can be calculated through the following formula:
referenceSignalPower(i)＝ss-PBCH-BlockPower(i)
PL(i)＝referenceSignalPower(i)–higher layer filtered RSRP
Where i corresponds to each beam, i.e., PL (i) above may refer to the path loss of beam i;
the referenceSignalPower (i) indicates a first reference signal transmission power of a beam i, the SS-PBCH-Block power (i) indicates a first transmission power of an SS-PBCH-Block corresponding to the beam i or a third transmission power of an SS-PBCH-Block corresponding to the beam i, and the higher layer filtered RSRP indicates a first reference signal reception power of high layer filtering.
For example: because the beams and the SS-PBCH-Block are in one-to-one correspondence, the path loss of each beam can be calculated through the following formula:
referenceSignalPower(i)＝ss-PBCH-BlockPower(i)+powerControlOffsetSS(i)
PL(i)＝referenceSignalPower(i)–higher layer filtered RSRP
wherein powerControlOffsetSS (i) represents the power offset corresponding to the beam i, for example: offset of the first transmission power of SS-PBCH-Block and CSI-RS power corresponding to beam i, and offset of the third transmission power of SS-PBCH-Block and CSI-RS power corresponding to beam i.
In the above embodiment, since the transmission power is configured for each SS-PBCH-Block, and the SS-PBCH-Block corresponds to a beam, SS-PBCH-Block power configuration based on a specific beam (beam specific) may be implemented, so as to support configuring coverage separately for each beam, for example: as shown in fig. 3, the coverage areas of different beams are different, so that the network coverage area can be flexibly configured.
Alternatively, the third transmission power of each SS-PBCH-Block may be a transmission power determined according to the second transmission power and an offset of the SS-PBCH-Block third transmission power from the second transmission power.
As an alternative embodiment, the method further comprises:
determining a second path loss value according to the high-layer filtered second reference signal receiving power and the second reference signal transmitting power, wherein the second reference signal transmitting power corresponds to at least one of the following: the offset of the third transmission power of the second SS-PBCH-Block and the second transmission power, and the second transmission power;
the second SS-PBCH-Block is any one of the plurality of 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 of the plurality of SS-PBCH-blocks, the step of determining the second path loss value may be determining a corresponding second path loss value for each SS-PBCH-Block to obtain a second path loss value of each SS-PBCH-Block.
In this embodiment, the power configuration may be implemented in a case where the power configuration includes a second transmission power of SS-PBCH-blocks configured in units of cells, and an offset of a third transmission power of each SS-PBCH-Block of the plurality of SS-PBCH-blocks from the second transmission power.
The second reference signal transmission power may correspond to the second transmission power, and the third transmission power corresponding to the second SS-PBCH-Block may correspond to an offset of the second transmission power. Preferably, the second reference signal transmission power is an offset of the second transmission power added to a third transmission power of the second SS-PBCH-Block and the second transmission power. For example: and under the condition that the terminal is not configured with periodical CSI-RS reception, the second reference signal transmission power is the second transmission power plus the offset of 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: and the sum of the offset of the third transmission power of the second SS-PBCH-Block and the second transmission power, the second transmission power and the offset of the third transmission power of the second SS-PBCH-Block and the CSI-RS power. For example: under the condition that the terminal has the configured periodical CSI-RS reception, the second reference signal transmission power is as follows: and the sum of the offset of the third transmission power of the second SS-PBCH-Block and the second transmission power, the second transmission power and the offset of the third transmission power of the second SS-PBCH-Block and the CSI-RS power.
In this embodiment, the second path loss value is determined according to the second reference signal received power and the second reference signal transmission power, so that the path loss value is more accurate.
For example: because the beams and the SS-PBCH-Block are in one-to-one correspondence, the path loss of each beam can be calculated through the following formula:
referenceSignalPower(i)＝ss-PBCH-BlockPower+BeamSpecificPowerOffset(i)
PL(i)＝referenceSignalPower(i)–higher layer filtered RSRP
where i corresponds to each beam, i.e., PL (i) above may refer to the path loss of beam i;
the referenceSignalPower (i) indicates a second reference signal transmission power of the beam i, the SS-PBCH-Block power indicates a second transmission power of the SS-PBCH-Block of the cell, the BeamSpecificPowerOffset (i) indicates an offset between a third transmission power of the SS-PBCH-Block corresponding to the beam i and the second transmission power, and the higher layer filtered RSRP indicates a second reference signal reception power of the higher layer filtering.
Also for example: because the beams and the SS-PBCH-Block are in one-to-one correspondence, the path loss of each beam can be calculated through the following formula:
referenceSignalPower(i)＝ss-PBCH-BlockPower+powerControlOffsetSS(i)+BeamSpecificPowerOffset(i)
PL(i)＝referenceSignalPower(i)–higher layer filtered RSRP
the powerControlOffsetSS (i) indicates an offset between the third transmission power of SS-PBCH-Block and the CSI-RS power corresponding to the beam i.
In the above embodiment, since the second transmission power of the SS-PBCH-Block of each cell and the offset between the third transmission power of each SS-PBCH-Block and the second transmission power can be configured, SS-PBCH power configuration based on specific cell specific) +specific beam power offset (beamspecific power offset) can be implemented, so as to support individual configuration of coverage for each beam of different cells, for example: as shown in fig. 4, the coverage areas of different beams of different cells are different, so as to realize flexible configuration of network coverage.
As an alternative embodiment, the power configuration includes:
a second transmission power of SS-PBCH-Block configured in a cell unit;
power control parameters for each of the plurality of beams.
The power control parameter may be an uplink power control parameter (UL PC parameters). The power control parameter may be a power control parameter of an uplink channel of a beam or a reference signal. In addition, in the embodiment of the present invention, the beam may be an uplink beam.
In the above embodiment, since the second transmission power of the SS-PBCH-Block of each cell and the power control parameter of each beam can be configured, SS-PBCH power configuration based on the specific cell (cell specific) +uplink power control parameter (UL PC parameters) can be implemented, so that the coverage area is supported to be configured for each beam of different cells separately, and thus flexible configuration of network coverage area is implemented.
Likewise, this embodiment may also determine the path loss of the beam, for example:
and determining a third loss value according to the third reference signal receiving power and the third reference signal transmitting power of the high-layer filtering, wherein the third reference signal transmitting power corresponds to the second transmitting power, and the third reference signal receiving power corresponds to the receiving power of the SS-PBCH-Block.
For example: in the case where the third reference signal transmission power is the second transmission power, specifically, in the case where the terminal is not configured with periodic CSI-RS reception, the path loss of the beam may be calculated by the following formula:
referenceSignalPower(i)＝ss-PBCH-BlockPower
PL(i)＝referenceSignalPower–higher layer filtered RSRP+ULPCParameterOffset(i)
where i corresponds to each beam, i.e., PL (i) above may refer to the path loss of beam i;
the referenceSignalPower (i) indicates the third reference signal transmission power of the beam i, the SS-PBCH-Block power indicates the second transmission power of the SS-PBCH-Block of the cell, the higherlayer filtered RSRP indicates the third reference signal reception power of the higher layer filtering, and the ULPCParameterOffset (i) indicates the power control parameter of the beam i.
For example: in the case where the third reference signal transmission power is the 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, in the case where the terminal has configured periodic CSI-RS reception, the path loss of the beam may be calculated by the following formula:
referenceSignalPower(i)＝ss-PBCH-BlockPower+powerControlOffsetSS(i)
PL(i)＝referenceSignalPower(i)–higher layer filtered RSRP+ULPCParameterOffset(i)
the powerControlOffsetSS (i) indicates an offset between the first transmission power of the SS-PBCH-Block and the CSI-RS power corresponding to the beam i, or an offset between the third transmission power of the SS-PBCH-Block and the CSI-RS power corresponding to the beam i, which is not described herein.
In the embodiment of the invention, the network coverage area can be flexibly configured, and in addition, the path loss of each wave beam can be accurately determined. In addition, the terminal can also perform communication operation according to the path loss of each beam so as to realize that the communication operation of the terminal corresponds to the network coverage area, thereby improving the communication capability of the terminal. Wherein the communication operation includes, but is not limited to: determining the coverage of a beam, communication operations in which data transmission may use path loss, etc.
The above power configuration method provided by the embodiment of the present invention is illustrated by a plurality of embodiments in three cases:
case one:
SS-PBCH (i.e., SS-PBCH-Block) power configuration based on a specific beam (beam specific); for example: the network device configures a transmit power for each SS-PBCH through a broadcast channel.
Scheme one: example one
If the terminal does not configure periodic CSI-RS reception, the reference signal transmitting power in path loss calculation is determined by a higher layer configuration parameter: the SS/PBCH (SS-PBCH-Block Power) Block power (e.g., the first transmit power or the third transmit power of each SS-PBCH-Block) is obtained, 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 II: example two
If the terminal configures periodic CSI-RS reception, the path loss calculation is based on the CSI-RS resource, the reference signal transmission power is calculated by parameters of SS/PBCH block power configured by a higher layer, SS/PBCH block power and CSI-RS power offset (powerControlOffsetSS), and the path loss calculation mode 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 a power offset of 0dB.
