Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
Embodiments of the present invention are described below with reference to the accompanying drawings. The power configuration method, the terminal and the network equipment provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, an Evolved Long Term Evolution (LTE) system, a subsequent Evolution communication system, or the like.
Referring to fig. 1, fig. 1 is a structural diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a terminal 11 and a network device 12, where the terminal 11 may be a User Equipment (UE) or other terminal-side devices, for example: it should be noted that, in the embodiment of the present invention, a specific type of the terminal 11 is not limited. The network device 12 may be a 4G base station, or a 5G base station, or a later-version base station, or a base station in another communication system, or referred to as a node B, an evolved node B, or a Transmission Reception Point (TRP), or an Access Point (AP), or another vocabulary in the field, and the network device is not limited to a specific technical vocabulary as long as the same technical effect is achieved. In addition, the network device 12 may be a Master Node (MN) or a Secondary Node (SN). It should be noted that, in the embodiment of the present invention, only the 5G base station is taken as an example, but the specific type of the network device is not limited.
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, and as shown in fig. 2, the method includes the following steps:
step 201, receiving a power configuration, where the power configuration includes:
a first transmit power of each of a plurality of SS-PBCH-blocks; or
A second transmission power of the SS-PBCH-Block configured in units of a cell, and an offset of a third transmission power of each of the plurality of SS-PBCH-blocks from the second transmission power.
Step 201 may be receiving the power configuration sent by the network device, for example: and receiving the power configuration configured by the network equipment through a broadcast channel or receiving the power configuration configured by the network equipment at a higher layer. In addition, the plurality of SS-PBCH-blocks may be all or part of SS-PBCH-blocks that may 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 transmit power of each of the plurality of SS-PBCH-blocks may be a transmit power configured in units of SS-PBCH-Block, 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 the transmission power of the SS-PBCH-Block configured for each cell, that is, the transmission power of the cell-level SS-PBCH-Block is configured, and one SS-PBCH-Block is configured for one cell. For example: a certain network device has 3 cells, and the 3 cells may be respectively configured with 3 SS-PBCH-blocks of second transmission power.
For the offset between the third transmit power and the second transmit power of each SS-PBCH-Block in the plurality of SS-PBCH-blocks, the third transmit power of each SS-PBCH-Block in the plurality of SS-PBCH-blocks may be configured with the third transmit power in units of SS-PBCH-blocks, and the offset of the second transmit power may be configured with different offsets for different SS-PBCH-blocks, or of course, some SS-PBCH-blocks may be configured with the same offset and other SS-PBCH-blocks may be configured with different offsets.
The third transmit power of the SS-PBCH-Block may be configured, based on the second transmit power of the SS-PBCH-Block configured in units of cells, with a third transmit power for each SS-PBCH-Block in the cell.
Note that, the above "or" indicates that the above power configuration includes: a first transmit power of each of a plurality of SS-PBCH-blocks; in another case, the power configuration includes: a second transmission power of the SS-PBCH-Block configured in units of a cell, and an offset of a third transmission power of each of the plurality of SS-PBCH-blocks from the second transmission power.
In the embodiment of the invention, the independent configuration of the sending power for each SS-PBCH-Block can be supported, and/or the independent configuration of the offset of the second sending 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 optional implementation, the method further comprises:
determining a first path loss value according to a first reference signal received power (high layer filtered RSRP) of a high layer filter and a first reference signal transmission power, wherein the first reference signal transmission power corresponds to a first transmission power of a first SS-PBCH-Block or a third transmission power of the first SS-PBCH-Block, and the first reference signal reception power corresponds to a reception power of the first SS-PBCH-Block;
the first SS-PBCH-Block is any one of the plurality of SS-PBCH-blocks.
Since the first SS-PBCH-Block is any one of the plurality of SS-PBCH-blocks, the step of determining the first path loss value may be determining a corresponding first path loss value for each SS-PBCH-Block to obtain the first path loss value of each SS-PBCH-Block.
It should be noted that, in the embodiment of the present invention, beams and SS-PBCH-blocks are in a one-to-one correspondence relationship, 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-Block 3. Specifically, each beam may correspond to one SS-PBCH-Block identifier. Therefore, in this embodiment of the present invention, the transmission power of each SS-PBCH-Block may also be referred to as transmission power of each beam, that is, transmission power of a beam level, and an offset between the third transmission power and the second transmission power of each SS-PBCH-Block may also be referred to as an offset between 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 referred to as an SSB or an 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 that is provided by the transmitting end to the receiving end for channel estimation or channel sounding.
The first reference signal received power may be pre-configured to correspond to the received power of the SS-PBCH-Block. 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 configured in advance 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: and under the condition that the terminal is not configured with 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 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 first reference signal transmission power is: the first transmit power of the first SS-PBCH-Block plus an offset between the first transmit power of the first SS-PBCH-Block and the CSI-RS power, and the third transmit power of the first SS-PBCH-Block plus an offset between the third transmit power of the first SS-PBCH-Block and the CSI-RS power. The CSI-RS power may be a CSI-RS transmission power.
It should be noted that, in the case that 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 offset between the first transmit power or the third transmit power of the first SS-PBCH-Block and the CSI-RS power is 0 dB.
Preferably, when the terminal has configured periodic CSI-RS reception, the first reference signal transmission power may be: the first transmit power or the third transmit power of the first SS-PBCH-Block plus an offset of the first transmit power or the third transmit power of the first SS-PBCH-Block from 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 high-level 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 high-level 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 by 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 referrence signaling power (i) indicates a first reference signal transmission power of a beam i, the SS-PBCH-BlockPower (i) indicates a first transmission power of an SS-PBCH-Block corresponding to the beam i or a third transmission power of the SS-PBCH-Block corresponding to the beam i, and the higher layer filtered RSRP indicates a first reference signal reception power of a higher layer filter.
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 by the following formula:
referenceSignalPower(i)＝ss-PBCH-BlockPower(i)+powerControlOffsetSS(i)
PL(i)＝referenceSignalPower(i)–higher layer filtered RSRP
the powerControlOffsetSS (i) represents a power offset corresponding to the beam i, and includes: and the offset between the first transmission power of the SS-PBCH-Block corresponding to the beam i and the CSI-RS power, and the offset between the third transmission power of the SS-PBCH-Block corresponding to the beam i and the CSI-RS power.
In the above embodiment, since the transmit power is configured for each SS-PBCH-Block, and the SS-PBCH-Block corresponds to a beam, the SS-PBCH-Block power configuration based on a specific beam (beam specific) can be implemented, so as to support configuring the coverage range for each beam separately, for example: as shown in fig. 3, the coverage areas of different beams are different, thereby realizing flexible configuration of the network coverage area.
Optionally, the third transmit power of each SS-PBCH-Block may be a 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 method further includes:
determining a second path loss value according to a second reference signal receiving power and a second reference signal transmitting power of the high-layer filtering, wherein the second reference signal transmitting power corresponds to at least one of the following: an offset between a third transmission power of a 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 one of the plurality of SS-PBCH-blocks, the step of determining the second impairment value may be to determine a corresponding second impairment value for each SS-PBCH-Block to obtain the second impairment value for each SS-PBCH-Block.
This embodiment can be implemented when the power configuration includes a second transmission power of the SS-PBCH-Block configured in a cell unit and an offset between a third transmission power of each of the plurality of SS-PBCH-blocks and the second transmission power.
The second reference signal transmission power may correspond to the second transmission power, and may correspond to an offset between a 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 a third transmission power of the second SS-PBCH-Block and the second transmission power. For example: and when the terminal does not configure periodic CSI-RS reception, the second reference signal transmission power is the second transmission power plus an offset between the second transmission power and a third transmission power of the second SS-PBCH-Block.
Of course, in this embodiment of the present invention, the transmission power of the second reference signal may also be: a sum of an offset of the third transmit power of the second SS-PBCH-Block from the second transmit power, and an offset of the third transmit power of the second SS-PBCH-Block from the CSI-RS power. For example: when the terminal has configured periodic CSI-RS reception, the transmission power of the second reference signal is: a sum of an offset of the third transmit power of the second SS-PBCH-Block from the second transmit power, and an offset of the third transmit power of the second SS-PBCH-Block from 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 by 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 referrence signaling power (i) indicates a second reference signal transmission power of a beam i, the SS-PBCH-BlockPower indicates a second transmission power of an SS-PBCH-Block of a cell, the beamspecificpowermeffefset (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 a higher layer filter.
Another example is: because the beams and the SS-PBCH-Block are in 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) indicates an offset between the CSI-RS power and the third transmission power of the SS-PBCH-Block corresponding to the beam i.
In the foregoing embodiment, since the second transmission power of the SS-PBCH-Block of each cell and the offset between the third transmission power and the second transmission power of each SS-PBCH-Block can be configured, the SS-PBCH power configuration based on a specific cell (cell specific) + specific beam power offset (beam specific power offset) can be implemented, so as to support separate configuration of a coverage range for each beam of different cells, for example: as shown in fig. 4, the coverage areas of different beams of different cells are different, thereby achieving flexible network coverage configuration.
As an optional implementation, the power configuration includes:
a second transmission power of the SS-PBCH-Block configured by taking a cell as a unit;
a power control parameter for each of the plurality of beams.
The power control parameter may be uplink power control parameters (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 foregoing embodiment, since the second transmit power of the SS-PBCH-Block of each cell and the power control parameter of each beam may be configured, the SS-PBCH power configuration based on specific cell (cell specific) + uplink power control parameter (UL PC parameters) may be implemented, so as to support separate configuration of a coverage for each beam of different cells, and further implement flexible configuration of a network coverage.
Likewise, this embodiment may also determine the path loss of the beam, for example:
and determining a third path loss value according to a third reference signal received power of high-layer filtering and a third reference signal transmission power, wherein the third reference signal transmission power corresponds to the second transmission power, and the third reference signal received power corresponds to the received power of the SS-PBCH-Block.
For example: when the third reference signal transmission power is the second transmission power, specifically, when 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 referrersignalPower (i) indicates a third reference signal transmission power of a beam i, the SS-PBCH-BlockPower indicates a second transmission power of an SS-PBCH-Block of a cell, the higherlayer filtered RSRP indicates a third reference signal reception power of a higher layer filter, and the ULPCParameterOffset (i) indicates a power control parameter of the beam i.
For example: when the third reference signal transmission power is the second transmission power plus the first transmission power of the third SS-PBCH-Block or an offset between the third transmission power and the CSI-RS power, specifically, when 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 corresponding to the beam i and the CSI-RS power, or indicates an offset between the third transmission power of the SS-PBCH-Block corresponding to the beam i and the CSI-RS power, which is not described herein again.
In the embodiment of the invention, the network coverage can be flexibly configured, and in addition, the path loss of each beam can be accurately determined. In addition, the terminal can also perform communication operation according to the path loss of each beam, so that the communication operation of the terminal corresponds to the network coverage, and the communication capability of the terminal is improved. Wherein the communication operation includes, but is not limited to: determining the coverage of the beam, the communication operation that the data transmission can use the path loss, and the like.
The above power configuration method provided by the embodiment of the present invention is illustrated by a plurality of embodiments in three cases as follows:
the first condition is as follows:
SS-PBCH (i.e., SS-PBCH-Block) power configuration based on a specific beam (beam specific); for example: the network device configures transmit power for each SS-PBCH over a broadcast channel.
The first scheme is as follows: (embodiment one)
If the terminal does not configure periodic CSI-RS reception, the reference signal transmission power during path loss calculation is configured by a high layer: obtaining SS/PBCH (SS-PBCH-Block Power) Block power (for example, the first transmission power or the third transmission power of each SS-PBCH-Block), wherein the corresponding way loss calculation mode 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: (second embodiment)
If the terminal configures periodic CSI-RS receiving, the path loss calculation is based on the CSI-RS resource, the reference signal sending power is calculated by parameters SS/PBCH block power configured by a high layer and 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 CSI-RS power offset are not provided to the UE, the UE assumes a power offset of 0 dB.
Case two, SS-PBCH power configuration based on specific cell (cell specific) + specific beam power offset (beam specific offset); for example: the network device may configure ss-PBCH-Block Power for each cell through a broadcast channel, and then configure different Power offsets for different beams of each cell.
The third scheme is as follows: (third embodiment)
And if the terminal is not configured with periodical CSI-RS receiving, the reference signal sending power during the path loss calculation is acquired by the power of a high-level configuration parameter SS/PBCH block. The corresponding way of calculating the path loss is as follows:
referenceSignalPower(i)＝ss-PBCH-BlockPower+BeamSpecificPowerOffset(i)
