Attached drawing is closed to be described in further detail the embodiment of the present invention.It should be appreciated that specific embodiment described herein is only used to
It explains the present invention, is not intended to limit the present invention.
Embodiment one:
When base station is scheduled the uplink of UE, it is thus necessary to determine that several factors, the speed including running time-frequency resource, transmission
Rate, modulation coding scheme, MIMO (Multiple-Input Multiple-Output, multiple antennas) mode etc., based on the received
Quality, base station need to judge which factor subsequent scheduling needs to adjust, and such as improve modulation coding scheme, improve transmission power
Deng.But the current transmission power of UE is not known in base station, does not know whether that transmission power can be improved yet.Therefore it is deposited in LTE
In a kind of mechanism, UE sends PHR (power headroom Report, power headroom reporting (PHR)) to base station, clearly informs and works as forward pass
Defeated needs send power and the maximum difference for sending power.
When calculating PHR, there are uplink, then PHR is that the maximum power that sends subtracts the actual uplink needs
Transmission power, this PHR is known as true PHR.At least one the transmission power that actual uplink needs and following parameter phase
Close: transmit occupancy frequency domain width, transmission occupy frequency domain position, the data rate of transmission, the MCS of transmission, transmission lattice
Formula, open loop power control part, closed-loop power control part, path loss compensate part.
Uplink is not present when calculating PHR, then PHR is virtual PHR, and virtual PHR is to send power with maximum to subtract
The open loop power control part of virtual PHR, closed-loop power control part, path loss compensate part.
According to the transport-type that calculating PHR is considered, and the combined difference of transmission, PHR can divide into different
Type.For example, the PHR of Class1 is for PUSCH (Physical Uplink Shared Channel, the shared letter of physical uplink
Road) transmission, the PHR of type 2 is for PUCCH (Physical Uplink Control Channel, physical uplink link
Control channel) transmission or PUCCH+PUSCH transmission, the PHR of type 3 is for SRS (Sounding Reference
Signal, channel-sounding signal) transmission.
When UE is in PUSCH transmission phase (transmission period) i of the uplink BWP b of the carrier wave f of serving cell c
The virtual PHR calculation formula of upper transmission PUSCH, Class1 are as follows:
Wherein, i refers to the transmission phase of PUSCH, and j is the index of the open loop power control parameter sets of PUSCH transmission, qdIt is PL
The index of the configuration set of the RS used is measured,For some conditions limitation under maximum transmission power value,
αb,f,cIt (j) is the path loss factor of transmission, PLb,f,c(qd) it is path loss, fb,f,c(i, l) is the closed power control of terminal local
Adjustment amount processed, Po_PUSCH,b,f,cIt (j) is the target received power of PUSCH transmission comprising cell-level target received power and end
Hold grade target received power.
In terms of power control angle, PUSCH transmission is divided into 3 classes, and first kind PUSCH transmission is by random access request
The PUSCH transmission of (random accessrequest, RAR) uplink authorization information scheduling, also known as Msg3PUSCH are transmitted (i.e.
The transmission of third message in uplink random access procedure)；Second class PUSCH transmission is configuration authorization (configured
Grant PUSCH transmission) refers to that PUSCH transmission needs to control information (DCI, Downlink Control by physical layer descending
The transmission of uplink authorization information (UL grant) dynamic dispatching for including in Information)；Third class PUSCH transmission is base
In the PUSCH transmission of dynamic authorization (grant based transmission), it is also referred to as not necessarily to the transmission of dynamic authorization
(grant free transmission) is not needed to transmit every time and all be dispatched by uplink authorization information.
Due to not being parameter that each cell can be configured first kind PUSCH transmission, for certain cells,
The parameter of its first kind PUSCH transmission can not be got, the cell-level target of its first kind PUSCH transmission can not be also got

In the present embodiment, when object transmission only includes a kind of transmission, such as object transmission only includes the of second community
When a kind of PUSCH transmission or object transmission only include the second class PUSCH transmission of first community, then according to the object transmission
Cell-level target received power parameter determines the virtual PHR of first community.When object transmission includes at least two transmission, example
As object transmission includes the second class PUSCH transmission of first community, the third class PUSCH transmission of first community, first community
PUCCH transmission etc., then can select a kind of object transmission from this at least two object transmission, then, according to the target of selection
The cell-level target received power parameter of transmission determines the virtual PHR of first community.Wherein, from least two object transmissions
In when selecting a kind of object transmission, include, but are not limited to, the following ways: priority being set for each object transmission, according to each target
The priority of transmission therefrom selects the object transmission of highest priority.The object transmission of highest priority can not got
When cell-level target received power parameter, the cell-level target received power ginseng for the object transmission that available priority is taken second place
Number, and so on.For a better understanding, being illustrated here with three examples:
Example one, it is assumed that object transmission includes the first kind PUSCH transmission of second community, the second class of first community
The PUCCH transmission of PUSCH transmission, first community, in preset priority, the first kind PUSCH transmission of second community it is preferential
The priority of priority > first community PUCCH transmission of second class PUSCH transmission of grade > first community, then select second

Example two, it is assumed that object transmission includes the second class PUSCH transmission and third class PUSCH transmission, the second class PUSCH
The priority of transmission > third class PUSCH transmission priority, if the cell-level target that can get the second class PUSCH transmission connects
Power parameter is received, then the virtual of first community is determined according to the cell-level target received power parameter of the second class PUSCH transmission
PHR is passed if the cell-level target received power parameter of the second class PUSCH transmission can not be got according to third class PUSCH
Defeated cell-level target received power parameter determines the virtual PHR of first community.
Example three, it is assumed that object transmission includes the second class PUSCH transmission and third class PUSCH transmission, the second class PUSCH
The priority of transmission < third class PUSCH transmission priority, if the cell-level target that can get third class PUSCH transmission connects
Power parameter is received, then the virtual of first community is determined according to the cell-level target received power parameter of third class PUSCH transmission
PHR is passed if the cell-level target received power parameter of third class PUSCH transmission can not be got according to the second class PUSCH
Defeated cell-level target received power parameter determines the virtual PHR of first community.
When object transmission include PUCCH transmission when, i.e., object transmission include first community PUCCH transmission and/or second

Battle array, the precoding for transmitting terminal multiport.Code word matrix row and the layer of transmission correspond.The column of code word matrix and transmission
Antenna port correspond.
Base station scheduling UE (terminal) sends SRS and is also channel detection for measuring up channel.It is visited according to channel base station
The result of survey is that subsequent uplink determines MIMO parameter, including the number of plies, precoding etc..It base station may be different for UE configuration
SRS resource, UE sends different SRS in different SRS resources, then base station also needs to indicate SRS money for uplink
