Signal deployment terminal device sends Physical Uplink Shared Channel in certain resource.The present invention sets network equipment dispatch terminal
Preparation send the mode of Physical Uplink Shared Channel not limit.
Transmission Time Interval refers to the length of an independent decoding transmission in Radio Link.In the present embodiment, it transmits
Time interval can be the time granularity that terminal device sends Physical Uplink Shared Channel.For example, 3GPP TS
In 36.211V15.1.0 agreements, the length of 1 radio frames is 10ms.The radio frames that one length is 10ms are by 10 length

Physical Uplink Shared Channel, and the corresponding demodulated reference signal of the Physical Uplink Shared Channel is between the second transmission time
Every interior.For example, the first Transmission Time Interval is sTTI#1, and the second Transmission Time Interval is sTTI#2.
Step 200, according to each channel in preset each channel power distribution priority, first Transmission Time Interval
Maximum transmission power in transmission power required value, first Transmission Time Interval, determines the Physical Uplink Shared Channel
Power assignment value, i.e. the first performance number；
It should be noted that in step 200, when according to preset each channel power distribution priority, first transmission
Between be spaced in the transmission power required value of each channel, the maximum transmission power in first Transmission Time Interval can determine institute
The power assignment value for stating each channel in the first Transmission Time Interval (wherein includes the power distribution of the Physical Uplink Shared Channel
Value)；Each channel can be using the power assignment value as actual transmission power.
The power distribution priority level of each channel is that the communication protocol of the network equipment and terminal device is preset.Each channel
Power distribution priority level is related at least one of following factor：Whether include uplink control in the information that each channel is transmitted
The type for the ascending control information that the information that information processed, each channel are transmitted includes, each channel belong to main PUCCH groups or belong to
In auxiliary PUCCH groups.
For example, in 3GPP TS 36.213V15.1.0 agreements, power distribution priority level is as follows：
There are the sPUSCH/sPUCCH channels based on symbol of HARQ-ACK in P1>Have in P2 HARQ-ACK based on symbol
Number sPUSCH/sPUCCH channels>There are the timeslot-based PUSCH/PUCCH channels of HARQ-ACK in P1>There is HARQ- in P2
The timeslot-based PUSCH/PUCCH channels of ACK>There are the PUSCH/PUCCH channels based on subframe of HARQ-ACK in P1>In P2
There are the PUSCH/PUCCH channels based on subframe of HARQ-ACK>In P1 without HARQ-ACK but have DMRS based on symbol
SPUSCH channels>Without HARQ-ACK but there are the sPUSCH channels based on symbol of DMRS in P2>In P1 without HARQ-ACK also without
The sPUSCH channels based on symbol of DMRS>In P2 without HARQ-ACK also sPUSCH channels based on symbol without DMRS>In P1

Main plot in main PUCCH groups (primary PUCCH group), auxiliary PUCCH groups in the uplink cells of P2 GC group connector equipment
Main plot in (secondary PUCCH group).
The transmission power required value of each channel is preset in first Transmission Time Interval, and terminal device is according to network
The power control command that equipment is sent, determines the transmission power required value.Such as：Terminal device is sent according to the network equipment
The transmission power of first Physical Uplink Shared Channel is determined for the power control command of the first Physical Uplink Shared Channel
Required value is P1’.For another example in sTTI#1, in addition to first Physical Uplink Shared Channel, terminal device will also send other
X channel, wherein X >=0.Terminal device determines the shared letter of first physical uplink according to the power control command of the network equipment
Road and the respective transmission power required value of the X channel.
It should be noted that according to each in preset each channel power distribution priority, first Transmission Time Interval
Maximum transmission power in the transmission power required value of channel, first Transmission Time Interval determines that the physical uplink is total
The method for enjoying the power assignment value of channel, specifically includes：Maximum transmission of the terminal device in first Transmission Time Interval
Power preferentially meets the high channel of power distribution priority, when dump power cannot meet power distribution priority low channel,
Then equal proportion reduces the low channel power of the power distribution priority, makes the dump power by the power distribution priority
Low channel is shared.
For example, the sum of transmission power required value of each channel in the sTTI#1 is more than terminal device in sTTI#1 most
When big transmission power, terminal device determines each channel according to the power distribution priority level of each channel to be transmitted in sTTI#1
Power assignment value, as actual transmission power.
Assuming that the channel of power distribution priority level A has X0, the channel of power distribution priority level A-1 has X1, work(
The sum of transmission power required value of all channels that rate distributes priority level A and specific power distribution priority level A high is less than etc.
In terminal device in the maximum transmission power of sTTI#1, power distribution priority level A-1 and specific power distribute priority level A-1
The sum of high transmission power required value of all channels is more than terminal device in the maximum transmission power of sTTI#1, then terminal device
Determine according to the actual transmission power of each channel of power distribution priority level A and specific power distribution priority level A high this
The transmission power required value of a little channels, determines that the actual transmission power of each channel of power distribution priority level A-1 sends for it
W times of power demand.The practical transmission of power distribution priority level A-2 and the lower each channel of power distribution priority level
Power is 0.Wherein 0≤W≤1 meets all of power distribution priority level A-1 and specific power distribution priority level A-1 high
The sum of actual transmission power of channel no more than terminal device sTTI#1 maximum transmission power.
Step 300, using the demodulated reference signal as second Transmission Time Interval in a channel, with described
Power distribution priority of the power distribution priority of Physical Uplink Shared Channel as the demodulated reference signal, in conjunction with default
Each channel power distribution priority, the transmission power required value of each channel in second Transmission Time Interval, described the
Maximum transmission power, determines the power assignment value of the demodulated reference signal, i.e. the second performance number in two Transmission Time Intervals；
It should be noted that in step 300, using demodulated reference signal as one in second Transmission Time Interval
A channel, in conjunction with the transmission power of each channel in preset channel power distribution priority, second Transmission Time Interval
Maximum transmission power, determines each channel in second Transmission Time Interval in required value, second Transmission Time Interval
Power assignment value (power assignment value for wherein including the demodulated reference signal), each channel can be made with the power assignment value
For actual transmission power.
It should be noted that using demodulated reference signal as a channel in second Transmission Time Interval, in conjunction with
It is the transmission power required value of each channel in preset each channel power distribution priority, second Transmission Time Interval, described
Maximum transmission power in second Transmission Time Interval, the method for determining the power assignment value of the demodulated reference signal, specifically
Including：It is high that maximum transmission power of the terminal device in second Transmission Time Interval preferentially meets power distribution priority
Channel, when dump power cannot meet power distribution priority low channel, then equal proportion reduces the power distribution priority
Low channel power makes the dump power be shared by the low channel of the power distribution priority.
Preferably, in step 300, the value of the power demand of the demodulated reference signal is：The physical uplink
The power demand or power assignment value of shared channel.
According to an embodiment of the invention, it is ensured that the transmission of each up channel to be sent in the second Transmission Time Interval
Power meets preset power distribution priority level rule.
For example, according to the present embodiment, power distribution priority level is as follows in step 300：
Have in the sPUSCH/sPUCCH channels=P1 based on symbol for having HARQ-ACK in P1 HARQ-ACK based on symbol
SPUSCH channels DMRS>There is HARQ- in the sPUSCH/sPUCCH channels=P2 based on symbol for having HARQ-ACK in P2
The DMRS of the sPUSCH channels based on symbol of ACK>There are the timeslot-based PUSCH/PUCCH channels of HARQ-ACK in P1>P2
Inside there are the timeslot-based PUSCH/PUCCH channels of HARQ-ACK>There is the PUSCH/PUCCH based on subframe of HARQ-ACK in P1
Channel>There are the PUSCH/PUCCH channels based on subframe of HARQ-ACK in P2>In P1 without HARQ-ACK but have DMRS based on
The sPUSCH channels of symbol>Without HARQ-ACK but there are the sPUSCH channels based on symbol of DMRS in P2>Without HARQ-ACK in P1
Also in sPUSCH channels=P1 based on symbol without DMRS without HARQ-ACK also sPUSCH channels based on symbol without DMRS
DMRS>In P2 without HARQ-ACK also in sPUSCH channels=P2 based on symbol without DMRS without HARQ-ACK also without DMRS's
The DMRS of sPUSCH channels based on symbol>Timeslot-based sPUSCH channels without HARQ-ACK in P1>Without HARQ- in P2
The timeslot-based sPUSCH channels of ACK>PUSCH channels without HARQ-ACK in P1>PUSCH letters without HARQ-ACK in P2
Road.Wherein, the main plot in the uplink cells of P1 GC group connectors equipment in main PUCCH groups (primary PUCCH group), P2
Main plot in the uplink cells of GC group connector equipment in auxiliary PUCCH groups (secondary PUCCH group).
For example, in sTTI#2, in addition to the corresponding DMRS of Physical Uplink Shared Channel, terminal device may also need to send
Other Y channel, terminal device determine the respective transmission power of Y channel according to the power control command of the network equipment first
Required value, and using the power demand of Physical Uplink Shared Channel or power assignment value as corresponding with Physical Uplink Shared Channel
DMRS power demand.
If in sTTI#2, the power demand and other channels of DMRS corresponding with the Physical Uplink Shared Channel
The sum of power demand be more than terminal device in the maximum transmission power of sTTI#2, terminal device sets demodulated reference signal work(
Rate distributes priority, and the demodulated reference signal is determined in conjunction with the power distribution priority level of other preset Y channel channel
Power assignment value.
If there is Y1The power distribution that the power distribution priority level of a channel is more than the Physical Uplink Shared Channel is excellent
First grade has Y2The power distribution priority level of a channel is less than the power distribution priority of the Physical Uplink Shared Channel, eventually
STTI#2 maximums transmission power is preferentially distributed to the Y by end equipment successively1The corresponding DMRS of a channel, Physical Uplink Shared Channel
With the Y2A channel can ensure the higher Y of power distribution priority successively1A channel, Physical Uplink Shared Channel and power distribution
The lower Y of priority2The performance of a channel meets system efficiency of transmission and requires (wherein Y, Y1、Y2It is >=0 integer).
It should be noted that in abovementioned steps 200~300, terminal device determines the hair of Physical Uplink Shared Channel
It is the first power P to send power1, the power assignment value of the corresponding demodulated reference signal of Physical Uplink Shared Channel is the second power P2。
Information in the Physical Uplink Shared Channel that terminal device is sent may use high order modulation exponent number, such as 16QAM, 64QAM etc..
If the transmission power of Physical Uplink Shared Channel is different with the transmission power of corresponding DMRS or difference is excessive, net
The channel status that network equipment is estimated according to DMRS is used to be likely to occur judgement when demodulating the information in Physical Uplink Shared Channel wrong
Accidentally.
Step 400, according to the first performance number P1With the second performance number P2Determine demodulation ginseng in second Transmission Time Interval
The actual transmission power for examining signal, specifically includes following steps：
If the difference of step 401, first performance number and second performance number is in predetermined threshold value or described
Second performance number is more than or equal to first performance number, then within the scope of first performance number ± predetermined threshold value delta
It is worth the actual transmission power as the demodulated reference signal.
For example, if P2＞ P1, then terminal device [P1- delta, P1+ delta] in a performance number send described in
Demodulated reference signal can ensure that the network equipment correctly demodulates Physical Uplink Shared Channel to a certain extent.
For another example if P2＜ P1And P1-P2＜ delta, terminal device [P1- delta, P1+ delta] in a work(
Rate value sends the demodulated reference signal, can still ensure that the network equipment correctly demodulates the shared letter of physical uplink to a certain extent
Road.
If the difference of step 402, first performance number and second performance number is outside predetermined threshold value and second
Performance number is less than first performance number, and the actual transmission power of the demodulated reference signal is 0.
For example, if P2＜ P1And P1-P2＞ delta, then terminal device abandon the demodulated reference signal.
It should be noted that in the power assignment value P of demodulated reference signal2Less than the transmission work(of Physical Uplink Shared Channel
Rate P1, and when difference is more than preset thresholding, channel status that the network equipment estimate according to demodulated reference signal is used to demodulate
It is likely to occur mistake in judgment when information in the Physical Uplink Shared Channel, at this point, the network equipment is difficult to correctly demodulate physics
Uplink Shared Channel.In this case, terminal device sends having little significance for DMRS, abandons the hair that terminal device can be improved in DMRS
Send power efficiency.
As one embodiment, the predetermined threshold value can also be set as 0.At this point, if the power of demodulated reference signal point
With value (i.e. the second performance number P2) it is less than power assignment value (i.e. the first performance number P of the Physical Uplink Shared Channel1), terminal
Equipment abandons the demodulated reference signal.
It should be noted that if demodulated reference signal power assignment value P2Less than the hair of Physical Uplink Shared Channel
Send power P1In the case of, the network equipment is difficult to correctly demodulate Physical Uplink Shared Channel, but terminal device is passed described second
It needs available maximum transmission power to distribute to other higher Y of priority in defeated time interval again1A channel.Such case
Under, terminal device sends having little significance for DMRS, abandons the transmission power efficiency that terminal device can be improved in DMRS.
In step 401, it is preferable that the value within the scope of first performance number ± predetermined threshold value is joined as the demodulation
In the step of examining the actual transmission power of signal, further include：If second performance number is more than or equal to first work(
Rate value, then using first performance number as the actual transmission power of the demodulated reference signal.
For example, if P2＞ P1Then the first power P of terminal device1The demodulated reference signal is sent, it can be to a certain degree
The upper guarantee network equipment correctly demodulates Physical Uplink Shared Channel.
In step 401, it is preferable that the value within the scope of first performance number ± predetermined threshold value is joined as the demodulation
In the step of examining the actual transmission power of signal, further include：If second performance number is less than first performance number,
Then using second performance number as the actual transmission power of the demodulated reference signal.
For example, if P2＜ P1And P1-P2≤ delta, then terminal device P2The demodulated reference signal is sent, it still can be
Ensure that the network equipment correctly demodulates Physical Uplink Shared Channel to a certain extent.
