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 without limitation.
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 agreement, the length of 1 radio frames is 10ms.The radio frames that one length is 10ms are by 10 length

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 demand, 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 transmissions power demand 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
Whether power distribution priority level is related at least one of following factor: including uplink control in the information that each channel is transmitted
The type for the ascending control information for including in the information that information processed, each channel are transmitted, each channel belong to main PUCCH group or belong to
In auxiliary PUCCH group.
For example, in 3GPP TS 36.213V15.1.0 agreement, power distribution priority level is as follows:
Have in the sPUSCH/sPUCCH channel > P2 based on symbol for having HARQ-ACK in P1 HARQ-ACK based on symbol
Number sPUSCH/sPUCCH channel > P1 in have in timeslot-based PUSCH/PUCCH channel > P2 of HARQ-ACK and have HARQ-
Have in PUSCH/PUCCH channel > P2 based on subframe of HARQ-ACK in timeslot-based PUSCH/PUCCH channel > P1 of ACK
Have in PUSCH/PUCCH channel > P1 based on subframe of HARQ-ACK without HARQ-ACK but have DMRS based on symbol
In sPUSCH channel > P2 without HARQ-ACK but have in sPUSCH channel > P1 based on symbol of DMRS without HARQ-ACK also without
In sPUSCH channel > P2 based on symbol of DMRS without HARQ-ACK also in sPUSCH channel > P1 based on symbol without DMRS

PUSCH channel without HARQ-ACK in PUSCH channel > P2 of HARQ-ACK.Wherein, in the uplink cells of P1 GC group connector equipment
Main plot in main PUCCH group (primary PUCCH group), auxiliary PUCCH group in the uplink cells of P2 GC group connector equipment
Main plot in (secondary PUCCH group).
The transmission power demand 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 demand.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 addition to first Physical Uplink Shared Channel, terminal device will also send other in sTTI#1
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 demand of the X channel.
It should be noted that according to each in preset each channel power distribution priority, first Transmission Time Interval
Channel send power demand, maximum in first Transmission Time Interval sends power, determine 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 is not able to satisfy the low channel of power distribution priority,
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 transmissions power demand of each channel in the sTTI#1 greater 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, function
The sum of transmission power demand of all channels that rate distributes priority level A and specific power distribution priority level A high is less than etc.
Power is sent in the maximum of sTTI#1 in terminal device, power distribution priority level A-1 and specific power distribute priority level A-1
The sum of transmission power demand of high all channels is greater than terminal device and sends power in the maximum of sTTI#1, then terminal device
Determine power distribution priority level A and specific power distribution priority level A high each channel actual transmission power according to this
The transmission power demand 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 sends power in the maximum of sTTI#1 no more than terminal device.
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 demand of each channel in second Transmission Time Interval, described the
It is maximum in two Transmission Time Intervals to send power, determine the power assignment value of the demodulated reference signal, i.e. the second performance number；
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
It is maximum in required value, second Transmission Time Interval to send power, determine each channel in second Transmission Time Interval
Power assignment value (wherein including the power assignment value of 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 demand 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
It include: that maximum in second Transmission Time Interval of terminal device sends power preferentially to meet power distribution priority high
Channel, when dump power is not able to satisfy the low channel of power distribution priority, then equal proportion reduces the power distribution priority
Low channel power shares the dump power by the low channel of the power distribution priority.
Preferably, in step 300, the value of the power demand of the demodulated reference signal are as follows: the physical uplink
The power demand or power assignment value of shared channel.
According to an embodiment of the invention, can guarantee 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, power distribution priority level is as follows in step 300 according to the present embodiment:
Have in the sPUSCH/sPUCCH channel=P1 based on symbol for having HARQ-ACK in P1 HARQ-ACK based on symbol
SPUSCH channel DMRS > P2 in have in sPUSCH/sPUCCH channel=P2 based on symbol of HARQ-ACK and have HARQ-
There is timeslot-based PUSCH/PUCCH channel > P2 of HARQ-ACK in DMRS > P1 of the sPUSCH channel based on symbol of ACK
There is the PUSCH/PUCCH based on subframe of HARQ-ACK in the timeslot-based PUSCH/PUCCH channel > P1 for inside having HARQ-ACK
Have in channel > P2 in PUSCH/PUCCH channel > P1 based on subframe of HARQ-ACK without HARQ-ACK but have DMRS based on
Without HARQ-ACK but have in sPUSCH channel > P1 based on symbol of DMRS without HARQ-ACK in sPUSCH channel > P2 of symbol
Also in sPUSCH channel=P1 based on symbol without DMRS without HARQ-ACK the also sPUSCH channel based on symbol without DMRS
DMRS > P2 in without HARQ-ACK also in sPUSCH channel=P2 based on symbol without DMRS without HARQ-ACK also without DMRS's
Without HARQ- in timeslot-based sPUSCH channel > P2 in DMRS > P1 of sPUSCH channel based on symbol without HARQ-ACK
PUSCH letter in timeslot-based sPUSCH channel > P1 of ACK in PUSCH channel > P2 without HARQ-ACK without HARQ-ACK
Road.Wherein, the main plot in the uplink cells of P1 GC group connector equipment in main PUCCH group (primary PUCCH group), P2
Main plot in the uplink cells of GC group connector equipment in auxiliary PUCCH group (secondary PUCCH group).
For example, in addition to the corresponding DMRS of Physical Uplink Shared Channel, terminal device may also need to send in sTTI#2
Other Y channel, terminal device determine the respective transmission power of the 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 greater than terminal device and send power in the maximum of sTTI#2, terminal device sets demodulated reference signal function
Rate distributes priority, determines the demodulated reference signal 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 greater 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 maximum transmission power is successively preferentially distributed to the Y by end equipment1The corresponding DMRS of a channel, Physical Uplink Shared Channel
With the Y2A channel can successively guarantee the higher Y of power distribution priority1A 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 terminal device determines the hair of Physical Uplink Shared Channel in abovementioned steps 200~300
Sending power is the first power P1, the power assignment value of the corresponding demodulated reference signal of Physical Uplink Shared Channel is the second power P2。
The information in Physical Uplink Shared Channel that terminal device is sent may use high order modulation order, such as 16QAM, 64QAM etc..
If the transmission power difference or difference for sending power and corresponding DMRS of Physical Uplink Shared Channel are 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 of signal is examined, specifically includes the 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 guarantee that a certain extent the network equipment correctly demodulates Physical Uplink Shared Channel.
For another example if P2< P1And P1-P2< delta, terminal device [P1- delta, P1+ delta] in a function
Rate value sends the demodulated reference signal, can still guarantee 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 abandons the demodulated reference signal.
It should be noted that in the power assignment value P of demodulated reference signal2Less than the transmission function of Physical Uplink Shared Channel
Rate P1, and when difference is greater 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, and abandoning DMRS can be improved the hair of terminal device
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 where, the network equipment is difficult to correctly demodulate Physical Uplink Shared Channel, but terminal device is passed described second
It needs the available maximum power distribution that sends to give priority other higher Y in defeated time interval again1A channel.Such case
Under, terminal device sends having little significance for DMRS, and abandoning DMRS can be improved the transmission power efficiency of terminal device.
In step 401, it is preferable that the value within the scope of first performance number ± predetermined threshold value is joined as the demodulation
It in the step of examining the actual transmission power of signal, further includes: if second performance number is more than or equal to first function
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
Guarantee that the network equipment correctly demodulates Physical Uplink Shared Channel to a certain extent.

Power assignment value, i.e. the first performance number；
Step 500 is believed using the value within the scope of first performance number ± predetermined threshold value delta as the demodulation reference
Number power assignment value, i.e. the second performance number；
For example, directly determining the function of the demodulated reference signal according to the power assignment value of the Physical Uplink Shared Channel
Rate apportioning cost, i.e. the second performance number=first performance number.
Step 600, using second performance number as the actual transmission power of the demodulated reference signal.
Further, in any one embodiment shown in Fig. 1~2, using first power or the second performance number as
The actual transmission power of the demodulated reference signal can also further include following steps:
The actual transmission power of other channels in step 700, the second time period in addition to the demodulated reference signal
