The mode of reason Uplink Shared Channel does not limit.
In the present embodiment, the first or second Transmission Time Interval can be that terminal device transmission physical uplink is shared
The time granularity of channel.For example, in 3GPP TS 36.211V15.1.0 agreements, the length of 1 radio frames is 10ms.It is one long
The radio frames that degree is 10ms are made of the subframe that 10 length are 1ms, and the length of dispatching cycle is the length of a subframe.One

For example, the first Transmission Time Interval is sTTI#1, the second Transmission Time Interval is sTTI#2, demodulation reference letter
Number be located at sTTI#2.
Step 200, according in first Transmission Time Interval when 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, determine described in
The power assignment value of first Physical Uplink Shared Channel, i.e. the first performance number；
It should be noted that in step 200, distributed according to each channel power in preset first Transmission Time Interval
The transmission power required value of each channel in priority, first Transmission Time Interval, in first Transmission Time Interval
Maximum transmission power can determine that the power assignment value of each channel in first Transmission Time Interval (wherein includes described first
The power assignment value of Physical Uplink Shared Channel)；Each channel can be with the power distribution in first Transmission Time Interval
Value is used 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

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.According to preset power distribution priority level, according in first Transmission Time Interval each channel it is specific
Attribute determines power distribution priority for each channel in first Transmission Time Interval.
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
Timeslot-based sPUSCH channels without HARQ-ACK>Timeslot-based sPUSCH channels without HARQ-ACK in P2>Nothing in P1
The PUSCH channels of HARQ-ACK>PUSCH channels without HARQ-ACK in P2.Wherein, in the uplink cells of P1 GC group connectors equipment
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.
It should also be noted that, in step 200, if the demodulated reference signal is in first Transmission Time Interval
It is interior, using the demodulated reference signal as a channel, physically with first Physical Uplink Shared Channel or described second
Power distribution priority of the power distribution priority of the shared channel of row as the demodulated reference signal, carries out power distribution.
A channel in using the demodulated reference signal as first Transmission Time Interval, with the physical uplink
Power distribution priority of the power distribution priority of shared channel as the demodulated reference signal, in conjunction with preset each channel
In power distribution priority, first Transmission Time Interval when transmission power required value of each channel, first transmission
Between be spaced in maximum transmission power, determine the power assignment value of the demodulated reference signal, i.e. the first performance number；
It should be noted that in step 200, using demodulated reference signal as one in first Transmission Time Interval
A channel, in conjunction with the transmission power of each channel in preset channel power distribution priority, first Transmission Time Interval
Maximum transmission power, determines each channel in first Transmission Time Interval in required value, first 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 first Transmission Time Interval, in conjunction with
It is the transmission power required value of each channel in preset each channel power distribution priority, first Transmission Time Interval, described
Maximum transmission power in first 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 first 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 200, the value of the power demand of the demodulated reference signal is：First physics
The power demand of Uplink Shared Channel.
According to an embodiment of the invention, it is ensured that the transmission of each up channel to be sent in the first Transmission Time Interval
Power meets preset power distribution priority level rule.
For example, according to the present embodiment, the power distribution priority level comprising DMRS is as follows in step 200：
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#1, 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#1, 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#1, 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#1 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).
Step 300, distributed according to each channel power priority, in second Transmission Time Interval each channel transmission
Maximum transmission power, determines second Physical Uplink Shared Channel in power demand, second Transmission Time Interval
Power assignment value, i.e. the second performance number；
It should be noted that in step 300, distributed according to each channel power in second Transmission Time Interval preferential
Grade, the transmission power required value of each channel in first Transmission Time Interval, the maximum in second Transmission Time Interval
Transmission power can determine that the power assignment value of each channel in second Transmission Time Interval (wherein includes second physics
The power assignment value of Uplink Shared Channel)；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.According to preset power distribution priority level, such as specified in 3GPP TS 36.213V15.1.0 agreements
Power distribution priority level, according to the specific object of each channel in second Transmission Time Interval, when being transmitted for described second
Between be spaced in each channel determine power distribution priority.
The transmission power required value of each channel is preset in second 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 second Physical Uplink Shared Channel is determined for the power control command of the second Physical Uplink Shared Channel
Required value is P2’.For another example in sTTI#2, in addition to second Physical Uplink Shared Channel, terminal device will also send other
X channel, wherein X >=0.Terminal device determines the shared letter of second 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, second Transmission Time Interval
Maximum transmission power in the transmission power required value of channel, second Transmission Time Interval, determines described second physically
The method of the power assignment value of the shared channel of row, specifically includes：Maximum of the terminal device in second Transmission Time Interval
Transmission power preferentially meets the high channel of power distribution priority, and dump power cannot meet the low channel of power distribution priority
When, then equal proportion reduces the low channel power of the power distribution priority, keeps the dump power excellent by the power distribution
The low channel of first grade is shared.
For example, the sum of transmission power required value of each channel in the sTTI#2 is more than terminal device in sTTI#2 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#2
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#2, 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#2, 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#2 maximum transmission power.
It should also be noted that, in step 300, if the demodulated reference signal is in second Transmission Time Interval
It is interior, using the demodulated reference signal as a channel, physically with first Physical Uplink Shared Channel or described second
Power distribution priority of the power distribution priority of the shared channel of row as the demodulated reference signal, carries out power distribution.

Each channel power distribution priority in time interval, in second Transmission Time Interval each channel transmission power requirement
Maximum transmission power, determines the power assignment value of the demodulated reference signal, i.e., second in value, second Transmission Time Interval
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
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

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, the power of the power distribution priority level such as step 200 comprising DMRS in step 300
It distributes listed by priority level.
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).
