Specific embodiment
It is right hereinafter, referring to the drawings and the embodiments, for the objects, technical solutions and advantages of the application are more clearly understood
The application is described in further detail.
In order to realize the purpose of the application, present applicant proposes a kind of methods of uplink power control, as shown in Fig. 2, should
Method the following steps are included:
Step 301: determining the timing of the ascending physical signal control channel of power control command and the application power control command
Relationship；
Step 302: according to the timing relationship of determining power control command and ascending physical signal control channel, according to power control
System order adjusts the transimission power of the ascending physical signal control channel.
At this point, by DCI scheduling PDSCH and transmit the PDSCH generate HARQ-ACK PUCCH timing relationship by
Information dynamic instruction in DCI.
Below by several preferred embodiments, technical scheme is further elaborated.
Embodiment one
The present embodiment describes the power control command of UE-group and carries out power control using the power control command
The timing relationship of uplink PUCCH transmission, power control command here refer to the common power control of UE group (UE-group)
It orders (for example, power control command that the DCI format 3/3A of LTE is transmitted), a DCI can provide for the PUCCH of multiple UE
Power control command.Here PUCCH can be used to transmit the UCI etc. of HARQ-ACK, CSI and SR.
At this point, in PDCCH of the timing relationship between PDSCH and the HARQ-ACK generated by the PDSCH by dispatching PDSCH
DCI instruction with high-level signaling configure combine determination.For example, base station configures 4 values to UE by high-level signaling, it is respectively as follows:
{ k0, k1, k2, k3 } includes the timing that 2 bits are used to refer to PDSCH between the HARQ-ACK that is generated by the PDSCH in DCI
Relationship is to gather the index of an element in { k0, k1, k2, k3 }, and PDSCH transmits in time slot n-ki, HARQ-ACK when
It is transmitted in gap n, as shown in table 5.For different UE, independent timing relationship set is respectively configured by independent high-level signaling.
At this point, by dispatch PDSCH PDCCH in DCI in include TPC command be also determined according to the timing relationship, for example,
PDSCH is transmitted in time slot n-ki, and the HARQ-ACK that PDSCH is generated is transmitted in time slot n, then scheduling is transmitted in time slot n-ki
TPC command in the PDCCH of PDSCH is applied to the power control in the PUCCH of time slot n transmission HARQ-ACK.This is by dispatching
The method that the TPC that DCI in the PDCCH of PDSCH includes carries out power control, the power control command is just for a UE.
Table 5
There are also the transmission method of another power power control command, a DCI transmits at least one power control life
It enables, each power control command is directed to a UE, referred to as UE-group power control command, which is at least one UE
's.At this point, due in PDCCH of the timing relationship between PDSCH and the HARQ-ACK generated by PDSCH by dispatching PDSCH
DCI dynamic instruction is no longer determining timing relationship, at this point, the DCI of transmission UE-group power control command and application
Timing relationship between the PUCCH of UE-group power control command adjustment power is not present, it is therefore desirable to determine that one is determined
When relationship, thus according to the timing relationship application UE-group power control command adjustment PUCCH power.
It is described below in this case, how UE determines UE-group power control command and apply UE-group power
Control command adjusts the timing relationship between the PUCCH of power.UE can (explicit signaling includes system letter by explicit signaling
Breath, high-level signaling, Medium Access Layer signaling or physical layer signaling etc.), implicit signaling and the preset method of agreement determine
Timing relationship between UE-group public power control command and the PUCCH transmission for applying these power control commands,
That is UE-group public power control command time slot n-k transmit, using the power control command PUCCH when
Gap n transmission determines that timing relationship is exactly to determine k value.The public power control life of several determining UE-group is detailed below
The method of timing relationship between the PUCCH transmission of the adjustment power of these power control commands of order and application.
Method one:
The explicit signaling (for example, system information, high-level signaling) that UE is sent by receiving base station, obtains UE-group power
Timing relationship between the PUCCH transmission of these power control commands of control command and application, that is to say, that UE-group power
Control command is transmitted in time slot n-k, is transmitted using the PUCCH of these power control commands adjustment power in time slot n, UE is by connecing
It receives the explicit signaling (for example, system information, high-level signaling) that base station is sent and obtains k value, k is an integer more than or equal to 0.When
When configuring k value by high-level signaling, it can be configured, can also be matched by the peculiar high-level signaling of UE by public high-level signaling
It sets.For UE different in a group, k value can be identical, can make in the tdd case, more easily to transmit in this way,
As shown in figure 4, otherwise, if k value is different to different UE, then inconvenience can be brought.For example, it is assumed that being ordered comprising power control
The UE-group DCI of order is transmitted in time slot n, and the k value of UE1 is k1, and the time slot n+k1 of UE1 is ascending time slot, can be transmitted
The k value of PUCCH, UE2 are k2, and the time slot n+k2 of UE2 is descending time slot, cannot transmit PUCCH, as shown in figure 5, such case
Under, inconvenience can be brought.For UE different in a group, k value is also possible to different, can make the feelings in FDD in this way
Under condition, for the different demands of different UE, more flexible adjustment power, for example, the UE-group comprising power control command
DCI is transmitted in time slot n, and the k value of UE1 is k1, and the power control command of UE1 can apply the PUCCH transmitted on time slot n+k1
Power adjustment, the k value of UE2 is k2, and the power control command of UE2 can apply the PUCCH's transmitted on time slot n+k2
Power adjustment, as shown in Figure 6.
Or k value is determined by the way that agreement is default, for different UE, k value is identical.
The method is easier to realize, the signaling overheads needed is smaller, it can however not comparing the flexibly adjustment timing
Relationship.
Method two:
The transmission of UE-group power control command and the PUCCH of application these power control commands adjustment power transmit it
Between there are a timing relationships, that is to say, that UE-group power control command time slot n-k transmit, using these power controls
The PUCCH of system order adjustment power is transmitted in time slot n, and UE is in such a way that explicit signaling and physical layer signaling combine, Huo Zhetong
It crosses physical layer signaling and obtains k value, k is an integer more than or equal to 0, which is known as TPC timing relationship.For example, UE
A timing relationship set is obtained by explicit signaling (for example, system information, high-level signaling), for example, timing relationship collection is combined into
Then { k0, k1, k2, k3 }, referred to as TPC timing relationship set pass through the specific time in physical layer signaling instruction set
Spacing value, the TPC timing relationship indicated value of UE-group is with UE-group power control command and using the control of UE-group power
The corresponding relationship of the time interval ki of order is made, as shown in table 6.This method can dynamically adjust UE-group power control
Timing relationship between order and the PUCCH transmission of application these power control commands adjustment power, can adjust more in time
Power.
| The TPC timing relationship indicated value of UE-group | The time interval ki of UE-group power control command and application UE-group power control command |
| 00 | k0 |
| 01 | k1 |
| 10 | k2 |
| 11 | k3 |
Table 6
Be described below several determining timing relationship set and by physical layer signaling instruction set in one it is specific when
Between spacing value mode.
Mode one:
The timing relationship set of the UE of transmission power control command is identical in same UE-group DCI, and UE passes through
Explicit signaling (for example, system information, high-level signaling) obtains, for example, timing relationship collection is combined into { k0, k1, k2, k3 }.It is transmitting
In addition to the power control command of each UE of transmission in the DCI of UE-group power control command, a specific UE- is also transmitted
The TPC timing relationship of group indicates information, UE-group power of the value as UE being used to refer in timing relationship set
Time interval ki between control command and the PUCCH of application UE-group power control command adjustment power, the timing relationship
It indicates that the time interval value of information instruction is applied to all UE in the UE-group, that is, indicates the UE- of all UE in the group
Time interval ki between group power control command and the PUCCH of application UE-group power control command adjustment power, such as
Shown in Fig. 7, for example, the information in the DCI of the UE-group of transmission is { TPC1, TPC2 ..., TPCn ..., TPCN, UE-group
TPC timing relationship indicate information, N is indicated in the DCI of the UE-group power control command comprising N number of power control command,
The TPC timing relationship instruction information field of UE-group includes L bit (for example, L is 2), the TPC timing relationship instruction of UE-group
The value of information and UE-group power control command and application UE-group power control command adjustment power PUCCH between when
Between be spaced ki corresponding relationship it is as shown in table 6.
Mode two:
The TPC timing relationship set of the different UE of transmission power control command is not identical in same UE-group DCI
, for example, UE obtains the TPC timing relationship set of UE by explicit signaling (for example, high-level signaling), alternatively, UE-group
The TPC timing relationship set of the UE of transmission power control command and the HARQ timing relationship set of the UE are identical in DCI, for example,
The TPC timing relationship collection of UE1 is combined into { k0_1, k1_1, k2_1, k3_1 }, the TPC timing relationship collection of UE2 be combined into k0_2, k1_2,
K2_2, k3_3 }.In the DCI of transmission UE-group power control command other than transmitting the power control command of each UE,
The TPC timing relationship for also transmitting a specific UE-group indicates information, for UE all in UE-group, UE-group
TPC timing relationship instruction the value of information be identical, but due to the timing relationship set of different UE be it is different, respectively
Time between the UE-group power control command of a UE and the PUCCH of application UE-group power control command adjustment power
It is also likely to be different for being spaced ki.The time interval value of different UE is applied to different UE, that is, indicates each UE in the group
The time interval ki of UE-group power control command and application UE-group power control command, as shown in figure 8, for example, passing
Information in defeated DCI is { the TPC timing relationship of TPC1, TPC2 ..., TPCn ..., TPCN, UE-group indicate information }, N
Indicate that, comprising N number of power control command in the DCI of the UE-group power control command, the TPC timed-shutoff of UE-group is meant
Show that information field includes 2 bits, the TPC timing relationship instruction value of information and UE-group power control command of UE-group and application
The corresponding relationship that UE-group power control command adjusts the time interval ki between the PUCCH of power is as shown in table 7.For example,
The TPC timing relationship indicated value of UE-group is 01, for UE1, UE-group power control command and using UE-group function
It is k1_1 that rate control command, which adjusts the time interval between the PUCCH of power,；For UE2, UE-group power control command with
It is k1_2 using the time interval between the PUCCH of UE-group power control command adjustment power.
| The TPC timing relationship indicated value of UE-group | The time interval ki of UE1 | The time interval ki of UE2 | … | The time interval ki of UEN |
| 00 | k0_1 | k0_2 | k0_N | |
| 01 | k1_1 | k1_2 | k1_N | |
| 10 | k2_1 | k2_2 | k2_N | |
| 11 | k3_1 | k3_2 | k3_N |
Table 7
The method can dynamically adjust UE-group power control command and using UE-group power control command
Time interval is easier to realize, the signaling overheads needed is smaller.
Mode three:
In same UE-group DCI the TPC timing relationship set of the UE of transmission power control command be it is different or
Person is identical, for example, UE obtains the TPC timing relationship of UE by explicit signaling (for example, system information or high-level signaling)
Set, alternatively, the HARQ of the TPC timing relationship set of the UE of transmission power control command and the UE timing in UE-group DCI
Set of relationship is identical, for example, the TPC timing relationship collection of UE1 is combined into { k0_1, k1_1, k2_1, k3_1 }, the TPC timed-shutoff of UE2
Assembly is combined into { k0_2, k1_2, k2_2, k3_3 }.In addition to transmitting each UE in the DCI of transmission UE-group power control command
Power control command, also respectively correspond each UE and transmit the TPC timing relationship of a specific UE-group and indicate information.No
TPC timing relationship instruction Information application with UE indicates the UE-group power control command of the UE and answers in different UE
With UE-group power control command adjustment power PUCCH between time interval ki, as shown in figure 9, for example, transmission
Information in DCI is that { the TPC timing relationship of TPC1, UE-group indicate information 1, TPC2, the TPC timing relationship of UE-group
Indicate information 2 ..., the TPC timing relationship of TPCN, UE-group indicate information N }, N indicates the UE-group power control command
DCI in include N number of power control command, each UE-group TPC timing relationship instruction information field include 2 bits, UE-
The TPC timing relationship instruction value of information of group is with UE-group power control command and using UE-group power control command
The corresponding relationship for adjusting the time interval ki between the PUCCH of power is as shown in table 8.
| The TPC timing relationship indicated value of the UE-group of UE1 | The time interval ki of UE1 |

The method can dynamically adjust UE-group power control command and using UE-group power control command
Time interval, and the case where being directed to different UE, determines TPC timing relationship respectively, the signaling overheads needed is bigger.
Method three:
The implicit signaling that UE is sent by receiving base station obtains UE-group power control command and applies these power controls
Timing relationship between the PUCCH transmission of system order adjustment power, that is to say, that UE-group power control command is in time slot n-
K transmission is transmitted using the PUCCH of these power control commands adjustment power in time slot n, and UE is sent implicit by reception base station
Signaling obtains k value, and k is an integer more than or equal to 0.
For example, it is assumed that UE has been configured with HARQ timing relationship set, then, each UE selects the HARQ timed-shutoff of the UE
The value of a determining element in assembly conjunction is as the UE-group power control command of the UE and using these power controls
Time interval k value between the PUCCH transmission of order adjustment power.For example, the UE-group power control command of UE and application
These power control commands adjustment power PUCCH transmission between time interval k value be in HARQ timing relationship set most
Small value is (alternatively, maximum value；Or the smallest value, and time slot n is ascending time slot；Or maximum value, and time slot n is uplink
Time slot).For example, the HARQ timing relationship collection of UE is combined into { 1,2,3,4 }, the minimum value in HARQ timing relationship set is 1, then should
Between time between the PUCCH transmission of the UE-group power control command and application these power control commands adjustment power of UE
It is divided into 1.Or.For example, the PUCCH of the UE-group power control command of UE and application these power control commands adjustment power
Time interval k value between transmission is first value in HARQ timing relationship set, and e.g., the HARQ timing relationship collection of UE is combined into
{ 1,2,3,4 }, first value in HARQ timing relationship set are 1, then the UE-group power control command of the UE and application
It is 1 that these power control commands, which adjust the time interval between the PUCCH transmission of power,.
The method does not need additional physical layer signaling expense, it can however not comparing the flexibly adjustment timing relationship.
This method determines that UE-group power control command and the PUCCH of application these power control commands adjustment power pass
The method of time interval between defeated can be applied to determine UE-group power control command and apply these power control commands
The time interval between the PUSCH transmission of power is adjusted, is only changed by the UE-group power control command for PUCCH
For the UE-group power control command of PUSCH, PUCCH tiger is at PUSCH, and the HARQ timing relationship set of UE configuration is changed
At the set of the time interval slave the PUSCH that UL DCI is dispatched to the DCI of UE configuration.
Method four:
UE obtains UE-group power control command and application these power controls life using default HARQ timing relationship
The timing relationship between the PUCCH transmission of adjustment power is enabled, default HARQ timing relationship here is referred to for by public
Timing relationship between the HARQ transmission of the PDSCH and the PDSCH of the PDCCH scheduling of search space, default HARQ timed-shutoff
System can be default by agreement or be indicated by system information.That is, the PDSCH that the PDCCH of public search space is dispatched
Time slot n-k transmit, the HARQ transmission of the PDSCH in time slot n, then, UE time slot n-k receive UE-group power control life
It enables, which is applied to time slot n by UE.
Embodiment two
In new wireless (NR, New Radio) communication system, introducing in one time slot has multiple PUCCH to transmit, example
Such as, there are two time-multiplexed PUCCH to transmit in a time slot n, and the PUCCH of front is denoted as PUCCH-1, subsequent PUCCH
It is denoted as PUCCH-2, as shown in Figure 10.At this point, the DCI of transmission TPC and the uplink UCI transmission of application TPC progress power control
Between timing relationship as unit of time slot, for example, time slot n transmission include TPC DCI, time slot n+k transmission application should
The uplink UCI of TPC progress power control.Here TPC include dispatch PDSCH DCI in TPC and UE-group it is public
TPC in DCI.At this moment the power control for how carrying out multiple PUCCH in a time slot has following several method.
Method one:
When there are at least two PUCCH to send according to time-multiplexed mode in a time slot, each PUCCH is counted respectively
Calculate the accumulated value g (i) of close-loop power control.For example, there are two time-multiplexed PUCCH to transmit in a time slot i, front
PUCCH is denoted as PUCCH-1, and subsequent PUCCH is denoted as PUCCH-2, and for PUCCH-1, the accumulated value of close-loop power control is denoted as
G_1 (i), for PUCCH-2, the accumulated value of close-loop power control is denoted as g_2 (i).δPUCCHIt is according to transmission power control command
The power adjustment that (TPC command) is obtained, g_1 (i) and g_2 (i) can be according to formulaWithIt calculates separately and obtains, wherein
miRefer to time slot i-miTPC command be unsatisfactory for time delay processing requirement.
Specifically, g (i-1) is equal to the last one in time slot i-1 if having multiple PUCCH to transmit in time slot i-1
The accumulated value of the close-loop power control of PUCCH, for example, there are two time-multiplexed PUCCH to transmit in a time slot i-1, it is preceding
The PUCCH in face is denoted as PUCCH-1, and subsequent PUCCH is denoted as PUCCH-2, for PUCCH-1, the accumulated value of close-loop power control
It is denoted as g_1 (i-1), for PUCCH-2, the accumulated value of close-loop power control is denoted as g_2 (i-1), then, g (i-1) is equal to g_2
(i-1)。
Here M is directed to the total of the power control command of time slot i
Number.For example, M is equal to 3, power control command TPC-0, TPC-1 are received respectively in time slot i-k0, time slot i-k1 and time slot i-k2
And TPC-2, δ is calculated separately out according to power control command TPC-0, TPC-1 and TPC-2PUCCH(i-k0), δPUCCH(i-k1),
δPUCCH(i-k2), miRefer to time slot i-miTPC command be unsatisfactory for time delay processing requirement, the TPC command of this time slot cannot
Applied to calculating g_1 (i).
For example, as shown in figure 11, long PUCCH is denoted as PUCCH-1, and short PUCCH is denoted as PUCCH-2, passed in time slot n
It is defeated, power control command TPC-0, TPC-1 and TPC-2 are received respectively in time slot n, time slot n-1 and time slot n-2.For long
The power control command TPC-1 and TPC-2 of PUCCH-1, time slot n-1 and time slot n-2 meet delay requirement, can use them and obtain
To power adjustment δPUCCH(n-1), δPUCCH(n-2), and the power control command TPC-0 of time slot n is before UE is received, and UE is
Started the long PUCCH-1 of transmission, therefore, the power adjustment δ that the power control command TPC-0 of time slot n is obtainedPUCCH(n) not
The accumulated value g_1 (n) of the close-loop power control of PUCCH-1, therefore, g_1 (n)=g (n-1)+δ can be used to calculatePUCCH(n-1)+
δPUCCH(n-2)；For short PUCCH-2, time slot n, time slot n-1 and time slot n-2 power control command TPC-0, TPC-1 and
TPC-2 meets delay requirement, can use them and obtains power adjustment δPUCCH(n), δPUCCH(n-1), δPUCCH(n-2), then
The accumulated value of close-loop power control, therefore, g_2 (n)=g (n-1)+δ are calculated using power adjustmentPUCCH(n)+δPUCCH(n-1)
+δPUCCH(n-2).And the g (n) that the accumulated value for being used for the close-loop power control of time slot n+1 calculates is equal to g_2 (n).TPC above
Order can be the TPC command that the DCI in the PDCCH of scheduling PDSCH includes, the TPC being also possible in the public DCI of UE-group
Order.
Method two:
It is unified to each PUCCH to count when thering are at least two PUCCH to send according to time-multiplexed mode in a time slot
Calculate the accumulated value g (i) of close-loop power control.For example, there are two time-multiplexed PUCCH to transmit in a time slot i, front
PUCCH is denoted as PUCCH-1, and subsequent PUCCH is denoted as PUCCH-2, and for PUCCH-1 and PUCCH-2, close-loop power control tires out
It is value added be it is identical, be denoted as g (i).δPUCCHIt is the power adjustment obtained according to transmission power control command (TPC command)
Value, g (i) can be according to formulaIt is calculated.
Specifically,Here M is directed to the power control command of time slot i
Total number receives power control command TPC-0 in time slot i-k0, time slot i-k1 and time slot i-k2 for example, M is equal to 3 respectively,
TPC-1 and TPC-2 calculates separately out δ according to power control command TPC-0, TPC-1 and TPC-2PUCCH(i-k0), δPUCCH(i-
K1), δPUCCH(i-k2), miRefer to time slot i-miTPC command be unsatisfactory at the time delay of at least one PUCCH power control
Reason requires, and the TPC command of this time slot may not apply to calculate g (i).For example, as shown in figure 11, long PUCCH is denoted as PUCCH-
1, short PUCCH is denoted as PUCCH-2, transmits in time slot n, receives power control life respectively in time slot n, time slot n-1 and time slot n-2
Enable TPC-0, TPC-1 and TPC-2.For long PUCCH-1, time slot n-1 and time slot n-2 power control command TPC-1 and
TPC-2 meets delay requirement, and the power control command TPC-0 of time slot n is before UE is received, and it is long that UE has begun transmission
PUCCH-1, therefore, the power adjustment δ that the power control command TPC-0 of time slot n is obtainedPUCCH(n) it is not able to satisfy PUCCH-1's
The delay requirement of power control；For the power control command TPC-0 of short PUCCH-2, time slot n, time slot n-1 and time slot n-2,
TPC-1 and TPC-2 meets the delay requirement of the power control of PUCCH-2, that is, the only power control of time slot n-1 and time slot n-2
It orders TPC-1 and TPC-2 while meeting the delay requirement of the power control of PUCCH-1 and PUCCH-2, and time slot n power control
Order TPC-0 is unsatisfactory for the delay requirement of the power control of PUCCH-1, therefore the power adjustment obtained using TPC-1 and TPC-2
Value δPUCCH(n-1), δPUCCH(n-2) accumulated value of close-loop power control, g (n)=g (n-1)+δ are calculatedPUCCH(n-1)+δPUCCH(n-
2)。
Embodiment three
In new wireless (NR, New Radio) communication system, it is possible that the DCI of a transmission TPC command is another
Before the DCI of a transmission TPC command, and the PUCCH for applying the TPC command of previous transmissions to carry out power control is transmitted after application
The case where after the PUCCH transmission of the TPC command progress power control of face transmission.For example, the DCI-1 of transmission TPC command TPC-1
It is transmitted in time slot n-k-l, the DCI-2 for transmitting TPC command TPC-2 is transmitted in time slot n-k, carries out power control using TPC-1
PUCCH-1 is transmitted in time slot n+p, is transmitted using the PUCCH-2 that TPC-2 carries out power control in time slot n, as shown in figure 12.
At this moment the power control for how carrying out PUCCH has following several method.
Method one:
Power control for the PUCCH transmitted in time slot n, uses time slot n-kmTPC command in the DCI of transmission (is wanted
Ask: the TPC be not applied to before close-loop power control accumulated value calculating, according to TPC timing relationship, time slot n-kmIt passes
TPC command in defeated DCI is applied to the power control of the PUCCH of time slot n transmission) and in time slot n-kmIt transmits before
In DCI TPC command (it is required that the TPC be not applied to before close-loop power control accumulated value calculating, it is fixed according to TPC
When relationship, time slot n-kmThe TPC command in DCI transmitted before is applied to the power control of the PUCCH of time slot n+p transmission, and p is
Positive integer more than or equal to 1) PUCCH power control is carried out together.
Specifically, as shown in figure 12, the DCI-1 for transmitting TPC command TPC-1 is transmitted in time slot n-k-l, transmission TPC life
The DCI-2 of TPC-2 is enabled to transmit in time slot n-k, according to TPC timing relationship, TPC-1 carries out the PUCCH-1 of power control in time slot n
+ p transmission, the PUCCH-2 that TPC-2 carries out power control is transmitted in time slot n, at this point, the closed loop of the PUCCH-2 in time slot n transmission
The power adjustment δ that the accumulated value of power control is obtained using TPC-1 and TPC-2PUCCH(1) and δPUCCH(2) it is calculated, i.e. g
(n)=g (n-1)+δP U(C1)C+δHP U(C2)C。HSince TPC-2 is time slot n-kmTPC command in the DCI of transmission is application
In the power control of the PUCCH of time slot n transmission TPC (TPC be not applied to before close-loop power control accumulated value
Calculate), and TPC-1 is time slot n-kmThe DCI transmitted before, and according to TPC timing relationship in time slot n-kmThe DCI transmitted before
In TPC command be the TPC applied to the power control of the PUCCH transmitted after time slot n (before the TPC is not applied to
The calculating of the accumulated value of close-loop power control), therefore according to the method for front, the power adjustment obtained using TPC-1 and TPC-2
Value δPUCCH(1) and δPUCCH(2) carry out calculating the accumulated value of the close-loop power control of time slot n.In the PUCCH-1 of time slot n+p transmission
Close-loop power control the accumulated value power adjustment δ that does not utilize TPC-1 to obtainPUCCH(1) it is calculated, i.e. g (n+p)=g
(n+p-1), since TPC-1 is time slot n-kmThe TPC command in DCI transmitted before is applied to the PUCCH-1 of time slot n+p transmission
Power control TPC, but the TPC-1 be once applied to before PUCCH-2 close-loop power control accumulated value calculating, because
This, the calculating of the accumulated value for the PUCCH-1 close-loop power control that TPC-1 is no longer applied to.
In this way, the calculating of base-station transmitting-power control command is calculated according to time order and function, i.e. TPC-2 be
It is calculated on the basis of TPC-1, therefore, PUCCH-2 should carry out power control using TPC-1 and TPC-2.
TPC timing relationship described above refers to the DCI of transmission TPC command and carries out power control using the TPC
Timing relationship between PUCCH.For example, being ordered in time slot n transmission using the TPC in time slot n-k DCI of the transmission including TPC command
The PUCCH for carrying out power control is enabled, the corresponding time relationship between the PUCCH and DCI is known as TPC timing relationship.
Method two:
Power control for the PUCCH transmitted in time slot n, in time slot n-kmThe DCI of transmission, and according to TPC timed-shutoff
System, time slot n-kmTPC command in the DCI of transmission is the TPC, PUCCH applied to the power control of the PUCCH of time slot n transmission
The calculating of the accumulated value of close-loop power control is according to time slot n-kmTPC in the DCI of transmission is carried out.Specifically, such as Figure 12 institute
Show, the DCI-1 for transmitting TPC command TPC-1 is transmitted in time slot n-k-l, and the DCI-2 for transmitting TPC command TPC-2 is passed in time slot n-k
Defeated, according to TPC timing relationship, the PUCCH-1 that TPC-1 carries out power control is transmitted in time slot n+p, and TPC-2 carries out power control
PUCCH-2 transmitted in time slot n, the TPC-1 calculating close-loop power control that PUCCH-1 transmit using DCI-1 in time slot n-k-l
Accumulated value；PUCCH-2 calculates the accumulated value of close-loop power control using DCI-2 in the TPC-2 that time slot n-k is transmitted.
