Specific embodiment

To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention Embodiment be described in detail.It should be noted that in the absence of conflict, in the embodiment and embodiment in the application Feature can mutual any combination.

Step shown in the flowchart of the accompanying drawings can be in a computer system such as a set of computer executable instructions It executes.Also, although logical order is shown in flow charts, and it in some cases, can be to be different from herein suitable Sequence executes shown or described step.

In wireless communication system, send to reduce sending device power consumption and reduce unnecessary high power to other transmission Caused by interfere, need to carry out transmission power control transmission.Size, the maximum of the transceiver of communicating pair of communication range Send bandwidth occupied for power and receiving sensitivity, the modulation coding scheme of data and rate, the frequency band of work, transmission etc. because Element can all influence to send power.Generally require under conditions of meeting the received signal quality requirement of receiving end, use as far as possible compared with Low transmission power.

In the general communication technology, communication node 1 sends reference signal, and communication node 2 is measured according to the reference signal and saved Point 1 arrives the path loss (Pathloss, PL) of node 2.PL is to be received with the transmission power of the reference signal of node 1 with node 2 Reference signal reception power difference calculate.Assuming that the PL that node 2 arrives the transmission channel of node 1 arrives the biography of node 2 with node 1 The PL of defeated channel is identical, then node 2 can use the transmission function of transmission of the above-mentioned PL calculate node 2 as sending node to node 1 Rate.Since PL is folk prescription planar survey as a result, therefore the factor belongs to ring opening moiety in sending power.Node 1 receives biography It is parsed after defeated, quality is that node 2 provides the information of power adjustment based on the received, which belongs to close-loop power control.

In LTE, the link of base station to terminal is downlink, and the link of terminal to base station is uplink.Downlink Power by base station according to it is each scheduling UE channel measurement and dispatching algorithm determine.The power control of uplink is out The mode of ring combination closed loop.In addition, there are also specific amounts relevant to transmission, such as transmission rate, modulation and coding strategy (Modulation and Coding Scheme, MCS) grade, transmission bandwidth etc. also will affect power.

Here is the hair of the Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH) of LTE Rating formula is sent, the parameters for influencing power are illustrated as example.

Subscript c refers to cell cell in above formula, supports the every of carrier wave polymerization (Carrier Aggregation, CA) function The corresponding cell cell of a member carrier (Component Carrier, CC).From above formula it can be seen that, rating formula In each parameter be to discriminate between cell configuration/calculate.When all descriptions are not particularly illustrated frequency domain herein, It is described both for a CC.It should be pointed out that all parameters of this paper can expand on multiple CC, it is only necessary to Parameter by the relevant configuration of power and calculating is each CC separate configurations.

The power P of uplink PUSCH_PUSCHRing opening moiety by target received power P_{O_PUSCH}, path loss amount PL and path loss Factor-alpha determines that wherein target received power is divided into cell grades of cell and UE grades of parameters, is all determined by base station and is allocated to UE；And Closed loop portion is then that base station according to the gap of measurement result and target determines closed-loop power control adjustment amount, to transmit power control commands (δ of PUSCH is directed in Transmit Power Control Command, TPC Command, i.e. DCI_PUSCH) mode notify UE.UE safeguards the power adjustment f (i) of a local, is updated according to transmission power control commands, is reached using above-mentioned formula and closed The purpose of ring control power.Wherein, i is subframe number, and Δ TF is the relevant power excursion of MCS, and PCMAX is the maximum power of UE Limitation.

The cell grade target received power P0_nominal of LTE be to discriminate between PUSCH (semi-static, dynamic, message 3MSG3) and Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH), respectively corresponds different Block Error Rates (Block Error Ratio, BLER) demand.UE grades of target received power parameter P0_UE_specific are also to discriminate between above several Item is configured, and is to compensate for systematic bias, the error being arranged such as PL evaluated error, absolute output power.

F (i) is updated according to transmission power control commands and is divided into two ways: accumulating and absolute-value sense, wherein absolute value side Formula is the power adjustment f (i) that the local UE is directly updated with the transmission power control commands that base station is sent, and accumulating is then sent out by base station The history value of the power adjustment of the transmission power control commands and the local the UE sent determines the power adjustment f (i) of the local UE jointly. It should be noted that f (i) here represents the closed power adjustment amount of the local UE.

Power control in long term evolution (Long Term Evolution, LTE) technology is related with several factors, such as road Diameter loss, target received power, maximum transmission power, closed power adjustment amount, the bandwidth of transmission, rate of transmission etc..

5G technology introduces the transmission mode of wave beam, and base station and UE support multi-beam.When work in beam modes, function Rate calculates the characteristic for needing to consider wave beam.In order to support the mode of wave beam, power contorl parameters are divided into 3 parts configuration: open loop function Control parameter, closed-loop power control parameter, the RS parameter of path loss.Wherein each part supports configuration multiple, i.e., open loop power control parameter (or its Set) J can be at most configured, the number of each open loop power control parameter (or its set) is j；Path loss RS parameter (or its collection Close) K can be at most configured, the number of the RS parameter (or its set) of each path loss is k；Closed-loop power control parameter (or its set) L can be at most configured, the number of each closed-loop power control parameter (or its set) is l；Wherein, j, k, l are positive integer, and j is Greater than 0 be less than or equal to J integer, k be greater than 0 be less than or equal to K integer, l be greater than 0 be less than or equal to L integer, and J, K, L is the integer greater than 0.

If UE supports multiple wave beams (or wave beam group), base station configures each possible wave beam (or wave beam group) and open loop Power control parameters, closed-loop power control parameter, the association between the RS parameter of path loss.Wave beam (or wave beam group) can be provided by reference to signal Source instruction.

Reference signal includes at least one of: uplink detection signal (Sounding Reference Signal, SRS), Channel state information reference signals (Channel State Information Reference Signal, CSI-RS), it is auxiliary same It walks block (secondary Synchronization Block, SSB), Phase Tracking reference signal (Phase Tracking Reference Signal, PTRS), track reference signal (Tracking Reference Signal, TRS), demodulation reference letter Number (Demodulation Reference Signal, DMRS).

The uplink that base station is UE indicates reference signal resource, and UE is made to obtain power associated by the reference signal resource Control parameter.

It is exemplified below:

The PUSCH transmission that base station is UE configures J1 open loop power control parameter (or it is gathered), the RS parameter of K1 path loss (or It is gathered), L1 closed-loop power control parameter (or its set).

Base station is the transmission mode that UE configures PUSCH, such as codebook-based transmission (codebook based ), or the transmission based on non-code book (non-codebook based transmission) transmission.

Base station is uplink detection signal resource collection (the SRS resource that UE configures the transmission mode based on PUSCH Set), including at least one uplink detection signal resource (SRS resource).

Base station is that UE sends Downlink Control Information (Downlink Control Information, DCI), including tune Degree request instruction (Schduling Request Indication, SRI), SRI is determined for prelisting for PUSCH transmission Code.The SRI set indicated in the DCI of different PUSCH transmission modes may be different.For example, the SRI of codebook-based transmission gathers May there are 2 SRI, each SRI to represent a SRS resource (Resource)；The SRI set of transmission based on non-code book may have 15 SRI, each SRI represent SRS resource or multiple SRS resources.

Base station is that UE configures being associated with for each of the SRI set indicated in DCI member SRI and at least one of: Open loop power control parameter (or its set) number, RS parameter (or its set) number of path loss, closed-loop power control parameter (or its set) Number.

The power control parameters of UE PUSCH transmission are informed by the SRI in DCI in base station.

SRS resource, SRS resource set, power control parameters are carried out based on the frequency domain unit of at least one of Configuration: BWP, CC.

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 method etc., quality, base station need to judge that subsequent scheduling needs which is adjusted based on the received Factor, such as improve modulation coding scheme, improve transmission power.But the current transmission power of UE is not known in base station, also not It knows whether and transmission power can be improved.Therefore there are a kind of mechanism in LTE, UE sends 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 actual uplink needs Power is sent, this PHR is known as true PHR.The transmission power that actual uplink needs is related at least one following parameter: Transmit occupy frequency domain width, transmission occupy frequency domain position, the data rate of transmission, the MCS of transmission, transmission format, open Ring 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, for PUSCH transmission, the PHR of type 2 is for PUCCH transmission or PUCCH+ PUSCH transmission, the PHR of type 3 is for SRS transmission.

By taking the transmission of PUSCH as an example, when UE is in the PUSCH transmission phase of the uplink BWP b of the carrier wave f of serving cell c PUSCH is transmitted on (transmission period) i, then the calculating such as following formula of the true PHR of Class1:

Wherein, P_{CMAX, f, c}(i),P_{O_PUSCH, b, f, c}(j),α_{B, f, c}(j),PL_{B, f, c}(q_d),Δ_{TF, b, f, c} (i) and f_{B, f, c}(i, l), not subscripting b, when subscript of f, c, are similar with the physical quantity meaning of the corresponding symbol of above-mentioned (formula 1), this Place carries subscript b, and f, c specify corresponding physical quantity in the configuration of the uplink BWP b of the carrier wave f of serving cell c.In addition, herein I refer to transmission phase of PUSCH, the subframe number slightly difference with above-mentioned (formula 1), but all there is no harm in as the unit of time domain Hinder the understanding of the present invention.J is the index of the open loop power control parameter sets of PUSCH transmission, q_dIt is matching for the RS that PL measurement uses The index of set is set, above-mentioned k, l are closed-loop power control numbers.

The calculating such as following formula of virtual PHR:

Wherein,For the maximum transmission power value under the limitation of some conditions.

UE triggers PHR when trigger condition meets.Trigger condition includes at least one of: the cycle timer of PHR arrives The PL value variation thresholding of phase, detection exceed thresholding, and PHR's reports interval to be greater than minimum interval.

After triggering PHR, UE sends PHR when there is enough resource transmission PHR.

It is after triggering PHR, before transmission PHR that physical layer, which calculates PHR,.At the time of calculating PHR at least by the following conditions One of determine: triggering PHR after, receive comprising uplink license (UL grant) information DCI, receive the UL for being large enough to hold PHR The DCI of grant information includes the time slot where the uplink of PHR comprising the subframe where the uplink of PHR.

For example, receiving the UL grant information for being large enough to hold PHR, then according to UL after the PHR trigger condition of UE meets Uplink transmission parameter in grant information calculates PHR, and PHR is sent in the ascending resource of UL grant information instruction to base station.

CA or more BWP scene is polymerize for carrier wave, for scheduled serving cell/BWP of uplink in UL grant, Actual PHR is calculated, and for there is no serving cell/BWP of scheduling of upstream transmissions in UL grant, calculate virtual PHR.

Assuming that base station is the RS that UE configures K1 PL, the value range of number k, k are 0~K1-1.The K1 for estimating The RS of meter PL is known as the RS set of the first PL.

The subset of the RS set of first PL is configured the domain SRI in the DCI with PUSCH and is associated with, which is known as the 2nd PL RS set.For example, having K1_1 RS relevant with the SRI in the DCI of PUSCH in the RS of K1 PL of configuration.K1_1≤ Both K1 is integer.

Alternatively, determining that the RS of the 2nd PL gathers using predefined mode.For example, when not including SRI in the DCI of PUSCH When domain, the RS of the 2nd PL set be predefined as first in the RS set of the first PL or front several.For another example, exist Before RRC connection, UE can not obtain the UE specific information of base station configuration, so UE oneself can determine the RS collection for PL estimation It closes.

Base station is that UE configures L1 closed-loop power control, and the value range of number l, l are 0~L1-1.The L1 closed-loop power control Referred to as the first closed-loop power control set.

The subset of first closed-loop power control set is configured the SRI in the DCI with PUSCH and is associated with, which is known as second and closes Ring power control set.For example, having L1_1 closed-loop power control related with the SRI in the DCI of PUSCH in L1 closed-loop power control of configuration Connection.Both L1_1≤L1 is integer.

Alternatively, determining the second closed-loop power control set using predefined mode.For example, when not including in the DCI of PUSCH When the domain SRI, the second closed-loop power control set be predefined as first in the first closed-loop power control set or front several.

The k and l for being associated with the same SRI are indirect associations.It is to be associated with that the k and l of indirect association, which are referred to as k with l, 's.

The RS set of the 2nd PL determined using predefined mode and the second closed loop function determined using predefined mode Control set is associated.

Base station is that UE configures J1 open loop power control parameter sets, and the value range of number j, j are 0~J1-1.The J1 Open loop power control parameter sets are known as the first open loop power control parameter sets.

The subset of first open loop power control parameter sets is configured the SRI in the DCI with PUSCH and is associated with, which is known as Two open loop power control parameter sets.For example, having J1_1 open loop power control parameter sets in J1 open loop power control parameter sets of configuration It is relevant with the SRI in the DCI of PUSCH.J1_1≤J1, both integer.

Alternatively, determining the second open loop power control parameter sets using predefined mode.For example, not wrapped when in the DCI of PUSCH When including the domain SRI, the second open loop power control parameter sets are predefined as first in the first open loop power control parameter sets or front Several.

C. a PHR is reported for the associated l of number k of the RS of each PL.

If multiple k are associated with the same l, the average value of the corresponding PL value of multiple k is used.I.e. PHR number be and satisfaction The number of the corresponding k of the RS of condition relevant l.

D. it is directed to each k and reports a PHR with the combination of the associated l of k.

The information for the j that calculating PHR is used is indicated for each PHR, or indicates the PHR reported using the SRI of configuration association { j, k, l }.

E. each CC/BWP/BWP grouping reports the PHR of predetermined number.For example, predetermined number is 1.

Then a power control parameters { j, k, l } is selected to calculate PHR, or according to multiple power control parameters { j, k, l }

Multiple PHR calculate a comprehensive PHR.

Above-mentioned each PHR can be true PHR or virtual PHR.

Above-mentioned l refers to the first closed-loop power control (set) number or the second closed-loop power control (set) number.Each l refers to pair Each closed-loop power control number in the first closed-loop power control (set) or the second closed-loop power control (set) answered.

Above-mentioned each { k, l } refers to that the RS set number of the 2nd relevant PL and the second closed-loop power control (set) are compiled It is number right.

Above-mentioned j refers to the first open loop power control parameter sets number or the second open loop power control parameter sets number.

Base station passes through RRC signaling perhaps MAC CE or physical layer signaling, the parameter of UE PHR is notified, alternatively, UE root The configuration parameter of PHR is determined according to preparatory rule.

The configuration parameter of PHR includes at least following one: a PHR is reported for the number k of the RS of each PL, for every A l reports a PHR, reports a PHR for the associated l of number k of the RS of each PL, associated for each k and with k The combination of l reports a PHR, and each CC/BWP/BWP grouping reports the PHR of predetermined number.

UE determines that the configuration parameter of PHR includes at least one following characteristic:

1. the MAC layer of base station notice UE or UE notifies the physical layer of the UE, at least a set of power control parameters { j, k, l } should UE calculates the PHR of corresponding { j, k, l }.

The physical layer of the UE reports at least one PHR to the MAC layer of the UE, and the MAC layer of the UE is by least one PHR It is reported to base station.

Alternatively, the physical layer of the UE report at least one PHR give the UE MAC layer, the MAC layer of the UE to this at least one PHR selects one or several PHR and is reported to base station.

2. the MAC layer of base station notice UE or UE notifies at least a set of power control parameters { j, k, l } of the physical layer of the UE, should The physical layer of UE calculates the PHR of corresponding { j, k, l }, determines a comprehensive PHR value.

Physical layer is shown in the description of preferred embodiment 3 according to the method that multiple PHR determine a comprehensive PHR value.

3. the MAC layer of base station notice UE or UE notifies the triggering type of the physical layer PHR of the UE, the physical layer of the UE The PHR of predetermined number is determined according to the type of triggering PHR.

Wherein, the triggering type of PHR is used to determine the power control parameters of PHR.

The triggering type of PHR is for determining the power control parameters of at least PHR of the CC/BWP of PHR trigger event generation.

The triggering type of PHR include at least following one: the period triggering PHR, the PHR of PL change triggers, increase or more New CC configuration increases or updates CC grouping, increases or update BWP, increases or updates BWP grouping, the parameter configuration of PHR becomes Change.

Preferred embodiment 5

Base station is that UE configures power control parameters, and the report cycle of PHR forbids the duration for continuously reporting PHR, the variation door of PL Limit.

UE starts the timer of PHR, and monitors the PL of RS in real time.

When timer expires, triggers period PHR and report.

When the PL variation of the RS of UE monitoring causes PHR to trigger, then the PHR for triggering PL variation is reported.

After PHR is triggered, when UE receive first be directed to the UE UL grant (uplink authorization) information newly transmitted, refer to Show that the UE has uplink transmission resource on some CC/BWP, then the PHR on the CC/BWP is true PHR.

As shown in figure 3, UE is configured for 3 CC.At the t1 moment, PHR is triggered, and receives respectively at t2 moment and t3 moment The UL grant information for re-transmission of CC#1 and CC#3.It is received in CC#1 to the UL grant information of new biography at the t5 moment, Middle instruction sends uplink at the t8 moment on CC#1.It may include PHR information in the uplink that the t8 moment sends.It should PHR information includes the PHR of all 3 CC.

It is true PHR to CC#1, PHR.

PHR on the other configurations CC/BWP of uplink (referred to as uplink CC/BWP) is true PHR or virtual PHR is determined one of in the following way:

1. receiving in first PDCCH for other corresponding uplink CC/BWP, after PHR is triggered if including this The UL grant information of UE, then the PHR of the CC/BWP is true PHR, is otherwise virtual PHR.

As shown in figure 3, in the PHR that the t8 moment sends, the virtual PHR including CC#2, and the t3 moment tune including CC#3 The true PHR that the uplink of degree determines.

2. being received in other correspondences while receiving the above-mentioned first UL grant information newly transmitted for being directed to the UE In first PDCCH of row CC/BWP, if the UL grant information comprising the UE, the PHR of the CC/BWP are true PHR, It otherwise is virtual PHR.

If not receiving PDCCH, the PHR of the CC/BWP is virtual PHR.

As shown in figure 3, since the UL grant information of first new biography is to receive at the t5 moment, and the moment does not receive To the UL grant information of CC#2 and CC#3, then in the PHR that the t8 moment sends, the virtual PHR including CC#2 and CC#3.

3. dispatching letter into the UL grant receiving the above-mentioned first UL grant information newly transmitted for the UE It ceases before coming into force, in first PDCCH for receiving other corresponding uplink CC/BWP, if the UL grant information comprising the UE, Then the PHR of the CC/BWP is true PHR, is otherwise virtual PHR.If not receiving PDCCH, the PHR of the CC/BWP is empty Quasi- PHR.

As shown in figure 3, since the UL grant information of first new biography was received at the t5 moment, the UL grant information tune The uplink at t8 moment is spent.Between t5 to t8, the UL grant information for the UE of CC#2 is not received, therefore CC#2 is virtual PHR.Between t5 to t8, the UL grant information for the UE of CC#2, therefore CC# are had received at the t6 moment 3 be true PHR.

The power control parameters { j, k, l } of true PHR are that the parameter of the uplink of corresponding UL grant message scheduling is true Fixed.

The indicating means of { j, k, the l } of PHR includes following one:

● do not need number and its { j, k, l } that explicit instruction, base station and UE determine m according to predefined mode.

● instruction m value determines { j, k, the l } of PHR according to the relationship of the m of pre-configuration and { j, k, l }.

● according to the incidence relation of the SRI of pre-configuration and { j, k, l }, use { j, k, the l } of the PHR that SRI instruction reports

As shown in figure 3, in CC#1, when including SRI in the UL grant information (relationship of description and DCI) at t5 moment, and And power control parameters { j, k, l } can determine that by the SRI, then this group of power control parameters { j, k, l } is used when the PHR of the CC#1 is calculated.It is no Then, the PHR of the CC#1 is using the power control parameters { j, k, l } defaulted.

The determination method of the power control parameters { j, k, l } of virtual PHR: being pre-configured M { j, k, l } set and be used for virtual PHR, According to determining one used in M of at least one following method or the PHR of predetermined number:

1) PHR for reporting { j, k, the l } of m=0 to M-1 in turn in sequence reports the corresponding PHR of 1 set every time, or Person reports the set of predetermined number PHR every time.

For example, { j, k, l } that M is 2, m=0 is { 1,0,0 }, { j, k, the l } of m=1 is { 2,1,1 }, reports 1 collection every time Close corresponding PHR.

It reports the PHR of { j, k, the l } of m=0 for 1st time, reports the PHR of { j, k, the l } of m=1 for the 2nd time, report m=0 the 3rd time { j, k, l } PHR, and so on.

For another example, { j, k, l } is respectively configured in 6 M, m=0 to m=5, reports the corresponding PHR of 2 { j, k, l } set every time. It then reports the PHR of { j, k, the l } of m=0 and m=1 for the 1st time, reports the PHR of { j, k, the l } of m=2 and m=3 for the 2nd time, on the 3rd time The PHR of { j, k, the l } of m=4 and m=5 is reported, the 4th reports the PHR of { j, k, the l } of m=0 and m=1, and so on.

The indicating means of { j, k, the l } of PHR includes following one:

2) according to determining m at the time of reporting.The m reported is the function of sending time.Report 1 set corresponding every time PHR, or the set of predetermined number PHR is reported every time.

Moment i=0 report the PHR of { j, k, the l } of m=0, moment i=1 report m=1 { j, k, l } PHR, moment i= 3 report the PHR of { j, k, the l } of m=0, and so on.

For another example, { j, k, l } is respectively configured in 6 M, m=0 to m=5, reports the corresponding PHR of 2 { j, k, l } set every time. Then moment i=0 report the PHR of { j, k, the l } of m=0 and m=1, moment i=1 report m=2 and m=3 { j, k, l } PHR, Moment i=3 report the PHR of { j, k, the l } of m=4 and m=5, moment i=4 report m=0 and m=1 { j, k, l } PHR, according to It is secondary to analogize.

Sending time refers to subframe number, and perhaps slot number perhaps number by frame number or OFDM symbol.

The indicating means of { j, k, the l } of PHR includes following one: base station and UE are according to predefined mode according to reporting The number and its { j, k, l } of m are determined at the time of PHR.

3) according to priority the PHR of { j, k, the l } of one or predetermined number is selected to report.1 set is reported to correspond to every time PHR, or report the set of predetermined number PHR every time.Priority determines that method includes at least one following:

● the small priority of pH value is high

For example, { j, k, l } that M is 2, m=0 is { 1,0,0 }, { j, k, the l } of m=1 is { 2,1,1 }, reports 1 collection every time Close corresponding PHR.UE is that two m calculate separately PH, selects the small m of pH value and reports.

● PL changes the height of priority greatly

For example, M is 2, respectively m=0 and m=1 configuration { j, k, l } report the corresponding PHR of 1 set every time.UE is two A m calculates separately the variation of the PL from the PHR moment that last time reports the m, selects the m that PL changes greatly and reports.

● related with the duration reported, being spaced the more long PHR not reported, then priority is higher

For example, M is 2, respectively m=0 and m=1 configuration { j, k, l } report the corresponding PHR of 1 set every time.UE is two A m calculates separately the timing from the PHR moment that last time reports the m, selects moment longest m and reports.

● when PHR triggering is caused by the variation of PL, m priority relevant to the RS that PL changes caused PHR triggering is high.

For example, if the PHR triggering of CC#2 is caused by the variation of PL, it is assumed that the PL of the RS number k=2 of PL, which changes, is more than Caused by thresholding, then the PHR of CC#2 should include the PHR of k=2.If M is that { j, k, the l } of 2, m=0 is { 1,0,0 }, m=1 { j, k, l } be { 2,2,1 }, then report the PHR of m=1.

The indicating means of { j, k, the l } of PHR includes following one:

For the CC that triggering PHR event occurs, the triggering type of PHR will affect the power control parameters { j, k, l } of the PHR of the CC Selection.

When PHR triggering is caused by the variation of PL, then the corresponding PHR of the CC, will at least include the PHR of the RS of PL variation.

As shown in figure 3, if the PHR triggering of CC#2 is the PL of the RS number k=2 of e.g. PL caused by the variation of PL Caused by variation is more than thresholding, then the PHR of CC#2 should include the PHR of k=2.

One of when true PHR does not include the PHR of PL variation of this part RS, in the following ways:

● the corresponding PHR of UL grant information is replaced with the PHR comprising this part RS.

● or increase the PHR of this part RS on the basis of UL grant information corresponding PHR.

One of ● when virtual PHR does not include the PHR of this part RS, in the following ways:

● the virtual PHR of script is replaced with the virtual PHR comprising this part RS.

● or increase the PHR of the RS of this part on the basis of virtual PHR originally.

After a PHR trigger event occurs, before reporting PHR, and there are other CC also to trigger PHR, and the PHR Caused by being the variation of PL, then the PHR on the CC of new PHR triggering should include at least the corresponding RS's of PHR newly triggered PHR。

As shown in figure 4, UE is configured for 4 CC.If PHR triggering of the CC#2 at the t1 moment is caused by the variation of PL, Caused by the PL variation of the RS number k=2 of e.g. PL, then the PHR of CC#2 should include the PHR of k=2.At the t7 moment, CC#4 PHR be also triggered, caused by the PL of the RS number k=1 of e.g. PL variation, then the PHR that the t8 moment sends at least will include The corresponding PHR of RS of the RS number k=1 of the PL of CC#4.

After a PHR trigger event occurs, before reporting PHR, and there are other CC also to trigger PHR, and the PHR Caused by being the variation of PL, then new PHR triggering does not influence the PHR of the CC of other existing PHR triggerings.

After a PHR trigger event occurs, before reporting PHR, and there are other CC also to trigger PHR, and the PHR Caused by being the variation of PL, then new PHR triggering does not influence its PHR to other CC without PHR triggering, such as CC#3.

Alternatively, before reporting PHR, and there are other CC also to trigger PHR after a PHR trigger event occurs, and The PHR is caused by the variation of PL, then new PHR triggering is to other CC without PHR triggering, such as CC#3, according to new PHR triggering moment updates its PHR.

As shown in figure 4, being carved with PHR triggering on CC#4 in t7, CC#2 is not influenced and is triggered in the PHR at t1 moment to CC#2's The calculating parameter of PHR.

About UL grant, the relationship of PDCCH, DCI:

PDCCH is down control channel, wherein including DCI (Downlink Control Information), DCI supports different formats.Such as The demand that DCI format 0-0,0-1,1-0,1-1,2-0,2-1,2-2,2-3 etc. are used to that different scenes to be supported to issue control information.

PDCCH is scrambled by different RNTI, and RNTI may be UE specific, it is also possible to which multicast is directed to one group of UE , it is also possible to broadcast, i.e., for all UE's.

UE, which is configured in specific resource, receives PDCCH, and attempts to descramble with specific RNTI, if descrambled successfully, Then the PDCCH is destined to the UE's.UE may be configured for a variety of RNTI, therefore can attempt to be solved with different RNTI PDCCH, and further parse according to successful RNTI the content of DCI.

It include UL grant information, such as DCI 0-0,0-1 in the DCI of some formats, other formats are then without UL Grant information may include DL grant information, such as DCI1-0,1-1, or not have grant information but other information, If DCI2-2 is the TPC command that grouping is sent.

UL grant information includes the scheduling information to uplink, the i.e. resource information of uplink, it may be possible to is directed to The resource of new transmission, it is also possible to for the resource transmitted again, be briefly referred to as the resource of new biography and for re-transmission Resource.

A BWP of preferred embodiment more than 6 shares TPC command, and multiple k, l share TPC command

In LTE, TPC command is to send power control control command, for sending the closed loop adjustment member of power.TPC command packet It is contained in DCI.It is sent when with mode of unicast, is i.e. when DCI is scrambled using the specific RNTI of UE, only includes the DCI's in each DCI The closed power adjustment amount of target UE；It is sent when with multicast mode, i.e. when DCI is scrambled using the RNTI of UE grouping, each DCI pairs In mono- CC of a UE at most include a TPC command.

In next-generation technology, each CC may be configured or activate more than one BWP.If the BWP quantity of activation is greater than 1, then each DCI should include more than one TPC command for an each CC of UE.Each BWP group shared TPC command, or Person shares closed-loop power control.

It c. include the TPC command of the grouping number of the BWP of activation, the biography being respectively used in each BWP grouping in each CC Defeated power control

D. the TPC command comprising CC grouping number, is respectively used to the power control of the transmission in each CC grouping

The above TPC command number only considers that each DCI carries the TPC command of a closed-loop power control.For example, carrying determination Perhaps l=1 l value is not fixed and can otherwise determine closed-loop power control number l=0.

If the TPC command more than one that a DCI is sent, above-mentioned TPC command quantity will also extend.Including it is following it One:

A) include to the BWP of each activation in each CC the closed-loop power control quantity supported on the BWP TPC command, respectively The power control of the transmission of corresponding closed-loop power control on BWP for each activation

B) TPC command for the closed-loop power control quantity supported on the BWP is included to each BWP grouping in each CC, used respectively In the power control of the transmission of corresponding closed-loop power control in each BWP grouping

C) to the closed-loop power control number supported in grouping of the BWP grouping including the BWP of the activation of each activation in each CC The TPC command of amount is respectively used to the power control of the transmission of corresponding closed-loop power control in each BWP grouping

D) TPC command for the closed-loop power control quantity supported comprising the grouping each CC grouping, is respectively used to each CC points The power control of corresponding transmission in group
