Description

The method and device that power climbing space is arranged

Technical field

Invention relates to communication field, particularly relates to a kind of power climbing space (Power Headroom is called for short PH) and arranges Method and device.

Background technology

At 3GPP LTE (The 3rd Generation Partnership Project Long Term Evolution, third generation partner program Long Term Evolution) in system, uplink power control (Uplink Power Control, may be simply referred to as uplink power control or power control) it is used for controlling uplink physical channel (Uplink Physical Channel) Transmitting power, to compensate path loss and the shadow fading of channel, and suppress presence of intercell interference.Wherein, uplink power control controls Uplink physical channel include Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH), physics Ascending control channel (Physical Uplink Control Channel, PUCCH) and measuring reference signals (Sounding Reference Signal, SRS) etc..LTE uplink power control uses open loop (open loop) to tie mutually with closed loop (closed loop) The control mode closed.

For the subscriber equipment (User Equipment, UE) in LTE system, Physical Uplink Shared Channel PUSCH Transmit power in subframe i is defined as:

P_PUSCH(i)=min{P_CMAX, 10log₁₀(M_PUSCH(i))+P_{O_PUSCH}(j)+α(j)·PL+Δ_TF(i)+f(i)} [dBm]

Wherein: i is natural number, " [] " internal alphabet shows the unit of parameter, P_CMAXIt is that the UE maximum configured that UE is arranged exports Power (the Configured Maximum UE output power), its span is together decided on by multiple parameters, bag Include: the maximum UE power (the maximum UE power) that determined by UE power grade (the UE power class), be Under unified central planning put IE P-Max (maximum configured power), maximum configured output deviation (PCMAX tolerance) and by High-power decline (Maximum Power Reduction, MPR) and extra peak power decline (Additional Maximum Power Reduction, A-MPR) etc.；

M_PUSCHI () is the PUSCH bandwidth sent in subframe i, its value number of Resource Block (Resource Block, RB) Represent；

P_{O_PUSCH}J () is an open loop power control parameter, its value is a community specific (cell specific) amount P_{O_NOMINAL_PUSCH}(j) and UE specific (UE specific) amount P_{O_UE_PUSCH}J the sum of (), is all configured by high level；Wherein, PUSCH transmission under j=0 correspondence semi-continuous scheduling (semi-persistent scheduled) state, j=1 is corresponding dynamically to be adjusted PUSCH transmission under degree (dynamic scheduled) state, the PUSCH transmission of j=2 correspondence accidental access response scheduling；

α is the specific road loss compensation factor in community, high level configure.As j=0 or 1, α (j) ∈ 0,0.4,0.5, 0.6,0.7,0.8,0.9,1}；As j=2, α (j)=1.Being that complete path loss compensates when α=1, α ＜ 1 mends for part path loss Repay；

PL is that the descending path loss measured at UE end and calculate estimates (the downlink pathloss estimate), uses In estimating up path loss；

Δ_TFI () is relevant with the transformat (Transmission Format, TF) of the PUSCH of transmission in subframe i Power bias；

F (i) is that the current power of PUSCH controls adjustment state.According to the configuration of higher level parameters, when for accumulated value power control Time, f (i)=f (i-1)+δ_PUSCH(i-K_PUSCH)；When for absolute value power control, f (i)=δ_PUSCH(i-K_PUSCH).Wherein, δ_PUSCH It is a UE specific Closed-cycle correction value, is also called emissive power control command (TPC command).

The PUSCH that UE estimates according to open loop and closed-loop power control parameter, instruction, the path loss of base station and sends in subframe i The transmitting power of PUSCH that estimates of number of resource blocks be:

P′_PUSCH(i)=10log₁₀(M_PUSCH(i))+P_{O_PUSCH}(j)+α(j)·PL+Δ_TF(i)+f (i) [dBm],

For the thing that the maximum configured output making base station be able to know that at a time certain UE is arranged is scheduled with it Reason up channel PUSCH estimates the allowance launched between power, thus dispatches scheduling of resource and the chain of PUSCH for base station next time Road self adaptation provides foundation, UE need to calculate the power climbing space (Power Headroom, also known as margin of power) of self and Report is to base station.In LTE system, UE power climbing space in subframe i is defined as:

PH (i)=P_CMAX-{10log₁₀(M_PUSCH(i))+P_{O_PUSCH}(j)+α(j)·PL+Δ_TF(i)+f (i) } [dB],

The maximum configured output that i.e. UE power climbing space in subframe i is arranged equal to UE is estimated with UE The difference of the transmitting power of PUSCH.To be quantified in the range of [-23,40] dB by calculated power climbing space, with 1dB Take immediate integer value (quantitative relationship is as shown in table 1) for precision, then passed to high level by physical layer.

Table 1 is quantized value and the mapping relations table of index of power climbing space.As shown in Table 1, media access control layer (Media Access Control Layer, referred to as MAC layer) represents the power climbing space after quantization with 6bits index, 6bits index also referred to as power climbing space.

The report (Power Headroom Report, PHR) of power climbing space triggers (event-by event triggered).When UE has new upstream data to transmit at present sub-frame, and event is had to trigger power headroom reporting, and Base station is that the channel resource of the PUSCH transmission distribution of this UE be enough on load power according to certain priority of logical channels order Rise space MAC layer control unit (Power Headroom MAC Control Element) and mac-layer protocol data cell thereof During sub-head (MAC PDU subheader), UE is empty by the power rise of 6bits by power climbing space MAC layer control unit Between index clothes accuse to base station.

It should be noted that in LTE system, only to sending PUSCH, and PUSCH has new transmitting uplink data Subframe reports power climbing space.If present sub-frame does not has PUSCH to send, or present sub-frame only retransmits PUSCH, though power Rising space report PHR is triggered by event, and UE can not report power climbing space.

LTE-Advanced system (evolution LTE system, it is possible to referred to as lte-a system) is that the next generation of LTE system drills Enter system.Fig. 1 is the schematic diagram of the carrier aggregation of lte-a system in prior art.As it is shown in figure 1, lte-a system uses carrier wave Polymerization (carrier aggregation) technology extension transmission bandwidth, the carrier wave of each polymerization is referred to as one " component carrier " (component carrier)。

In lte-a system, subscriber equipment can send a PUSCH on one-component carrier wave, it is also possible to simultaneously many Multiple PUSCH is sent respectively on individual component carrier.On each component carrier, the scheduling of PUSCH is independent, and power control is also Independent.

Therefore, prior art proposes, and in lte-a system, the calculating of power climbing space is based on component carrier (CC Specific PHR, or claim PHR per CC), i.e. subscriber equipment calculates the power climbing space of each component carrier respectively.

Prior art is also, it has been proposed that the power climbing space of one-component carrier wave can report on another component carrier Base station, the power climbing space MAC layer control unit i.e. including one-component carrier power rising space information can be passed through The PUSCH sent on another component carrier reports base station.

This delay just reported for reducing power climbing space provides possibility.Such as to a certain component carrier, on power Rise space report to be triggered by event, and present sub-frame does not has new upstream data to send on this component carrier, if one point The power climbing space of loading gage ripple is limited on this component carrier and reports, then present sub-frame subscriber equipment can not report power rise Space；And if the power climbing space of one-component carrier wave can report on another component carrier, and assume present sub-frame Subscriber equipment has new transmitting uplink data on another component carrier, then present sub-frame subscriber equipment can be at another component The power climbing space being triggered is reported on carrier wave.

Now, although subscriber equipment does not has PUSCH to send on the component carrier that the power climbing space that is triggered reports, or Only having the PUSCH retransmitted to send, subscriber equipment still needs to calculate the power climbing space of this component carrier current.

Prior art defines two kinds of power climbing spaces based on component carrier calculated on subframe i component carrier wave k, It is respectively as follows:

First kind power climbing space (power headroom type 1)

${\mathrm{PH}}_{\mathrm{type}1}(i,k)=P_{\mathrm{CMAX}}\left(k\right)-P_{\mathrm{PUSCH}}\left(i\right)=10{\log }_{10}\left(\frac{{10}^{P_{\mathrm{CMAX}}\left(k\right)/10}}{{10}^{P_{\mathrm{PUSCH}}(i,k)/10}}\right)\left[\mathrm{dB}\right],$

Equations of The Second Kind power climbing space (power headroom type 2)

${\mathrm{PH}}_{\mathrm{type}2}(i,k)={10\log }_{10}\left(\frac{{10}^{P_{\mathrm{CMAX}}\left(k\right)/10}-{10}^{P_{\mathrm{PUCCH}}(i,k)/10}}{{10}^{P_{\mathrm{PUSCH}}(i,k)/10}}\right)\left[\mathrm{dB}\right],$

Wherein, P_CMAXK () [dBm] is the maximum transmission power (a CC-specificmax power) of component carrier k, P_PUSCH(i, k) [dBm] is that subscriber equipment estimates that the PUSCH's sent on subframe i component carrier wave k estimates transmitting power, P_PUCCH (i, k) [dBm] is that subscriber equipment estimates that the PUCCH's sent on subframe i component carrier wave k estimates transmitting power, and k is that component carries The numbering of ripple.

When having PUSCH to send on subframe i component carrier wave k, the transmitting power of estimating of PUSCH is

P_PUSCH(i, k)=10log₁₀M_PUSCH(i, k))+P_{O_PUSCH}(j, k)+α (j, k) PL (k)+Δ_TF(i, k)+f (i, K) [dBm],

Wherein, M_PUSCH(i is k) to estimate the bandwidth of the PUSCH of transmission, its value Resource Block on subframe i component carrier wave k The number of RB represents；

P_{O_PUSCH}(j is k) open loop power control parameter based on component carrier k, high level configures, wherein, j=0 correspondence is partly held PUSCH transmission under continuous scheduling (semi-persistent scheduled) state, j=1 correspondence dynamic dispatching (dynamic Scheduled) PUSCH transmission under state, the PUSCH transmission of j=2 correspondence accidental access response scheduling；

(j is k) road loss compensation factor based on component carrier k, high level configures α.As α, (j is complete road when k)=1 Damaging and compensate, (j, k) ＜ 1 compensates α for part path loss；

PL (k) is that the descending path loss that subscriber equipment end is measured and calculated is estimated, for estimating the upper walking along the street of component carrier k Damage；

Δ_TF(i k) is and estimates that the power that the transformat of the PUSCH of transmission is relevant on subframe i component carrier wave k is inclined Put；

(i is k) that the current power of PUSCH on component carrier k controls adjustment state to f.According to the configuration of higher level parameters, When for accumulated value power control, f (i)=f (i-1)+δ_PUSCH(i-K_PUSCH)；When for absolute value power control, f (i)=δ_PUSCH(i- K_PUSCH).Wherein, δ_PUSCHIt is a UE specific Closed-cycle correction value, is also called emissive power control command (TPC command).

And when not having PUSCH to send on subframe i component carrier wave k, how to calculate PUSCH estimates transmitting power, and then How to calculate the power climbing space at subframe i component carrier wave k, become a problem demanding prompt solution.

It should be noted that Equations of The Second Kind power climbing space only can send definition on the component carrier of PUCCH.Existing Technology proposes, the lte-a system to carrier aggregation, and subscriber equipment is only at a subscriber equipment specific (UE-specific) point Sending PUCCH on loading gage ripple, described component carrier is referred to as principal component carrier wave (Primary Component Carrier, PCC). Then Equations of The Second Kind power climbing space is merely defined on described subscriber equipment specific principal component carrier wave PCC.

It addition, prior art is also, it has been proposed that when calculating power climbing space based on component carrier, need to count back-off (power backoff).Back-off is relevant with factors, includes but not limited to: working band, system bandwidth, modulation order Whether number, transmission bandwidth position, transmission bandwidth configuration etc., also use discontinuous resource distribution mode with PUSCH, PUSCH and PUCCH sends relevant the most simultaneously.The scope of back-off can decline (Maximum Power by peak power Reduction, MPR) limit.When subscriber equipment sends upward signal, according to the relevant configuration of upward signal, transmitter merit The configuration of rate amplifier (Power Amplifier, AP), and the decline of the peak power under corresponding scene of standard regulation, Determine the back-off of maximum transmission power.The maximum transmission power that then subscriber equipment is arranged on component carrier is less than base station The maximum transmission power of configuration on component carrier.

During realizing the present invention, invention recognizes that prior art has following defects that if present sub-frame is at certain On individual component carrier, subscriber equipment does not has PUSCH to send, or present sub-frame subscriber equipment on certain component carrier only has and retransmits When PUSCH sends, subscriber equipment can not calculate and report power climbing space.
