Description
Technical field
The present invention relates to the senior long term evolution technology of mobile communication system, more particularly, to carrier aggregation scene
The method and device of the specific peak power in lower reporting subdistrict.
Background technology
Long Term Evolution (long term evolution, abbreviation LTE) is third generation partner program (The 3rd
Generation Partnership Project, abbreviation 3GPP) a kind of advanced broadband wireless developed connects
Enter technology, it would be preferable to support the single carrier bandwidth of highest 20M, reach 50M bps upstream rate and
The downstream rate of 100Mbps, and there is low time delay, have been provided with the feature of forth generation mobile communication,
It is a kind of technology of beyond 3G (Beyond 3G).
On LTE standard, 3GPP has developed senior long term evolution (long term evolution
Advanced, abbreviation LTE-A), develop carrier aggregation, the multiple-input and multiple-output (Multiple of higher order
Input Multiple Output, abbreviation MIMO), relaying, multi-point cooperative processes (comp) etc. and is
Row technology, to meet the senior international mobile logical of International Telecommunication Union's Radiocommunication Sector (ITU-R)
The demand of the forth generation mobile communication system that letter (IMT-ADVANCED) defines, such as 500Mbps
Upstream rate, the downstream rate of 1Gbps.
Carrier aggregation (CA) is by collecting positioned at the frequency range of same frequency band (band) or different band
Get up to support higher handling capacity (throughput), under the REL-10 version of carrier aggregation, no
Same carrier wave is all the REL-8/REL-9 of compatible LTE, is the cell with complete function.Its
In the cell that is located of carrier wave be referred to as main plot (Pcell), other referred to as from cell (Scell).Pcell
It is different from Scell, Pcell is responsible for setting up wireless heterogeneous networks (RRC) connection, responsible security parameter, bears
The reception of duty beep-page message, the renewal of responsible system information, it is responsible for dispatching the carrier wave of other cells, be responsible for
The transmission of uplink feedback, etc. special function；The function of Scell is more single, can regard auxiliary as
Pcell completes the band resource of communication task, but also has certain independence, dispatches letter including individual reception
Order, independently carries out Power Control etc..
Due to the particularity of Pcell, it is in wireless heterogeneous networks-connected state (RRC-connected) in UE
Under state, Pcell is activation (activated) forever, i.e. no matter UE and eNB, can and
When using it, and Scell is as assisted cell, within some time periods, does not have downstream transmission to occur,
Within these time periods, Scell is in nonactivated (deactivated) state.Due to LTE/LTE-A
The running time-frequency resource that UE uses is all eNB scheduling, and therefore eNB needs the information obtaining UE carrying out
Correct uplink time/frequency source scheduling, meanwhile, the information that eNB is also required to UE is correctly up to carry out
Power Control, to make UE reach target service quality (QoS), and to reduce to a certain extent
The problem of interference between the co-frequency cell of LTE/LTE-A, the information of UE includes uplink detection signal
(sounding reference signal, abbreviation SRS), and PHR constant power balance information etc., front
Person reflects the channel quality of up-link carrier, and the latter reflects the power headroom of up-link carrier, and eNB can basis
Channel quality comes the time frequency block position of selection scheduling, according to power headroom, can carry out the time-frequency of selection scheduling
Number of blocks, selects modulation format etc..
In REL-8/REL-9 specification, user equipment triggers power headroom reporting PHR, and
Meet transmission condition, then UE needs to send PHR MAC CE, the transmission flow of PHR MAC CE
As shown in Figure 1.In REL-10 specification, if Scell is under deactivated state, UE is not
Need to report PHR for this Scell.Therefore, the trigger event of user equipment includes REL-8/REL-9's
Trigger event and activate event, if that is, UE is when cycle PHR, intervalometer expired, or such as
Fruit component carrier path loss changes greatly, or during PHR configuration/reconfiguration, triggering PHR reports, and should
When Scell is activated, PHR will be triggered, and after UE obtains enough ascending resources, PHR will be by
Send.
Due to due to carrier aggregation, and each Scell uses independent power control process, and each Scell will
Report PH respectively, the UE of carrier aggregation is by using new PHR form；The UL of the UE of carrier aggregation
PCC for Physical Uplink Control Channel (physical uplink control channel, abbreviation PUCCH) and
The transmission of Physical Uplink Shared Channel (Physical uplink shared channel, abbreviation PUSCH) has two
Plant possible pattern：(1) mode pattern 1：PUCCH and PUSCH timesharing sends, same to REL-8/REL-9
Identical.(2) mode pattern 2：PUCCH and PUSCH sends simultaneously.
For pattern 1, when PHR sends, no matter UL PCC and UL SCC only needs to report Type1
PHR.Type1 PHR is defined as the transmit power of the general power removing PUSCH channel of UL PCC,
Such as：
Type1 PHR：PH1=Pcmaxc-PpuschFormula (formula) 1
For pattern 2, when PHR sends, it is only necessary to send Type1 PHR for UL SCC；
For UL PCC, UE needs to report Type1 PHR and Type2 PHR.Type2 PHR is fixed
The general power for UL PCC for the justice removes the transmit power of PUSCH channel and the transmission of PUCCH channel
Power, such as：
Type2 PHR:PH2=Pcmaxc-Ppucch-Ppuschformula2
Wherein, PcmaxcIt is the peak power output of UL PCC, PpucchPUCCH for UL PCC sends out
Send power, PpuschPUSCH transmit power for UL PCC.
When PHR sends, the Scell of activation does not have up transmission, then UE will send for this Scell
Virtual PHR, this virual PHR use the PUSCH form of reference format.If Pcell
On there is no up transmission, then UE will be Pcell send virtual type1 PHR, i.e. this type1 PHR
Using the PUSCH form of reference format, if PUCCH is not had on Pcell, then need
Send virutal type2 PHR, this type2PHR by the PUCCH format using reference format,
Both parameter formats have all been defined, and may be referred to 3GPP 36.321 series standard.
P in formula1 and formula2cmaxcIt is the specific peak power of cell, and the RF of UE is special
Property specification, and the peak power that cell specifies is all relevant.Wherein, UE not can exceed that cell regulation
Peak power.The RF characteristic of UE include peak power decline (Maximum Power Reduction,
Abbreviation MPR) and the decline of extra peak power (Addtitional-Maximum Power Reduction,
Abbreviation A-MPR) constant power constraints.MPR and A-MPR etc. is as the difference dispatched and occurs
Change, leads to PcmaxcAlso can change, UE needs PcmaxcNotify to eNB, so that eNB energy
Enough know the power situation of UE, to be more accurately scheduling.But how to report carrier aggregation field
The carrier wave peak power of scape then there is no solution.
