Description
Technical field
The present invention relates to the communications field, in particular to a kind of power headroom reporting (PHR) triggering method and device.
Background technology
At present, wireless communication system uses electromagnetic wave and wireless telecommunications user equipment fixing or that move (for example, radio telephone or all can be called as subscriber equipment with notebook, the apparatus such as computer of wireless communication card) to communicate.In general, when carrying out radio communication, subscriber equipment (User Equipment is called for short UE) is positioned within the wireless coverage of system, and communicates through radio communication channel and system.Concrete, radio communication channel is divided into a plurality of carrier frequencies with wave frequency, and a carrier frequency or a plurality of carrier frequency can constitute a wireless service areas.Subscriber equipment can be got in touch through other equipment in one or more carrier wave homologous rays (for example controlling network element or other subscriber equipmenies).
The control network element of wireless communication system can be according to other equipment of communication protocol/technique control of system's agreement.The control network element comprises control station and network.Control station includes but not limited to base station (Base Station; Abbreviation BS), relay station (Relay Station; Be called for short RS) and subscriber equipment, when subscriber equipment was used as control station, this subscriber equipment can be the interim control station of in subscriber equipment, selecting according to pre-defined rule of conduct.Communication protocol/technique includes but not limited to GSM (Global System for MobileCommunications; Global system for mobile communications), CDMA (Code Division Multiple Access; Code division multiple access), EDGE (Enhanced Data Rate for GSM Evolution; The enhanced data rates for gsm evolution technology), CDMA2000, TD-SCDMA (Time Division-Synchronous Code Division Multiple Access; TD SDMA), HSPA (High Speed Packet Access; The high-speed packet access), WCDMA (Wideband Code Division MultipleAccess, WCDMA), EVDO (Evolution Data Only, only evolution data), HSOPA (High Speed OFDMPacket Access; The access of high speed orthogonal frequency division multiplexed packet), WiMAX (World Interoperability for MicrowaveAccess; Micro-wave access global inter communication), LTE (Long Term Evolution, Long Term Evolution) and LTE-A (LTE-Advanced, Long Term Evolution-senior).
Wireless communication system can utilize the wireless channel of appointment in certain geographic range, wireless coverage to be provided through the base station, and this geographic range is called the sub-district.Usually, in theory, the base station should be positioned at the central authorities of sub-district.According to the size of base station range, the base station can be divided into grand (Macro) base station, little (Pico) base station and slight (Femto) base station.In the LTE/LTE-A system, the base station is also referred to as and strengthens B node (eNodeB), and femto base station is also referred to as Home eNodeB or family strengthens B node (HomeeNodeB is called for short HeNodeB).
In addition, cover or the expansion capacity in order to expand, one or more relay stations can be placed between subscriber equipment and the base station.For subscriber equipment, relay station just is equivalent to a base station.Perhaps; In the extremely many networks of subscriber equipment quantity; Subscriber equipment also can be formed adhoc network (perhaps being called cluster) voluntarily, and as interim control station, assistance system is managed by certain subscriber equipment in the adhoc network; Interim control station can be accepted original control station control, management subordinate's subscriber equipment.
The main process of the uplink power control of LTE is:
(1) UE receives TPC (transmitting power control, power control command);
(2) UE (subscriber equipment) carries out the measurement of downlink wireless channel pilot reception power, calculating path loss Pathloss, and UE is with calculation of parameter transmitting power P such as Pathloss, Uplink Shared Channel bandwidth, transport block format and TPC; If subscriber equipment has triggered PHR (power headroom report, power headroom reporting (PHR)), and satisfied transmission condition, UE also need send PHR on Uplink Shared Channel so.
(3) after eNodeB (evolved base station) received Physical Uplink Shared Channel and/or PHR, the Physical Downlink Control Channel through DCI Format 0/3/3A sent TPC to UE; Return execution in step (1).
UE adopts dynamic resource distribution mode in the system; And adopt adaptive chnnel coding modulation system (adaptivemodulation and coding; AMC), LTE UE uplink transmission power and resource allocation, code modulation mode are relevant, and therefore independent power control mode also is not enough to accomplish the power control task of LTE UE; The PHR that sends to eNodeB through UE provides foundation as the resource budget information of PUSCH for eNodeB carries out uplink resource allocation.If PHR reflects UE bigger power headroom is arranged, eNodeB can distribute more wireless resource block to give UE so; Do not had power headroom if PHR reflects UE, perhaps do not had more power headroom, eNodeB can only distribute less wireless resource block or low-order-modulated to order to UE so.
UE is lower than eNodeB to the TPC of UE transmission frequency to the PHR transmission frequency of eNodeB in the LTE system.The transmission of PHR needs two steps: at first be to trigger, report then.UE when cycle PHR timer expires or path loss changes greatly or during the PHR configuration/reconfiguration triggering PHR report, after UE had obtained enough to be used for the PUSCH resource of PHR, UE reported PHR to eNodeB.
PHR is calculated as PH (i)=P
CMAX-P
Ue, tx, P
CMAXBe UE configuration maximum transmission power (configuredmaximum output power); PCMAX_L≤PCMAX≤PCMAX_H; The span of PCMAX mainly contains 2 kinds of limited resource: 1) be subject to the control of eNodeB; Such as the little covering scene in little base station, eNodeB can control the maximum transmission power of UE, to reduce the interference of UE to the adjacent area; 2) the useless out-of-band radiation of UE (Out of band emission) is as in order to satisfy SEM (Spectrum emission mask, spectrum emission mask (SEM)) and ACLR (Adjacent Channel LeakageRatio; The adjacent band reveal than) etc. requirement; UE can design responsible filter, is used for reducing out-of-band radiation, and perhaps UE reduces maximum transmission power; The former can increase the cost of UE, and the latter has reduced the uplink capacity of UE.Because the reduction transmitting power (be also referred to as back-off, power reduce, method PR) is simply effective, and a large amount of UE can adopt this method to reach the requirement of out-of-band radiation when realizing.But, do not allow the unconfined reduction power of UE, to such an extent as to can not carry out basic uplink service in order to guarantee the up transmitting capacity of UE; MPR (the Maximum Power Reduction that definition allows in the agreement; Maximum power rollback value), because the size of out-of-band radiation is followed the modulation configuration of sending data, and the bandwidth that takies all has relation; Like LTE in agreement 36.101; Be provided with different MPR by different transmission bandwidth with the modulation pattern, as shown in table 1 below: each UE can be provided with actual PR value by the realization of self, as long as satisfy PR≤MPR.
Table 1
So after considering back-off, UE deducts actual back-off value on the basis of specified transmitting power Ppowerclass, and after needing to consider the maximum transmission power of above-mentioned network permission, the minimum value of getting among both is actual PCMAX.P
Ue, txBe the up theoretical transmitting power of UE.In LTE, only consider the transmitting power of PUSCH among the PHR, so P
Ue, tx=P
Ue, pusch, P
Ue, puschIn LTE, be the transmitting power of PUSCH, be defined as P
Ue, pusch=10log
10(M
PUSCH(i))+P
O_PUSCH(t)+α (t) PL+ Δ
TF(i)+and f (i), M wherein
PUSCH(i) be MCS (Modulation and Coding Scheme, modulating-coding form) configuration decision, the P of the transmission bandwidth of PUSCH by scheduling
O_PUSCH(t) be that part path loss offset, t are that semi-static variable, PL are path loss, Δ for open loop power control adjusted value, α (t)
TF(i) be that transformat offset, f (i) are the closed-loop power control adjusted value, promptly the transmitting power of PUSCH is with the bandwidth that takies resource of PUSCH, and the path loss between UE and base station and the configuration of open loop power control and closed-loop power control are relevant.So the PHR computing formula is PH (i)=P
CMAX-{ 10log
10(M
PUSCH(i))+P
O_PUSCH(t)+α (t) PL+ Δ
TF(i)+f (i) }.
PHR's is unit with dB, and power is unit with dBm in the formula.
In LTE, the triggering that PHR reports (trigger) mainly contains following three kinds of situation:
1) PHR forbids that timer (prohibitPHR-Timer) is overtime, and the variable quantity that reports with respect to last PHR of path loss is during greater than predetermined threshold dl-PathlossChange (unit is a decibel dB);
2) PHR cycle timer (periodicPHR-Timer) is overtime;
3) configuration of PHR functional entity or reshuffle;
After PHR was triggered, when UE had the uplink scheduling resource to hold PHR, UE sent to eNB with PHR.
Along with development of Communication Technique, because the P that the subscriber equipment power management causes
CMAXChange and also need consider in the calculating of PHR.Concrete; The requirement source of this power adjustment can be that regional absorptivity requires (regional SAR; Power need be reduced or the transmitter power of work before dual transmitter when work need be adjusted etc. when SpecificAbsorption Rate), SAR requirement scene comprised subscriber equipment near human body.
Because the subscriber equipment power management causes P
CMAXChange, corresponding, might cause PH to change, under this new situation, how eNodeB and subscriber equipment carry out the assessment of power headroom, and how subscriber equipment carries out PHR reports, and all is the problem of needing solution badly.
For above-mentioned existing problem; There is technology to think at present; A trigger condition should be set separately; PHR forbids that timer (prohibitPHR-Timer) is overtime, and the variable quantity that reports with respect to last PHR of subscriber equipment power management value just needs to trigger PHR during greater than dl-PathlossChange.
The problem of doing like this is: owing to report the thresholding of variable quantity the same with existing path loss variable quantity thresholding; But in fact the variation of power management value changes irrelevant with path loss; Therefore the PHR that triggers is easy to cause and makes a false report or fail to report, thereby causes the wasting of resources or the misjudgment in the power adjustment.
In addition; If too frequent, may cause relevant PHR to report too much, because the adjustment of PHR needs the time for the variation of the power variation in the SAR scene; Too frequent PHR not only can not reach the purpose of rapid power adjustment, and can waste the resource of the expense that is used for the power adjustment.
