Description

The acquisition methods of power headroom and macro base station

Technical field

The present invention relates to the communications field, be specifically related to a kind of acquisition methods and Hong Ji of power headroomStand.

Background technology

Dual link network is the study hotspot of the current wireless communication technology, and the network architecture is as Fig. 1 instituteShow. For the overlapping covering in macrocell and small-cell and use identical/different frequency, or only depositCover in small-cell, the nonideal scene of return link between community, has introduced dual link skillArt. Dual link refers to, and user provides wireless by the undesirable network node of multiple return linksResource. Namely user simultaneously with macro base station (be called for short: MeNB) and micro-base station (abbreviation:SeNB) exist and eat dishes without rice or wine to connect, this means that MeNB and SeNB can be simultaneously for user carryFor service. UE) and MeNB due to subscriber equipment, (UnifiedEquipment is called for short:Also have SeNB to have connection, UE moves and enters or leave in macrocell inside simultaneously, can not carry out handoff procedure when the Microcell, and just adopt and be similar to resource reconfigurationProcess is come for UE configuration or is discharged small-cell resource, not only can improve the mobility of heterogeneous networkPerformance, can reduce the signaling load of whole system in addition.

(LongTermEvolution is called for short: LTE) the existing mobile 4G network of releasingIn system, UE need to report to eNB the power headroom reporting (PHR) (PowerHeadroom of oneselfReporting, is called for short: PHR), for eNB, UE is carried out to scheduling of resource and power control.PHR is defined as UE nominal maximum transmission power and current Uplink Shared Channel (UplinkSharedChannel, is called for short: the UL-SCH) difference between through-put power estimated value.

ENB can be a up maximum transmission power P-Max of UE configuration by broadcast,Afterwards UE according to P-Max, self power grade and some other because of usually determine oneselfNominal maximum transmission power.

By radio resource control, (RadioResourceControl is called for short: RRC) eNB" phr-Config " IE in " MAC-MainConfig " IE in signaling is UE configurationPHR relevant parameter, for controlling the triggering of PHR, these parameters comprise:periodicPHR-Timer,prohibitPHR-Timer,dl-PathlossChange。

PHR is that (MACControlElement is called for short MAC by MAC Control ElementCE) form reports, if UE has triggered PHR and met reporting of PHRCondition, UE produces a PHRMACCE and is reported eNB.

In LTE single-carrier system, the form of PHRMACCE as shown in Figure 2, wherein" R " is reserved bit, and " PH " takies 6 bits.

In LTE multicarrier system, introduce expansion PHRMACCE in order to support carrier wavePolymerization technique. If network configuration physical uplink control channel (PhysicalUplinkPUCCH) and Physical Uplink Shared Channel (PhysicalUplink ControlChannel, is called for short:SharedChannel, is called for short: PUSCH) simultaneously when reporting information, UE also needs to reportThe pH value of the Type2 type of PCell. In expansion PHRMACCE, having defined SCell refers toShow that territory is in order to indicate the PH territory that SCell is corresponding. The form of expansion PHRMACCE is as Fig. 3Shown in, wherein " R " is reserved bit, the SCell that " Ci " instruction index value is SCellIndexiPH territory whether occur; " PH " takies 6 bit; PCMAX, C indicates corresponding meritRate value.

In LTE system, each MACCE can a corresponding MAC head, at it(LogicalChannelIdentity is called for short: LCID) Logic Channel Identifier that middle use is differentRepresent different MACCE types, in MAC corresponding to PHRMACCE headLCID is " 11010 ", the LCID of the MAC head that expansion PHRMACCE is correspondingFor " 11001 ". MAC form corresponding to MACCE as shown in Figure 4.

At present for the power headroom reporting in dual link technology just like drawing a conclusion: dual link UEConfigurable total Serving cell quantity mostly is 5 most; Dual link user's auxiliary serving cell indexSCellIndex configures based on UE; If due to Pathloss change, P-MPR change andSCell activates the PHR triggering and reports, and reports two MAC entities; If the cycleReport with the PHR that reshuffles triggering, only report corresponding MAC entity; Dual linkPHRMACCE form of middle use; In PHR, comprise the PH letter of all activated communityBreath; The LCID that working hypothesis is new is used for the PHRMACCE of dual link; PSCell addsTime the PHR that sets out report; The PH of the Type2 type that comprises PSCell is at the Type2 of PCellAfter the PH byte of type, and the PHs of all Type1 types before; In additionDual link always reports the PH of the Type2 type of PCell and PSCell.

It is all sharp that current 3gpp has specified that dual link is used a PHRMACCE form to reportThe PH information of community alive, but the concrete PHRMACCE format details adopting does not also haveDetermine eventually. Suppose to introduce new LCID and be used to indicate the PHRMACCE of dual link, but go backDo not have finally to determine and must introduce new LCID. Introduce new LCID and be used to indicate PHRThe type of MACCE be expansion or dual link, main purpose be exactly for allow MeNB andSeNB can be easy to identify whether the PHRMACCE that UE reports is to report based on dual link. Consider the in short supply of reserved LCID resource, MeNB and SeNB want to identify on UEWhether the PHRMACCE of report is to report and be still urgently to be resolved hurrily asking based on dual linkTopic.

Detailed description of the invention

Below in conjunction with accompanying drawing, the detailed description of the invention of invention is further described. Below implementExample is only for technical scheme of the present invention is more clearly described, and can not limit this with thisBright protection domain.

3GPP discusses and determines at present, adopts a PHRMACCE form in dual linkReport the PH information of all Serving cells. PSCell in SeNB need to configure PUCCHResource. In carrier aggregation scene, if network configuration PUCCH and PUSCH go up simultaneouslyReport, UE need to report the pH value of the Type2 type of PCell. Equally, in dual linkIn scene, if SeNB and MeNB likely configure PUCCH and PUSCH whileReport, need so UE to report the pH value of the Type2 type of PCell and PSCell. AsFruit MeNB and SeNB do not obtain the other side and whether have configured PUCCH and PUSCH to UEReport simultaneously, cannot in same PHRMACCE, identify whether comprise the other sideThe pH value of the Type2 type of eNB, causes data receiver mistake. For this problem, 3GPPRAN1 working group discusses and reaches a conclusion: no matter dual link network SeNB and MeNB areNoly configured PUCCH and PUSCH reports simultaneously, in the PHRMACCE reporting alwaysThe Type2PH relevant information that comprises PCell and PSCell.

As shown in Figure 5A, in dual link network, need to set up MCG and SCG, MCGRefer to one group of Serving cell of associated MeNB, by PCell and optional one or more SCellComposition; SCG refers to one group of Serving cell of associated SeNB, by PSCell and optional oneIndividual or multiple SCell compositions.

511, UE sets up RRC with macro base station MeNB and is connected, and then UE reports micro-base stationSeNB measurement result, the measurement report that MeNB can be based on receiving or professional qualification orBearer types, determines whether allowing a SeNB provide the extra resource of UE to transmit.

In dual link network process of establishing, identify the Serving cell of interpolation with SCellIndex,SCellIndex distributes based on UE, and MeNB and SeNB distribute from common poolSCellIndex, MeNB is in the time that the SeNB to satisfying condition sends community interpolation request messageThe Serving cell of controlling for SeNB distributes SCellIndex. SeNB decides PSCell, PCellSCellIndex value to mark PSCell does not retrain, can get between (1,7) arbitrarilyValue. As PCell, PSCell can not be deactivated, and in SCG, only has PSCell energyEnough transmit PUCCH.

512, SeNB sends the resource distribution of SCG community to MeNB, UE receive fromThe reconfiguration message that MeNB sends.

UE report in MCG sharp owing to likely can trigger UE before connecting with SeNBThe power headroom of Serving cell alive, has issued the weight that comprises SCG configuration information to UE at MeNBAfter configuration messages, UE need to apply the configuration information of SCG resource.

513, judge whether the configuration of SCG local resource completes.

Concrete, after UE successful Application SCG resource distribution, reshuffle to MeNB feedbackBe successfully completed message, dual link is successfully established, and the PSCell simultaneously adding is initially located in activation shapeState.

514,, when dual link is successfully established, meet PHR report condition and adopt DCPHRMACCE form reports.

515,, when dual link is not set up, meet PHR report condition and adopt expansion PHRMACCE form reports. How the flow process reporting according to PHR is below to resolving PHRMACCEObtaining power headroom is introduced.

Otherwise, if T is set to " 0 ", adopt expansion PHRMACCE form to report,Specific as follows:

In the time that the value of the second bit in described MAC head is not 1, described all Serving cellsPower margin information is:

As shown in Figure 3, the master of second power headroom value-> macro base station of the main plot of macro base station is littleFirst power headroom value-> macro base station of the main plot of maximum transmission power value-> macro base station in districtFirst of maximum transmission power value-> UE of main plot activate more than the first power of auxiliary communityThe n that first of value-> UE activates maximum transmission power value-> UE of auxiliary community swashsThe maximum transmitted merit of n the auxiliary community of activation of first power headroom value-> UE of Huo Fu communityRate value.

In another enforceable mode, refer to by the index that judges main plot, described micro-base stationWhether the value of showing territory is 1 to obtain the power margin information of described all Serving cells.

As shown in Figure 5 D, adopt the PSCell in expansion PHRMACCE correspondingWhether SCellIndex instruction territory Ci distinguishes the PHRMACCE reporting based on dual link. ShouldMethod comprises the steps:

541, MeNB sends after the reconfiguration message of dual link foundation, receives what UE sentPHRMACCE。

542, judgement receive UE send PHRMACCE in MACSDU in micro-Whether the SCellIndex instruction territory Ci that main plot, base station PSCell is corresponding is 1.

543, when being 1, according to DCPHRMACCE format analysis.

544, when not being 1, according to expansion PHRMACCE format analysis.

In dual link network, the span of SCellIndex is (1-7), same eNB5 Serving cells of configuration at most, a PCell and 4 SCell. In dual link network,For MeNB and the maximum configurable Serving cells of SeNB total of dual link user service are 5Individual, a PCell, a PSCell and 3 SCell.

In the expansion PHRMACCE that carrier aggregation is introduced, report all activated Serving cellPower margin information, it indicates with SCell instruction territory Ci the PHRMACCE reportingIn whether comprised the PH information of the SCell that index value is SCellIndexi. Dual link sceneIn, still adopt SCellIndex to identify PSCell, SCellIndex distributes based on UE.It is SCG service that MeNB sends when request message is added in community at the SeNB to satisfying conditionCell allocation SCellIndex, SeNB decides PSCell.

The present invention utilizes existing mark PowerHeadroomMACControlElement'sLCID, and corresponding mark PSCell in existing expansion PHRMACCE form bitmap territoryInstruction territory Ci identify and report whether PH information is based on dual link setting.

As shown in Figure 8 A, suppose that network is dual link user configuration 5 Serving cells altogether,PCell cell index is defaulted as 0, configures in addition two SCell of MCG, its SCellIndexValue is respectively 2,5; The SCellIndex value of two Serving cells of configuration SCG is respectively3,4, wherein the SCellIndex value of PSCell is 3. Due to after dual link is successfully established,The PSCell adding is initially located in state of activation, and is never deactivated. So according to expansionThe design principle of PHRMACCE, if the Serving cell of the SCellIndex=i of Serving cellFor state of activation, the instruction territory Ci in expansion PHRMACCE is set to 1, andReport the PH information of this Serving cell; If the service of the SCellIndex=i of Serving cell is littleDistrict is deactivation status, and the instruction territory Ci in expansion PHRMACCE is set to 0,Do not report the PH information of this community. In this embodiment, as shown in Figure 8 B, in dual linkBefore being successfully established, may triggering UE and report the PH information that activates Serving cell in MCG,Because the PSCell of SCG does not belong to state of activation, the SCellIndex=3 of corresponding PSCellCi territory should be set to 0, if MeNB receives the PHR that UE reports, judge that this territory is0 that can judge that UE reports is the PH that does not comprise SCG community in PHRMACCEInformation, as shown in Figure 3; Otherwise, as shown in Figure 8 C, report if MeNB receives UEPHR, judge that this territory is 1 can determine UE application dual link configuration successful, PSCell, in state of activation, in the PHRMACCE that UE reports, comprise LiaoSCG communityPH information, as shown in Fig. 7 A and 7B.
