Description
Technical field
The present invention relates to the communications field, be specifically related to a kind of report method of power headroom and a kind of macro base station.
Background technology
Dual link network is the study hotspot of Current wireless communication technology, and the network architecture as shown in Figure 1.Cover for macrocell with small-cell overlap and use identical/different frequency, or only there is small-cell covering, the nonideal scene of the return link between community, introduces dual link technology.Dual link refers to user and provides Radio Resource by the network node that multiple return link is undesirable.Namely exist with macro base station (being called for short: MeNB) and micro-base station (being called for short: SeNB) while of user and eat dishes without rice or wine to be connected, this means that MeNB and SeNB can simultaneously for user provides service.Due to subscriber equipment (UnifiedEquipment, be called for short: UE) and MeNB also have SeNB to there is connection simultaneously, when UE carries out moving in macrocell inside and enters or leave a Microcell, handoff procedure can not be carried out, and just employing is similar to resource reconfiguration process and comes for UE configuration or release small-cell resource, the mobility performance of heterogeneous network can not only be improved, the signalling loads of whole system can be reduced in addition.
The existing mobile 4G network (LongTermEvolution released, be called for short: LTE) in system, UE needs to report oneself power headroom reporting (PHR) to eNB, and (PowerHeadroomReporting, is called for short: PHR), carries out scheduling of resource and power control for eNB to UE.PHR is defined as UE nominal maximum transmission power and current Uplink Shared Channel (UplinkSharedChannel, abbreviation: difference UL-SCH) between through-put power estimated value.
ENB can be that UE configures a up maximum transmission power P-Max by broadcast, and UE is according to P-Max, the power grade and some other because usually determining the nominal maximum transmission power of oneself of self afterwards.
ENB is by radio resource control (RadioResourceControl, be called for short: " phr-Config " IE in " MAC-MainConfig " IE RRC) in signaling is that UE configures PHR relevant parameter, for the triggering of control PHR, these parameters comprise: periodicPHR-Timer, prohibitPHR-Timer, dl-PathlossChange.
PHR is undertaken reporting by the form of MAC Control Element (MACControlElement is called for short MACCE), if UE triggers PHR and meet the report condition of PHR, then UE produces a PHRMACCE and reported eNB.
In LTE single-carrier system, as shown in Figure 2, wherein " R " is reserved bit to the form of PHRMACCE, and " PH " takies 6 bits.
In LTE multicarrier system, introduce expansion PHRMACCE in order to support carrier aggregation technology.If network configuration physical uplink control channel (PhysicalUplinkControlChannel, PUCCH) and Physical Uplink Shared Channel (PhysicalUplinkSharedChannel be called for short:, be called for short: the while of PUSCH) during reporting information, UE also needs the pH value of the Type2 type reporting PCell.The PH territory of SCell instructions field in order to indicate SCell corresponding is defined in expansion PHRMACCE.As shown in Figure 3, wherein " R " is reserved bit to the form of expansion PHRMACCE, and " Ci " indicates index value to be whether the PH territory of the SCell of SCellIndexi occurs; " PH " takies 6 bit; PCMAX, C indicate corresponding performance number.
In LTE system, each MACCE can a corresponding MAC head, wherein with different Logic Channel Identifier (LogicalChannelIdentity, be called for short: LCID) represent different MACCE types, LCID in the MAC head that PHRMACCE is corresponding is " 11010 ", and the LCID of the MAC head that expansion PHRMACCE is corresponding is " 11001 ".MAC head 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: the configurable total Serving cell quantity of dual link UE mostly is 5 most; The auxiliary serving cell index SCellIndex of dual link user configures based on UE; If due to Pathloss change, the PHR that P-MPR changes and SCell activation triggers reports, then report two MAC entity; If the cycle reports with the PHR reshuffling triggering, then only report corresponding MAC entity; A PHRMACCE form is used in dual link; The PH information of all activated community is comprised in PHR; Consider to distribute the new LCID PHRMACCE being used for dual link.
Current dual link uses a PHRMACCE form to report the PH information of all activated community, but how the concrete expansion PHRMACCE adopted reports details also not discuss.Therefore, in same PHRMACCE, the PH information of all activated community how is reported to be a problem demanding prompt solution.
