Description
Technical field
Non-limiting and exemplary embodiment of the present disclosure relates to wireless communication field.More specifically, embodiment here relates at the method and apparatus supporting to use in the wireless network of dual link.
Background technology
In Long Term Evolution-senior (" LTE-A ") version 12 (Rel-12), dual link as shown in Figure 1 (" DC ") is such one operation, wherein given subscriber equipment (" UE " ") consumes the radio resource provided by least two different nexus; these two different nexus such as act the leading role into Node B (" MeNB ") and auxiliary eNB (" SeNB "); in RRC_CONNECTED pattern, the two connects via nonideal back haul link.MeNB can at least terminate S1-Mobility Management Entity (" MME ", not shown) and serve as the mobility anchor point being directed to core net (" CN ").SeNB provides additional radio resource for UE.Be different from existing carrier aggregation (" CA ") technology, at MeNB and SeNB place for the scheduling of DC normally independently, and do not coordinate due to imperfect back haul link.In CA, total transmitted power should be distributed to CC by multiple up link (" UL ") component carrier (" CC ") and dynamically shared afterwards considering how many UL resource.But, the coordination of scheduler stage cannot be carried out for DC, MeNB and SeNB, and it is shared therefore can not to realize dynamic power between which.Therefore, for the UE in DC, it is very likely that the transmission of UL to MeNB in identical subframe and exceed the maximum transmit power of UE to total transmitted power that another UL of SeNB transmits.
Can not occur due to the independent scheduler at MeNB and SeNB place in order to ensure excessive UE Power Limitation, current suggestion MeNB is for the maximum transmit power P of the transmission to MeNB
cMAX_MeNBcarry out configuration UE, and similarly, with the maximum transmit power P of the transmission to SeNB
cMAX_SeNBcarry out configuration UE, wherein
and
represent the maximum transmit power that UE self can support.Can find out that UE maximum transmit power semi-statically divides between two connections.Here the semi-static power divider between MeNB and SeNB may be simple and be easy to realize.But DC performance may be told experience in the amount of gulping down in UL covering and/or UL and be worsened, because available UE transmitted power fully and is not completely used.Such as, when MeNB does not have UL to transmit in some subframes, the power being remained for MeNB by UE in advance can not be released to be used by SeNB, because SeNB can not the dynamic dispatching judgement of MeNB in subsequent subframe.In addition, be usually far longer than towards small cell towards the path loss of macrocell.Therefore, in order to realize similar target Signal to Interference plus Noise Ratio (" the SINR ") level at two eNB places, the transmitted power that UE will distribute to MeNB higher than SeNB, if macrocell is as MeNB connection, small cell connects as SeNB.In this case, when not having UL to transmit on MeNB, most UL transmitted powers will not used.

1correspond to conservative configuration and calculate based on the semi-static division maximum power associated with MeNB or SeNB, and TPC
2+ MCS
2calculate based on total transmitted power corresponding to radical configuration, two that suppose at DC here one of to connect not ul transmissions, and total UE transmitted power may be used for two in target-subframe connect another connect.
Then, as shown in Figure 4 B, TPC is being received
0+ MCS
0, TPC

As can be seen from description above, when UE receives the schedule information coming from both MeNB and SeNB in subframe n, it can select conservative configurations for target-subframe n+4 or radical configuration according to dispatch state.If dispatch state is both MeNB with SeNB have ul transmissions in identical subframe, then UE can select the configuration of guarding.Comparatively speaking, if dispatch state is one of both MeNB and SeNB do not have ul transmissions, then UE can select radical configuration, and wherein UE can use transmitted power available arbitrarily, even comprise the maximum transmit power that UE self can support, discuss namely
thus, UE can realize higher throughput performance and the covering of better up link.
Fig. 5 A-5C is the schematic diagram occurred according to the scene of the UL transmission of drawing on only SeNB of exemplary embodiment of the present disclosure.As shown in Figure 5A, SeNB sends new DCI format, to configure two groups of TPC command and MCS grade, i.e. TPC to the UE expected in subframe n
1+ MCS
1and TPC
2+ MCS
2.Owing to not coming from the uplink scheduling of MeNB, UE selects the radical ul transmissions be configured to for arriving SeNB, because there is no ul transmissions on MeNB, and as shown in figure 5b, in subframe n+2, feed back it to SeNB select TPC
2+ MCS
2.Then, go out as shown in Figure 5 C, in subframe n+4, UE is only according to the configuration TPC selected
2+ MCS
2perform the ul transmissions of SeNB, this by use fully can UE transmitted power realize optimum up link and cover and throughput performance.
Although do not illustrate further in Fig. 4 A-4C and Fig. 5 A-5C, for at such as " n+4 " " in target-subframe in the uplink data that sends; at corresponding eNB place existence two method of reseptances, the reception of wherein a kind of method of reseptance to be the reception of implicit expression and another method of reseptance be display.In the reception of implicit expression, MeNB or SeNB can utilize two kinds of configurations to detect physical uplink link shared channels (" PUSCH ") data respectively.That is, MeNB or SeNB can perform blind Detecting to uplink data, because report is unnecessary, therefore will result in skipped step as shown in Figure 5 B.In explicit reception, before data receiver in subframe " n+4 ", UE can send such as dispatch request (" SR ") or mixed automatic repeat request and confirm that the uplink control signaling message of (" HARQ-ACK ") form notifies at subframe " n+1 ", " n+2 " or " n+3 " configuration that eNB selects.
It is to be noted that above-mentioned two groups of TPC and MCS are only exemplary embodiments of the present disclosure, and the scope of the present disclosure should be not limited thereto.As previously discussed, TPC and MCS more than two groups can advantageously be used according to the disclosure.Further, based on instruction of the present disclosure, it will be appreciated by those skilled in the art that and be alternative in its combination of use, multiple TPC or multiple MCS can be used respectively.Owing to it will be appreciated by those skilled in the art that how regulate transmitted power according to TPC (such as in an absolute way or the mode of stepping), the details about this respect is omitted unnecessarily to obscure the scope of the present disclosure.
