Fig. 7 has described on a plurality of carrier waves, and the single Serving cell from single sector is to the method 700 of given traditional UE702 transmission data, and wherein radio access network (RAN) 704 can be independent of a plurality of residential quarters or sector to traditional UE702 transmission data.Referring to Fig. 7, RAN704 determines that traditional UE702 is confined to receive data (square frame 710) from single Serving cell.Tradition UE702 is created as its serving sector (square frame 712) with the sector 1 of RAN704.For example, setting up serving sector can comprise: the pilot signal of UE monitoring and measurement sector 1 successfully resides on the sector 1 subsequently.After the serving sector that sector 1 is created as for traditional UE702, suppose that sector 1 is with uplink carrier F1(UL_F1) distribute to traditional UE702, and indicate traditional UE702 monitoring downlink carrier (perhaps frequency) F1(DL_F1) and downlink carrier F2(DL_F2), wherein on these two downlink carriers, 1 receive Mobile Termination data (square frame 714) from the sector.For example, traditional UE702 can use uplink carrier UL_F1 to report feedback, and wherein this feedback can be used for be adjusted from the sector 1 to traditional UE702 down-link transmitting power and data rate.In other example, downlink carrier DL_F1 and DL_F2 can be corresponding with different frequencies, wherein according to the MIMO physical layer in the version 7 and the DC-HSDPA in version 8 and/or 9 or two carrier wave DC-HSDPA, use these different frequencies and traditional UE702 to communicate.Downlink carrier DL_F1 and DL_F2 can comprise the corresponding HS-DSCH that sector 1 sends according to different frequency separately on different carrier.In addition, uplink carrier UL_F1 can comprise high-speed dedicated physics control carrier wave (HS-DPCCH), and traditional UE702 can 1 provide feedback to the sector by HS-DPCCH.

Sector 1 beginning of RAN704 sends signal to traditional UE702 on downlink carrier DL_F1 and DL_F2, can suppose traditional UE702 be tuned to and receive these downlink transmission (square frame 716).At square frame 718, tradition UE702 monitors the downlink pilot signal of each sector in its active set, and/or to monitoring from the downlink pilot signal of home cell or sector, so that identification also is not in the residential quarter in the active set of traditional UE702.Though clearly do not illustrate among Fig. 7, but traditional UE702 can also and measure downlink transmission in DL_F1 and DL_F2 monitoring, in order to physical layer (CQI (CQI) and/or H-ARQ information) is provided, wherein, can send described physical layer at reverse link physical layer channel (HS-DPCCH).Should be understood that the measurement that traditional UE702 carries out can form mobility event, this mobility event can cause the change to the active set of traditional UE702.

After in square frame 718, downlink pilot signal having been monitored a period of time, traditional UE702 on uplink carrier UL_F1 to the sector 1 transmitting channel feedback (square frame 720).For example, this channel feedback can comprise one or more in the following: the average pilot signal of each in the average signal strength of each in the downlink pilot signal of monitoring and/or the downlink pilot signal of monitoring and interference ratio (SIR).This channel feedback can be transmitted to the Serving RNC at RAN704 place, this Serving RNC uses this channel feedback to carry out mobile management, and it comprises active set is changed.Can control at Radio Resource and send described channel feedback in (RRC) message, physical layer is considered as data with this RRC message.The sector 1 of RAN704 receives the HS-DPCCH feedback from traditional UE702 on uplink carrier UL_F1, this channel feedback is transmitted to Serving RNC, and if necessary, Serving RNC is based on the active set (square frame 722) of this feedback updated tradition UE702.

Fig. 8 has described a kind of wireless communication system 800, and that sets up between traditional UE702 that this system 800 has been described at Fig. 7 and the sector 1 of RAN704 is connected.Correspondingly, Fig. 8 has described from the sector 1 to traditional UE702 two (2) downlink carrier DL_F1 and DL_F2, and Fig. 8 has also described the uplink carrier UL_F1 of the sector 1 from traditional UE702 to RAN704.

Though compare with on the single frequency band of single serving sector, communicating with object UE, in single serving sector, on a plurality of frequency band, communicate with same UE and can improve throughput, but aspect of the present invention relates to by communicating by letter between a plurality of serving sectors and at least one object UE and further improves throughput.Described aspect below, can distribute single uplink carrier (UL_F1 or UL_F2) to object UE, wherein on this single uplink carrier, in the physical layer feedback (HS-DPCCH feedback such as CQI and H-ARQ information) (as among Fig. 9 As) of a plurality of serving sectors transmissions at its each carrier wave (it forms single " carrier wave set " uniformly), perhaps can distribute a plurality of uplink carriers (UL_F1 and UL_F2) to object UE, wherein on described a plurality of uplink carriers, transmission is at the physical layer feedback of its different carrier wave " group ", these carrier waves can be distributed among the different sectors, as in Fig. 9 B.In addition, can in RRC message, (for example feed back by transmitting channel, measured average signal strength and average pilot SIR near the local downlink pilot signal of the sector the UE902), wherein any that RRC message can be in the available uplink carrier wave sends.

Fig. 9 A has described to send to given UE by a plurality of serving sectors the method 900 of data according to an aspect of the present invention.Referring to Fig. 9 A, RNC903 and UE902 are created as serving sector (square frame 950) with the sector 1906 of RAN904.For example, setting up sector 1906 can comprise: the pilot signal of UE902 monitoring and measurement sector 1906 successfully resides on the sector 1906 subsequently.After the serving sector that sector 1906 is created as for this UE, suppose that sector 1906 distributes to UE902 with uplink carrier (UL_F1), indicate UE902 that one or more downlink carriers (perhaps frequency) DL_F1 and DL_F2 are monitored in addition, wherein, on these downlink carriers, 1906 receive Mobile Termination data (square frame 916) from the sector.As following exemplary realization example with reference to Figure 10 A-10G describe in detail more, sector 1 906 can be at single downlink carrier (DL_F1 or DL_F2, but be not both) go up with UE902 and communicate, perhaps can be concomitantly on two carrier waves (DL_F1 and DL_F2) and UE902 communicate.

For example, UE902 can use uplink carrier UL_F1 to come the reporting channel feedback, and wherein Serving RNC can use this channel feedback to keep the active set of this UE.For example, can measured signal strength signal intensity and/or the SIR that be associated with home cell or sector be upgraded, wherein UL_F1 controls active set by described home cell or sector.In another example, downlink carrier DL_F1 and DL_F2 can be corresponding with different frequency, wherein according to the MIMO physical layer in the version 7 and the DC-HSDPA in version 8 and/or 9 or two carrier wave DC-HSDPA, use described different frequency and UE902 to communicate.Downlink carrier DL_F1 and DL_F2 can comprise two HS-DSCH that sent according to different frequency by sector 1 906.In addition, uplink carrier UL_F1 can comprise high-speed dedicated physics control carrier wave (HS-DPCCH).

Referring to Fig. 9 A, sector 1 906 beginnings send signal (square frame 914) to this UE on downlink carrier DL_F1 and DL_F2.UE902 monitors the downlink pilot signal of each sector in its active set, and/or to monitoring from the downlink pilot signal of home cell or sector, so that identification also is not in the residential quarter (square frame 916) in the active set of this UE.Should be understood that the measurement that UE902 carries out can cause mobility event, wherein when to this mobility event of network-reporting, can make Serving RNC 903 change the active set of UE902.For example, can by with version 8, version 9 and version 10 in identical mode, be configured in the measurement that UE902 carries out in the square frame 916 (it has and do not have compact model (CM) operation).In square frame 916 to after downlink pilot signal monitoring a period of time, UE902 on uplink carrier UL_F1 to the sector 1 906 transmitting channels feedbacks (square frame 918).For example, this channel feedback can comprise: based on the measurement of carrying out at square frame 916 UE902 of place, the average pilot SIR of each in the average signal strength of each in the downlink pilot signal of monitoring and/or the downlink pilot signal of monitoring.The active set (square frame 920) of UE902 from UE902 receive channel feedback, this mobility is transmitted to Serving RNC, and if necessary, Serving RNC 903 is upgraded based on channel feedback in the sector 1 906 of RAN904 on uplink carrier UL_F1.

Though clearly do not illustrate among Fig. 9 A, but UE902 can also and measure downlink transmission from sector 1 906 in DL_F1 and/or DL_F2 monitoring, in order to physical layer feedback (CQI (CQI) and/or H-ARQ information) is provided, physical layer feedback can go up to the sector 1 906 at the reverse link physical layer channel (HS-DPCCH) of UL_F1 and send, subsequently sector 1 906(its be in the active set of this UE) use this physical layer feedback to adjust data rate and/or the transmitted power level of sector 1 906 on DL_F1 and/or DL_F2.

At certain time point after a while, suppose that UE902 enters into Zone switched (square frame 922) between its current service sector 1 906 and another sector (" sector 2 908 ").Be to be understood that as those of ordinary skills HSDPA does not support traditionally that as employed in other wireless protocols " soft handover " this is to be introduced into because of HSDPA in version 5.Or rather, the HSDPA among the version 5+ supports " direct-cut operation " form in the down link side, makes at any given time, and only a Serving cell sends signal to object UE 902, is among the method that switches to new Serving cell even work as object UE 902.In other words, traditionally, there is not the overlapping period that is covered by a plurality of residential quarters in the object UE 902 for HSDPA version 5+.

Turn back to the aspect of Fig. 9 A, at square frame 924 places after both are added to the serving sector of UE902 with sector 1 906 and sector 2 908, can be from the Serving RNC 903 of RAN904 to sector 1 906 with sector 2 908 each different Mobile Termination data are provided, in order to transmit to UE902.From the angle of up link, any other sector in the active set of sector 1 906 and sector 2 908(and UE902) will upward transmit UE at their carrier waves (UL_F1 and/or UL_F2) separately and monitor.In an exemplary version, part is based on existing sector 2 908 in the active set of UE902, and sector 2 908 is chosen to be Serving cell or sector at UE902.Should be understood that in one example, described active set and up-link power control and scheduling authorization calculate tight association, and the quantity of active set must be equal to or less than the quantity of the uplink carrier of distributing to UE.Therefore, for example, the maximum quantity of the Serving cell on all downlink carriers is equal to or less than the quantity of uplink carrier.

Correspondingly, after sector 2 908 is created as second serving sector of UE, suppose that sector 2908 indication UE902 monitor one or more downlink carriers (or frequency) DL_F1 and DL_F2, wherein on these downlink carriers, 2 908 receive Mobile Termination data (square frame 926) from the sector.Describe in detail more with reference to the exemplary realization example of Figure 10 A-10G as following, sector 2 908 can be at single downlink carrier (DL_F1 or DL_F2, but be not both) go up with UE902 and communicate, perhaps concomitantly on two carrier waves (DL_F1 and DL_F2) and UE902 communicate.Should be understood that transmitted so that the Mobile Termination data of transmission need not be identical with sector 2 908 by sector 1 906, it is identical that data volume also needs not be.Or rather, the Serving RNC that sector 1 906 and sector 2 908 are controlled can participate in load balance, so that by suitable mode, will be distributed between sector 1 906 and the sector 2 908 for the data to UE902 transmission and be distributed between the DL_F1 and/or DL_F2 of sector 1 906 and sector 2 908.This present load that can relate on 903 pairs of different sectors of Serving RNC and the different carrier is considered, also considers other factors, for example, for concrete carrier wave, which sector is " host sectors ", and which sector is " auxiliary sector ", as below being discussed in detail more.

Referring to Fig. 9 A, sector 2 908 beginnings send signal (square frame 928) to UE on downlink carrier DL_F1 and/or DL_F2, and sector 1 906 continues to send signal (square frame 930) to UE on downlink carrier DL_F1 and/or DL_F2.In square frame 928 and 930, can suppose UE902 be tuned to these downlink transmission, and receive these downlink transmission.

In square frame 932, UE902 monitors the downlink pilot signal of each sector in its active set, and/or to monitoring from the downlink pilot signal of home cell or sector, so that identification also is not in the residential quarter in the active set of this UE.Should be understood that the measurement that UE902 carries out can cause mobility event, wherein when transmitting this mobility event to Serving RNC, can make Serving RNC change the active set of this UE.For example, can by with version 8, version 9 and version 10 in identical mode, be configured in the measurement of being undertaken by UE902 in the square frame 932 (it has and do not have compact model (CM)).To after downlink pilot signal monitoring a period of time, UE902 is transmitting channel feedback (square frame 934) on uplink carrier UL_F1 in square frame 932.For example, this channel feedback can comprise: based on the measurement of in square frame 932, being undertaken by UE902, and the average pilot SIR of each in the average signal strength of each in the downlink pilot signal of monitoring and/or the downlink pilot signal of monitoring.Aspect Fig. 9 A, can suppose that the sector 1 906 of RAN904 and sector 2 908 feed back from the UE902 receive channel on uplink carrier UL_F1.For example, sector 1 906 and sector 2 908 can all be among the active set of UL_F1, this means that sector 1 906 and sector 2 908 on UL_F1, monitor actively to the ul transmissions from UE902.Therefore, when in square frame 934, when UE902 sent signal at UL_F1, sector 1 906 and sector 2 908 all received transmission.At this moment, each in sector 1 906 and the sector 2 908 is transmitted to Serving RNC 903 with channel feedback, and if necessary, Serving RNC 903 upgrades the active set (square frame 936,938) of UE902 based on this channel feedback.

Though clearly do not illustrate among Fig. 9 A, but UE902 can also and measure downlink transmission from sector 1 906 and sector 2 908 in DL_F1 and/or DL_F2 monitoring, in order to physical layer feedback (CQI (CQI) and/or H-ARQ information) is provided, described physical layer feedback can be at the reverse link physical layer channel of UL_F1 (for example, HS-DPCCH) go up to the sector 1 906 and sector 2 908 send, subsequently sector 1 906 and sector 2 908 use these physical layer feedback be adjusted on DL_F1 and/or the DL_F2 from each sectors of data speed and/or transmitted power level.

Single uplink carrier UL_F1 is distributed to UE902 in the aspect of Fig. 9 A that discusses in the above, sends physical layer feedback to serving sector 1 906 and serving sector 2 908 on this uplink carrier UL_F1.Therefore, based on from single uplink carrier UL_F1(namely, " grappling " carrier wave) physical layer feedback, on the meaning of controlling from each carrier wave of each sector, with regard to power control aspect, are the parts of same " carrier wave set " from downlink carrier DL_F1 and/or the DL_F2 of sector 1 906 and sector 2 908.In the each side of Fig. 9 B that next describes, distribute a plurality of uplink carriers to UE902, provide feedback at described uplink carrier.In this version, each uplink carrier of distributing to UE can be associated with the different carrier group.

Fig. 9 B has described to send to UE902 by a plurality of serving sectors the another kind of method of data according to an aspect of the present invention.Referring to Fig. 9 B, square frame 910-924 is as described at Fig. 9 A, so for for the purpose of brief, will it be described further.

Referring to Fig. 9 B, in square frame 924, add sector 2908 as after the other serving sector, sector 2 908 indication UE902 monitor one or more downlink carriers (or frequency) DL_F1 and DL_F2, go up the 2 908 reception Mobile Termination data (square frame 940) from the sector at described one or more downlink carriers (or frequency) DL_F1 and DL_F2, it is similar to the square frame 926 among Fig. 9 A.But different with Fig. 9 A, in square frame 940, second uplink carrier (UL_F2) is also distributed to UE902 in sector 2 908.

Referring to Fig. 9 B, sector 2 908 beginnings send signal (square frame 942) to UE on downlink carrier DL_F1 and/or DL_F2, and sector 1 906 continues to send signal (square frame 944) to UE on downlink carrier DL_F1 and/or DL_F2.In square frame 942,944, UE902 be tuned to these downlink transmission, and receive these downlink transmission.In square frame 946, UE902 monitors the downlink pilot signal of each sector in its active set and/or to monitoring from the downlink pilot signal of home cell or sector, so that identification also is not in the residential quarter in the active set of this UE902.Should be understood that the measurement that UE902 carries out can cause mobility event, wherein when transmitting this mobility event to Serving RNC 903, make Serving RNC 903 change the active set of UE902.For example, can by with version 8, version 9 and version 10 in identical mode, be configured in the measurement of being undertaken by UE902 in the square frame 946 (it has and do not have compact model (CM)).

Institute short discussion as mentioned, among uplink carrier UL_F1 and the UL_F2 each can be associated with the carrier wave set of its oneself active set and its oneself, wherein each carrier wave set is corresponding with one group of sector, a physical layer feedback that provides from uplink carrier UL_F1 or UL_F2 wherein is provided, down-link transmitting power and/or the data rate of this group sector are controlled.When having two or more uplink carriers, as in Fig. 9 B, network is configured (that is, by the Serving RNC 903 of network that sector 1 906 and sector 2 908 are controlled) to each carrier wave set, makes the carrier wave that is positioned among the same carrier wave set have similar overlay area.For example, the carrier wave supported of identical serving sector can jointly constitute the part of a carrier wave set.In Fig. 9 B, because two uplink carrier UL_F1 among the DC HSUPA and UL_F2 all have their active set, so there are two carrier wave set (unless using anchor carrier in up link).

In one example, each among two uplink carrier UL_F1 and the UL_F2 can be controlled their carrier wave set (data speed and/or transmitting power are made amendment) separately independently.Perhaps, one in the uplink carrier can comprise " grappling " carrier wave, and another uplink carrier comprises the carrier wave that matches mutually with auxiliary uplink carrier at least.The downlink carrier of another " not pairing " can be put in any in these two carrier wave set.The mode that can have similar handoff boundary by the carrier wave in the same carrier wave set realizes grouping.

The measurement of being undertaken by UE902 in square frame 946 to downlink pilot signal can trigger " mobility event ".With regard to mobility, in the anchor carrier version, each mobility event (perhaps each triggering that changes at potential active set, for example, soft handover, to going offline of the conversion of new or different Serving cells, old Serving cell etc.) can be based on this anchor carrier (UL_F1).In this case, will assist uplink carrier (UL_F2) to be considered as " obsolete ", event 2x is used for these measurements.The ability that UE902 measures auxiliary uplink carrier under the situation of not using compact model (CM) can be conducive to the new residential quarter on this frequency is identified.For example, suppose that UL_F1 is uplink anchor carrier, along with UE902 1 906 moves to sector 2 908 from the sector, have only when the DL_F2 of sector 1 906 adds in the active set of UL_F2, just can increase the service from the DL_F1 on the sector 1 906.When UL_F1 was anchor carrier, new mobility event can also impel UE902 report DL_F2 intensity.

In the version that substitutes, not to trigger report from UE902 based on the channel quality of the residential quarter on the grappling frequency individually, can also trigger report from UE902 based on the channel quality that records in other non-grappling frequency, thereby in network, exist under the situation of lack of balance load helpful.

In another version that substitutes, replace via single anchor carrier, can be via realize the mobility event management on the basis of each carrier wave set.As mentioned above, each carrier wave set is kept active set.In one example, suppose that UE keeps two independently active sets (active set correspondence carrier wave set separately), can implement the search to two carrier wave set under the situation of not using CM.In this case, when UE902 is moving away sector 2 908 and is going to sector 1 906, when the DL_F1 on the sector 1 906 adds active set on the UL_F1 to, (replace when the DL_F2 on the sector 1 906 adds the active set of UL_F2 to), can increase from the service on the DL_F1 of sector 1 906.This causes the bigger expansion from the DL_F1 service of sector 1 906.This option may need DC-HSUPA to support.In addition, can alleviate the problem of the physical layer feedback channel on the up link by allowing to carry separately on each uplink carrier in the uplink carrier (UL_F1, UL_F2) of pairing the HS-DPCCH of each downlink carrier (DL_F1, DL_F2).

Describe in detail more with reference to the exemplary realization example of Figure 10 A-10G as following, sector 2 908 can be at single downlink carrier (DL_F1 or DL_F2, but be not both) go up with given UE902 and communicate, perhaps can go up with given UE902 at two carrier waves (DL_F1 and DL_F2) concomitantly and communicate.Can be with the downlink carrier DL_F1 in the sector 2 908 and DL_F2(if present) be considered as according to the downlink carrier DL_F1 in basic and the sector 1 906 and DL_F2(if present) similar mode is configured, except from the different serving sectors transmissions of given UE.

Turn back to Fig. 9 B, in square frame 946 to after downlink pilot signal monitoring a period of time, 1 906 transmitting channels feed back (square frame 948) to given UE902 to the sector on uplink carrier UL_F1, and also 2 908 transmitting channels feed back (square frame 950) to the sector on uplink carrier UL_F2 individually.Therefore, the version shown in Fig. 9 B is corresponding with non-anchor carrier version, thereby individually the carrier wave set of UL_F1 and UL_F2 is controlled.Though do not illustrate among Fig. 9 B, but a kind of alternative method of this method is anchor carrier version (following it is described in further detail), by this method, can use single uplink carrier (UL_F1 or UL_F2) to come to provide channel feedback (that is, can send the measured pilot tone of two carrier wave set in anchor carrier) for two carrier wave set.In one example, uplink carrier UL_F1 with comprise sector 1 906 at least in downlink carrier DL_F1 and/or the first carrier group of DL_F2 be associated, uplink carrier UL_F2 with comprise sector 2 908 at least in downlink carrier DL_F1 and/or second carrier wave set of DL_F2 be associated.In addition, the channel feedback that sends in square frame 948 and 950 can comprise: based on the measurement of in square frame 946, being undertaken by given UE902, and the average pilot SIR of each in the average signal strength of each in the downlink pilot signal of monitoring and/or the downlink pilot signal of monitoring.

Though clearly do not illustrate among Fig. 9 B, but this given UE902 can also and measure downlink transmission from sector 1 906 and sector 2 908 in DL_F1 and/or DL_F2 monitoring, in order to provide physical layer feedback (for example, CQI (CQI) and/or H-ARQ information), can the reverse link physical layer channel (HS-DPCCH) of UL_F1 and/or UL_F2 go up to the sector 1 906 and sector 2 908 send these physical layer feedback, subsequently sector 1 906 and sector 2 908 use these physical layer feedback adjust on DL_F1 and/or the DL_F2 from each sectors of data speed and/or transmitted power level.A plurality of uplink carrier UL_F1 and UL_F2 can allow the HS-DPCCH information of the carrier wave in the same carrier wave group of this given UE902 to encode, and these information are encoded together, and send at the uplink carrier corresponding with this carrier wave set.For example, if UE902 has two downlink carriers (DL_F1 and DL_F2) and two uplink carriers (UL_F1 and UL_F2); This option will be encoded at the HS-DPCCH of these two downlink carriers (DL_F1 in the sector 1 and/or 2 and DL_F2) on these two uplink carriers.

Turn back to Fig. 9 B, the sector 1 906 of RAN904 is on uplink carrier UL_F1, from given UE902 receive channel feedback, and this channel feedback is transmitted to Serving RNC, and if necessary, Serving RNC is adjusted the active set (square frame 952) of this given UE902 based on this channel feedback.Equally, the sector 2 908 of RAN904 is on uplink carrier UL_F2, receive feedback from given UE902, and this channel feedback is transmitted to Serving RNC, and words if necessary, then Serving RNC is adjusted the active set (square frame 954) at this given UE902 of UL_F2 based on this channel feedback.

In addition, among Fig. 9 A and Fig. 9 B each has been described following scene: given UE902 sets up sector 1 906 as the initial service sector, after a while this given UE902 enter between sector 1 906 and the sector 2 908 switching area or when regional, add sector 2 908 as another serving sector.In an alternative version, power up simply in the switching area that this given UE902 can be between sector 1 906 and sector 2 908 or the zone, in this case, set up concurrently sector 1 906 and sector 2 908 both, as the serving sector of UE902.

In addition, the Node B with sector 1 906 among Fig. 9 A and Fig. 9 B and sector 2 908 are associated can have different transmission power capabilities.For example, support the Node B of sector 1 906 macrocell, Microcell or picocell can be supported in sector 1 906, it is compared with the Node B of supporting sector 2 908, can cause different transmit power capacity.This transmission power capabilities difference can cause following scene: in this scene, allow different service cells can improve throughput in the different carrier operation.

In the version that substitutes, as mentioned above, be substituted in uplink carrier UL_F1 and UL_F2 and go up the independent feedback (channel feedback or physical layer feedback) that sends for two carrier wave set, in described a plurality of uplink carriers can be appointed as " grappling " uplink carrier.In this case, with regard to physical layer feedback, can be used for each downlink carrier (from the DL_F1 of sector 1 906 and/or DL_F2, from the DL_F1 of sector 2 908 and/or DL_F2 etc.) HS-DPCCH information combined coding to a code word (as at the version 8 of DC HSDPA or at DC HSDPA together with in the version 9 of MIMO and DB DC HSDPA or in the version 10 at 4C HSDPA), send at the grappling uplink carrier subsequently.Should be understood that, use single anchor carrier if represent a plurality of carrier wave set, then the serving sector that is associated with this anchor carrier can be transmitted this UE feedback (to other serving sector), perhaps can monitor simultaneously anchor carrier by each (for example, each carrier wave in the active set of this anchor carrier) at least in these carrier waves.

Below, a plurality of realization examples of the processing of Fig. 9 A and Fig. 9 B are provided with reference to Figure 10 A-10G.More specifically, each width of cloth figure among Figure 10 A-10G has described the different articulation set that can set up between the UE902 of Fig. 9 A-9B and serving sector 1 906 and sector 2 908.

In Figure 10 A, realization example according to the method for Fig. 9 A, described communication system 1000a, wherein, in serving sector 1 906 and the serving sector 2 908 each (that is, DL_F1) communicates with UE902, distributes single uplink carrier (namely to UE902 by identical, single downlink carrier, UL_F1), provide feedback at carrier wave set at this single uplink carrier.Therefore, in the example of Figure 10 A, do not use the second downlink carrier DL_F2.Should be understood that, the omission of downlink carrier DL_F2 can fail to support downlink carrier DL_F2(sector 1 906 and sector 2 908 to dispose realization by the single carrier frequency rate based on serving sector 1 and/or 2), perhaps, alternatively, can determine that the load level of downlink carrier DL_F2 is higher than thresholding based on Serving RNC, the resource that make to be used for supporting UE902 at downlink carrier DL_F2 current be disabled.

Referring to Figure 10 A, suppose that sector 1 906 is corresponding with " master " sector of downlink carrier DL_F1, sector 2 908 is corresponding with " assisting " serving sector of downlink carrier DL_F1.In each aspect of the present invention, each specific downlink carrier can obtain single main serving sector and at least one assistant service sector is supported.Usually, compare with the assistant service sector that is used for specific downlink carrier, main serving sector is more lasting.In addition, opposite with the assistant service sector, RNC can be directed to main serving sector with more down link Mobile Termination data.In other example, to compare with the assistant service sector, main serving sector can be related with the low load of associated carrier, and/or can have with the better of UE902 and be connected.Downlink carrier DL_F1 in sector 1 906 and the sector 2 908 all carries unique HS-DSCH that can be monitored by UE902.In this case, by same carrier wave or frequency (that is, and DL_F1) two HS-DSCH on, can be from the sector 1 906 and sector 2 908 transmit the transmission block of two uniquenesses to UE902.In other words, different sectors sends different data (that is, the soft handover formation contrast with in the non-HSDPA agreement wherein in non-HSDPA agreement, sends identical data redundantly in Zone switched) in identical carrier wave.Such transmission plan can be called unifrequency double small district HSDPA(SF-DC-HSDPA).Should be understood that in the reality of often fully not using this system was disposed, SF-DC-HSDPA can provide balancing dynamic load.As shown in Figure 10 A, each in main serving sector 1 906 and the assistant service sector 2 908 can be to monitoring and receive from signal UE902, that send at uplink carrier UL_F1.

In Figure 10 B, realization example according to the method for Fig. 9 A, described communication system 1000b, wherein, in serving sector 1 906 and the serving sector 2 908 each communicates with UE902 by single downlink carrier (that is, respectively by DL_F1 and DL_F2), distributes single uplink carrier (namely to UE902, UL_F1), provide feedback at carrier wave set at this single uplink carrier.Therefore, in the example of Figure 10 B, downlink carrier frequency DL_F1 and the DL_F2 that use respectively sector 1 906 and sector 2 908 can be mutually orthogonal, in order to reduce the interference at UE902 place.Referring to Figure 10 B, suppose that downlink carrier DL_F1 in the sector 1 906 and the downlink carrier DL_F2 in the sector 2 908 all carry unique HS-DSCH that can be monitored by UE902.In this case, by two HS-DSCH on different carrier waves or the frequency (that is, DL_F1 and DL_F2), can be from the sector 1 906 and sector 2 908 transmit the transmission block of two uniquenesses to UE902.In the exemplary version of Figure 10 B, because serving sector 1 906 communicates via DL_F1 and UE902, and serving sector 2 908 communicates via DL_F2 and UE902, so both all are " host sectors " at their concrete downlink carrier for serving sector 1 906 and serving sector 2 908, this is owing to do not have subcarrier among Figure 10 B.As shown in Figure 10 B, each in serving sector 1 906 and the serving sector 2 908 can be to monitoring and receive from signal UE902, that send at uplink carrier UL_F1, even serving sector 2 908 just sends signal at DL_F1.In one example, serving sector 2 908 can transship, and it causes serving sector 2908 to fail to provide the down link support at DL_F1, decodes although still can go up the feedback of the UE902 that sends to the UL_F1 as anchor carrier.

In addition, referring to Figure 10 B, in another example, suppose that sector 1 906 and sector 2 908 boths support downlink carrier DL_F1 and DL_F2.But, suppose that further DL_F2 on the sector 1 906 and the DL_F1 on the sector 2 908 are heavy duty, and the DL_F2 on the DL_F1 on the sector 1 906 and the sector 2 908 is underloaded.In this case, 1 906 couples of UE902 serve from the sector on DL_F1, and the 2 908 couples of UE902 serve (as shown in Figure 10 B) and will cause throughput to increase from the sector on DL_F2.Should be understood that, have a lot of different scenes, in these scenes, on different carrier, from different sectors UE902 served the service that can improve UE902.

In Figure 10 C, realization example according to the method for Fig. 9 B, described communication system 1000c, wherein, in serving sector 1 906 and the serving sector 2 908 each by single (and different) downlink carrier (namely, be respectively DL_F1 and DL_F2) communicate with UE902, distribute two uplink carriers (namely to UE902, UL_F1 and UL_F2), provide at each carrier wave set (that is first carrier group that, comprises the DL_F2 of sector 2 908 at least at these two uplink carriers, and second carrier wave set that comprises the DL_F1 of sector 1 906 at least) feedback.The example class of Figure 10 C is similar to top with reference to the described example of Figure 10 B, except Figure 10 C provides two uplink carriers (UL_F1 and UL_F2) to UE902, to replace outside the single uplink carrier (UL_F1) among Figure 10 B, it forms carrier wave set and active set at two uniquenesses of UE902.Correspondingly, two uplink carriers (UL_F1 and UL_F2) allow UE902 by UL_F1 and UL_F2 the carrier wave set of two uniquenesses to be controlled individually respectively, and are described with reference to Fig. 9 B as mentioned.For example, uplink carrier UL_F1 can provide the feedback that is associated with first carrier group (it comprises the downlink carrier DL_F1 on the sector 1 906 at least), and uplink carrier UL_F2 can provide the feedback that is associated with second carrier wave set (it comprises the downlink carrier DL_F2 on the sector 2 908 at least).

Perhaps, referring to Figure 10 C, even provide two uplink carrier UL_F1 and UL_F2 to UE902, still can provide the feedback at two carrier wave set by single anchor carrier (UL_F1 or UL_F2).In this case, sector 1 906 and sector 2 908 boths are in the active set of this anchor carrier, make two sectors all will carry out suitable decoding to the feedback on this anchor carrier.Since itself and the similitude of Figure 10 B, so for brevity, will omission further describing Figure 10 C.

Referring to Figure 10 C, in one example, suppose that sector 1 906 is corresponding with the hot spot region of supporting downlink carrier DL_F1 and DL_F2, and downlink carrier DL_F2 is supported in 2 908 of sectors.In this case, when UE902 Zone switched between sector 1 906 and sector 2 908, and compare more close sector 2 908 o'clock with sector 1 906, by from the sector 1 906 2 908 on DL_F2, UE902 being served on the DL_F1 and from the sector, can obtain higher throughput.Therefore, in non-general deployment scenario (that is, not all sector is all supported in the scene of DL_F1 and DL_F2), can realize the scope expansion to the service of UE902.

Should be understood that, Figure 10 A-10C relates to by the UE902 of following configuration: carry out on the downlink carrier of different sectors (in Figure 10 A, on the DL_F1 on the DL_F1 on the sector 1 906 and sector 2 908, perhaps as among Figure 10 B and Figure 10 C, on the DL_F2 on the DL_F1 on the sector 1 906 and sector 2 908), receive the operation of the transmission block of two uniquenesses.The characteristic of this UE902 can be depicted as the UE of compatible DC-HSDPA and/or the UE of compatible SF-DC-HSDPA.Below, with reference to Figure 10 D-10G UE902 is described, this UE902 can be concomitantly be tuned to three (3) or more transmission block on a plurality of downlink carriers.Can be concomitantly be tuned to the characteristic of UE902 of three or more transmission blocks on a plurality of downlink carriers can be depicted as the UE of the compatible 4C-HSDPA in the version 10.

In Figure 10 D, realization example according to the method for Fig. 9 A, described communication system 1000d, wherein, serving sector 1 906 by single downlink carrier (namely, DL_F1) communicate with UE902, serving sector 2 908 by a plurality of downlink carriers (namely, DL_F1 and DL_F2) communicate with UE902, distribute single uplink carrier (namely to UE902, UL_F1 or anchor carrier), provide at each carrier wave set (that is first carrier group that, comprises DL_F1 and the DL_F2 of sector 2 908 at least at this single uplink carrier, at least feedback second carrier wave set that comprises the DL_F1 of sector 1 906).Therefore, in the example of Figure 10 D, (that is, DL_F1) (that is, DL_F2) both support UE902 with non-overlapped carrier wave by overlapping carrier wave for sector 1 906 and sector 2 908.In the exemplary version of Figure 10 D, serving sector 1 906 is for the host sectors of supporting DL_F1, and serving sector 2 908 is for the auxiliary sector of supporting DL_F1.In addition, in Figure 10 D, because sector 2 908 is unique sectors of supporting DL_F2, so there is not the auxiliary sector meaning of supporting DL_F2, sector 2 908 is for DL_F2 " host sectors ".Referring to Figure 10 D, suppose that downlink carrier DL_F1 in the sector 1 906 and the downlink carrier DL_F1 in the sector 2 908 and DL_F2 all carry unique HS-DSCH that can be monitored by UE902.In this case, by three HS-DSCH on different carrier waves or the frequency (that is, DL_F1 and DL_F2 in the DL_F1 in the sector 1 906 and the sector 2 908), can be from the sector 1 906 and sector 2 908 transmit three (3) unique transmission blocks to UE902.As shown in Figure 10 D, because each in main serving sector 1 906 and the assistant service sector 2 908 is supported F1, and because sector 1 906 and sector 2 908 all be in the active set of anchor carrier UL_F1, so each in sector 1 906 and the sector 2 908 can be to monitoring and receive from signal UE902, that send at the uplink carrier UL_F1 as anchor carrier.

In Figure 10 E, realization example according to the method for Fig. 9 B, described communication system 1000e, wherein, serving sector 1 906 by single downlink carrier (namely, DL_F1) communicate with UE902, serving sector 2 908 communicates with UE902 by a plurality of downlink carriers (that is, DL_F1 and DL_F2), distributes two uplink carriers (namely to UE902, UL_F1 or UL_F2), provide feedback at carrier wave set at these two uplink carriers.The example class of Figure 10 E is similar to top with reference to the described example of Figure 10 D, except Figure 10 E provides two uplink carriers (UL_F1 and UL_F2) to UE902, outside the single uplink carrier (UL_F1) among replacement Figure 10 D, thereby formation is at carrier wave set and the active set of two uniquenesses of UE902.Correspondingly, two uplink carriers (UL_F1 and UL_F2) allow UE902 that the carrier wave set of two uniquenesses is controlled individually, perhaps by the given anchor carrier of from UL_F1 and UL_F2, selecting the carrier wave set of two uniquenesses is controlled, described with reference to Fig. 9 B as mentioned.For example, uplink carrier UL_F1 can provide the feedback that is associated with first carrier group (it comprises the downlink carrier DL_F1 on the sector 1 906 at least), and uplink carrier UL_F2 can provide the feedback that is associated with second carrier wave set (it comprises downlink carrier DL_F1 and DL_F2 on the sector 2 908 at least).Perhaps, even distribute two independent uplink carriers to UE, still can provide the feedback at these two carrier wave set by single anchor carrier (UL_F1 or UL_F2), as mentioned above.Owing to the similitude of Figure 10 D, so for brevity, will omit further describing Figure 10 E.
