Referring to Fig. 9 A, sector 1906 begins at and sends signal (square frame 914) to this UE on downlink carrier DL_F1 and DL_F2.The downlink pilot signal of each sector in its active set is monitored by UE902, and/or the downlink pilot signal from home cell or sector is monitored, in order to identify but without the community (square frame 916) in the active set being in this UE.It should be appreciated that the measurement that UE902 carries out can cause mobility event, wherein when to this mobility event of network-reporting, it is possible to make Serving RNC 903 change the active set of UE902.For example, it is possible to by the mode identical with version 8, version 9 and version 10, be arranged in the measurement (it has and do not have compact model (CM) operation) that in square frame 916, UE902 carries out.After downlink pilot signal being monitored a period of time in square frame 916, UE902 sends channel feedback (square frame 918) on uplink carrier UL_F1 to sector 1906.Such as, this channel feedback may include that based in the square frame 916 place UE902 measurement carried out, the average signal strength of each in the downlink pilot signal monitored and/or the average pilot SIR of each in the downlink pilot signal monitored.The sector 1906 of RAN904 receives channel feedback from UE902 on uplink carrier UL_F1, this mobility is transmitted to Serving RNC, and if necessary, Serving RNC 903 updates the active set of UE902 (square frame 920) based on channel feedback.
Although Fig. 9 A is not explicitly illustrated, but UE902 can also monitor on DL_F1 and/or DL_F2 and measure the downlink transmission from sector 1906, to provide physical layer feedback (CQI (CQI) and/or H-ARQ information), physical layer feedback can send to sector 1906 on the reverse link physical layer channel (HS-DPCCH) of UL_F1, subsequently sector 1906(its be in the active set of this UE) use this physical layer feedback to adjust the sector 1906 data rate on DL_F1 and/or DL_F2 and/or transmitted power level.
In certain later point, it is assumed that UE902 enters into Zone switched (square frame 922) between its current service sector 1906 and another sector (" sector 2908 ").As those of ordinary skill in the art it should be appreciated that HSDPA supports such as " soft handover " that use in other wireless protocols traditionally, this is because HSDPA is introduced in version 5.More precisely, HSDPA in version 5+ holds " direct-cut operation " form downlink is collateral so that at any given time, only one Serving cell sends signal to target UE902, even if when target UE902 is among the method being switched to new Serving cell.In other words, traditionally, for the target UE902 of HSDPA version 5+, it is absent from being carried out, by multiple communities, the overlapping period that covers.
Return to the aspect of Fig. 9 A, after both sector 1906 and sector 2908 are added to the serving sector of UE902 by square frame 924 place, different Mobile Termination data can be provided, in order to transmit to UE902 from the Serving RNC 903 of RAN904 to sector 1906 with each sector 2908.From the angle of up-link, other sector any in the active set of sector 1906 and sector 2908(and UE902) on the carrier wave (UL_F1 and/or UL_F2) of each of which, UE transmission will be monitored.In an exemplary version, it is based partially in the active set of UE902, there is sector 2908, sector 2908 is chosen to be the Serving cell for UE902 or sector.It should be appreciated that in one example, described active set controls with up-link power and scheduling authorization calculating tight association, and the quantity of active set is necessarily equal to or less than the quantity of the uplink carrier 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 2908 is created as the second service sector of UE, assuming that sector 2908 indicates UE902 to monitor one or more downlink carriers (or frequency) DL_F1 and DL_F2, downlink carrier wherein receives from sector 2908 Mobile Termination data (square frame 926) in these lower.As described in more detail in realized example referring to Figure 10 A-10G exemplary, sector 2908 can at single downlink carrier (DL_F1 or DL_F2, but it is not both) above communicate with UE902, or above communicate with UE902 two carrier waves (DL_F1 and DL_F2) concomitantly.It should be appreciated that forwarded so that the Mobile Termination data transmitted need not be identical by sector 1906 and sector 2908, data volume is also without being identical.Or rather, the Serving RNC that sector 1906 and sector 2908 are controlled can participate in load balance, by will pass through suitable in the way of, by be used for UE902 transmission data be distributed between sector 1906 and sector 2908 and also be distributed between DL_F1 and/or DL_F2 in sector 1906 and sector 2908.This can relate to Serving RNC 903 and the present load on different sectors and different carrier is accounted for, it is also contemplated that other factors, for instance, for concrete carrier wave, which sector is " host sectors ", and which sector is " auxiliary sector ", will be discussed in greater detail as following.
Referring to Fig. 9 A, sector 2908 begins at and sends signal (square frame 928) to UE on downlink carrier DL_F1 and/or DL_F2, and sector 1906 continues to send signal (square frame 930) to UE on downlink carrier DL_F1 and/or DL_F2.In square frame 928 and 930, it can be assumed that UE902 be tuned to these downlink transmission, and receive these downlink transmission.
In square frame 932, the downlink pilot signal of each sector in its active set is monitored by UE902, and/or the downlink pilot signal from home cell or sector is monitored, in order to identify but without the community in the active set being in this UE.It should be appreciated that the measurement that UE902 carries out can cause mobility event, wherein when forwarding this mobility event to Serving RNC, it is possible to make Serving RNC change the active set of this UE.For example, it is possible to by the mode identical with version 8, version 9 and version 10, be arranged in square frame 932 measurement (it has and does not have compact model (CM)) undertaken by UE902.After downlink pilot signal being monitored a period of time in square frame 932, UE902 sends channel feedback (square frame 934) on uplink carrier UL_F1.Such as, this channel feedback may include that based on the measurement undertaken by UE902 in square frame 932, the average signal strength of each in the downlink pilot signal monitored and/or the average pilot SIR of each in the downlink pilot signal monitored.In Fig. 9 A, it can be assumed that the sector 1906 of RAN904 and sector 2908 receive channel feedback from UE902 on uplink carrier UL_F1.Such as, sector 1906 and sector 2908 can be among the active set of UL_F1, it means that the ul transmissions from UE902, on UL_F1, is monitored by sector 1906 and sector 2908 actively.Therefore, when, in square frame 934, when UE902 sends signal on UL_F1, sector 1906 and sector 2908 all receive transmission.Now, channel feedback is transmitted to Serving RNC 903 by sector 1906 and each in sector 2908, and if necessary, Serving RNC 903 updates the active set of UE902 (square frame 936,938) based on this channel feedback.
Although Fig. 9 A is not explicitly illustrated, but UE902 can also monitor on DL_F1 and/or DL_F2 and measure the downlink transmission from sector 1906 and sector 2908, to provide physical layer feedback (CQI (CQI) and/or H-ARQ information), described physical layer feedback can at the reverse link physical layer channel of UL_F1 (such as, HS-DPCCH) send to sector 1906 and sector 2908 on, sector 1906 and sector 2908 use the data rate from each sector and/or transmitted power level that this physical layer feedback adjusts on DL_F1 and/or DL_F2 subsequently.
The aspect of Fig. 9 A discussed above, distributes single uplink carrier UL_F1 to UE902, sends physical layer feedback to serving sector 1906 and serving sector 2908 on this uplink carrier UL_F1.Therefore, based on from single uplink carrier UL_F1(namely, " grappling " carrier wave) physical layer feedback, in the meaning that each carrier wave from each sector is controlled, for power control aspect, downlink carrier DL_F1 and/or DL_F2 from sector 1906 and sector 2908 is the part of same " carrier wave set ".In each side of Fig. 9 B next described, distribute multiple uplink carriers to UE902, described uplink carrier provides feedback.In this version, each uplink carrier distributing to UE can be associated with different carrier group.
Fig. 9 B according to an aspect of the present invention, depicts the another kind of method being sent data by multiple serving sectors to UE902.Referring to Fig. 9 B, square frame 910-924 as described by Fig. 9 A, therefore for brevity, will not be described further.
Referring to Fig. 9 B, square frame 924 adds sector 2908 as after other serving sector, sector 2908 indicates UE902 that one or more downlink carriers (or frequency) DL_F1 and DL_F2 is monitored, receive Mobile Termination data (square frame 940) on the one or more downlink carrier (or frequency) DL_F1 and DL_F2 from sector 2908, it is similar to the square frame 926 in Fig. 9 A.But, different from Fig. 9 A, in square frame 940, the second uplink carrier (UL_F2) is also distributed to UE902 in sector 2908.
Referring to Fig. 9 B, sector 2908 begins at and sends signal (square frame 942) to UE on downlink carrier DL_F1 and/or DL_F2, and sector 1906 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, the downlink pilot signal of each sector in its active set is monitored and/or the downlink pilot signal from home cell or sector is monitored by UE902, in order to identify but without the community in the active set being in this UE902.It should be appreciated that the measurement that UE902 carries out can cause mobility event, wherein when forwarding this mobility event to Serving RNC 903, Serving RNC 903 is made to change the active set of UE902.For example, it is possible to by the mode identical with version 8, version 9 and version 10, be arranged in square frame 946 measurement (it has and does not have compact model (CM)) undertaken by UE902.
As discussed briefly above, each in uplink carrier UL_F1 and UL_F2 can be associated with the carrier wave set of the active set of their own and their own, wherein each carrier wave set is corresponding with one group of sector, wherein being based in part on from uplink carrier UL_F1 or UL_F2 physical layer feedback provided, down-link transmitting power and/or data rate to this group sector are controlled.When there are two or more uplink carriers, as in figures 9 b and 9, each carrier wave set is configured (that is, by the Serving RNC 903 to the network that sector 1906 and sector 2908 are controlled) by network so that is positioned at the carrier wave among same carrier wave set and has similar overlay area.Such as, the carrier wave that identical serving sector is supported can collectively constitute a part for a carrier wave set.In figures 9 b and 9, owing to two uplink carrier UL_F1 and UL_F2 in DCHSUPA are respectively provided with the active set of themselves, therefore there are two carrier wave set (unless using anchor carrier on uplink).
In one example, each in two uplink carrier UL_F1 and UL_F2 can the carrier wave set (data rate and/or transmitting power are modified) of independently controlled each of which.Or, in uplink carrier can include " grappling " carrier wave, and another uplink carrier at least includes the carrier wave matched with auxiliary uplink carrier.Can the downlink carrier of another " pairing " be put in any one in the two carrier wave set.Can have the mode of similar handoff boundary by the carrier wave in same carrier wave set and realize packet.
The measurement to downlink pilot signal undertaken by UE902 in square frame 946 can trigger " mobility event ".For mobility, in anchor carrier version, each mobility event (or for each triggering that potential active set changes, for instance, soft handover, to the conversion of new or different Serving cell, the going offline of old Serving cell) this anchor carrier (UL_F1) can be based on.In this case, auxiliary uplink carrier (UL_F2) being considered as " not using ", event 2x measures for these.The ability that auxiliary uplink carrier is measured by UE902 when not using compact model (CM), it is possible to be conducive to this frequency Shang Xin community is identified.For example, it is assumed that UL_F1 is uplink anchor carrier, along with UE902 moves to sector 2908 from sector 1906, only when the DL_F2 of sector 1906 adds in the active set of UL_F2, just can increase the service from the DL_F1 on sector 1906.When UL_F1 is anchor carrier, new mobility event can also promote UE902 to report DL_F2 intensity.
In the version substituted, it not that the channel quality of the community being solely based in grappling frequency triggers the report from UE902, the channel quality being also based on recording in other an active non-anchor frequency triggers the report from UE902, thus existing when lack of balance load helpful in a network.
In the version of another replacement, replace via single anchor carrier, it is possible to via realizing mobility event management on the basis of each carrier wave set.As it has been described above, each carrier wave set maintains active set.In one example, it is assumed that UE maintains two independent active sets (a corresponding respective carrier wave set of active set), it is possible to implement the search to two carrier wave set when not using CM.In this case, when UE902 is moving away sector 2908 and is going to sector 1906, (replace when the DL_F2 on sector 1906 adds the active set of UL_F2 to) when the DL_F1 on sector 1906 adds the active set on UL_F1 to, it is possible to increase from the service on the DL_F1 of sector 1906.This causes the bigger extension serviced of the DL_F1 from sector 1906.This option is likely to need DC-HSUPA to support.In addition, can pass through to allow each uplink carrier in the uplink carrier (UL_F1, UL_F2) of pairing individually carries the HS-DPCCH of each downlink carrier (DL_F1, DL_F2), the problem alleviating physical layer feedback channel in up-link.
As described in more detail in realized example referring to Figure 10 A-10G exemplary, sector 2908 can at single downlink carrier (DL_F1 or DL_F2, but it not being both) upper and given UE902 communicates, or UE902 that can be upper and given two carrier waves (DL_F1 and DL_F2) concomitantly communicates.Can by downlink carrier DL_F1 and the DL_F2(in sector 2908 if present) be considered as basic with downlink carrier DL_F1 and DL_F2(in sector 1906 if present) similar mode configures, except except the different serving sectors transmission of given UE.
Return to Fig. 9 B, after downlink pilot signal is monitored a period of time by square frame 946, given UE902 sends channel feedback (square frame 948) on uplink carrier UL_F1 to sector 1906, also sends channel feedback (square frame 950) individually on uplink carrier UL_F2 to sector 2908.Therefore, the version shown in Fig. 9 B is corresponding with non-anchor carrier version, thus individually the carrier wave set of UL_F1 and UL_F2 being controlled.Although Fig. 9 B is shown without, but a kind of alternative method of the method is anchor carrier version (below it being described more fully), pass through the method, single uplink carrier (UL_F1 or UL_F2) can be used to provide channel feedback (i.e., it is possible to sending the measured pilot tone of two carrier wave set in anchor carrier) for two carrier wave set.In one example, the first carrier group of uplink carrier UL_F1 and downlink carrier DL_F1 and/or DL_F2 at least included in sector 1906 is associated, and second carrier wave set of uplink carrier UL_F2 and downlink carrier DL_F1 and/or DL_F2 at least included in sector 2908 is associated.In addition, the channel feedback sent in square frame 948 and 950 may include that based on the measurement undertaken by the UE902 given in square frame 946, the average signal strength of each in the downlink pilot signal monitored and/or the average pilot SIR of each in the downlink pilot signal monitored.
Although Fig. 9 B is not explicitly illustrated, but this given UE902 can also monitor on DL_F1 and/or DL_F2 and measure the downlink transmission from sector 1906 and sector 2908, to provide physical layer feedback (such as, CQI (CQI) and/or H-ARQ information), this physical layer feedback can be sent to sector 1906 and sector 2908 on the reverse link physical layer channel (HS-DPCCH) of UL_F1 and/or UL_F2, sector 1906 and sector 2908 use this physical layer feedback to the data rate from each sector adjusting on DL_F1 and/or DL_F2 and/or transmitted power level subsequently.Multiple uplink carrier UL_F1 and UL_F2 can allow this given UE902 that the HS-DPCCH information of the carrier wave in same carrier wave group is encoded, and these information is encoded together, and sends on the uplink carrier corresponding with this carrier wave set.Such as, if UE902 has two downlink carriers (DL_F1 and DL_F2) and two uplink carriers (UL_F1 and UL_F2);HS-DPCCH for the two downlink carrier (DL_F1 and the DL_F2 in sector 1 and/or 2) is encoded on the two uplink carrier by this option.
Return to Fig. 9 B, the sector 1906 of RAN904, on uplink carrier UL_F1, receives channel feedback from given UE902, and this channel feedback is transmitted to Serving RNC, and if necessary, Serving RNC adjusts the active set (square frame 952) of this given UE902 based on this channel feedback.Equally, the sector 2908 of RAN904 is on uplink carrier UL_F2, feedback is received from given UE902, and this channel feedback is transmitted to Serving RNC, and words if necessary, then Serving RNC is based on this channel feedback, adjusts the active set (square frame 954) of this given UE902 for UL_F2.
In addition, each in Fig. 9 A and Fig. 9 B depicts following scene: given UE902 sets up sector 1906 as initial service sector, when entering into the switching area between sector 1906 and sector 2908 or region at this given UE902 after a while, add sector 2908 as another serving sector.One substitute version in, this given UE902 can between sector 1906 and sector 2908 switching area or region in power up simply, in this case, set up both sector 1906 and sector 2908 concurrently, as the serving sector of UE902.
Additionally, the node B being associated with the sector 1906 in Fig. 9 A and Fig. 9 B and sector 2908, it is possible to there is different transmission power capabilities.Such as, supporting that macrocell, Microcell or picocell can be supported in sector 1906 by the node B of sector 1906, it is compared with the node B supporting sector 2908, it is possible to cause different transmitting power capacity.This transmission power capabilities difference can cause following scene: in this scenario, it is allowed to different service cells operates on different carrier can improve handling capacity.
In the version substituted, as mentioned above, it is substituted in upper transmission of uplink carrier UL_F1 and UL_F2 and feeds back (channel feedback or physical layer feedback) for the independent of two carrier wave set, it is possible in the plurality of uplink carrier is appointed as " grappling " uplink carrier.In this case, for physical layer feedback, can the HS-DPCCH information consolidation that be used for each downlink carrier (DL_F1 and/or DL_F2 from sector 1906, DL_F1 and/or DL_F2 etc. from sector 2908) be encoded in a code word (as in for the version 8 of DCHSDPA or for DCHSDPA together with the version 9 of MIMO and DBDCHSDPA in or in the version 10 of 4CHSDPA), send on grappling uplink carrier subsequently.Should be understood that, if representing multiple carrier wave set to use single anchor carrier, the serving sector being then associated with this anchor carrier can forward this UE to feed back (to other serving sector), or anchor carrier is monitored by each (such as, each carrier wave in the active set of at least this anchor carrier) that can pass through in these carrier waves simultaneously.
Below, the multiple of process providing Fig. 9 A and Fig. 9 B with reference to Figure 10 A-10G realize example.More specifically, each width figure in Figure 10 A-10G depicts the different articulation set can set up between the UE902 of Fig. 9 A-9B from serving sector 1906 and sector 2908.
In Figure 10 A, method according to Fig. 9 A realize example, depict communication system 1000a, wherein, serving sector 1906 is communicated with UE902 by downlink carrier (that is, DL_F1) identical, single with each in serving sector 2908, distributes single uplink carrier (namely to UE902, UL_F1), this single uplink carrier provides the feedback for carrier wave set.Therefore, in the example of Figure 10 A, it does not have use the second downlink carrier DL_F2.Should be understood that, the omission of downlink carrier DL_F2 can fail to support that downlink carrier DL_F2(sector 1906 and sector 2908 are disposed by single carrier frequency rate based on serving sector 1 and/or 2 and realize), or, alternatively, can determine that the load level of downlink carrier DL_F2 is higher than thresholding based on Serving RNC so that be currently disabled for supporting the resource of UE902 on downlink carrier DL_F2.
Referring to Figure 10 A, it is assumed that sector 1906 is corresponding with " master " sector of downlink carrier DL_F1, sector 2908 is corresponding with " auxiliary " serving sector of downlink carrier DL_F1.In aspects of the present invention, each specific downlink carrier can obtain single main serving sector and the support of at least one assistant service sector.Generally, with compared with the assistant service sector of specific downlink carrier, main serving sector is more lasting.Additionally, contrary with assistant service sector, more downlink Mobile Termination data can be directed to main serving sector by RNC.In other example, compared with assistant service sector, main serving sector can associate with the relatively low-load of associated carrier, and/or can have and being more preferably connected of UE902.Downlink carrier DL_F1 in sector 1906 and sector 2908 all carries the unique HS-DSCH that can be monitored by UE902.In this case, by two HS-DSCH on same carrier wave or frequency (that is, DL_F1), it is possible to transmit two unique transmission blocks from sector 1906 and sector 2908 to UE902.In other words, different sectors sends different data (that is, being contrasted, wherein in non-HSDPA agreement, send identical data redundantly in Zone switched) with the soft handover in non-HSDPA agreement in identical carrier wave.Such transmission plan is properly termed as unifrequency double small district HSDPA(SF-DC-HSDPA).It should be appreciated that in the reality infrequently fully using this system is disposed, SF-DC-HSDPA can provide balancing dynamic load.As shown in FIG. 10A, each in main serving sector 1906 and assistant service sector 2908 can to from UE902, the signal that sends on uplink carrier UL_F1 is monitored and receives.
In fig. 1 ob, method according to Fig. 9 A realize example, depict communication system 1000b, wherein, each in serving sector 1906 and serving sector 2908 is communicated with UE902 by single downlink carrier (that is, respectively through DL_F1 and DL_F2), distributes single uplink carrier (namely to UE902, UL_F1), this single uplink carrier provides the feedback for carrier wave set.Therefore, in the example of Figure 10 B, downlink carrier frequency DL_F1 and the DL_F2 that sector 1906 and sector 2908 use respectively can be mutually orthogonal, in order to reduces the interference at UE902 place.Referring to Figure 10 B, it is assumed that the downlink carrier DL_F1 in the sector 1906 and downlink carrier DL_F2 in sector 2908 all carries the unique HS-DSCH that can be monitored by UE902.In this case, by two HS-DSCH on different carrier waves or frequency (that is, DL_F1 and DL_F2), it is possible to transmit two unique transmission blocks from sector 1906 and sector 2908 to UE902.In the exemplary version of Figure 10 B, because serving sector 1906 communicates via DL_F1 and UE902, and serving sector 2908 communicates via DL_F2 and UE902, so both serving sector 1906 and serving sector 2908 are all " host sectors " for their concrete downlink carrier, this is owing to not having subcarrier in Figure 10 B.As shown in Figure 10 B, serving sector 1906 and in serving sector 2908 each can to from UE902, the signal that sends on uplink carrier UL_F1 be monitored and receive, even if serving sector 2908 is not just sending signal on DL_F1.In one example, serving sector 2908 can be overload, and it causes that serving sector 2908 fails to provide downlink support on DL_F1, although remaining able to the feedback as the UE902 sent on the UL_F1 of anchor carrier is decoded.
Additionally, referring to Figure 10 B, in another example, it is assumed that both downlink carrier DL_F1 and DL_F2 are both supported in sector 1906 and sector 2908.But, as an example embodiment that the DL_F2 on the sector 1906 and DL_F1 on sector 2908 is heavy duty, and the DL_F1 on the sector 1906 and DL_F2 on sector 2908 is light load.In this case, from sector 1906, UE902 being serviced on DL_F1, UE902 services from sector 2908 (as shown in Figure 10 B) on DL_F2 will cause that handling capacity increases.It should be appreciated that there is much different scenes, in these scenes, UE902 is carried out service from different sectors by different carrier and can improve the service to UE902.
In fig 1 oc, method according to Fig. 9 B realize example, depict communication system 1000c, wherein, each in serving sector 1906 and serving sector 2908 is by single (and different) downlink carrier (namely, respectively DL_F1 and DL_F2) communicate with UE902, two uplink carriers are distributed (namely to UE902, UL_F1 and UL_F2), the two uplink carrier provide for each carrier wave set (namely, at least include the first carrier group of the DL_F2 of sector 2908, and at least include second carrier wave set of the DL_F1 of sector 1906) feedback.The example of Figure 10 C is similar to above with reference to the example described by Figure 10 B, except Figure 10 C provides two uplink carriers (UL_F1 and UL_F2) to UE902, outside replacing the single uplink carrier (UL_F1) in Figure 10 B, it forms two unique carrier wave set for UE902 and active set.Correspondingly, two uplink carriers (UL_F1 and UL_F2) allow UE902 respectively through UL_F1 and UL_F2, two unique carrier wave set to be individually controlled, described by Fig. 9 B.Such as, uplink carrier UL_F1 can provide the feedback being associated with first carrier group (it at least includes the downlink carrier DL_F1 on sector 1906), and uplink carrier UL_F2 can provide the feedback being associated with the second carrier wave set (it at least includes the downlink carrier DL_F2 on sector 2908).
Or, referring to Figure 10 C, even if providing two uplink carrier UL_F1 and UL_F2 to UE902, still the feedback for two carrier wave set can be provided by single anchor carrier (UL_F1 or UL_F2).In this case, sector 1906 and sector 2908 are both in the active set of this anchor carrier so that the feedback in this anchor carrier all will be carried out suitable decoding by two sectors.Due to itself and the similarity of Figure 10 B, therefore for brevity, further describing Figure 10 C will be omitted.
