Fig. 2 is the example for estimating CPICH Common Pilot Channel (CPICH) signal intensity.Such as this may be used for calculating channel Quality instruction (CQI).

CQI may refer to show the index of downlink data transfer rate, preferred with transport block size, modulation type and UE The form of parallel encoding quantity represent.CQI can be by estimating CPICH Common Pilot Channel (CPICH) signal intensity and interference/make an uproar Acoustical power, the composite index then mapped that in the predefined table consistent with the block error rate designed calculates.

At MP-HSDPA, make use of interference to avoid with the CQI that can affect during Signal Enhanced Technology at UE and measure process.

CQI can be the optimum capacity being received HS-PDSCH data by UE under certain particular measurement condition and the probability of error Time measure and report tabular value.

Assume that the particular value of HS-PDSCH power of overall reception is to carry out CQI measurement.Because when HS-PDSCH does not has Need when occurring in the received signal to report CQI, so the power of downlink pilot CPICH can be as a reference to obtain To it is desirable that what.In CQI measurement, the incorrect use with reference to CPICH power can cause over-evaluating or underestimating CQI, and this is just The loss of UE handling capacity or too much error in data may be caused.For unicast, can make as follows with reference to CPICH power With:

P_HSPDSCH=P_CICH+ Γ+Δ (dB)

Wherein P_HSPDSCHAnd P_CPICHIt is HS-PDSCH and CPICH power respectively.Measure power excursion Γ to be believed by high level Number notice, reference power regulation Δ can be in the parameter defined in suitable CQI table.

During MP-HSDPA operates, such as HS-SFN mode, can comprise more than two transmission letters in the data transmission Number.Fig. 2 shows and estimates the citing with reference to CPICH power, and wherein merging process can be summation.Such as, UE is from difference service The CPICH signal that community receives can merge, as they are by same process path HS-PDSCH.200, UE can be from One or more cell received signal that associating transmission includes.Permissible from the CPICH combining the community that transmission includes Utilize different scrambling codes and HS-PDSCH cannot.The signal received can be split, and the most each signal can be by independent DIGEN Descramble according to themselves scrambler, such as, 210 and 215.Such as, this may be used for estimating each of single CPICH signal Individual.220 and 225, the CPICH signal after descrambling can be spread.If they be any be applied to HS-PDSCH across community Precoding weights, then identical precoding weights can be applied to CPICH signal with 235 230.Then permissible 240 Merging CPICH signal provides CPICH power to estimate.Such as, UE can be associating transfer mode, for the purpose of CQI, The HS-PDSCH power summation that assume that reception is as follows:

P_HSPDSCH=P_CPICH+ Γ+Δ (dB)

Wherein P_CPICHExpression, can be according to good from the power of the CPICH of the merging of the cell receiver combined transmission As, identical scrambler is applied to transmitter weights CPICH is the same determines P_CPICH。

Can also be by estimating that the CPICH power utilizing of first service community can be used at UE with reference to CPICH power Channel estimation results calculate.Such as,Can be the channel coefficients of the estimation of the symbol level of the first community,Can be The channel coefficients of the estimation of the symbol level of second service community.Can estimate by following equation with reference to CPICH power:

$P_{\mathrm{CPICH}}={\hat{P}}_{\mathrm{CPICH}1}\frac{{|w_1\widehat{h_1}+w_2\widehat{h_2}|}^2}{{\left|w_1\widehat{h_1}\right|}^2}$

WhereinCan be the reception power of the CPICH coming from first service community estimated, and w₁And w₂It is If employ any when cell transmission diversity technique across cell precoding weights.

In another embodiment, CQI can be defined as when UE can be configured to associating transfer mode.In order to The purpose of CQI, UE assume that the HS-PDSCH power summation of reception is:

P_HSPDSCH=P_CPICH+ Γ+Δ (dB)

Wherein P_CPICHExpression, can be with first from the power of the CPICH of the merging of the cell receiver combined transmission The reception power of the CPICH of Serving cell proportionally determines P_CPICH.In order to make P_CPICHWith P_PDSCHProportional, proportionality coefficient Can determining across cell precoding weights by channel estimation results and two Serving cells.

Can be in the way of using other various definitions with reference to CPICH power.For example, it is possible to individually estimate from difference little The CPICH power in district, can be their summation with reference to CPICH power:

$P_{\mathrm{CPICH}}={\hat{P}}_{\mathrm{CPICH}1}+{\hat{P}}_{\mathrm{CPICH}2}$

In another embodiment, can be with origin from the CPICH of the Serving cell combined in transmission with reference to CPICH power The maximum of power defines:

$P_{\mathrm{CPICH}}=\max ({\hat{P}}_{\mathrm{CPICH}1},{\hat{P}}_{\mathrm{CPICH}2})$

In another embodiment, can be with origin from the meansigma methods of the CPICH power of Serving cell with reference to CPICH power Define:

$P_{\mathrm{CPICH}}=({\hat{P}}_{\mathrm{CPICH}1}+{\hat{P}}_{\mathrm{CPICH}2})/2$

In another embodiment, can determine from the CPICH power of first service community with origin with reference to CPICH power Justice:

$P_{\mathrm{CPICH}}={\hat{P}}_{\mathrm{CPICH}1}$

In some scenes, only relevant to Serving cell channel quality information is for Node B report HS-PDSCH Data dispatch is necessary.Although the dispatch coordination between different districts likely can be carried out by multipoint transmission mode, example Such as HS-DDTx and HS-SFN, but the signal of UE receptor and disturbed condition may be dynamically with the scheduling decisions at node B Function and change.The CQI information of specific Transmission Time Interval (TTI) known at NodeB scheduler can allow to use association UE handling capacity is optimized with scheduling.Although can make what NodeB scheduler knows via the interactive control information between community Time and how there is cooperative scheduling event, but from the estimation of report, successfully predict that current CQI may require UE and reports By DTXed or combine and transmit the impact on disturbed condition that causes at UE.

In one embodiment, the UE CQI field from its interfered cell administered via HS-PDSCH can be allowed Report CPICH power.Utilizing the information that this is reported, the factor that node B can change noise source is included and root The CQI that it was reported revises accordingly, if node B take part in cooperative scheduling event in TTI on the horizon.

In order to realize this embodiment, CQI format allows the CPICH power of administration interfered cell to be incorporated into CQI meter In calculation.Such as, a kind of method calculating auxiliary CQI can include the reception that the scrambler used by administration interfered cell processed Signal and the channelization codes of CPICH extract the CPICH component in signal.CPICH signal power P_CPICH,intCan be estimated Meter is used for administering interfered cell.Amount to jamming power P_intCan estimate at UE (to include that administering interfered cell and not including services little District), this may be identical with estimate for regular CQI.CPICH SIR=P can be estimated_CPICH,int/P_int.Auxiliary CQI can lead to Cross the mapping relations searched between CQI and the CPICH SIR drawn from predefined mapping table or by predefined public affairs Formula obtains.If employing B class CQI format, it is possible to use additional PCI field indicates activity in its two-bit field Which community in group is administration interfered cell, and which community can support 4 communities.

Upon receipt of auxiliary CQI, by compared with the conventional CQI that it receives, node B can drive interfered cell CPICH power is associated with the CPICH power of first service community.Then this information may be used for by obtaining more accurately CQI optimizes the scheduling of node B.

According to unconfined observation interval, auxiliary CQI can also be defined as the highest of the administration interfered cell of UE report List auxiliary CQI value, as being used for HS-PDSCH transmission under the identical noise run into Serving cell and disturbed condition. In order to assist the purpose of CQI, UE assume that the HS-PDSCH power summation of reception is:

P_HSPDSCH=P_CPICH,int+ Γ+Δ (dB)

Wherein P_CPICH,intThe CPICH power that administration interfered cell is used can be represented.At the term for multicast communication In, finger specific cell can be fixed in administration interfered cell, and is referred to as second service community.

In another embodiment, the reporting format of auxiliary CQI can be revised as introducing new look-up table completely, this table There is one group of new tabular value, define the relevant CPICH merit associated to the CPICH power of first service community of interfered cell Rate.One of this table is exemplified below:

Table 1 assists CQI table

Auxiliary CQI of the relative power of the CPICH of report interfered cell can be described as follows:

According to unconfined observation interval, UE can report CPICH power and the first service community of administration interfered cell The ratio of CPICH power.Auxiliary CQI being mapped to power ratio can be defined in table 1.

Fig. 3 can be used for the example that the CQI of network scheduling estimates.This can pass through expected interference and/or signal rank Change be used for, such as provide more accurately CQI calculate.Such as, Fig. 3 shows when network is avoided or signal to disturb The purpose strengthened may be used for when have employed cooperative scheduling correcting the citing that CQI estimates.

It is assumed for purposes of illustration that 245, in (n-2) individual Transmission Time Interval (TTI) computation of Period CQI of 280 (n-2), wherein HS-PDSCH is transmitted to another UE in interfered cell 255.Current UE can be taken by interfered cell 255 from it Business community 260 receives and produces interference.As indicated by arrows 250, the CQI (n-2) when 245 is used for the tune that TTI is spaced the 265 of n+2 During the transmission that degree and network decision come coordinates interference community by closing its HS-PDSCH transmission, CQI (n-2) middle finger 245 The transport block size shown is probably to be underestimated, because interference is not worked.It is similar to, over-evaluates situation it may happen that in 270 CQI (n-1), in the interference occurred there is not calculated in.

If CQI calculates as the CQI (n+3) at 275 by averagely completing across TTI border, node B is come Say that execution Optimized Operation is also likely to be highly difficult.

According to embodiment of the present disclosure, it is provided that technology is to be spaced by compensating from second at identical TTI at UE Appearance/the disappearance of the interference signal of community, such as interfered cell 255 estimates multiple CQI.If multi-cell signals can be used Folding, CQI calculates can consider this technology, and the capacity that reporting channel can be supported.

These CQI value can be reported to network via uplink feedback channel HS-DPCCH, thus can perform The network scheduling optimized.

Following paragraph illustrates how to calculate CQI for MP-HSDPA technology by open.

In one example, perform CQI calculating and may be used for HS-DDT.The main target of HS-DDTx technology is by association Interference is provided to avoid with network scheduling.Therefore, there are on the basis of TTI two groups of CQI estimated and report simultaneously be probably Profit, one of which report considers the channel quality that interference is avoided, and another group does not accounts for.These two groups of CQI can distinguish table It is shown as CQI_IAAnd CQI_NA, wherein IA represents that interference is avoided, and NA represents not interfere with and avoids.

In Fig. 3, during the TTI of interference, n-th TTI of (n-2) individual TTI or 285 of such as 280, it will usually send out Raw CQI_NACalculating.Such as, CQI is calculated_NAMay include that

1. by using the channelization codes of the scrambler used by Serving cell and CPICH to process the signal of reception to extract CPICH component in the signal received

2. estimate CPICH signal power P_CPICH

3. estimate jamming power P from every other community_int

4. estimate CPICH SIR=P_CPICH/P_int

5. by the mapping relations searched in predefined mapping table between CQI and the CPICH SIR obtained or pass through Predefined formula obtains CQI, and this predefined formula can be in conjunction with multiple factors (such as HOM and utilize senior receptor) Compensate to provide CQI more accurately to calculate.

As the CQI calculating identical TTI_IATime, some interference components produced from co-interfere community may need to remove, because of For having been carried out measuring during the TTI of interference.Such as, in one embodiment, it is for assisting as HS-PDSCH During with the DTXed of interfered cell, can estimate by the jamming power of this HS-PDSCH channel contribution, and estimate from CPICH SIR Meter removes it.Calculate CQI_IAMay include that

1. by using the channelization codes of the scrambler used by Serving cell and CPICH to process the signal of reception to extract CPICH component in the signal received

2. estimate CPICH signal power P_CPICH

3. estimate jamming power P from every other community_int

4. by using the channelization codes of the scrambler used by interfered cell and CPICH to process the signal of reception to extract The CPICH component that interfered cell is transmitted

5. estimate CPICH signal power P from interfered cell_CPICH,int

6. compensate P_CPICH,intTo obtain HS-PDSCH power from interfered cell

P_HS-DPSCH,int=P_CPICH,int(G_HS-DPSCH/G_CPICH)²

Wherein G_HS-DPSCH/G_CPICHIt is the ratio of the proportional factor of HS-DPSCH and CPICH for interfered cell, Assume that UE is known to this ratio.Otherwise can estimate this ratio.

7. the definition remainder factor, R_res, its reflection is relative to applying the different descramblings and channel used from transmitter terminal The dump power grade of the signal after change code.This parameter can be the spreading factor and the letter of channelization codes used Number.This function can obtain from theory analysis or emulation.All it is used for sending UE's at not every channelization codes In the case of HS-DPSCH transmission, can calculate according to the part actually used for this UE or estimate R_res。

8. calculating jamming power summation by removing the interference power that brings of HS-PSCH, it is probably side-play amount:

P'_int=P_int-P_HS-DPSCH,intR_res

9. the CPICH SIR of estimation amendment:

CPICH SIR=P_CPICH/P'_int

10. by the mapping relations searched in predefined mapping table between CQI and the CPICH SIR obtained or pass through Predefined formula obtains CQI_IA。

If HS-SCCH is also that DTXed(transmits in co-interfere community), 6 to 8(is illustrated above) can also answer Use in the HS-SCCH power of interfered cell.Notice different values R_resMay use or not use.

P_CPICHCan also represent with dB or linear graduation according to every chip energy (Ec) or energy per bit (Eb). Noise power can also represent according to noise spectral power density (Ioc).

(n+2) individual TTI of (n-1) individual TTI or 265 of 290 in non-interference TTI, such as Fig. 3, calculates CQI_IA Can be simple, because may be eliminated from signal by the component of signal of DTXed.On the other hand, calculate CQI_IAMay need revise jamming power, the step for may follow after said method the 10th step；But, the 8th step may Needs are revised as:

8. calculating jamming power summation by adding the interference power that brings of HS-PSCH, it is probably side-play amount:

P'_int=P_int+P_HS-DPSCH,intR_res

Notice that the power in said process is estimated, either be still used for disturbing for signal, can be by by one Data in individual TTI interval are averaged and obtain.

Fig. 4 is the citing that CQI estimates when TTI border is uneven.Asynchronous on the TTI border of Liang Ge community, i.e. in the presence of Between in the case of skew, averagely can the TTI border of and then interfered cell, as shown in Figure 4.Such as, Fig. 4 shows TTI limit CQI time may not align in boundary estimates.As shown in Figure 4,295, TTI(N+1) occur, this TTI can with from interfered cell The HS-PDSCH300 alignment of 306.But, do not have and HS-from the TTI border of the HS-PDSCH305 of Serving cell 307 transmission PDSCH300 aligns.310, CQI(n+1 can be produced).

In one example, CQI calculates can be that MF performs.In MF operates, the community that multicast communication includes can To be defined as the first community and multiple second community or multipoint cell.CQI can be that each community prepares.This Sample, it may be necessary to UE estimates N number of CQI, wherein N be configuration can join together for while downlink transmission The quantity of community.Alternatively, N can be the quantity of small active area.Each of CQI can be by application by turning down mutually The scrambler of oneself that district uses calculates.

In one example, CQI calculates can be that HS-SFN performs.Fig. 5 shows the example that HS-SFN transmits.Example As, Fig. 5 shows that HS-SFN transmits, and the signal that wherein interfered cell is transmitted at (n-1), (n+2) and (n+4) individual TTI uses The signal with identical scrambler identical with Serving cell.As it is shown in figure 5, HS-PDSCH325, HS-PDSCH330 and HS- PDSCH335 can be transmitted by interfered cell 315, it is possible to uses the signal identical with the transmission that Serving cell 320 transmits and disturbs Code.

In HS-SFN, network dispatcher can use identical scrambler to transmit identical data by allowing interfered cell Coordinates interference community, and it is more than terminating the data transmission of interfered cell.This can avoid interference and can strengthen and send UE to HSDPA data transmission signal intensity.Optimum network scheduling is it may be desirable to two groups of CQI estimate: CQI_SERepresent that interference is little District may be used for the channel quality in the case of signal strengthens, and CQI_INTIn the case of representing that interfered cell is probably interference Channel quality.The difference of the signal condition according to current TTI, they can calculate distinctively.

During interference TTI, such as (n-2) individual TTI or the n-th TTI in Fig. 5, can directly calculate CQI_INT.Example As, it is possible to use the traditional method calculating CQI calculates CQI_INT。

Calculate CQI_SETime, signal and jamming power may be required for being compensated considering that interference is avoided and Signal Enhanced Technology The fact that all used.In one example, following steps can be performed:

1. by using the channelization codes of the scrambler used by Serving cell and CPICH to process the signal of reception to extract CPICH component in the signal received

2. estimate CPICH signal power P_CPICH

3. estimate jamming power P from other communities_int

4. by using the channelization codes of the scrambler used by interfered cell and CPICH to process the signal of reception to extract The CPICH component that interfered cell is transmitted

5. estimate CPICH signal power P from interfered cell_CPICH,int

6. compensate P_CPICH,intTo obtain HS-PDSCH power from interfered cell

P_HS-DPSCH,int=P_CPICH,int(G_HS-DPSCH/G_CPICH)²

Wherein G_HS-DPSCH/G_CPICHIt is the ratio of the proportional factor of HS-DPSCH and CPICH for interfered cell, Assume that UE is known to this ratio.Otherwise can estimate this ratio.

7. the definition remainder factor, R_res, its reflection is relative to applying the different descramblings and channel used from transmitter terminal The dump power grade of the signal after change code.This parameter can be the spreading factor and the letter of channelization codes used Number.This function can obtain from theory analysis or emulation.All it is used for sending UE's at not every channelization codes In the case of HS-DPSCH transmission, can calculate according to the part actually used for this UE or estimate R_res。

8., by removing the power that interference HS-PSCH brings, jamming power summation can be side-play amount:

P'_int=P_int-P_HS-DPSCH,intR_res

9.CPICH power can be compensated by equation below

P'_CPICH=P_CPICH+P_CPICH,int

10. the CPICH SIR of amendment:

CPICH SIR=P'_CHIPCH/P'_int

11. by the mapping relations searched between CQI and the CPICH SIR obtained in predefined mapping table or pass through Predefined formula can obtain CQI_SE, similar with conventional situation.

CPICH power in step 9 can compensate in many ways.Such as, the CPICH power in step 9 can be by Following equation compensates:

${P^{\′}}_{\mathrm{CPICH}}=(1+{\left|\frac{\widehat{h_2}}{\widehat{h_1}}\right|}^2)P_{\mathrm{CPICH}}$ Equation 1

WhereinWithCan be the channel estimation results of service and interfered cell respectively.

In another is illustrated, the CPICH power in step 9 can be compensated by following equation:

WhereinWithRespectively be service and interfered cell HS-PSCH with The power ratio of CPICH.

In another is illustrated, the CPICH power in step 9 can be compensated by following equation:

${P^{\′}}_{\mathrm{CPICH}}=(1+{\left|\frac{\widehat{h_2}{\mathrm{\β}}_2}{\widehat{h_1}{\mathrm{\β}}_1}\right|}^2)P_{\mathrm{CPICH}}$

During the TTI of non-interference, such as (n-1) the individual TTI or (n+2) individual TTI in Fig. 5, can calculate CQI_INT.For example, it is possible to calculate CQI by following manner_INT。

1. by using the channelization codes of the scrambler used by Serving cell and CPICH to process the signal of reception

2. estimate CPICH signal power P_CPICH

3. estimate jamming power P from other communities_int

4. by using the channelization codes of the scrambler used by interfered cell and CPICH to process the signal of reception

5. estimate CPICH signal power P from interfered cell_CPICH,int

6. compensate P_CPICH,intTo obtain HS-PDSCH power from interfered cell

P_HS-DPSCH,int=P_CPICH,int(G_HS-DPSCH/G_CPICH)²

Wherein G_HS-DPSCH/G_CPICHIt is the ratio of the proportional factor of HS-DPSCH and CPICH for interfered cell, Assume that UE is known to this ratio.Otherwise can estimate this ratio.

7. the definition remainder factor, R_res, its reflection is relative to applying the different descramblings and channel used from transmitter terminal The dump power grade of the signal after change code.All it is used for sending to the HS-DPSCH of UE at not every channelization codes In the case of transmission, can calculate according to the part actually used for this UE or estimate R_res。

8., by adding the power that interference HS-PSCH brings, jamming power summation can be side-play amount:

P'_int=P_int+P_HS-DPSCH,intR_res

9. the CPICH SIR of estimation amendment:

CPICH SIR=P_CPICH/P'_int

10. by the mapping relations searched in predefined mapping table between CQI and the CPICH SIR obtained or pass through Predefined formula can obtain CQI_INT。

CQI can be calculated by following steps_SE:

1. by using the channelization codes of the scrambler used by Serving cell and CPICH to process the signal of reception to extract CPICH component in the signal received

2. estimate CPICH signal power P_CPICH

3. estimate jamming power P from other communities_int

4. by using the channelization codes of the scrambler used by interfered cell and CPICH to process the signal of reception to extract The CPICH component that interfered cell is transmitted

5. estimate CPICH signal power P from interfered cell_CPICH,int

6. compensate CPICH power by following equation:

Equation 1-3 as implied above can also be used to calculate CPICH.

7. the CPICH SIR of estimation amendment:

CPICH SIR=P'_CHIPCH/P'_int

8. by the mapping relations searched in predefined mapping table between CQI and the CPICH SIR obtained or pass through Predefined formula can obtain CQI_SE。

The method of TTI boundary alignment described here average signal/jamming power simultaneously can also be applied to employ HS- The situation of SFN.

In one example, CQI calculates can be that DSS performs.In the MP-HSDPA that make use of DSS, Serving cell Can switch between Liang Ge community (or possibly more than two).Because community can a time may be to The mode of operation that UE transmits, the concept for two groups of CQI of IA and NA of HS-DDTx still can use.For example, it is possible to pass through Following process described here calculates CQI_IAAnd CQI_NA.Because interfered cell can also be considered as one of Serving cell, May need to estimate a pair additional CQI at UE_IAAnd CQI_NA, such as by using the scrambler relevant to second service community.

The distinct methods embodiment of calculating CQI set forth above sums up, and UE may need to estimate two kinds CQI, and report to network on the basis of each TTI: a much higher value activating MP-HSDPA, another does not activate MP- The lower value of HSDPA.If it is required, UE may need expected interference or level of signal change, to obtain the correct of corresponding CQI Estimation.The former is referred to as, and ' senior CQI ', the latter is referred to as that ' rudimentary CQI ', they can be defined as when UE is configured to place Discussed such as paragraphs below when MP transmission mode:

For senior CQI, according to unconfined observation interval, UE can report the highest tabulated CQI value, in order to have biography Defeated block size, HS-PDSCH group/cording quantity and the single HS-DSCH subframe with report or rudimentary modulation format corresponding for CQI Can be received with transmission block bit error rate probability, this transmission block bit error rate probability is ending at the 3 slot reference cycles of 1 time slot not More than 0.1, this 1 time slot is before first time slot that the CQI value reported is transmitted starts.This assume that the MP transmission of configuration Can carry out in observation interval.If measure during observation interval CQI, the MP configured at this observation interval be transmitted without into OK, UE can CQI measure in expected interference or the change of signal rank, as employ configuration MP transmission.

For rudimentary CQI, according to unconfined observation interval, UE can report the highest tabulated CQI value, in order to have biography Defeated block size, HS-PDSCH group/cording quantity and the single HS-DSCH subframe with report or rudimentary modulation format corresponding for CQI Can be received with transmission block bit error rate probability, this transmission block bit error rate probability is ending at the 3 slot reference cycles of 1 time slot not More than 0.1, this 1 time slot is before first time slot that the CQI value reported is transmitted starts.This assume that the MP transmission of configuration Observation interval is not carried out.If measuring CQI during observation interval, in the MP transmission that this observation interval is configured, UE can CQI measure in expected interference or the change of signal rank, as configure MP be transmitted without carrying out.

In a following embodiment, employ term " community 1 " and " community 2 ".But, the label of community 1 and 2 Cannot distinguish between whether this community is the first or second community.Such as, community 1 can be first service community, and community 2 can be Second service community.It addition, community 2 can be first service community and community 1 is second service community.And, other names Can also be associated in community 1 and community 2, and need not distinguish.

Fig. 6 is the example combining transmission when configuring and launch diversity with global precoding.

Many transmission (MP-HSDPA) technology described here can improve the UE capacity at cell edge.Such as, as biography A crew-served part between the defeated multiple communities included, the precoding weights of the multiple antennas being applied to each website can With by combined optimization.It addition, the global precoding across multiple communities also be likely used for further performance enhancement.

The example how configuring and designing precoding weights in MP-HSDPA environment provides in following paragraph.

In one example, can perform across cell precoding right-value optimization.Out of phase and possible amplitude adjusted can To be applied to the signal of transmission in each single community to maximize the advantage of multicast communication.These regulations can be by mathematically It is expressed as compound precoding weights.This operation can be referred to as across cell precoding, because optimization may rely on multiple little Coordination between district completes.

In one example, can be associating transmission, such as HS-SFN across cell precoding and perform.Fig. 6 shows and works as The structure chart of the citing system combining transmission when launching diversity with overall precoding can be configured.In figure 6, for each Community, such as transmitter community 350 and transmitter community 355, at least two antenna, such as antenna 340 and 345 can be used for Support that there is the beam shaping in the downlink transmission launching diversity.Antenna 360 can also be used for 365 supporting that wave beam becomes Shape.In order to realize the purpose of multi-antenna emission diversity, it may be necessary to two groups of precoding weights, each group is used for a community.Example As, precoding weight w 11 and w12 can be used for transmitter community 350, and precoding weight w 21 and w22 can be used for launching Machine community 355.Because identical data can be transmitted under MP-HSDPA configures in Liang Ge community, so by each community Application extra phase place or amplitude adjustment in addition to the specific precoding of antenna form the transmitter diversity of another layer can Can be helpful to.Extra phase place or amplitude adjust can be across multiple community associated optimizations, it is possible to by the series connection overall situation Precoding weights realize, as shown in w1 and w2 in Fig. 6.

Represent relevant precoding weights in the form of vectors:

$W=\left[\begin{array}{c}{w}_1\\ w_2\end{array}\right],W^1=\left[\begin{array}{c}{w}_{11}\\ w_{12}\end{array}\right],W^2=\left[\begin{array}{c}{w}_{21}\\ w_{22}\end{array}\right]$

In one example, the standard finding optimum overall precoding vector can be such that

$W_{\mathrm{opt}}=\arg \underset{w}{\max }{W}^H{H}^H\mathrm{HW}$

Wherein H can be cross-site CSI matrix, is joined by the CSI matrix correlation of following equation with each community:

$H=\begin{array}{c}\left[\begin{array}{cc}{H}_1{W}^1& H_2{W}^2\end{array}\right]\end{array}$

In order to notify the precoding weights selected by node B, can use as follows method based on code book:

$W_{11},W_{21}=1/\sqrt{2}$

$w_{12},w_{22}\∈\{\frac{1+j}{\sqrt{2}},\frac{1-j}{\sqrt{2}},\frac{-1+j}{\sqrt{2}},\frac{-1-j}{\sqrt{2}}\}$

Furthermore it is possible to prelist across community by using the code book of code book same as described above or preferable granularity to apply Code, the code book of preferable granularity for example:

$w_1=1/\sqrt{2}$

$w_2\∈\{\frac{e^{\frac{j(n-1)\mathrm{\π}}{8}}}{\sqrt{2}},n=\mathrm{1,2},..,8\}$

Uplink feedback may need transmit three groups CPI: two groups for w to node B₁₂And w₂₂, one group for across Cell precoding coefficient w₂。

Fig. 7 shows have the exemplary plot combining transmission launching diversity.In one embodiment, w₁And w₂Can close And in antenna specific precoding weights, the precoding obtained can be expressed as w₁w₂, w₃w₄.Such configuration is shown in Fig. 7, Fig. 7 show have launch diversity combine transmission schematic diagram.

The value of precoding weights can select from code book:

$w_1=1/\sqrt{2}$

$w_2,w_3,w_4\∈\{\frac{e^{\frac{j(n-1)\mathrm{\π}}{N}}}{\sqrt{2}},n=\mathrm{1,2},..,N\}$

Wherein N can be codebook size.

Fig. 8 is the example of the cross-site transmitting diversity a community with individual antenna.When configuring in one cell During one antenna, can determine as got off across cell precoding weights:

$w_1=1/\sqrt{2}$

$w_2\∈\{\frac{e^{\frac{j(n-1)\mathrm{\π}}{N}}}{\sqrt{2}},n=\mathrm{1,2},..,N\}$

Wherein N can be codebook size.Such as, N can be the calculated integer of power of 2.

Fig. 9 shows that UE is configured to combine during MIMO mode the example of transmission.When UE102 can be configured to MIMO mould During formula, two of which data stream, such as S1 and S2 can be transmitted, from multiple communities combine transmission still can be implemented in In embodiment disclosed herein.Two data streams can transmit from transmitter 350 and transmitter 356, and transmitter 350 can be The transmitter of community 1, transmitter 356 can be the transmitter of community 2.With reference to Fig. 9, although identical data stream S1 and S2 is permissible Transmit from different districts, but the precoding weights of two different groups can be respectively applied to the antenna of each community.

Liang Ge community respective precoding weights can be expressed as:

$W^1=\left[\begin{array}{cc}{w}_{11}^1& w_{12}^1\\ w_{21}^1& w_{22}^1\end{array}\right],W^2=\left[\begin{array}{cc}{w}_{11}^2& w_{12}^2\\ w_{21}^2& w_{22}^2\end{array}\right]$

Combined optimization precoding weights can be carried out according to the specific principle of optimality.Such as, precoding weights can so come Select:

$W=\arg \underset{w}{\max }\mathrm{tr}\left(W^H{H}^H\mathrm{HW}\right)$

Wherein:

$W=\left[\begin{array}{c}{W}^1\\ W^2\end{array}\right],H=\begin{array}{c}\left[\begin{array}{c}{H}_1\\ H_2\end{array}\right]\end{array}$

Wherein H₁And H₂It is the CSI matrix of each community respectively.

For the ease of the method reducing uplink feedback expense, following code book can be used:

${w^1}_{11}=1/\sqrt{2}$

$w_{12}^1,w_{11}^2,w_{12}^2\∈\{\frac{1+j}{\sqrt{2}},\frac{1-j}{\sqrt{2}},\frac{-1+j}{\sqrt{2}},\frac{-1-j}{\sqrt{2}}\}$

May be it needs to be determined that three plural precoding coefficients.Therefore, three groups of precoding control instructions may need to be communicated To node B, preferably select with instruction.Remaining precoding weights, Can so select, i.e. to Amount $\left[\begin{array}{c}{w}_{21}^1\\ w_{22}^1\end{array}\right]$ With $\left[\begin{array}{c}{w}_{11}^1\\ w_{12}^1\end{array}\right]$ It is orthogonal, $\left[\begin{array}{c}{w}_{21}^2\\ w_{22}^2\end{array}\right]$ With $\left[\begin{array}{c}{w}_{11}^2\\ w_{12}^2\end{array}\right]$ Orthogonal.

Figure 10 is the example combining transmission that UE is configured to during MIMO mode have cross-site precoding.An example In, the regulation of cross-site precoding can also be increased in addition to the MIMO precoding of each community.With reference to Figure 10, each community MIMO precoding weights can be expressed as:

$W^1=\left[\begin{array}{cc}{w}_{11}^1& w_{12}^1\\ w_{21}^1& w_{22}^1\end{array}\right],W^2=\left[\begin{array}{cc}{w}_{11}^2& w_{12}^2\\ w_{21}^2& w_{22}^2\end{array}\right]$

Precoding weights can be that single optimization is carried out in each community.In order to determine cross-site precoding weights, it is possible to use Preference rule.Such as, cross-site precoding coefficients can be selected by following rule:

1. $w_1=1/\sqrt{2}$

2.w₂?Middle selection, so

$P={(w_1{H}_1{W}^1+w_2{H}_2{W}^2)(w_1{H}_1{W}^1+w_2{H}_2{W}^2)}^H$

Can maximize.

For above-mentioned transmitter architecture, three groups of PCI need report to prelist for the MIMP of each community to node B: two groups Code weight value, one group for across cell precoding.

In one example, launch diversity to be used together with multithread aggregation scheme.Such as, with reference in Fig. 6 and Figure 10 Shown transmitter architecture can expand in multithread aggregation scheme, and wherein different data streams can be transmitted in different districts, these Data stream can be polymerized to improve downlink throughput at UE.

Figure 11 shows that UE102 is configured to have during TX diversity mode the example of the multithread polymerization of cross-site precoding. As shown in figure 11, different data streams, such as S1 and S2 can be transmitted in different districts, these data streams can UE102 polymerization with Improve downlink throughput.Obtain transmitter configuration may be used for, such as when UE102 be configured in transmitting diversity or During MIMO mode.

Indicate can also using with similar technology disclosed herein of preferred precoding weights.Therefore, three groups of PCI values can Can need to be transmitted to node B to select with instruction UE.

Figure 12 shows that UE is configured to have during MIMO mode the example of the multithread polymerization of cross-site precoding.Such as Figure 12 Shown in, different data streams, such as S1, S2, S3 and S4 can be transmitted in different districts.These data streams can UE102 polymerization with Improve downlink throughput.The transmitter configuration obtained may be used for when UE102 is configured in transmitting diversity or MIMO mould During formula.

Indicate can also using with similar technology disclosed herein of preferred precoding weights.Therefore, three groups of PCI values can Can need to be transmitted to node B to select with instruction UE.

In one example, beam shaping can be executed for across cell precoding right-value optimization.Avoid for interference The concept of HS-DDTx can be expanded to have more intelligent regulation when node B is equipped with multiple antennas for beam shaping. Different from the transmission terminating interfered cell, its less radio-frequency (RF) can intentionally be handled by the scheduler of the node B of interfered cell Wave beam can minimize away from disturbed UE, the so interference to this UE.

Figure 13 shows the example of collaborative beam forming.As shown in figure 13, if known at the node B140b of community 375 Transmission from the node B140a of community 370 sends UE102a to, and it may be intentionally by data dispatch to UE102b. If community 370 and 375 dispatches data all to UE102a and 102d, cross interference may be more notable.In order to help to coordinate wave beam Shaping, UE may need to indicate the Serving cell relative to oneself and the position of oneself of interfered cell.This positional information can To extract from precoding weights.Therefore, UE may need report for the PCI of Serving cell of oneself, and is used for indicating dry Disturb auxiliary PCI of the least preferred precoding values of community.Additionally, it is also possible to need another to assist PCI, to indicate which phase Adjacent cell produces main interference.

These three groups of PCI are necessary for collaborative beam forming operation: one is used for Serving cell, and one is used for disturbing little District, one is used for indicating which neighbor cell can be included in coordination.

In one example, can specify that a new precoding control instruction.As disclosed in this, it is provided that new PCI definition for across cell precoding.Such as, UE can use first service community and second service community to transmit CPICH calculates and will be applied to the preferably vectorial across cell precoding of node B, can prop up under current channel condition to maximize The aggregation transfer block size held.No matter one or two transmission blocks are preferred, and it is preferred that UE transmits signal designation to node B First precoding vectorIt is all enough, because the second precoding vector can be the function of first. When being configured without single ductility limit, about one or two transmission blocks be preferred information can be of CQI Point.Because the preferably first precoding vectorIn the first precoding weightsCan be constant, this can To be sufficiently used for determining the precoding weights of the second community.In UE obtains each TTI of synthesis PCI/CQI report, UE is permissible Calculate the preferred precoding weights of second service community Can obtain from following group:

$w_2^{\mathrm{pref}}\∈\left\{\frac{1+j}{2}\frac{1-j}{2}\frac{-1+j}{2}\frac{-1-j}{2}\right\}$

As defined in following table, precoding weightsMay map to PCI value:

The preferred precoding weights of table 2Mapping to PCI value

Support that collaborative beam forming may need to assist PCI to indicate main interfered cell.Specify new PCI definition Citing can provide UE can use the CPICH sending first service community from adjacent community to, it is possible to finds the strongest Power.The label of this community can be indicated, as defined in following table by auxiliary PCI value:

Table 3 community label is to the mapping of auxiliary PCI value

Community label	PCI value
		Retain	0
1st	1
		2nd	2
3rd	3

Uplink feedback designs

In one example, uplink feedback channel can be designed for MP-HSDPA.As described above, can be at UE Produce multiple CQI with the information enough to network offer to maximize the gain in collaborative multiple community HSDPA transmission. ACK/NACK information can improve due to the downlink transmission while multiple communities.Because in single-frequency uplink A HS-DPCCH physical uplink link feedback channel can be had to use in the transmission of road, HS-DPCCH may need to be arranged to MP-HSDPA.Although for the purpose of simplifying the description, paragraph below may concentrate on double cell operation, but disclosed embodiment can For multiple cell scene.

Table 4 summarises when Liang Ge community is included in MP-HSDPA downlink transmission, HS-DPCCH physical channel CQI and the HARQ-ACK information carried may be needed.

The feedback information of table 4MP-HSDPA

Notice that TTI and subframe can exchange use in disclosure full text.

In one example, HS-DPCCH can be designed for CQI.For the ease of discussing, do not differentiate between and may be used for The CQI type of Feedback Design.Therefore, CQI by CQI1, CQI2 ..., CQIN represents, wherein N can be at HS- DPCCH may need the CQI summation quantity carried.

In one example, the CQI encoding scheme that 3GPP this version of standard is proposed can be re-used, and so can use table 4 and table 5 in already present encoding scheme encode each CQI independently.

Table 5 uses the CQI of already present encoding scheme to encode

CQI type	Encoding scheme	Code word size	Coded-bit
				Non-MIMO CQI	(20,5) Reed Muller coding	20	5
MIMO type A CQI	(20,10) Reed Muller coding	20	10
				MIMO type B CQI	(20,7) Reed Muller coding	20	7

In another example, in the case of non-MIMO, two CQI can be compiled by (20,10) Reed Muller Code device carrys out combined coding.

As described above, multiple realizations may be used for carrying multiple CQI/PCI report in single HS-DPCCH.

In one example, HS-DPCCH frame structure can be used together with single CQI field.Such as, HS-DPCCH thing Reason channel can keep time slot format 0 with SF=256, and wherein CQI field can take two time slots.Multiple CQI can be used Time Division Multiplexing method transmits, and i.e. can they be carried in different subframes.

In a CQI example based on TDM, it is possible to use multiple feedback cycles, such CQI can be divided into Group, each assembling is equipped with the different CQI feedback cycles.Such as, this can be used to reduce feedback overhead.There is rapid feedback week CQI in the group of phase can be used to indicate the channel quality of the small active area transmitting data, and have and feed back more slowly The group in cycle may be used for the purpose of the monitoring of other communities in activity group.Such as, as shown in figure 14, for N=3, CQI1 and CQI2 is divided into one group, has the feedback cycle of 3 subframes, is shown in 380, and 390, and 395, and CQI3 has 6 subframes Feedback cycle, is shown in 385 and 400.

Figure 15 shows the example of double CQI fields HS-DPCCH design with two CQI feedback cycles.HS-DPCCH frame Structure can be designed to double CQI field.Such as, HS-DPCCH physical channel can keep time slot format 1 with SF=128, its Middle CQI field can take a time slot, and double CQI field can be dispensed in subframe.If N=2, CQI can be Transmit in each CQI field in subframe.For N >=2, CQI can be divided into two groups, each is assigned to one In CQI field.If having more than one CQI to need to be assigned in HS-DPCCH in a group, it is possible to use the time-division Multiplexing (TDM).Or one or two feedback cycles can be individually assigned to each CQI group.As shown in figure 15, it is assigned to There is the CQI in the group in rapid feedback cycle and could be used to indicate that the channel of the small active area that may transmit data Quality, and the purpose of the monitoring of other communities that the group with slower feedback cycle can be used in activity group.Such as, CQI1 Can transmit with the feedback cycle of 2 subframes with CQI2, as shown in 405,415,425,430,435,445 and 455.CQI3 Can transmit with the feedback cycle of 4 subframes with CQI4, as shown in 410,420,440 and 450.CQI can also be entered One step is divided into the group of the more than two with multiple relevant feedback cycle.

Figure 16 shows the example of the double-channel code HS-DPCCH design with two CQI feedback cycles.HS- DPCCH frame structure can be designed to double-channel code.Such as, when HS-DPCCH physical channel can keep with SF=256 Gap form 0, wherein CQI field can take two time slots.Further, it is possible to use have the one other channel code of SF=256 with It is easy to new feedback channel, such as 465.If N=2, CQI can transmit on each channelization codes.If N > 2, CQI can be divided into two groups, and each group is assigned in a channelization codes.It is more than if had in a group One CQI needs allocated, it is possible to use Time Division Multiplexing.The concept in above-mentioned multiple CQI feedback cycles can also It is applied to this.As shown in figure 16, double-channel code HS-DPCCH design can be used together with two CQI feedback cycles.Example As, CQI1 and CQI2 can transmit with the feedback cycle of 2 subframes, as shown in 470,475 and 480.CQI3 and CQI4 is permissible Transmit with the feedback cycle of 4 subframes, as shown in 485 and 490.

In another example, multiple CQI can perform together with combined coding.Such as, HS-DPCCH physics letter Road structure and CQI process can keep constant.In order to adapt to the polytype of the CQI needed for MP-HSDPA, additional CQI information can with tradition CQI together with become bag and together with transmit.In other words, there is the chnnel coding of higher coded-bit Two CQI of combined coding can be used for and remain in that 20 identical bit message length simultaneously.Being exemplified below of this application:

● need not encode by (20,5) Reed Muller, non-MIMO CQI message can be by (20,10) chnnel coding Encoding, it includes that two CQI, each CQI are 5 bit lengths.(20,10) chnnel coding can be with 3GPP TS25.212 (title, " multiplexing is identical with in chnnel coding (FDD) ") be type A CQI regulation.It is alternatively possible to use (20,7) channel Coding, wherein 2 bits are allocated for the 2nd CQI.(20,7) chnnel coding can with 3GPP TS25.212 in be type B It is identical that CQI specifies.

● need not encode by (20,7) channel coding schemes, type B CQI message can be compiled by (20,10) chnnel coding Code, it can include that two CQI, 3 bits additionally are assigned to the 2nd CQI.(20,10) chnnel coding can be with 3GPP TS25.212 is the identical of type A CQI regulation.

● its form can be maintained constant for type A CQI and additional CQI information need not be transmitted, or type A CQI can be designed as to be had compared with high code-rate scheme to adapt to more bit.Such as (20,13) chnnel coding can be introduced into The 2nd CQI including 3 bits.

From above-mentioned embodiment, it can be seen that if standard has existed channel coding schemes will multiplexing, Two CQI can be short length.MP-HSDPA is operated, the fact that may be correlated with for two kinds of CQI may consider Ground is enough abundant, because difference is likely to be due to interference and avoids or signal strengthens and brings gain.Shorter in order to effectively utilize 2nd CQI of length, the 2nd CQI can represent the different-format of information:

● it is incremented by with reference to the CQI encoded in same message.Such as, additional bit is likely interpreted as skew. 2nd CQI can be at network by calculating based on offset adjusted the oneth CQI.

● there is the channel quality gross index of bigger granularity.

In one example, multiple PCI report can be produced.Including that the multiple communities/transmission using multiple antennas is grasped In work, particularly with HS-SFN, it may occur however that situation be to need to notify the network Liang Ge community preferred precoding of UE respectively Weights, even if because may be merged and only form a downlink and may have only to one from the signal of Liang Ge community CQI.Accordingly, it may be desirable to report two PCI and CQI via uplink feedback channel.

Embodiments below may be used for reporting multiple PCI:

● type B CQI by (20,10) encoding scheme, or can derive from (20, the 9) encoding scheme of (20,10) Coding.Additional bit may be used for reporting the PCI of the second community.

● two PCI can transmit in two subframes in a tdm fashion.Such as, in even number subframe, the first community PCI is carried in CQI/PCI message, in odd number subframe, reports the PCI of the second community.

In one example, CQI can be identified by the CQI template specified.When via uplink feedback physics When channel transmits, different types of CQI can identify by defining one or more report template, and this template is with specifically CQI/PCI is presetted by mode across subframe.These templates can be known for UE and node B.Therefore, once use Particular report template is also configured with the timing of masterplate and starts, and node B just can be capable of identify that what oneself received according to subframe numbers The right type of CQI.

One way of example of definition CQI template can be introduced into the formula using subframe numbers as identifier.Cause The continuous frame number associated for CFN(and DPCH) may have been carried out in already present HSPA cellular system wireless for identifying Frame, can associate as follows by it easily with subframe:

Wherein m reflects the timing on border relative to up-link DPCH in radio frames of each subframe of HS-DPCCH Relation.According to HS-DSCH relative to DPCH border transmission timing, m can take in one group of five possible values.

In one embodiment, can be according to reporting that the subframe numbers of CQI defines CQI mould based on formula Plate.Such as, if being calculated as during the custom-designed formula of certain types of CQI meeting a set condition, it is possible to report this class The CQI of type.

A citing be given below:

1. assume that J type of cqi/PCI will be reported, N_cqi_ Class1 (N_cqi_Type1), N_cqi_ type 2(N_ Cqi_Type2) ..., N_cqi_ type J be the sequence number of each type CQI being expected between M_cqi subframe transmit.

If 2. m meets

UE will transmit CQI or the PCI/CQI value of synthesis.

If 3. m meets

UE by Report Type 1CQI, if or

Keeping, UE is by Report Type jCQI.

Wherein in formula:

● k ' is the CQI feedback cycle represented with subframe

● the value of m is calculated

●WithRepresent closest to the integer of x, respectively from less or greater than.

When noticing if UE is configured to MIMO operation, above-mentioned embodiment can also be applied to type A or Type B is as the situation of in J type defined above.

The parameter group of the definition CQI template used above, N_cqi_ Class1 ..., N_cqi_ type J and Mcqi, Can be come predefined by network via high level or be pre-configured with.Need to adapt to the difference of different application scene Asking, network can also configure the such parameter of many groups, and its use can be indicated via L1 or higher order by network, or Person is triggered by some condition.

The CQI masterplate simultaneously using mixing can be utilized.As a result, CQI there may come a time when to rush in certain subframe Prominent.In such a case, it is possible to one CQI template of regulation has higher priority, so if it occur that conflict, it just may be used To have precedence over the rule of other CQI that other masterplates produce.In another example, different types of CQI can be divided not Same priority, the CQI type so with higher priority can have precedence over the CQI type of relatively low priority.

There is the CQI masterplate in different CQI feedback cycle (being defined by k ' in formula) can also configure simultaneously and make With.Such as, frequently the CQI/PCI of report can be allocated a short CQI feedback cycle, and the CQI/ of less timely change PCI can be associated with a longer CQI feedback cycle.When two report templates clash in subframe, can be so Lay down a regulation, it is simply that long CQI/PCI can be selected to transmit because it may infrequently occur, or can select short The CQI/PCI of time transmits because it may be more important.

Noticing that CQI and PCI can decouple in their type definition, this means that CQI and PCI can not be always It is merged into identical type to form synthesis CQI/PCI.This allows different types of motility permissible in CQI and PCI centering Even if providing CQI and PCI to merge to transmit and can also use the probability of single report template or feedback cycle respectively.

In one example, it is stipulated that CQI/PCI report template can by use show different types of CQI/PCI across The definition table of the sequence arrangement of multiple subframes completes.This table can be pre-defined or pre-by network by standard agreement First configure.For example, it is assumed that the CQI/PCI of Class1 and type 2 can be the CQI/PCI needing frequently report, and type 3 CQI/PCI can be with life-time service, and report template can be defined as foloows:

The definition citing of table 6CQI report template

Subframe 1	Subframe 2	Subframe 3	Subframe 4	Subframe 5
					Class1	Type 2	Class1	Type 2	Type 3

In another embodiment, following manner can be used the report of regulation CQP is carried out when UE is configured in MP pattern Template:

1) UE can obtain the PCI/CQI value of serving HS-DSCH cell.

If MP_Active is not 0 and Secondary_Cell_Active not to be 0, UE can also obtain activating the The CQI/PCI value of two serving HS-DSCH cell, as defined in the subclause 6A.2.1 of 3GPP TS25.214.

CQI constructs from CQI/PCI value.

2) for k=0, UE can not transmit CQI/PCI report.

For k > 0, when DTX_DRX_STATUS is not TRUE, UE can transmit in each subframe and include servicing HS- The CQI/PCI report of the CQI value of DSCH community, each subframe starts from m × 256 after the up-link DPCCH frame being associated Individual chip, wherein m meets:

Mod k '=0 wherein k '=k/ (2ms)

Wherein CFN represents the Connection Frame Number of DPCH of association, five of m may the group of values can be according to R1-104157 In subclause 7.7 described in calculate, it is entitled " apply in Single Frequency Network DC-HSDPA UE ", Qualcomm compile Write.

3) UE can repeatedly transmit from 1) in the respective time slot distributing to CQI/PCI that obtains through next (N_ Cqi_transmit-1) follow-up HS-DPCCH subframe include serving HS-DSCH cell CQI/PCI value CQI/PCI report, as Defined in R1-104157.UE can not support the situation of k ' < N_cqi_transmit.

4) if from 1) obtain other CQI/PCI report, UE can according in table defined sequentially transfer this CQI/ PCI reports, and in next N_cqi_transmit period according to 2) and 3) in CQI/PCI report that transmission repeats each type CQI/PCI.UE can not support the situation of k ' < 2 N_cqi_transmit.

5) UE can be except 2), 3) and 4) described in addition to other subframes in do not transmit CQI/PCI report.

In another embodiment, if using TDM mode to transfer two classes CQI by different subframes, class CQI exists Even subframe is reported, another kind of CQI reports at odd numbered sub-frames.Such as, first kind CQI can in even-numbered subframe transmission, Two classes CQI can be in odd-numbered subframe transmission.

In another example, it is possible to use different channelization codes or CQI field identify CQI.Such as, if Employing double-channel code as above or double CQI field HS-DPCCH frame structure, class CQI can be associated with one Specific channelization codes or a CQI field.Therefore, CQI type can be transmitted to by where is it identify.

In another embodiment, CQI can be that network controls.Such as, network can be such as with dynamically side Formula is controlled what kind of CQI via L1 or in semi-static mode can be transmitted by high level, transmission control signal.Example As, the newer command in the HS-SCCH sending UE to can be introduced, with in detail instruction network it may be desirable to what kind of CQI.This Individual embodiment can make network control the CQI behavior of UE comprehensively.

In illustrating at one, network can also configure UE and have the CQI/PCI report mould in multiple different CQI feedback cycle Version.These report templates dynamically can switch via the instruction of L1 or high-level signaling as mentioned above according to network.Network Control signaling and can also support that periodic CQI/PCI reports, wherein UE upon receipt of carry out the demand of automatic network just can be by Demand transmits certain types of CQI/PCI or CQI/PCI sequence.

In one example, CQI can be triggered.Require as previously described to support that the CQI/PCI of multicast communication may Report is need not to network at certain special time.This can reduce signaling consumption.Transmitting these CQI/PCI can be at UE by certain A little conditions trigger.The triggering rule of report MP CQI can include following one or combination:

● the CQI measurement from signal to Serving cell is likely lower than threshold value, and this threshold value can be via height by network Layer signaling is predefined or is pre-configured with

ο alternatively, the signal rank (such as, RSCP) of the reception of Serving cell or with reference to DL channel (such as, CPICH) Quality (such as, Ec/Io) can compare with door restrictor, this threshold value can be optionally by predetermined or high The value of layer signal instruction adds a side-play amount and obtains.

● the CQI measurement of the non-service cell from signal to activity group could possibly be higher than threshold value

ο in one embodiment, the signal rank (such as, RSCP) of the reception of non-service cell or with reference to DL channel The quality (such as, Ec/Io) of (such as, CPICH) can compare with door restrictor, this threshold value can by predetermined or The value of person's highest level signal instruction adds a side-play amount and obtains.

● the CQI difference perceived between Serving cell and non-service cell can be less than threshold value.

ο in one embodiment, signal rank (such as, RSCP) that Serving cell and non-service cell receive or ginseng The difference examined between the quality (such as, Ec/Io) of DL channel (such as, CPICH) can compare with door restrictor, and this threshold value is optional Ground can obtain by adding a side-play amount to predetermined or highest level signal instruction value.

● measure trigger event according to RRC.Such as, after UE reporting event 1a and before event 1b, from sending work to Dynamic group measures, in the signal of non-service cell, the optimal CQI obtained and could possibly be higher than threshold value

● UE can be configured to run on soft handover or soft handoff mode.

● the report of CQI information can be network-triggered

Alternatively, UE can be specific according to be successfully decoded on the HS-SCCH that arbitrary cells is transmitted from activity group for ο Identifier triggers CQI transmission.

Notice below, be triggered and can include CQI's or PCI or CQI and PCI for the CQI field reported Information.

In one example, HS-DPCCH can be designed to HARQ-ACK feedback.Such as, multiple HARQ-ACK are permissible Transmit for single-frequency multithread (MF).May need to propose between website and the design object of community in website.Therefore, at these they quilts Treat respectively.

When designing HS-DPCCH between website, owing to the asynchronous behavior Liang Ge community of UMTS system is likely to be out of synchronization.For Inter-site cell, it is impossible to assume synchronised clock.As a result, may there is different time offset, due to system at two frame boundaries Clock comes from different clock sources, and subframe may mutually be drifted about during certain special time cycle.At this asynchronous environment In the design of single uplink feedback may be highly difficult, because the timing demands of downlink transmission may be difficult to meet. UE application may there be is the strictest restriction to meet this design of timing requirements on two different frame borders.

System and method embodiment can use a kind of technology to have the ACK/NACK of Liang Ge community coding independently Feedback, and there is two HS-DPCCH fields of separate configurations, the downlink frame boundaries that each of which is relevant to oneself Synchronize.In subframe, the concept of HS-DPCCH field can realize by different way according to embodiment described below.

Such as, HS-DPCCH frame structure can include double-channel code.In one embodiment, HS-DPCCH physics Channel can keep time slot format 0 with SF=256, and wherein ACK/NACK field takies first time slot, and CQI field can take Two time slots subsequently.It addition, one other channel code SF=256 can add so that realizing new feedback channel.For The ACK/NACK feedback of two downlink chain circuit data streams can be encoded separately.Accordingly, in response to coming under the first community The ACK/NACK feedback information of line link can be assigned to first feedback channel with a channelization codes, for second The ACK/NACK feedback information of community can be assigned to second feedback channel with one other channel code.By setting Meter, is likely not to have the special requirement about two feedback channel timing relationships, and ACK/NACK timing can be bound to oneself Downlink subframe.Because CQI can be distributed in two time slots after ACK/NACK field always, it is possible to Use identical timing relationship.

Figure 17 shows the example of the asynchronous feedback configuration utilizing the frame structure with double-channel code.Such as, Figure 17 Show the double-channel code HS-DPCCH with asynchronous HARQ-ACK.It can be seen that ACK/NACK and CQI is anti-from citing Feedback can 505 and 510 in two feedback channels by independent distribution, such as HS-DPCCH channel 495 and HS-DPCCH Channel 500, therefore permission each of which keeps and the time relationship of relevant downlink subframe, such as 7.5 Time slot, it is shown in 515 and 520.

In addition to processing the ability of the no frame structure of alignment, other benefits of this embodiment can be held concurrently backward from it Capacitive is found out.When MP-HSDPA pattern is activated or during deexcitation, and other HS-DPCCH channel may be by simply Close.Perhaps without switching spreading factor or changing other parameters.

Additionally, ACK/NACK can be coded independently.May provide by the HS-DPCCH receptor to a community Whether using the information of other HS-DPCCH channels, this is probably the most typical for configuration in website.Therefore, ACK/NACK solves Code detection performance can show the advantage relative to combined coding ACK/NACK scheme, this combined coding ACK/NACK scheme by May need to be determined by substantial amounts of code word space from the transmission state information of other communities in lacking.

Figure 18 shows the example of the both field HS-DPCCH design with asynchronous HARQ-ACK.Such as, HS-DPCCH thing Reason channel, such as HS-DPCCH520, can keep time slot format 1 with SF=128, and wherein HARQ-ACK1 field takies time slot Half, other HARQ-ACK2 fields can take time slot second half.Notice that HARQ-ACK1 and HARQ-ACK2 can need not In identical time slot.Time slot to be used depends on the frame boundaries of the downlink transmission being correlated with.CQI field be likely to need by Interrupt as half slot form.Such as, CQI1 takies front half slot, and CQI takies second half time slot, and each CQI field includes two Half-slot.As shown in arrow in Figure 18, within asynchronous HS-DPCCH, such as HS-DPCCH520, two up-links are anti- Feedback, or CQI or ACK/NACK, can be bound to the downlink timing shown in 530 and 535.Notice the second community 7.5 time slots can be set to approximately with the timing relationship of downlink subframe, because determining between two downlink subframe Hour offset is frequently not the integral multiple relation of time slot.

For avoiding half slot to transmit, second half the repetition from this time slot can be applied, if be not allocated in subframe Any one feedback of half-slot.

Figure 19 shows the example that combined coding HARQ-ACK feeds back.Design about HS-DPCCH in website, for website Interior community, the clock of possible Liang Ge community is to synchronize, and yet suffers between the frame boundaries of the signal of Liang Ge community transmission Clock skew.Once system has configured this clock skew is exactly constant.

In that way it is possible to need to use HARQ-ACK code book by ACK/NACK message combined coding to the code of Liang Ge community In word, such as the code word of defined in 3GPP version 9.Such as, the code book of the operation of the dual carrier in MIMO mode can be used for joining Put situation.This can be particularly applied to MF scene in website by it, two of which down link signal, such as 535 and 550 Frame boundaries may offset by a constant time, because ACK/NACK message may the bound time.

Realize in embodiment at one, HS-DPCCH physical channel, such as 555 a HS-DPCCH channel, can To keep time slot format 0 with SF=256, wherein combined coding ACK/NACK information takies first time slot 560, and CQI field can To take two time slots below, as shown in 565.As noted earlier in the disclosure can transmit many by time division multiplex (TDM) mode Individual CQI.Such as, Figure 19 is combined coding HARQ-ACK feedback citing, and subframe receives and responds to as can be seen from Figure 19 Persistent period between the ACK/NACK of this subframe is 6.3 time slots, this value along with between two descending chain circuit frames time Between offset function and change, such as the subframe 0 in subframe 0 and 550 in 535.

This unfixed timing relationship between feeding back due to the ACK/NACK of downlink subframe and the second community, will Uncertainty when downlink subframe is paired to the ACK/NACK message of the second community is likely to become problem.According to an enforcement Mode, can be that this situation defines pairing rules at this, this pairing rules may include steps of at least one:

1. definition Tolerance Parameters R, it can take the real number value between 0 to 3.Alternatively, what R can take between 0 to 3 is any Integer value.The value of R can be pre-defined by standard criterion, or is configured via RRC signaling by network.

2., when UE receives the down link data of specific sub-frame from second service community, its time of advent, it is defined as The t terminated with reference to subframe_s, can be compared with the subframe about arrived at identical time frame received from first service community Relatively.The time of advent of the subframe received by the first community can be expressed as t_p, ACK/NACK pairing rules can be defined as: if

-(3-R) < t_s-t_p≤R

The ACK/NACK message of Liang Ge community can be matched and combined coding is in same HS-DPCCH frame.Otherwise, The ACK/NACK message of two Serving cells can be encoded in the HS-DPCCH frame of another satisfied pairing condition.Notice In order to simplify expression t in formula_sAnd t_pIt is expressed as time slot.

3. definition T_pAs pre-defining or by network via the delay parameter of RRC signal deployment, carry pairing The HS-DPCCH of ACK/NACK message can receive after subframe at T from the first community at UE_pTime slot transmission, as long as

-(3-R-Δ m2) < t_s-t_p≤ (R-Δ m1)

The offset parameter that wherein Δ m1 and Δ m2 can be introduced into arrives avoiding the corresponding subframe in second service community Uncertainty in the case of the border of the pairing condition described in 2 around.As an example, T_pCan be configured so that 7.5 time slots, Δ m1 or Δ m2 can be set as 0.5 time slot.Notice offset parameter can also be predefined or By network configuration.If t_sFall into boundary condition, i.e.

R-Δ m1 < t_s-t_p≤R

HS-DPCCH frame can be transmitted by the additional delay defined by Δ m1, i.e. can receive at UE and come from the first clothes T after the downlink subframe of business community_pM1 time slot of+Δ transmits HS-DPCCH frame.

If or another boundary condition, i.e.

-(3-R) < t_s-t_p≤ (3-R-Δ m2)

HS-DPCCH frame can be transmitted in the relatively early time, i.e. come from the link subframe of first service community in UE reception After T_pM2 time slot of-Δ

4. work as the HS-DPCCH frame of the ACK/NACK message carrying pairing at time t_HS-DPCCHJoint by first service community When point B receives, network can associate a downlink subframe transmitted, if time relationship meets scope:

T_p-Δ T_p2≤t_HS-DPCCH≤T_p+ Δ T_p1

Wherein Δ T_p1With Δ T_p2Can be or predefined or by network configuration tolerance (tolerance) join Number, it is desirable to they meet:

ΔT_p1> Δ m1 and Δ T_p2>Δm2

5., when the Node-B receiver in second service community to HS-DPCCH frame, this HS-DPCCH frame can be closed by network Join a downlink subframe, if their time relationship meets:

T_p-R≤t_HS-DPCCH-t_s<T_p+ (3-R)

Figure 20 shows the example according to disclosure application pairing rules.The pairing rules proposed can apply to retouch at this Scene between the website stated.

As shown in figure 20, pairing rules 570 can be defined as follows:

1. during the ACK/NACK message of community 1 and community 2 can match and be encoded to identical HS-DPCCH frame, such as frame 560, if the corresponding down link data received in the two community meets following time relationship

-(3-R) < t_s-t_p≤R

The most in this example Tolerance Parameters R is set to 1.5 time slots.

2. the feedback frame of the ACK/NACK message carrying pairing in HS-DPCCH555 can obtain according to calculated as below HS-DPCCH delay parameter transmits

Wherein parameter is chosen as: m1=0.5 time slot of Δ, T_p=7.5 time slots and t_s-t_p=1.33 time slots.Because t_s- t_p> > R-Δ m1=1.5-0.5=1, according to pairing rules, Δ m1 additional delay amount is joined T_pOn=7.5 time slots.

The HS-DPCCH structure of the double-channel code of above-mentioned SF=256 or the both field of SF=128 can also be applied Scene in website.Such as, the feedback of the alignment of Liang Ge community is possible, because time migration can be considered variable. Result, it may not be necessary to interrupt CQI field for both field structure.Therefore, during CQI field may remain in a time slot.

Pairing rules can also be respectively applied to be configured to shown in Figure 17 and Figure 18 of double-channel code and both field Embodiment.Such as, Figure 21 is the example of double-channel code HS-DPCCH of the HARQ-ACK with alignment.Figure 22 is tool There is the example of the both field HS-DPCCH design of the HARQ-ACK of alignment.

In said one embodiment, use term " community 1 " and " community 2 ".But, the label of community 1 and 2 can not Distinguish whether this community is the first or second community.Such as, community 1 can be first service community, and community 2 can be second Serving cell.It addition, community 2 can be first service community and community 1 is second service community.And, other names also may be used To be associated in community 1 and community 2, and need not distinguish.

Although double small district HSDPA operation environment in illustrate, but major part propose embodiment, concept, System and method can apply to include in the application of more than two community.

In one embodiment, HS-DPCCH power can strengthen to ensure the reliability of uplink feedback.Because Running on same frequency, a HS-DPCCH can use.Feedback channel HS-DPCCH may must carry CQI and HARQ-ACK information The Liang Ge community included is transmitted to multiple cell.Because the wireless link to these communities is possibly used for due to channel condition The quality of uplink transmission is different, and the problem of the reliability receiving the uplink feedback between community must put forward, wherein For example, it may be possible to the direct link not existed between two node B.Method and system embodiment can be to send different districts to Feedback information individually regulate power excursion arrange.Especially, the transmitter power of the HS-DPCCH that may carry CQI/PCI can To be the Serving cell under the more weak radio condition that possible need enhancing.

In one example, power excursion can be determined by monitoring up-link power controlled state.Such as, UE can HS-is determined with the state by automatically scanning the up-link power control loop belonging to each community in activity group DPCCH power excursion.

In one embodiment, the TPC command that UE can be received from downlink F-DPCH or DPCCH by monitoring Uplink radio link situation is judged.Defining variable TPC_cmd, this variable can include with from multicast communication Serving cell in one reception TPC command be correlated with, including:

If-it is 0 from the TPC command of cell receiver at i-th time slot, the TPC_cmd (i) of this time slot can set It is set to-1；And

If-it is 1 from the TPC command of cell receiver at i-th time slot, the TPC_cmd (i) of this time slot can set It is set to 1.

By certain amount of time slot before, being expressed as N, the meansigma methods of the variable of definition can perform:

$\mathrm{TPC}\_\mathrm{cmd}\_\mathrm{average}=\underset{n=i-N+1}{\overset{i}{\mathrm{\&Sigma;}}}\mathrm{TPC}\_\mathrm{cmd}\left(n\right)$

Wherein N can be predefined or be configured in RRC connection by network.

TPC_cmd_average and threshold value that is predefined or that be pre-configured with can also be expressed as T_uCompare Relatively.If TPC_cmd_average > T_u, UE may decide that the HS-DPCCH transmitted by the Serving cell of monitoring needs power Strengthen.Another threshold T_d, it is also possible to the delivering power introducing the HS-DPCCH processing Serving cell needs to be turned down Situation.If, TPC_cmd_average < T_d, UE may decide that Serving cell needs power to reduce.

The decision of the delivering power of regulation HS-DPCCH can be according to above-mentioned method based on TPC, or according to from network The power grants condition for ul transmissions received is carried out.If UE does not receive enough merits from network dispatcher Rate mandate, may not allow the enhancing of HS-DPCCH power, even if method based on TPC requires that power strengthens.

In one example, power excursion can move one or more by up/down in power offset table Entrance regulates.Because can receive TPC command on the basis of time slot to time slot at UE, power excursion regulation can dynamically be entered OK, may be in sub-frame basis.Such as, additional power offset values, it is expressed as Δ_{secondar_boost}Can be configured also by high level It is added to Δ_CQI、Δ_NACKOr Δ_ACKOn, as long as CQI or HARQ-ACK field is reported to monitored Serving cell by expectation.

In one embodiment, this additional power excursion, power can be identified as and strengthen, may apply to use On whole HS-DPCCH of two Serving cells, as long as multicast communication pattern can be activated or configure.In this case, Additional power offset can determine by combining the decision of the Serving cell of above-mentioned use TPC monitoring method.Such as, if appointed Yi Yige community requires power excursion, and power strengthens will be applied to whole HS-DPCCH always.

Above-mentioned embodiment can provide as follows with example standards text for the algorithm 3 processing TPC command:

When UE is in MP pattern, UE can process the TPC life received by the Serving cell in cycle from N time slot Order, wherein N can be the integer configured by high level.Can calculate in the meansigma methods of N slot cycle according to the TPC command received The variable TPC_cmd_average merged:

$\mathrm{TPC}\_\mathrm{cmd}\_\mathrm{average}=\underset{i=1}{\overset{N}{\mathrm{\&Sigma;}}}\mathrm{TPC}\_\mathrm{cmd}\left(i\right)$

The value of the TPC_cmd being wherein labeled as i at a time slot can obtain as follows:

If-from second service community receive TPC command be 0, TPC_cmd (i) can be-1；And

If-from second service community receive TPC command be 1, TPC_cmd (i) can be 1.If TPC_cmd_ Average > Tu, wherein Tu is the integer threshold value configured by high level, then the through-put power configured by high level promotes Δ_{secondar_boost}The power excursion of HS-DPCCH field that may be added to correspondence is arranged, if they and monitored service It is correlated with in community.

In another embodiment, power control algorithm can be revised, and so can apply in whole up-link Power strengthens to allow the more preferable reception of second service community.Such as, when UE wireless link from different radio link set When the TPC command individually received obtains the TPC_cmd merged, by ordering at the TPC received from the first and second communities Apply bigger weights can realize this concept in order.

The citing realizing Weighted T PC_cmd can specify that following for processing TPC command: merges for each TPC command In the cycle, UE can be at each power control command TPC_iOn carry out soft symbol decisions W_i, wherein i=1,2 ... N, wherein N is more than 1, And being the quantity of TPC command from the wireless link in different radio link group, this can be the first stage merged Result.

UE can obtain the TPC command merged, and TPC_cmd, as all N number of soft symbol decisions W_iFunction gamma:

TPC_cmd=γ (α W₁,αW₂,...W_N), wherein TPC_cmd can be with value 1 or-1.

Wherein α > 1, and be the scaling factor of the soft symbol decisions being applied to the first and second Serving cells, high level come Configuration.

Function gamma can realize following rule:

If N number of TPC_iOrder is random and incoherent, has the identical probability transmitted as " 0 " or " 1 ", The output of the γ probability equal to 1 is more than or equal to 1/ (2^N), the output of the γ probability equal to-1 is more than or equal to 0.5.And, if come The TPC command arranged from all wireless links is the most reliably " 1 ", then the output of γ can equal to 1, this TPC command according to 3GPPTS25.214(entitled " physical layer procedure (FDD) ") 5.1.2.2.1 or 5.1.2.3 part be all not to be left in the basket , and the most uncared-for TPC command arranged if from all wireless links is the most reliably " 0 ", then the output of γ Can be equal to-1.

In an example realizing Weighted T PC_cmd, TPC Processing Algorithm, the value of TPC_cmd is for front 4 TPC command The merging cycle can be zero.After 5 TPC command merge the past in cycle, UE can determine the 5th TPC command as follows The value of the TPC_cmd in merging cycle:

UE can for five TPC command be each group in the N group of a group as follows and determine an interim TPC life Order, TPC_temp_i:

For being included in the first and second Serving cells in MP transmission:

If in-one group, all 5 hardware judgements are all " 1 ", then TPC_temp_i=α.

If in-one group, all 5 hardware judgements are all " 0 ", then TPC_temp_i=-α.

-otherwise TPC_temp_i=0.

Its configuration α >=1 on the middle and senior level.

For other communities in activity group:

If in-one group, all 5 hardware judgements are all " 1 ", then TPC_temp_i=1.

If in-one group, all 5 hardware judgements are all " 0 ", then TPC_temp_i=-1.

-otherwise TPC_temp_i=0.

It addition, UE can obtain the TPC command that the 5th TPC command merges the merging in cycle, TPC_cmd, as all N Individual temporary power control command TPC_temp_iFunction gamma: TPC_cmd (the 5th TPC command merge cycle)=γ (TPC_ temp₁, TPC_temp₂..., TPC_temp_N), wherein TPC_cmd (the 5th TPC command merge cycle) can with value 1,0 or Person-1, γ is given by being defined below:

If TPC_temp₁To TPC_temp_NIn any one equal to-, TPC_cmd is just set to-1

Else if TPC_temp_i> 0.5, TPC_cmd is just set to 1.

Otherwise TPC_cmd is set to 0.

In one example, power excursion can be set by monitoring downlink channel status.Such as, calculate at UE The CQI value of downlink of Liang Ge community can compare.If worse than the first community of the CQI of the second community, right The power excursion that the feedback information possible application carrying CQI and HARQ field of the second community is higher.If contrary CQI is preferable, Relatively low skew can be applied.

In another embodiment, UE can be by monitoring the Downlink Radio Link state of different districts, such as Path loss or DL CPICH channel quality determine HS-PDCCH power excursion.Such as, if the channel quality ratio of the second community First community good, the HS-PDCCH feedback channel of that community can be applied relatively low transmission power by UE.Otherwise, UE may make By higher through-put power.Additional offset can apply on the power excursion of regulation to compensate downlink and up-link The difference propagated.

In one example, power excursion rule can be based on HS-PDCCH frame structure.What is used according to being probably The HS-PDCCH frame structure of sample, can (be defined as activation/deactivation SF-DC by 1/0 to operate based on SF-DC pattern respectively Instruction) and MIMO configuration is predefined or regulation HS-PDCCH power excursion rule is as follows:

● if HS-PDCCH physical channel can keep time slot format 0 with SF=256, and wherein CQI field can take two Individual time slot, multiple CQI can transmit by TDM mode, they is carried in different subframes, and the power of CQI field is inclined The table 7 that shifting can be shown below is given.

● if HS-PDCCH physical channel can keep time slot format 1 with SF=128, and wherein CQI field can take one Individual time slot, double CQI fields are dispensed in subframe, and the power excursion of CQI field can be given in Table 8, wherein in table 7 The power excursion of scheme 1 increases the loss of 1 processing gain brought with compensation due to SF128.It may be desirable to the power to scheme 1 Skew increases the loss of 2 processing gains brought with compensation due to SF128.

● if HS-PDCCH physical channel can keep time slot format 0 with SF=256, and wherein CQI field can take two Individual time slot, another SF=256 channelization code may be used for facilitating implementation new feedback channel (that is, double-channel HS-PDCCH Frame structure), the power excursion of CQI field can be given in Table 7.

Table 7CQI power excursion scheme 1

Table 8CQI power excursion scheme 2

Being similar to, according to using which type of HS-PDCCH frame structure, above-mentioned concept can apply to HARQ ACK The power excursion of field:

● when HS-PDCCH frame structure has double-channel code or with SF=256 combined coding HARQ ACK, Ke Yifu Power excursion with already present R9.

● when HS-PDCCH frame structure has SF=128, there is both field, wherein to the already present rule used in R9 Power excursion increases 1(or 2) it may happen that the loss of the processing gain brought due to SF128 with compensation.

When power excursion (Δ_ACK,i, Δ_NACK,i, Δ_CQI,i) possibly for 2 communities identical time, i.e. i=1 and 2, above-mentioned rule Then can apply to corresponding to 2 HS-PDCCH channels of 2 communities in SF-DC pattern.But, because 2 communities and UE it Between radio link conditions may be different, it is thus possible to be expected to determine 2 HS-PDCCH channels corresponding to 2 different districts Power excursion time consider this factor.A lot of method disclosed herein can be by different capacity offset applications in two feedback letter Road.Such as, the method can apply to confirm that the reception of HS-PDCCH is all reliable for Liang Ge community, considers other simultaneously Factor, such as, rise relevant systematic function and UE Power Limitation to level of noise.Different power excursions can be provided for From the different radio link of different districts, with the HS-PDCCH channel corresponding to channel condition worse compared with other communities Apply higher delivering power.

In one example, HS-PDCCH power excursion can be that network controls.Such as, network can be by following skill In art one or its combination control HS-PDCCH power excursion.

In the embodiment of a kind of network control method, via RRC information independence can be when Initial R RC connects Two groups of HS-PDCCH power excursions of two cell configuration, (Δ_ACK1, Δ_NACK1, Δ_CQI1) and (Δ_ACK2, Δ_NACK2, Δ_CQI2).Once This two class value can be respectively applied to each of feedback channel by transmission HS-PDCCH, UE.

In the embodiment of another network method, network configures one group of HS-PDCCH power when Initial R RC connects Deviant (Δ_ACK, Δ_NACK, Δ_CQI).When UE can apply this to organize deviant.It addition, UE can different anti-to 2 communities Feedback channel increases difference skew, Δ_i, wherein i=1,2, it is operate in the index of the community of SF-DC pattern.This secondary power is inclined Shifting can be to come predefined according to the current information of carrier wave/MIMO configuration and/or two wireless links in a standard.

In the embodiment of another network method, dynamic HS-SCCH can come according to the information of different channels condition The two groups of power excursions sending out feedback channel respectively each or power excursion index.

In the embodiment of another network method, if the network determine that information, the 2nd HS-DSCH oneself can not be received Community can tell that power excursion is raised one-level, or an absolute value in HS-SCCH by UE.UE can use it for specific Time phase, the value then using the value identical with the first community or signal to transmit resets power excursion, or keeps being somebody's turn to do Value knows that being apprised of other operates.

When being configured with MIMO mode, for the detection providing more reliable ACK/NACK to feed back, at an embodiment In, the additional power excursion of HARQ-ACK report may be used for multicast communication between website.In dual carrier HSDPA transmits, HARQ-ACK code book table is shown in down.

Table 9 may be used for reporting the ACK/NACK state of downlink transmission.As shown in table 9, can according to each individually Table is divided into different subset by the quantity of the data stream that carrier wave is transmitted.Determine according to the scheduling that network dispatcher is carried out, pass through The quantity of the stream that carrier wave is transmitted may change on the basis of each TTI dynamically.Therefore, for confirming the code book of transmission also Can between these subsets correspondingly switching at runtime.Within less codebook subset, carry out decision-making can allow ACK/NACK The performance of detection improves, or transmits the relatively low transmitter power needed for the HARQ-ACK field in HS-DPCCH.Note, when logical When knowing the scheduling decision of ACK/NACK receptor Liang Ge community, the switching subset of code book is possible because this can allow into The correct decision-making of row is to ensure the proper use of of in that TTI code book.

Table 9 when UE is configured in MIMO mode for the HARQ-ACK code book table of DC-HSDPA

For coming from the multicast communication of the Liang Ge community being positioned at different website, can demodulate and decode in different districts HS-DPCCH, can carry out downlink transmission scheduling individually simultaneously in each community.If Liang Ge community does not mutually have It is related to their scheduling decision communicate the ACK/NACK detection carried out a community and may be unaware that in other communities Transmitting how many streams.Therefore ACK/NACK state may need by the vacation running on all of code word group in code book table If test determines.As a result, ACK/NACK detection reliability is not likely to be optimum.

As the solution of the problems referred to above, in one example, when UE transmits HS-DPCCH, can be to HARQ-ACK Field introduces additional power and strengthens.It can be that subset is specific that power strengthens；Different capacity offset parameter can apply to code Different subsets in Ben.Such as, some power offset parameters are configured according to such as following table via RRC by network:

Codebook subset	Power excursion
		Liang Ge community all has double single data	Δ11
Only first community has double-current data	Δ12
		Only second community has double-current data	Δ21
Liang Ge community all has double-current data	Δ22

These power offset parameters can be integrated into during the power excursion existed arranges, and such as, transmits HARQ- By what upwardly or downwardly regulating in power meter during ACK.

Alternatively, the enhancing of constant power can apply to whole table, and this may require that network has only to configure a merit Rate offset parameter.

In one example, the multicast communication (DF-4C) of 4 communities that HS-DPCCH can be designed in double frequency.Right Include the dual frequency operation of 4 communities in multicast communication, in one example, community can be matched in groups, each of which centering Each community is all located at identical website and is provided service by identical node B.From being geographically separated in two websites Different pairs of Liang Ge community can run on a frequency, and another two community can run on another frequency.All four The data transmission sending UE to can be dispatched in community simultaneously.Therefore, the data received from all communities can be polymerized to improve little Border, district handling capacity.

Assume that HARQ-ACK and CQI are carried in single HS-DPCCH, as the biography of regulation in 3GPP the 10th edition Conducted in four carrier operation of uniting, be positioned at different website node B can individually demodulated signal, decoding with from oneself The ACK/NACK of necessity that the downlink transmission of website is relevant and CQI feedback message.

Current HS-DPCCH frame structure defined in 4C-HSDPA can be with multiplexing in DF-4C multicast communication, such as Figure 23 institute Show.Such as, spreading factor can be set to 128, to have the capacity that sum is 60 bits in HS-DPCCH subframe.ACK/ NACK and CQI field can be arranged according to Figure 24, and wherein ACK/NACK and CQI information are all divided into two message of subframe In.Such as, the A/N1 of the 515 and CQI1 of 525 can be first message, the A/N2 of 520 and the CQI2 of 530 can be second Message.

Method and system for HS-DPCCH design about the DF-4C with configuration as above is further illustrated below Embodiment.

Figure 24 shows the example that the HARQ-ACK of DF-4C maps.The HARQ-ACK information of the community of same site is permissible Intentionally be merged into synthesis message and combined coding become a code word, this code word be placed to as shown in Figure 24 535 and 540 into In the half slot that ACK/NACK field is assigned one.The Liang Ge community being designated C0 and C1 can be provided clothes by a node B Business, and the community being designated C2 and C3 can be provided service by another node B.Decode at any one node B, HS-DPCCH Device can have only to the signal of half slot corresponding to demodulation, and provides HARQ-ACK letter to the scheduler serving related cell Breath.

In the above-described embodiment, second half time slot of HARQ-ACK signal need not process.Further, it is possible to use it is less Code book because it is known that the scheduling decision for relevant community pair decodes for the HS-DPCCH being positioned at the B of same node point 's.

Figure 25 shows the example that the HARQ-ACK of once deexcitation DF-4C maps.Although be configured to run on four little District, any one of second service community can be by L1 order dynamically deexcitation/activation.If multiplexing is already present for DC- The HS-DPCCH of HSDPA design, once deexcitation Liang Ge community, such as, from different nodes B, ACK/NACK message can be weighed Map and repeat, it is intended that improving HS-DPCCH reception reliability.Illustrating as shown in Figure 25 545 and 550, wherein C1 and C2 is gone Activate.

In one example, remapping and repeating of ACK/NACK message is not allowed.This can decode bigger by prevention The performance degradation problem being shown to you that caused of code book complete.It addition, this can know joint by stoping other websites The state of activation of some B completes, and such HS-DPCCH decoder can obtain correct group of ACK/NACK information.

Figure 26 shows another embodiment that the HARQ-ACK of once deexcitation DF-4C maps.Such as 555 Hes in Figure 26 Shown in 560, encode the single ACK/NACK message from a community according to the coded method designed for single carrier.

Figure 27 shows another embodiment that the HARQ-ACK of once deexcitation DF-4C maps.Such as, Figure 27 shows HARQ-ACK mapping relations during deexcitation all of three second service communities.Figure 27 follows above-mentioned described in reference diagram 26 Similar principles.It is noted here that difference be exactly 570, by DTX code word insert the 2nd HARQ-ACK field to avoid half slot to pass Defeated.

For DF-4C, the CQI message from each community can be separately encoded and be mapped to two carried by two subframes In individual CQI.These mapping relations are shown in the 575 and 580 of Figure 28.

In above-mentioned CQI Mapping Design, it is possible to use general timing reference known to UE and node B decodes at HS-DPCCH Device identification CQI (being report 1 or report 2).If different websites node B due to use different clock sources and not Synchronize, and if Timing offset information be not transmitted to be positioned at each HS-DPCCH decoder of each node B, may be very Difficult identification CQI, causes transmitting CQI message mistakenly.

Figure 29 shows the embodiment that the CQI of DF-4C maps.In one example, from the community of same node B CQI message can be in merged and combined coding to CQI code word.When then can this code word be mapped to specific Gap.This is shown in the 585 and 590 of Figure 29.The CQI information of the community of same node B, is designated C0 and C1, can 585 always Being mapped in the time slot 2 of subframe, other communities from other nodes B can be mapped to time slot 3 590 always.Due to identical Reason, when community is deactivated, does not allow the repetition of CQI field or remap.On the contrary, remaining CQI message is permissible Encode with the coded method of single carrier.

Figure 30 shows the example that C1 and C2 CQI as shown in the 600 of Figure 30 during deexcitation maps.

As another example, if all deexcitations of all three second service community, time slot 3 is only DTXed, i.e. this Individual time slot does not has signal to transmit.
