If CQI/PMI/RI and ACK/NACK conflicts in identical subframe, if that the parameter that higher level provides SimultaneousAckNackAndCQI (while AckNack and CQI) is arranged to FALSE(vacation)If, then CQI/PMI/ RI can be dropped.Otherwise, CQI/PMI/RI can be multiplexed with ACK/NACK.Periodical CQI report can be configured in higher level ResourceOn transmitted and use PUCCH format 2/2a/2b.Reserved resource block (RB) for PUCCH 2/2a/2b Number can be by higher-layer parameterConfiguration, and the sum that can be used for the RB of PUCCH transmission in cell then can be by higher-layer parameterIt is specified.

Fig. 3 shows example PUCCH configuration.RB 310 can be according toConfiguration is the reserved RB of PUCCH.In RB In 310, RB 320 can be according toConfiguration is the reserved RB of PUCCH format 2/2a/2b.Equally, in RB 310, RB 330 can be according toThe mixing RB that can be used for PUCCH format 1/1a/1b and format 2/2a/2b of configuration.Further, in RB In 310, RB 340 can be according toThe resource that can be reserved for lasting PUCCH format 1/1a/1b of configuration.Equally, In RB 310, RB 250 can be the resource reserved for dynamic PUCCH format 1/1a/1b.In one embodiment, for PUCCH format 1/1a/1b, resource indexIt can determine the phase of orthogonal sequence index and/or the cyclic shift in each RB It should be worth.

In order to maximize the utilization rate of bandwidth, PUSCH and PUCCH can be transmitted simultaneously in identical subframe.When When WTRU 102 is scheduled for the transmission of the data on PUSCH in stator frame, this can be to avoid by being discarded as PUCCH transmission Bandwidth loss caused by reserved RB.More specifically, by making PUCCH and PUSCH concurrent transmission, WTRU in a subframe 102 can send control information in PUCCH resource and send data grouping on PUSCH, rather than by control signaling and upper Ink Shared Channel (UL-SCH) data are multiplexed on PUSCH.This can be data transmission release PUSCH resource.

Two or more component carriers (CC), which are grouped together in the polymerization of carrier wave together, can support broader transmission bandwidth, Such as it is up to 100MHz.CC can also be referred to as serving cell, and the two terms may be used interchangeably herein.At one In embodiment, CC may include one or more serving cells.In one embodiment, serving cell may include one Or multiple CC.Carrier wave polymerization can also be referred to as serving cell polymerization, and the two terms may be used interchangeably herein.

WTRU 102 can polymerize the different number of CC or serving cell for having similar and different bandwidth in UL and DL.It can be with It is scheduled as receiving the set or DL of the DL CC where the WTRU 102 of physical down link sharing channel (PDSCH) on DL The set of serving cell can be configured by dedicated signaling.

Fig. 4 shows 3 kinds of example arrangements of carrier wave polymerization.In configuration 410, symmetrical carrier wave polymerization is shown, wherein due to The component carrier number of UL and DL is identical.The extra UL component carrier of DL component carrier used in configuration 420.In the example shown In, there are 2 component carriers for DL and 1 for UL.In configuration 430, opposite situation is shown, there are 2 components to carry Wave is used for DL for UL and 1.Other combinations of any component carrier for UL and DL and number are intended public herein Within the scope of opening.

It is polymerize by carrier wave, may include that the channel state information (CSI) of CQI/PMI/RI can be by WTRU 102 for more A CC or multiple serving cells are fed back.In one embodiment, it can support for up to the maximum number of as WTRU The periodical CSI report of the downlink CC/ serving cell of configuration.Periodical CSI report can be semi-statically mapped to WTRU specifies UL CC.For example, the mapping of CSI report can use signal via dedicated signaling or higher level signaling (such as RRC signaling) Notice.

The CQI report for multiple CC or multiple serving cells on single UL CC can be implemented in a number of ways, than The portion BW of broadband CQI or multiple CC or multiple serving cells is such as recycled, reported by portions of bandwidth and CC or serving cell Point set in optimal sub-band, and/or in identical report instance report for WTRU DL CC set or DL service it is small The CQI of CC or serving cell in area's set.

In order to support the replacement embodiment of PUCCH CQI load to can include but is not limited to make in each report instance It for periodic report, and/or is used new with increased payload size with multiple 2 resources of PUCCH format, using PUSCH CQI structure.

The CSI structure of modification can be used to complete in extension CSI load.Increased CQI payload size can pass through modification PUCCH is realized using PUSCH resource.Independent RB can be allocated for new CQI structure, and can keep simultaneous backward Hold.

In one embodiment, DL CSI can be reported for the subset of DL CC or serving cell, opened with reducing report Pin.For example, DL CSI report CC set or DL CSI report service cell set can be defined.CC set, which can also be referred to as, to be taken Business set of cells, and the two terms may be used interchangeably herein.WTRU DL CQI/PMI/RI reports that CC set can be by Definition is to reduce the quantity that WTRU 102 is the feedback that multiple CC are reported in a report instance.CC set or serving cell collection Conjunction may include the DL CC set or service cell set by dedicated signaling configuration, and for the dedicated signaling, WTRU 102 can be with It is scheduled to transmit periodicity and/or aperiodicity CSI report on UL.CSI report CC set may include WTRU DL component The subset of carrier set.WTRU 102 can transmit CSI report for the subset of DL CC or the DL serving cell configured by dedicated signaling It accuses.For example, WTRU 102 can be DL CSI report CC collection for CC/ serving cell transmission feedback, these CC/ serving cells A part of conjunction or DL CSI report service cell set (RCCS).

DL CSI RCCS can be configured by higher level signaling.For example, higher level can be via configuration parameter (such as CQI- ReportComponentCarrierSet) DL CSI RCCS is configured.The parameter may be embodied in IE CQI- It is as follows in ReportConfig:

It in one embodiment, can be CSI report pattern definition two different independent DL RCCS (for example, one A to be used for periodic report mode, one is used for acyclic reporting mode).For example, RCCS may include being matched by dedicated signaling DL component carrier/serving cell the set set, wherein WTRU 102 can be scheduled on UL for the dedicated signaling Transmit periodical CSI report.Periodic report CC set/service cell set may include the son of WTRU DL CC set Collection.RCCS may include the DL component carrier/serving cell set configured by dedicated signaling, wherein for the dedicated letter It enables, WTRU 102 can be scheduled to transmit aperiodicity CSI report on UL.Acyclic reporting CC gathers/services small Area's set may include WTRU DL CC set/service cell set subset.

For example, when e node B does not need to carry out in detail for one or more CC in the CC set of WTRU being configured Feedback of channel information report when, WTRU 102 can be configured as is excluded in its acyclic reporting those CC feedback, with Maximizing bandwidth utilization.For example, when e node B is subjected to big feedback overhead due to user a large amount of in system, e node B It can determine to limit by configuring periodic report for the CC subset in each of DL CC set of WTRU being configured Expense processed.This can be lifted at the report configuration flexibility at e node B.

It can periodically be configured by higher level signaling with aperiodicity CSI RCCS, for example, via such as cqi- The two of ReportComponentCarrierSetPeriodic and cqi-ReportComponentCarrierSetAperiodic A configuration parameter.For example, these parameters may be embodied in IE CQI-ReportConfig, it is as follows:

CSI RCCS can be configured by using the bit diagram of such as 5 bits (assuming that supporting 5 component carriers).Root According to the number of the component carrier of DL configuration, the bit of predetermined quantity can be used to configure CSI RCCS.

In one embodiment, it can periodically be transmitted parallel in identical subframe with acyclic reporting.For example, When both periodicity and acyclic reporting occur in identical subframe, can transmit in the burst periodical and aperiodic Property report both.

When both periodicity and acyclic reporting are related to identical DL CC or serving cell, WTRU 102 can be passed Send acyclic reporting.Periodic report can be dropped.When periodicity and acyclic reporting correspond to different CC/ services Cell, WTRU 102 can transmit both periodicity and acyclic reporting in the burst.WTRU 102 can be WTRU One or more CC in 102 component carrier set transmit periodic feedback, and are other CC transmission aperiodicity in set Report.

Fig. 5 shows the exemplary method using carrier wave aggregated report channel state information.It, can be with as shown, in 510 Receive the instruction for being used to transmit aperiodicity CSI report.In one embodiment, can receive for CSI information (such as CQI, PMI and/or RI) acyclic reporting request.For example, the instruction for being used to transmit aperiodicity CSI report can be one A subframe (for example be received in subframe n).In one example, WTRU 102 can receive downlink control in subframe n Information (DCI) format 0.DCI format can transmit authorization resources for the uplink on PUSCH.In DCI format, CQI request Field can be set to 1.In one example, WTRU 102 can the receiving random access response authorization in subframe n.With In machine access response authorization, in the case where based on contention-free random access procedure, CQI request field can be set to 1. Based on the instruction, WTRU 102 can determine that WTRU 102 should execute non-week in subframe (such as subframe n+k) on PUSCH CQI, PMI and/or RI of phase property are reported.In one embodiment, 4 can be equal to for FDD, k.

As shown in figure 5, serving cell or service cell set can be determined in 530, wherein can be for these clothes Cell of being engaged in reports CSI.WTRU 102 can determine serving cell or service cell set, wherein can be according in following methods At least one, for these serving cells report CQI, PMI, RI or in which any combination.For example, the determination can be based on The instruction received, such as the DCI received or other received contents.

In one embodiment, once being decoded to instruction received in subframe n, it can determine that DL service is small Area or DL service cell set.As described above, received instruction may include that uplink DCI format and/or random access are rung It should authorize.DL can be determined based on including the UL authorization in received DCI format or received random access response authorization Serving cell or DL service cell set.For example, DL serving cell or DL service cell set may include by UL authorization (such as In received uplink DCI format or received random access response authorization UL authorization) instruction PUSCH transmission clothes Business cell.For example, received uplink DCI format or received random access response authorization may include such as CSI request The field of field, CQI request field etc..The field may include instruction aperiodicity CSI report whether trigger and/or for which The value of DL serving cell or DL service cell set triggering CSI report.

For example, DL serving cell or DL service cell set can correspond to and can be using the UL serving cells of UL authorization Associated DL serving cell.UL serving cell may include Pcell and/or Scell.Its association can be by higher level (RRC) Signaling provides, and can indicate in dedicated approach or in the broadcast in the system information (SIB2 link) of DL serving cell.

In one embodiment, the UL authorization signaled by DCI can not cause really to transmit.For example, by The UL authorization that DCI is signaled can correspond to the UL serving cell being not configured.The UL authorization signaled by DCI can be with Have with instruction uplink control information (UCI) without UL-SCH data or without the identical field of the authorization of transport block transmission. For example, the field may include the value so that IMCS=29 and NPRB≤4.The UL authorization signaled by DCI can have root According to the field that particular value is arranged, the purpose with authorization by direction is the DL service cell set for the DL serving cell reported CSI It is indicated.For example, the field may include the value so that NPRB=0.When the UL authorization signaled by DCI does not cause reality When the transmission on border, CSI (together with other UL control information) can be according to scheduled rule quilt in another UL serving cell Transmission.The rule can with when UCI may include ACK/NACK feedback (for example, including on the PUSCH of Pcell (if In the presence of if)) when rule it is identical.If WTRU 102 is detected in some subframe and may not corresponded to the UL of real transmission and award Power, then the WTRU 102 can not report any aperiodicity CSI in subframe n+k on PUSCH.

In one embodiment, DL serving cell or DL service cell set can correspond to such as Pcell and/or Scell can be using the UL authorization for including in DCI format or in random access response for these DL serving cells.At one In embodiment, DL serving cell or downlink serving cells set can correspond to physical downlink control channel (PDCCH) DL serving cell, wherein can be decoded on the PDCCH to DCI format or random access response.This can be with Suitable for DCI format or do not include carrier indication field (CIF) DCI format.In one embodiment, DL serving cell or DL service cell set can correspond to the DL serving cell of physical down link sharing channel (PDSCH), wherein can be at this PDSCH is upper to be decoded random access response.In an exemplary method, can or service specific according to the carrier wave of definition it is small The specific search space in area determines DL serving cell or DL service cell set based on the decoded positions of DCI format.

The DL serving cell of configuration reports that the subset of serving cell of configuration of CSI can be by acyclic reporting Higher level configuration.For example, the subset for executing the DL serving cell of report can correspond to the configuration for not executing periodical CSI report DL serving cell subset.

In an exemplary method, sub-frame set can be defined for can transmitting the DL serving cell of CSI report or DL service cell set.The parameter one that the combination of subframe numbers, frame number or both can be configured with other by higher level can be used Get up to define sub-frame set.For example, in the case where having carrier wave/serving cell of N number of configuration, the son of j-th of DL serving cell Frame set can be defined as the sub-frame set of satisfaction (10Nf+Ns+ offset) mould N=j, and wherein Nf is that System Frame Number, Ns are Subframe numbers and offset are the parameters configured by higher level.For example, if receiving the finger for transmitting acyclic reporting The subframe shown belongs to the set of the subframe defined for DL serving cell, then WTRU 102 can transmit CSI for the DL serving cell Report.For example, if the subframe that will transmit acyclic reporting belongs to the set of the subframe defined for DL serving cell, WTRU 102 can transmit CSI report for DL serving cell.There are two DL serving cell, if in even subframe Acyclic reporting is transmitted, then the CSI report for a serving cell can be transmitted；And it if is transmitted in odd numbered sub-frames Acyclic reporting, then the CSI report for another serving cell can be transmitted.

In an exemplary method, DL can be determined based on the instruction in DCI format or in random access response authorization Serving cell or DL service cell set, wherein it is described instruction have can in subframe n received CQI request.For example, the instruction It can be carrier indication field (CIF) and/or CSI request field.Between instruction and DL serving cell or DL service cell set Mapping can be provided by higher level.For example, DL serving cell directly can be indicated via CIF field.DL serving cell can be with It is DL serving cell associated with the UL carrier wave indicated by CIF.Specific code-point can indicate that another method can be used To determine the set for the DL serving cell that will be reported.For example, once receiving specific code-point, then WTRU 102 can be based on Subframe timing determines DL service cell set.In one embodiment, once receiving first spy of CSI request field Determine code-point, then WTRU 102 can determine DL serving cell may include by UL authorization (such as uplink DCI format or with Machine access response authorization in) instruction PUSCH transmission serving cell.In one embodiment, once receiving CSI request The specific code-point of field, then WTRU 102 can determine that the set of DL serving cell may include the respective episode configured by higher level It closes.

It can also be directed to by reusing or replacing field in DCI format or field bit subset or code-point to transmit The instruction of DL serving cell or DL service cell set.It, can when existing so that when CSI requested " CQI request field " To be reinterpreted.For example, the field that can be reused or reinterpret in form alone or in combination may include " for dispatching the TPC command of PUSCH " field, " resource block is assigned and jump (hop) resource allocation " field, " modulation and coding Scheme and redundancy versions " field and/or " cyclic shift for DM RS " field.In one embodiment, other control words Section can also be reused or be reinterpreted to indicate DL serving cell or DL service cell set that CSI can be reported.

When in order to indicate to need the purpose of the DL serving cell reported or DL service cell set and when reusing field, WTRU 102 can be according to initially having different action (behave) from the associated function of the field.In an embodiment In, WTRU 102 can be according to original function without acting (action).For example, in the case where reusing TPC bit, WTRU 102 can adjust to avoid any power control of application.

In one embodiment, WTRU 102 can take action as in following situations: by what is reused The value of field instruction is predefined value or the value that is signaled by higher level.For example, " circulation for DM RS is moved Position " be reused in the case where, WTRU 102 can be arranged to as " cyclic shift for DM RS " field " 000 " or It is arranged to equally take action in the case where the value provided by higher level.The value can also depend on can be using the UL of authorization Carrier wave.

In one embodiment, for received code-point certain values, about existing function, WTRU 102 can be with It is taken action according to initial explanation.For example, in the case where " resource block is assigned and jump resource allocation " field is reused, WTRU 102 can explain the code-point it has been indicated that effectively assigning according to initial explanation.

In one embodiment, the code-point of effective or definition code-point is not corresponded to about original function, it can be by It is mapped as virtual value or behavior.For example, explaining not table according to initial in the case where " resource block appointment " field is reused Being shown with the code-point that effect is assigned can be mapped as effectively assigning.WTRU 102 can be according to mapping related with existing capability come weight The subset of the new interpretation field or bit therein.For example, being made again in " for dispatching the TPC command of PUSCH " field In the case where, first bit of the field still can be construed to power adjustment by WTRU 102.In an embodiment party In formula, WTRU 102 can be associated with one or more explanations to the field by timing relationship.

Can based on aperiodicity request whether can be received in random access response determine DL serving cell or DL service cell set.For example, in the case where the request is received in random access response, DL service cell set can be with Including main carrier or main serving cell, such as Pcell.DL service cell set may include the DL serving cell of PDSCH, wherein Random access response is decoded on the PDSCH.DL service cell set may include the cell of configuration or the cell of activation DL serving cell.DL service cell set may include can be rung by being included in random access in configuration or activation cell DL serving cell in the subset of field instruction in should authorizing.

In one embodiment, the subset with n DL serving cell can be determined.DL serving cell in the subset Number n can be defined or be configured by higher level.The subset of DL serving cell may include the CQI highest among DL serving cell DL serving cell.It can exclude to be not in activationary time or the DL serving cell in deactivation status at present from sequence.

As shown in figure 5, the CSI for identified DL serving cell or DL service cell set can be transmitted in 540 Report.In one embodiment, reporter sequence or sequence can be defined for DL serving cell or DL service cell set.It can be with The DL serving cell that will be reported is determined by recycling in the sequence or sequence of definition.For example, the DL service that will be reported Cell or DL service cell set can be defined as next DL serving cell in sequence, the sequence can be one DL serving cell, the upper DL serving cell reported in periodic report, and/or upper one reported in acyclic reporting The sequence of a DL serving cell reported in any report (periodically or non-periodically reporting).It can be excluded from sequence It is not at activationary time or the DL serving cell in deactivation status.

More than one DCI can request the CSI report for serving cell in a subframe.In an embodiment In, WTRU 102 can not report the CSI of any DL serving cell.For example, WTRU 102 can will correspond to more than one DL The request of serving cell is considered error situation.In one embodiment, WTRU 102 can be according to by predefined rule The DCI of selection reports the CSI of a DL serving cell or a DL service cell set.For example, can be decoded based on DCI DL serving cell select DCI.

In one embodiment, WTRU 102 can be according to one of aforementioned embodiments or combination is reported by each The DL serving cell of DCI instruction or the CSI of DL service cell set.In one embodiment, when existing in the description that follows When being used to determine whether one met from the context for excluding DL serving cell in CSI report in condition or combining, It include for DL in the subframe that WTRU 102 can not be in the subframe for receiving aperiodicity request or report will be completed The report of serving cell, even if it has this report according to one of preceding method.

The quantity that can be used for the information of aperiodic CQI/PMI/RI report in one subframe can be limited to one or more A factor.For example, information can be limited to the maximum number for the DL serving cell that can be reported, which is used by higher level Signal notice.Information can be limited to the maximum number of information bit or coded-bit or symbol, and (it can be modulation/coding The function of scheme), the number of the resource block of PUSCH, authorization, the presence of HARQ-ACK information or combinations thereof.

When that will be directed to, multiple DL serving cells will transmit acyclic reportings and the information will be passed in multiple subframes When sending, WTRU 102 can be determined will report by which CQI/PMI/RI of DL serving cell.WTRU 102 can be according to general below At least one to be described priority rule is determined for which serving cell will be the subframe will abandon.

When to transmit acyclic reporting according to one of above embodiment for more than one DL serving cell, and work as When cannot report all information in a subframe due to all limitations as described above, WTRU 102 can determine which takes The CQI/PMI/RI of business cell can be reported.WTRU 102 can be determined according at least one priority rule described below The CQI/PMI/RI of which serving cell will be abandoned for the subframe.

In one embodiment, multiple CSI reports can transmit in a subframe.For example, more than one DL service Cell or the CQI/PMI/RI information of component carrier can be reported in a subframe.The CSI report is cascaded first, so After be jointly encoded.The report can be coded separately, and can be cascaded by the bit/symbol of coding.When identical When including multiple reports in subframe, the mark of DL serving cell or component carrier can be included together with each report.

In one embodiment, the predefined sequence of each cascade CSI report and/or position are to 102 He of WTRU It is known for eNB 140.WTRU 102 can generate CSI report according to the predefined sequence of cascade report or position, And the reception eNB 140 can handle these CSI reports according to predefined sequence or position.In an embodiment In, DL serving cell or component carrier identify accordingly can different each reports included together.

In one embodiment, when reporting the more of more than one DL serving cell or component carrier in a single sub-frame When a CSI report, truncation (tail biting) convolutional encoding (TBCC) encoding scheme can be used, information bit is combined Coding.Also other encoding schemes, such as Reed-Muller (RM) encoding scheme can be used.It in one embodiment, can be with Use a variety of encoding schemes.TBCC is more suitable for logarithm purpose information bit and is encoded, and RM is more suitable for when the letter to peanut When breath bit is encoded.In this way, combining a variety of encoding schemes can be improved performance.

It in one embodiment, can be using the triggering method of different encoding schemes.Single thresholding can be used Or multiple thresholdings determine which kind of encoding scheme used.

In one embodiment, the total size of the multiple reports transmitted in a subframe can be compared with threshold value Compared with.For example, WTRU can be determined using specific when the size of information bit to be encoded is equal to or over the threshold value Encoding scheme, such as TBCC.When the size of information bit to be encoded is less than or equal to the threshold value, WTRU can determine Surely different encoding schemes, such as RM are used.Multiple DL serving cells for being transmitted in one subframe or component carrier it is multiple CSI report can carry on PUSCH.In one embodiment, when the multiple DL serving cells transmitted in a single sub-frame Or multiple CSI reports of component carrier can be when carrying on PUSCH, PUSCH can carry control information.Implement at one In mode, PUSCH can say that other information carries together with CSI report.

It in one embodiment, can be by the size of each and thresholding of the multiple reports transmitted in a subframe Value is compared.As described above, when multiple CSI reports of multiple DL serving cells or component carrier are reported in a single sub-frame When, information bit can be encoded respectively.Different CSI reports can be used different encoding schemes and be encoded.Needle The trigger mechanism based on one or more thresholding of encoding scheme can be used for being separately encoded report.For example, working as When the size of first report is more than the threshold value, WTRU 102 can be determined as the first report and use specific encoding scheme, example Such as TBCC.When the size of the first report is equal to or less than the thresholding, WTRU 102 can be determined as the second report and use spy Fixed encoding scheme, such as RM.

In one embodiment, WTRU 102 can determine the periodicity that CQI/PMI/RI is executed in given subframe The DL serving cell or DL service cell set of report and Report Type in the burst.For example, WTRU 102 is first Determine the type of report (if any) transmitted in stator frame for each DL serving cell, the determination by The limitation of following description.For example, can have the report of period CQI with different parameters value respectively for each DL serving cell Accuse configuration (including determining the different types of period of report and the index of offset).In one embodiment, when being such as used for When determining whether that excluding one or more condition described in the context of DL serving cell from CSI report is satisfied, WTRU 102 can not include the report of DL serving cell, even if it can have report according to one of the method for front.

In one embodiment, WTRU 102 can determination can transmit in the burst for multiple DL serving cells Report.This can occur for example when the report configuration of the periodic report of two DL serving cells is configured in them all In the case where being reported in specific sub-frame.Transmitting information content required for these are reported and can exceed that can carry in the subframe The maximum quantity of information, (for example, by PUCCH the PUSCH resource for being assigned to WTRU 102).The DL service of transmission report The number of cell may be more than that the maximum number of the definition of DL serving cell of report is transmitted in a subframe.WTRU 102 It can be transmitted as the subset for transmitting originally determined report in the subframe.WTRU 102 can be according to described below excellent At least one of first grade rule selects the subset of the report that can be transmitted in the burst.The mark of DL serving cell can be with Each report included together.When in same subframe including multiple reports, the mark of DL serving cell can be with each report Included together.

Priority can be divided to acyclic reporting or periodic report according to one or more rules.For example, It can be according to the priority between report of the priority orders that higher level provides to determine different DL serving cells.For example, should Sequence in can sequentially being configured based on RRC, or according to the explicit instruction for being directed to each DL serving cell.For example, being directed to The report of main carrier (or serving cell) (such as Pcell) can have higher priority than secondary carrier (such as Scell).

The report of different DL serving cells can be determined according to the type of the report for the transmission of each DL serving cell Priority between reporting to.For example, carrying RI feedback type 3 report can than carry respectively subband CQI, broadband CQI/PMI with And Class1, type 2 or the report of type 4 of broadband CQI have higher priority.Priority is reported and then is divided, so that Main carrier (either serving cell) Pcell has higher priority than secondary carrier or Scell.Broadband CQI/PMI report can be with There is higher priority than subband CQI report.If supporting PUCCH and PUSCH simultaneous transmission, the report on PUCCH can There is higher priority than the report on the PUSCH in same subframe.

RI information can have higher priority than CQI/PMI information.It can be excellent in the progress of DL serving cell finger tip First grade carries out this priority division before dividing.

It can be anti-according to the Report mode, PUSCH CQI feedback type and/or the PMI that are configured for each DL serving cell Present the priority between report of the type to determine different DL serving cells.For example, the load configured using Report mode 1-2 Wave can be higher than the carrier wave priority for using Report mode 2-2 to be configured.Between the report of different DL serving cells Priority can be based upon the transmission mode of each DL serving cell configuration to determine.Report has been abandoned in subframe before And from there are no the DL serving cells of transmission report can have higher priority than other DL serving cells after that.It can To be based on since the last time being that DL serving cell transmits acyclic reporting, periodic report or period or aperiodicity report The priority between report of the time to determine different DL serving cells since announcement.For example, the long period is not reported The DL serving cell of transmission can have higher priority.In one embodiment, since the non-week of CQI, PMI and/or RI Time since phase property is reported can be different.For example, CQI and/or PMI can more frequently be sent than RI.

Can according to since for main carrier or Pcell transmission periodicity or acyclic reporting since time come Determine the priority between the report of different DL serving cells.Priority can be directed to DL serving cell based on the transmission from the last time Report since CQI, PMI and/or RI knots modification.For example, the biggish serving cell of CQI knots modification can have it is higher preferential Grade.(such as I can be indexed according to that can indicate the corresponding configuration in period and offset_CQI/PMIValue) determine different DL clothes Priority between the report for cell or the service cell set of being engaged in can be with.Configuration index I_CQI/PMIIt can be provided by higher level, And it may include the index of CQI/PMI report, provided by parameter (such as cqi-pmi-ConfigIndex).It can basis Corresponding configuration index (such as index I_RI) determine the priority between different DL serving cells or the report of serving cell. Configuration for order instruction indexes I_RIIt can be provided by higher level, and may include the index for RI report, for example, by The parameter of parameter ri-ConfigIndex provides.For example, between one group of (activation) serving cell or DL serving cell, I_CQI/PMIHighest priority can be had by being worth highest (activation) serving cell or DL serving cell.This can reported For that with same period but may have and provide priority between the serving cell or DL serving cell of different offsets and divide Criterion.

The priority between the report of different DL serving cells can be determined according to the CQI value of each DL serving cell.Example Such as, the higher DL serving cell of CQI can have higher priority.For example, when that will transmit for multiple DL serving cells When periodical CSI report, the respective CQI value of DL serving cell can determine the priority of report.For example, if CQI is higher than door Limit, then can report the report of the DL serving cell.The criterion can be used for the case where WTRU selection subband.For example, broadband CQI joins It examines value and is suitable for the DL serving cell that subsequent subband differential feedback is reported.

It can have been determined not according to the knots modification of the CQI/PMI/RI since the report of last transmission DL serving cell With the priority between the report of DL serving cell.For example, the biggish DL serving cell of CQI knots modification can have it is higher preferential Grade.The priority between the report of different DL serving cells can be determined according to frequency band belonging to DL serving cell.For example, can To select DL serving cell, so that the frequency band number that DL serving cell is reported in the subframe is maximum.

It in one embodiment, can be using the multiple excellent of the report of the CQI/PMI/RI for different serving cells First grade rule.For example, can define the priority rule based on Report Type and by the rule with based on the excellent of serving cell First grade rule is applied simultaneously.In one embodiment, the priority rule based on Report Type can be smaller than in different services The priority rule that selection is carried out between area has higher priority.For example, RI can be scheduled as in a subframe being the The report of one serving cell, and CQI/PMI can be scheduled as in identical subframe reporting for second service cell.First service The RI of cell can have higher priority, even from the native region priority division rule first service cell than second clothes Business native region priority is low.Native region priority division rule, which can choose, to be configured to be reported as to have the service of maximum cycle small Area.In one embodiment, native region priority division rule can have higher than the priority rule based on Report Type Priority.For example, RI can be scheduled as in a subframe reporting for auxiliary serving cell, and CQI/PMI can be scheduled as It is main serving cell report in identical subframe.The CQI/MI of the main serving cell can be higher with priority, even from report Type priority grade rule RI type ratio CQI/PMI type priority grade is higher.In one embodiment, when there is a serving cell When being main serving cell, native region priority division rule can have higher priority than Report Type priority rule, and work as When serving cell is all auxiliary serving cell, native region priority division rule than the priority rule of Report Type priority more It is low.

In one embodiment, WTRU 102 may determine whether that this excludes DL serving cell from CSI report.Example Such as, WTRU 102 is in the subframe for receiving aperiodicity request, or in the periodical or non-week that will carry out CQI/PMI/RI Phase property report subframe in can exclude in other ways it is reported that DL serving cell CSI report.For example, when DL is serviced When cell is not on activationary time, when DL serving cell is in deactivation status, when since receiving DL serving cell When period since transmission (or newly transmission) exceeds thresholding, and/or when since its last report for DL serving cell When the knots modification (for example, absolute value) of CQI, PMI and/or RI are there are no thresholding is exceeded, WTRU 102 can be arranged from CSI report Except the DL serving cell.For acyclic reporting, WTRU 102 can exclude to be configured for periodical CQI/PMI/ The DL serving cell of RI report.When since for serving cell transmission report (periodically, aperiodicity or any report) Period be lower than thresholding (for example, forbidding timer) when, WTRU 102 can exclude DL serving cell.This is applicable to be in The DL serving cell of deactivation status.

In one embodiment, it should reduce or eliminate load ambiguity (ambiguity).For example, when sending network not When knowing the CQI information of quantity, it may occur that load ambiguity.It can be by giving CQI report filling bit so that the CQI information ratio transmitted Special number can be reduced or eliminated load ambiguity by neural network forecast.It can be by big to CQI information pre-add (pre-pending) Small indication field indicates the field how many DL serving cell will be reported to reduce or eliminate load ambiguity, and/or The number that person enables the network to CQI information by pre-add or attached cyclic redundancy check field carry out blind Detecting reducing or Eliminate load ambiguity.

In one embodiment, a kind of transmission mode can be used to be served only for broadband CQI's for carrier wave polymerization transmission Report.The feedback model for being served only for broadband CQI for the acyclic Report mode based on PUSCH may include mode 1- 0.For example, for DL CC perhaps serving cell WTRU 102 can with by assuming that the CC or serving cell whole bandwidth It is inside transmitted to calculate broadband CQI value.WTRU 102 can for by higher level configuration need acyclic reporting DL CC or Person's serving cell reports the CQI value (such as one CQI value of each CC or serving cell) being calculated.Broadband CQI value can be with Even if indicate corresponding CC perhaps first code word of serving cell channel quality when the CC or serving cell order instruction (RI) when being likely larger than 1.

The transmission mould for being served only for the feedback model of broadband CQI is supported for the acyclic Report mode based on PUSCH Formula can include but is not limited to transmission mode 1 (such as single antenna port), transmission mode 2 (such as transmitting diversity), transmission mode 3 (such as Open-Loop Spatial Multiplexing), and/or transmission mode 7 (such as WTRU specific reference signals).

In one embodiment, there can be more than one mapping table to different DL serving cells, transmission mode, or Mapping can be used the derivation of equation appropriate and obtain.

In one embodiment, at least one uplink resource allocation can be configured to WTRU 102, is served only for CSI The transmission of report.For example, upper layer (such as RRC) can pass through semi-continuous uplink grant (being hereafter denoted as SPS-CSI authorization) Configure the resource allocation.For example, in order to which PUSCH transmission can distribute private resource to WTRU 102, so that the resource period Ground can be used for CSI transmission.For example, in order to which PUSCH transmission can distribute private resource to WTRU 102, so that for WTRU 102 For the PUSCH transmission for carrying out CSI information, do not need to carry out dynamic dispatching using PDCCH.

For at least one serving cell, WTRU 102 can be configured as to be authorized with SPS-CSI.For example, being configured SPS-CSI authorization can be used for the transmission on main plot (PCell).For example, the SPS-CSI authorization configured can be used for auxiliary Transmission in cell (SCell).In one embodiment, WTRU 102 can be configured as authorizes with multiple SPS-CSI, For example, at identical serving cell (for example, on PCell), on PCell and one or more SCell, or multiple On SCell.For example, WTRU 102 can be authorized to using one or more resource blocks (RB) on the PUSCH of PCell It is repeated cyclically the uplink transmission resource of appearance.The period of CSI report can be equal to the authorization of CSI transmission being configured The multiple in the either period in period.There is effective SPS-CSI to authorize in WTRU 102 and the subframe of CSI report will be transmitted Interior, WTRU 102 can be based on SPS-CSI authorization transmission CSI report.

In one embodiment, WTRU 102 can be passed for the subframe during discontinuous reception (DRX) activationary time Send CSI report.DRX is a kind of function or operation mode, it allows WTRU 102 discontinuously to monitor PDCCH.For example, when matching When having set DRX, WTRU 102 can monitor PDCCH during DRX activationary time.WTRU 102 can transmit for certain subframes CSI report, wherein WTRU 102 can be monitored on PDCCH for the clothes indicated in SPS-CSI authorization in these subframes Other dynamic authorizations for cell of being engaged in and/or appointment.In one embodiment, WTRU 102 can not swash not correspond to DRX The subframe of live time transmits CSI.For example, when being configured with DRX and WTRU 102 is not in DRX activationary time, WTRU 102 can not transmit SRS and can not report CQI/PMI/RI on PUCCH.

WTRU 102 can receive the configuration of SPS-CSI authorization by 3 signaling of layer (such as RRC).One receives the authorization, Perhaps SPS-CSI authorization and/or the subsequent control of CSI report can be activated after predetermined delays or receiving After signaling, WTRU 102 can use the authorization being configured for CSI.For example, when WTRU 102 has periodical CSI report When effectively configuring, configured SPS-CSI authorization is can be used in WTRU 102.For example, when meeting at least one in following condition When person, configured SPS-CSI authorization is can be used in WTRU 102: once SPS-CSI authorization activation, once CSI report activates, If when being configured with DRX and being in DRX activationary time and/or when at least one SCell is activated.

WTRU 102 can according to obtained in the reception from 1 signaling of layer instruction come determine WTRU 102 can be used or Activate configured SPS-CSI authorization.For example, WTRU 102 can based on using the scrambled DCI of specific RNTI come using or Person activates configured SPS-CSI authorization.For example, if DCI reception timing can with the authorization (if activation) configured Applicable subframe occurs to be overlapped (coincide), then WTRU 102 can according to the DCI for containing explicit instruction come using or Configured SPS-CSI authorization is activated, wherein the explicit instruction is indicated be reported by using the authorization of the configuration for CSI Accuse periodicity CSI.For example, if being configured of corresponding to that the timing of the transmission of received authorization and CSI in DCI transmit is awarded Power subframe applicatory (if being activated) is overlapped, and WTRU can be used according to DCI or activation be configured SPS-CSI authorization.In one embodiment, the instruction is transmitted using the aperiodicity CSI request bit in the DCI.

WTRU 102 can be configured according to determining that WTRU 102 can be used or activate to the reception of layer 2 signaling SPS-CSI authorization.It is, for example, possible to use MAC control elements to indicate that the authorization can be activated.WTRU 102 can according to swash The reception of similar 1 control signaling of layer of control signaling or 2 control signaling of layer described in process living come stop using (for example, Deactivate) SPS-CSI that is configured authorization.

In one embodiment, when WTRU 102 determines that configured SPS-CSI authorizes the main plot being applicable in (PCell) when and/or the radio link quality of serving cell is lower than a certain thresholding, WTRU 102 can determine that WTRU 102 can With the SPS-CSI authorization for stopping using (for example, deactivation) to be configured.For example, based on being authorized to as configured SPS-CSI The downlink carrier experience physical layer problem and/or radio link of the path loss reference for the uplink carrier being applicable in The determination of failure, the SPS-CSI authorization that WTRU 102 can stop using (for example, deactivation) to be configured.For example, based on to institute The determination of uplink carrier experience physical layer problem and/or radio link failure that the SPS-CSI authorization of configuration is applicable in (such as primary or repeatedly cannot successfully complete after random access procedure), WTRU 102 can be stopped using (for example, going Activation) configured SPS-CSI authorization.In one embodiment, when the service being applicable in suitable for SPS-CSI authorization When the time alignment timer (TAT) of cell expires, WTRU 102 can determine that WTRU can stop using (for example, deactivation) The SPS-CSI authorization configured.WTRU 102 can transmit HARQ A/N to activate and/or deactivating control signaling.

If received dynamic control signaling (such as PDCCH), WTRU 102 can be to avoid the configuration transmitted about CSI Authorization CSI report.For example, dynamic control signaling can be gone back in same subframe and in the SPS-CSI authorization configured Authorized uplink transfer resource on the PUSCH of applicable serving cell.WTRU can abandon CSI report and in dynamic dispatching Data are transmitted on uplink resource.WTRU can transmit CSI report in the resource different from the SPS-CSI resource configured Perhaps a part of CSI report for example on the PUCCH or is having the transmission to conflict with SPS-CSI authorization comprising other Different PUSCH transmissions on.

In one embodiment, HARQ ACK/NACK report and CQI/PMI/RI report can be delivered separately.When In PUSCH without enough resources come simultaneously accommodate ACK/NACK and CQI when, can respectively on PUCCH transmission ACK/NACK with And CQI is transmitted on PUSCH.For example, when CQI/PMI/RI report and ACK/NACK are overlapped in a subframe, HARQ ACK/NACK can be transmitted on PUCCH.Keep for the resource adjacent with reference symbol on PUSCH of ACK/NACK signaling can To be released.In a Reporting entities, bigger channel status reporting can be transmitted on PUSCH.It can be uploaded in PUSCH Send CQI/PMI/RI.

Fig. 6 shows the example being mapped to CQI/PMI, RI and data on PUSCH.As shown, CQI/PMI, RI and Data can be multiplexed on PUSCH.As shown in fig. 6, PUSCH RS 610, CQI/PMI 620, RI 630 and data 640 can be with It is transmitted in the RB 605 on time slot 0 660 and time slot 1 670.As shown, RI 630 can on PUSCH with PUSCH RS It is transmitted in 610 adjacent resources.Because of the better quality of channel estimation, the resource adjacent with PUSCH RS 610 can be time slot Interior assured resources.Therefore, by the way that RI 630 is mapped in these resources, lower coding speed can be used for RI signaling Rate.In this way, total control signaling expense on PUSCH can lower.

Figure 16 shows the exemplary method of transmission CSI report.For example, can receive 1810 for transmitting CSI report Instruction.CSI report can be periodic report or acyclic reporting.According to the instruction, HARQ ACK/NACK report and CQI report can be overlapped in a subframe.1820, it can receive about whether permission while transmitting HARQ on PUSCH The instruction of ACK/NACK and CQI.For example, higher level can provide the ginseng of such as simultaneousAckNackAndCQIPUSCH Number.For example, can permit CQI/PMI/ when parameter simultaneousAckNackAndCQIPUSCH is set as true (TRUE) RI transmits HARD ACK/NACK and CQI simultaneously in the same subframe of PUSCH, and works as parameter When simultaneousAckNackAndCQIPUSCH is set to false as (FALSE), then do not allow WTRU 102 in the same of PUSCH HARQ ACK/NACK and CQI are transmitted in subframe simultaneously.If it is determined that in 1830 allow simultaneously transmit HARQ ACK/NACK with CQI/PMI/RI, then HARQ ACK/NACK can be multiplexed with CQI/PMI/RI, and be transmitted on PUSCH 1840.If Determination does not allow to transmit HARQ ACK/NACK and CQI/PMI/RI simultaneously in 1830, then 1850, HARQ ACK/NACK It can be transmitted on PUCCH, and CQI/PMI/RI can be transmitted on PUSCH.In another embodiment, if it is determined that Do not allow to transmit HARQ ACK/NACK and CQI/PMI/RI simultaneously in 1830, then HARQ ACK/NACK can be on PUCCH Transmission, and CQI/PMI/RI report can be dropped.

It can be configured by higher level signaling and transmit HARQ ACK/NACK on PUCCH respectively and uploaded in PUSCH Send CQI/PMI/RI.For example, can be periodical CQI report and/or aperiodicity CQI report defined parameters simultaneousAckNackAndCQIPUSCH.For example, parameter simultaneousAckNackAndCQIPUSCH can be by Including in IECQI-ReportConfig as follows:

In one embodiment, it when transmitting PUCCH and PUSCH in same subframe, can be used for multiple loads The chance of the CSI of wave is transmitted.For example, if there is the authorization for transmission PUSCH in a subframe and in identical son Report is directed to the CSI of the second carrier wave on PUCCH in frame, then WTRU 102 can be reported on PUSCH in the burst and is directed to The CSI of first carrier.First and second carrier wave can be different carrier wave.In one embodiment, at present or work as Before Na subframe after preceding subframe, not on PUCCH, report is directed to the CSI of the second carrier wave.For example, if being deposited in a subframe For the UL authorization being transmitted on PUSCH, then WTRU 102 can be directed in the burst for report on PUSCH and carry The CSI of wave.In another embodiment, if being directed to the CSI of a carrier wave not in nearest scheduled Nb subframe It reports and (for example, is only reported on PUCCH, only reports on PUSCH or reported on PUCCH or PUSCH), then WTRU 102 can be directed to the CSI of the carrier wave on PUSCH in the burst for report.

Fig. 7 shows the example chance transmission for the CSI of multiple carrier waves.As shown in fig. 7, WTRU 102 can be used it is more A carrier wave (such as three carrier waves) is operated.WTRU 102 can be configured to transmit on PUCCH periodical CSI report and It is recycled between the carrier wave.As shown, the CSI report 710 of carrier wave 1, the CSI report 720 of carrier wave 2, the CSI report of carrier wave 3 730 can be transmitted periodically, and per next carrier wave, and be recycled between them.Transmission is directed to every time on PUCCH The CSI report of single carrier wave can help network to avoid exceedingly distributing PUCCH resource for CSI report.Due to for give carrier wave Report that the frequency of CSI is lower, therefore, if it is desirable to which CSI is it is possible that delay is asked if using multiple downlink carriers Topic.The chance transmission of CSI enables the network to accelerate report to be directed to the CSI of these carrier waves by providing UL authorization to WTRU, and It does not need using complete aperiodicity CQI report as cost.

According to one embodiment, HARQ ACK/NACK information bit and CSI bit can be in the advances of scrambling and modulation Row combined coding, and transmitted in PUCCH subframe.The payload size of HARQ ACK/NACK and CSI transmission can be different.Channel Code rate becomes according to activation or configuration DL CC and/or transmission HARQ feedback or the transmission mode of periodicity CSI Change.

For example, channel encoder can be block coding type scheme, such as the knot based on DFT-S-OFDM for SF=5 Punctured (puncture) (64, k) Reed-Muller (RM) code of structure or similar structures, or for SF=3 based on DFT-S- Punctured (128, k) the Reed-Muller code of the structure of OFDM.

For example, as SF=5 (48, A) block can be obtained from the RM (32, k) of punctured RM (64, k) and/or circulating repetition Coding.It is the payload size of UCI using A when the block coding.The code word of RM can be expressed as M_i,nN number of basic sequence line Property combination, wherein N can be PUCCH load bit maximum number.According to whether signaling discontinuous biography for DL CC Defeated (DTX), for the maximum number of polymerization CC, the value of N can be for example between 10-12 bit (or similar).For example, poly- The maximum number of the CC of conjunction can be 5 DL CC.Bit sequence after the coding that the length of channel encoder output is 48 can be with It is expressed as b₀,b₁,…,b₄₇, wherein

Wherein a₀,a₁,…,a_A-1It is the input bit of channel encoder.

Addition and multiplication operation in above formula can all carry out in vector space domain, such as:

11=1,01=0,10=0,00=0,1+1=0,0+1=1,1+0=1,0+0=0.

Combined coding can be used across two time slots of PUCCH subframe.Combined coding across two time slots can be most Frequency diversity gain can be achieved in the maximum of UCI transmission on bigization PUCCH.Combined coding can be carried out in single time slot.For example, The case where for SF=5, can repeat RM (32, k) coded sequence on two time slots.For example, the case where for SF=3, it can To repeat RM (64, k) coded sequence on two time slots.

When using the RM (32, k) of rate-matched to carry out combined coding in subframe, basic sequence can be defined to support Combined channel coding.Total payload size of CSI and HARQ ACK/NACK can be more than 11 bits.The load of CQI in version 8 Size can change between 1 to 11 bits, and the payload size of the HARQ ACK/NACK of version 10 or version later can be with The bit change from 1 to 11.It in one embodiment, can be by defining additional basic sequence come in the specification of version 8 11 basic sequences provided for RM (32, k) are extended.The basic sequence of these new introducings can be other from being used to form The Reed-Muller encoder matrix of basic sequence predetermined obtains.Have been used to the applicable of traditional 8 basic sequence of version Interleave function can also be used for extension basic sequence.For example, the load in order to support at most 13 bits, it can be fixed according to table 7 Two additional basic sequences of justice and extension.

The basic sequence of the extension of table 7:RM (32, k) code

According to one embodiment, HARQ ACK/NACK information bit and CSI bit can be separately encoded.For example, HARQ ACK/NACK information bit and CSI bit can be encoded before scrambling and modulation using different code-change rates, And it is transmitted on two time slots of PUCCH subframe.HARQ ACK/NACK information bit and CSI bit can be encoded respectively, So that the performance of each control signaling can be maintained at respective target level.When the load of HARQ ACK/NACK and CSI transmission It, can be according to the desired bit error rate (BER) or Block Error Rate (BLER) operating point of given control feedback kind when of different sizes To adjust the code rate of each channel encoder.The payload size of HARQ ACK/NACK and CSI transmission can be according to activation Or the DL CC and/or transmission HARQ feedback or the number of transmission mode of periodicity CSI of configuration and it is different.

For example, when payload size is relatively small, such as 2 bits, the channel encoder may include block coding type Scheme.The block coding type scheme may include according to the spreading factor for the structure based on DFT-S-OFDM (or similar) The solid size (simplex code) of 48 or 96 coded-bits is matched to cycle rate.The channel encoder, which can be, to be cut Tail convolutional code, it can generate 48 and 96 when the output of the structure based on DFT-S-OFDM is in SF=5 and SF=3 respectively A coded-bit.

For example, the cyclic redundancy check (CRC) of n-bit can be calculated based on control information, then in channel coding It is attached to after the feedback information bits before to improve missing inspection (miss detection) performance.CRC can have variable Size, can according to the type (such as HARQ ACK/NACK or CSI) of the payload size of UCI or control signaling come pair Its size is adjusted.One non-limitative example of CRC length is 8 bits, and the false detection rate that it can be obtained is 0.4%.It should CRC can reduce the probability of the false alarm at e node B, and therefore can loosen the performance objective on Pr (DTX- > ACK). In one embodiment, the CRC can indicate the used actual payload size before the coding of WTRU 102, and/or WTRU 102 receives the mark or number of the configuration that DL is assigned or activation DL CC.Therefore, when WTRU 102 is at one Or on multiple DL CC when downlink of the missing inspection from eNB is assigned, the performance of detector can be improved.

Fig. 8 shows the unrestricted reality of a PUCCH coding strand for the PUCCH transmission based on DFT-S-OFDM Example.As shown, the UCI data 805 fed back by WTRU 102 are entered coding unit.810, UCI data 805 can be used It calculates CRC check bit (parity bit).For example, entire block can be used for calculating CRC check bit.For example, WTRU 102 CRC bit can be attached to after UCI bit.820, CRC bit sequence can be by DL CC that is being activated or being configured 830 mark or number carries out mask operation, and wherein WTRU 102 receives DL appointment on the DL CC830.It, can 840 To carry out tailed-off convolutional code.For example, the tailed-off convolutional code that WTRU 102 can be 1/3 using rate to input bit.? 850, Rate Matching block can be fed back to by the bit of coding.

In one embodiment, as shown in figure 9, sub- coding can be used before carrying out combined coding with CSI bit Device encodes HARQ ACK/NACK information bit.As shown, can be 920 come pairs by ACK/NACK sub-encoders HARQ ACK/NACK bit sequence 910 is encoded.Reed- can be passed through by the ACK/NACK bit sequence of coding Muller encoder 930 and CSI bit sequence 940 carry out combined coding to generate output bit sequence 950.

For example, when ACK/NACK payload size is smaller, such as 3,4 bits etc., ACK/NACK of WTRU 102 are compiled Code device may include simple code and/or duplication code.When ACK/NACK payload size is larger, for example, 5 to 11 bits, WTRU 102 ACK/NACK sub-encoders can be Reed-Muller code.

In one embodiment, ACK/NACK bit sequenceIt can be made first by WTRU 102 It is encoded with Reed-Muller code, such as RM (20, N_A/N)；

Wherein N_A/N∈ { 1,2 ... 11 }, N_A/NIt can make the number of ACK/NACK bit feedback, and A "=20.By compiling The ACK/NACK bit sequence a of code₀,a₁,...,a_A″Then (a ' can be expressed as with the CSI bit sequence of WTRU102₀,a′₁, a′₂,a′₃,...,a′_A′-1) be multiplexed, to generate following sequence a₀,a₁,a₂,a₃,...,a_A-1:

a_A″+i=a '_i, i=0 ..., A ' -1.

The Reed-Muller code of such as RM (48, A) can be used to sequence a₀,a₁,a₂,a₃,...,a_A-1Encoded with Generate following output bit sequence b₀,b₁,b₂,b₃,...,b_B-1:

Wherein, the PUCCH based on DFT-S-OFDM, B=48 for being 5 for spreading factor.

It in one embodiment, as shown in Figure 10, can be before Reed-Muller coding by HARQ ACK/NACK Coded-bit is added to after the CSI bit sequence of WTRU 102.As shown, can exchange quilt coding ACK/NACK and The input sequence of CSI bit sequence, to improve the DTX processing at eNB.As shown in Figure 10, ACK/NACK bit sequence 1020 It can be encoded by ACK/NACK sub-encoders 1030.It can be with CSI bit by the ACK/NACK bit sequence of coding Sequence 1010 carries out combined coding by Reed-Muller encoder 1040, exports bit sequence 1050 to generate.DTX situation It is related that the generation failure of DL Grant for resource allocation can be detected in given sub-frame to WTRU 102.In spite of there are ACK/NACK Information bit, eNB can detect the CSI information bit of WTRU 102.

In one embodiment, as shown in figure 11, the HARQ ACK/NACK by coding of WTRU 102 can be deleted In the remaining CSI bit sequence to by coding.As shown, ACK/NACK bit sequence 1110 can be compiled by ACK/NACK Code device 1120 is encoded.CSI bit sequence 1130 can be encoded by Reed-Muller encoder 1140.By compiling The CSI bit sequence of code can be fed back to Rate Matching block 1150.It can lead to by the ACK/NACK bit sequence of coding It crosses multiplexing/punctured module to be punctured in CSI bit sequence, to generate output sequence 1170.

The CSI bit sequence of WTRU 102 can be encoded and by rate-matched, to take the resource of PUCCH RB, such as 48 bits.Not punctured bit will not be influenced by the HARQ ACK/NACK bit for lacking WTRU 102, wherein 102 WTRU DL scheduling assignment, such as DTX may have been had already passed by.

For example, the channel quality bit for being input to the channel coding module of WTRU 102 (is expressed as a '₀,a′₁,a′₂,a ′₃,...,a′_A′-1), RM (32, A ') can be used to be encoded first.Export bit sequence b₀,b₁,b₂,...,,b_B-1(B= It 48) can be by as follows by circulating repetition sequenceIt obtains:

Wherein i=0,1,2 ..., B-1.

In one embodiment, ACK/NACK bit sequenceIt can be coded separately, to produce Raw b '₀,b′₁,b′₂,b′₃,...,b′_B′-1, wherein B ' is the length by the ACK/NACK sequence of coding.For example, by coding ACK/NACK sequence can be punctured in the CSI sequence by coding, it is as follows:

b_i=b '_i, i=0 ..., B ' -1.

In one embodiment, physical resource can be mapped in DFT-S-OFDM PUCCH.For example, WTRU 102 can use channel interleaver for uplink control information transmission.Increase it is thus possible to maximize obtainable frequency diversity Benefit.

For example, the channel can be carried out to by the bit sequence of coding or to the bit sequence after scrambling in bit-level Interweave, allow to by row write enter bit in one rectangular matrix, is then read by column.For example, bit sequence can be write Enter in the matrix of a 24*2 (for SF=5), or (for SF=3) in the matrix of write-in 48*2.In an embodiment In, adjacent control bit can map between two time slots.

For example, can be in symbol level application channel interleaving, the modulated symbol of adjacent uplink control information can be with It is mapped in two time slots of a subframe in the time domain first, then on subcarrier in a frequency domain in each time slot It is mapped.For example, even number QPSK symbol can transmit on even timeslots, odd number QPSK symbol is mapped on odd numbered slots.

In one embodiment, CSI and HARQ symbol can be multiplexed into PUCCH resource.For example, when to different type Information when being encoded and interweaved respectively, symbol can be from CSI (such as CQI, RI and/or PMI and ACK/NACK information) It is multiplexed into PUCCH resource.

For example, corresponding resource can be applied in single RB.For example, can in single RB about ACK/NACK and/ Or CSI load carries out dimensional measurement to corresponding resource, so that channel coding gain is improved.

In one embodiment, HARQ response can be transmitted on PUCCH.Available resources on PUCCH can be used for ACK/NACK/DTX feedback transmission.For example, HARQ ACK/NACK symbol can first map in two time slots in time domain, so It is mapped between subcarrier on frequency domain afterwards.In a kind of example, symbol can first map in a frequency domain, then reflect in time domain It penetrates.

In one embodiment, channels state report can be uploaded in PUCCH.Available resources on PUCCH are available It is transmitted in CSI feedback.For example, channel status reporting symbol can first be mapped between two time slots in time domain, then in frequency It is mapped between subcarrier in domain.In a kind of example, symbol can map in present frequency domain, then map in time domain.

In one embodiment, HARQ ACK/NACK and channel status reporting can be transmitted on PUCCH.It can answer With HARQ symbol and CSI symbol, so that different control signalings can be assigned to different size of physical resource elements.For every The size of the reserved resource of one ACK/NACK and CSI can be according to the code-change rate and/or tune of given control signaling Order processed zooms in and out.Different offsets can be used to map various control signaling information in WTRU 102.Offset can With it is semi-static by higher level signaling, statically or dynamically configure.Control signaling can be mapped, so that in ACK/NACK and CSI Each can exist in two time slots of subframe.

For example, HARQ ACK/NACK feedback and CSI can be multiplexed in identical PUCCH resource.It can determine and be used for The number of the difference of the symbol of each type of information.For example, HARQ ACK/NACK priority can be higher than CSI information.It can be with The number Q of coded identification needed for determining HARQ ACK/NACK information_{AN_PUCCH}.If Q_{AN_PUCCH}It is more available than PUCCH maximum Q_{MAX_PUCCH}Small, then CSI information can be multiplexed.It, can be according to Q in a kind of example_{AN_PUCCH}Compare Q_{MAX_PUCCH}A small threshold value Condition CSI information is multiplexed.In one embodiment, if Q_{AN_PUCCH}Equal to or more than Q_{MAX_PUCCH}, or Q_{AN_PUCCH}And Q_{MAX_PUCCH}Between less than one threshold value of difference, then only transmit HARQ ACK/NACK information.For example, can not HARQ ACK/NACK information and CSI are multiplexed.

In one embodiment, Q_{AN_PUCCH}And Q_{MAX_PUCCH}Between mapping can be fixed and can be by looking into Table is looked for provide.It in one embodiment, can be according to the number O for the HARQ information bit to be transmitted_{AN_PUCCH}Function calculate Q_{AN_PUCCH}.It in one embodiment, can be according to scale factor B_PUCCHMultiplied by the HARQ ACK/NACK information ratio to be transmitted Special number calculates Q_{AN_PUCCH}.The parameter of the function can be predefined or be provided by higher level.Scale factor B_PUCCH The ratio (fraction) of the adjustable PUCCH energy that can be used for HARQ ACK/NACK information.In one embodiment, It can be used for the symbol of HARQ ACK/NACK information and/or CSI information in can transmitting according to the PUCCH based on DFT-S-OFDM Maximum number Q_{MAX_PUCCH}Calculate Q_{AN_PUCCH}.The number of symbol can be according to using extension or conventional prefix and different.

Number of symbols Q for HARQ ACK/NACK information_{AN_PUCCH}It can correspond to Q_{MAX_PUCCH}With f (O_{AN_PUCCH} x B_PUCCH) between lesser value, wherein function f () symbol for HARQ ACK/NACK information can be provided and be less than The largest possible number thereof of parameter (argument).In one embodiment, function f () can be provided for HARQ ACK/ The symbol of nack message and the minimum that is greater than parameter may number.In view of the granularity for the number of symbols in PUCCH 1 may be greater than, function f () is defined such that the symbol that can distribute correct number.

In one embodiment, the number Q that can be used for the symbol of CSI information can be determined_{CSI_PUCCH}.For example, can lead to Cross the number of symbols Q compared for HARQ ACK/NACK information_{AN_PUCCH}With maximum number of symbols Q_{MAX_PUCCH}To calculate Q_{CSI_PUCCH}.It can be used for the number Q of the symbol of CSI information_{CSI_PUCCH}It may include Q_{AN_PUCCH}And Q_{MAX_PUCCH}Between difference.One In a embodiment, there may be the symbol that can be used for CSI information of minimum number so that HARQ ACK/NACK information and CSI can be re-used.In one embodiment, it when can be used for the number of symbols of CSI information lower than a threshold value, can lose Abandon the CSI information.

The DL serving cell that can be determined the type of CSI information according to the number of the available symbols of CSI and/or be reported Number.For example, if Q_{CSI_PUCCH}Less than one threshold value, then can only report the order instruction of single DL serving cell.

In one embodiment, the CSI information that can be reported can be determined according to the maximum code rate of CSI information Quantity.The maximum code rate depends on the type of CSI.For example, the maximum code rate of RI may be higher lower than having The maximum code rate of the other kinds of CSI of robustness requirement.For example, can be according to maximum code rate and available code ratio Special number calculates the maximum number O of the information bit that can be used for CSI_{CSI_PUCCH}.In one embodiment, O_{CSI_PUCCH}It can be with It is the product between maximum code rate and the number of available code bit, is rounded to immediate integer downward or upward or takes The immediate integer that the whole possibility number to CSI information bit matches.Between the number of coded-bit and the number of symbol Ratio K correspond to each modulation symbol bit number divided by spreading factor SF.It is above-described about by HARQ ACK/NACK Information can be used for being multiplexed different types of CSI in identical subframe with the CSI embodiment being multiplexed.For example, RI It can be multiplexed with CQI/PMI.

Figure 12 shows the reality of the control signaling mapping of a unrestricted PUCCH transmission based on DFT-S-OFDM Example.As shown, CSI resource 1240 can be placed in the beginning of RB 1210 and before starting next subcarrier in proper order It is mapped on two time slots on a subcarrier of time slot 0 1220, until all resources for distributing to CSI information are filled out Until full.On the other hand, HARQ ACK/NACK symbol 1250 can be placed in the end of RB 1210.That is, CSI 1240 can be multiplexed with HARQ ACK/NACK 1250 in the enterprising line frequency of PUCCH.

According to one embodiment, the CSI transmitted on PUCCH can use identical modulation scheme with HARQ response.It can Alternatively, different modulation schemes can be used in CSI and HARQ control signaling.It is, for example, possible to use QPSK modulation to modulate HARQ ACK/NACK, and the modulation (such as QAM16 or QAM64) of higher order can be used to modulate CSI.

Different multiplexing methods can be used.HARQ ACK/NACK symbol can be placed in the both ends of RB frequency direction.It can be with It is carried out in this way in each time slot or the symbol can be placed in one end for first time slot and be placed in for the second time slot The other end.Such arrangement can maximize the frequency diversity for HARQ/NACK symbol.Above-mentioned arrangement can be used for CSI symbol Number.In another embodiment, the subcarrier that HARQ ACK/NACK symbol is located at can be placed with each other apart Equal frequency distance.Alternatively, or additionally, the subcarrier where CSI symbol can be placed at a distance of equal or Of substantially equal frequency distance.

When CSI information and HARQ ACK/NACK information multiplexing, the coding to CSI information can be executed.It is used at one In punctured embodiment, can first by assuming that coded-bit number correspond to can be used for HARQ ACK/NACK information and The maximum number Q of the symbol of CSI_{MAX_PUCCH}To be encoded to CSI information.For example, Reed-Muller can be used in the coding Code RM (KxQ_{MAX_PUCCH},O_{CSI_PUCCH}), wherein K can be the ratio between coded-bit number and symbolic number.CSI coded-bit Then it can be interleaved, modulate, extend and be placed to available character position in PUCCH.HARQ ACK/NACK information can also To be encoded, interweave, modulation, extend, it is then placed into the subset of the character position previously used by CSI information, imitates Fruit is the punctured coding to CSI.Used character subset can be determined according to above embodiment.

It in one embodiment, can be by assuming that coded-bit number, which corresponds to, can be used for the symbolic number of CSI (Q_{CSI_PUCCH}) directly CSI information is encoded.For example, Reed-Muller code RM (KxQ can be used in coding_{MAX_PUCCH}, O_{CSI_PUCCH}), wherein K can be the ratio between coded-bit number and symbolic number.Then CSI coded-bit can be interleaved, It modulates, extend and be placed to the character position identified for CSI information.HARQ ACK/NACK information can also be encoded, Interweave, modulate, extension is then placed into the character position for being not applied to CSI information.Can determine HARQ ACK/NACK and The character position of the information of CSI.The transmission of CSI can preferentially transmit in the code word of highest quality metric, for example, signal interference Noise ratio (SINR).

WTRU 102 can be dispatched and share identical RB to carry out their UL feedback transmission.HARQ ACK/NACK and CSI Transmitting shared PUCCH resource block can control signaling expense in reduction system.

As CSI and when HARQ ACK/NACK information multiplexing, transimission power can be used as at least one following function and be adjusted It is whole: HARQ ACK/NACK bit number, the HARQ ACK/ distributed corresponding to the PDCCH transmission detected or semi-continuous scheduling Number, CSI bit number, RI bit number, and/or the biography for HARQ ACK/NACK, CSI and/or RI of NACK bit Number of symbols in defeated PUCCH is separately encoded situation.

More specifically, transimission power can be based on HARQ ACK/NACK bit number or corresponding to the PDCCH detected The HARQ ACK/NACK bit number that transmission or semi-continuous scheduling are assigned divided by the PUCCH that is used for transmission the information symbol Number or ratio.Transimission power can based on CSI bit number divided by the number of the symbol for the PUCCH for being used for transmission the information or Ratio.Transimission power can be based on RI bit number divided by the number or ratio of the symbol for the PUCCH for being used for transmission the information.With In the symbol of the PUCCH of transmission CSI or HARQ ACK/NACK number or ratio can based on CSI as described above and/or The number of HARQ ACK/NACK information bit.

CSI load can be transmitted by distributing corresponding uplink control region.In one embodiment, it reserves CSI structure can be kept for the certain resource blocks (RB) transmitted of the PUCCH in UL.When HARQ ACK/NACK and CSI are same When conflicting in subframe, CSI can be multiplexed with ACK/NACK.

Figure 13 shows the PUCCH profile instance for the resource allocation on PUCCH.As shown in it, some to keep for The RB of PUCCH transmission in UL can distribute to CSI structure.For example, from the angle PUCCH format 2/2a/2b's 1520 of system Oversized (over-dimensioned), outermost RB 1530 can be assigned to CSI structure, such as PUCCH format 3/ 3x.When HARQ ACK/NACK report and CQI report are overlapped in a subframe, PUCCH format 3/3x can be used and come simultaneously Transmit CSI and HARQ ACK/NACK.As shown in figure 13, RB 1540 can be keep for byWhat is configured is lasting The resource of PUCCH format 1/1a/1b, RB 1550 can be the resource for keeping for dynamic PUCCH format 1/1a/1b.

Figure 14 shows the instance method of transmission CSI feedback.For example, can receive 1610 and distribute to CSI report structure RB number.The CSI report structure may include PUCCH format 3/3x.WTRU 102 can by higher level according to The number that the RB of new CSI feedback transmission can be distributed in the control area PUCCH is configured.For example, WTRU 102 can be with System parameter is received from system by broadcast, such asThe system parameter can it is expected the activation UE (example supported according to system UE such as version 10 or later) average number carry out dynamic adjustment.1630, the RB distributed on PUCCH can receive The interior dispatching distribution resource for the feedback transmission using CSI structure.The resource of transmission for PUCCH format 3/3x can be with With resource index (such as) be identified.The parameter can be explicitly logical with signal by WTRU specific higher layer signaling Know.For example, those RB can be distributed to the UE of version 10 by scheduler, for using the feedback transmission of CSI structure.From version The angle of 8WTRU, the scheduler at e node B will not assign any resource on outermost RB to WTRU 102.By matching Set, this method can be to the WTRU of version 8 it is transparent, completely holding backwards compatibility.1650, CSI feedback can be outermost It is transmitted in the resource of appointment in the RB for CSI structure of the distribution of side.

It is that can maximize when frequency hopping is used by an outermost RB advantage for distributing to the control area newly introduced Obtainable frequency diversity.This method can compensate new CSI to a certain extent and carry in channel since higher expense is made At potential loss.

In one embodiment, the certain of the PUSCH transmission in the UL for CSI structure can be kept for by distributing RB loads to be transmitted CSI.Figure 15 shows the example of PUCCH configuration.As shown in it, system RB 1710 may include pre- It leaves for and passes throughThe RB 1720 of the PUCCH format 1/1a/1b of configuration, keeps for and passes throughThe lasting PUCCH of configuration The RB 1730 of format 1/1a/1b keeps for the RB 1740 of dynamic PUCCH format 1/1a/1b, keeps for the week on PUCCH The RB 1750 of phase property CSI signaling, and can be used for the RB 1760 of PUSCH.For example, with keeping on PUCCH format 1/1a/1b The adjacent PUSCH RB 1760 of RB 1740 of dynamic ACK/NACK transmission can be allocated for transmission CSI.

From the angle of system, scheduler can not dispatch any PUSCH transmission on these reserved RB.This method can be with Complete backward compatibility and transparent by scheduling appropriate to the WTRU of earlier version (such as WTRU of version 8).UE, such as The UE of the UE of version 10 or later version can pass through the maximum number about the RB for keeping for periodical CSI feedback transmission Broadcast system parameter configured.

Transmission Time Interval (TTI) binding scheme can be used for the periodical CSI feedback transmitted on those PUSCH RB. The UL covering reliability of the new CSI structure transmitted on PUSCH can be improved.This method can be regarded as that mesh can be substituted The preceding alternative in version 8 for the HARQ process of PUSCH data transmission.It therefore, can be in the same asset on PUSCH On continuous T TI set in transmission signal period report.It can be tied up by WTRU specific higher layer signaling to trigger TTI It is fixed.

WTRU, such as the UE or the UE of version later of version 10, can be by higher level according in the control area PUSCH The number of the RB of new CSI feedback transmission is distributed to be configured.For example, broadcast system parameter can be defined, such asIt can WTRU with the activation supported according to system expectation, the average number of (such as version 10 or UE later) carry out dynamic and adjust this Parameter.The resource being used for transmission can by resource index (such as) be identified.The parameter can be specific by WTRU Higher level signaling explicitly signals.

In one embodiment, CSI load can be expanded by defining the control area including one or more RB Exhibition.It may span across the individual region of one or more RB in UL to CSI for example, can distribute, it may be with or without HARQ ACK/NACK transmission.

CSI load can be extended by distributing corresponding control area.In one embodiment, it keeps in UL PUCCH transmission some resource blocks (RB) CSI structure can be kept for.
