Description

Method for channel allocation and device, channel obtaining method and device

Technical field

The present invention relates to communication technical field, be specifically related to method for channel allocation and device, channel obtaining method and device.

Background technology

Along with express network technology and development of multimedia technology, undergoing an unusual development of wireless network is swift and violent, and the development trend of wireless network evolves to packet switching from circuit switching gradually, and various WiMAX access technologies emerge in an endless stream.The swift and violent wireless network of development recent years has 3-G (Generation Three mobile communication system) (3G), local multipoint distributed serice (LMDS), WiMax system (WiMAX), third generation partner program Long Term Evolution standard (3GPP LTE) etc.

Wherein physical layer has defined some physical channels and signal in 3GPP LTE, comprise physical down shared data channel (PDSCH), Physical Multicast Channel (PMCH), Physical Downlink Control Channel (PDCCH), Physical Broadcast Channel (PBCH), Physical Control Format Indicator Channel (PCFICH), physical mixing retransmission indicating chanel (PHICH), Physical Random Access Channel (PRACH), Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH) etc.

Physical Control Format Indicator Channel (PCFICH) transmission control format indication (CFI), effect is that what OFDM symbols indication Physical Downlink Control Channel (PDCCH) takies in each subframe, the control format indication is represented with 2 bits, transmits in Physical Control Format Indicator Channel.Have one of four states (1,2,3,4) altogether, represent to take top 1 of subframe at non-MBSFN respectively, perhaps 2 symbols, perhaps 3 OFDM symbols, when MBSFN, represent to take top 1 of subframe respectively, perhaps 2 OFDM symbols, the quantity of the CCE of the big more correspondence of CFI value is many more.

What Physical Downlink Control Channel (PDCCH) transmitted is user's control information.PDCCH is made up of a plurality of control channels unit (CCE), and CCE is the elementary cell of a control channel transmission, and a PDCCH channel can take 1, or 2, or 4, or 8 CCE.It is to be user's allocation of downlink resource that PDCCH has a function, transmitting downlink data, and first CCE that PDCCH itself takies (representing with the PDCCH sequence number) is promptly corresponding with up replying/no response (ACK/NACK) channel number.As long as the user has downlink data, just have descending PDCCH indication like this, will be by the implicit ACK/NACK channel of distribution of CCE that takies.

Up responder link is to be used for carrying out the replying of downlink transmission data (receive or confiscate, represent with 1 bit), and the control channel (PUCCH) of going is physically gone up transmission.Need distribute different ACK/NACK channels for different users, it on the ACK/NACK channel time subframe (1ms), in order to improve the covering of uplink ACK/NACK channel, introduced the ACK/NACK repetition, promptly an ACK/NACK transmits on a plurality of subframes.

CFI has indicated PDCCH to take what symbols, and PDCCH is made up of a plurality of CCE, therefore can calculate the number of the CCE of PDCCH by system information and CFI.The corresponding ACK/NACK channel of each CCE, the ACK/NACK channel (the ACK/NACK channel that passes just) of the user uplink by the implicit distribution of user's PDCCH sequence number.

In the system that has the ACK/NACK channel to repeat, the distribution method of the ACK/NACK channel of existing a kind of ACK/NACK channel and re-transmission is such: suppose descending one total N CCE, the then corresponding ACK/NACK channel that just passes of keeping for is N; Suppose to carry out the user that the ACK/NACK channel repeats, descending PDCCH generally takies 4 or 8 CCE.If the PDCCH that the ACK/NACK channel needs secondary to retransmit takies 4 CCE, therefore there be N/4 user to need secondary to retransmit at most, for these users reserve the ACK/NACK channel that N/4 secondary retransmits; If the ACK/NACK channel needs the PDCCH of three re-transmissions to take 8 CCE, therefore there be N/8 user to need three re-transmissions at most, reserve the ACK/NACK channel of N/8 three re-transmissions for these users; Therefore reserve N+N/4+N/8=13*N/8 ACK/NACK channel altogether in the PUCCH of each subframe, be respectively applied for ACK/NACK and just pass, the ACK/NACK secondary retransmits, and ACK/NACK retransmits for three times.Suppose that a Resource Block comprises a ACK/NACK channel, then needs 13*N/8a Resource Block altogether.Suppose that 13*N/8a is 3, promptly need to take 3 Resource Block, then in the N that will just pass ACK/NACK channel mean allocation to 3 Resource Block, the ACK/NACK channel that same secondary retransmits and three times retransmit is also in mean allocation to 3 Resource Block, and in a Resource Block according to the sequence arrangement of the ACK/NACK channel of the ACK/NACK channel of first biography, the ACK/NACK channel that secondary retransmits, three re-transmissions.

In realizing process of the present invention, the inventor finds that there is following defective at least in above-mentioned distribution method: because the resource of uplink ACK/NACK channel belongs to semi-static configuration, broadcasting (D-BCH) in dynamic broadcast, the D-BCH cycle is far longer than a sub-frame time (1ms); And control format indication (CFI) can change in each subframe.Therefore the resource of the ACK/NACK channel of reserving can only be by the control format indication (CFI) of a certain section time maximum, be that maximum descending CCE disposes, and actual CFI may not be maximum CFI, the required Resource Block that takies when therefore not needing to take maximum CFI, but after carrying out the ACK/NACK channel allocation according to above-mentioned distribution method, all can have in each Resource Block just and pass, the ACK/NACK channel that secondary retransmits and three times retransmit, even the required Resource Block that takies when therefore not needing to use maximum CFI, also Resource Block can't be discharged, cause the waste of resource.

Embodiment

For make purpose of the present invention, technical scheme, and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.

Introduce the method for channel allocation that the embodiment of the invention provides earlier, Fig. 1 has described the flow process of method for channel allocation embodiment one, comprising:

Step 101, determine the quantity of the ACK/NACK channel of needs reservation according to CFI value maximum in a period of time;

When the CFI value is determined, just the quantity of the CCE corresponding can be determined, and then the quantity of corresponding ACK/NACK channel can be determined according to system information with the CFI value; Wherein, because CFI can change in each subframe, therefore the number needs of the ACK/NACK channel of reserving will be determined according to the CFI value of maximum, thus the needs when guaranteeing the ACK/NACK channel of reserving can to satisfy CFI value being the CFI value of maximum;

At least one Resource Block that step 102, the ACK/NACK channel needs of determining to reserve according to the quantity of ACK/NACK channel take;

Because the quantity of the ACK/NACK channel that each Resource Block can comprise is fixed, therefore after the quantity of the ACK/NACK channel of having determined to reserve, just can determine the Resource Block that need take; Wherein, when the embodiment of the invention need take two and above Resource Block at the ACK/NACK channel of reserving, suppose that at least one above-mentioned Resource Block comprises first Resource Block and at least one second Resource Block;

Step 103, the ACK/NACK channel that will need to reserve are divided into first group of ACK/NACK channel and at least one second group of ACK/NACK channel;

Because the number of packet that adopts different packet modes to obtain may be different, therefore the quantity of second group of ACK/NACK channel is at least one;

Wherein, the embodiment of the invention can be divided into groups to the ACK/NACK channel of reserving according to ACK/NACK channel number of repetition, be about to all ACK/NACK channels that just pass and be divided into one group, all ACK/NACK channels that retransmit for the first time are divided into one group, all ACK/NACK channels that retransmit for the second time are divided into one group, and the rest may be inferred; Particularly, that group that the ACK/NACK channel that just passes can be divided into is as first group of ACK/NACK channel, also that group that the ACK/NACK channel that retransmits for the last time can be divided into is as first group of ACK/NACK channel, that group that the ACK/NACK channel of other times re-transmission can certainly be divided into is as first group of ACK/NACK channel, and the embodiment of the invention does not limit; Suppose to comprise that just passing the ACK/NACK channel has needs repetition 4 times altogether, then the ACK/NACK channel of reserving can be divided into four groups;

The embodiment of the invention can also be divided into groups according to the CFI value, be about to the corresponding ACK/NACK channel of each CFI value and be divided into one group, particularly, can divide into groups according to CFI value order from small to large: with the CFI value is that the ACK/NACK channel that need take in 1 o'clock is divided into 1 group, with the CFI value is that to deduct the CFI value be that ACK/NACK channel behind the ACK/NACK channel that need take in 1 o'clock is divided into 1 group for the ACK/NACK channel that need take in 2 o'clock, with the CFI value be the ACK/NACK channel that need take in 3 o'clock to deduct the CFI value be that ACK/NACK channel behind the ACK/NACK channel that need take in 2 o'clock is divided into 1 group, the rest may be inferred; Wherein, first group of ACK/NACK channel can be corresponding with the CFI value of minimum or corresponding with the CFI value of maximum, can certainly be corresponding with other CFI value, and the embodiment of the invention does not limit; Suppose that maximum CFI value is 3, can be 1,2,3 situation according to the CFI value then be divided into 3 groups with the ACK/NACK channel of reservation;

Further, after the ACK/NACK channel that will reserve divides into groups according to CFI value, can be further with first group of ACK/NACK channel obtaining according to ACK/NACK channel number of repetition be divided into ACK/NACK channel group, second group of ACK/NACK channel is divided into the 2nd ACK/NACK channel according to ACK/NACK channel number of repetition and organizes; Suppose that the CFI value is that the ACK/NACK channel that need take is first group of ACK/NACK channel at 1 o'clock, then can further first group of ACK/NACK channel be divided into ACk/NACK channel group according to ACK/NACK channel number of repetition, suppose that ACK/NACK channel number of repetition is 3 times, then first group of ACK/NACK channel can be divided into 3 the one ACK/NACK channel groups;

Step 104, with first group of ACK/NACK channel and second group of ACK/NACK channel serial number at least one Resource Block.

Wherein, if at least one Resource Block is first Resource Block and at least one second Resource Block, then first group of ACK/NACK channel and second group of ACK/NACK channel are specially in serial number at least one Resource Block: the serial number on described first Resource Block and second Resource Block with first group of ACK/NACK channel and second group of ACK/NACK channel has at least a Resource Block not comprise ACK/NACK channel in first group of ACK/NACK channel and the second group of ACK/NACK channel in first Resource Block and second Resource Block.Need to prove, mainly comprise that with at least one Resource Block first Resource Block and second Resource Block are described in the embodiment of the invention, but be not that at least one Resource Block that limits in the embodiment of the invention must wealthy first Resource Block and second Resource Block.

Because first group of ACK/NACK channel and second group of ACK/NACK channel serial number on first Resource Block and second Resource Block, therefore after first group of ACK/NACK channel is numbered, just second group of ACK/NACK channel is numbered, therefore in first Resource Block and second Resource Block, has at least a Resource Block can not comprise ACK/NACK channel in first group of ACK/NACK channel and the second group of ACK/NACK channel simultaneously.

After the ACK/NACK channel packet that will reserve, first group of ACK/NACK channel after then will dividing into groups and second group of ACK/NACK channel serial number on first Resource Block and second Resource Block, according to the mode difference to the ACK/NACK channel packet reserved, the order of serial number also can be different:

When the ACK/NACK channel of reserving divides into groups according to ACK/NACK channel number of repetition, then can be earlier the group at the ACK/NACK channel place of first biography be numbered, the group to the ACK/NACK channel place that retransmits for the first time is numbered then, and the rest may be inferred; Earlier which group ACK/NACK channel is not numbered when certainly, the embodiment of the invention does not limit first group of ACK/NACK channel and second group of ACK/NACK channel carried out serial number; Wherein, the ACK/NACK channel after a kind of numbering of the embodiment of the invention can be as shown in table 1:

Resource Block

In the table 1, just the ACK/NACK channel that passes is first group of ACK/NACK channel, and the ACK/NACK channel that retransmits is second group of ACK/NACK channel with the ACK/NACK channel that retransmits for the second time for the first time; Wherein, the numbering away from the ACK/NACK channel of PUSCH Resource Block is more little more.

Perhaps the ACK/NACK channel after the numbering also can be as shown in table 2:

Table 2

In the table 2, the ACK/NACK channel that retransmits is first group of ACK/NACK channel for the second time, and just the ACK/NACK channel that passes is second group of ACK/NACK channel with the ACK/NACK channel that retransmits for the first time; Wherein, the numbering away from the ACK/NACK channel of PUSCH Resource Block is more little more.

When the ACK/NACK channel of reserving divides into groups according to the CFI value, then can with first group of ACK/NACK channel and second group of ACK/NACK channel according to the CFI value from the minimum to the maximum order or the CFI value from being up to minimum order serial number on first Resource Block and second Resource Block, promptly can number residing group of the ACK/NACK channel that the CFI value hour need take earlier, also can number residing group of the ACK/NACK channel that the CFI value need take when maximum earlier; ACK/NACK channel after a kind of numbering of the embodiment of the invention can be as shown in table 3:

Table 3

In the table 3, the ACK/NACK channel of CFI=1 is first group of ACK/NACK channel, the ACK/NACK channel that deducts in the ACK/NACK channel of CFI=2 behind the ACK/NACK channel of CFI=1 is second group of ACK/NACK channel, and the ACK/NACK channel that deducts in the ACK/NACK channel of CFI=3 behind the ACK/NACK channel of CFI=2 also is second group of ACK/NACK channel; Wherein, the numbering away from the ACK/NACK channel of PUSCH Resource Block is more little more.

Perhaps the ACK/NACK channel after the numbering also can be as shown in table 4:

Table 4

In the table 4, the ACK/NACK channel that deducts in the ACK/NACK channel of CFI=3 behind the ACK/NACK channel of CFI=2 is first group of ACK/NACK channel, the ACK/NACK channel of CFI=1 is second group of ACK/NACK channel, and the ACK/NACK channel that deducts in the ACK/NACK channel of CFI=2 behind the ACK/NACK channel of CFI=1 is second group of ACK/NACK channel; Wherein, the numbering away from the ACK/NACK channel of PUSCH Resource Block is more little more.

Further, if first group of ACK/NACK channel and second group of ACK/NACK channel have been divided into ACK/NACK channel group according to ACK/NACK channel number of repetition, then when first group of ACK/NACK channel is numbered, can first group of ACK/NACK channel be numbered according to the order of ACK/NACK channel group, equally, when second group of ACK/NACK channel is numbered, can be numbered according to first group of ACK/NACK channel of order of the 2nd ACK/NACK channel group; Particularly, so that being numbered according to the order of ACK/NACK channel group, first group of ACK/NACK channel be example, the order of the ACK/NACK channel that can retransmit from the ACK/NACK channel of first biography to high order first group of ACK/NACK channel or carry out serial number for ACK/NACK channel to the order of the ACK/NACK channel that just passes that retransmits from high order.At this moment, the ACK/NACK channel after a kind of numbering that provides of the embodiment of the invention can be as shown in table 5:

Table 5

In the table 5, the ACK/NACK channel of CFI=1 is first group of ACK/NACK channel, the ACK/NACK channel that deducts in the ACK/NACK channel of CFI=2 behind the ACK/NACK channel of CFI=1 is second group of ACK/NACK channel, and the ACK/NACK channel that deducts in the ACK/NACK channel of CFI=3 behind the ACK/NACK channel of CFI=2 also is second group of ACK/NACK channel; Wherein, the ACK/NACK channel of the ACK/NACK channel of the first biography under the ACK/NACK channel of CFI=1, the ACK/NACK channel that retransmits for the first time and re-transmission for the second time is an ACK/NACK channel group; Deducting ACK/NACK channel, the ACK/NACK channel that retransmits for the first time of the first biography under the ACK/NACK channel behind the ACK/NACK channel of CFI=1 and the ACK/NACK channel that retransmits for the second time in the ACK/NACK channel of CFI=2 is the 2nd ACK/NACK channel group, and deducting ACK/NACK channel, the ACK/NACK channel that retransmits for the first time of the ACK/NACK channel first biography down behind the ACK/NACK channel of CFI=2 and the ACK/NACK channel that retransmits for the second time in the ACK/NACK channel of CFI=3 also is that the 2nd ACK/NACK channel is organized.Wherein, the numbering away from the ACK/NACK channel of PUSCH Resource Block is more little more.

Perhaps the ACK/NACK channel after the numbering also can be as shown in table 6:

Table 6

In the table 6, the ACK/NACK channel that deducts in the ACK/NACK channel of CFI=3 behind the ACK/NACK channel of CFI=2 is first group of ACK/NACK channel, the ACK/NACK channel of CFI=1 is second group of ACK/NACK channel, and the ACK/NACK channel that deducts in the ACK/NACK channel of CFI=2 behind the ACK/NACK channel of CFI=1 is second group of ACK/NACK channel; Wherein, the ACK/NACK channel of the ACK/NACK channel of the first biography under the ACK/NACK channel of CFI=3, the ACK/NACK channel that retransmits for the first time and re-transmission for the second time is an ACK/NACK channel group; The ACK/NACK channel of the first biography under the ACK/NACK channel of CFI=1 and the ACK/NACK channel of CFI=2, the ACK/NACK channel that retransmits for the first time and the ACK/NACK channel that retransmits for the second time are the 2nd ACK/NACK channel group.Wherein, the numbering away from the ACK/NACK channel of PUSCH Resource Block is more little more.

From the above, present embodiment can divide into groups the ACK/NACK channel of reserving, and serial number at least one Resource Block with first group of ACK/NACK channel and second group of ACK/NACK channel, thereby making every group of ACK/NACK channel all is continuous in Resource Block, and because the quantity of the ACK/NACK channel of reserving is to determine according to the CFI value of maximum, when current CFI value is not the CFI value of maximum, then the ACK/NACK channel of some group does not need to use, the Resource Block that just can organize that does not need to use the ACK/NACK channel occupancy this moment discharges, thereby can improve the utilization ratio of Resource Block; Further, when the more group of ACK/NACK channel quantity that will take is placed on the aft section of integral body of first Resource Block and second Resource Block, if this group ACK/NACK channel does not need to be used, then can discharge the more resources piece, further improve the utilization ratio of Resource Block.

Further, the embodiment of the invention may further include following steps with described first group of ACK/NACK channel and second group of ACK/NACK channel after serial number at least one Resource Block: the situation that the ACK/NACK channel that transmission is reserved needs distributes; Wherein, the situation that the ACK/NACK channel that needs are reserved distributes can comprise following information: reserve the CFI value that the ACK/NACK channel is adopted, the mode of grouping, the mode etc. of numbering, thus make user terminal can be defined as the numbering (numbering that comprises the ACK/NACK channel of the numbering of the first ACK/NACK channel of biography and re-transmission) of the own ACK/NACK channel that distributes according to these information; Perhaps, if this step sends after the solicited message that receives user terminal, the situation that the ACK/NACK channel that needs are reserved distributes also can comprise: the numbering of the ACK/NACK channel that distributes for this user terminal, thus make this user terminal can be retrieved as the numbering of the ACK/NACK channel of own distribution.

Followingly introduce the method for channel allocation embodiment two that the embodiment of the invention provides, method for channel allocation embodiment two is described the method for channel allocation that this aspect embodiment provides from the angle of instantiation, needs the parameter and the definition thereof of using earlier in the description embodiment of the invention:

The ACK/NACK maximum transmission times that D expresses support for, common 1≤D≤3, D=3 represents that ACK/NACK can also transmit 3 times again except that first biography;

D represents the current the number of transmissions of ACK/NACK, d=0, and 1 ..., D-1;

CCE _dRepresent that the d time ACK/NACK transmits the minimum CCE number that corresponding PDCCH takies, the invention process example assumes CCE ₀=1, CCE ₁=4, CCE ₂=8.

n _CCEThe initial CCE label that expression PDCCH takies;

N _{CCE, n}CCE number when expression CFI value is n, and definition N _{CCE, 0}=0, n={0,1,2,3};

N _PUCCH ⁽¹⁾Be expressed as the biasing of the ACK/NACK channel of implicit expression mapping reservation, dispose by high level;

n _PUCCH ^{(1, d)}The ACK/NACK channel label that the initial CCE label implicit expression mapping that expression is taken by PDCCH obtains;

INT () represents rounding operation, specifically can be round up computing or downward rounding operation;

In addition, the ACK/NACK channel of hypothesis sub-district is pressed the CFI=3 maximum configured in the embodiment of the invention, is 3 but the embodiment of the invention does not limit the maximum of CFI.

The method for channel allocation that the embodiment of the invention provides can be done following distribution with the ACK/NACK channel of dynamic assignment:

Definite process that needs the ACK/NACK channel quantity of reservation:

The first ACK/NACK channel (d=0) that passes: the corresponding ACK/NACK channel of each CCE, the ACK/NACK channel of the user uplink by the implicit distribution of user's PDCCH sequence number.Suppose descending one total N _{CCE, 3}Individual CCE, the ACK/NACK channel that passes at the beginning of then corresponding the keeping for is N _{CCE, 3}Individual.

The ACK/NACK channel of maximum re-transmission is reserved in a sub-district, as retransmit the ACK/NACK channel reservation N of (d=1) for secondary _{CCE, 3}/ CCE ₁Individual channel is the ACK/NACK channel reservation N of three re-transmissions (d=2) _{CCE, 3}/ CCE ₂Individual channel.Wherein, the ACK/NACK channel number of reservation can both know UE all in the sub-district by Dynamic Broadcast Channel broadcasting or predefined mode.For example, the repeated configuration information of some users' ACK/NACK channel can be informed this user in the following way: by Radio Resource control (RRC) signaling user of high level; By the CCE number that the descending PDCCH of user takies, implicit expression notify the user; Wherein, whether repeated configuration information can comprise needs repetition, repeats several inferior information.

Then need the ACK/NACK channel of reservation to be altogether in a sub-district Individual.

Grouping process:

The ACK/NACK channel of needs being reserved according to the CFI value divides in groups, particularly, passes through n _CCEJudge that the ACK/NACK channel after the mapping belongs to that group corresponding with the CFI value, deterministic process is from n={1, and 2, select n to satisfy N among the 3} _{CCE, n-1}≤ n _CCE＜N _{CCE, n}, then be assigned to the n group;

According to just passing the ACK/NACK channel, secondary retransmits the ACK/NACK channel again, three re-transmission ACK/NACK channels ...., every group of ACK/NACK channel will be divided into different ACK/NACK channel groups;

The numbering process:

Every group of ACK/NACK channel carried out serial number, particularly, can number the group of n=1 earlier, number the group of n=2 again, number the group of n=3 at last; Wherein, in the process that every group of ACK/NACK channel is numbered, earlier first biography ACK/NACK channel being numbered, again secondary being retransmitted the ACK/NACK channel and be numbered, is that three re-transmission ACK/NACK channels are numbered then, and the like; Wherein, the ACK/NACK channel after a kind of numbering of the embodiment of the invention can be as shown in table 5.

Wherein, above-mentioned assigning process can be with following mapping formulate:

$n_{\mathrm{PUCCH}}^{(1,d)}=\underset{i=1}{\overset{d-1}{\mathrm{\Σ}}}\mathrm{INT}(N_{\mathrm{CCE},n}/{\mathrm{CCE}}_i)+\underset{i=d+1}{\overset{D-1}{\mathrm{\Σ}}}\mathrm{INT}(N_{\mathrm{CCE},n-1}/{\mathrm{CCE}}_i)+n_{\mathrm{CCE}}/{\mathrm{CCE}}_d+N_{\mathrm{PUCCH}}^{\left(1\right)},$ N={1 wherein, 2,3};

In order not influence the ACK/NACK channel of the sub-district of not supporting that ACK repeats, the ACK/NACK maximum transmission times D that can allow Cell Broadcast CB support.D=1 represents not support ACK to repeat, at this moment d=0, CCE _d=1, following formula is reduced to automatically $n_{\mathrm{PUCCH}}^{\left(1\right)}=n_{\mathrm{CCE}}+N_{\mathrm{PUCCH}}^{\left(1\right)}.$ Perhaps whether Cell Broadcast CB supports ACK to repeat, and is an identical preset value for the sub-district D that supports ACK to repeat.Promptly do not support sub-district that ACK repeats can obtain the formula the same with existing standard by the simplification of formula.

When supposing CFI=1, CCE is 8; During CFI=2, CCE is 19; During CFI=3, CCE is 36;

Suppose that there is the situation of CFI=3 in a certain period, the configuration of the ACK/NACK channel of dynamic broadcast information broadcast CFI=3: three Resource Block are as the ACK/NACK channel of sub-district, 50 ACK/NACK channels altogether altogether;

Need to reserve the ACK/NACK channel number altogether

If a Resource Block comprises 18 ACK/NACK channels, then need 3 Resource Block altogether.

Sub-district ACK/NACK channel number:

During CFI=1, just the ACK/NACK channel 0-7 that passes is corresponding to CCE0-7, and once the ACK/NACK channel 8,9 of Chong Chuaning is corresponding to CCE0, CCE4, and the ACK/NACK channel 10 of secondary re-transmission is corresponding to CCE0;

During CFI=2, just the ACK/NACK channel 11-21 that passes is corresponding to CCE8-18, and the ACK/NACK channel 22,23,24 that once retransmits is corresponding CCE8 respectively, CCE12, and CCE16, the ACK/NACK channel 25,26 that secondary retransmits is corresponding CCE8 respectively, CCE16;

During CFI=3, just the ACK/NACK channel 27-43 that passes is corresponding to CCE19-35, once the ACK/NACK channel 44,45 of Chong Chuaning, the corresponding CCE20 of 46,47 difference, CCE24, CCE28, CCE32, the ACK/NACK channel 48,49 that secondary retransmits is corresponding CCE24 respectively, CCE32.

Suppose that UE is needed repetition by the configuration of RRC signaling, repeats once, i.e. d=1; UE reads the PCFICH of some subframes, obtains the CFI value, and default is CFI=2; UE reads eNodeB and sends to its PDCCH, supposes n _CCE=16; Then according to above-mentioned distribution, UE can know that the own ACK/NACK that just passes is assigned with the ACK/NACK channel No. 19, and the ACK/NACK of re-transmission is assigned with the ACK/NACK channel No. 24.
