Step 106：The feedback information group after sending coding.

On the basis of embodiment shown in Fig. 1, the embodiment of the invention provides it is a kind of send feedback information method, Referring to fig. 2, this method includes：

Step 201：Base station receives the upstream data that UE is sent；

Wherein, UE receives the scheduling information that base station is sent, and sends upstream data to base station according to the scheduling information.

Wherein, base station transmits scheduling information to UE in the first subframe, sends upstream data to dispatch UE, the first subframe can Think that any subframe, scheduling information may include the information such as resource used in the upstream data and modulation coding scheme.

Wherein, UE receives the scheduling information, and upstream data is sent according to the scheduling information in the second subframe to base station, The number of sub-frames being separated by between first subframe and the second subframe is the integral multiple of default value.For example, it is assumed that the first subframe is son Frame n, default value 4, then the second subframe can be subframe n+4 or subframe n+8 etc..In altogether, in embodiments of the present invention, preset Numerical value is 4 only for example, this is not as limiting the scope of the invention, and default value can be other integers, It such as can be 5 or 6 integers.

Wherein, base station can send scheduling information to multiple UE in the first subframe, after each UE receives the scheduling information, Upstream data can be sent in the second subframe respectively to base station.

Step 202：Base station determines that the first loaded length, the first loaded length are at least two load in loaded length set One of length；

Wherein, base station can determine the first loaded length by one of at least following three kinds of modes, including：

The first, the quantity of the base station corresponding feedback information of upstream data based on the received is determined from loaded length set A kind of loaded length is as the first loaded length.

Wherein, the quantity of the base station corresponding feedback information of upstream data based on the received, selects from loaded length set One is greater than or equal to the loaded length of the quantity, using the loaded length selected as the first loaded length.

Preferably, base station selects minimum load length from the loaded length for being greater than or equal to the quantity, most by selection Side crops industry length is as the first loaded length.

For example, it is assumed that in loaded length set include two kinds of loaded lengths, respectively 4 and 6, the received upper line number in base station Quantity according to corresponding feedback information is 3, then base station selects the load for being greater than or equal to the quantity 3 from loaded length set Lotus length 4.

The second, base station determines that a kind of loaded length is long as the first load from loaded length set according to the mark of UE Degree.

Specifically, base station is according to the number of the loaded length for including in loaded length set, to needing to send feedback information Each UE mark carry out modulo operation, obtain the modulus of each UE, it is long from load if the modulus of each UE is identical It is the loaded length of the modulus as the first loaded length that location index is selected in degree set.

For example, it is desired to which the UE for sending feedback information includes UE1, UE2 and UE3, the mark of UE1, UE2 and UE3 are respectively 2,4 With 8, the number for the loaded length for including according to loaded length set is 2, respectively to the mark of UE1 2, the mark of UE2 4 and UE3 Mark 8 carry out modulo operation, the modulus for obtaining the modulus of UE1, the modulus of UE2 and UE3 is all 0, from loaded length set Location index is selected to be used as the first loaded length for the loaded length 4 of the modulus 0.

The index or received upstream data of third, base station resource according to used in the scheduling information of dispatching uplink data The index of used resource, a kind of loaded length of determination is as the first loaded length from loaded length set.

Wherein, the index of base station resource according to used in the scheduling information of dispatching uplink data, from loaded length set A kind of middle loaded length of determination is as the first loaded length, Ke Yiwei：

Base station is according to the number of the loaded length for including in loaded length set, respectively to each tune of scheduling upstream data The index for spending resource used in information carries out modulo operation, the modulus of each scheduling information is obtained, if each scheduling information Modulus it is all identical, then select location index long as the first load for the loaded length of the modulus from loaded length set Degree.

For example, each scheduling information of dispatching uplink data is respectively scheduling information 1,2 and 3, and dispatching uplink data The index of scheduling information 1,2 and 3 used resources is respectively 12,14 and 18, the loaded length for including according to loaded length set Number 2, provided used in the index 12 of resource, scheduling information 2 used in the scheduling information 1 to scheduling upstream data respectively The index 18 of resource used in the index 14 and scheduling information 3 in source carries out modulo operation, obtains the modulus of scheduling information 1, adjusts The modulus of the modulus and scheduling information 3 of spending information 2 is all 0, selects location index for the load of the modulus 0 from loaded length set Lotus length 4 is used as the first loaded length.Alternatively,

Wherein, the index of base station resource used in upstream data based on the received, determines one from loaded length set Kind loaded length is as the first loaded length, Ke Yiwei：

Base station is according to the number of the loaded length for including in loaded length set, respectively to received each upstream data institute The index of the resource used carries out modulo operation, the modulus of each upstream data is obtained, if the modulus of each upstream data Identical, then it is the loaded length of the modulus as the first loaded length that location index is selected from loaded length set.

For example, received each upstream data is respectively upstream data 1,2 and 3, and upstream data 1,2 and 3 uses money The index in source is respectively 18,22 and 30, according to the number 2 for the loaded length that loaded length set includes, respectively to upstream data 1 The rope of resource used in the index 22 and upstream data 3 of resource used in the index 18 of used resource, upstream data 2 Drawing 30 carry out modulo operations, the modulus for obtaining the modulus of upstream data 1, the modulus of upstream data 2 and upstream data 3 is all 0, from Location index is selected to be used as the first loaded length for the loaded length 4 of the modulus 0 in loaded length set.

Wherein, carrying what lengths sets can be prior preset loaded length set, or determine the first load Determine a loaded length set before length in multiple loaded length set existing for local as base station.

Wherein, base station receives the upstream data that UE is sent in the second subframe, and sends the upstream data pair in third subframe The feedback information answered, the number of sub-frames being separated by between third subframe and the second subframe are the integral multiple of default value.For example, second Subframe is subframe n+4, and default value 4, third subframe can be subframe n+8 or subframe n+12 etc..

Wherein, if base station is successfully received the upstream data of UE transmission, base station needs to be sent to line number on this of UE It can be ACK according to corresponding feedback information, if base station is not successfully receiving the upstream data of UE transmission, base station needs to send out The corresponding feedback information of the upstream data for giving UE can be NACK.

Wherein, in embodiments of the present invention, base station can first determine the first loaded length, then receive the upper line number of UE transmission According to the upstream data of UE transmission can also first being received, then determine the first loaded length, so two not stringent timing of operation Relationship.

Preferably, base station is by the identification notification of the first loaded length to UE, Ke Yiwei：

Base station sends signaling to UE, which carries the mark of the first loaded length, which includes 1 signaling of layer or layer 2 Signaling.

Preferably, base station can configure loaded length by high-level signaling in UE.

Step 203：Base station determines location index of the corresponding feedback information of received upstream data in feedback information group, The length of the feedback information group is the first loaded length；

Wherein, base station can determine the corresponding feedback letter of received upstream data by one of at least following three kinds of modes The location index in feedback information group is ceased, including：

The first, base station is according to the RNTI of UE（Radio Network Temporary Identity, wireless network are temporarily marked Know）, determine location index of the corresponding feedback information of upstream data of UE transmission in feedback information group；

Specifically, base station carries out modulo operation to the RNTI of UE and obtains the modulus of the UE, by this according to the first loaded length Location index of the modulus as the corresponding feedback information of upstream data that the UE is sent in feedback information group.

For example, it is assumed that the first loaded length is 4, the UE for needing to send feedback information includes UE1,2 and 3, and UE1,2 and 3 RNTI be respectively 8,9 and 10, then base station is according to the first loaded length 4, respectively to the RNTI that the RNTI of UE1 is 8, UE2 be 9 with And the RNTI of UE3 is 10 progress modulo operations, the modulus for obtaining UE1 is 0, the modulus of UE2 is 1 and the modulus of UE3 is 2, will The modulus of UE1 is 0 as location index of the corresponding feedback information of upstream data in feedback information group of UE1 transmission, by UE2 Modulus be 1 as location index of the corresponding feedback information of upstream data in feedback information group of UE2 transmission and by UE3 Modulus be 2 location index of the corresponding feedback information of upstream data in feedback information group as UE3 transmission.

The second, the index of base station resource used in upstream data based on the received, determines that received upstream data is corresponding Location index of the feedback information in feedback information group.

Specifically, base station takes the index of resource used in received upstream data according to the first loaded length Modular arithmetic obtains the corresponding modulus of received upstream data, using the corresponding modulus of received upstream data as received upper line number According to location index of the corresponding feedback information in feedback information group.

For example, it is assumed that the first loaded length is 4, received upstream data includes upstream data 1,2 and 3, and upstream data The index of resource used in 1 is 8, and the index of resource used in upstream data 2 is money used in 9 and upstream data 3 The index in source is 10, then base station is according to the first loaded length 4, respectively to the index 8 of resource used in upstream data 1, uplink The index 10 of resource used in the index 9 and upstream data 3 of resource used in data 2 carries out modulo operation, obtains The modulus of row data 1 is 0, the modulus of upstream data 2 is 1 and the modulus of upstream data 3 is 2, and the modulus by upstream data 1 is 0 as location index of the corresponding feedback information of upstream data 1 in feedback information group, by the modulus 1 of upstream data 2 as upper Location index of the corresponding feedback information of row data 2 in feedback information group and the upper line number of the conduct of modulus 2 by upstream data 3 According to location index of the 3 corresponding feedback informations in feedback information group.

The index of third, the resource according to used in the scheduling information of the upstream data of scheduled reception, determines on received Location index of the corresponding feedback information of row data in feedback information group.

Specifically, base station is provided according to the first loaded length to used in the scheduling information for dispatching received upstream data The index in source carries out modulo operation, the modulus of the scheduling information is obtained, using the modulus of the scheduling information as the scheduling information tune Location index of the corresponding feedback information of the upstream data of degree in feedback information group.

For example, it is assumed that the first loaded length is 4, received upstream data includes upstream data 1,2 and 3, and dispatching uplink The index of resource used in the scheduling information of data 1 is 4, the rope of resource used in the scheduling information of dispatching uplink data 2 Be cited as 9 and dispatching uplink data 3 scheduling information used in resource index be 10, then base station is according to the first loaded length 4, respectively to the index 8 of resource used in the scheduling information for dispatching upstream data 1, the scheduling information institute of dispatching uplink data 2 The index 10 of resource used in the index 9 of the resource used and the scheduling information of dispatching uplink data 3 carries out modulo operation, The modulus for obtaining the scheduling information of dispatching uplink data 1 is 0, the modulus of the scheduling information of dispatching uplink data 2 is 1 and scheduling The modulus of the scheduling information of upstream data 3 is 2, and the modulus 0 of the scheduling information of dispatching uplink data 1 is right as upstream data 1 Location index of the feedback information answered in feedback information group regard the modulus 1 of the scheduling information of dispatching uplink data 2 as uplink Location index of the corresponding feedback information of data 2 in feedback information group and by the mould of the scheduling information of dispatching uplink data 3 Location index of the number 2 as the corresponding feedback information of upstream data 3 in feedback information group.

Further, location index of the corresponding feedback information of upstream data that base station sends UE in feedback information group It notifies to UE, Ke Yiwei：

Send RRC（Radio Resource Control, wireless heterogeneous networks）Proprietary signaling is to UE, the proprietary letter of the RRC The mark for carrying the location index is enabled, so that UE obtains the location index according to the proprietary signaling of the RRC；And/or

Send demodulated reference signal cyclic shift field of the scheduling information of dispatching uplink data to UE, in the scheduling information Carry the location index.

Wherein, in embodiments of the present invention, base station can select a field from scheduling information, and the field of selection is arranged Carry the location index.Preferably, the demodulated reference signal cyclic shift field in the base station selected scheduling information.

Wherein, in embodiments of the present invention, the reserved field that can be used in the proprietary signaling of RRC carries the location index Mark, alternatively, increasing a newer field in the proprietary signaling of RRC, which carries the mark of the location index.

Step 204：Base station location index of the corresponding feedback information of upstream data in feedback information group based on the received, Received upstream data is mapped in feedback information group respectively；

For example, location index 0 of the base station according to the corresponding feedback information of upstream data 1 in feedback information group, by uplink Data 1 are mapped in feedback information group on corresponding position；According to the corresponding feedback information of upstream data 2 in feedback information group Location index 1, upstream data 2 is mapped in feedback information group on corresponding position；And it is corresponding according to upstream data 3 Location index 2 of the feedback information in feedback information group, upstream data 3 is mapped to corresponding position in feedback information group On.

Preferably, if there is also the clear positions of non-mapped feedback information in the feedback information group, in spare bits Set mapping predetermined bit.

Wherein, predetermined bit can be bit 0 or bit 1.For example, the first loaded length is 4, the length of feedback information group It for the first loaded length 4, i.e., include 4 positions in the feedback information group, 0,1 and 2 point of location index in the feedback information group Not corresponding position is all mapped with feedback information, and the corresponding position of location index 3 is clear position, therefore right in location index 3 Predetermined bit is mapped on the position answered.

Step 205：Base station carries out combined coding to the feedback information group according to the first loaded length, anti-after being encoded Feedforward information group；

Step 206：Base station sends the feedback information group after coding.

It is preferential, base station can the resource according to used in the scheduling information of the upstream data of scheduled reception, determination is used for The running time-frequency resource of feedback information group after sending coding；Then the feedback information after coding is sent on determining running time-frequency resource Group.

Wherein, in embodiments of the present invention, resource used in scheduling information is made with feedback information group is sent in advance Running time-frequency resource is bound；Correspondingly, base station obtains and money used in the scheduling information of the upstream data of scheduled reception The running time-frequency resource of source binding, the running time-frequency resource that will acquire are determined as the running time-frequency resource for sending the feedback information group after encoding, Such base station does not need to notify the running time-frequency resource for being used to send the feedback information group after coding to UE, can simplify design with And save expense.

Wherein, base station is after receiving the upstream data that UE is sent, if it is determined that does not send the corresponding feedback of the upstream data It when information is to UE, sends a notification message to UE, the notification message is for notifying UE not send the feedback information of the upstream data.

Wherein, if the number of the corresponding feedback information of upstream data is smaller, base station can not send feedback information first It to UE, and notifies UE, UE is so avoided to detect in third subframe and receives the feedback information of mistake.

Wherein, in embodiments of the present invention, it after base station receives the upstream data that UE is sent, can first determine the need for anti- Present the corresponding feedback information of the upstream data, if it is determined that need to feed back the corresponding feedback information of the upstream data, it is determined that the One loaded length determines location index of the corresponding feedback information of received upstream data in feedback information group, according to the position Index is set, the corresponding feedback information of the upstream data is mapped in feedback information group, according to the first loaded length to the feedback Information group carries out combined coding, the feedback information group after sending coding.If it is determined that not needing to feed back upstream data correspondence Feedback information, then notify the UE not send the corresponding feedback information of the upstream data to the UE.

Wherein, base station determines the need for feeding back the corresponding feedback information of the upstream data, may include：

It determines the need for feeding back the upstream data according to the quantity of the corresponding feedback information of current upstream data corresponding Feedback information.

Specifically, if when the quantity of the current corresponding feedback information of upstream data is less than threshold value, for example only need to feed back The feedback information of one or two UE, and the feedback information of each UE is 1 or 2 bit, is not fed back then base station can determine The corresponding feedback information of the upstream data；If the quantity of the corresponding feedback information of current upstream data is greater than threshold value, open Move the sending method of the feedback information of above-mentioned combined coding.

The program can make resource utilization higher, i.e., when the feedback information for needing to feed back is few, do not have to using upper The scheme for stating combined coding saves resource overhead, and influences smaller, the i.e. notice that these individual UE can receive base station to UE Feedback information is not sent, then these individual UE will not go to receive corresponding feedback information, therefore not will cause erroneous detection.

Optionally, base station can also be according to the down load situation in current system to determine whether needing to feed back the uplink The corresponding feedback information of data can specifically be judged according to the load of control channel or data channel, for example, if current The heavier loads of control channel, so that above-mentioned feedback information is sent without running time-frequency resource or power resource, even when currently The quantity of feedback information is more, can not also feed back above-mentioned feedback information.It is, of course, also possible to judged according to other information, this In and without limitation.

In embodiments of the present invention, the corresponding feedback information of multiple upstream datas can be mapped in feedback information group, Combined coding is carried out to the corresponding feedback information of the multiple upstream datas for including in the feedback information group, coding can be reduced and opened Pin, and improve coding gain；In addition, due to determining the first loaded length, and the length of the feedback information group is the first load Length can make the first determining loaded length be equal to the number of the corresponding feedback information of upstream data as far as possible, thus can subtract The number of the clear position of non-mapped feedback information, reduces the resource of transmitting feedback information in few feedback information group, improves and passes The reliability and reduction overhead of defeated feedback information；As base station according to used in the RNTI of UE, received upstream data The index of resource used in the scheduling information of the upstream data of the index or scheduled reception of resource, determines received upstream data Location index of the corresponding feedback information in feedback information group, so that base station does not need to notify the location index to UE, it can Overhead is designed and further reduced to simplify.

Referring to Fig. 3, the embodiment of the invention provides a kind of methods for receiving feedback information, including：

Step 301：Upstream data is sent to base station；

Step 302：Receive the feedback information group that base station is sent；

Step 303：Corresponding first loaded length of the feedback information group is determined from loaded length set, wherein the load Lotus lengths sets include at least two loaded lengths；

Step 304：Determine location index of the corresponding feedback information of the upstream data in the feedback information group；

Step 305：According to the first loaded length, which is decoded, and according to the location index from translating The corresponding feedback information of the upstream data is obtained in feedback information group after code.

In embodiments of the present invention, due to determining that corresponding first load of feedback information group is long from loaded length set Degree, determines location index of the corresponding feedback information of upstream data in the feedback information group, such base station can be to the feedback The corresponding feedback information of the multiple upstream datas for including in information group carries out combined coding, can reduce encoding overhead, Yi Jiti High coding gain；In addition, due to determining the first loaded length, and the length of the feedback information group is the first loaded length, it can be with So that the first determining loaded length is equal to the number of the corresponding feedback information of upstream data as far as possible, thus feedback information can be reduced The number of the clear position of non-mapped feedback information in group reduces the resource of transmitting feedback information, improves transmitting feedback information Reliability and reduce overhead.

On the basis of embodiment shown in Fig. 3, the embodiment of the invention provides it is a kind of receive feedback information method, Referring to fig. 4, this method includes：

Step 401：UE sends upstream data to base station；

Wherein, UE receives the scheduling information of base station transmission in the first subframe, and the first subframe can be any subframe, the tune Spending information may include the information such as resource used in the upstream data and modulation coding scheme.According to the tune in the second subframe It spends information and sends upstream data to base station, the number of sub-frames being separated by between the first subframe and the second subframe is the integer of default value Times.For example, it is assumed that the first subframe is subframe n, default value 4, then the second subframe can be subframe n+4 or subframe n+8 etc..

Step 402：UE receives the feedback information group that base station is sent；

Wherein, UE sends upstream data to base station in the second subframe, and the feedback letter that base station is sent is received in third subframe Breath group includes the corresponding feedback information of the upstream data in the feedback information group.It is separated by between third subframe and the second subframe Number of sub-frames is the integral multiple of default value.For example, it is assumed that the second subframe is subframe n+4, default value 4, then third subframe It can be subframe n+8 or subframe n+12 etc..

Wherein, UE resource according to used in the scheduling information for dispatching the upstream data determines that base station sends feedback information Running time-frequency resource used in group；Then the feedback information group that base station is sent is received on determining running time-frequency resource.

Wherein, in embodiments of the present invention, resource used in scheduling information is made with feedback information group is sent in advance Running time-frequency resource is bound；It is bound correspondingly, UE obtains and dispatch resource used in the scheduling information of the upstream data Running time-frequency resource, the running time-frequency resource that will acquire be determined as send coding after feedback information group running time-frequency resource.

Wherein, in embodiments of the present invention, base station judges whether to send the uplink after receiving the upstream data that UE is sent The corresponding feedback information of data if it is judged that not sending the corresponding feedback information of the upstream data to UE, is then sent logical to UE Message is known to UE, and the notification message is for notifying UE not send the feedback information of the upstream data to the UE.

UE receives the notification message, and judges that base station does not send the corresponding feedback of the upstream data according to the notification message Information.

Wherein, when UE judges that base station does not send the corresponding feedback information of the upstream data, UE will not go to receive and correspond to Feedback information, therefore not will cause erroneous detection.

Step 403：UE determines corresponding first loaded length of the feedback information group from loaded length set, wherein carries Lotus lengths sets include at least two loaded lengths；

Wherein, UE can determine the first loaded length by one of at least following three kinds of modes, including：

The first, the mark for the first loaded length that UE is notified according to base station determines the first load from loaded length set Length.

Specifically, the signaling that base station is sent is received, which carries the mark of the first loaded length, which includes layer 1 2 signaling of signaling and/or layer, determines the first loaded length according to the mark of the first loaded length from loaded length set.

Above-mentioned 1 signaling of layer can be Physical Downlink Control Channel, for example dispatch the scheduling information of above-mentioned upstream data.Specifically , above-mentioned first loaded length can be notified by the cyclic shift field of the demodulated reference signal in above-mentioned scheduling information. 2 signaling of layer are specifically as follows media access signaling.

Wherein, loaded length set can be preset in UE in advance, can also be allocated to UE by high-level signaling by base station.

The second, UE determines the first loaded length according to itself mark from loaded length set.

Specifically, the number for the loaded length that UE includes according to loaded length set carries out modulus fortune to the mark of itself Calculation obtains modulus, location index loaded length identical with the modulus is selected from the loaded length set, by the load of selection Length is as the first loaded length.

For example, it is assumed that loaded length set includes 4 and 6 two kind of loaded length, UE's itself is identified as 2, then according to load The number 2 for the loaded length that lengths sets include carries out modulo operation to the mark 2 of itself and obtains modulus 0, from the loaded length Location index loaded length 4 identical with the modulus 0 is selected in set, by the loaded length 4 selected as the first loaded length.

Third, the index or the upstream data of UE resource according to used in the scheduling information for dispatching the upstream data are made The index of resource determines the first loaded length from loaded length set.

Specifically, UE is according to the number of the loaded length for including in loaded length set, to the tune for dispatching the upstream data Degree information used in resource index carry out modulo operation obtain modulus, from the loaded length set select location index with The identical loaded length of the modulus, using the loaded length selected as the first loaded length.Alternatively,

Specifically, UE carries out modulo operation to the RNTI of itself and obtains modulus according to the first loaded length, the mould that will be obtained Location index of the number as the corresponding feedback information of the upstream data in feedback information group.

For example, it is assumed that the RNTI of UE is 8, the first loaded length is 4, then UE is according to the first loaded length 4, to itself RNTI carries out modulo operation, and as 8 carry out modulo operation, obtains modulus 0, and obtained modulus 0 is corresponding as the upstream data Location index of the feedback information in feedback information group.

The index of third, UE resource according to used in the upstream data determines the corresponding feedback information of the upstream data Location index in feedback information group；

Specifically, UE carries out modulo operation to the index of resource used in the upstream data according to the first loaded length Modulus is obtained, the location index using obtained modulus as the corresponding feedback information of the upstream data in feedback information group.

For example, it is assumed that the index that UE sends the upstream data is 8, the first loaded length is 4, then UE is according to the first load Length 4 carries out modulo operation to the index 8 for sending the upstream data and obtains modulus 0, by obtained modulus 0 as line number on this According to location index of the corresponding feedback information in feedback information group.

4th, the index of UE resource according to used in the scheduling information for dispatching the upstream data, determines the upstream data Location index of the corresponding feedback information in feedback information group.

Specifically, UE is according to the first loaded length, to the rope of resource used in the scheduling information for dispatching the upstream data It introduces row modulo operation and obtains modulus, using obtained modulus as the corresponding feedback information of the upstream data in feedback information group Location index.

For example, it is assumed that the index for dispatching resource used in the scheduling information of the upstream data is 10, the first loaded length Be 4, then UE is according to the first loaded length 4, the index to resource used in the scheduling information for dispatching the upstream data be 10 into Row modulo operation obtains modulus 0, by obtained modulus 0 as the corresponding feedback information of the upstream data in feedback information group Location index.

Step 405：UE decodes the feedback information group, the feedback information decoded according to the first loaded length Group；

Step 406：Location index of the UE according to the corresponding feedback information of the upstream data in feedback information group, from decoding The corresponding feedback information of the upstream data is obtained in feedback information group afterwards.

In embodiments of the present invention, due to determining that corresponding first load of feedback information group is long from loaded length set Degree, determines location index of the corresponding feedback information of upstream data in the feedback information group, such base station can be to the feedback The corresponding feedback information of the multiple upstream datas for including in information group carries out combined coding, can reduce encoding overhead, Yi Jiti High coding gain；In addition, due to determining the first loaded length, and the length of the feedback information group is the first loaded length, it can be with So that the first determining loaded length is equal to the number of the corresponding feedback information of upstream data as far as possible, thus feedback information can be reduced The number of the clear position of non-mapped feedback information in group reduces the resource of transmitting feedback information, improves transmitting feedback information Reliability and reduce overhead；As the index of UE resource according to used in the RNTI of itself, the upstream data of transmission Or the index of resource used in the scheduling information of the upstream data is dispatched, determine the corresponding feedback information of the upstream data anti- Location index in feedforward information group can simplify design and into one so that base station does not need to notify the location index to UE Step ground reduces overhead.
