Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
As shown in Fig. 2 A, the system that the embodiment of the present invention sends feedback information comprises: network equipment 10 and terminal 20.
Terminal 20 is used for receiving the configuration information from network equipment 10, and sends feedback information according to the feedback system of configuration information indication.
After terminal 20 has been determined feedback system, receive from the downlink data packet of network side and it is carried out decoding, and according to the feedback system transferring ACK/NACK that determines.
In concrete enforcement, terminal 20 can be to network side reporting terminal 20 grades and/or ability at the beginning of connecting system, and network equipment 10 just can know according to terminal 20 grades and/or ability whether this terminal 20 supports the various feedback mode.
Such as can will whether supporting DFT-S-OFDM to can be used as a kind of UE ability, namely can report to network equipment 10 at the beginning of terminal 20 connecting systems, network equipment 10 just can send configuration information to this terminal 20 after determining that this terminal 20 is supported DFT-S-OFDM.
Wherein, network equipment 10 can be placed in high-level signaling with configuration information, and high-level signaling is sent to terminal 20.High-level signaling can be terminal rank (UE specific), such as dedicated signaling; Can also be cell level (cell specific), such as broadcast signaling.
In force, network equipment 10 can adopt various ways to determine to be specially terminal 20 needs which kind of feedback system of configuration, and the below is based on the PUCCH feedback system of DFT-S-OFDM and PUCCH format 1b with channel selection feedback system take feedback system and describes as example.
Always one, use PUCCH feedback system based on DFT-S-OFDM, that is to say no matter the current network resources situation how, all requires to support based on the terminal use of the PUCCH feedback system of the DFT-S-OFDM PUCCH feedback system based on DFT-S-OFDM.
Two, select the quantity of PUCCH format 1b with channelselection resource according to the channel of the quantity of current available PUCCH resource based on DFT-S-OFDM and current available use PUCCH format 1b form, need to determine the feedback system of configuration.Such as PUCCHformat 1b resource-constrained current in system, and there are a large amount of Rel-8 terminals to use PUCCH format 1b feeding back ACK/NACK, configurable CA (Carrier Aggregation, carrier aggregation) terminal (namely supporting the terminal based on the PUCCH of DFT-S-OFDM) is used the feedback system feeding back ACK/NACK based on the PUCCH of DFT-S-OFDM; Resource-constrained such as current PUCCH based on DFT-S-OFDM in system, 10 pairs of part CA terminal configuration of network equipment are used PUCCH Format 1b withchannel selection feedback system feeding back ACK/NACK.
Need to prove, the embodiment of the present invention is not limited to above-mentioned two schemes, and other can determine to need to adopt the scheme of which kind of feedback system is all to use the embodiment of the present invention.
Wherein, network equipment 10 can adopt implicit expression notice or explicit notification indicating terminal 20 to adopt which kind of feedback system.The below is introduced respectively.
Explicit notification:
Concrete, network equipment 10 determines that according to the feedback system that sets in advance and the corresponding relation of the first bit information needing first bit information corresponding to feedback system of configuration is configuration information, then sends to configuration information terminal 20; Accordingly, terminal 20 determines according to the corresponding relation of feedback system and the first bit information feedback system corresponding to the first bit information of receiving
Can set in advance the corresponding relation of feedback system and the first bit information under this mode, such as two kinds of feedback systems are arranged, can adopt 1bit, be i.e. " 1 " corresponding the first feedback system, " 0 " corresponding the second feedback system.According to the quantity of feedback system, the bit number that the first bit information takies also can change, and such as four feedback systems are arranged, can adopt 2bit.Can also the corresponding relation of feedback system and the first bit information be upgraded as required.
In enforcement, need to guarantee to adopt between network equipment 10 and terminal 20 identical feedback system and the corresponding relation of the first bit information.Such as can be definite by consulting between network equipment 10 and terminal 20, can also stipulate in agreement.
The implicit expression notice:
The principle of implicit expression notice is to adopt other configuration information (not being namely the information that is specifically designed to the configuration feedback system), such as the configuration information at present LTE and LTE-A and after the configuration information that needs to increase be the more implications of these configuration informations increases, do not need to tell separately which kind of feedback system is terminal 20 adopt, and comparing explicit notification can saving resource.The below is elaborated.
Mode one, maximum number bits corresponding to notification terminal 20 feedback systems, the wherein maximum number bits that takies of maximum number bits corresponding to the feedback system feedback information that to be terminal send according to this feedback system.Due to different feedback systems, bit number that can feedack is not identical, so only need to inform that terminal 20 sends the maximum number bits that feedback informations take, terminal 20 is just known and adopted which kind of feedback system.
Concrete, network equipment 10 determines that according to the feedback system that sets in advance and the corresponding relation of maximum number bits needing the maximum number bits corresponding to feedback system of configuration is configuration information; Accordingly, terminal 20 determines according to the feedback system that sets in advance and the corresponding relation of maximum number bits the feedback system that maximum number bits is corresponding.
The mode of employing implicit notification terminal 20 maximum number bits has a variety of, such as passing through to be mode implicit expression notification terminal 20 maximum number bits of the descending polymerization number of carriers of terminal configuration.
The below is based on the PUCCH feedback system of DFT-S-OFDM and PUCCHformat 1b with channel selection feedback system take feedback system and describes as example.
For FDD (Frequency division duplex, Frequency Division Duplexing (FDD)) system, in the corresponding relation of feedback system and maximum number bits, maximum number bits corresponding to PUCCH Format 1b with channel selection feedback system can be any one in 1～4, can be also that a scope is such as being not more than 4; Can be any one numerical value greater than 5 based on maximum number bits corresponding to the PUCCH feedback system of DFT-S-OFDM, can be also a scope such as greater than 4.
In the FDD system, if need terminal 20 to use PUCCH Format 1b with channelselection feedback system, determine that maximum number bits is not more than 4, namely the polymerization descending carrier quantity of configuration is not more than 4.That is to say, when the polymerization descending carrier quantity of configuration is not more than 4, use PUCCHFormat 1b with channel selection feedback system; Otherwise, use the PUCCH feedback system based on DFT-S-OFDM.Accordingly, terminal 20 as maximum number bits, is then just known polymerization descending carrier quantity according to the corresponding relation of feedback system and maximum number bits and is adopted which kind of feedback system.
Such as the polymerization descending carrier quantity that configures is 3, if in the corresponding relation of feedback system and maximum number bits, maximum number bits is a scope, terminal 20 is checked the feedback system corresponding to scope of the maximum number bits under in the of 3, because scope corresponding to PUCCH Format 1b with channel selection feedback system is to be not more than 4, so determine to adopt PUCCH Format 1b with channel selection feedback side;
If in the corresponding relation of feedback system and maximum number bits, maximum number bits is a value, directly determine the feedback system of 3 correspondences.
TDD (Time division duplex, time division duplex) system and FDD system class seemingly, difference is due to the TDD system, multiple uplink-downlink configuration is arranged, so for every kind of uplink-downlink configuration, maximum number bits can be had any different.Because maximal bit is different, not identical for the corresponding relation of the feedback system of every kind of uplink-downlink configuration and maximum number bits yet.
Concrete, if need terminal 20 to use PUCCH Format 1b with channel selection feedback systems, determine maximum number bits otherwise greater than N
1, namely the polymerization descending carrier quantity of configuration is not more than N
1That is to say, when the descending carrier number of polymerization is not more than N
1The time, terminal 20 is used PUCCH Format1b with channel selection; Otherwise, the PUCCH that terminal 20 is used based on DFT-S-OFDM, wherein N

In enforcement, need to guarantee to adopt between network equipment 10 and terminal 20 identical feedback system and the corresponding relation of maximum number bits.Such as can be definite by consulting between network equipment 10 and terminal 20, can also stipulate in agreement.
Mode two, PUCCH resource information corresponding to notification terminal 20 feedback systems.Due to different feedback systems, need configuration also not identical to the PUCCH resource of terminal 20, so only need to inform the corresponding PUCCH resource information of terminal 20 feedback systems, terminal 20 is just known which kind of feedback system of employing.
Concrete, network equipment 10 determines that according to the feedback system that sets in advance and the corresponding relation of PUCCH resource information needing the PUCCH resource information corresponding to feedback system of configuration is configuration information; Accordingly, terminal 20 determines according to the feedback system that sets in advance and the corresponding relation of PUCCH resource information the feedback system that the PUCCH resource information is corresponding.

For the PUCCH feedback system based on DFT-S-OFDM, network side only needs semi-static configuration to get final product to 201 PUCCH channel resources of terminal.So the PUCCH channel resource quantity corresponding based on PUCCH resource information corresponding to the PUCCH of DFT-S-OFDM is X.That is to say, when terminal 20 is determined PUCCH channel resource quantity=X according to the PUCCH resource information, just know the PUCCH feedback system that needs to adopt based on DFT-S-OFDM.Accordingly, when terminal 20 was determined PUCCH channel resource quantity＞X according to the PUCCH resource information, just knowing needed to adopt PUCCH format 1b withchannel selection feedback system.
Such as X is 1 o'clock, terminal 20 is determined PUCCH channel resource quantity=1 o'clock according to the PUCCH resource information, just adopts the PUCCH feedback system based on DFT-S-OFDM; Terminal 20 is determined PUCCH channel resource quantity＞1 o'clock just to adopt PUCCH format 1b withchannel selection feedback system according to the PUCCH resource information.Accordingly, in the corresponding relation of feedback system and PUCCH resource information, the PUCCH channel resource quantity of determining based on PUCCH resource information corresponding to the PUCCH feedback system of DFT-S-OFDM is that the definite PUCCH channel resource quantity of PUCCH resource information corresponding to 1, PUCCH format 1b with channel selection feedback system is greater than 1.
The PUCCH channel resource quantity determined of PUCCH resource information corresponding to PUCCH format 1b with channel selection feedback system can not be a scope but greater than the one or more numerical value in 1 concrete numerical value (be same feedback system can corresponding a plurality of PUCCH resource informations) as required.
Such as PUCCH channel resource quantity is 2, if the PUCCH channel resource quantity that in the corresponding relation of feedback system and PUCCH resource information, the PUCCH resource information is determined is a scope, terminal 20 is checked the feedback system corresponding to scope of the PUCCH channel resource quantity under in the of 2, because scope corresponding to PUCCHFormat 1b with channel selection feedback system is greater than 1, so determine to adopt PUCCH Format 1b with channel selection feedback system;
If the PUCCH channel resource quantity that in the corresponding relation of feedback system and PUCCH resource information, the PUCCH resource information is determined is a value, directly determine the feedback system of 2 correspondences.
If concrete numerical value, in FDD system and TDD system, determine that concrete numerical value is slightly different.
When the needs terminal is used PUCCH Format 1b with channel selection feedback system, network equipment 10 needs semi-static configuration to terminal 20M PUCCH channel resource (just can determine the PUCCH resource information according to these PUCCH channel resources, thereby set up corresponding relation).
For the FDD system, the polymerization descending carrier quantity that M need to configure, and M can not equal 1; For the TDD system, not identical for the size of every kind of uplink-downlink configuration M due to multiple uplink-downlink configuration being arranged yet, but need to guarantee that M, specifically can be referring to table 4 greater than 1.N wherein
