Description
Technical field
The present invention relates to wireless communication technology field, more particularly, to PUCCH feedback information detecting method in a kind of LTE and
System.
Background technique
In LTE (Long Term Evolution, long evolving system) system, and LTE-A (LTE-Advanced, it is advanced
Long evolving system) be the evolution version of LTE, in order to meet LTE-A downlink peak speed 1Gbps, uplink peak speed 500Mbps's is wanted
It asks, it is desirable to provide the transmission bandwidth of maximum 100MHz, but it is rare due to the continuous frequency spectrum of so big bandwidth, LTE-A is proposed
Carrier wave polymerize the solution of (Carrier Aggregation, CA).So-called carrier wave polymerization, is by 2 or more carrier wave lists
First (Component Carrier, CC) condenses together to support the transmission bandwidth for being up to 100MHz.
In LTE-A agreement, because newly-increased carrier wave polymerizable functional introduces PUCCH1B CS format (PUCCH
Format1B with Channel Selection), it is used for transmission the ACK/NACK feedback to downlink.By using the format
UE can feed back the downlink reception result of different carrier waves.PUCCH1B CS is that the PUCCH1B format based on LTE R8/9 agreement spreads out
It is raw, although the only feedback information of carrying 2bit, but base station in each subframe by detecting PUCCH1BCS's
The content of resource location and carrying can confirm that UE in the downlink reception of each carrier wave according to the mapping form provided in agreement
As a result.PUCCH1B CS format could support up lower 2 code words of 2 carrier waves in the reception condition of multiple downlink subframes, terminal feedback
When reception result, there are two types of workable resource locations: one is the CCE indexes used by PDCCH, are provided using agreement
Formula, which calculates, to be obtained, that is, uses formulaCome
Calculate PUCCH resource position；Another kind is to configure to obtain by high-level signaling N1PUCCH-AN-CS-r10.The money in two kinds of sources
Source position, UE select corresponding resource location to be fed back according to reception condition, according to agreement.
Since in TDD UL-DL configuration 1~6, there are multiple D sub-frame transmissions to correspond to the same UE
The case where being fed back has formulated ACK/NACK bundling feedback model and ACK/NACK thus in LTE TDD
Multiplexing feedback model.In ACK/NACK bundling feedback model, the PDSCH transmission of M D subframe is (referred to as
One HARQ feedback window) terminal feed back in time and after operation, corresponding identical TB block in final M D subframe
The ACK/NACK information of 1bit is formed, if base station receives the NACK of corresponding TB, multiple D transmission of bunding transmission feedback
All carry out HARQ re-transmission.Above-mentioned is ideal transmission-feedback states.But in practice, PDCCH transmission is not 100% reliable, UE
Certain downlink DCI may be lost, so when certain downlink DCI in HARQ feedback window lose, the state of base station and terminal
There have been inconsistent, base station is thought to transmit certain D subframe, but terminal does not know the presence for having the downlink transfer, more talks
The judgement and feedback of ACK/NACK are carried out on not to it, it then may mistakenly feeding back ACK under bundling feedback model.
Therefore, the protection of the case where may losing in LTE-A agreement particular for PDCCH/PDSCH and tailor is arranged
Apply, both up and down in row authorization PDCCH in the DAI information that carries or PUSCH feedback information use based on Nbundled's
Scrambler sequence is provided to enhance the reliability of feedback, it is most important that guarantee base station and terminal are in transmission event statistics and instead
Consistency on feedforward information.
But the prior art there are still one may cause base station and the terminal inconsistent loophole in feedback and be:
1) if base station thinks that terminal has PUSCH transmission (to have the corresponding PUSCH transmission of PDCCH or nothing in feedback subframe
The corresponding PUSCH transmission of PDCCH), but terminal side is lost the authorization of the PUSCH transmission, it is not known that there is the PUSCH transmission thing
The presence of part, causes terminal still to be fed back using PUCCH, and base station is thought feed back on PUSCH, then base station parses
The resource that the resource and terminal of feedback information send feedback information is inconsistent.Lose terminal feedback information in base station.
2) if same base station thinks that terminal has the corresponding PUSCH transmission of PDCCH in feedback subframe, but terminal side is lost
The corresponding uplink PDCCH authorization of the PUSCH transmission, terminal side think that the subframe has another to pass without the corresponding PUSCH of PDCCH
It is defeated, then cause terminal to think be fed back on the corresponding PUSCH of no PDCCH, and base station thinks there be PDCCH pairs
Feedback reception is carried out on the PUSCH answered, then the resource of base station parsing feedback information and the resource of terminal transmission feedback information are different
It causes.Lose terminal feedback information in base station.
Above situation shows that agreement expectation ensures that base station and terminal in the consistency of downlink transfer and feedback, mention as far as possible
The accuracy of high terminal feedback, the possibility lost special consideration should be given to PDCCH authorization are influenced caused by feedback.Due to guarantee
The consistency of the corresponding uplink PUCCH feedback of PDSCH downlink transfer, so agreement takes many kinds of measures to ensure that terminal can be accurate
The loss situation for knowing downstream grants PDCCH or PDSCH transmission.But the uplink feedback of PDSCH downlink transfer is not just
It is carried out on PUCCH, it is possible to it is carried out on PUSCH, and it is uplink authorization PDCCH that PUSCH is corresponding, if uplink authorization
PDCCH itself is lost, and it is inconsistent in feedback that will cause new base station and terminal naturally.Agreement has ignored just herein
Uplink authorization PDCCH influences caused by losing the feedback downlink transfer PDSCH.
