Description

The sending method of response message and device

Technical field

The present invention relates to digital communicating field, in particular to a kind of sending method and device of response message.

Background technology

The develop rapidly of digital communication system is had higher requirement to reliability of data communication, yet under abominable channel, especially in high data rate or the high-speed mobile environment, multipath interference and Doppler frequency shift etc. seriously affect systematic function.Therefore, effective error-control technique, (Hybrid Automatic Repeat Request, HARQ) technology just becomes the focus that the communications field endeavours to study especially to mix automatic request retransmission.

In the HARQ mode, the sign indicating number that sends of making a start not only can error detection, but also has certain error correcting capability.After the receiving terminal decoder is received code word, at first check error situation,, then carry out error correction automatically if in the error correcting capability of sign indicating number; If mistake is a lot, surpassed the error correcting capability of sign indicating number, come out but can detect mistake, then receiving terminal is given the decision signal of making a start by feedback channel, requires to make a start retransmission of information.In ofdm system, the correct or mistake of representing to transmit by correct response message/error response message (ACK/NACK:Acknowledgement/Negative Acknowledgement), and need to judge whether to retransmit with this.

At present, in the descending HARQ of long evolving system (LTE:Long Term Evolution), the ACK/NACK response message of Physical Downlink Shared Channel (PDSCH:Physical Downlink Shared Channel), when subscriber equipment (UE:User Equipment) when current subframe does not have Physical Uplink Shared Channel (PUSCH:Physical Uplink Shared Channel), be to go control channel (PUCCH:Physical Uplink Control Channel) physically to go up and send.As shown in Figure 1, a Physical Uplink Control Channel is on frequency domain, account for a Resource Block (Resource Block accounts for 12 subcarriers), on the time domain, continue two time slots, a subframe (1ms) just, the difference of the Cyclic Prefix that uses according to current subframe, the symbolic number that comprises is different.In addition, control channel carries out frequency hopping on two time slots, to obtain the frequency diversity gain.The Physical Uplink Control Channel of each UE in the sub-district (User Equipment) is by code division multiplexing.Because UE number that can be multiplexing on Resource Block is limited, when the UE that needs to send simultaneously Physical Uplink Control Channel in the sub-district surpasses the multiplexing number of users of Resource Block institute energy, can open up a Resource Block again, just the mode by sign indicating number branch+frequency division realizes Physical Uplink Control Channel multiplexing of each UE in the sub-district.

What the present invention is directed to is the problem of determining and sending of the channel resource of ACK/NACK, and therefore for the ease of understanding, concise and to the point introduction earlier here is used for the PUCCH format 1a/1b of loading ACK/NACK.

In the LTE frequency division duplex system (FDD), because ascending-descending subframes is one to one, so when PDSCH only comprised a transmission block, UE will feed back the ACK/NACK response message of 1 bit, when PDSCH comprised two transmission blocks, UE will feed back the ACK/NACK response message of 2 bits.So in LTE FDD system, as shown in Figure 2, the ACK/NACK response message, through BPSK/QPSK modulation (corresponding respectively to format 1a/1b), form a modulation symbol, it is 12 spread spectrum (frequency expansion sequence is 12 long CAZAC sequences) that modulation symbol earlier carries out spreading factor at frequency domain, again time domain through one long be the time domain expansion of 4 Walsh sign indicating number, the information symbol that is mapped to control channel form 1 correspondence as shown in Figure 2 then gets on, and forms a time slot with reference signal at last and will send signal.

And in time division duplex (TDD) system of LTE, because ascending-descending subframes no longer is one to one, according to different ascending-descending subframes configurations, a sub-frame of uplink sometimes needs to feed back the ACK/NACK response message of a plurality of descending sub frames, and a plurality of descending sub frames with a sub-frame of uplink correspondence are called a binding window (bundling window) here.In LTE, defined two kinds of ACK/NACK feedback models: a kind of is binding pattern (bundling), the core concept of this method is carrying out logic and operation in the ACK/NACK response message of the transmission block of each descending sub frame correspondence of this sub-frame of uplink feedback, if a descending sub frame has 2 streams of code words, UE will feed back the ACK/NACK response message of 2 bits, if each subframe has only a word stream, UE will feed back the ACK/NACK response message of 1 bit, and the ACK/NACK response message after the binding adopts PUCCH format 1a or 1b to send; Another kind is multiplexer mode (multiplexing, multiplexing with channel selection just, being also referred to as channel selects), the core concept of this pattern be utilize different modulation symbol on different PUCCH channels and this channel to represent need be at the different feedback states of the descending sub frame of this sub-frame of uplink feedback, if a plurality of word streams are arranged on the descending sub frame, elder generation carries out the ACK/NACK of a plurality of words stream feedbacks of descending sub frame to carry out the channel selection again after spatial logic and (also being called spatial bundling) so, uses PUCCH format 1b transmission then.That is to say that the 2 bit information b (0) and the b (1) that are carried by PUCCH format1b, and the index of PUCCH channel have represented to carry out the ACK/NACK response message after spatial logic and the operation.

In the LTE system, UE has dual mode to be identified for the channel resource index of the PUCCH of loading ACK/NACK response message A kind of is to obtain by high-level signaling, another kind be by with PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) the implicit mapping relations of first index of the CCE at place (Control Channel Element, control channel unit) obtain.Like this, in a up-link carrier, the zone of ACK/NACK channel resource just is divided into two zones, and one is the zone by the high-level signaling configuration, and one is the implicit dynamic area of shining upon of index according to the CCE of PDCCH.In a single day UE has obtained the channel resource index of PUCCH

After, according to the channelizing formula of agreement regulation, the Resource Block index at place in fact in the time of just calculating UE transmission ACK/NACK, the cyclic shift amount of the index of the time domain orthogonal sign indicating number of use and corresponding C AZAC sequence.

At senior international mobile communication (Intemational Mobile Telecommunications-Advanced, abbreviate IMT-Advanced as) in the system, can realize the high-speed transfer of data, and has a bigger power system capacity, under the situation about move at low speed, focus covering, the peak rate of IMT-Advanced system can reach 1Gbit/s, and under the situation that high-speed mobile, wide area cover, the peak rate of IMT-Advanced system can reach 100Mbit/s.

In order to satisfy (the International Telecommunication Union-Advanced of senior International Telecommunications Union, abbreviate ITU-Advanced as) requirement, senior Long Term Evolution (Long Term EvolutionAdvanced as the evolution standard of LTE, abbreviating LTE-A as) system need support bigger system bandwidth (reaching as high as 100MHz), and need the existing standard of backward compatibility LTE.On the basis of prior LTE system, the bandwidth of LTE system can be merged and obtain bigger bandwidth, this technology is called carrier aggregation (Carrier Aggregation, abbreviate CA as) technology, the availability of frequency spectrum, alleviation frequency spectrum resource that this technology can improve the IMT-Advance system are in short supply, and then optimize the utilization of frequency spectrum resource.

After introducing carrier aggregation, in the current discussion about downlink component carrier and PDSCH transmission block and HARQ process relation, a groundwork supposition is when not adopting space division multiplexing, a corresponding PDSCH transmission block of downlink component carrier and a HARQ process, that is to say that UE need feed back the ACK/NACK response message of 1 bit for a PDSCH transmission block of each component carrier.And when adopting space division multiplexing, the current regulation of LTE-A is supported 2 transmission blocks at most.Therefore, when adopting space division multiplexing, UE need feed back the ACK/NACK response message of 2 bits for 2 PDSCH transmission blocks of each downlink component carrier.

In the LTE-AFDD system after having adopted the spectrum aggregating technology, upstream bandwidth and downlink bandwidth just can comprise a plurality of component carriers.When the base station all has scheduling to give the PDSCH of certain UE on a plurality of downlink component carriers, and when UE when current subframe does not have PUSCH to send, subscriber equipment need feed back the ACK/NACK response message of the PDSCH transmission of these a plurality of downlink component carriers on the PUCCH of the UL of UE special use PCC/Pcell.And in the TDD system, because the asymmetry of ascending-descending subframes configuration, a sub-frame of uplink need feed back the ACK/NACK response message of the PDSCH of a plurality of descending sub frames, and therefore, subscriber equipment need feed back the more ACK/NACK response message of heavy load.

For the ACK/NACK response message, except using PUCCH format 1a and the 1b that in LTE, has defined, channel is selected outside (multiplexing with channel selection), LTE-A has increased a kind of new form based on DFT-s-OFDM, be used to send the more ACK/NACK response message of heavy load, its channel architecture schematic diagram for convenience of description, is called PUCCH Format 3 (PUCCH form 3) with this structure as shown in Figure 3.Wherein which kind of mode UE adopts come feeding back ACK/NACK to be disposed by high level.

In LTE-A FDD system, about the feedback of ACK/NACK, define two kinds of patterns: a kind of is channel selection modes, and this pattern can be supported the ACK/NACK feedback of maximum 4 bits; Another kind is the DFT-s-OFDM pattern, and this pattern can be supported the ACK/NACK feedback greater than 4 bits;

Wherein, which kind of mode UE adopts come feeding back ACK/NACK to be disposed by high level, and regulation, when UE is configured to adopt the DFT-s-OFDM pattern, if UE receives only main downlink component carrier/sub-district (DL PCC/Pcell) in current subframe, then UE will adopt PUCCH format 1a/1b resource to come feeding back ACK/NACK response message.

And in the LTE-ATDD system, the feedback of ACK/NACK, on the basis of FDD configuration mode, done further refinement:

When user device configuration when adopting PUCCH format 3 feeding back ACKs/NACK:

Mode?1：

Support the ACK/NACK feedback of 20 bits at most;

If the ACK/NACK bit number of feedback surpasses 20, then carry out space bindings (spatial bundling);

If the ACK/NACK bit number of feedback is no more than 20, need not to carry out any type of bindings (bundling);

Mode?2：

When the bit number of ACK/NACK surpassed x, on the basis of space binding, by the mode of component carrier binding (CC bundling) or time binding (time bundling), the ACK/NACK bit number that needs are fed back was limited within the x bit;

The concrete value of x is final not to be determined;

Whether need to support that mode 2 also needs further discussion.

When user device configuration is selected feeding back ACK/NACK for adopting channel:

Mode?a：

The ACK/NACK bit number of feedback is no more than 4, without any need for the binding of form.

Mode?b：

The ACK/NACK bit number that feeds back surpasses 4, and then on the basis of space binding, by the mode of component carrier binding (CC bundling) or time binding (time bundling), the ACK/NACK bit number that needs are fed back is limited within 4 bits;

Specifically be to adopt component carrier binding or the binding of employing time not to determine as yet at present;

About the resource allocation problem under the above-mentioned various ACK/NACK feedback models, current conclusion is:

In the FDD system when UE is configured to adopt DFT-s-OFDM feeding back ACK/NACK, use PUCCH format 3 resources by high-level signaling (RRC signaling) configuration+ARI (A/N Resource indicator, the A/N resource indicator) dynamically indication, ARI realizes by TPC (Transmit Power Control, the transmitting power control) territory of reusing DCI.

When UE is configured to adopt channel to select feeding back ACK/NACK, do not determine because the mapping table design during channel selective mode is also final, thereby how employed PUCCH format 1a/1b resource determines also there is not conclusion in the FDD system.In addition, adopt channel to select the UE of feedback for being configured to, if UE receives only main downlink component carrier/sub-district (DL PCC/Pcell) in current subframe, then how UE will feed back and also not provide solution.

And for the multiple ACK/NACK feedback system in the TDD system, how its corresponding resource determines still not have at present corresponding scheme.

In addition, in the TDD system, for the subscriber equipment that is configured to carrier aggregation, when subscriber equipment received only the transmission of main downlink component, how the ACK/NACK response message on its corresponding each subframe this fed back.

As the above analysis,, and under some situation, still do not have the concrete scheme of feeding back ACK/NACK at present, so that UE can't finish the transmission of ACK/NACK, and then influence the performance of network because UE is current the various configurations situation.

Summary of the invention

Main purpose of the present invention is to provide a kind of sending method and device of response message, to solve the problem that UE under above-mentioned some situation can't finish the transmission of ACK/NACK at least.
