Description

A kind of sending method of feedback information and terminal
Technical field
The present invention relates to the communications field, relate in particular to the sending method and the terminal of a kind of feedback information that has adopted carrier aggregation technology.
Background technology
Mixing in automatic request retransmission (HARQ, the Hybrid Automatic Repeat Request) mode, the code word of making a start and sending 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, if in the error correcting capability of code word; Then carry out error correction automatically; If wrong a lot, surpassed the error correcting capability of code word, but can faults come out; Then receiving terminal is given the decision signal of making a start through feedback channel, requires to make a start retransmission of information.In OFDM (OFDM, Orthogonal Frequency Division Multiplex) system, feed back to the base station through HARQ-ACK (HARQ Acknowledgement:HARQ response message); Need to judge whether to retransmit with this; When the HARQ-ACK response message that feeds back to the base station was ACK, the expression receiving terminal correctly received, and when the HARQ-ACK response message that feeds back to the base station is NACK; The expression receiving terminal receives mistake, needs the base station to retransmit.
At Long Term Evolution (LTE; Long Term Evolution; Its pairing standard agreement is Rel-8/9) in the system; The HARQ-ACK response message can go up separately at Physical Uplink Control Channel (PUCCH:Physical Uplink Control Channel) and send, and also can go up at Physical Uplink Shared Channel (PUSCH:Physical Uplink Shared Channel) and send with data.
At time division duplex (TDD; Time Division Duplex) in the system; Because ascending-descending subframes is not one to one; The ACK/NACK response message that is to say a plurality of descending sub frames correspondences need be sent on the PUCCH/PUSCH of sub-frame of uplink channel, and binding window (bundling window) has been formed in the descending sub frame set that wherein sub-frame of uplink is corresponding.
In LTE TDD; Defined two kinds of HARQ-ACK feedback models: a kind of HARQ-ACK of being binds (HARQ-ACK bundling); The basic thought of this feedback model be need be at each descending sub frame of this sub-frame of uplink feedback the HARQ-ACK message of corresponding streams of code words carry out logic and operation; If when the PDSCH of descending sub frame emission comprises 2 streams of code words, shown in Fig. 1 a, UE (subscriber equipment; Or claim the terminal) to feed back the HARQ-ACK response message corresponding to 2 bits of each streams of code words of having passed through the operation of subframe logical AND; If the PDSCH of each sub-frame emission all has only a streams of code words, shown in Fig. 1 b, UE will feed back the HARQ-ACK response message corresponding to 1 bit of this streams of code words of having passed through the operation of subframe logical AND; When UE when current subframe does not have PUSCH to send, UE will adopt form 1a/1b to send the HARQ-ACK response message of this 1/2 bit on PUCCH; And when UE when current subframe has PUSCH to send, then UE, sends this 1/2 bit information then through certain chnnel coding, channel interleaving and data multiplex together on PUSCH.
Another kind is HARQ-ACK multiplexing (HARQ-ACK multiplexing) feedback model; As shown in Figure 2; This feedback model need be HARQ-ACK response message of each descending sub frame feedback, and a plurality of subframes then need be fed back a plurality of HARQ-ACK response messages, and when the PDSCH of certain descending sub frame emission comprises 2 streams of code words; Earlier the HARQ-ACK response message of each streams of code words is carried out the logical AND operation, finally the only corresponding HARQ-ACK response message of each descending sub frame.When UE when current subframe does not have PUSCH to send; UE will adopt PUCCH form 1b combined channel to select the feedback system of (format 1b with channel selection) (selecting feedback system hereinafter to be referred as channel) to send this a plurality of HARQ-ACK response messages on PUCCH, and the core concept of this method is exactly to utilize on different PUCCH channels and this channel different modulation symbols to represent different HARQ-ACK response messages.This method makes portable HARQ-ACK response message can reach 4 bits at most through the mode of channel selection combination control channel form 1b.
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 Evolution Advanced as the evolution standard of LTE; Abbreviate LTE-A as, its corresponding standard agreement is Rel-10) system need support bigger system bandwidth (reaching as high as 100MHz), and need backward compatibility LTE prior standard.On the basis of prior LTE system; Can the bandwidth of LTE system 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.
In the system that has introduced carrier aggregation, the carrier wave that carries out polymerization is called component carrier (Component Carrier abbreviates CC as), is also referred to as a Serving cell (Serving Cell).Simultaneously; Principal component carrier wave/sub-district (Primary Component Carrier/Cell has also been proposed; Abbreviate PCC/PCell as) and the notion of auxilliary component carrier/sub-district (Secondary Component Carrier/Cell abbreviates SCC/SCell as), in the system that has carried out carrier aggregation; At least comprise a main Serving cell and auxilliary Serving cell, wherein main Serving cell is in state of activation always.
When LTE-A had adopted carrier aggregation technology, when the base station is UE when having disposed a plurality of descending Serving cell, UE need feed back the HARQ-ACK response message of these a plurality of descending Serving cell corresponding codewords streams.In LTE-A, when the HARQ-ACK response message is sent, defined two kinds of feedback systems on Physical Uplink Control Channel: channel is selected feedback system and based on the feedback system of DFT-s-OFDM.Because all different with PUCCH format 1/1a/1b/2/2a/2b based on its channel architecture of feedback system of DFT-s-OFDM, thereby in existing LTE-A agreement, this structure is called as PUCCH form 3 (PUCCH format 3), and is as shown in Figure 3.The Physical Uplink Control Channel maximum of existing PUCCH form 3 structures can be supported the transmission of 20 bits.Though when feedback information is less than 20 bits; PUCCH form 3 can carry feedback information fully, but to the follow-up evolution technology of LTE-A, will support more carrier aggregation; Especially concerning the TDD system, the feedback information bits number of carrying will be far longer than 20 bits.Will cause certain bindings to reduce feedback quantity like this, reduce throughput of system.
