Description
Technical field
The present invention relates to the communications field, more particularly to employ a kind of sending method of feedback information of carrier aggregation technology
And terminal.
Background technology
In hybrid automatic request retransmits (HARQ, Hybrid Automatic Repeat Request) mode, originator hair
The code word sent, can not only error detection, but also with certain error correcting capability.Receiving terminal decoder is received after code word, is examined first
Error situation is tested, if within the error correcting capability of code word, it is automatic to carry out error correction, if mistake is a lot, exceed code word
Error correcting capability, but can detect that mistake comes out, then receiving terminal gives originator one decision signal of hair by feedback channel, it is desirable to originator weight
Photos and sending messages.In OFDM (OFDM, Orthogonal Frequency Division Multiplex) system, lead to
Cross HARQ-ACK (HARQ Acknowledgement：HARQ response messages) base station is fed back to, judge whether to need weight with this
Pass, when the HARQ-ACK response messages for feeding back to base station are ACK, represent that receiving terminal is properly received, and work as and feed back to base station
When HARQ-ACK response messages are NACK, represent that receiving terminal receives mistake, it is necessary to which base station is retransmitted.
In Long Term Evolution (LTE, Long Term Evolution, the standard agreement corresponding to it are Rel-8/9) system
In, HARQ-ACK response messages can physically row control channel (PUCCH：Physical Uplink Control
Channel individually sent on), can also physically row shared channel (PUSCH：Physical Uplink Shared
Channel sent on) together with data.
In time division duplex (TDD, Time Division Duplex) system, what it is due to ascending-descending subframes is not one a pair
Answer, that is to say, that the corresponding ACK/NACK response messages of multiple descending sub frames need the PUCCH/ in a sub-frame of uplink
Sent on PUSCH channels, the wherein corresponding descending sub frame set of sub-frame of uplink constitutes binding window (bundling
window)。
In LTE TDD, two kinds of HARQ-ACK feedback models are defined：One kind is HARQ-ACK bindings (HARQ-ACK
Bundling), the basic thought of the feedback model is will to need the corresponding code of each descending sub frame in sub-frame of uplink feedback
The HARQ-ACK message of word stream carries out logic and operation, if the PDSCH transmittings of a descending sub frame include 2 streams of code words,
As shown in Figure 1a, UE (user equipment, or terminal) to feed back have passed through subframe logical AND operation correspond to each streams of code words
2 bits HARQ-ACK response messages, if PDSCH transmittings all only one of which streams of code words of each subframe, as shown in Figure 1 b,
UE will feed back the HARQ-ACK response messages for 1 bit corresponding to the streams of code words that have passed through the operation of subframe logical AND, when UE exists
When present sub-frame does not have PUSCH to send, UE will send the HARQ-ACK of this 1/2 bit on PUCCH using form 1a/1b
Response message；And when UE has PUSCH transmissions in present sub-frame, then UE compiles this 1/2 bit information by certain channel
Then code, channel interleaving send together with data-reusing on PUSCH.
Another is HARQ-ACK multiplexing (HARQ-ACK multiplexing) feedback models, as shown in Fig. 2 the feedback
Pattern needs to feed back a HARQ-ACK response message for each descending sub frame, and multiple subframes then need to feed back multiple HARQ-ACK
Response message, and when the PDSCH transmittings of certain descending sub frame include 2 streams of code words, first should to the HARQ-ACK of each streams of code words
Answer message and carry out logical AND operation, final each descending sub frame only corresponds to a HARQ-ACK response message.When UE is in current son
When frame does not have PUSCH to send, UE will be on PUCCH using PUCCH format 1b combined channels selection (format 1b with
Channel selection) feedback system (hereinafter referred to as channel selection feedback mode) come send this multiple HARQ-ACK should
Message is answered, the core concept of this method is exactly to be represented using modulation symbol different on different PUCCH channels and the channel
Different HARQ-ACK response messages.This method makes to carry by way of Channel assignment combination control channel form 1b
HARQ-ACK response messages at most up to 4 bits.
In order to meet senior International Telecommunication Union (International Telecommunication Union-
Advanced, referred to as ITU-Advanced) requirement, be used as senior long term evolution (the Long Term of LTE evolution standard
Evolution Advanced, referred to as LTE-A, its corresponding standard agreement are Rel-10) system need to support bigger be
Regiment commander is wide (reaching as high as 100MHz), and needs the existing standards of backward compatibility LTE., can on the basis of existing LTE system
To be combined to the bandwidth of LTE system to obtain bigger bandwidth, this technology is referred to as carrier aggregation (Carrier
Aggregation, referred to as CA) technology, the technology can improve IMT-Advance systems the availability of frequency spectrum, alleviate frequency spectrum
Resource scarcity, and then optimize the utilization of frequency spectrum resource.
In the system of carrier aggregation is introduced, the carrier wave being polymerize is referred to as component carrier (Component
Carrier, referred to as CC), also referred to as one serving cell (Serving Cell).It is also proposed that principal component carrier wave/small
Area (Primary Component Carrier/Cell, referred to as PCC/PCell) and auxiliary component carrier/cell (Secondary
Component Carrier/Cell, referred to as SCC/SCell) concept, in the system for carrying out carrier aggregation, at least wrap
Containing a main serving cell and auxiliary serving cell, wherein main serving cell is constantly in state of activation.
When LTE-A employs carrier aggregation technology, when base station is that UE is configured with multiple downstream service cells, UE needs
Feed back the HARQ-ACK response messages of this multiple downstream service cell corresponding codewords stream.In LTE-A, when HARQ-ACK responses disappear
When breath is physically sent in row control channel, two kinds of feedback systems are defined：Channel selection feedback mode and based on DFT-
S-OFDM feedback system.Due to its channel architecture of the feedback system based on DFT-s-OFDM and PUCCH format 1/1a/
1b/2/2a/2b is different, thus in existing LTE-A agreements, this structure is referred to as (the PUCCH format of PUCCH format 3
3), as shown in Figure 3.The Physical Uplink Control Channel maximum of the existing structure of PUCCH format 3 can support the transmission of 20 bits.Although
When feedback information is less than 20 bit, PUCCH format 3 can carry feedback information completely, but to LTE-A follow-up evolution skill
Art, will support more carrier aggregations, especially for TDD system, and the feedback information bits number of carrying will be far longer than
20 bits.Certain bindings will so be caused to reduce feedback quantity, throughput of system is reduced.
