Description

The sending method of control information and device

Technical field

The present invention relates to field of mobile wireless communication, in particular to a kind of sending method controlling information and device.

Background technology

In mobile communication system, due to the feature of wireless fading channel time-varying so that communication process exists substantial amounts of the most true Qualitative, on the one hand in order to improve throughput of system, use the high order modulation that transfer rate is higher to carry out with few redundant correcting code Communication, so when wireless fading channel signal to noise ratio is more satisfactory, throughput of system is greatly improved really, but works as Then cannot ensure when channel is in deep fade that reliable communications is stably carried out, on the other hand, in order to ensure the reliability of communication, Low-order-modulated and big redundant correcting code that employing transfer rate is relatively low communicate, and i.e. protect when wireless channel is in deep fade The carrying out that barrier reliable communications is stable, but when channel SNRs is higher, owing to transfer rate is relatively low, the system of constraining gulps down The raising of the amount of telling, thus cause the waste of resource, in the development early stage of mobile communication technology, people resist wireless fading channel The time-varying characteristics of channel, can only use the transmitting power strengthening transmitter, use the modulation coding method of the big redundancy of low order Carry out the safeguards system communication quality when channel deep fade, also have no time to think it over and how to improve the handling capacity of system.But, with The progress of technical merit, occur in that can be adaptively adjusted it according to channel status launches power, modulation coding mode And the frame length of data overcomes the time-varying characteristics of channel thus obtains the technology of optimal communication effect, it is referred to as self adaptation and compiles Code modulation technique, belongs to most typical link adaptation techniques.

In Long Term Evolution (Long Term Evolution is called for short LTE) system, for realizing descending adaptive coding Modulation technique, the transmission of up needs includes that channel condition information (Channel State Information is called for short CSI) exists Interior control signaling.CSI includes channel quality instruction (Channel Quality Indicator is called for short CQI), precoding Matrix instruction (Pre-coding Matrix Indicator is called for short PMI) and order instruction (Rank Indicator is called for short RI). CSI reflects down physical channel state.Base station utilizes CSI to carry out descending scheduling, carries out the coded modulation of data.

CQI is used to weigh an index of down channel quality quality.In 36-213 agreement, CQI is with 0～15 Integer value represents that different CQI grades, different CQI correspond to respective Modulation and Coding Scheme (Modulation respectively And Coding Scheme, is called for short MCS), it is shown in Table 1.

Table 1 CQI table

In table 1, QAM (Quadrature Amplitude Modulation) represents quadrature amplitude modulation, QPSK (Quadrature Phase Shift Keying) represents QPSK, belongs to digital modulation mode.

The definition of CQI: the selection of CQI grade should follow following criterion: unrestricted based in frequency domain and time domain Assay intervals, corresponding each CQI value reported at sub-frame of uplink n, subscriber equipment (User Equipment is called for short UE) Index obtaining an index range meeting following condition at the maximum CQI of 1-15；If CQI index is 1 all Condition is not satisfied, then CQI index is 0.This condition (that is to say that CQI calculates the hypothesis of institute's foundation) is: single Physical Downlink Shared Channel (Physical Downlink Shared Channel, be called for short PDSCH) transmission block connect Time receiving error rate is less than 0.1.This PDSCH transmission block takies one group of downlink physical Resource Block (Physical Resource Block, is called for short PRB), i.e. CSI reference resources；The modulation system of described PDSCH transmission block and transport block size with CQI grade is corresponding.Wherein, this maximum CQI index is to ensure that Block Error Rate (Block Error Ratio is called for short BLER) It is not more than the maximum CQI index of 0.1, is conducive to controlling resource distribution.In general, CQI value is the least, corresponding MCS BLER performance the best.

Constantly promoting of communication technology demand proposes new technology requirement to communication system.Terminal may be adjusted by CQI instruction Other parameters beyond coded system processed, help system is better achieved Adaptive Transmission, promotes throughput of system.It addition, Following 5G communication system applications scene is enriched, and miscellaneous service demand and transmission are assumed also different.Such as in some scene In require that data transmission delay is less, reliability is higher；Corresponding, evolution or new communication system requirements data The physical time-frequency resource taken is different from existing system: such as one transmission block may only occupy less than 1ms subframe, and/ Or the running time-frequency resource less than 1 PRB.Super transmitting is required, it is desirable to the transmission BLER of data in some scene Less.

Detailed description of the invention

Below with reference to accompanying drawing and describe the present invention in detail in conjunction with the embodiments.It should be noted that in the feelings do not conflicted Under condition, the embodiment in the application and the feature in embodiment can be mutually combined.

It should be noted that term " first " in description and claims of this specification and above-mentioned accompanying drawing, " second " Etc. being for distinguishing similar object, without being used for describing specific order or precedence.

Before describing the embodiment of the present invention in detail, first as follows to some technical interpretations related in the present embodiment: constellation It is a kind of technology relevant to high order modulation that figure resets (Constellation Re-arrangement, referred to as CoRe). In order to obtain the higher availability of frequency spectrum, in numerous communication standard protocols, increasingly tend to use high-order modulating Improving system spectrum utilization rate and hardware circuit solution performance, wherein, the most commonly used high order modulation approach includes 16QAM, 64QAM etc..In these high order modulation approach, constellation point bit often has different reliabilities Grade, say, that in same modulation symbol, two bits therein will have higher than two other bit Bit error probability.Therefore, the reliability how utilizing constellation point different mappings bit improves decoding and transmission performance is current The problem needing to solve.Constellation Rearrangement technology is by the bit mapping ruler in reindexing, in continuous print mixing automatically Repeat requests (Hybrid Automatic Repeat Request, referred to as HARQ) attached bag retransmission processes equalizes each code The spectrum energy of word bit, thus the reliability of average code word bits, strengthen the performance of link, improve system reliability.
