Description
Technical field
The present invention relates to moving communicating field, particularly relate to a kind of high-order code processing method, device and system.
Background technology
In mobile communication system, become due to during wireless fading channel, make communication process there is a large amount of uncertainties.On the one hand in order to improve throughput of system, the higher high order modulation of transmission rate is adopted to communicate with few redundant correcting code, when wireless fading channel signal to noise ratio is more satisfactory, throughput of system is greatly improved really like this, but then cannot ensure that when channel is in deep fade reliable communications is stably carried out, on the other hand, in order to ensure the reliability of communication, the lower low-order-modulated of transmission rate is adopted to communicate with large redundant correcting code, namely the carrying out that reliable communications is stable is ensured when wireless channel is in deep fade, but when channel SNRs is higher, because transmission rate is lower, constrain the raising of throughput of system, thus cause the waste of resource.Early stage in the development of mobile communication technology, people resist the time-varying characteristics of wireless fading channel, the transmitting power strengthening transmitter can only be adopted, use the modulation coding method of the large redundancy of low order to carry out the communication quality of safeguards system when channel deep fade, also have no time to think it over and how to improve the throughput of system.Along with the progress of technical merit, occur can regulating its transmitting power adaptively according to channel status, the frame length of modulation coding mode and data overcomes the time-varying characteristics of channel thus the technology of acquisition optimal communication effect, be called as adaptive coding modulation, belong to most typical link adaptation techniques.
In Long Term Evolution (LTE:Long Term Evolution) system, for realizing adaptive coding modulation, up needs transmission comprises the control signal of channel condition information (CSI:Channel State Information).CSI comprises channel quality instruction (CQI:Channel quality indication), pre-coding matrix instruction (PMI:Pre-coding Matrix Indicator) and order instruction (RI:RankIndicator).CSI reflects down physical channel state.Base station utilizes CSI to carry out descending scheduling, carries out the coded modulation of data.The feedback of CSI can be periodic, also can be acyclic.
CQI is used to the index weighing down channel quality quality.In 36-213 agreement CQI with 0 ~ 15 integer value represent, represent different CQI grades respectively, different CQI correspond to respective Modulation and Coding Scheme (MCS:Modulation and Coding Scheme), in table 1.CQI grade selected by terminal (UE:User Equiment), should make the Physical Downlink Shared Channel corresponding to this CQI (PDSCH:Physical Downlink Shared Channel) transmission block (TB:Transport Block) Block Error Rate under corresponding MCS be no more than 0.1.
Table 1
QAM(Quadrature Amplitude Modulation in upper table 1) represent quadrature amplitude modulation, QPSK(Quadrature Phase Shift Keying) represent Quadrature Phase Shift Keying, be a kind of digital modulation mode.
In LTE, except differential CQI, CQI 4 bits represent.CQI bit is included in ascending control information (UCI:Uplink Control Information) and reports.Base station is dispatched in conjunction with the CQI of terminal to report, and determines descending MCS index and resource allocation information.Specifically, the LTE protocol of Rel-8 defines a modulation and transmission block size form (Modulation and TBS indextable, hereinafter also referred to MCS Table, MCS table).Form has 32 grades, substantially the corresponding MCS index of each grade, and each MCS index corresponding a kind of MCS(or a kind of spectrum efficiency in essence, notice that this MCS is not limited to the MCS of table 1).And resource allocation information gives the Physical Resource Block number NPRB that downlink transfer needs to take.LTE standard additionally provides a TBS form.According to described form, after given MCS index and NPRB, transmission block size (TBS:Transport block size) just can be obtained.There is these Coded modulation parameters (MCS/NPRB/TBS) base station just can carry out the coded modulation of downlink data, carried out downlink transfer.
After terminal receives the data of downlink transfer, need to obtain the MCS index of downlink transfer and the TBS demodulating and decoding for data.Base station is by Physical Downlink Control Channel (PDCCH:Physical DownlinkControl Channel), Downlink Control Information is sent with specific Downlink Control Information (DCI:Downlink ControlInformation) form (DCI format), comprise the MCS index of 5 bits, and resource distribution location.Terminal obtains TBS according to TBS form after obtaining Downlink Control Information, and for demodulating and decoding.DCI format comprises following multiple: DCI format0, DCI format1, DCIformat1A, DCI format1B, DCI format1C, DCI format1D, DCI format2, DCI format2A, DCI format2B, DCI format2C, DCI format2D, DCI format3 and DCI format3A etc.
LTE system, after experienced by the several version of Rel-8/9/10/11, studies R12 technology again successively.In existing Rel-11 standard, the modulation coding mode of uplink and downlink the highest support 64QAM.Along with the development of heterogeneous network, small-cell (small cell) needs the system spectral efficiency of higher message transmission rate and Geng Gao, requires to introduce more high order modulation coded system, such as 256QAM.Existing standard cannot meet this demand.Such as, the conventional form of existing LTE standard, namely CQI table/MCS table/TBS shows the highest support modulation coding mode of 64QAM and the spectrum efficiency of about 5.5547 bits/s/Hz.
Show for LTE system above, conventional form (i.e. existing CQI table, MCS shows, and TBS shows) cannot support more high-order modulating.Introduce high-order modulating in existing communication system, after such as 256QAM, 1024QAM, need design to support the enhancing form of high-order modulating (new CQI table, MCS shows, and TBS shows).Have two kinds of designs: the enhancing table size comprising high-order modulating MCS grade that scheme one designs is equal with conventional table size, such as, for LTE system, new CQI table and MCS table are respectively 16 and 32 grades; The enhancing table size comprising high-order modulating MCS grade that scheme two designs is greater than conventional form, and such as, for LTE system, new CQI table and MCS table are respectively 32 and 64 grades.Form is larger, and the range of spectral efficiencies that can cover is larger, or obtains higher spectrum efficiency granularity; But the required bit number for representing this form is also more.In order to the pluses and minuses of simple declaration two schemes, below LTE system introduce new CQI table after 256QAM be designed to example.For scheme one, the range of spectral efficiencies that new CQI table covers and spectrum efficiency granularity (spectrum efficiency granularity is corresponding the precision of channel state feedback) are conflicts.That is, the reduction that large range of spectral efficiencies must cause spectrum efficiency granularity be covered; Maintain existing spectrum efficiency granularity must cause strengthening form and cannot cover the range of spectral efficiencies that minimal frequency efficiency in conventional form (table 1) and the highest spectrum efficiency of 256QAM limit.But scheme one does not affect CQI bit number, the load of UCI payload(ascending control information can not be caused) increase, the UCI demodulation performance decline problem that the increase of CQI bit may bring need not be considered.For scheme two, new CQI table/MCS shows the range of spectral efficiencies that the minimal frequency efficiency that can cover completely when not affecting spectrum efficiency granularity in existing form and the highest spectrum efficiency of 256QAM limit, but increase CQI bit number, need the problem considering that UCI payload increases and UCI demodulation performance declines.Similarly, also there is similar problem in the scheme of new MCS table.
The conventional form of current communication system cannot support more high-order modulating, does not also solve the configuration use problem that concrete high-order modulating strengthens form and conventional form.Therefore, current communication system cannot support more high-order modulating.Relatively good at channel condition, may to apply more high-order modulating scene, in such as small-cell (Small Cell) scene, limits the lifting of data transmission peak rate and system spectral efficiency.
