Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts Example, shall fall within the protection scope of the present invention.

Referring to Fig. 1, Fig. 1 be a kind of flow chart of transmission method provided in an embodiment of the present invention, as shown in Figure 1, include with Lower step:

Step 101, the modulating-coding strategy index that network side equipment is sent is received；

Transmission method provided in an embodiment of the present invention is applied to mobile communication terminal, for control transmitting uplink data Modulation coding scheme.

In the step, network side equipment can be according to channel quality indicator (CQI) (Channel Quality Indicator) It determines the modulating-coding strategy index that mobile communication terminal uplink is sent, and sends modulating-coding strategy index to mobile terminal, To indicate that mobile communication terminal carries out the modulation coding scheme of uplink.Wherein, the content which specifically includes can To be configured according to actual needs, for example, the modulation coding scheme of transmitting uplink data may include BPSK (Binary Phase Shift Keying, binary phase shift keying), QPSK (Quadrature Phase Shift Keying, four phase phases Move keying), 16QAM (Quadrature Amplitude Modulation, QAM), 64QAM and 256QAM etc..

Step 102, according to the mapping relations of modulating-coding strategy index and modulation coding scheme, the determining and network side The modulating-coding strategy that equipment is sent indexes corresponding first modulation coding scheme；The mapping relations are propped up with network side equipment The modulation coding scheme for the highest level held is corresponding；

It will be appreciated that since whether different mobile communication terminal can support the modulation coding scheme of highest level simultaneously It is inconsistent, and above-mentioned mapping relations are needed for all mobile communication terminals, therefore include owning in the mapping relations The modulation coding scheme that mobile communication terminal is supported, i.e. its modulation for corresponding to the highest level that mobile communication system is supported Coding mode.

After mobile communication terminal receives the modulating-coding strategy index of network side equipment transmission, it will according to above-mentioned mapping Relationship, which is searched, obtains corresponding first modulation coding scheme of modulating-coding strategy index that network side equipment is sent.Specifically, should Mapping relations can be stored in a manner of MCS table.

Step 103, when the mobile communication terminal does not support first modulation coding scheme, from the mapping relations The second modulation coding scheme that the mobile communication terminal is supported is selected in the modulation coding scheme of record；

Step 104, transmitting uplink data is carried out using second modulation coding scheme.

In above-mentioned steps, the CQI that is sent due to network side equipment generally according to mobile communication terminal, it will send the CQI The corresponding modulating-coding strategy index of the maximum modulation coding mode that can be supported under state, however the ability of mobile communication terminal It is different, it is understood that there may be to support the modulating-coding strategy to index corresponding modulation coding scheme, it is also possible to not support the modulating-coding Strategy indexes corresponding modulation coding scheme.Specifically, when mobile communication terminal determines that network side refers to according to above-mentioned mapping relations After the modulation coding scheme shown, it will determine whether mobile communication terminal supports the first modulating-coding according to the capability state of itself Mode.If mobile communication terminal does not support first modulation coding scheme, institute is not supported from what above-mentioned mapping relations recorded It states first the second modulation coding scheme of modulation coding scheme and carries out transmitting uplink data；If mobile communication terminal supports described first Modulation coding scheme then can carry out transmitting uplink data according to the first modulation coding scheme.

Two different waveforms: cyclic prefix orthogonal frequency division multiplexing multiple access CP-OFDM and direct computation of DFT are defined in NR The orthogonal frequency division multiplexing multiple access DFT-S-OFDM (the case where being mainly used for the power limited of uplink) of leaf transformation spread spectrum.And it is every The modulation system that kind waveform is supported respectively slightly has difference, as shown in following table one.

Table one

CP-OFDM	DFT-S-OFDM
			π/2-BPSK
QPSK	QPSK
		16QAM	16QAM
64QAM	64QAM
		256QAM	256QAM

It can be found that the corresponding modulation coding scheme set of different OFDM waveforms is not identical, therefore, it is necessary to for not Different mapping relations are arranged in same OFDM waveform.It is different due to carrying out data transmission used waveform, and waveform is corresponding Above-mentioned mapping relations are also different, therefore in the specific embodiment of the invention, the needs when mobile communication system defines different wave Mapping relations are determined first, further, referring to Fig. 2, include: in above-mentioned steps 102

Step 1021, mapping relations corresponding with the orthogonal frequency division multiplexing multiple access waveform that current transmission uses are selected；

Step 1022, according to the mapping relations of the modulating-coding strategy of selection index and modulation coding scheme, determining and institute The modulating-coding strategy for stating network side equipment transmission indexes corresponding first modulation coding scheme.

In the present embodiment, above-mentioned orthogonal frequency division multiplexing multiple access waveform include: cyclic prefix orthogonal frequency division multiplexing multiple access and from Dissipate the orthogonal frequency division multiplexing multiple access of Fourier transformation spread spectrum.Wherein, it is propped up in the MCS table of cyclic prefix orthogonal frequency division multiplexing multiple access The modulation coding scheme held includes: QPSK, 16QAM, 64QAM and 256QAM；The orthogonal frequency division multiplexing of discrete Fourier transform spread spectrum It include: BPSK, QPSK, 16QAM, 64QAM and 256QAM with the modulation coding scheme supported in the MCS table of multiple access.

QPSK modulation system is generally operational in low signal-to-noise ratio scene, by system interference randomized jitter and precision of channel estimation It influences, hardly results in accurate CQI feedback；In addition current scene handling capacity is not that Major Systems are concerned about target, corresponding MCS Table section is too fine without designing.Therefore Q=5bit precision can cover under the premise of influencing less on throughput performance { QPSK, 16QAM, 64QAM, 256QAM } all situations.

In comparison, the corresponding modulation coding scheme of orthogonal frequency division multiplexing multiple access of discrete Fourier transform spread spectrum is more One BPSK, and under the scene of the orthogonal frequency division multiplexing multiple access in discrete Fourier transform spread spectrum, due to tending to work small Area edge situation, middle low signal-to-noise ratio probability of occurrence is higher, therefore the probability that 256QAM is used is relatively low.For probability of occurrence Corresponding region is too fine without designing in less high order modulation 256QAM, MCS table, then original a part can be corresponded to The MCS index of 256QAM is allocated to BPSK.

It should illustrate, when the mobile communication terminal does not support first modulation coding scheme, select second to adjust The rule of coding mode processed can be configured according to actual needs, for example, in the present embodiment, in order to guarantee the handling capacity of system And transmission rate, the second modulation coding scheme can choose are as follows: in the modulation coding scheme of the mapping relations record, the shifting The highest modulation coding scheme of grade that mobile communication terminal is supported.

In the present embodiment, due to using the highest modulation coding scheme of mobile communication terminal as the second modulating-coding side Formula, so as to improve the transmission rate of uplink transmission data as far as possible.

For example, when the MCS Index for receiving network side equipment transmission is 22 corresponding to 256QAM, if mobile communication The highest modulating-coding that terminal is supported is 64QAM, then mobile communication terminal determines the first modulating-coding side according to mapping relations Formula is 256QAM, and mobile communication terminal will search the second modulation coding scheme from mapping relations record again at this time, at this In embodiment, which is 64QAM, and mobile communication terminal will be carried out with the modulation coding scheme of 64QAM Row transmission.If the highest modulating-coding that mobile communication terminal is supported is 256QAM, mobile communication terminal will be with the tune of 256QAM Coding mode processed carries out uplink.

Further, network side equipment can also be indexed instruction mobile communication equipment by modulating-coding strategy and transmit data Spectrum efficiency.Referring to Fig. 3, after above-mentioned steps 101, this method further include:

Step 105, according to the mapping relations of modulating-coding strategy index and spectrum efficiency, the determining and network side equipment The modulating-coding strategy of transmission indexes corresponding first object spectrum efficiency；

Above-mentioned steps 104 specifically:

Transmitting uplink data is carried out using second modulation coding scheme and the first object spectrum efficiency.

In the present embodiment, the mapping relations of modulating-coding strategy index and spectrum efficiency are also stored in MCS table, specifically , as shown in following table two, the mapping relations and modulation of modulating-coding strategy index and spectrum efficiency are stored in MCS table The mapping relations of coding strategy index and modulation coding scheme.

Table two

In the present embodiment, when the MCS Index for receiving network side equipment transmission is 22, if mobile communication terminal is propped up The highest modulation coding scheme held is 64QAM, then mobile communication terminal determines that the first modulation coding scheme is according to mapping relations 256QAM, mobile communication terminal will search the second modulation coding scheme from mapping relations record again at this time, in this implementation In example, which is 64QAM, and mobile communication terminal will carry out uplink biography with the modulation coding scheme of 64QAM It is defeated.

At this point, the determination of spectrum efficiency can be configured according to actual needs, for example, in the present embodiment, Ke Yicong The corresponding MCS Index of second modulation coding scheme selects the corresponding spectrum efficiency of a MCS Index as above-mentioned first mesh Spectrum efficiency is marked, it is, of course, understood that generally selecting corresponding in the second modulation coding scheme to improve transmission rate The highest spectrum efficiency of spectrum efficiency is as above-mentioned first object spectrum efficiency, such as can choose spectrum efficiency is 5.04 As above-mentioned first object spectrum efficiency.In addition, it should be noted that, when mobile communication terminal ability only supports highest 64QAM When, it is 5.04 from the maximum frequency deviation efficiency reached known to table two above, and practical 64QAM theory can reach 0.93*6=5.58, When the corresponding spectrum efficiency of CQI index that terminal reports >=5.58, then two MCS index=22 of table is selected, is selected at this time The second modulation coding scheme be 64QAM, and it is 5.58 that first object frequency efficiency, which can choose, that is, keeps selection spectrum efficiency MCS index it is constant so that mobile communication terminal with the modulation coding scheme of 64QAM and 5.58 spectrum efficiency carry out Uplink.

In the present embodiment, the modulation coding scheme that can be supported for different mobile communication terminal highest is different, Ke Yiding The different MCS table of justice, the modulation coding scheme that can also be supported according to all mobile communication terminal highests define maximum MCS table, Maximum MCS table is interpreted according to the modulation coding scheme that mobile communication terminal highest is supported, obtains mobile communication terminal pair The MCS table that should be supported.Such as the modulation coding scheme that mobile communication terminal highest is supported is 64QAM, it is above-mentioned when interpreting MCS table The corresponding modulation system of MCS Index=22 is 6 in table, and the map record that MCS Index is 23 to 27 is nothing, such as following table three It is shown.

Table three

Further, referring to Fig. 4, the present invention also provides a kind of transmission methods, as shown in figure 4, the transmission method includes:

Step 401, determine that modulating-coding strategy indexes；

Transmission method provided in an embodiment of the present invention is applied to network side equipment, for the tune to control downlink data transmission Coding mode processed.

In the step, network side equipment can be according to channel quality indicator (CQI) (Channel Quality Indicator) Determine that the modulating-coding strategy index that downlink transmission is carried out to mobile communication terminal, modulating-coding strategy index are used to indicate volume Code mode, wherein the content that the coding mode specifically includes can be configured according to actual needs, for example, downlink data passes Defeated modulation coding scheme may include that (Binary Phase Shift Keying, is that analog signal is converted into data to BPSK One of conversion regime of value), QPSK (Quadrature Phase Shift Keying, four phase shift keying), 16QAM (Quadrature Amplitude Modulation, QAM), 64QAM and 256QAM etc..

Step 402, determining to be compiled with the modulation according to the mapping relations of modulating-coding strategy index and modulation coding scheme Code strategy indexes corresponding first modulation coding scheme；The tune for the highest level that the mapping relations and network side equipment are supported Coding mode processed is corresponding；

Network side equipment is after determining modulating-coding strategy index, it will obtains modulation according to above-mentioned mapping relationship searching and compiles Code strategy indexes corresponding first modulation coding scheme.Specifically, the mapping relations can be stored in a manner of MCS table.

Step 403, when the mobile communication terminal does not support first modulation coding scheme, from the mapping relations The second modulation coding scheme that the mobile communication terminal is supported is selected in the modulation coding scheme of record；

Step 404, downlink data transmission is carried out using second modulation coding scheme.

In the step, the ability of mobile communication terminal is different, it is understood that there may be supports modulating-coding strategy index corresponding Modulation coding scheme, it is also possible to the modulating-coding strategy not supported to index corresponding modulation coding scheme.Specifically, working as network side After equipment determines the modulation coding scheme of network side instruction according to above-mentioned mapping relations, it will determine whether mobile communication terminal props up Hold the first modulation coding scheme.If mobile communication terminal does not support first modulation coding scheme, from above-mentioned mapping relations Record does not support second modulation coding scheme of the first modulation coding scheme to carry out downlink data transmission；If mobile communication is whole First modulation coding scheme is supported at end, then can carry out downlink data transmission according to the second modulation coding scheme.Specifically, net Network side apparatus knows that the mode for the modulation coding scheme that mobile communication terminal highest is supported can be configured according to actual needs, For example, can be by mobile communication terminal reporting ability information, or the CQI reported is determined (for example, the CQI reported is and modulation Coding mode is corresponding).

Meanwhile when mobile communication system defines different wave, above-mentioned steps 402 include:

In the present embodiment, due to using the highest modulation coding scheme of mobile communication terminal as the second modulating-coding side Formula, so as to improve the transmission rate of downlink transmission data as far as possible.

For example, when the MCS Index for receiving network side equipment transmission is 22 corresponding to 256QAM, if mobile communication The highest modulating-coding that terminal is supported is 64QAM, then mobile communication terminal determines the first modulating-coding side according to mapping relations Formula is 256QAM, and mobile communication terminal will search the second modulation coding scheme from mapping relations record again at this time, at this In embodiment, which is 64QAM, and network side equipment will carry out downlink with the modulation coding scheme of 64QAM Transmission.If the highest modulating-coding that mobile communication terminal is supported is 256QAM, mobile communication terminal will be with the modulation of 256QAM Coding mode carries out downlink transfer.

At this point, the determination of spectrum efficiency can be configured according to actual needs, for example, in the present embodiment, it can be from the second modulation The corresponding MCS Index of coding mode selects the corresponding spectrum efficiency of a MCS Index to imitate as above-mentioned second target spectrum Rate, it is, of course, understood that generally selecting corresponding spectrum efficiency in the second modulation coding scheme to improve transmission rate A highest spectrum efficiency is as above-mentioned second target spectral efficiency, such as can choose spectrum efficiency is 5.04 as above-mentioned Second target spectral efficiency.In addition, it should be noted that, when mobile communication terminal ability only supports highest 64QAM, from above The maximum frequency deviation efficiency reached known to table two is 5.04, and practical 64QAM theory can reach 0.93*6=5.58. when terminal reports The corresponding spectrum efficiency of CQI index >=5.58 when, then select two MCS index=22 of table, select at this time second modulation Coding mode is 64QAM, and it is 5.58 that first object frequency efficiency, which can choose, that is, keeps the MCS of selection spectrum efficiency Index is constant, so that network side equipment carries out downlink biography with the spectrum efficiency of the modulation coding scheme of 64QAM and 5.58 It is defeated.

In the present embodiment, the modulation coding scheme that can be supported for different mobile communication terminal highest is different, Ke Yiding The different MCS table of justice, the modulation coding scheme that can also be supported according to all mobile communication terminal highests define maximum MCS table, Maximum MCS table is interpreted according to the modulation coding scheme that mobile communication terminal highest is supported, obtains mobile communication terminal pair The MCS table that should be supported.Such as the modulation coding scheme that mobile communication terminal highest is supported is 64QAM, and when interpreting MCS table, MCS The corresponding modulation system of Index=22 is 6.And the map record that MCS Index is 23 to 27 is nothing.
