For example, when data corresponding to PUCCH is transmitted in a 5G network environment and a 4G network environment, module call conditions using the communication data processing apparatus in two different network environments are as follows: in a 4G network environment, a first storage unit, a scrambling unit, a modulation unit, a sequence generation unit, a complex multiplication unit, a resource mapping unit, a DFT unit, an IFFT unit and a third storage unit are required to be called according to an LTE standard; in a 5G network environment, according to the NR standard, in addition to the aforementioned units that need to be called in the 4G network environment, a CRC adding unit, a Polar encoding unit, or smallblock encoding unit, a second storage unit, and a second rate matching unit need to be called.

Based on the same inventive concept, the embodiment of the application also provides a communication data processing method compatible with the LTE standard and the NR standard for controlling the communication data processing device compatible with the LTE standard and the NR standard. The implementation of the solution provided by the method is similar to the implementation described in the above method, so the specific limitation in the embodiments of the communication data processing method provided below for one or more embodiments of the communication data processing method compatible with the LTE standard and the NR standard may be referred to above for the limitation of the communication data processing apparatus compatible with the LTE standard and the NR standard, which is not repeated herein.

In an exemplary embodiment, please refer to fig. 7, a communication data processing method compatible with LTE standard and NR standard is provided, and the method is applied to a microcontroller in a baseband processor in a communication chip in a terminal 102 as shown in fig. 1, and the method includes a step 702 and a step 704, where:

Step 702, determining a target standard identifier according to the current network environment of the terminal.

The target standard is identified as an NR standard if the network environment in which the terminal is currently located is a 5G network environment, and as an LTE standard if the network environment in which the terminal is currently located is a 4G network environment; or the network environment where the terminal is currently located comprises a 4G network signal and a 5G network signal, the terminal can select a better network signal as a communication signal according to the strength and the quality of the two network signals.

And step 704, controlling the communication data processing device to process the uplink communication data according to the target standard mark to obtain target communication data.

Exemplary, source bit data corresponding to the PUCCH and the PUSCH are obtained, and corresponding units are called to perform corresponding processing according to the target standard identification; the process provided by step 704 may include steps A1 through A2:

a1, acquiring source bit data to be processed;

And step A2, controlling the communication data processing device to process the source bit data according to the target standard mark to obtain target communication data.

In a possible implementation manner, referring to fig. 3 and fig. 6, in step A2, the process of controlling the communication data processing device to process the source bit data according to the target standard identifier to obtain the target communication data includes steps B1 to B14:

And step B1, acquiring and storing source bit data through a first storage unit. Executing steps B3 to B6 and steps B8 to B13 when the source bit data meets a first preset condition; the first preset condition includes that when the channel type corresponding to the source bit data is PUCCH, the target standard mark is NR standard, or the channel type corresponding to the source bit data is PUSCH; and when the source bit data source does not meet the first preset condition, executing the steps B7 to B13.

In the LTE standard, the PUCCH carries 11 bits of source bit data at most, and the source bit data is directly scrambled without CRC code addition, channel coding, and rate matching.

And step B2, performing check code adding processing on the source bit data through a check code adding unit to obtain checked data.

And step B3, transmitting the checked data to a target coding unit in a plurality of coding units according to the standard identifier, wherein the target coding unit corresponds to the target standard identifier, the target coding unit corresponds to a target channel type, and the target channel type is the channel type corresponding to the initial communication data.

Step B4, encoding the checked data through a target encoding unit to obtain encoded data; the encoded data is stored by the second storage unit.

And step B5, acquiring the encoded data from the second storage unit, and sending the encoded data to the target rate matching unit according to the target standard identifier so that the target rate matching unit can perform rate matching on the encoded data to obtain matched data, wherein the target rate matching unit corresponds to the target standard identifier.

Step B6, scrambling the matched data through a scrambling unit to obtain scrambled data;

and step B7, scrambling the source bit data through a scrambling unit to obtain scrambled data.

And step B8, modulating the scrambled data through a modulating unit to obtain modulated data.

And step B9, the modulated data is sent to a DFT unit so that the DFT unit can perform discrete Fourier transform processing on the modulated data to obtain transformed data.

Step B10, generating sequence data by a sequence generating unit and sending the sequence data to a complex multiplying unit.

Step B11, when the source bit data meets a second preset condition, sending the modulated data to a complex multiplication unit for the complex multiplication unit to carry out complex multiplication on the modulated data and the sequence data, so as to obtain complex multiplied data; the second preset condition includes that the target standard is identified as an NR standard, or that the target standard is identified as an LTE standard and the target channel type is not PUSCH.

According to the rule in the LTE standard, the pilot sequence in the communication data corresponding to the PUCCH needs to be multiplied with the modulated data, and the pilot sequence in the communication data corresponding to the PUSCH does not need to be multiplied with the modulated data; according to the regulations in the NR standard, pilot sequences in communication data corresponding to PUCCH and PUSCH are required to be multiplied with modulated data, so when source bit data meets preset conditions, the corresponding modulated data is sent to a multiplying unit for complex multiplication, and when the preset conditions are not met, the modulated data is only sent to a DFT unit.

And step B12, performing resource mapping processing on the complex multiplied data and/or the transformed data through a resource mapping unit to obtain mapped data, and performing inverse Fourier transform processing on the mapped data through an IFFT unit to obtain time domain data.

And step B13, storing the time domain data into a third storage unit.

And step B14, performing decision-balancing feedback processing on the time domain data through a decision-balancing feedback module to obtain target communication data.

For example, when the target communication data corresponds to the SRS, the procedure provided in step 704 may include steps C1 to C4:

step C1, generating initial sequence data through a sequence generating unit;

And step C2, performing resource mapping processing on the initial sequence data through a resource mapping unit to obtain mapped data, and performing inverse Fourier transform processing on the mapped data by an IFFT unit to obtain time domain data.

And step C3, storing the time domain data into a third storage unit.

And step C4, performing decision-balancing feedback processing on the time domain data through a decision-balancing feedback module to obtain target communication data.

It should be noted that, the mapped data generally includes data corresponding to a plurality of channels, and the mapped output obtained in step C2 may further include partial data corresponding to PUCCH and partial data corresponding to PUSCH, in addition to partial data corresponding to SRS; correspondingly, the mapped data obtained in the step B12 may also include part of the data corresponding to the SRS. It will be appreciated that the processing of the data of the communication data processing apparatus may be performed simultaneously for a plurality of channels of data, and steps C2 to C4 and steps B12 to B14 may be the same part of the processing of the data of the communication data processing apparatus.
