The embodiment of the application provides a data transmission processing method, a data transmission processing device and a storage medium, which are used for solving the technical problems of overlarge data quantity transmitted in the related technology, higher optical fiber bearing capacity and more optical fibers required for data transmission.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

Fig. 1 is a flow chart of a data transmission processing method according to a first embodiment of the present application.

As shown in fig. 1, the data transmission processing method of the first embodiment of the present application includes:

S101, acquiring bit data and channel types of the bit data.

It should be noted that, the execution body of the data transmission processing method in the embodiment of the present application may be a hardware device having a data information processing capability and/or software necessary for driving the hardware device to operate. Alternatively, the execution body may include a workstation, a server, a computer, a user terminal, and other devices. The user terminal comprises, but is not limited to, a mobile phone, a computer, intelligent voice interaction equipment, intelligent household appliances, vehicle-mounted terminals and the like.

In the embodiment of the disclosure, multiple sets of bit data of different users may be obtained, and the bit data of different users may correspond to different channel types.

It is understood that the Channel types of the bit data may be set according to practical situations, and the Channel types include, but are not limited to, a physical broadcast Channel (Physical Broadcast Channel, PBCH), a physical downlink control Channel (Physical Downlink Control Channel, PDCCH), a physical downlink shared Channel (Physical Downlink Shared Channel, PDSCH), a NULL Channel, a primary synchronization signal (Primary Synchronization Signal, PSS) Channel, a secondary synchronization signal (Secondary Synchronization Signal, SSS) Channel, a demodulation reference signal (Demodulation Reference Signal, DMRS) Channel, a Phase-tracking reference signal (Phase-tracking reference signals, PTRS) Channel, a Channel state information reference signal (Channel-state information reference signal, CSI RS) Channel, and the like, which are not limited herein.

S102, determining a target resource block to be mapped, a target resource unit in the target resource block and target bit data to be mapped in the target resource unit according to the bit data.

In the embodiment of the disclosure, after obtaining the bit data, a target Resource Block (RB), a target Resource Element (RE) in the target Resource Block, and target bit data to be mapped in the target Resource Element to be mapped may be determined according to the bit data, so as to implement RE mapping processing of the bit data.

Wherein, the target resource block may be one or more, and each target resource block may include one or more target resource units, and the target resource units are used for storing target bit data to be mapped. For example, one target resource block may include 12 target resource units.

Optionally, a mapping relation or mapping table between the bit data and the target resource block to be mapped, the target resource unit in the target resource block and the target bit data to be mapped in the target resource unit may be established in advance, and after the bit data is acquired, the mapping relation or mapping table is queried, so that the target resource block to be mapped, the target resource unit in the target resource block and the target bit data to be mapped in the target resource unit corresponding to the bit data can be determined. It should be noted that the mapping relationship or the mapping table may be set according to actual situations.

S103, determining a gain index, the type of the gain index and the data definition of the target resource unit according to the channel type.

In the embodiment of the disclosure, different channel types may correspond to different gain indexes, types of gain indexes, and data definitions of target resource units, and after obtaining the channel types of the bit data, the gain indexes, the types of gain indexes, and the data definitions of the target resource units may be determined according to the channel types. It will be appreciated that each channel type may correspond to a gain index, each gain index may comprise a plurality of gain values, i.e. each channel type may correspond to a plurality of gain values, each channel type may correspond to a data definition of a target resource unit.

The gain index may be used to gain control the bit data, and the types of gain indexes may include a common index, a non-common index, and the like. For example, when all target resource units correspond to the same gain index in one target resource block, the type of the gain index is the common index at this time, whereas when all target resource units correspond to different gain indexes, the type of the gain index is the non-common index at this time.

Wherein the data definition of the target resource unit may be used to determine the data definition of the target bit data to be mapped in the target resource unit.

Optionally, a mapping relation or mapping table between the channel type and the gain index, the type of the gain index and the data definition of the target resource unit may be established in advance, and after the channel type is acquired, the mapping relation or mapping table is queried, so that the gain index, the type of the gain index and the data definition of the target resource unit corresponding to the channel type can be determined. It should be noted that the mapping relationship or the mapping table may be set according to actual situations.

For example, the mapping table between the channel type and the data definition of the target resource unit can be shown in table 1, and it can be seen from table 1 that the data size of the target resource unit is 9 bits (bit).

Table 1 mapping table between channel types and data definitions of target resource units

The power_index is a gain index, the data is bit data, the pwd index is a common index, the RB head is a target resource block header data channel, and the target resource block header data size is 8 bits.

S104, generating target resource unit data of a first preset bit corresponding to the target resource unit and target resource block head data of a second preset bit corresponding to the target resource block according to the target bit data, the gain index, the type of the gain index and the data definition.

It is understood that the target resource unit data, the target resource block header data are used to indicate bit data and gain index. When the target bit data, the gain index, the type of the gain index and the data definition are known, target resource unit data of a first preset bit corresponding to the target resource unit and target resource block head data of a second preset bit corresponding to the target resource block can be generated, so that the bit data can be compressed into target resource unit data of a plurality of first preset bits and target resource block head data of a plurality of second preset bits.

The first preset bit and the second preset bit can be set according to actual conditions. Alternatively, the first preset bit may be 9 bits, and the second preset bit may be 8 bits, and then the bit data may be compressed into a plurality of 9-bit target resource unit data and a plurality of 8-bit target resource block header data.

S105, arranging the plurality of target resource block head data and the plurality of target resource unit data corresponding to the bit data in sequence to obtain frequency domain data to be transmitted.

It may be appreciated that the bit data may be mapped to a plurality of target resource units in a plurality of target resource blocks, each target resource block may correspond to target resource block header data of a second preset bit, each target resource unit may correspond to target resource unit data of a first preset bit, and then a plurality of target resource block header data and a plurality of target resource unit data corresponding to the bit data may be obtained. Further, a plurality of target resource block header data and a plurality of target resource unit data corresponding to the bit data may be sequentially arranged to obtain frequency domain data to be transmitted.

For example, after the header data of the plurality of target resource blocks and the plurality of target resource unit data corresponding to the bit data are sequentially arranged, the obtained frequency domain data to be transmitted may refer to table 2, and as can be seen from table 2, each target resource block may include 12 target resource units.

Table 2 frequency domain data to be transmitted

Wherein RB0 head is target resource block header data with sequence number 0, RB1 head is target resource block header data with sequence number 1, RE 0 is target resource unit data with sequence number 0 under each target resource block, RE 1 is target resource unit data with sequence number 1 under each target resource block, RE 2 is target resource unit data with sequence number 2 under each target resource block, and so on, and will not be repeated here.

It can be understood that when the frequency domain data to be transmitted obtained by the method is transmitted, bit data can be effectively compressed to reduce the data quantity required to be transmitted, the requirement on the bearing capacity of the optical fiber is lower, and the quantity of the optical fiber required to transmit the data is less. For example, taking a data volume of 100M (mega), a long term evolution (Long Term Evolution, LTE) system with 64 antennas as an example, the bandwidth of the 16-stream frequency domain data is 120×273×14×16/0.0005= 14.67648Gbps, and transmission can be realized only by an optical fiber with a bandwidth of 25G. Wherein Gbps is a unit of data transmission speed.

In summary, according to the data transmission processing method of the embodiment of the present application, the target resource block to be mapped, the target resource unit in the target resource block, and the target bit data can be determined according to the bit data, and the gain index, the type of the gain index, and the data definition of the target resource unit can be determined according to the channel type of the bit data, and the target bit data, the gain index, the type of the gain index, and the data definition can be used to generate a plurality of target resource unit data of a first preset bit and a plurality of target resource block header data of a second preset bit, so that the bit data can be compressed into a plurality of target resource unit data of the first preset bit and a plurality of target resource block header data of the second preset bit.

Based on any of the foregoing embodiments, in step S104, the generating, according to the target bit data, the gain index, the type of the gain index, and the data definition, target resource unit data of the first preset bit corresponding to the target resource unit and target resource block header data of the second preset bit corresponding to the target resource block may include two possible implementations as follows:

In mode 1, when the type of the gain index is a non-shared index, target resource unit data of a first preset bit corresponding to the target resource unit can be generated according to the data definition, the target bit data and the gain index, and target resource block head data of a second preset bit corresponding to the target resource block can be generated according to the preset shared gain index.

In an embodiment of the present disclosure, a common gain index may be preset for each target resource block, and target resource block header data may be used to indicate the common gain index, and target resource unit data may be used to indicate bit data and gain index, or only bit data.

When the type of the gain index is a non-shared index, the gain index is inconsistent with a preset shared gain index, and target resource unit data of a first preset bit corresponding to the target resource unit can be generated according to the data definition, the target bit data and the gain index, so that the target resource unit data can be used for indicating the bit data and the gain index.

Target resource block header data of a second preset bit corresponding to the target resource block can be generated according to the preset common gain index, so that the target resource block header data can be used for indicating the common gain index.

In mode 2, when the type of the gain index is a common index, target resource unit data of a first preset bit corresponding to the target resource unit can be generated according to the data definition and the target bit data, and target resource block head data of a second preset bit corresponding to the target resource block can be generated according to the preset common gain index.

When the type of the gain index is the common index, the gain index is consistent with the preset common gain index, and target resource block head data of a second preset bit corresponding to the target resource block can be generated according to the preset common gain index, so that the target resource block head data can be used for indicating the common gain index, namely indicating the gain index.

It may be appreciated that, at this time, the target resource block header data may be used to indicate the gain index, and the gain index need not be indicated by the target resource unit data, and then the target resource unit data of the first preset bit corresponding to the target resource unit may be generated only according to the data definition and the target bit data, so that the target resource unit data is only used to indicate the bit data.

Therefore, the method can determine the generation mode of the target resource unit data according to the type of the gain index as the shared index or the non-shared index, and has higher flexibility.

On the basis of any of the above embodiments, as shown in fig. 2, after obtaining the frequency domain data to be transmitted in step S105, the method further includes:

s201, acquiring physical downlink shared channel PDSCH forming factors and physical downlink control channel PDCCH forming factors.

Wherein the shaping factor is used for Beam shaping (Beam shaping) of the bit data.

In the embodiment of the disclosure, when the channel type includes a physical downlink shared channel PDSCH and a physical downlink control channel PDCCH, a physical downlink shared channel PDSCH shaping factor and a physical downlink control channel PDCCH shaping factor may be obtained.

S202, compressing the PDSCH forming factors and the PDCCH forming factors from 16 bits to 7 bits.

In the related technology, the data size of the PDSCH forming factors and the PDCCH forming factors is 16 bits, and the data size of the forming factors is larger.

And S203, adjusting granularity of the PDSCH forming factors to obtain forming factor data to be transmitted.

It will be appreciated that the granularity of the form factor may affect the amount of data of the form factor, and the method may adjust the granularity of the PDSCH form factor to further reduce the amount of data of the PDSCH form factor, thereby reducing the load-bearing capacity requirements on the optical fiber and reducing the number of optical fibers required to transmit data.

Optionally, adjusting granularity of the PDSCH forming factor may include updating granularity of the PDSCH forming factor from 1 to 2.

For example, taking a 100m, 64-antenna long term evolution (Long Term Evolution, LTE) system as an example, the 16-stream frequency domain data bandwidth is 120×273×14×16/0.0005= 14.67648Gbps. If each target resource block and each antenna adopts a 4-bit automatic gain control (Automatic Gain Control, AGC) factor, the data bandwidths of the 16-stream PDSCH shaping factor and the 1-stream PDCCH shaping factor are ((2×7+4) ×137×16×64+ (2×7+4) ×273×64)/0.0005= 5.67936Gbps. If the power is transmitted according to 16 bits and according to 100 users, the estimated power meter is not more than 1200 bytes, the total downlink bandwidth is 14.676848+5.67936+1200 x 8/0.0005= 20.37504Gbps, and the transmission can be realized by only one optical fiber with the bandwidth of 25G.

Therefore, the method can compress the PDSCH forming factors and the PDCCH forming factors from 16 bits to 7 bits, and adjust the granularity of the PDSCH forming factors, so that the data volume of the forming factors can be reduced, the requirement on the bearing capacity of optical fibers is reduced, the number of optical fibers required for transmitting data is reduced, and the networking cost and the networking complexity are also reduced.

On the basis of any of the above embodiments, as shown in fig. 3, an execution body of the data transmission processing method in the embodiment of the present disclosure may be a baseband processing Unit (Base band Unit, BBU), where the baseband processing Unit is connected to an active antenna Unit (Active Antenna Unit, AAU), and after acquiring frequency domain data and shaping factor data, the baseband processing Unit may transmit the frequency domain data and the shaping factor data to the active antenna Unit, so that the active antenna Unit may analyze bit data, a channel type of the bit data, a gain index, and the like according to the frequency domain data, for performing modulation and gain control processing on the bit data, and then the active antenna Unit may further perform beamforming processing on the bit data according to the shaping factor data.

It can be understood that in the related art, most of the bit data is modulated and gain controlled in the baseband processing unit, and the modulation and gain control process increases the data volume to be transmitted, so that the requirement on the carrying capacity of the optical fibers is high, and the optical fibers with a large number of optical fibers are required to be transmitted.

Optionally, as shown in fig. 3, the baseband processing unit may include a higher layer protocol processing module, an RLC/PDCP/MAC module, a coding module, a scrambling module, and an RE mapping module, and after acquiring the bit data, the obtained bit data may be sequentially input into the higher layer protocol processing module, the RLC/PDCP/MAC module, the coding module, the scrambling module, and the RE mapping module to obtain frequency domain data to be transmitted. The high-layer protocol processing module can perform high-layer protocol processing on the bit data to obtain signaling bit data, the RLC/PDCP/MAC module can encrypt and pack the signaling bit data, the coding module can perform coding processing on the bit data, the scrambling module can perform scrambling processing on the coded bit data, and the RE mapping module can perform RE mapping processing on the scrambled bit data.

After the frequency domain data to be transmitted is obtained, the baseband processing unit can also obtain the forming factor data, and compress the obtained forming factor data to obtain the forming factor data to be transmitted, and then the frequency domain data to be transmitted and the forming factor data to be transmitted can be transmitted to the active antenna unit.

Optionally, as shown in fig. 3, the active antenna unit may include a modulation module, a gain control module, a beam forming module, an IFFT (Inverse Fast Fourier Transform inverse fast fourier transform) plus CP (Cyclic Prefix) module, a digital intermediate frequency module, and a radio frequency module, and after obtaining frequency domain data and form factor data, the obtained frequency domain data may be sequentially input to the modulation module, the gain control module, the beam forming module, the IFFT plus CP module, the digital intermediate frequency module, and the radio frequency module, so as to obtain a radio frequency signal that may be sent on the antenna. The modulation module may analyze the frequency domain data to obtain bit data, a channel type of the bit data, a gain index, etc., then may modulate the bit data to obtain constellation point data, the gain control module may perform gain control processing on the constellation point data according to the gain index, the beamforming module may perform beamforming processing on the constellation point data after the gain control processing according to the beamforming factor data, the IFFT and CP module may perform inverse fast fourier transform and cyclic prefix processing on the constellation point data after the beamforming, the digital intermediate frequency module may convert the constellation point data after the CP addition into an intermediate frequency signal, and the radio frequency module may convert the intermediate frequency signal into a radio frequency signal.
