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 that the data transmission amount is too large, the optical fiber carrying capacity required by data transmission is high, and the number of optical fibers is large in the related technology.

The method and the device are based on the same application concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.

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

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

s101, acquiring bit data and a channel type of the bit data.

It should be noted that the execution subject of the data transmission processing method in the embodiment of the present application may be a hardware device with data information processing capability and/or necessary software 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 includes, but is not limited to, a mobile phone, a computer, an intelligent voice interaction device, an intelligent household appliance, a vehicle-mounted terminal, and the like.

In the embodiments of the present 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 type of the bit data may be set according to actual situations, and the Channel type includes, but is not limited to, a Physical Broadcast Channel (PBCH), a Physical Downlink Control Channel (PDCCH), a Physical Downlink Shared Channel (PDSCH), a NULL Channel, a Primary Synchronization Signal (PSS) Channel, a Secondary Synchronization Signal (SSS) Channel, a Demodulation Reference Signal (DMRS) Channel, a Phase-tracking Reference Signal (PTRS) Channel, a Channel-state information Reference Signal (CSI RS) Channel, and the like, and is 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 present disclosure, after the bit data is obtained, a target Resource Block (RB) to be mapped, a target Resource Element (RE) in the target Resource Block, and target bit data to be mapped in the target Resource Element may be determined according to the bit data, so as to implement RE mapping processing of the bit data.

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

Optionally, a mapping relationship or a 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 pre-established, and after the bit data is obtained, the mapping relationship or the 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, which correspond 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 the 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 present disclosure, different channel types may correspond to different gain indexes, types of the gain indexes, and data definitions of target resource units, and after the channel type of the bit data is obtained, the gain indexes, the types of the gain indexes, and the data definitions of the target resource units may be determined according to the channel types. It is to be understood that each channel type may correspond to a gain index, and each gain index may include a plurality of gain values, i.e., each channel type may correspond to a plurality of gain values, and each channel type may correspond to a data definition of a target resource unit.

The gain index may be used to perform gain control on the bit data, and the type of the gain index may include a common index, an unshared index, and the like. For example, in a target resource block, when all target resource units correspond to the same gain index, the type of the gain index is a common index, and conversely, when all target resource units correspond to different gain indexes, the type of the gain index is a non-common index.

Wherein the data definition of the target resource unit can 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 a 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 pre-established, and after the channel type is obtained, the mapping relation or the 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 known 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

Wherein, power _ index is a gain index, data is bit data, pwd index is a common index, RB head is a target resource block header data channel, and it can be known that the size of the target resource block header data is 8 bits.

And S104, generating target resource unit data of a first preset position corresponding to the target resource unit and target resource block head data of a second preset position 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 can be appreciated that the target resource unit data, target resource block header data, is 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 a target resource unit and target resource block header data of a second preset bit corresponding to a target resource block can be generated, and therefore the bit data can be compressed into a plurality of first preset bits of target resource unit data and a plurality of second preset bits of target resource block header data.

The first preset position and the second preset position can be set according to actual conditions. Optionally, the first preset bit may be 9 bits, and the second preset bit may be 8 bits, so that 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.

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

It can be understood 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 one second preset bit, and each target resource unit may correspond to target resource unit data of one first preset bit, so that the plurality of target resource block header data and the plurality of target resource unit data corresponding to the bit data may be obtained. Further, the multiple target resource block header data and the multiple target resource unit data corresponding to the bit data may be sequentially arranged to obtain the frequency domain data to be transmitted.

For example, after the header data of the plurality of target resource blocks and the data of the plurality of target resource units corresponding to the bit data are arranged in sequence, 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 the target resource block head data with sequence number 0, RB1 head is the target resource block head data with sequence number 1, RE 0 is the target resource unit data with sequence number 0 under each target resource block, RE 1 is the target resource unit data with sequence number 1 under each target resource block, RE 2 is the target resource unit data with sequence number 2 under each target resource block, and so on, and the description is omitted here.

It can be understood that when the frequency domain data to be transmitted obtained by the method is subjected to data transmission, the bit data can be effectively compressed to reduce the data volume needing to be transmitted, the requirement on the bearing capacity of the optical fiber is low, and the number of the optical fibers needed for transmitting the data is small. For example, taking a Long Term Evolution (LTE) system with 100M (mega) data volume and 64 antennas as an example, the bandwidth of 16-stream frequency domain data is 120 × 273 × 14 × 16/0.0005 — 14.67648Gbps, and only one fiber with 25G bandwidth is needed to realize transmission. Where Gbps is one data transmission speed unit.

To sum up, 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 and the target bit data in the target resource block can be determined according to the bit data, 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 a plurality of first preset bits of target resource unit data and a plurality of second preset bits of target resource block header data can be generated according to the target bit data, the gain index, the type of the gain index and the data definition, so that the bit data can be compressed into the plurality of first preset bits of target resource unit data and the plurality of second preset bits of target resource block header data, the data compression effect is good, the amount of transmitted data is effectively reduced, the requirement on the carrying capacity of the optical fiber is reduced, and the amount of the optical fibers required for transmitting the data is reduced, networking costs and complexity are also reduced.

On the basis of any of the foregoing embodiments, the generating, in step S104, target resource unit data of a first preset bit corresponding to the target resource unit and target resource block header 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 may include the following two possible implementation manners:

in the mode 1, when the type of the gain index is the non-common index, the target resource unit data of the 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 the target resource block header data of the second preset bit corresponding to the target resource block can be generated according to the preset common gain index.

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

When the type of the gain index is a non-common index, it indicates that the gain index is inconsistent with a preset common gain index, and target resource unit data of a first preset bit corresponding to a 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.

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

When the type of the gain index is the common index, it indicates that the gain index is consistent with the preset common gain index, and may also generate target resource block header data of a second preset bit corresponding to the target resource block according to the preset common gain index, so that the target resource block header data may be used to indicate the common gain index, i.e., indicate the gain index.

It can be understood that, at this time, the target resource block header data may be used to indicate the gain index, and the gain index does not need to be indicated by the target resource unit data, and at this time, 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, namely the common index or the non-common index, and has high 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, obtaining a Physical Downlink Shared Channel (PDSCH) forming factor and a Physical Downlink Control Channel (PDCCH) forming factor.

Wherein the beamforming factor is used for beamforming (Beam Forming) 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 forming factor and a physical downlink control channel PDCCH forming factor can be obtained.

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

In the related technology, the data size of the PDSCH shaping factor and the PDCCH shaping factor is 16 bits, the data volume of the shaping factor is larger, the PDSCH shaping factor and the PDCCH shaping factor can be compressed to 7 bits from 16 bits by the method, and the data volume of the shaping factor can be reduced, so that the requirement on the bearing capacity of optical fibers is reduced, and the number of the optical fibers required for transmitting data is reduced.

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

It can be understood that the granularity of the beamforming factor affects the data amount of the beamforming factor, and the method can adjust the granularity of the PDSCH beamforming factor to further reduce the data amount of the PDSCH beamforming factor, thereby reducing the requirement on the carrying capacity of the optical fiber and reducing the number of optical fibers required for transmitting data.

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

For example, taking a Long Term Evolution (LTE) system with 100M data volume and 64 antennas as an example, the frequency domain data bandwidth of 16 streams is 120 × 273 × 14 × 16/0.0005 × 14.67648 Gbps. If each target resource block and each antenna use 4-bit Automatic Gain Control (AGC) factor, the data bandwidth of the 16-stream PDSCH forming factor and the 1-stream PDCCH forming factor is ((2 × 7+4) × 137 × 16 × 64+ (2 × 7+4) × 273 × 64)/0.0005 × 5.67936 Gbps. If the power is transmitted according to 16 bits, and the power table does not exceed 1200 bytes according to the prediction of 100 users, the total downlink bandwidth is 14.67648+5.67936+1200 × 8/0.0005-20.37504 Gbps, and only one optical fiber with the bandwidth of 25G is needed to realize transmission.

Therefore, the method can compress the PDSCH forming factor and the PDCCH forming factor from 16 bits to 7 bits, adjust the granularity of the PDSCH forming factor, and reduce the data volume of the forming factor, thereby reducing the requirement on the bearing capacity of optical fibers, reducing the number of optical fibers required by data transmission, and reducing the networking cost and the networking complexity.

On the basis of any of the above embodiments, as shown in fig. 3, an execution main body of the data transmission processing method according to the embodiment of the present disclosure may be a baseband processing Unit (BBU), where the BBU is connected to an Active Antenna Unit (AAU), and after acquiring frequency domain data and beamforming factor data, the BBU may transmit the frequency domain data and the beamforming factor data to an 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, and perform modulation and gain control processing on the bit data, and then the Active Antenna Unit may perform beamforming processing on the bit data according to the beamforming factor data.

It can be understood that, in the related art, most of the data is modulated and gain-controlled in the baseband processing unit, and the modulation and gain-controlled processing increases the amount of data to be transmitted, and has a high requirement on the carrying capacity of the optical fiber, and requires a large number of optical fibers for transmission.

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 obtaining 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, so as to obtain the frequency domain data to be transmitted. The high-level protocol processing module can perform high-level protocol processing on the bit data to obtain signaling bit data, the RLC/PDCP/MAC module can perform encryption and header addition processing on 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, compress the obtained forming factor data to obtain the forming factor data to be transmitted, and then transmit the frequency domain data to be transmitted and the forming factor data to 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) plus CP (Cyclic Prefix) module, a digital intermediate frequency module, and a radio frequency module, and after obtaining frequency domain data and forming 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 can be sent out on the antenna. The modulation module can analyze the frequency domain data to obtain bit data, channel types of the bit data, gain indexes and the like, then the modulation processing can be carried out on the bit data to obtain constellation point data, the gain control module can carry out gain control processing on the constellation point data according to the gain indexes, the beam forming module can carry out beam forming processing on the constellation point data after the gain control processing according to the forming factor data, the IFFT and CP module can carry out fast Fourier inverse transformation and cyclic prefix processing on the constellation point data after the beam forming, the digital intermediate frequency module can convert the constellation point data after the CP is added into an intermediate frequency signal, and the radio frequency module can convert the intermediate frequency signal into a radio frequency signal.
