Description
Technical Field
The embodiment of the application relates to the field of data communication, in particular to a data transmission method, a data transmission device, a data transmission system, electronic equipment and a storage medium.
Background
With the large-area spreading of 5G, the industrial application field of 5G is wider and wider, more communication transmission in the future depends on 5G wireless technology, and the wired optical fiber deployment is slowly abandoned, so that the flexibility of communication deployment is improved.
The original requirement for 5G is to meet the user requirements of different user models for different scenarios, such as some traffic is insensitive to time delay and sensitive to throughput bandwidth requirements. Some traffic is exceptionally sensitive to time delays (such as in the context of industrial applications), but not to frequency offset due to movement speed. The most commonly used high throughput scenario in 5G today mostly uses a 256QAM mapping table, but this mapping table sacrifices reliability, and in 3GPP specifications, the Block Error Rate (BLER) is 10e-5 (0.001%) if industrial level reliability is to be achieved. While in a high-mobility high-reliability scenario, lowSE64QAM is generally adopted, the higher the Spectral efficiency is for the same MCS Index value, the higher the throughput is, but the higher the probability of packet loss and packet error is due to the reduction of the check bit.
However, the future UE (User Equipment) is not all UE with a single attribute, and if a UE with a mixed use is used for transmitting a monitoring video (high throughput is needed) and performing automatic driving (high response speed is needed), the UE cannot singly use a table to perform service, but the conventional technical scheme can only interact through RRC to achieve the effect of changing the table, but if RRC participation is needed for each change of the table, the signaling interaction of the network frequently causes heavy load and large delay of the network, which is not suitable for parameters that change rapidly.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, as will be appreciated by those of ordinary skill in the art, in the various embodiments of the present application, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation of the present application, and the embodiments may be mutually combined and referred to without contradiction.
A first embodiment of the present invention relates to a data transmission method, which is applied to a first device, where in this embodiment, the first device and the second device are a network and a User Equipment (UE), respectively.
The specific flow is shown in figure 1:
and step 101, changing a field related to a modulation strategy in a signal to be transmitted according to a service attribute of a data packet to be transmitted, wherein the field related to the modulation strategy is a preset number of a modulation and coding strategy table corresponding to the service attribute.
Data has different traffic properties, such as the scene URLLC for industrial applications, is extremely sensitive to time delay, and therefore requires high-speed low-delay quadrature amplitude modulation (QAM, quadrature Amplitude Modulation); such as high throughput QAM required for transmitting video files, most of the high throughput scenarios currently used in 5G mostly employ a 256QAM correspondence table, but such a correspondence table sacrifices reliability (accuracy).
As shown in fig. 2, 3 and 4, table1 corresponds to 64QAM, table2 corresponds to 256QAM, and table3 corresponds to LowSE64QAM.
Taking the above three tables as an example, where the throughput rank is table2> table1> table3, the reliability table2< table1< table3. That is, for the same MCS Index value, the higher Spectral efficiency, the higher the throughput, but the higher the probability of packet loss and packet errors due to the reduction of check bits.
The use of modulation and coding strategies (MCS, modulation and Coding Scheme) corresponding to the traffic attributes of the application scenarios in different application scenarios is undoubtedly a technical approach, but when multiple different MCSs need to be used in one application scenario, how to quickly transform the MCS needs to be considered, and the traffic demands are not affected.
The conventional technical solution is to interact between two ends of transmission through radio resource control (RRC, radio Resource Control) signaling, for example, in the service model of fig. 5, a represents data requiring high throughput, and B represents data requiring high reliability, in the service model, MCS needs to be changed six times, if the conventional RRC signaling needs to be interacted six times, but there is a problem that a round trip is required to be opened from RRC of a network to RRC of a terminal through RRC signaling, a delay of signaling itself is long, and when signaling is completed, a time of data B is delayed, which may cause a large transmission delay.
In the present embodiment, the service attribute requirements and the MCS table are mapped, and the number corresponding to the MCS table is preset. According to the service attribute requirement of the data packet to be transmitted, adding the number corresponding to the service attribute requirement into the field of the signal, and if the data packet is downlink data transmission, namely adding a field related to a modulation strategy into the field of downlink control information (DCI, downlink Control Information), changing the field into the number corresponding to the service attribute of the data packet to be transmitted.
Specifically, firstly, judging whether the service attribute of the data packet to be transmitted is consistent with the default service attribute:
if they are consistent, there are three processing modes:
1. changing the field related to the modulation strategy into a number corresponding to a default service attribute;
for example, the default service attribute is set to be the service attribute corresponding to table2, the number corresponding to table2 is set to be 2, and the field related to the modulation policy is changed to be 2.
2. Changing a field related to the modulation strategy to a special value representing a default service attribute;
for example, if the number corresponding to table1 is 1, the number corresponding to table2 is 2, and the number corresponding to table3 is 3, a special value is set to 0, which represents a default service attribute.
3. No field is carried about the modulation strategy.
And if the modulation strategy is inconsistent, changing the field related to the modulation strategy into the number of the modulation and coding strategy table corresponding to the service attribute to be transmitted.
And step 102, transmitting the signal containing the data packet to be transmitted to the second device through the bottommost layer of the protocol stack of the first device.
In the conventional scheme described in step 101, the MCS table is changed through RRC signaling interaction, taking the service model of fig. 5 as an example, six changes of MCS generate a lot of interactions, and these interactions need to be processed at the RRC layer of the protocol stack, as shown in fig. 6, that is, a round trip from the RRC of the first device to the RRC of the second device needs to be performed, so that the delay of signaling transmission is longer, and especially, the transmission of high reliability data is affected.
In this embodiment, the processing is performed at the bottommost layer of the protocol stack, that is, the PHY layer, as shown in fig. 7, without going through other protocol layers, so that the transmission time is significantly reduced, and the transmission speed is faster.
Compared with the related art, the embodiment of the invention ensures that the transmitted data is free from signaling interaction by changing the field of the modulation strategy in the signal, thus being capable of acquiring the modulation strategy suitable for the service attribute of the data packet, reducing the interaction process, simplifying the mode of changing the modulation strategy and reducing the changing time; meanwhile, the bottommost layer of the protocol stack is adopted to process data and transmit the data, which is different from the former mode that instructions are needed to be interacted through all layers of the protocol stack, so that the transmission flow and time are obviously reduced, the effect of transmitting the data is not influenced by overlong time delay when the equipment faces to transmitting the data with high reliability, and the time delay is further reduced.
The second embodiment of the present invention relates to a data transmission method, which is applied to a second device, and the specific flow is shown in fig. 8:
step 801, receiving a signal containing a data packet to be transmitted through the bottommost layer of a second device protocol stack, wherein the signal comprises a preset field of a number of a demodulation strategy of the data packet to be transmitted;
step 802, demodulating the signal according to the number of the demodulation strategy to obtain the data in the data packet.
In this embodiment, the second device serves as a data receiving side, receives a signal from the bottom layer of the protocol stack, and obtains an MCS table according to a field related to a demodulation policy in the signal, so as to demodulate the received signal, and obtain a data packet in the signal.
Compared with the related art, the method and the device have the advantages that the MCS table corresponding to the service attribute of the transmission data packet is determined through the bottommost processing signal of the protocol stack in an instruction interaction mode without passing through the whole protocol stack, so that the transmission delay is reduced; meanwhile, corresponding numbers are acquired from the fields of the signaling to determine an MCS table corresponding to the signal, which is different from the mode of carrying out multiple times of interaction of the signaling in the related art, so that the time delay is further reduced, and the transmission process is reduced.
It should be noted that, the present embodiment and the first embodiment correspond to each other, the present embodiment is applied to the second device, which corresponds to the receiving data side, and the first embodiment is applied to the first device, which corresponds to the data sending side, so that the relevant details in the first embodiment may also be applied to the present embodiment, and the same technical scheme will not be repeated in the present embodiment.
The above steps of the methods are divided, for clarity of description, and may be combined into one step or split into multiple steps when implemented, so long as they include the same logic relationship, and they are all within the protection scope of this patent; it is within the scope of this patent to add insignificant modifications to the algorithm or flow or introduce insignificant designs, but not to alter the core design of its algorithm and flow.
The third embodiment of the present invention relates to a data transmission method, where a service model is shown in fig. 5, a represents data with high throughput requirements, corresponding to mcs-table=2, b represents data with high reliability requirements, corresponding to mcs-table=3, and a field related to modulation and demodulation of DCI in downlink transmission data is set as mcs-table index, and a default service requirement is mcs-table=2.
Step1, when the first device sends the 0 th to 3 rd packets of data, the data packet is determined to be the data requiring high throughput, and the current default service attribute is mcs-table=2, which is the same as the 0-3 packets of data, so that the first device can adopt the following alternative scheme to declare that the information receiver is unchanged at the moment mcs-table:
scheme 1: DCI does not carry the mcs-table index, and represents that the mcs-table is unchanged, and a default value is adopted.
Scheme 2: DCI carries the mcs-table index, but takes a value of 0 (as a special value), which indicates that the mcs-table is unchanged, and adopts a default value.
Scheme 3: the DCI carries the mcs-table index, but the value is 2, and the terminal is explicitly informed that the mcs-table=2 is adopted.
Step2, when the 4 th packet is sent, the data with high reliability is judged to be needed, and the current network default configuration is that the mcs-table=2 does not meet the requirement, so that the DCs of the first device carry the mcs-table index, but the value is 3, and the terminal is explicitly informed of adopting the mcs-table=3.
Step3, when the 5 th packet is sent, the data with high throughput is judged to be needed, and the default service attribute is mcs-table=2, which is the same as the requirement of the 5 th packet, so that the first device can adopt the following alternative scheme to declare that the mcs-table is unchanged at the moment of the information receiver:
scheme 1: DCI does not carry the mcs-table index, and represents that the mcs-table is unchanged, and a default value is adopted.
Scheme 2: DCI carries the mcs-table index, but takes a value of 0 (as a special value), which indicates that the mcs-table is unchanged, and adopts a default value.
Scheme 3: the DCI carries the mcs-table index, but the value is 2, and the terminal is explicitly informed that the mcs-table=2 is adopted.
The data transmission is completed by repeating the above steps.
When the second device receives DCI1_1, the value of the mcs-table index needs to be checked, and then the correct mcs-table is selected for demodulation.
The fourth embodiment of the present invention relates to a data transmission method, where a service model is shown in fig. 5, a represents data with high throughput requirements, corresponding to mcs-table=2, b represents data with high reliability requirements, corresponding to mcs-table=3, and a field related to modulation and demodulation of DCI in downlink transmission data is set as mcs-table index, and a default service requirement is mcs-table=1. Wherein the difference from the third embodiment is the default traffic requirement.
Step1, when the first device sends the data from the 0 th packet to the 3 rd packet, the data is judged to be the data with high throughput, and the default service attribute is mcs-table=1, the requirements are not met, and the DCI carries mcs-table index, but the value is 2, and the terminal is explicitly informed of the fact that the mcs-table=2 is adopted.
Step2, when the 4 th packet is sent, the data with high reliability is judged to be needed, and the default service attribute mcs-table=1 is not satisfied, so that the DCI of the first device carries mcs-table index, but the value is 3, and the terminal is explicitly informed of the fact that the mcs-table=3 is adopted.
Step3, when the 5 th packet is sent, the data with high throughput is judged to be needed, and the default service attribute is that the mcs-table=1 is not satisfied, at this time, the DCI carries the mcs-table index, but the value is 2, and the terminal is explicitly informed of the fact that the mcs-table=2 is adopted.
The data transmission is completed by repeating the above steps. When receiving DCI, the second device needs to check the value of the mcs-table index, and then selects the correct mcs-table for demodulation.
The fourth embodiment of the present invention relates to a data transmission method, where a represents data with high throughput requirements, corresponding to mcs-table=2, b represents data with high reliability requirements, corresponding to mcs-table=3, c represents data with medium reliability and medium throughput requirements, corresponding to mcs-table=1, a field related to modulation and demodulation of DCI set in downlink transmission data is mcs-table index, and a default service requirement is mcs-table=2, as shown in fig. 9.
Step1, when the first device sends the data from the 0 th packet to the 3 rd packet, the data is judged to be the data requiring high throughput, and the default service attribute is that the mcs-table=2 just meets the requirement, so the first device can adopt the following alternative scheme to declare that the mcs-table is unchanged at the moment of the information receiver:
scheme 1: DCI does not carry the mcs-table index, and represents that the mcs-table is unchanged, and a default value is adopted.
Scheme 2: DCI carries the mcs-table index, but takes a value of 0 (as a special value), which indicates that the mcs-table is unchanged, and adopts a default value.
Scheme 3: the DCI carries the mcs-table index, but the value is 2, and the terminal is explicitly informed that the mcs-table=2 is adopted.
Step2, when the 4 th packet is sent, the data with high reliability is judged to be needed, and the default service attribute mcs-table=2 is not satisfied, so that the first device DCI carries the mcs-table index, but the value is 3, and the terminal is clearly informed of the fact that the mcs-table=3 is adopted.
Step3, when the 5 th packet is sent, the data is judged to be the data with throughput in the reliability in need, and the default service attribute mcs-table=2 does not meet the requirement, so that the first device DC carries the mcs-table index, but the value is 1, and the terminal is explicitly informed of adopting the mcs-table=1.
Step4, when sending the 6 th packet, judging that the data needs high throughput, and the default service attribute is that mcs-table=2 is just enough, so that the first device can adopt the following alternative scheme to declare the information receiver:
scheme 1: DCI does not carry the mcs-table index, and represents that the mcs-table is unchanged, and a default value is adopted.
Scheme 2: DCI carries the mcs-table index, but takes a value of 0 (as a special value), which indicates that the mcs-table is unchanged, and adopts a default value.
Scheme 3: the DCI carries the mcs-table index, but the value is 2, and the terminal is explicitly informed that the mcs-table=2 is adopted.
The data transmission is completed by repeating the above steps. When receiving DCI, the second device needs to check the value of the mcs-table index, and then selects the correct mcs-table for demodulation.
