Description

Data transmission system and method, MAC architecture and implementation method thereof

Technical field

The present application relates to the field of communications, for example, to a data transmission system and method, a Media Access Control (MAC) architecture, and an implementation method thereof.

Background technique

The mobile communication network is experiencing an inflated growth of terminal data traffic. In the future, the communication system can achieve ultra-high rate, large throughput, ultra-high reliability, ultra-low latency and other indicators to provide users with the best experience. Thus, the 5G system proposes a target with a peak rate of 10G and a delay of milliseconds.

5G systems can also support more types of services. Among them, there are three typical businesses:

Enhanced mobile broadband (eMBB) technology, deployment scenarios for indoor hotspots, dense urban areas, rural areas, urban macro stations and highways. eMBB technology requires very high throughput and low latency. For both uplink and downlink, the target delay for the user plane is 4ms.

Massive Machine Type Communications (MMTC) technology, the deployment scenario can be a densely connected urban area. mMTC requires large and continuous coverage. At the same time, mMTC has a high demand for power saving for users.

Ultra-Reliable and Low Latency Communications (URLLC) technology, deployment scenarios may be special scenarios, such as: medical. URLLC is very sensitive to latency and requires very high reliability. For the uplink and downlink, the target delay of the user plane is 0.5ms.

It can be seen that 5G wants to support multiple services to meet different transmission requirements.

At the same time, the current use efficiency of the frequency band below 6 GHz is close to the theoretical limit, so both academia and industry believe that the higher frequency band mmWave will be an important way to achieve future communication. mmWave not only has a large frequency band available, but also has a short transmission distance. In order to adapt to the transmission characteristics of mmWave and the requirements of services, 5G may support multiple physical layer technologies, such as non-orthogonal OFDM technology, short TTI, and so on. Moreover, different services may require different air interface subsets (AIS), which refers to radio access technology and physical layer processing in a certain frequency band, 5G system. There can be multiple AISs across the entire frequency band. For example, a URLLC service requires a short TTI to meet its user plane delay requirements, while an eMBB service requires a long TTI to meet its high throughput requirements.

Therefore, when there are three types of services: eMBB, URLLC, and mMTC, and there are three corresponding physical layer technologies AIS-1, AIS-2, and AIS-3, the user plane and the physical layer are processed as shown in FIG. 1.

The eMBB, URLLC, and mMTC services are processed by PDCP and RLC, mapped into logical channels, and mapped to the physical channels AIS-1, AIS-2, and AIS-3 through MAC scheduling, processed by the physical layer, and transmitted through the wireless carrier. Go out. The MAC is not only responsible for allocating resources for the service, but also mapping the service to the corresponding physical channel. Then, the MAC not only satisfies the service Qos through scheduling, but also undertakes the physical layer.

However, the original MAC architecture is only designed for low-frequency LTE systems and can only support a single physical layer technology.

The independent MAC layer device 202 can be configured to implement functions such as HARQ, random access, and the like.

In summary, the present embodiment proposes a network-side MAC architecture design scheme that supports multiple services, adapts to various physical layer technologies, and satisfies service requirements.

The following is described in detail in conjunction with Embodiments 2-4.

Example 2

Assume that there are three types of services: eMBB, URLLC, and mMTC in a 5G cell. To meet service requirements, eMBB uses physical technologies such as long TTI, such as AIS-1, and URLLC uses physical technologies such as short TTI, such as AIS-2. mMTC uses physical technologies such as competitive non-orthogonal random access technology, such as AIS-3.

Considering that three services adopt different physical technologies and require three independent MAC layer device adaptations, the user plane and physical layer architecture can be represented as FIG. 4. The public MAC is responsible for mapping the eMBB, URLLC, and mMTC services to AIS-1, AIS-2, and AIS-3, and allocating the location and size of the resources and the multiplexing and solution of the data packets on the corresponding physical resources. The multiplexing function; the independent MAC is responsible for functions such as HARQ and random access.

The network side processes the data packet as follows:

For the downlink, when the eMBB, URLLC, and mMTC services have data to transmit, the public MAC may be based on a proportional fair algorithm. According to the priority of each service and the amount of data to be transmitted, each TTI determines the resource size of each service, Location and corresponding physical layer channel processing.

For example, the public MAC decides to map the eMBB service to AIS-1 and allocate the resource size and location on the frequency band in which AIS-1 is located. The public MAC decides to map the URLLC service to AIS-2 and allocate the resource size and location on the frequency band where AIS-2 is located. The public MAC decides to map the mMTC service to AIS-3 and allocate the resource size and location on the frequency band in which AIS-3 is located.

Thus, the frequency bands of AIS-1, AIS-2, and AIS-3 will change for each TTI according to the scheduled result. As shown in Figure 5.

Moreover, if the public MAC address can also be mapped to the AIS-2 for the eMBB service when the URLLC resource remains, the resource size and location are allocated on the frequency band in which the AIS-2 is located. Moreover, within one TTI, the public MAC can also map the eMBB service and the URLLC service to the AIS-2 at the same time, and allocate the resource size and location on the frequency band in which the AIS-2 is located.

Then, the public MAC multiplexes the data packet according to the scheduling result, and submits it to the corresponding independent MAC.

The independent MAC is processed by HARQ and mapped to the corresponding AIS according to the scheduling result.

Finally, after physical layer processing, it is transmitted to the user on the corresponding wireless carrier.

For the uplink, the physical layer obtains data on the carrier, processes it through AIS, and submits it to the corresponding independent MAC.

The independent MAC is processed by HARQ and submits the correct data packet to the public MAC.

The public MAC is demultiplexed and submitted to the RLC.

When the cell does not have a certain service, the corresponding independent MAC address may be deleted. For example, when the cell does not have the URLLC service, its user plane and physical layer architecture may be represented as FIG. 6.

Of course, when a certain service is added to a cell, a corresponding independent MAC can be added.

Example 3

It is assumed that there are two frequency bands, one high frequency band and one low frequency band in a certain 5G cell, and the corresponding physical layer processing is also different, and there are AIS-1 and AIS-2. Then two independent MAC adaptations, then the user plane and physical layer architecture can be represented as Figure 7.

The public MAC can determine whether the data is transmitted in the high frequency band or in the low frequency band through scheduling, and submit the data to the corresponding independent MAC, and the independent MAC is responsible for mapping to the corresponding AIS.

When the high frequency band is idle, the public MAC can split more data to the high frequency band; when the channel quality of the high frequency band deteriorates, the public MAC schedules data to the low frequency band. This enables flexible application of high and low frequency bands.

Example 4

When the network adopts a deployment mode in which a central unit-distributed unit (CU-DU) is separated, the MAC architecture can be well applied. The network deployment is shown in FIG. 8.

The CU may have functions such as PDCP, RLC, and public MAC, and the DU may have independent MAC, physical layer operation, and radio unit.

The CU has a public MAC, which can flexibly schedule resources on DU1, DU2, and DU3, and implement solutions such as COMP and CA, which facilitates resource coordination between DUs. The DU has an independent MAC, and the DUs are independent. The deployment of the DU does not affect the CU and other DUs.

This deployment method not only has low DU cost, but also wireless performance can be optimized.

Step S904, the independent MAC layer device maps the to-be-transmitted data to the physical layer device, where the independent MAC layer device is configured to adapt to the physical layer processing procedure.

Optionally, the foregoing common MAC layer device manages the foregoing independent MAC layer device, where the foregoing management includes at least one of: deleting the independent MAC layer device, and adding the independent MAC layer device.
