Description

Method, device and equipment for multiplexing and demultiplexing data of wireless access network
Technical Field
The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a device for multiplexing and demultiplexing data in a radio access network.
Background
The mobile communication network faces the expansion type increase of terminal data traffic, the construction of the 5G network needs to achieve indexes such as ultrahigh speed, large throughput, ultrahigh reliability, ultralow time delay and the like, and provides optimal experience for users, the service capacity and the deployment strategy of the mobile network face huge pressure and challenge due to the requirements, and operators need to enhance the existing network deployment and communication technology on one hand and hope to accelerate the popularization and network expansion of new technologies on the other hand, so that the purpose of rapidly improving the network performance is achieved.
The 4G Network architecture is flat, and a Radio Network Controller (RNC for short) is removed, so that the eNodeB is directly connected with a core Network, and the time delay is reduced. In addition to further sinking the functions of the core Network, the Network architecture of the future 5G tends to adopt Centralized, collaborative, cloud-computing and Network deployment of a green Radio Access Network (C-RAN for short). The network architecture adopts a cooperation and virtualization technology to realize resource sharing and dynamic scheduling, achieves low-cost, high-bandwidth and high-flexibility operation, is an ultra-dense heterogeneous network with a smaller and smaller cell range in 5G, and can conveniently realize effective cooperation among cells.
In 4G, the C-RAN architecture generally includes a centralized baseband Unit (Base Band Unit, abbreviated as BBU) and a Radio Remote Unit (Radio Remote Unit, abbreviated as RRU), an Interface between the BBU and the RRU employs a Common Public Radio Interface (CPRI), and the CPRI Interface transmits IQ signals processed by physical layer coding modulation and the like, and has large requirements on transmission delay and bandwidth. If the 5G air interface rate is increased to tens of Gbps, the traffic demand of the CPRI interface is increased to the level of Tbps, which brings huge pressure on the network deployment cost and the deployment difficulty. Therefore, in the 5G technology, the functions of the BBU and the RRU need to be redefined, such as placing part of the user plane function of layer 2 in the BBU and part in the RRU. In the present invention, the BBU and the RRU after the function is re-programmed are respectively named as a Centralized processing Unit (abbreviated as CU) and a Distributed processing Unit (abbreviated as DU).
One of the methods for deploying the user plane function in the DU and CU is to place the functions with low time delay requirement, including data header compression, encryption integrity protection, retransmission, sender sequence number maintenance and receiver ordering for high-level service data, automatic Repeat Request (ARQ for short), etc. on the CU side; the functions of high delay requirement and fast following of air interface resources and air interface Quality, including data segmentation, concatenation, re-segmentation, reassembly, multiple logical channel multiplexing, hybrid Automatic Repeat reQuest (HARQ) and the like, are placed on the DU side, so that the data transmission of the CU and the DU is closer to the air interface capability, the Quality of Service (QoS for short) of the Service is satisfied, and the transmission characteristics between the CU and the DU are satisfied.
In LTE, data segmentation, concatenation, re-segmentation, and reassembly are accomplished in a Radio Link Control (RLC) protocol; the multi-logical channel multiplexing and HARQ are performed in a Media Access Control (MAC) layer. The RLC sender carries out data segmentation, concatenation and re-segmentation according to the transmittable data volume of a certain transmission opportunity fed back by the MAC; the RLC receiver performs ordering and reassembly of RLC data received from the MAC as shown in fig. 1. Therefore, the RLC Sequence Number (RLC SN) is introduced in the above processing procedure, so that the RLC receiver completes data reassembly; and the MAC and the RLC frequently interact to meet the requirement of fast following of air interface resources and air interface quality.
However, the Packet Data Convergence Protocol (PDCP) of LTE also has sequence numbers, and the two layers of sequence numbers cause the following problems: increase the system complexity: the PDCP and RLC of the sender maintain SN respectively; the receiving part RLC completes sequencing and data recombination; after DU data is sent to a CU, the PDCP at the CU side needs to be sequenced again due to the diversity of the cable transmission quality; the multi-layer protocol head increases the overhead of air interface resources and reduces the transmission efficiency of the air interface resources; and multiple sequencing causes data delay increase, directly affects Round Trip Time (RTT) of data, and indirectly affects service quality.
In view of the above problems, no effective solution has been proposed in the related art.
