Embodiment Construction

[0030] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0031] It should be noted that the terms "first" and "second" in the description and claims of the present invention and the above drawings are used to distinguish similar objects, but not necessarily used to describe a specific sequence or sequence.

[0032] In order to reduce the transmission requirements on the fronthaul interface between the BBU and the RRU in the related art, multiple fronthaul interfaces can be introduced in addition to the CPRI interface, and different fronthaul interfaces correspond to different user plane function divisions of the BBU and RRU. Since the repartitioned RRU may also include some baseband functions, the repartitioned BBU and RRU are respectively named as a centr...

Abstract

The invention provides a data transmission method and device. The method comprises the following steps: confirming priority information of received data; filling the priority information into a grouped data aggregation protocol PDCP frame used for loading data; and sending the PDCP frame filled with the priority information to a far-end processing unit, wherein the far-end processing unit comprises more than two wireless loading RBs for sending data and different priority data are sent on different RBs. According to the invention, the problem that the related technique cannot adapt to mass flow data processing can be solved and the purposes of performing grading transmission on the mass flow data and increasing the data transmission rate can be achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data transmission method and device. Background technique [0002] With the continuous evolution of wireless communication technology and protocol standards, the mobile packet service has undergone tremendous development, and the data throughput capability of a single terminal has been continuously improved. Taking the Long Term Evolution (LTE for short) system as an example, it can support data transmission with a maximum downlink rate of 100 Mbps within a 20M bandwidth; in the subsequent LTE enhanced system and its subsequent 5G system, the data transmission rate will be further improved. It can even reach tens of Gbps. [0003] The expansive growth of terminal data traffic has brought enormous pressure and challenges to mobile network service capabilities and deployment strategies. On the one hand, operators need to enhance existing network deployment and communication t...
