Problems solved by technology

For example, from the perspective of power consumption, the power consumption pressure of single-baseband boards is more severe, and the closer to the upper limit of processing capacity, the faster the power consumption increases; from the perspective of cost performance, the choice of top-end chips faces higher costs and lower cost performance , which leads to simply improving the processing performance of the hardware chip is not a good choice

Embodiment Construction

[0048] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] Currently, the received gNB baseband service data needs to be submitted to the application layer (including the driver protocol stack) for processing. The existing implementation submission process is to transfer the data from the huge page memory pool to the shared memory by copying, and the reverse also needs to transfer th...

Abstract

Embodiments of the present invention provide a data transmission method and device, wherein the data transmission method includes: acquiring an applied data area header pointer of a memory cache MBUF, and encapsulating baseband board data in the MBUF according to the data area header pointer in; send the data area header pointer to the network adaptation layer as the first data pointer, so that the network adaptation layer modifies the data pointed to by the first data pointer, and modifies the data obtained after the data modification. The second data pointer is sent to the data plane development kit DPDK. The embodiments of the present invention improve the data transmission performance of the baseband board.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a data transmission method and device. Background technique [0002] With the development of the 5th generation mobile networks (5G) becoming more and more mature, the requirements for the service processing capability of a New Radio (New Radio, NR) base station in a multi-user multi-stream scenario are also gradually increasing. In this case, under the existing hardware platform, improving the software processing capability to adapt to business development becomes an important choice. [0003] At present, according to the existing 5G NR (gNB) base station standard, the general processor of the base station board needs to realize the pressure of three 100M NR cells in a single processor. For example, from the perspective of power consumption, the power consumption pressure of a single baseband board is more severe, and the closer to the upper limit of proce...
