Embodiment Construction

[0034] (1) Data transmission process of LTE system

[0035] In the LTE system, the MAC (Media Access Control, Media Access Control) layer entity of the sending end node is responsible for assembling the data to be sent received from the upper layer into TB (transport block), and then handing the TB block to the physical layer, which is determined by After the physical layer is processed by encoding and modulation, it is sent to the receiving end node through the air interface. The physical layer entity of the receiving end node demodulates and decodes the received data, and submits the TB obtained after demodulation and decoding to the MAC layer, and the MAC layer entity demultiplexes the TB The data is submitted to the corresponding high-level entity for processing.

[0036] Specifically, the transmission of TBs can be managed in the form of processes, and in order to improve the reliability of data transmission, the LTE system adopts the HARQ mechanism, and each TB can corr...

Abstract

The invention discloses a data transmission method and equipment. The method comprises: a piece of network access equipment confirms a terminal type according to information of the terminal, confirms a data transmission mode corresponding to the terminal according to the terminal type and conducts data transmission with the terminal according to the data transmission mode. In the embodiment of the invention, the network access equipment can support low cost and low processing complex degree M2M terminal with lower performance than the present UE by confirming the terminal types with different processing performances and conducting data transmission terminals with different processing performances with by different data transmission modes to promote the wide application of M2M service.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and equipment. Background technique [0002] As a new type of communication concept, M2M (Machine-to-machine) communication aims to organically combine various types of communication technologies (such as: machine-to-machine communication, machine control communication, human-computer interaction communication, Mobile Internet communication, etc.), thus promoting the development of social production and lifestyle. Among them, the current mobile communication network is designed for communication between people (such as: the determination of network capacity, etc.), if you want to use the current mobile communication network to support M2M communication, you need to make a The mechanism of the communication system is optimized so as to better realize the M2M communication under the condition that the traditional human-to-human communicati...
