The Design And Implementaion Of RLC Protocol On The Side Of Enodeb Inside TD-Lte Protocol Stack Architecture

Firstly,based on understanding of GSM technology, we make the depth study of the36series of TD-LTE protocol of version R9, detailed design is made to LTE36.321,36.322and36.323protocol data between the function of each module and module interactionSecondly,we studied the LTE air interface protocol integrated network architecture of LTE,discussed the necessity of study of RLC layer in the air interface protocol,then we reflect the status and influence of RLC layer from the division of the air interface layer module,put forward to solve the communication solutions in adding L2the Config module and RLC Control module, it simplified the RLC layer system structure, let RLC layer protocol architecture simplely reflected, it is quite significance in improving the communication efficiency and ensuring the reliability of communication.The third,the most important part is protocol36.322,we analysis the way how to carry out processing when RLC layer receive the messages from the upper layer and RLC message’s format and size,even the other state of affairs.The manage ways when the message lost or receiveAt last,through the discussion and analysis of the detailed design of RLC layer protocol module, based on the flow chart of message transmission design,We put forward the RTL code scheme and compiled through and depoly the hardware simulator,then set a breakpoint on the input dat,make a conclusionby observing the output deals.After analyzing the results,we fully proves that the funcion in RLC layer of LTE protocol stack,provides research essential for the development and system software of embedded LTE protocol.
