Embodiment Construction

[0101] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0102] For the purpose of saving packet header overhead, the present invention performs cascading operations at the ARQ entity, but does not perform cascading operations during retransmission, and the size of the ARQ PDU generated by the ARQ entity is determined according to the air interface and scheduler instructions, so as to minimize Header overhead during multiplexing.

[0103] In order to better illustrate the solutions of the present invention, the following will be described in combination with preferred implementation modes of the present invention.

[0104] The flow of data processing supporting the LTE air interface protocol structure according to the first preferred embodiment of the present invention is shown in FIG. 22 .

[0105] First enter step 1...

Abstract

The invention relates to mobile communication field, and discloses a data processing method of long evolutive network, and improves the efficiency of processing the data pack in the LTE network L2. In the invention, the ARQ function is split to generate the ARQ PDU according to the interface state, and reduces the ferrule cost of logic channel identifier.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to the evolution technology of the third generation mobile communication (The Third Generation, referred to as "3G"). Background technique [0002] The Universal Mobile Telecommunications System ("UMTS") is a complete third-generation mobile communication (The Third Generation, "3G") mobile communication technical standard, defining a series of technical specifications including the air interface. and agreement. [0003] Functionally, the UMTS network side can be divided into a UMTS Terrestrial Radio Access Network (UMTS Terrestrial Radio Access Network, "UTRAN" for short) and a core network (Core Network, "CN" for short). Among them, UTRAN is used to handle all wireless related functions, and CN is used to handle all voice calls and data connections in the UMTS system and the exchange and routing of external networks. Among them, the system structure of UMTS is shown i...
