Embodiment Construction

[0030] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

[0031] figure 2Shows the structure of a mobile communication system that transmits and receives data according to the RLP to which the present invention is applied.

[0032] refer to figure 2 , the physical layer processors 150 and 250 respectively connect the physical channels between the mobile station and the base station according to the IS-2000 technical specification, and send the RLP frames provided from the relevant RLP processors 130 and 230 to other parties via the connected physical channels and send the RLP frames received through the physical channel to the RLP processors 130 and 230 respectively. Multiplexing / demultiplexing controllers 140 and 240 are disposed between corresponding RL...

Abstract

A method for transmitting a plurality of data frames in a mobile telecommunications system is disclosed. Each data frame has a frame sequence number and a data block. The method comprises the steps of segmenting a data frame into a plurality of data segments for retransmission, assigning the frame sequence number to each of said data segment, and assigning respective sequence numbers to the data bytes of each data segment to distinguish the first and last bytes of said data segment.

Description

technical field [0001] The present invention relates generally to a CDMA (Code Division Multiple Access) mobile communication system, and more particularly to an apparatus and method for transmitting and receiving data according to a Radio Link Protocol (RLP) for efficient data transmission in a wireless environment. Background technique [0002] Generally, the CDMA mobile communication system has developed from the IS-95 standard mainly providing voice services to the CDMA-2000 standard providing high-speed data services as well as voice services. The CDMA-2000 standard can provide high-quality voice services, motion picture services and Internet search services. [0003] figure 1 Indicates a typical packet data service defined by CDMA-2000. exist figure 1 In , a mobile station (MS) includes a terminal equipment (TE) and a mobile terminal (MT). A base station is denoted by BS / MSC (Base Station / Mobile Switching Center), and an Interworking Function...
