Embodiment 2

[0140] Embodiment 2 cancels the encryption in the NodeB. The encryption is performed after the header is compressed in the core network gateway, and the corresponding decryption on the UE side is performed before the header is decompressed. Others are the same as the embodiment 1.

Embodiment 3

[0141] In Embodiment 3, the QoS-based multiplexing on the UTRAN plane is moved to the core network gateway for execution, and the others are the same as in Embodiment 1.

Embodiment 4

[0142] The protocol architecture of embodiment 4 is the same as that of embodiment 1, and the processing flow of the UTRAN plane downlink service described in this embodiment between each module is as follows Figure 9 shown. After the high-level retransmission and split cascading are interchanged, the high-level retransmission is to cache and retransmit the SDUs from the high-level. For the retransmitted data, the sending end only needs to maintain less split cascading information, and the corresponding receiving end reorganization is relatively Simple. Corresponding to the UTRAN plane, the processing flow of the UE plane downlink service among various modules described in this embodiment is as follows Figure 10 shown.

Abstract

The base station includes processing unit (PU) in physical layer, and MAC unit connected to each other. MAC unit includes modules: partition concatenation module partitions and cascades data; the transmission block generation module adds the head information on data after partitioning and cascading operation to generate the transmission block (TB) sent to physical layer. PU in physical layer addscheck bit on TB, and sends it to terminal. Terminal includes connected PU in physical layer, MAC unit, PDCP unit, and IP unit. PU in physical layer checks TB from the base station. In MAC unit, decomposition module removes data header to decompose TB; rearrangement module sorts the decomposed data; recombination module recombines sorted data. Parsing header of the recombined data, PDCP unit compresses data, and sends the compressed data to up layer. The invention makes better interaction between MAC layer and RLC layer, reduces unnecessary time delay, overhead, and filling operation.

Description

technical field [0001] The present invention relates to a wireless transmission system, in particular to a base station and terminal based on an evolution architecture in the wireless transmission system and a method for transmitting and receiving data thereof. Background technique [0002] UMTS adopts WCDMA wireless transmission technology on the air interface, which is divided into three protocol layers L1, L2 and L3 in R6, which correspond to the physical layer, data link layer and network layer of the OSI reference model respectively, and L2 is divided into It is Media Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP) and Broadcast / Multicast Control Protocol (BMC), and its protocol structure is as follows figure 1 shown. [0003] MAC is located above the physical layer of the UMTS Terrestrial Radio Access Network (UTRAN) air interface. It is a sublayer of the data link layer L2. It shields the characteristics of the physical transmi...
