Abstract

This invention relates to a down frame protocol data shared transmit device and a method in the WCDMA system, in which, the method includes a frame protocol data buffer-storage connected with digital signal processor interface and a frame protocol data read circuit, used in buffer-storing down frame protocol data, accessed by the digital signal processor and the frame protocol data read circuit, a frame protocol data read circuit connected with the frame protocol data buffer and at least one parallel and serial transmit circuit responding the request of the transmit circuit and arraying and reading out related data from the buffer-storage to be transferred to transmit circuit and at least one parallel-serial transmit circuit for converting the parallel byte data sent by the frame protocol data read circuit to serial data to be sent to the coder.

Description

Technical field [0001] The invention relates to the technical field of code division multiple access communication, in particular to a wideband code division multiple access (WCDMA) system downlink frame protocol data sharing storage and forwarding device and method. Background technique [0002] The standard protocols 3GPP TS 25.212 and 25.427 are technologies such as WCDMA that specify processing procedures and data formats, but they have not yet been implemented. In a wideband code division multiple access (WCDMA) system in the prior art, the radio base station controller interface (NODEB) downlink system needs to receive frame protocol data packets from the radio base station interface (Iub), and perform channel coding and modulation. Since a NODEB supports a large number of downlink channels, the frame protocol data volume is very large, and the efficiency of buffering and forwarding of frame protocol data affects the processing performance of the NODEB downlink channel. The...
