Abstract

The invention provides a decoder device of Time Division Synchronous Code Division Multiple Access system enhanced uplink physical channel. The device includes: a first determining unit used for determining a transmitted data type and a transmitted resource multiplex way in current transmission interval, a second determining unit used for determining a transport block length and a modulation way of a enhanced uplink business data according to a resource multiplex situation and a authorized power, a third determining unit used for determining a physical layer control channel parameter of current transmission according to the determined business data and resource multiplexing way, and a fourth determining unit used for determining a resource count used by the user device according to a multiplexing instruct of the physical layer control parameter, and obtaining a modulation way and a transmission block length information of the service data by combining with the enhanced transmission format assemble instruct and carrying out a decoder and a modulation. Therefore, the invention avoids a cache of the channel data without increase of channel burden, and realizes a synchronous decoder of the channel and enhances a receiving efficiency of the channel.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more particularly relates to a decoding device for enhanced uplink physical channel of a time division synchronous code division multiple access system. Background technique [0002] In March 2006, the 3rd Generation Partnership Project (3rd Generation Partnership Project, hereinafter referred to as 3GPP) passed the project approval application for the time division synchronous code division multiple access (TD-SCDMA) system enhanced uplink. The enhanced uplink is generally called High Speed ​​Uplink Packet Access (High Speed ​​Uplink Packet Access, hereinafter referred to as HSUPA), and aims to improve the efficiency of the uplink through advanced technologies. [0003] A new transmission channel is added in HSUPA, that is, an Enhanced Uplink Dedicated Transport Channel (E-DCH), on which enhanced uplink service data is carried, and a transmission time interval (TTI) of...
