Abstract

The present invention provides a decoding method for an enhanced uplink physical channel of a time division synchronous code division multiple access system. The method includes the following steps: when an enhanced uplink transmission time interval arrives, the user equipment determines the data type and resources transmitted in the current transmission time interval Multiplexing mode: the user equipment determines the transmission block length and modulation mode of the enhanced uplink service data according to the resource multiplexing situation and authorized power; the user equipment determines the physical layer control channel for this transmission according to the determined service data and resource multiplexing mode parameters; and the base station determines the total number of resources used by the user equipment according to the multiplexing indication in the physical layer control parameters, and combines the enhanced transmission format combination indication to obtain the modulation mode and transmission block length information of the service data part, and then demodulates and decodes . Therefore, without increasing the channel load, the buffering of channel data is avoided, the synchronous demodulation of the channel is realized, and the receiving efficiency of the channel is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, relates to a decoding method of an enhanced uplink physical channel in 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 technology. [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) o...
