Embodiment Construction

[0028] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0029] image 3 It is a flow chart of the decoding method of the enhanced physical channel according to the present invention. like image 3 As shown, the decoding method of the enhanced physical channel includes the following steps:

[0030] (1) Step S301, when an enhanced uplink transmission time interval arrives, the user equipment determines the data type and resource multiplexing mode transmitted in the current transmission time interval.

[0031] Among them, the following steps are also included: if there are non-scheduled resources or scheduled resources in the transmission time interval, the user equipment selects corresponding service data for transmission ...

Abstract

The invention provides a decoding method of enhancing an uplink physical channel by a time division synchronous code division multiple access system. The decoding method includes the following steps: step S301, when an enhanced uplink transmission time interval comes, user equipment determines a data type and a resource multiplexing mode transmitted in the current transmission time interval; step S302, the user equipment determines the length of a transmission block and the modulation type of the enhanced uplink service data; step S303, the user equipment determines the physical layer control channel parameters of the current transmission; step S304, a base station determines the total number of resources used by the user equipment; and step S305, the base station combines enhanced transmission format combined indication to obtain part of the length of a transmission block and the modulation type of service data and then carries out demodulation and decoding; wherein, the data type includes a dispatching service data type and a non-dispatching service data type. In this way, under the condition of no increment of channel load, the invention can avoid the caching of channel data, realize the synchronous demodulation of the channel and improve the receiving efficiency of the channel.

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. 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 the E-DCH is 5 ms. In one TTI, one E-DCH transport channel cons...
