Title:
A METHOD FOR ASSIGNING AN AUTOMATIC REPEAT REQUEST ACKNOWLEDGEMENT INDICATOR CHANNEL IN A TIME DIVISION-SYNCHRONOUS CODE DIVISION MULTIPLE ACCESS (TD-SCDMA ) SYSTEM
Document Type and Number:
WIPO Patent Application WO/2008/022503
Kind Code:
A1
Abstract:
A method for realizing an automatic repeat request acknowledgement indicator channel (E-HICH ) in a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system. Said method comprises the following steps: a system generates sequence codes which are used for firstly spreading (101); the system selects corresponding sequence codes for the data determined by a linking layer, and spreads them firstly (101); the system modulates and sums the data which is spread firstly (103, 104), and spreads secondly and scrambles the summed data (105); the system arranges the data which is spread secondly and scrambled according to a defined structure of time intervals for the automatic repeat request acknowledgement indicator channel (106). Said method could ensure the correctly receiving of information and save the resources of downlink channel.
