Title:
APPARATUS, METHOD AND COMPUTER PROGRAM PRODUCT PROVIDING A TRANSPORT FORMAT THAT IS COMPATIBLE WITH ANOTHER TRANSPORT FORMAT THAT USES SPREADING CODES
Document Type and Number:
WIPO Patent Application WO2007091157
Kind Code:
A9
Abstract:
Either a first transport format or a second transport format is selected to transmit information corresponding to an input symbol sequence. The transport formats fit information into a timeslot having a predetermined duration. Based upon the selected transport format, either the information is created from the input symbol sequence using the first transport format or is created from the input symbol sequence using the second transport format. Creating the information for transmission using the first transport format applies a spreading code to the input symbol sequence. The information for transmission is transmitted in a selected timeslot having the predetermined duration. Creating and transmitting the information using the first transport format causes the transmitted information to occupy a first frequency band. Creating and transmitting the information using the second transport format causes the transmitted information to occupy a second frequency band that partially overlaps the first frequency band.
