Abstract

Space division multiple access channelization is provided that includes scheduling transmission for two or more terminals and utilizing different code offsets that correspond to different sub-trees. The transmissions can be scheduled on overlapping frequency resources for overlapping time periods on different spatial resources. The pilot code offsets provide different pilot signatures so that the pilot transmissions do not overlap. The overlapping frequency resources can partially overlap or completely overlap.

Description

[0001] This application claims the benefit of US Provisional Application No. 60 / 828,821, filed October 10, 2006, entitled "SPACE DIVISIONMULTIPLE ACCESS CHANNELIZATION IN WIRELESS COMMUNICATION SYSTEMS." The entire content of this application is hereby incorporated by reference into the present application. technical field [0002] The following description relates to wireless communication, in particular to channelization of space division multiple access in a wireless communication system, and the like. Background technique [0003] Wireless communication systems have become a popular way for most people around the world to communicate. Wireless communication devices are becoming smaller and more powerful day by day to meet users' demands and to increase portability and convenience. The increase in processing power of mobile devices such as cellular phones has increased the demands placed on wireless network transmission systems. Such wireless network transmission system...
