Space division multiple access channelization in wireless communication systems
First Claim
Patent Images
1. A method for facilitating channelization in a wireless communication system, comprising:
- scheduling transmission to at least two terminals on overlapping frequency resources for an overlapping time period on different spatial resources; and
utilizing different code offsets for pilots sent to the at least two terminals, wherein the different code offsets correspond to different sub-trees.

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.
