SYSTEMS AND METHODS FOR OPEN-LOOP SPATIAL MULTIPLEXING SCHEMES FOR RADIO ACCESS VIRTUALIZATION

摘要

System and method embodiments are provided for open-loop spatial multiplexing for radio access virtualization. In an embodiment, a system includes a plurality of antenna ports and a processor coupled to the plurality of antenna ports and configured to spread a spreading sequence over at least a portion of the plurality of antenna ports in a spatial domain, wherein the processor is configured to cause the antenna ports to transmit multiple spreading sequences simultaneously by sequence superposition.
