Abstract

TECHNIQUES FOR TRANSMITTING DATA USING A COMBINATION OF EXPLICIT CYCLIC DELAY AND IMPLICIT CYCLIC DELAY ARE DESCRIBED. A TRANSMITTER MAY PERFORM (612) FIRST PROCESSING FOR CYCLIC DELAY DIVERSITY (OR EXPLICIT CYCLIC DELAY PROCESSING) BASED ON A FIRST SET OF CYCLIC DELAY VALUES KNOWN TO A RECEIVER. THE TRANSMITTER MAY PERFORM PRECODING BASED ON A PRECODING MATRIX EITHER BEFORE OR AFTER THE EXPLICIT CYCLIC DELAY PROCESSING. THE TRANSMITTER MAY PERFORM (616) SECOND PROCESSING FOR CYCLIC DELAY DIVERSITY (OR IMPLICIT CYCLIC DELAY PROCESSING) BASED ON A SECOND SET OF CYCLIC DELAY VALUES UNKNOWN TO THE RECEIVER. THE TRANSMITTER MAY PERFORM BOTH EXPLICIT AND IMPLICIT CYCLIC DELAY PROCESSING FOR DATA AND MAY PERFORM ONLY IMPLICIT CYCLIC DELAY PROCESSING FOR PILOT. ONE ENTITY MAY SELECT THE FIRST SET OF CYCLIC DELAY VALUES AND INFORM THE OTHER ENTITY. THE TRANSMITTER MAY AUTONOMOUSLY SELECT THE SECOND SET OF CYCLIC DELAY VALUES WITHOUT INFORMING THE RECEIVER.
