Patent ID: 8532065

Claim:
A mobile station comprising: at least one antenna; a transmitter operably coupled to said antenna to transmit over an uplink space time block codes modulated according to a Single Carrier-Frequency Division Multiple Access (SC-FDMA) modulation scheme, wherein the transmitter transmits according to a predetermined diversity scheme on the same Time-Frequency resources which are used by another mobile station, wherein the transmitter is able to transmit said space time block codes according to said diversity scheme by assigning each SC-FDMA symbol to a different sub carrier frequency, and transmitting a first SC-FDMA symbol at a first frequency and a second SC-FDMA symbol at a second frequency, the first frequency including a first sub-carrier frequency and the second frequency including a second sub-carrier frequency; and a receiver to receive over a downlink space time block codes which are modulated according to an Orthogonal Frequency Division Multiplexing (OFDM) modulation scheme.
