Patent ID: 8340153

Claim:
A wireless transmit/receive unit (WTRU) comprising: a receiver configured to receive in a first single symbol time interval a plurality of subcarriers; wherein a first group of subcarriers from the plurality of subcarriers includes information for the WTRU combined with an orthogonal sequence; wherein the first group of subcarriers includes information for a plurality of WTRUs; wherein the information for each of the plurality of WTRUs is combined with an orthogonal sequence and the orthogonal sequence for each of the plurality of WTRUs is different; wherein a second group of subcarriers from the plurality of subcarriers includes information for the WTRU not combined with an orthogonal sequence; wherein the receiver is further configured to recover the information for the WTRU from the first group of subcarriers and the receiver is further configured to recover the information for the WTRU from the second group of subcarriers; and wherein a third group of subcarriers from the plurality of subcarriers in the first single symbol time interval includes information for another WTRU that is not combined with an orthogonal sequence.
