Patent ID: 7715460

Claim:
A wireless transmit/receive unit (WTRU) configured to perform hybrid orthogonal frequency division multiple access (OFDMA) communications comprising: a receiver configured to receive hybrid OFDMA symbols, where the hybrid OFDMA symbols include multi-user spread input data on a first group of subcarriers and non-spread input data on a second group of subcarriers; the receiver configured to process the received hybrid OFDMA symbols to recover single-user spread input data from the multi-user spread input data on the first group of subcarriers and the non-spread input data from the second group of subcarriers; the receiver comprising: a spread OFDMA subassembly configured to recover single-user input data from the multi-user spread input data by performing code domain user separation; and a non-spread OFDMA subassembly configured to recover second input data from the non-spread input data.
