Claim Text:
1. A wireless transmit/receive unit (WTRU) comprising: circuitry configured to receive at least a first primary synchronization signal out of a plurality of primary synchronization signals; wherein each primary synchronization signal is received in an orthogonal frequency division multiple access (OFDMA) symbol within a transmission time interval; wherein the primary synchronization signals are received over a fixed number of subcarriers at a center of a system bandwidth; wherein the circuitry is further configured to receive the at least one first primary synchronization signal over the fixed number of subcarriers at a center of a transmission bandwidth for any of a plurality of different system bandwidths; and the circuitry is further configured, based on a received timing of the at least first primary synchronization signal, to receive system information in at least one OFDM symbol next in time to the OFDM symbol of a second primary synchronization signal out of the plurality of primary synchronization signals; wherein the received system information is received in the fixed number of subcarriers at the center of the system bandwidth; wherein the system information includes an indication of the system bandwidth and an indication of a number of transmission antennas of a base station, wherein the circuitry is further configured to process received data based on the number of transmission antennas of the base station.
