Claim 7:
8. A wireless transmit/receive unit (WTRU), the WTRU comprising:
a processor and a transceiver which are configured to:
determine an operating band of the WTRU from among a plurality of frequency bands within a system bandwidth of a wireless system, wherein each of the plurality of frequency bands is associated with a respective set of signal structures;
determine the set of signal structures that is associated with the determined operating band, wherein the set of signal structures includes (1) a first signal structure including a first subcarrier spacing for a synchronization signal (SS) and (2) a second signal structure including a second subcarrier spacing for the SS, and the first subcarrier spacing is different than the second subcarrier spacing,
receive the SS using a set of resources having one of the one of the first subcarrier spacing of the first signal structure or the second subcarrier spacing of the second signal structure,
receive and decode a first physical channel transmission, which includes a master information block (MIB), using a set of resources having a same subcarrier spacing as the set of resources used to receive the SS, wherein the MIB includes information indicating a third signal structure of a second physical channel transmission,
receive and decode the second physical channel transmission, which includes a system information block (SIB), using a set of resources having a third subcarrier spacing for the second physical channel transmission, wherein the third subcarrier spacing is based on the third signal structure and the SIB includes information indicating a fourth signal structure of a physical random access channel transmission, and
send the physical random access channel transmission using a set of resources having a fourth subcarrier spacing for the physical random access channel, wherein the fourth subcarrier spacing is based on the fourth signal structure.
