AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
The patentability of claims 8-10 is confirmed.
Claims 1-7 and 11-21 were not reexamined.
8. An apparatus for providing flexible channel bandwidth in mobile radio communications, comprising:
at least one processor; and
at least one non-transitory computer-readable memory in electronic communication with the at least one processor, and instructions stored in the at least one memory, the instructions executable by the at least one processor for:
provisioning a set of Orthogonal Frequency Division Multiplexing (OFDM) subcarriers for mobile radio communications;
encoding data symbols with polyphase codes derived from a discrete Fourier transform to produce encoded data symbols; and
modulating the encoded data symbols onto the OFDM subcarriers to produce a superposition signal that resembles a single-carrier signal and has one of a plurality of different symbol durations;
wherein provisioning comprises selecting one of a plurality of different selectable subcarrier spacings, to provide for the one of the plurality of different symbol durations.
