Multi-partition radio frames

A non-transitory computer-readable medium having instructions stored thereon that are executable by an electronic device to perform operations comprising:

• receiving a frame of broadcast wireless data that includes:
• a plurality of partitions that each include multiple orthogonal frequency-division multiplexing (OFDM) symbols, wherein different ones of the partitions have different frequency transform sizes;
• and
• partition data that indicates the frequency transform sizes for the ones of the partitions, wherein a first one of the plurality of partitions has a first frequency transform size that is adapted for decoding by mobile devices moving at velocities up to a first maximum velocity and wherein a second one of the plurality of partitions has a second frequency transform size that is adapted for decoding by mobile devices that are moving at velocities up to a second, different maximum velocity;
• selecting, based on the partition data, one or more but not all of the plurality of partitions;
• and
• decoding the selected one or more partitions to determine data represented by the OFDM symbols in the selected one or more partitions.

An apparatus, comprising one or more processors and configured to:

• generate a payload region for a frame of wireless data, wherein the payload region includes a plurality of partitions that each include multiple orthogonal frequency-division multiplexing (OFDM) symbols, wherein different ones of the partitions have different frequency transform sizes for the OFDM symbols in the ones of the partitions;
• wherein a first one of the plurality of partitions has a first Fast Fourier Transform (FFT) size that is adapted for decoding by mobile devices moving at velocities up to a first maximum velocity and wherein a second one of the plurality of partitions has a second FFT size that is adapted for decoding by mobile devices that are moving at velocities up to a second, different maximum velocity;
• and
• transmit the generated payload region.

A method, comprising:

• receiving or generating, by a wireless base station, a payload region for a frame of wireless data, wherein the payload region includes a plurality of partitions that each include multiple orthogonal frequency-division multiplexing (OFDM) symbols, wherein different ones of the partitions have different frequency transform sizes for the OFDM symbols in the ones of the partitions;
• wherein a first one of the plurality of partitions has a first Fast Fourier Transform (FFT) size that is adapted for decoding by mobile devices moving at velocities in a particular range of velocities and wherein a second one of the plurality of partitions has a second FFT size that is adapted for decoding by mobile devices that are moving at velocities in a second, different range of velocities;
• and
• broadcasting, by the wireless base station, the frame of wireless data including the payload region.
