Transmission format indication and feedback in multi-carrier wireless communication systems

One or more computer-readable media having one or more computer-readable media having computer-readable instructions stored thereon that, upon execution by a processor, cause the processor to specify a transmission mode for a communication signal transmitted between a first device and a second device, the instructions configured to:

• select a transmission mode subset from a plurality of subsets defined for transmission of the signal having a plurality of signal portions, wherein each of the plurality of subsets includes a plurality of transmission modes for the signal;
• select a signal portion transmission mode from the plurality of transmission modes of the selected transmission mode subset for each of the plurality of signal portions;
• define semantic bits, the semantic bits including a plurality of bits that indicate the selected transmission mode subset;
• and
• define an indicator bit for each of the plurality of signal portions, the indicator bit indicating the selected signal portion transmission mode for the respective signal portion;
• wherein the semantic bits and the indicator bit for each of the plurality of signal portions are included in a transmission from a first device to a second device to specify a transmission mode for each of the plurality of signal portions of the signal.
