Abstract
Techniques to enable dynamic bandwidth management at the physical layer level while maintaining backwards compatibility in wireless systems is provided. Furthermore, techniques for reducing the occurrence of exposed nodes are provided. A transmitter may transmit a frame including an indication that a PHY layer sub-header defining a bandwidth associated with a channel is present. Furthermore, the transmitter may transmit a third frame after receiving a second frame from a receiver to indicate to legacy stations that the TXOP was successful.

1-25. (canceled)
An apparatus comprising:
- an interface;
- and
- circuitry coupled with the interface, the circuitry operable to execute one or more instructions that when executed cause the circuitry to:
- generate a protocol data unit to communicate wirelessly, the protocol data unit comprising a header and a first sub-header, the header comprising a bit in a field distinct from the first sub-header, wherein the bit indicates a presence of the first sub-header, and the first sub-header comprising an indication of a channel bandwidth to be used to communicate data;
- and
- cause wireless transmission of the protocol data unit.
A non-transitory computer-readable storage medium, comprising a plurality of instructions, that when executed, enable processing circuitry to:
- generate a protocol data unit to communicate wirelessly, the protocol data unit comprising a header and a first sub-header, the header comprising a bit in a field distinct from the first sub-header, wherein the bit indicates a presence of the first sub-header, and the first sub-header comprising an indication of a channel bandwidth to be used to communicate data;
- and
- cause wireless transmission of the protocol data unit.
A computer-implemented method, comprising:
- generating a protocol data unit to communicate wirelessly, the protocol data unit comprising a header and a first sub-header, the header comprising a bit in a field distinct from the first sub-header, wherein the bit indicates a presence of the first sub-header, and the first sub-header comprising an indication of a channel bandwidth to be used to communicate data;
- and
- causing wireless transmission of the protocol data unit.
