Transmission rules within a TXOP for wider bandwidth operation

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a very-high throughput (VHT) station (STA), the instructions to configure the one or more processors to:

• decode a non-high-throughput (non-HT) duplicate Physical Layer Convergence Protocol (PLCP) Protocol Data Unit (PPDU) or non-HT PPDU, the non-HT duplicate PPDU or the non-HT PPDU comprising a request to send (RTS) frame, the RTS frame comprising an address of the VHT STA, an indication of static or dynamic bandwidth operation, and an indication of a channel bandwidth;
• in response to the RTS frame indicating the static bandwidth operation, a network allocation vector (NAV) indicating idle, and a clear channel assessment (CCA) of all secondary channels in the channel bandwidth being idle for a priority interframe space (PIFS) before receiving the RTS frame, encode a clear-to-send (CTS) frame to comprise a channel bandwidth field set to a value indicating the channel bandwidth indicated by the RTS frame, and generate signaling to cause the VHT STA to transmit the CTS frame;
• and
• in response to the RTS frame indicating the dynamic bandwidth operation and the NAV indicating idle, select one channel bandwidth where the CCA of all secondary channels of the one channel bandwidth is idle for a PIFS before receiving the RTS frame, wherein the one channel bandwidth is equal to or less than the channel bandwidth indicated by the RTS frame, and encode the CTS frame to comprise the channel bandwidth field set to a value indicating the one channel bandwidth and generate signaling to cause the VHT STA to transmit the CTS frame.

A method performed by an apparatus of a very-high throughput (VHT) station (STA), the method comprising:

• decoding a non-high-throughput (non-HT) duplicate Physical Layer Convergence Protocol (PLCP) Protocol Data Unit (PPDU) or non-HT PPDU, the non-HT duplicate PPDU or the non-HT PPDU comprising a request to send (RTS) frame, the RTS frame comprising an address of the VHT STA, an indication of static or dynamic bandwidth operation, and an indication of a channel bandwidth;
• in response to the RTS frame indicating the static bandwidth operation, a network allocation vector (NAV) indicating idle, and a clear channel assessment (CCA) of all secondary channels in the channel bandwidth being idle for a priority interframe space (PIFS) before receiving the RTS frame, encoding a clear-to-send (CTS) frame to comprise a channel bandwidth field set to a value indicating the channel bandwidth indicated by the RTS frame, and generating signaling to cause the VHT STA to transmit the CTS frame;
• and
• in response to the RTS frame indicating the dynamic bandwidth operation and the NAV indicating idle, selecting one channel bandwidth where the CCA of all secondary channels of the one channel bandwidth is idle for a PIFS before receiving the RTS frame, wherein the one channel bandwidth is equal to or less than the channel bandwidth indicated by the RTS frame, and encode the CTS frame to comprise the channel bandwidth field set to a value indicating the one channel bandwidth and generate signaling to cause the VHT STA to transmit the CTS frame.

An apparatus of an access point (AP), the apparatus comprising:

• a memory;
• and, circuitry coupled to the memory, the circuitry configured to:
• encode a request-to-send (RTS) frame in a non-high-throughput (non-HT) physical (PHY) Layer Convergence Procedure (PLCP) protocol data unit (PPDU) or non-HT duplicate PPDU, the RTS frame comprising an address of a station (STA), and wherein the RTF frame comprises an indication of a static bandwidth or a dynamic bandwidth and an indication of a channel bandwidth;
• and
• generate signaling to cause the AP to transmit the non-HT PPDU or non-UT duplicate PPDU within the channel width.
