(canceled)
A wireless communication unit configured for very high throughput (VHT) communication over a primary channel and a plurality of secondary channels, wherein the wireless communication unit comprising a processor and transceiver arranged to:
- monitor for traffic in a primary channel and a plurality of secondary channels;
- determine that one or more channels of the plurality of secondary channels is idle;
- select a contiguous available bandwidth from at least channel widths of 20 MHz, 40 MHz, 80 MHz, and 160 MHz;
- transmit a multichannel request to send (RTS) frame to a responder on the primary channel and one or more of the idle secondary channels, wherein the multichannel RTS frame is a single frame occupying the selected contiguous available bandwidth and indicates the selected available bandwidth;
- receive a multichannel clear to send (CTS) frame on the primary channel and at least one of the one or more of the secondary channels on which the multichannel RTS was transmitted;
- and
- transmit data using the available bandwidth indicated in the multichannel CTS frame.
A wireless communication station (STA) configured for very high throughput (VHT) communication over a primary channel and a plurality of secondary channels, the STA comprising physical layer (PHY) circuitry and processing elements to:
- monitor for traffic in a primary channel and a plurality of secondary channels;
- determine that one or more channels of the plurality of secondary channels is idle;
- select a contiguous available bandwidth from at least channel widths of 20 MHz, 40 MHz, 80 MHz, and 160 MHz;
- transmit a multichannel request to send (RTS) frame to a responder on the primary channel and one or more of the idle secondary channels, wherein the multichannel RTS frame is a single frame occupying the selected contiguous available bandwidth and indicates the selected available bandwidth;
- receive a multichannel clear to send (CTS) frame on the primary channel and at least one of the one or more of the secondary channels on which the multichannel RTS was transmitted;
- and
- transmit data using the available bandwidth indicated in the multichannel CTS frame.
A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors to perform operations for operating a communication station (STA) in a wireless network, the operation to configure the STA to:
- monitor for traffic in a primary channel and a plurality of secondary channels;
- determine that one or more channels of the plurality of secondary channels is idle;
- select a contiguous available bandwidth from at least channel widths of 20 MHz, 40 MHz, 80 MHz, and 160 MHz;
- transmit a multichannel request to send (RTS) frame to a responder on the primary channel and one or more of the idle secondary channels, wherein the multichannel RTS frame is a single frame occupying the selected contiguous available bandwidth and indicates the selected available bandwidth;
- receive a multichannel clear to send (CTS) frame on the primary channel and at least one of the one or more of the secondary channels on which the multichannel RTS was transmitted;
- and
- transmit data using the available bandwidth indicated in the multichannel CTS frame.
