Abstract
A method is performed by a wireless device functioning as a beamformer station (STA) in a wireless network to perform a sounding procedure. The method includes wirelessly transmitting a null data packet (NDP) announcement frame in a first frequency band, the NDP announcement frame including a sounding dialog token field where bits B0 and B1 of the sounding dialog token field are set to binary ‘1’ to indicate the NDP announcement frame should be processed as an extremely high throughput (EHT) NDP announcement frame, and wirelessly transmitting an NDP frame in a second frequency band.
Claims20
A method performed by a wireless device functioning as a beamformer station (STA) in a wireless network to perform a sounding procedure, comprising:
- wirelessly transmitting a null data packet (NDP) announcement frame in a first frequency band, the NDP announcement frame including a sounding dialog token field where bits B0 and B1 of the sounding dialog token field are set to binary ‘1’ to indicate the NDP announcement frame should be processed as an extremely high throughput (EHT) NDP announcement frame;
- and
- wirelessly transmitting an NDP frame in a second frequency band.
A method performed by a wireless device functioning as a beamformer station (STA) in a wireless network to perform a sounding procedure, comprising:
- wirelessly transmitting a null data packet (NDP) announcement frame in a first frequency band;
- and
- wirelessly transmitting an NDP frame in a second frequency band different from the first frequency band in response to wirelessly transmitting the NDP announcement frame.
A wireless device to function as a beamformer station (STA) in a wireless network, comprising:
- a radio frequency transceiver;
- a memory device storing a set of instructions;
- and
- a processor coupled to the memory device, wherein the set of instructions when executed by the processor causes the beamformer STA to:
- <wirelessly transmit, via the radio frequency transceiver, a null data packet (NDP) announcement frame in a first frequency band, wherein the NDP announcement frame includes a sounding dialog token field where bits B0 and B1 of the sounding dialog token field are set to binary ‘1’ to indicate the NDP announcement frame should be processed as an extremely high throughput (EHT) NDP announcement frame;
- and
- wirelessly transmit, via the radio frequency transceiver, an NDP frame in a second frequency band.
