Rate and antenna selection using single txop

A method, comprising:

• obtaining in a probing Wi-Fi device a transmit opportunity (TXOP) on a Wi-Fi channel;
• transmitting a first probe packet from the probing Wi-Fi device to a receiving Wi-Fi device during the TXOP with a first antenna, wherein the first probe packet is transmitted with a first transmission parameters set;
• receiving first feedback responsive to transmitting the first probe packet with the first antenna;
• transmitting a second probe packet from the probing Wi-Fi device to the receiving Wi-Fi device during the TXOP with the first antenna, wherein the second probe packet is transmitted with a second transmission parameters set;
• receiving second feedback responsive to transmitting the second probe packet with the first antenna;
• transmitting the second probe packet from the probing Wi-Fi device to the receiving Wi-Fi device during the TXOP with a second antenna, wherein the second probe packet is transmitted with the second transmission parameters set;
• receiving third feedback responsive to transmitting the second probe packet with the second antenna;
• and
• setting, by the probing Wi-Fi device, one or more transmission parameters within a transmission parameters set based at least in part on the first feedback, the second feedback, or the third feedback.

A system, comprising:

• a memory storing instructions in a probing Wi-Fi device;
• and
• a processor coupled to a Wi-Fi transmitter and a Wi-Fi receiver in the probing Wi-Fi device, the Wi-Fi transmitter and the Wi-Fi receiver configured to communicate via a Wi-Fi channel, the processor configured to execute the instructions stored in the memory to:
• obtain a transmit opportunity (TXOP) on a Wi-Fi channel;
• transmit, by the Wi-Fi transmitter, a probe packet to a receiving Wi-Fi device during the TXOP with a first antenna, wherein the probe packet is transmitted with a transmission parameter within a transmission parameters set;
• receive first feedback at the Wi-Fi receiver responsive to transmitting the probe packet with the first antenna;
• transmit, by the Wi-Fi transmitter, the probe packet to the receiving Wi-Fi device during the TXOP with a second antenna, wherein the probe packet is transmitted with the transmission parameter within the transmission parameters set;
• receive second feedback at the Wi-Fi receiver responsive to transmitting the probe packet with the second antenna;
• and
• set, by the probing Wi-Fi device, the transmission parameter within the transmission parameters set and a selected antenna based at least in part on the first feedback or the second feedback.
