Implicit full duplex communication in 802.11ax wireless networks

An apparatus comprising:

• one or more wireless transceivers;
• one or more modems coupled to the wireless transceivers;
• a controller configured to cause the apparatus to perform operations including:
• sending to a first wireless device a trigger frame that causes the first wireless device to send an uplink transmission to the apparatus after a first time interval;
• waiting a second time interval after the first wireless device is expected to begin sending the uplink transmission;
• receiving the uplink transmission from the first wireless device;
• and
• after the second time interval, and while receiving the uplink transmission from the first wireless device, sending to a second wireless device a downlink transmission that overlaps at least partially in frequency and time with the uplink transmission from the first wireless device.

One or more non-transitory computer readable storage media encoded with instructions that, when executed by a processor, cause the processor to perform operations on behalf of a wireless access point device that is full-duplex capable and that serves wireless communication for at least a first wireless client device and a second wireless client device, the operations including:

• sending to the first wireless client device a trigger frame that causes the first wireless client device to send an uplink transmission to the wireless access point device after a first time interval;
• waiting a second time interval after the first wireless client device is expected to begin sending the uplink transmission;
• receiving the uplink transmission from the first wireless client device;
• and
• after the second time interval, and while receiving the uplink transmission from the first wireless client device, sending to the second wireless client device a downlink transmission that overlaps at least partially in frequency and time with the uplink transmission from the first wireless client device.
