Techniques for conserving power for communication between wireless devices

A device comprising:

• a modulator;
• a demodulator;
• and
• at least one processor, wherein the at least one processor is configured to:
• establish a transmit opportunity (TXOP) with a second device;
• send one or more data frames to the second device, wherein the one or more data frames comprise (i) a respective duration field comprising a duration of the TXOP remainder and (ii) a respective Quality of Service (QoS) control field, the respective QoS control field comprising a rendezvous offset;
• and
• determine a rendezvous time at which to wake up from power save mode based at least in part on the rendezvous time offset and the duration.

A method comprising:

• sending, by a first wireless device to a second wireless device, a first control frame to establish a transmit opportunity (TXOP) with the second wireless device, wherein a duration field associated with the first control frame comprises a rendezvous time at which the first wireless device and the second wireless device will wake up from respective power save modes;
• receiving, by the first wireless device, a second control frame from the second wireless device;
• sending, by the first wireless device to the second wireless device, a contention-free (CF)-end frame, the CF-end frame terminating the TXOP;
• and
• in response to sending the CF-end frame, entering, by the first wireless device, into the power save mode until the rendezvous time is reached.

One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by at least one processor, configure the at least one processor to perform operations comprising:

• sending one or more data frames to a wireless device;
• receiving, from the wireless device, a block acknowledgement (BACK) that at least a portion of the one or more data frames was received, wherein the BACK comprises a first indication in an RBUFCAP field of the BACK, wherein the first indication causes the at least one processor to not send one or more subsequent data frames;
• and
• in response to receiving the BACK, entering into a low power receive mode, wherein the at least one processor is configured not to receive data frames during the low power receive mode.

One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by at least one processor associated with a first device, configure the at least one processor to perform operations comprising:

• receiving, from a second device, a request a first control frame, to establish a transmit opportunity (TXOP) with the first device, wherein a duration field associated with the first control frame comprises a rendezvous time at which the first device and the second device will wake up from respective power save modes;
• sending a second control frame, the second control frame indicating to the second device that a TXOP has been established;
• receiving, from the second device, one or more data frames;
• receiving, from the second device, a contention-free (CF)-end frame, wherein the CF-end frame terminates the TXOP;
• and
• in response to receiving the CF-end frame, entering power save mode until the rendezvous time is reached.
