Abstract: An electronic device that selectively provides a trigger frame is described. During operation, the electronic device may receive a frame from a recipient electronic device, where the frame includes information that specifies a maximum uplink multi-user transmit duration of the recipient electronic device. Moreover, the electronic device may selectively provide the trigger frame to the recipient electronic device that specifies an uplink OFDMA frame or an uplink MIMO frame associated with the recipient electronic device. The trigger frame may be selectively provided when a transmit time corresponding to the uplink OFDMA frame or the uplink MIMO frame is less than or equal to the maximum uplink multi-user transmit duration.

Abstract: An electronic device that includes several antennas, at least one of which can receive signals communicated using a first type of wireless communication and at least another of which can transmit signals using a second type of wireless communication. The electronic device enables a signal to be transmitted in an unrestricted or restricted manner based on a criticality of data to be included in the signal.
