Operation with bandwidth-limited devices in a wireless network

A wireless communication device for communicating in a wireless local area network (WLAN) that utilizes a communication channel having a plurality of component channels, the plurality of component channels including i) at least one primary component channel in which an access point transmits management frames including beacon frames, and ii) one or more non-primary component channels, the wireless communication device comprising:

• a wireless network interface device that is configured to operate with a maximum bandwidth that is less than a full bandwidth of the communication channel, wherein the wireless network interface device comprises one or more integrated circuit (IC) devices configured to:
• negotiate a target wake time (TWT) period with the access point, including negotiating a particular non-primary component channel among the one or more non-primary component channels in which the bandwidth-limited client station is expected to operate during the TWT period,
• operate the wireless network interface device in the particular non-primary component channel at least during the TWT period,
• receive a first legacy packet from the access point in the particular non-primary component channel, the first legacy packet including a beacon frame, the first legacy packet from among a plurality of legacy packets transmitted by the access point simultaneously in respective component channels, the plurality of legacy packets including respective duplicates of the beacon frame,
• receive a trigger frame from the access point in a second legacy packet in the particular non-primary component channel during the TWT period, the trigger frame configured to prompt the bandwidth-limited client station to transmit an uplink transmission in the particular non-primary component channel, and
• control the wireless network interface device to transmit the uplink transmission in the particular non-primary component channel in response to the trigger frame.
