A wireless access point (AP) configured to operate in accordance with both Wi-Fi and Long-Term Evolution (LTE-U) standards/protocols jointly schedules transmit opportunities for Wi-Fi and LTE-U frames. The AP assigns one of multiple, prioritized, Wi-Fi access categories to each Wi-Fi transmit frame based on a type of data in the transmit frame. The AP also assigns to each LTE-U transmit frame an LTE-U access category prioritized relative to the Wi-Fi access categories. The AP schedules Wi-Fi and LTE-U transmit opportunities for the Wi-Fi transmit frames and the LTE-U transmit frames, respectively, in the shared channel bandwidth based on the prioritized Wi-Fi and LTE-U access categories.
