Enhanced trigger frame based discovery for a neighbor awareness network

When a first node cannot hear a second node, the second node is “hidden” to the first node. In response to receiving a trigger frame, the two nodes may inadvertently transmit response frames at approximately the same time. The response frames may collide with each other, thereby causing delays in node discovery in a NAN. Provided herein are methods, apparatuses, and computer program products for reducing collisions in wireless communication. In some configurations, nodes may receive trigger frames that indicate a reduction in the rate that response frames are transmitted when traffic load conditions are high. In some configurations, nodes located in different coverage areas (e.g., a “hidden area” and a “non-hidden area”) may transmit response frames at different times. In some configurations, the nodes may refrain from transmitting their response frames upon hearing that another node having a higher serving preference rank is transmitting.

GATE DRIVE UNDER-VOLTAGE DETECTION

Gate drive faults are detected for an inverter which comprises a phase switch having an insulated gate, such as an IGBT. A complementary transistor pair is adapted to receive a supply voltage and a pulse-width modulated (PWM) signal to alternately charge and discharge the insulated gate. A comparator compares the voltage at the insulated gate with a reference voltage representing a gate drive fault to generate a first logic signal. A latch samples the first logic signal when the PWM signal has a value corresponding to charging the insulated gate. A logic circuit inhibits charging of the insulated gate when the latched logic signal indicates the gate drive fault. An insulated gate voltage less than the reference voltage is indicative of an under-voltage fault as well as other device failures of the IGBT or the complementary transistors.

Methods and apparatuses are provided for mitigating interference among access points, and/or devices communicating therewith, in unplanned network deployments. Based on determining that one or more served devices potentially interfere with one or more access points, an inter-frequency handover (IFHO) threshold or data rate can be adjusted for the device to cause IFHO or reduce occurrence of interference, and/or a coverage area can be modified so the device can communicate with one or more other access points to mitigate potential interference. Based on determining interference from one or more devices served by other access points, an access point can switch operating modes to a hybrid or open access point to allow the one or more devices to handover to the access point, and/or can boost downlink transmit power to cause the one or more devices to perform IFHO from the other access points to mitigate potential interference. 1. A method for mitigating interference in a wireless network , comprising:operating in a closed access mode allowing communications with member devices;detecting interference from one or more non-member devices served by one or more access points; andswitching to a hybrid or open access mode to allow communications with the one or more non-member devices based on the detected interference.2.
