Abstract: The present disclosure presents aspects for managing performance of a wireless network. For example, the aspects may include identifying a backhaul condition at a small cell in the wireless network wherein the backhaul condition is associated with one or more of a backhaul latency measurement, a backhaul error rate, or a backhaul jitter value at the small cell and triggering an action at the small cell in response to identifying the backhaul condition at the small cell, wherein triggering the action at the small cell includes modifying one or more resource management parameters at the small cell based on the backhaul condition. As such, performance of a wireless network may be managed.

Abstract: A timer parameter used for transitioning between radio protocol states is adapted based on a change of a handover parameter. For example, as a direct result of a change in a handover parameter such as time-to-trigger, offset, or hysteresis, an inactivity timer that is used for switching an access terminal from a connected state to an idle state may be adapted. As another example, as a direct result of a change in a handover parameter, a radio link failure (RLF) timer that is used for switching an access terminal to an RLF state may be adapted.

Abstract: Confusion associated with a physical layer identifier is detected and action taken to address this confusion. In some aspects, confusion detection involves determining whether signals such as beacons or pilots that are associated with the same physical layer identifier are also associated with different timing (e.g., different observed time difference (OTD) values). In some aspects, confusion detection involves determining whether an inordinate number of handover failures is associated with a particular physical layer identifier. In some aspects, the action taken upon detecting physical layer identifier confusion involves ensuring that an access terminal is not handed over to an access point that uses that physical layer identifier. In some aspects, the action taken upon detecting physical layer identifier confusion involves resolving the confusion.
