Abstract: Systems and methodologies are described that facilitate detecting impulsive interference of pilot signals in wireless communications networks and accounting for such interference in estimating data channels to decode the pilot signals. Portions of a received pilot signal can be compared to other portions to create correlated subsets of similar portions. The number of portions in a subset can indicate a high likelihood of non-interference, and portions that are not in the subsets can be disregarded or weighted less in estimating channels for decoding. In cases of ambiguous subsets or portions, one or more subsets/portions can each be used to estimate the channel and data can be decoded multiple times. The decoding that results in a higher decoding metric can be selected. Additionally, systems and methodologies for inserting pilot signals within data are described.

Abstract: Systems and methods are described that facilitate evaluating conditions of nodes (e.g., access points, access terminals, etc.) in a wireless communication environment to determine a level of disadvantage for a given node relative to other nodes. A first node may receive a resource utilization message (RxRUM) and may determine a level of disadvantage for a node that sent the RxRUM. The first node may then compare its own level of disadvantage to the sending node in order to permit a determination of an appropriate course of action in response to the RxRUM.

Abstract: Systems and methods are disclosed that facilitate wireless communication using resource utilization messages (RUMs), in accordance with various aspects. A RUM may be generated for a first node, such as an access point or an access terminal, to indicate that a first predetermined threshold has been met or exceeded. The RUM may be weighted to indicate a degree to which a second predetermined threshold has been exceeded. The first and/or second predetermined thresholds may be associated with various parameters associated with the node, such as latency, throughput, data rate, spectral efficiency, carrier-to-interference ratio, interference-over-thermal level, etc. The RUM may then be transmitted to one or more other nodes to indicate a level of disadvantage experienced by the first node.
