摘要： Systems and methods are described that facilitate evaluating conditions of nodes (e.g., access points, access terminals, etc.) in a wireless communication environment having a plurality of carriers to determine a level of disadvantage for a given node relative to other nodes. The node may transmit a resource utilization message (RUM) that represents the level of disadvantage for the node and request other interference nodes to back off on one or more carriers.

摘要： Systems and methods are described that facilitate data communication in a wireless communication environment. According to various aspects, a node, such as an access point or an access terminal, may determine a number of channels over which it will transmit a communication signal. The node may then select channels based on whether the channels are available or unavailable, wherein available channels are preferentially selected over unavailable channels. The node may then transmit a signal over the at least one of the selected channels.

摘要： An authorization scheme limits the number of nodes that send out resource utilization messages. Here, a first node may determine whether a second node is allowed to transmit a resource utilization message, and send a message to the second node indicative of this determination. The second node may then determine whether to send out a resource utilization message based on the message from the first node and the quality of service associated with receive traffic at the second node. In some aspects, a node that is allowed to transmit a RUM may be identified based on whether the node is expected to be scheduled to use a given resource.

摘要： Contention for a resource in a multi-resource system is resolved by separately resolving contention for each resource. In some cases where two or more entities contending for a resource are associated with equal priorities, lexicographic ordering is used to resolve contention between these entities. In some cases where two or more entities contending for a resource are associated with equal priorities, a random probability-based scheme is used to resolve contention between these entities. Also, different types of schemes may be used to resolve contention for different resources.

摘要： 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.

摘要： Systems and methods are described that facilitate the determination and request of resources a node may wish to reserve. The resources include a plurality of carriers that are shared with other nodes. In an approach, the node determines a condition related to the plurality of carriers; creates an ordering of the plurality of resources; and transmits a resource utilization message (RUM) for one or more of the plurality of resources based on the ordering and the condition.

摘要： An adaptive scheme controls the transmission of interference management messages by wireless nodes. For example, the adaptive scheme may be used to determine whether and/or how to transmit resource utilization messages. Such a determination may be based on, for example, comparison of a quality of service threshold with a current quality of service level associated with received data. A quality of service threshold may be adapted based on the effect of previously transmitted resource utilization messages. A quality of service threshold for a given wireless node may be adapted based on the frequency at which the wireless node transmits resource utilization messages. A quality of service threshold for a given wireless node may be adapted based on information received from another wireless node. An adaptation scheme also may depend on the type of traffic received by a given wireless node. A quality of service threshold also may be adapted based on throughput information.
