Abstract: An adaptive scheme controls the transmission of interference management messages by wireless nodes. The adaptive scheme is used to determine whether and/or how to transmit resource utilization messages. Such a determination is based on comparison of a quality of service threshold with a current quality of service level associated with received data (206). A quality of service threshold may be adapted based on the effect of previously transmitted resource utilization messages (214). 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 is also adapted based on throughput information (2.14).

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: A method and apparatus for channel estimation in a system employing differing transmission protocols as broadcast/multicast and unicast protocols. The number of pilot tones used for broadcast transmission is greater than the number of pilot tones used for a unicast transmission. The channel estimation may be significantly degraded when a symbol from a broadcast transmission slot is adjacent to a symbol from a unicast transmission slot, since the pilots of the adjacent slots are used for the channel estimate. Therefore, it is determined whether a first time slot of one transmission protocol (multicast slot) is adjacent to a second time slot of another transmission protocol (unicast slot), and if a first symbol of the unicast slot. The pilot power or/and the number of the pilot sub-carriers is/are increased for the edge symbol of the multicast slot for purposes of channel estimation using the edge symbol.

Abstract: In a cellular wireless communication system, peer-to-peer (P2P) links between mobile devices are implemented, and controlled using an aggregate utility metric for a group of P2P and cellular links. A mobile node participating in a P2P link, or an eNB, may periodically broadcast an activity level indicator indicating a resource-dependent activity level of the link. The node may control the activity level in response to utility metrics received from members of neighboring P2P links to maximize an aggregate utility of the link and the neighboring P2P links sharing at least a subset of resources of a common frequency spectrum. Formation or termination of P2P links may be controlled in response to comparing a calculated achievable utility value to a current utility value of a link, and taking action calculated to maximize the aggregate utility value.

Abstract: Techniques for selecting and processing signals from different stations in a wireless network are described. A destination station may receive a direct signal from a source station and at least one relay signal from at least one relay station. The destination station may determine metrics for the source and relay stations, e.g., based on pilots received from these stations. The destination station may select at least one signal to process from among the direct and relay signals based on the metrics for the source and relay stations. The destination station may select the direct signal if the metric for the source station exceeds a threshold. The destination station may select the relay signal from each relay station having a metric exceeding at least one threshold. The destination station may process the at least one selected signal to recover a transmission sent by the source station to the destination station.

Abstract: Providing for fair resource sharing among wireless nodes in a wireless communication environment is described herein. By way of example, fairness can comprise establishing a set of resource sharing credits for wireless nodes. By expending credits, a node can borrow a resource of another node, to enable or enhance operation of the borrowing node. Credits for the borrowing node are decreased based on consumption of a shared resource, or credits for the lending node are increased based on such consumption, or both. Once an amount of credits expires, a node can be restricted from borrowing further resources until enough resources are lent to build up a suitable amount of credits. Accordingly, fairness can comprise correlating shared resource consumption with shared resource provisioning, to encourage participation in cooperative wireless communications.

Abstract translation: 本文描述了在无线通信环境中的无线节点之间提供公平的资源共享。 作为示例，公平性可以包括为无线节点建立一组资源共享信用。 通过消耗积分，节点可以借用另一个节点的资源，以启用或增强借用节点的操作。 基于共享资源的消耗，借用节点的贷方减少，或者基于这样的消费增加贷款节点的贷款，或两者。 一旦一定数量的信用额到期，一个节点可以被限制借用进一步的资源，直到足够的资源被借出来建立一个合适数量的信用。 因此，公平性可以包括将共享资源消耗与共享资源供应相关联，以鼓励参与协作无线通信。

Abstract: An adaptable decision parameter is used to determine whether to react to resource utilization messages. The decision parameter may comprise a decision threshold that is adapted based on received resource utilization messages. The decision parameter may comprise a probability that is used to determine whether to react to a received resource utilization message. Such a probability may be based on, for example, one or more channel conditions, the number of interferers seen by a node, the number of received resource utilization messages, or some other form of resource utilization message-related information.
