Abstract: Providing for dynamic resource provisioning in wireless communication is described herein. By way of example, various wireless performance metrics are collected by respective network access points as an aggregate measure of wireless network performance. Aggregated data can be utilized to generate a performance model for the network and for individual access points. Changes to the data are updated to the model to provide a steady-state characterization of network performance. Wireless resources are generated for respective access points in a manner that optimizes wireless performance. Additionally, resource assignments can be updated at various intervals to re-optimize for existing wireless conditions, whether event driven or based on performance metrics. Accordingly, a robust and dynamic optimization is provided for wireless network resource provisioning that can accommodate heterogeneous access point networks in a changing topology.

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: Techniques for sending signaling messages with beacon signals in a wireless communication network are described. In one design, a transmitter station may map a signaling message (e.g., a reduce interference request) to multiple code symbols. The transmitter station may select multiple resource elements from among a plurality of resource elements based on the multiple code symbols. In one design, each code symbol may be sent across frequency by selecting one of multiple subcarriers in one symbol period. In another design, each code symbol may be sent across time by selecting one of multiple symbol periods on one subcarrier. The transmitter station may generate a beacon signal having transmit power on the selected resource elements and no transmit power on remaining resource elements. The transmitter station may send the beacon signal to at least one receiver station.

Abstract: Systems and methodologies are described that facilitate transmitting control information in wireless networks. Portions of bandwidth can be blanked for transmitting control information, and the control information transmitters can utilize beacon symbols to convey the control information. In this regard, interference is mitigated with respect to data transmissions over the control information bandwidth. Selected frequencies of the beacon symbols in a codeword can be used to indicate the control information. The codewords can be encoded with an error control code to provide redundancy for decoding in the presence of some interference.
