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 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.

摘要： 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.

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： 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.
摘要翻译：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。

摘要： To transmit overhead information for broadcast and multicast services in a system that utilizes multiple radio technologies, time slots used for OFDM in a super-frame are initially ascertained. Overhead information for multiple streams to be sent in the time slots used for OFDM is generated. The overhead information conveys the time slots and the coding and modulation used for the streams and may be given in various forms. Multiple records may be formed for the overhead information for the streams. The overhead information for the streams is processed and time division multiplexed with the data for the streams in the super-frame. Information indicating the time slots used for OFDM in the super-frame may be sent separately or included in the overhead information. An indicator may also be appended to each stream to indicate whether there is any change in the overhead information for the stream in the next super-frame.

摘要： Techniques for scheduling UEs are described. In one design, a scheduler (e.g., for a cell) may receive channel direction information (CDI) and channel strength information (CSI) from a plurality of UEs. In one design, the CDI from each UE may include at least one eigenvector, and the CSI from each UE may include at least one singular value corresponding to the at least one eigenvector. The scheduler may schedule at least one UE among the plurality of UEs for data transmission based on the CDI and CSI from the plurality of UEs. The scheduler may select the at least one UE based on a metric related to signal-to-leakage ratio (SLR), or spectral efficiency, etc. In one design, the scheduler may evaluate the performance of different sets of UEs to determine whether to schedule one UE for single-user MIMO or multiple UEs for multi-user MIMO.

摘要： 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.

摘要： In a system where multiple resources are available for carrying traffic, a scheduler may give higher scheduling priority to those resources for which a RUM has been sent. For example, if a node has sent a RUM to reserve a specified carrier of a set of allocated carriers, the scheduler may first attempt to schedule traffic on the specified carrier since there may be less interference on this carrier as a result of the RUM.
摘要翻译：在具有多个资源可用于携带业务的系统中，调度器可以向已经发送了RUM的资源给予更高的调度优先级。例如，如果节点已经发送RUM以保留一组分配的载波的指定载波，则调度器可以首先尝试在指定载波上调度业务，因为作为RUM的结果可能对该载波的干扰较小。
