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： 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 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： Systems and methods are described that facilitate performing interference management techniques between sending and receiving nodes in order to provide minimum transmission rate guarantees. Carrier-to-interference ratio (C/I) may be controlled by employing specialized resource utilization messages (RUMs), the number and rate of which may be governed by a “token bucket” mechanism. For instance, a maximum token bucket size may be defined for a node, which describes the maximum amount of data that may pass through the node at a given time. A current number of tokens in the node's bucket may be evaluated and compared to a threshold value, and RUMs may be transmitted by the node as long as the current token number is greater than the predefined threshold value. Tokens may additionally be deducted from the node's bucket for successful data transmissions, thus providing a dynamic interference control mechanism.
摘要翻译：描述了有助于在发送和接收节点之间执行干扰管理技术的系统和方法，以便提供最小的传输速率保证。可以通过使用专门的资源利用消息（RUM）来控制载波干扰比（C / I），其数量和速率可以由“令牌桶”机制来管理。例如，可以为节点定义最大令牌桶大小，该节点描述在给定时间可能通过节点的最大数据量。可以评估节点桶中当前的令牌数量并将其与阈值进行比较，并且只要当前令牌数大于预定义的阈值，则可以由节点发送RUM。额外地从节点的桶中扣除令牌以成功进行数据传输，从而提供动态干扰控制机制。

摘要： Systems and methods are described that facilitate controlling transmission/reception time slots in a wireless multi-hop ad hoc network. A node, such as an access terminal or an access point, may select an identifier that corresponds to specific time slots during which nodes with that particular identifier may transmit and/or receive. Nodes that are one hop away from each other may select different identifiers in order to ensure that neighboring nodes do not transmit and/or receive during the same time slots. In this manner, interference caused and/or experienced by a given node may be reduced.

摘要： Systems and methodologies are described that facilitate mitigating a hidden node condition in a wireless mesh network wherein nodes utilize a request-to-send/clear-to-send (RTS/CTS) protocol in conjunction with an asynchronous hybrid automatic repeat request protocol. For instance, a node may contend for a set of subcarriers by sending an RTS signal over the desired subcarriers, and may receive a CTS signal over the contended subcarriers, wherein the CTS signal indicates which subcarriers the node may transmit data over. If another node has won the contention for a particular subcarrier, requesting node may adjust a power level at which it transmits an RTS or a data packet in order to permit the requesting node to utilize the subcarrier without interfering with the winning node.
