    摘要： Various operations may be performed based on a distance-related function associated with two or more devices. For example, an association procedure for two or more devices may be based on one or more determined distances. Similarly, presence management may be based on one or more determined distances. A distance-related function may take various form including, for example, a distance between devices, two or more distances between devices, a rate of change in a relative distance between devices, relative acceleration between devices, or some combination of two or more of the these distance-related functions.

    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.

    摘要： Techniques for performing erasure detection and power control for a transmission without error detection coding are described. For erasure detection, a transmitter transmits codewords via a wireless channel. A receiver computes a metric for each received codeword, compares the computed metric against an erasure threshold, and declares the received codeword to be “erased” or “non-erased”. The receiver dynamically adjusts the erasure threshold based on received known codewords to achieve a target level of performance. For power control, an inner loop adjusts the transmit power to maintain a received signal quality (SNR) at a target SNR. An outer loop adjusts the target SNR based on the status of received codewords (erased or non-erased) to achieve a target erasure rate. A third loop adjusts the erasure threshold based on the status of received known codewords (“good”, “bad”, or erased) to achieve a target conditional error rate.

    摘要翻译： 描述了用于对没有错误检测编码的传输进行擦除检测和功率控制的技术。 为了擦除检测，发射机经由无线信道发送码字。 接收机计算每个接收到的码字的度量，将所计算的度量与擦除阈值进行比较，并且将所接收的码字声明为“擦除”或“未擦除”。 接收机基于接收到的已知码字来动态地调整擦除阈值，以实现目标性能水平。 对于功率控制，内部环路调整发射功率以将接收信号质量（SNR）保持在目标SNR。 外部环路基于接收到的码字（擦除或未擦除）的状态来调整目标SNR以实现目标擦除率。 第三循环基于接收的已知码字的状态（“好”，“坏”或被擦除）来调整擦除阈值，以实现目标条件错误率。
