    Abstract: When a first node cannot hear a second node, the second node is “hidden” to the first node. In response to receiving a trigger frame, the two nodes may inadvertently transmit response frames at approximately the same time. The response frames may collide with each other, thereby causing delays in node discovery in a NAN. Provided herein are methods, apparatuses, and computer program products for reducing collisions in wireless communication. In some configurations, nodes may receive trigger frames that indicate a reduction in the rate that response frames are transmitted when traffic load conditions are high. In some configurations, nodes located in different coverage areas (e.g., a “hidden area” and a “non-hidden area”) may transmit response frames at different times. In some configurations, the nodes may refrain from transmitting their response frames upon hearing that another node having a higher serving preference rank is transmitting.

    Abstract translation: 当第一个节点听不到第二个节点时，第二个节点对第一个节点“隐藏”。 响应于接收到触发帧，两个节点可能在大约相同的时间无意中发送响应帧。 响应帧可能相互碰撞，从而导致NAN中节点发现的延迟。 本文提供了用于减少无线通信中的冲突的方法，装置和计算机程序产品。 在一些配置中，节点可以接收触发帧，其指示当业务负载条件较高时响应帧被发送的速率的降低。 在一些配置中，位于不同覆盖区域（例如，“隐藏区域”和“非隐藏区域”）中的节点可以在不同时间发送响应帧。 在一些配置中，当听到具有较高服务偏好等级的另一个节点正在发送时，节点可以避免发送它们的响应帧。

    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for wireless range extension for communication in a wireless local area network (WLAN). In some aspects, a first WLAN device and a second WLAN device may exchange one or more management frames advertising support for a non-orthogonal frequency-division multiplexing (non-OFDM) data rate for communications via one or more non-2.4 GHz bands. In some aspects, the non-OFDM data rate may be a data rate of a plurality of data rates associated with an IEEE 802.11b standard, and the one or more non-2.4 GHz bands may include one or more of a 3.5 GHz band, a 5 GHz band, a 6 GHz band, a 45 GHz band, and a 60 GHz band. The first and second WLAN devices may select the non-OFDM data rate and at least one of the non-2.4 GHz bands for exchange data communications.

    Abstract: This disclosure provides methods, components, devices, and systems that support information exchanges for coordinated access point (CAP) operations. Some aspects more specifically relate to transmitting and receiving CAP-specific parameters to facilitate transmit opportunity (TXOP) sharing between a first access point (AP) and one or more second APs. For example, the first AP (such as a sharing AP) may use CAP-specific parameters provided by the one or more second APs (such as shared APs) to determine a CAP sharing schedule for a TXOP. The CAP-specific parameters may include static capability parameters and dynamic parameters. The static capability parameters may include supported CAP modes, association identifiers (AIDs), and processing times, while the dynamic parameters may include medium access demands, traffic priority information, and service period information. The first AP may advertise the CAP sharing schedule to the one or more second APs via an announcement frame.

    Abstract: This disclosure provides methods, devices and systems for reducing power consumption in neighbor awareness networking (NAN) devices. Some implementations more specifically relate to dynamically adjusting a NAN device link (NDL) schedule to reduce the idle duration of a NAN data interface (NDI). The NDL schedule identifies a number of NAN slots, per discovery window (DW) interval, during which an NDL is available for data communications between NAN devices. In some aspects, a NAN device may measure congestion on the wireless channel during each NAN slot within a DW interval and may dynamically update the NDL schedule based on the measured congestion. In some other aspects, a NAN device may measure throughput on the NDL during each NAN slot within a DW interval and may dynamically update the NDL schedule based on the measured throughput.

    Abstract: This disclosure provides methods, devices and systems for performing a single-sided ranging operation. In some implementations, a first device transmits a first frame to a wireless station (STA), and receives a second frame from the STA responsive to the first frame. The first device obtains information indicating a time period between transmission of the first frame and reception of the second frame by the first device, and obtains information indicating time delays associated with a plurality of second devices, where each of the time delays is between respective receptions of the first frame and the second frame by a respective one of the second devices. The first device obtains a position of the STA based on the time period, the time delays associated with the plurality of second devices, and signal propagation times between the first device and each of the plurality of second devices.
