    Abstract: Techniques for reducing delay in scheduling traffic transmission in an overlapping basic service set (OBSS) environment by modifying backoff mechanisms are disclosed. In some examples, a device (e.g., station (STA), access point (AP)) decodes at least a portion of a preamble of a packet to determine whether the packet is sent by a member of an OBSS (e.g., STA, AP from a different BSS). Backoff operations are typically deferred as a result of the decoding. Aspects of the present disclosure provide a method, apparatus, and system in which the backoff operations are resumed prior to expiration of the period reserved for an OBSS packet by the network allocation vector (NAV). That is, the device may not honor the NAV of the OBSS packet, and instead perform spatial reuse by transmitting another packet (or signal) on the same frequency channel during the NAV of the OBSS packet.

    Abstract: A first AP in a wireless network determines that a wireless client device should re-associate from the first AP to a second AP of the wireless network. The first AP communicates an AP coordination message from the first AP to the second AP to share coordination information with the second AP. The first AP coordinates with the second AP to cause the re-association of the wireless client device in accordance with the coordination information. The first and second AP may coordinate directly to synchronize re-association activities. Re-association activities may include the use of a configuration message to the wireless client device, managing transmit power of beacon messages from the first and second APs, or forced disassociation and blocking. The first AP may maintain a record of which re-association activity was successful in causing the wireless client device to re-associate to the second AP.

    Abstract: Methods, systems, and devices are described for wireless communication. A transmitting device may transmit soliciting frames to a receiving device on a forward link. In response to the soliciting frames, the receiving device may transmit solicited frames in an immediate response back to the transmitting device on a reverse link. A solicited frame may fail to successfully decode at the transmitting device. The transmitting device in response may indicate an instantaneous value for one or more reverse link transmission parameters when sending a subsequent soliciting frame. The reverse link transmission parameters may be predetermined in a fixed mapping such that one or more values for the reverse link transmission parameters depend on values for the forward link transmission parameters. The receiving device may override the predetermined value and instead use the instantaneous value. An indicator of the instantaneous value may also be sent in a control field.

    Abstract translation: 描述了用于无线通信的方法，系统和设备。 发送设备可以向前向链路上的接收设备发送请求帧。 响应于请求帧，接收设备可以在反向链路上将所请求的帧立即发送回发送设备。 被请求的帧可能无法在发送设备上成功解码。 作为响应的发送装置可以在发送后续请求帧时指示一个或多个反向链路传输参数的瞬时值。 反向链路传输参数可以在固定映射中预先确定，使得用于反向链路传输参数的一个或多个值取决于前向链路传输参数的值。 接收设备可以覆盖预定值，而是使用瞬时值。 也可以在控制区域中发送瞬时值的指示符。

    Abstract: To provide more efficient FDRA or MCS for some frequency ranges, methods, apparatuses, and computer-readable medium are provided. An example method may include receiving, from a base station and via RRC signaling, one or more FDRA or MCS configurations that are based on a frequency range. The example method may further include communicating with the base station over the frequency range, using an FDRA or MCS based on at least one of the one or more FDRA or MCS configurations.
