Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an AP that requests a plurality of STAs to jointly enable and disable an MRP based on at least one of that each STA of the STAs has uplink traffic with the AP or that each STA of a subset of the STAs has a hidden node. The AP receives, from the STAs, information indicating a communication metric while jointly enabling or disabling the MRP. The AP determines, based on the received information indicating the communication metric, whether the joint enablement of the medium reserving procedure improves communication for the plurality of STAs. The AP requests the STAs to jointly enable the medium reserving procedure for subsequent communication when the joint enablement of the medium reserving procedure improves communication for the plurality of STAs.

Abstract: The present disclosure provides techniques for configuring the utilization of request-to-send/clear-to-send (RTS/CTS) protocol procedures based on varying conditions at the STA. For example, an AP may identify one or more conditions, when satisfied, may trigger the STA to either enable or disable uplink (UL) transmissions associated with a RTS/CTS protocol procedure. In some aspects, an AP may determine a transmit opportunity (TXOP) threshold for an STA and may determine whether to broadcast a message having the TXOP threshold to multiple STAs including the STA or unicast the message to the STA. An STA may receive a message from an AP having a TXOP threshold and may replace, based on an indication in the received message, a current TXOP threshold in the STA with the TXOP threshold in the received message. The STA may transmit an UL RTS frame in response to a determination that a planned TXOP duration satisfies the TXOP threshold.

Abstract translation: 本公开提供了用于基于STA处的变化条件来配置请求发送/清除发送（RTS / CTS）协议过程的利用的技术。 例如，AP可以在满足时识别一个或多个条件，可以触发STA来启用或禁用与RTS / CTS协议过程相关联的上行链路（UL）传输。 在一些方面，AP可以确定STA的发送机会（TXOP）阈值，并且可以确定是否将具有TXOP阈值的消息广播到包括STA的多个STA，或将消息单播到STA。 STA可以从具有TXOP阈值的AP接收消息，并且可以基于接收到的消息中的指示，以接收到的消息中的TXOP阈值来替换STA中的当前TXOP阈值。 响应于确定计划的TXOP持续时间满足TXOP阈值，STA可以发送UL RTS帧。

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) or access point (AP)) may decode at least a portion of a preamble of a received packet to determine whether the packet is sent by a member of an OBSS (e.g., STA or 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 to reduce delay in scheduling traffic transmissions by resuming the backoff operations prior to expiration of the period reserved for an OBSS packet by the network allocation vector (NAV). In other words, 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 translation: 公开了通过修改退避机制来减少重叠基本服务集（OBSS）环境中调度业务传输的延迟的技术。 在一些示例中，设备（例如，站（STA）或接入点（AP））可以对接收到的分组的前导码的至少一部分进行解码，以确定分组是否由OBSS的成员发送（例如，STA 或来自不同BSS的AP）。 作为解码的结果，退避操作通常被延迟。 本公开的方面提供了一种方法，装置和系统，用于通过网络分配向量（NAV）在为OBSS分组保留的周期期满之前恢复回退操作来减少调度业务传输的延迟。 换句话说，设备可能不符合OBSS分组的NAV，而是通过在OBSS分组的NAV期间在相同频率信道上发送另一分组（或信号）来执行空间重用。

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an AP. The AP determines an interference metric of a BSS having a plurality of STAs. The AP is in the BSS. The interference metric indicates a degree of interference in the BSS caused by one or more hidden nodes associated with the plurality of STAs. The AP determines whether the interference metric meets a threshold. The AP transmits, to the plurality of STAs, a frame including an indicator when the interference metric meets the threshold. The indicator indicates to each of the plurality of STAs to enable a medium reserving procedure. The medium reserving procedure reserves a medium for data transmission.

Abstract: The present disclosure presents methods and apparatuses for providing a simplified channel quality indicator associated with a serving channel to a serving wireless node, so that the load and delay for feedback can be minimized. For example, the present disclosure describes example methods of channel quality indicator determination and reporting by a user equipment (UE), which may include measuring a serving channel of a wireless node and calculating a binary channel quality indicator that identifies a general quality of a serving channel of the wireless node. Additionally, example methods may include transmitting the binary channel quality indicator from the UE to the wireless node. Furthermore, upon successful receipt of the binary channel quality indicator, the wireless node may alter one or more channel characteristics based on the binary channel quality indicator, thereby providing improved user experience at the UE.
