Abstract: Methods, systems, and devices for wireless communication are described. One method may include communicating with an access point (AP) during awake intervals in which the wireless device is in an awake mode, determining a congestion level associated with a radio frequency (RF) spectrum band, and determining, for an awake interval, an inactivity timeout (ITO) interval for the wireless device to remain in the awake mode based on an identified RF spectrum band and the determined congestion level used by the wireless device to communicate with the AP. A second method may include polling an AP during a delivery traffic indication message (DTIM) period, and modifying timing for the station to poll the AP based on identifying that a trigger condition has been satisfied based on a determination that at least one null data message has been received from the AP, or a predetermined threshold number of polls have timed out.

Abstract translation: 描述了用于无线通信的方法，系统和设备。 一种方法可以包括在无线设备处于苏醒模式的清醒间隔期间与接入点（AP）进行通信，确定与射频（RF）频谱带相关联的拥塞等级，以及针对清醒间隔确定 基于所识别的RF频谱带和由所述无线设备与所述AP进行通信所使用的所确定的拥塞等级，使所述无线设备保持在所述唤醒模式中的非活动超时（ITO）间隔。 第二种方法可以包括：在传递业务指示消息（DTIM）时段期间轮询AP，以及基于确定满足触发条件，基于确定至少一个空数据消息 已经从AP收到，或预定的阈值数量的民意调查超时。

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus is configured to receive a traffic indication map (TIM) from an access point (AP). The apparatus is configured to transmit, in a network sleep state, a predetermined number of power-save (PS) polls to the AP based on the TIM. The apparatus is configured to receive, in the network sleep state, one or more data packets from the AP in response to each of the predetermined number of PS polls.
