The first AP advertises, to one or more stations (STAs) within a basic service set (BSS) of the first AP, a TWT schedule that is identical to the first TWT schedule established by the second AP. When a second TWT schedule is established by the second AP, the first AP advertises, to the one or more STAs within the BSS of the first AP, a TWT schedule that is identical to the second TWT schedule established by the second AP.

The sub-device will negotiate a power saving time and a wake-up time for the STA with the associated STA, i.e. When the STA is in a power saving state and when to handle a wake-up state. And then, the sub-device reports the negotiated wake-up time of the STA to the master device. And further, the master device schedules related data of the STA according to the wake-up time of the STA. Thus, before performing service scheduling on each STA, the master device can acquire the STA wake-up time negotiated by each sub-device and the associated STA in advance, and does not need to frequently interact with each sub-device to acquire the real-time state of each STA. The master device can more efficiently perform service scheduling on each STA at a proper time by centrally managing and controlling the wake-up time of each STA.

A wireless communication protocol using CSMA / CA, EDCA and R-TWT to prioritize RTA traffic transmissions. During an R-TWT SP, the RTA traffic is prioritized for transmission and mechanisms are provided for assuring proper indications and termination of the R-TWT SP.

Some aspects provide an approach for optimizing sleep quality by addressing several components of sleep: falling asleep, maintaining sleep, and waking up refreshed. Some aspects include example systems, devices, and techniques that describe the significance of distal and core body temperatures to achieve these sleep components. For example, by facilitating an increase in distal skin temperature, the example systems, devices, and techniques promote a decrease in core body temperature, which can be associated with reduced sleep onset latency.

These example systems, devices, and techniques allow for a tailored sleep environment (e.g., an in-bed microenvironment) that adapts to the physiological needs of the user, contributing to overall improved sleep quality and user satisfaction.
