DETAILED DESCRIPTION The following description and the drawings sufficiently illustrate specific embodiments to enable those skilled in the art to practice them.

Portions and features of some embodiments may be included in, or substituted for, those of other embodiments. Embodiments set forth in the claims encompass all available equivalents of those claims. IEEE 802.11bf (“11bf”) is a standard that aims to standardize Wi-Fi sensing that uses Wi-Fi technology to perform radar-like applications such as detecting motion in a room or detecting when a person approaches a target device. Sensing is performed by tracking channel estimates obtained when decoding multiple Wi-Fi packets over time and detecting variations that indicate an event of interest. Sensing by proxy (SBP) is a mechanism adopted in 11bf to enable a non-AP STA to obtain sensing measurements of the channel between an AP and one or more other non-AP STAs or between a receive antenna and a transmit antenna of an AP. With the execution of an SBP procedure, a non-AP STA can obtain sensing measurements necessary for detecting and tracking changes in the environment, which otherwise the non-AP STA would not be able to perform due to its limited information of the other non-AP STAs. Currently, TGbf (11bf task group) has defined a basic protocol to support SBP. Basically, a non-AP STA acting as an SBP initiator sends an SBP Request frame to an SBP responder capable AP to indicate its intent to ask the AP to initiate or invoke a sensing procedure and perform sensing measurement with other non-AP STAs. Once agreed, the SBP responder (e.g., the AP) sends an SBP Response frame with the status code SUCCESS and then follows the regular WLAN sensing procedure. In one or more embodiments, an enhanced sensing system may facilitate that the SBP initiator can either request the AP to perform a WLAN sensing procedure with specific non-AP STAs on a list provided by the SBP initiator, or the SBP initiator can simply provide a set of requirements for the non-AP STAs without identifying specific non-AP STAs. The former is applicable in scenarios where the SBP initiator somehow already knows the information of some other non-AP STAs using implementation-specific methods, while the latter is applicable in scenarios where the SBP initiator does not know any other non-AP STAs nearby and therefore can only rely on the AP to find non-AP STA responders. In the SBP Request frame, it is proposed to add information (e.g., a sensing measurement parameters information element) regarding timing and scheduling information of requested sensing measurement report from the
