In some cases, a network entity may obtain an update during a communication session, such as a sensing measurement session. The network entity may then output a notification of the update to another wireless device. The network entity may also output the actual update itself. ## Claims ### Claim 1 An apparatus for wireless communications, comprising: at least one memory comprising computer-executable instructions; and one or more processors configured to execute the computer-executable instructions and cause the apparatus to: obtain, at a first wireless node during a current communication session, an update associated with at least one parameter; and output, for transmission, a notification of the update to a second wireless node that is in an unassociated state. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the update comprises at least one of: a transmit power envelope (TPE) update or a spatial stream change. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the notification is output for transmission during a sensing measurement exchange sequence. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the notification is output for transmission via a trigger frame. ### Claim 5 (depends on 4) The apparatus of claim 4, wherein the notification is output for transmission via one or more bits of at least one of: a common information field of the trigger frame, a user information field of the trigger frame, a trigger dependent field of the trigger frame, or a basic service set (BSS) parameter change count field of the trigger frame. ### Claim 6 (depends on 4) The apparatus of claim 4, wherein the one or more processors are further configured to cause the apparatus to: output, for transmission, the update via at least one of a beacon frame or a probe response frame. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the one or more processors are further configured to cause the apparatus to: obtain a query frame;
