摘要： Embodiments of the invention provide signaling mechanisms for wireless networks composed of a large number of stations. An example method embodiment comprises: storing, by a wireless device, a prior channel estimate that was previously transmitted to another wireless device in a wireless network; receiving, by the wireless device, a request message from the other device, to determine a distortion between a current channel estimate and the prior channel estimate and compare the determined distortion to a distortion threshold value, the request message being a broadcast request message or a measurement request message and the distortion value being either included in the request message, received in another message, or a preconfigured value; determining, by the wireless device, the distortion between the current channel estimate and the prior channel estimate and comparing the determined distortion to the distortion threshold value; and transmitting, by the wireless device, one or more parallel or sequential messages to the other device, indicating presence of the determined distortion greater than the distortion threshold value or indicating an inability to determine a distortion in channel estimates.
