Claim:
1. A method comprising: receiving a first beacon frame at a station prior to entering into a low power mode, wherein the first beacon frame is configured to indicate first configuration parameters associated with an access point; in response to transitioning out of the low power mode, transmitting, from the station to the access point, a frame requesting updated configuration parameters included in a beacon frame missed by the station while the station was operating in the low power, wherein the frame includes information associated with the first configuration parameters received from the access point prior to the station entering into the low power mode; in response to transmitting the frame, receiving an update frame from the access point when the first configuration parameters are different than current configuration parameters associated with the access point, the update frame configured to indicate a change in at least one of the configuration parameters associated with the access point; and updating configuration parameters at the station based on the change in the at least one of the configuration parameters.
