Abstract: A method for updating an associated ID (AID) in a network when a Basic Service Set (BSS) color change occurs is provided. The network includes an Access Point (AP) and a plurality of associated stations (STAs). The method includes: detecting a color collision; setting a new BSS color in response to the color collision; configuring an AID update request frame, wherein an updated AID according to the new BSS color is inserted into a subElement Information Element (IE) field of the AID update request frame; and sending the AID update request frame to the plurality of associated STAs to inform the associated STAs of the updated AID.

Abstract: Examples pertaining to synchronization of one or more clients and an access point (AP) during channel switch in wireless communications are described. An apparatus acting as an AP of a wireless network transmits a channel switch announcement (CSA) on a first channel to each of one or more clients in the wireless network. The AP then performs a channel switch from the first channel to a second channel. The AP also determines whether at least a first client of the one or more clients has switched to the second channel by transmitting a unicast frame on the second channel to the first client.

Abstract: Examples pertaining to adaptive traffic indication map (TIM) setup policy for client devices in power-save mode in a dense environment are provided. An apparatus may determine an amount of available time for access to a transmission medium. The apparatus (e.g., access point) may select a subset of one or more communication devices from a plurality of communication devices (e.g., client devices) associated with the apparatus based at least in part on the amount of available time. The apparatus may also signal to the selected subset of the one or more communication devices to cause the one or more communication devices to switch from a first mode to a second mode. The apparatus may further transmit buffered data to at least one communication device of the subset of one or more communication devices during the available time.
