Multiple bssid procedure with tim encoding

An apparatus for wireless communications, comprising:

• an interface for receiving a frame containing an information element (IE), wherein the IE comprises a partial virtual bitmap field that indicates zero or more basic service sets (BSSs) that have buffered group-cast traffic and at least one encoded subfield that identifies at least one individual BSS having buffered group-cast traffic using one or more bits of an identifier of the individual BSS;
• and
• a processing system configured to determine the presence of buffered group-cast traffic for the apparatus based on the partial virtual bitrnap and to decide whether or not to change at least one power state to receive the buffered group-cast traffic, based on the determination.

A method for wireless communications by an apparatus, comprising:

• generating, at an apparatus, a frame with an information element (IE) having a partial virtual bitmap field that indicates zero or more basic service sets (BSSs) that have buffered group-cast traffic, wherein the partial virtual bitmap field comprises at least one encoded subfield that identifies at least one individual BSS having buffered group-cast traffic using one or more bits of an identifier of the individual BSS;
• and
• outputting the frame containing the IE for transmission.
