1. A wireless station (STA) associated with an access point (AP) belonging to a multiple basic service set identifier (BSSID) set including a transmitted BSSID (Tx BSSID) and one or more non-transmitted BSSIDs (non-Tx BSSIDs), the STA comprising:
one or more processors; and
a memory storing instructions that, when executed by the one or more processors, causes the STA to:
receive a management frame carrying a traffic indication map (TIM) element including a partial virtual bitmap containing a group association identifier (AID) mapping; and
receive a trigger frame allocating random access resource units (RUs) for uplink (UL) transmissions associated with the multiple BSSID set using at least one AID value based on the group AID mapping contained in the partial virtual bitmap of the TIM element, the at least one AID value being an AID value set to zero, an AID value set to 2045, or an AID value set to 2047.
