EFFICIENT ADDRESSING AND POWER SAVINGS IN WIRELESS SYSTEMS

A station (STA) comprising: a transmitter configured to transmit information to an access point (AP); a receiver configured to receive, from the AP, a management frame that includes an indication of an assigned group; wherein the transmitter is further configured to transmit, to the AP, an acknowledgement associated with the management frame; wherein the receiver is further configured to receive a data frame, wherein the data frame comprises a data packet and a group identifier; and a processor configured to determine whether the group identifier received in the data frame corresponds to the assigned group, and wherein the processor is further configured to cause the STA to enter a power saving mode on a condition that the group identifier received in the data frame does not correspond to the assigned group.
