Claim:
1. A method for use in a station for transmitting an acknowledgement in wireless communication, the method comprising: receiving, from an access point (AP), a data frame that includes an indication that a null data packet (NDP) acknowledgement (ACK) frame is requested for acknowledgement, wherein the indication that an NDP ACK frame is requested for acknowledgement enables an unintended station that is not an intended recipient of the data frame to detect the indication that an NDP ACK frame is requested for acknowledgement of the data frame and ignore the NDP ACK frame based on the detection; and transmitting an NDP ACK frame in response to the received data frame, wherein the NDP ACK frame includes an indication that the NDP ACK frame is an NDP ACK frame, and includes an ACK sequence based on the received data frame.
