Signaling method for multiplexing different amendment devices in an enhanced wireless local area network

A method for communicating in a wireless network, the method comprising:

• setting, by an access point, a type bit in a trigger frame to indicate a type of the trigger frame, wherein the type bit indicates whether the trigger frame is scheduling an uplink transmission for only a first set of stations in the wireless network or the first set of stations and a second set of stations in the wireless network;
• configuring, by the access point, a common information field of the trigger frame, wherein the common information field is to be used by (1) all stations in the first set of stations for performing the uplink transmission and (2) when the type bit indicates that the trigger frame is scheduling the uplink transmission for the first set of stations and the second set of stations in the wireless network, all stations in the second set of stations for performing the uplink transmission;
• configuring, by the access point, a set of user information fields of the trigger frame, wherein the set of user information fields is to be used by (1) all stations in the first set of stations for performing the uplink transmission and (2) when the type bit indicates that the trigger frame is scheduling the uplink transmission for the first set of stations and the second set of stations in the wireless network, all stations in the second set of stations for performing the uplink transmission;
• and
• transmitting, by the access point, the trigger frame to (1) all stations in the first set of stations when the type bit indicates that the trigger frame is scheduling the uplink transmission for the first set of stations and (2) all stations in the second set of stations when the type bit indicates that the trigger frame is scheduling the uplink transmission for the first set of stations and the second set of stations.
