Full bandwidth multicast indication to multiple users

A method for wireless communication, comprising:

• receiving a preamble of a multiple user transmission that comprises a first wireless local area network (WLAN) signaling field followed by a second WLAN signaling field;
• identifying, in the first WLAN signaling field, a compression indicator for the second WLAN signaling field and an indication of a number of stations associated with the multiple user transmission, wherein the number of stations is greater than a predetermined threshold number of stations;
• identifying, in the second WLAN signaling field, a spatial configuration indicator for the multiple user transmission based at least in part on the identified compression indicator and the number of stations;
• and
• determining a spatial decoding scheme for the multiple user transmission based at least in part on the identified spatial configuration indicator and the number of stations.

An apparatus for wireless communication, comprising:

• a memory that stores instructions;
• and
• a processor coupled with the memory, wherein the processor and the memory are configured to:
• determine that a number of stations to receive a multiple user transmission is greater than a predetermined threshold number of stations;
• generate, in a first wireless local area network (WLAN) signaling field, a compression indicator for a second WLAN signaling field and an indication of the number of stations based at least in part on determining that the number of stations is greater than the predetermined threshold number of stations;
• generate, in the second WLAN signaling field, a spatial configuration indicator for the multiple user transmission based at least in part on the number of stations;
• and
• transmit a preamble of the multiple user transmission that comprises the first WLAN signaling field followed by the second WLAN signaling field.
