Claim 14:
15. An apparatus for an extremely high throughput (EHT) station (STA) (EHT STA), the apparatus comprising:
processing circuitry; and memory, the processing circuitry configured to:
decode an EHT multi-user (MU) physical layer protocol data unit (PPDU) (EHT MU PPDU) from an EHT access point (EHT AP) transmitted to multiple EHT STAs, wherein a preamble portion of the EHT MU PPDU includes a universal SIGNAL field (U-SIG) followed by an EHT-SIG field,
wherein the EHT MU PPDU comprises one of:
a 240 MHz EHT PPDU when the EHT MU PPDU occupies a channel bandwidth of 240 MHz;
a 160 MHz EHT PPDU when the EHT MU PPDU occupies a channel bandwidth of 160 MHz; and
a 320 MHz EHT PPDU when the EHT MU PPDU occupies a channel bandwidth of 320 MHz,
wherein the EHT MU PPDU comprises a plurality of two or more 80 MHz portions including one primary 80 MHz portion and one or more secondary 80 MHz portions, wherein the preamble portion is separately encoded for each 80 MHz portion, wherein the EHT-SIG is encoded to indicate a receiver address (RA) and resource unit allocation, and
wherein the U-SIG for the primary 80 MHz portion is encoded to indicate whether any one or more of the multiple EHT STAs will need to decode the EHT-SIG transmitted on one of the secondary 80 MHz portions to obtain receive address (RA) information.
