Abstract
A method performed by an AP may comprise transmitting a MU-HE-PPDU, on a first 20 MHz channel and a second 20 MHz channel, to a plurality of STAs. The MU-HE-PPDU may comprise an HE-SIG-A portion carried on the first 20 MHz channel and the second 20 MHz channel. The MU-HE-PPDU may comprise a first HE-SIG-B portion carried on the first 20 MHz channel and a second HE-SIG-B portion carried on the second 20 MHz channel.
Claims20
A method performed by an access point (AP), the method comprising:
- transmitting a multi user (MU) high efficiency (HE) physical layer convergence procedure (PLCP) protocol data unit (PPDU) (MU-HE-PPDU), on a first 20 megahertz (MHz) channel and a second 20 MHz channel, from the AP to a plurality of stations (STAs), wherein the MU-HE-PPDU comprises a high efficiency signal A (HE-SIG-A) portion carried on the first 20 MHz channel and the second 20 MHz channel, wherein the MU-HE-PPDU comprises a first high efficiency signal B (HE-SIG-B) portion carried on the first 20 MHz channel and a second HE-SIG-B portion carried on the second 20 MHz channel;
- wherein the HE-SIG A portion indicates a modulation and coding scheme (MCS) of the first HE-SIG-B portion and the second HE-SIG-B portion;
- wherein the first HE-SIG-B portion and the second HE-SIG-B portion comprise different information;
- wherein the first 20 Mhz channel and second 20 Mhz channel are different 20 Mhz channels.

An access point (AP) comprising:
- a transmitter configured to transmit a multi user (MU) high efficiency (HE) physical layer convergence procedure (PLCP) protocol data unit (PPDU) (MU-HE-PPDU), from the AP to a plurality of stations (STAs), wherein the MU-HE-PPDU comprises a high efficiency signal A (HE-SIG-A) portion, the MU-HE-PPDU comprises a first high efficiency signal B (HE-SIG-B) portion and the MU-HE-PPDU comprises a second HE-SIG-B portion, wherein the first HE-SIG-B portion is transmitted on a first channel and the second HE-SIG-B portion is transmitted on a second channel which is different than the first channel;
- wherein the first HE-SIG-B portion includes one or more STA identifiers corresponding to one or more of the plurality of STAs.
A station (STA) comprising:
- a receiver configured to receive, in a high efficiency (HE) signal A (HE-SIG-A) field of a multi user (MU) HE physical layer convergence procedure (PLCP) protocol data unit (PPDU) (MU-HE-PPDU), an indication of a modulation and coding scheme (MCS) of a high efficiency signal B (HE-SIG-B) field of the MU-HE-PPDU;
- the receiver configured to receive the HE-SIG-B field in accordance with the indicated MCS, wherein the HE-SIG-B field comprises a plurality of STA identifiers;
- and
- the receiver configured to receive data of the MU-HE-PPDU, wherein at least one of the STA identifiers of the HE-SIG-B field corresponds to an identifier of the STA.
