CPC H04W 74/0816 (2013.01) [H04W 72/0453 (2013.01); H04W 72/52 (2023.01); H04W 84/12 (2013.01); H04W 88/08 (2013.01)] | 13 Claims |
1. A device for facilitating wireless communication in a transmission opportunity (TXOP), the device comprising:
one or more memories; and
one or more processors coupled to the one or more memories, the one or more processors configured to cause:
receiving a multi-user (MU) physical layer protocol data unit (PPDU);
obtaining a bandwidth of the MU PPDU based on a subfield in a signal field, the bandwidth of the MU PPDU being 80 MHz, 160 MHz, or 80+80 MHz,
wherein the 80 MHz bandwidth comprises a primary 20 MHz subchannel, a secondary 20 MHz subchannel, and a secondary 40 MHz subchannel, the secondary 40 MHz subchannel comprising two 20 MHz subchannels,
wherein the subfield is set to a first value to indicate that the MU PPDU has 80 MHz bandwidth and the secondary 20 MHz subchannel is punctured, and
wherein the subfield is set to a second value to indicate that the MU PPDU has 80 MHz bandwidth and one of the two 20 MHz subchannels in the secondary 40 MHz is punctured; and
processing the MU PPDU using the bandwidth of the MU PPDU,
wherein the subfield is set to the first value when two 20 MHz subchannels in the secondary 40 MHz subchannel are idle during an interval of point coordination function interframe space (PIFS) immediately preceding a start of the TXOP, and
wherein the subfield is set to the second value when the secondary 20 MHz subchannel and the other of the two 20 MHz subchannel in the secondary 40 MHz subchannel are idle during the interval of PIFS immediately preceding a start of the TXOP.
