CPC H04L 69/22 (2013.01) [H04L 27/18 (2013.01); H04W 84/12 (2013.01)] | 27 Claims |
1. A method in a wireless local area network (WLAN) system, the method comprising:
receiving a physical protocol data unit (PPDU),
wherein the PPDU includes a legacy signal field, a control signal field contiguous to the legacy signal field, and a data field,
wherein the legacy signal field is received through a first symbol, and the control signal field is received through a second symbol,
wherein the legacy signal field and the control signal field are generated based on a binary phase shift keying (BPSK) constellation,
wherein the legacy signal field is generated based on a first signal bit,
wherein the control signal field is generated based on a second signal bit, and
wherein the second signal bit includes a first control bit for identifying that the PPDU is an extreme high throughput (EHT) PPDU and a second control bit including information of a duration of transmission opportunity (TXOP) related to the PPDU; and
decoding the PPDU based on the control signal field.
