Abstract
The present specification proposes a configuration of a trigger frame for triggering transmission of an A-PPDU. According to an embodiment of the present specification, a bandwidth for an A-PPDU and/or a PPDU triggered according to a combination of values indicated by an uplink bandwidth subfield and a bandwidth extension subfield may be indicated.
Claims6
A method in a wireless LAN system, the method comprising:
- transmitting a trigger frame to at least one of a first station (STA) and a second STA,
- wherein the first STA is a High Efficiency (HE) STA, and the second STA is an Extremely High Throughput (EHT) STA,
- wherein the trigger frame includes a common field including an uplink bandwidth subfield having a length of 2 bits informing a first value and a special user information field including an uplink bandwidth extension subfield having a length of 2 bits informing a second value;
- and
- based on the trigger frame, receiving at least one of an HE trigger-based (TB) physical protocol data unit (PPDU) transmitted from the first STA and an EHT TB PPDU transmitted from the second STA,
- wherein a combination of the first value and the second value informs a first bandwidth configured for the HE TB PPDU and a second bandwidth configured for the EHT TB PPDU,
- wherein based on the first value being 0 and the second value being 0, the combination informs that the first bandwidth is 20 MHz and the second bandwidth is 20 MHz,
- wherein based on the first value being 1 and the second value being 0, the combination informs that the first bandwidth is 40 MHz and the second bandwidth is 40 MHz,
- wherein based on the first value being 2 and the second value being 0, the combination informs that the first bandwidth is 80 MHz and the second bandwidth is 80 MHz included in a Secondary 160 MHz band,
- wherein based on the first value being 2 and the second value being 1, the combination informs that the first bandwidth is 80 MHz and the second bandwidth is 160 MHz included in the Secondary 160 MHz band,
- wherein based on the first value being 2 and the second value being 2, the combination informs that the second bandwidth is 80 MHz included in a Primary 80 MHz band,
- wherein based on the first value being 2 and the second value being 3, the combination informs that the second bandwidth is 160 MHz included in a Primary 160 MHz band.
