1. A method in a wireless Local Area Network (WLAN) system, the method comprising:
generating, by a station (STA), a control field having a length of 32 bits; and
transmitting, by the STA, the control field,
wherein the control field comprises a first bit which is denoted by B0, a second bit which is contiguous to the first bit and is denoted by B1, and aggregate control (A-control) information being contiguous to the second bit,
wherein the A-control information comprises a Link Adaption (LA) control subfield having a length of 26 bits based on the first bit having a value of one (1) and the second bit having a value of one (1),
wherein the LA control subfield comprises an unsolicited modulation and coding scheme feedback (MFB) subfield having a length of 1 bit, an MCS Request (MRQ) subfield having a length of 1 bit and being contiguous to the unsolicited MFB subfield, a number of spatial stream (NSS) subfield being contiguous to the MRQ subfield, an MCS subfield having a length of 4 bits and being contiguous to the NSS subfield, a resource unit (RU) allocation subfield having a length of 8 bits and being contiguous to the MCS subfield, a PS160 subfield having a length of 1 bit and being contiguous to the RU allocation subfield, a bandwidth (BW) subfield having a length of 3 bits and being contiguous to the PS160 subfield, a MRQ sequence identifier (MSI)/partial PPDU parameter subfield being contiguous to the BW subfield, and a transmit (TX) beamforming subfield having a length of 1 bit and being contiguous to the MSI/partial PPDU parameter subfield, and a one-bit subfield related to whether the LA control subfield is related to an Extremely High Throughput (EHT) LA,
wherein the one-bit subfield is located on a twenty sixth bits which is denoted by B25 in the LA control subfield,
wherein the one-bit subfield is set to one (1) based on the LA control subfield being related to the EHT LA.
