Abstract
The present specification defines a link adaptation control subfield applicable to a next-generation wireless LAN system including an EHT specification. According to an embodiment described in the present specification, the link adaptation control subfield may include a PS160 subfield. According to another embodiment described in the present specification, the link adaptation control subfield may include a 1-bit MRQ/uplink TB PPDU MFB subfield.
Claims8
A method, comprising:
- generating, by a station (STA), a physical protocol data unit (PPDU) including a control field having a length of 32 bits;
- and
- transmitting, by the STA, the PPDU,
- wherein the control field comprises a first bit, a second bit which is contiguous to the first bit, and aggregate control (A-control) information being contiguous to the second bit,
- wherein the A-control information comprises a Link Adaption (LA) control information 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 information comprises an unsolicited modulation and coding scheme feedback (MFB) subfield, a Modulation and Coding Scheme Request (MRQ) subfield, a number of spatial stream (NSS) subfield, a Modulation and Coding Scheme (MCS) subfield, a resource unit (RU) allocation subfield, a PS160 subfield, a bandwidth (BW) subfield having a length of 3 bits, 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 information 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 information,
- wherein the one-bit subfield is set to one (1) based on the LA control information being related to the EHT LA.

A station (STA), comprising:
- a memory;
- and
- a processor operatively coupled to the memory,
- wherein the processor is configured, with the memory, to cause the transmitting STA to:

- and
- transmitting, by the STA, the PPDU,
- wherein the control field comprises a first bit, a second bit which is contiguous to the first bit, and aggregate control (A-control) information being contiguous to the second bit,
- wherein the A-control information comprises a Link Adaption (LA) control information 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 information comprises an unsolicited modulation and coding scheme feedback (MFB) subfield, a Modulation and Coding Scheme Request (MRQ) subfield, a number of spatial stream (NSS) subfield, a Modulation and Coding Scheme (MCS) subfield, a resource unit (RU) allocation subfield, a PS160 subfield, a bandwidth (BW) subfield having a length of 3 bits, 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 information 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 information,
- wherein the one-bit subfield is set to one (1) based on the LA control information being related to the EHT LA.
