METHOD AND DEVICE FOR INDICATING VARIOUS NG VALUES IN ACCORDANCE WITH SUPPORT OF SPATIAL STREAM IN WIRELESS LAN SYSTEM

Document Type and Number:

WIPO Patent Application WO/2023/008834

Kind Code:

A1

Abstract:

Proposed are a method and device for transmitting a MIMO control field in a wireless LAN system. Particularly, a receiving STA: generates a MIMO control field for providing feedback on channel information; and transmits the MIMO control field to the transmitting STA. The MIMO control field comprises a grouping subfield and a reserved subfield. The channel information on which the feedback is provided comprises information relating to a subcarrier on which feedback is to be provided on the basis of an Ng value. The Ng value is determined on the basis of the grouping subfield and a first bit of the reserved subfield. If the first bit is configured as 1 and the grouping subfield is configured as 0, the Ng value is determined as 8. If the first bit is configured as 1 and the grouping subfield is configured as 1, the Ng value is determined as 32.
