    Abstract: A method of receiving a packet in a wireless local area network system includes receiving, from an access point (AP), a packet comprising a data field and a first signal field including a first field, a second field, and a third field, wherein the packet is generated for a single receiving station or a plurality of receiving stations; and processing the packet based on the first signal field, wherein the first field indicates a group ID of the single receiving station or the plurality of receiving stations and whether the packet is generated based on a single user transmission scheme or a multi user transmission scheme, wherein, for the single user transmission scheme, at least one pre-determined value of the first field is used to indicate that the packet is generated based on the single user transmission scheme.

    Abstract: A method of transmitting information on a modulation and coding scheme (MCS) in a wireless local area network system is provided. A responding station receives a physical layer protocol data unit (PPDU) from a requesting station, configures a MCS feedback (MFB) based on the PPDU, and transmits feedback information to the requesting station. If the MFB is configured as a response to a MFB request (MRQ) of the requesting station, the feedback information includes the configured MFB and a MFB type field indicating that the MFB is configured as a response to the MRQ of the requesting station. If the MFB is not configured as a response to the MRQ of the requesting station, the feedback information includes the configured MFB, a MFB type field indicating that the MFB is not configured as a response to the MRQ of the requesting station, and coding information indicating a PPDU coding type.

    Abstract: A method and a device for reporting a modulation and coding scheme (MCS) feedback in a wireless local area network are provided. A responding station receives, from a requesting station, a requesting Physical layer Protocol Data Unit (PPDU) for requesting a MCS feedback via a plurality of spatial streams. A recommended MCS is estimated under an assumption that the requesting station will transmit at least one first spatial stream among the plurality of spatial streams used for the requesting PPDU, The responding station transmits, to the requesting station, the MCS feedback including a recommended MCS field indicating the recommended MCS and a recommended stream field indicating a number of at least one recommended spatial stream. A number of the at least one first spatial stream used for estimating the recommended MCS is equal to the number of the at least one recommended spatial stream.
