Abstract:
An ACK signal processing method that can be used in a wireless LAN system is proposed. Various information that can be used for a downlink MU PPDU for multiple receiving stations may be proposed, and, for example, in order to omit the re-transmission of the related art, information requesting an ACK or Block ACK corresponding to previously transmitted data may be included. If an immediate acknowledgement (ACK) frame fails to be received after the MU-PPDU is transmitted from the AP, a Block ACK may be requested. In this case, while a Block ACK is requested, a radio resource through which a Block ACK is delivered may be allocated.

Claim (Index 5):
The method of  claim 1 , wherein the first PPDU includes a legacy field, a high efficient signal (HE-SIG) field, and a data field, wherein the legacy field includes a legacy short training field (L-STF), a legacy long training field (L-LTF), a legacy signal (L-SIG) field, wherein the HE-SIG field indicates downlink resources for the multiple receiving stations, wherein a first subcarrier spacing is applied to the legacy field and the HE-SIG field and a second subcarrier spacing is applied to the data field, wherein the first subcarrier spacing is four times greater than the second subcarrier spacing.
