POWER SAVING MODE OPERATION METHOD IN WIRELESS LAN SYSTEM, AND APPARATUS FOR SAME
First Claim
1. A method of operating in a power saving (PS) mode by a station (STA) in a wireless local area network (LAN) system supporting a high efficiency physical layer protocol data unit (HE PPDU), the method comprising:
- receiving a trigger frame for allocating a resource for transmission of an uplink multi-user (UL MU) PPDU; and
determining whether to transition to a doze state based on the trigger frame,wherein, when the resource is not allocated to the STA through the trigger frame, the STA transit ions to the doze state during a time duration determined based on a value of indicator information of the trigger frame.

Abstract
A method for a station (STA) to operate in a power saving (PS) mode in a wireless LAN system that supports a high efficiency physical layer protocol data unit (HE PPDU), in one embodiment of the present invention, comprises the steps of: receiving a trigger frame which assigns a resource for transmission of an uplink multi-user (UL MU) PPDU; and determining whether to perform transition to a doze state on the basis of the trigger frame, wherein when the resource is not assigned to the STA through the trigger frame, the STA determines to perform transition to a doze state during a time period determined on the basis of an indicator information value of the trigger frame.

13. A station (STA) for operating in a power saving (PS) mode in a wireless local area network (LAN) system supporting a high efficiency physical layer protocol data unit (HE PPDU), the STA comprising:
-
a receiver configured to receive a trigger frame for allocating a resource for transmission of an uplink multi-user (UL MU) PPDU; and a processor configured to determine whether the STA should transition to a doze state based on the trigger frame, wherein, when the resource is not allocated to the STA through the trigger frame, the processor determines that the STA should transition to the doze state during a time duration determined based on a value of indicator information of the trigger frame. - View Dependent Claims (14, 15)
