Abstract

One embodiment of the present invention relates to a method for transmitting a signal of a station (STA) operable in a power saving mode in a wireless communication system, and the method for transmitting a signal comprises a step of transmitting a PS-Poll frame and/or a trigger frame according to a first time period, wherein an integrated scaling factor is applied to the first time period, and the integrated scaling factor is also commonly applied to a second time period in which the STA can omit frame transmission by maintaining an association state with an access point (AP).

Claims13

Dependent claims

A method for transmitting a signal of a station (STA) operable in a power saving mode in a wireless communication system, the method comprising:

determining a first time period by applying a scaling factor to a first time interval related to the power saving mode, and
transmitting at least one of a PS-Poll frame and a trigger frame according to the determined first time period,
wherein the scaling factor applied to the first time interval is commonly applied to a second time interval and a third time interval related to the power saving mode, when the STA determines a second time period from the second time interval and a third time period from the third time interval.

Dependencies are inferred from the claim text.
