Title:
METHOD AND DEVICE FOR SELECTIVELY TRANSMITTING SUBCHANNEL BASED ON TARGET WAKE TIME IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/153913
Kind Code:
A1
Abstract:
A method and a device for performing an SST operation in a wireless LAN system are disclosed. A method by which a first station (STA) performs an SST operation in a wireless LAN system comprises the steps of: receiving, from a second STA, a target wake time (TWT) element including a control field and an individual TWT parameter set field; and performing the SST operation on the basis of the TWT element, wherein the control field includes a first field for indicating a format of the individual TWT parameter set field supporting a bandwidth of 320 MHz or more, and the TWT element can include a second field related to a channel width resolution for the SST operation.
