Abstract: A method performed in a wireless local area network (LAN) system according to various embodiments is associated with a first station (STA) supporting multi-links comprising first and second links. A control field associated with an operating mode (OM) of the first STA can be associated with the on-off of the first link and/or the second link. The first and second links can each be a channel for various bandwidths defined in, for example, 2.4 GHz band, 5 GHz band and 6 GHz band. The first and second links can belong to the same or different bands. On-off information relating to each link can be formed on the basis of information such as an index or a control field bitmap associated with the operating mode.

Abstract: Disclosed is a signal processing method for changing an operating mode for transmitting a PPDU in a wireless LAN system. Specifically, a first station transmits, to a second station, the number of spatial streams supported by the first station, and a first instructional information instructing a change of the operating mode indicating a channel bandwidth. The first station applies the first instructional information after receiving an ACK therefor. The first instructional information comprises an operating mode indicator for indicating whether the operating mode is a receive operating mode (ROM) or a transmit operating mode (TOM).

Abstract: Provided are a method and apparatus for transmitting/receiving a signal based on a power saving (PS) mode in a wireless local area network (WLAN) system. Specifically, a first station (STA) determines the PS mode in a time division duplex (TDD)-based service period (SP), and transmit the signal to the second STA or receive the signal from the second STA based on the PS mode. The SP includes a plurality of TDD slots. The plurality of TDD slots include an unassigned TDD slot, an assigned Tx TDD slot, and an assigned Rx TDD slot. In the unassigned TDD slot, a PS mode of the first STA is determined as a doze state, and a PS mode of the second STA is determined an awake or doze state. In the assigned Rx TDD slot, the PS mode of the first STA is determined as the awake state, and the PS mode of the second STA is determined as the awake state. In the assigned Tx TDD slot, the PS mode of the first STA is determined as the awake or doze state, and the PS mode of the second STA is determined as the awake state.

Abstract: Disclosed is a method for reducing power consumption by a station (STA) in a mobile communication system. When a trigger frame including a common information field and a user information field is received from an access point (AP), the user information field indicates different information in the case where an association ID (AID) subfield of the user information field has a first value indicating resource allocation for random access and in the case where the AID subfield of the user information field has a value other than the first value. In addition, when the AID subfield has the first value, the user information field includes information indicating whether a resource for random access is allocated, and the STA may transition to a doze state on the basis of the information indicating whether a resource for random access is allocated.
