Abstract: Disclosed is a method for transmitting a frame of a wireless communication system. A non-AP STA receives a beacon frame comprising a request type field from an AP and can receive a downlink frame or transmit an uplink frame in accordance with a specific field value included in the beacon frame. Here, the request type field comprises a specific field for indicating a target wake time (TWT) for a low latency operation, and, if the value of the specific field is set as a first specific value, a broadcast TWT service period (SP) is a TWT SP for the low latency operation.

Abstract: Disclosed is a method by which a multi-link device (MLD) of a wireless communication system transmits a frame. The MLD transmits a request frame for mapping between a traffic identifier (TID) and a link, and the request frame can include: first mapping information for establishing a mapping relationship between one or more TIDs from among a plurality of TIDs and one or more links; and information related to the number of the one or more TIDs for which mapping with the one or more links is requested. Thereafter, the MLD can receive a response frame in response to the request frame, and first remaining TIDs that exclude the one or more TIDs from among the plurality of TIDs maintain, to be valid, a previously established mapping relationship with a link, or a default mapping relationship is applied, and, for the first remaining TIDs, a mapping relationship with a specific link may not be indicated by the first mapping information.

Abstract: Disclosed is a method for receiving data by a terminal in a wireless communication system. The terminal may receive a physical protocol data unit (physical layer protocol data unit: PPDU) from an access point (APAP) and decode the received PPDU. The PPDU may include a universal signal (U-SIG) field and an extremely high throughput (EHT)-SIG field including at least one content channel, and the U-SIG field may include a bandwidth field indicating the total bandwidth via which the PPDU is transmitted. The total bandwidth is divided into at least one segment, and at least one of field among same fields includes same information except for a resource unit allocation (RU allocation) field between a first content channel and a second content channel in the same segment among the at least one segment when the at least one content channel is composed of a first content channel and a second content channel.
