Abstract: Disclosed is a method by which a terminal transmits a physical uplink shared channel (PUSCH) to a base station in a wireless communication system. The terminal can receive, from the base station, configuration information for allocating a resource for transmitting a transport block (TB) through the PUSCH, and map the TB to a plurality of slots constituting the resource on the basis of the configuration information. Thereafter, the terminal can transmit the TB on the plurality of slots through the PUSCH.

Abstract: A multi-link device using a plurality of links is disclosed. A processor receives, in any one link of the plurality of links, a first physical layer protocol data unit (PPDU) including access category (AC) constraint signaling and a reverse direction (RD) grant from a station which is a transmission opportunity (TXOP) holder or a service period (SP) source, and transmits, in the any one link, a second PPDU to the station in response to the first PPDU on the basis of the AC constraint signaling. The AC constraint signaling indicates whether a traffic identifier (TID) or AC of a frame included in the second PPDU is constrained.

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.
