Abstract: A method and apparatus for low latency communication in a wireless LAN support an enhanced multi-link single radio (eMLSR) operation. A method of operating a station (STA) includes steps of: identifying, by a processor of the station, a restricted target wake time (rTWT) service period (SP) configured by an access point (AP); and receiving, from the AP, a data frame without reception of an initial control frame of the AP within the rTWT SP. A period receivable on multiple spatial streams in a low latency communication service period may be clearly configured, and an eMLSR STA may transmit a frame in the corresponding period. Also, the eMLSR STA may receive the data frame without the reception of the initial control frame of the AP. Accordingly, low latency demands for frame transmission may be satisfied, and the frame may be transmitted at a high speed.
