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.

Abstract: Disclosed herein is a nickel-based heat-resistant material with improved cyclic oxidation properties. The nickel-based heat-resistant material containing gadolinium (Gd) according to the present invention is capable of suppressing the de-lamination of an oxide layer and increasing stability of the oxide layer, thereby forming an overall thin and uniform oxide layer, and has an advantage in that the formation of a nitride may be suppressed since nitrogen is prevented from penetrating through the oxide layer. In addition, due to the slow oxidation rate, there is an advantage in that an Al depletion layer (a ?? denuded zone) by the formation of an oxide layer may be formed to be very thin compared to that of a specimen having no gadolinium added.
