Abstract: The present disclosure discloses a master node, a secondary node and a user equipment in a mobile communication network and communication methods thereof. According to an implementation, a method performed by a master node (MN) in a mobile communication network, comprises with receiving from a user equipment (UE), a first message including information reporting a failure of a secondary cell group (SCG) in case that a secondary node change from the source secondary node to a first target secondary node is failed and transmitting, to the source secondary node, a second message including information associated with a failure of the secondary node change, wherein the second message includes at least one of following information, an identifier of the first target secondary node where the failure of the secondary node change occurs, an identifier of the source secondary node to which the UE successfully connects before the failure of the secondary node change, and information on a type of the failure of the secondary node change.

Abstract: A method, a mission critical (MC) server, and a receiver for managing media communication in an MC system are provided. The method comprises receiving, from a sender, a request and a media stream for transmitting the media stream to one or more receivers. The request indicates a mode of transmission of the media stream. Further, the method comprises transmitting a notification message indicating a mode of reception identified based on the mode of transmission, to the one or more receivers for receiving the media stream from the sender. The mode of reception is one from among an emergency mode and a normal mode. Thereafter, the method comprises transmitting the media stream to the one or more receivers subsequent to transmission of the notification message, when the mode of reception is the emergency mode.

Abstract: An Error correction code (ECC) decoder including an input manager configured to sequentially receive a first read data including a plurality of data units read from a plurality of sectors in a memory cell array of a nonvolatile memory device, by unit of sector, a pre-decoder configured to sequentially receive the first read data and generate a respective syndrome of each of the data units, and a main decoder configured to sequentially perform a first ECC decoding on the first read data based on the respective syndrome. The input manager includes a defective sector buffer to store a data unit having a minimum expected error count from among data units on which a first ECC decoding is failed. The main decoder performs a second ECC decoding on a defective data unit stored in the defective sector buffer and receives a second read data from a selected sector corresponding to the defective data unit.

Abstract: An electronic device includes a housing, an antenna structure disposed in an inner space of the housing, a wireless communication circuit disposed in the inner space, and a first bracket. The antenna structure includes a substrate having a first substrate surface facing in a first direction and a second substrate surface facing in a second direction opposite to the first substrate surface, and a plurality of chip antennas sequentially arranged on the first substrate surface in a third direction perpendicular to the first direction. Each of the plurality of chip antennas includes an antenna element and is separated in the third direction from remaining chip antennas by separation spaces. The first bracket includes first and second protrusions that protrude in the second direction to correspond to the first substrate surface of the substrate. The protrusions are aligned, in the third direction, with the separation spaces.
