A method for performing a sidelink transmission in a wireless communication system and a device are disclosed in the present specification. In detail, in the present specification, a method for performing a sidelink transmission in a wireless communication system, the method performed by a user equipment (UE) includes receiving, from a base station, a sidelink grant to be used for scheduling of the sidelink transmission, wherein the sidelink grant includes control information indicating an offset of a specific subframe associated with the sidelink grant; determining the specific subframe in consideration of a value indicated by the control information; and performing the sidelink transmission in the specific subframe.

A base station may utilize frequency division multiplexing (FDM) techniques to signal synchronization signal (SS) blocks and downlink transmissions (e.g., data/control transmissions). The base station may configure a configuration for a bandwidth part (BWP) of a carrier for downlink transmissions. The BWP configuration may include a transmission attribute (e.g., a subcarrier spacing (SCS)) for downlink transmissions within the BWP. The base station may transmit a grant for a downlink transmission to a user equipment (UE). In some cases, the downlink transmission may be scheduled for a set of resources that overlap in time with a SS block for the carrier. The base station may transmit downlink transmissions within the BWP using transmission attributes configured for the BWP and/or using SS block transmission attributes, depending on capabilities of the UE, on whether the time resources of the downlink transmission that are FDMed with the SS block, etc.

A cell site of a cellular communication network may have both a Long-Term Evolution (LTE) base station and a New Radio (NR) base station to support NR Standalone connectivity and Non-Standalone (NSA) dual connectivity. The NR base station broadcasts system information from which a cellular device can determine relative service qualities of a NR Standalone connection and an NSA connection. The cellular device receives these qualities and compares them to determine whether to initially attach to the LTE base station or to the NR base station. Similarly, during cell reselection, the cellular device receives service quality information from a target LTE base station so that the cellular device can determine whether to attach to the target LTE base station or to an associated NR base station.

Aspects of the present disclosure describe a computer implemented method for the transfer of sensor data on dynamic software defined network (SDN) controlled optical network.

A method for receiving a downlink signal in a wireless communication system according to an embodiment of the present invention is performed by a terminal, and may comprise the steps of: receiving, from a base station, a dynamic change configuration into a predetermined transmission scheme related to a short transmission time interval (sTTI)-based downlink operation; when the dynamic change configuration is received, detecting a downlink control information format including a field related to the dynamic change; and when a value of the field indicates the predetermined transmission scheme, receiving a signal on a downlink data channel according to the predetermined transmission scheme.

The present disclosure relates to methods and devices for a handover procedure which may include a user equipment (UE), first base station, and a second base station. In one aspect, the UE can receive an indication to handover from the first base station to the second base station. The UE may then establish a connection with the second base station. In another aspect, the UE can maintain a connection with the first base station over a period of time during the handover. The UE can also communicate with the first base station and the second base station during the period of time based on a time division multiplexing (TDM) pattern. The TDM pattern can comprise a pattern of subframes for communicating with the first and second base station. In another aspect, the UE can release the connection with the first base station at the end of the period of time.

A technique capable of allowing a reception side to easily select components is provided. A transport stream in which a first transport packet including predetermined components and a second transport packet including signaling information related to the predetermined components are time-division multiplexed is transmitted via a predetermined transport path. Component selection information is inserted in the second transport packet. The component selection information includes information on a selective layer in which static selection is performed, information on a composite layer in which composition is performed, and information on an adaptive layer in which dynamic switching is performed, and these layers being arranged in that order from top to bottom. The acquisition destination information of a component which is a target of adaptive switching among the components selectable in the adaptive layer is information that designates specific information location of a metafile having data stream acquisition information for adaptive streaming.
