Abstract: A apparatus and a method thereof for managing access nodes for a low-latency service in a multi-radio multi-connectivity network are proposed. The method of operating user equipment (UE) in a wireless communication system includes a process of scanning a plurality of secondary nodes (SNs) where radio signals are measured around the UE, a process of transmitting a scanning result to a master node (MN), a process of receiving information about an SN group from the MN, a process of accessing an active SN on the basis of the information about the SN group, and a process of transmitting a message for establishing and modifying a protocol data unit (PDU) session to a core network (CN).

IPC: H04W74/08
Abstract: Provided is a method for transmitting, by a transmitter, a first data having periodicity through a channel of an unlicensed band:The transmitter adjusts at least one of transmission timing of the first data and clear channel assessment (CCA) timing for the channel to occupy the channel. The transmitter determines whether the channel may be occupied by performing a CCA on the channel at the CCA timing. The transmitter transmits the first data through the channel at the transmission timing of the first data, when it is determined that the channel may be occupied.
