Abstract: A method for receiving downlink data by the terminal in a wireless communication system, includes receiving, from a base station, downlink control information for scheduling a short physical downlink shared channel (sPDSCH) on a short physical downlink control channel (sPDCCH), and receiving, from the base station, downlink data on the sPDSCH based on the downlink control information. Here, the sPDCCH and the sPDSCH are based on a first transmission time interval (TTI)-based radio frame structure, wherein the first TTI-based radio frame structure is shorter in time than a second TTI-based radio frame structure related to (i) a physical downlink shared channel (PDSCH) and (ii) a physical downlink control channel (PDCCH). Further, a number of resource element groups (REGs) consisting of a control channel element (CCE) related to the sPDCCH is smaller than a number of resource element groups (REGs) composed of a CCE related to the PDCCH.

Abstract: The present disclosure provides a method and apparatus for performing an operation related to a Radio Link Failure (RLF) in a wireless communication system. Particularly, the method performed by a user equipment (UE) includes monitoring a radio link state of a serving base station (BS); detecting a physical layer problem; transmitting a specific random access preamble related to the RLF to one or more neighboring BSs through a specific Physical Random Access Channel (PRACH) resource; receiving a random access response from the one or more neighboring BSs; determining a neighboring BS to which an additional RRC connection is to be configured based on the received random access response; and configuring an RRC connection with the determined neighboring BS, wherein the specific PRACH resource is a common PRACH resource that is separately configured to transmit the specific random access preamble, thereby preventing the Link Outage phenomenon of the UE for a specific service.

Abstract: Provided is a method for receiving system information by a terminal in a cloud wireless communication system including one or more baseband units (BBUs) and remote radio units (RRUs), the one or more RRUs being connected to a particular BBU among the BBUs to provide a direct service to the terminal via one or more cells. The method is characterized in that the terminal receives, from the network, an identifier that can understand whether there are any changes in the BBU, the RRU, and the cell, and through the received identifier understands whether there are one or more changes among the BBU, the RRU, and the cell, and selectively receives, from the network, the only system information required for any one among the BBU change, the RRU change, and the cell change.
