Abstract: Provided is a method for generating inter-cell information for inter-cell interference removal in a wireless communication system. A method by which a terminal removes inter-cell interference comprises the steps of: receiving a signal from a serving cell and a neighboring cell adjacent to the serving cell; identifying the priority of the serving cell for feedback of channel information on the basis of an identifier of the cell and a resource block; identifying whether there is feedback of channel information on the signal received on the basis of the priority; and transmitting the channel information to a base station of the serving cell according to the identification of whether there is feedback.

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.

Specifically, groups are set by grouping a first configuration and a second configuration which arrange at least one downlink symbol and at least one uplink symbol in a subframe unit. The first configuration and the second configuration are configured in a manner that the downlink symbol and the uplink symbol do not overlap with each other in a particular symbol interval. Information indicative of a group is transmitted to a terminal for at least one subframe from among the plurality of subframes. Information indicative of a configuration to be used in the terminal of the first configuration and the second configuration in a group with respect to at least one subframe is transmitted to the terminal.
