Abstract: The present invention relates to a method and apparatus for indicating a cell splitting pattern to a neighboring base station. A base station may perform cell splitting, and transmit, to the neighboring base station, coverage information representing the current shape of the split cells of the base station, determined by the cell splitting. In addition, the base station may further transmit, to the neighboring base station, index information indicating the current cell splitting pattern preconfigured between the base station and the neighboring base station. The neighboring base station may apply a set of mobility robustness optimization (MRO) parameters on the basis of the received coverage information.

Abstract: A method and apparatus for performing trace recording in a wireless communication system is provided. It is assumed that an evolved NodeB (eNB) is shared by a first operator and a second operator. The UE receives an indication, which allows collecting minimization of drive tests (MDT) logs of a user equipment (UE) of the second operator, from a mobility management entity (MME) of the second operator. Upon collecting the MDT logs, the UE transmits a trace record based on the collected MDT logs to a trace collection entity (TCE) of the first operator.
