Abstract: Methods and apparatus are provided for transmitting and receiving control information, for interference detection by a User Equipment (UE), in a wireless communication system. A base station determines whether the UE supports interference-aware detection. When the UE supports interference-aware detection, the control information is generated that includes interference signal modulation scheme information and demodulation reference signal measurement information. The control information is transmitted to the UE. The interference at the UE is measured based on the received control information.

A user equipment (UE) is required to select a dedicated core network so as to receive a suitable service. In a method for transmitting and receiving a signal, an enhanced Node B (eNB) of a mobile communication system transmits a first request message to a first mobile management entity (MME), receives a reroute command message based on the first request message from the first MME, and transmits a second message to a second MME based on the reroute command message. Herein, the reroute command message contains the first request message, at least one MME identifier, and a UE identifier.
