Abstract: A method of reporting a channel state, which is reported by a terminal configured to transmit and receive data while hopping in a unit of the specific number of resource blocks (RBs) in a wireless communication system, includes receiving a random access response including an aperiodic channel state report request in response to a transmitted random access preamble, calculating channel state information according to the aperiodic channel state report request in consideration of the number of repetitive transmissions for the terminal, and reporting the calculated channel state information to a base station. In this case, the number of repetitive transmissions for the terminal may be determined by a predetermined or signaled value.

Abstract: A method and an apparatus for wireless communication with dual connectivity are described. The apparatus supports dual connectivity with a first cell and a second cell and the apparatus comprises a radio frequency (RF) and a processor operatively coupled to the RF unit. The second cell is an overlaid virtual cell which is formed by collaborating the first cell and cell ID of the second cell is different from physical cell ID of the first cell when the processor uses primary synchronization signal (PSS), secondary synchronization signal (SSS) or cell-specific common reference signal (CRS) as synchronization signal for the second cell.
