METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA IN A WIRELESS COMMUNICATION SYSTEM

摘要

A method for and apparatus for transmitting and receiving data in a wireless communication system supporting multiple carriers is provided. A wireless device determines that a radio link failure (RLF) or a switch trigger condition is occurred for a cell among the multiple carriers, herein the multiple carriers each is set to a cell each, reconfigures an enhanced Physical Downlink Control Channel (ePDCCH) set of the cell that the RLF or the switch trigger is occurred, and determines whether cells of the multiple carriers each is on or off according to the reconfiguring. Thus, more efficient and accurate cell planning schemes are provided to transmit between the small cells and the UE to support inter-cell interference reduction and carrier extensions.
