Method and apparatus for transmitting list of bearers in wireless communication system

A method for checking, by a second eNodeB (eNB) of a compensation cell, a list of bearers in a wireless communication system, the method comprising:

• transmitting, by the second eNB of the compensation cell, an energy saving request message to a first eNB of an energy saving cell;
• receiving, by the second eNB of the compensation cell, a list of minimum required evolved universal mobile telecommunications system (UMTS) terrestrial radio access network (E-UTRAN) radio access bearers (E-RABs) from the first eNB of the energy saving cell;
• checking, by the second eNB of the compensation cell, whether the compensation cell is able to support all E-RABs included in the list of minimum required E-RABs or not;
• determining, by the second eNB of the compensation cell, whether to turn off the energy saving cell or not based on the checking;
• and
• transmitting by the second eNB of the compensation cell a response message to the first eNB of the energy saving cell,
• wherein the response message includes an indication of whether to turn off the energy saving cell or not.
