Method and apparatus for reselecting a cell in heterogeneous networks in a wireless communication system

A method for supporting a cell reselection by a base station in a wireless communication system, the method comprising:

• generating system information on an inter radio access technology (RAT) cell reselection;
• and
• transmitting, to a terminal, the generated system information,
• wherein the terminal receives the system information and determines whether a quality value based cell reselection is supported if the system information includes a quality value for a cell reselection, and
• wherein the cell reselection is performed by the terminal based on the determination.

A base station for supporting a cell reselection in a wireless communication system, the base station comprising:

• a transceiver configured to transmit and receive signals;
• and
• a controller coupled with the transceiver and configured to generate system information on an inter radio access technology (RAT) cell reselection and to transmit the generated system information to a terminal,
• wherein the terminal receives the system information and determines whether a quality value based cell reselection is supported if the system information includes a quality value for a cell reselection, and
• wherein the cell reselection is performed by the terminal based on the determination.
