主权项

1. A method for a base station of a communication system for supporting multi-carriers to manage the multi-carriers, comprising:
selecting a carrier, the selected carrier being the carrier, from among the supported multi-carriers, that is determined to be usable in common by the greatest number of terminals among a first terminal that is currently attempting to enter a sleep window and a plurality of second terminals having entered the sleep window; requesting the first terminal to change a primary carrier from a current primary carrier to the selected carrier; and transmitting a control message to the first terminal through the primary carrier that is changed to be the selected carrier for the sleep window.
