METHOD FOR PERFORMING A COOPERATIVE OPERATION BETWEEN HETEROGENEOUS NETWORKS AND DEVICE FOR SAME
First Claim
1. A method of detecting a base station by a user equipment in a wireless communication system that performs a cooperative operation between heterogeneous networks, the method comprising:
- receiving at least one interworking signal (IWS) from at least one first type base station through a transmission band of a second type base station;
acquiring cell identifier (ID) information from the received at least one IWS; and
scanning a base station, which uses the same wireless communication scheme as that of the at least one first type base station based on the acquired cell ID information,wherein the first type base station and the second type base station use different wireless communication schemes or wireless access schemes from each other.

Abstract
The present invention relates to a method for performing a cooperative operation between heterogeneous networks and a device for same. A method for a first type base station to perform a cooperative operation between heterogeneous networks in a wireless communication system includes receiving a downlink synchronization channel from at least one second type base station; obtaining an identifier (ID) of the second type base station by using the received downlink synchronization channel; and transmitting at least one of a channel number and a bandwidth of a center frequency of the first type base station and the cell ID of the second type base station to a server. The first type base station and the second type base station use different wireless communication methods or wireless access methods.
