Title: COMMUNICATION DEVICE AND METHOD FOR CELL SEARCH
Abstract:
A wireless communication device and method therein for cell scanning in a wireless communication networks are disclosed. The wireless communication device is capable of wireless communication with at least a first Radio Access Technology, RAT, at a first carrier frequency. The wireless communication device performs (410) a cell scanning on the first carrier frequency for determining a possible access node to connect to. When no synchronization signal on the first frequency is detected, or when a synchronization signal on the first frequency is detected but connection establishment procedure to the access node broadcasting the detected synchronization signal is unsuccessful, the wireless communication device obtains (420) system deployment information for the first carrier frequency and determines (430) at least a second carrier frequency for cell scanning based on the system deployment information. The wireless communication device then performs (440) cell scanning on the determined at least second carrier frequency.
