A method performed in a wireless communication device for cell scanning in a wireless communication network, wherein the wireless communication device is capable of wireless communication with at least a first Radio Access Technology, RAT, according to Narrow Band Internet of Things, NB-loT, standard, at a first carrier frequency, F1, and the wireless communication device is an loT device, wherein the method comprises: performing a cell scanning on the first carrier frequency for determining a possible access node to connect to, wherein the first carrier is the carrier the wireless communication device has been connected to before it is turned off or goes to sleep mode; 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: retrieving stored broadcast information; obtaining system deployment information for the first carrier frequency from the broadcast information; determining at least a second carrier frequency for cell scanning based on the system deployment information; and performing cell scanning on the determined at least second carrier frequency, wherein the system deployment information is related to whether the first RAT is deployed in any one of: (a) a standalone operation, wherein carrier frequencies of the first RAT are independent of a second RAT; (b) a guard band operation, wherein carrier frequencies of the first RAT are in a guard band of a second RAT; (c) an in-band operation, wherein carrier frequencies of the first RAT are within bandwidth of a second RAT. performing a cell scanning on the first carrier frequency for determining a possible access node to connect to, wherein the first carrier is the carrier the wireless communication device has been connected to before it is turned off or goes to sleep mode; 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: retrieving stored broadcast information; obtaining system deployment information for the first carrier frequency from the broadcast information; determining at least a second carrier frequency for cell scanning based on the system deployment information; and performing cell scanning on the determined at least second carrier frequency, wherein the system deployment information is related to whether the first RAT is deployed in any one of: (a) a standalone operation, wherein carrier frequencies of the first RAT are independent of a second RAT; (b) a guard band operation, wherein carrier frequencies of the first RAT are in a guard band of a second RAT; (c) an in-band operation, wherein carrier frequencies of the first RAT are within bandwidth of a second RAT. retrieving stored broadcast information; obtaining system deployment information for the first carrier frequency from the broadcast information; determining at least a second carrier frequency for cell scanning based on the system deployment information; and performing cell scanning on the determined at least second carrier frequency, wherein the system deployment information is related to whether the first RAT is deployed in any one of: (a) a standalone operation, wherein carrier frequencies of the first RAT are independent of a second RAT; (b) a guard band operation, wherein carrier frequencies of the first RAT are in a guard band of a second RAT; (c) an in-band operation, wherein carrier frequencies of the first RAT are within bandwidth of a second RAT. (a) a standalone operation, wherein carrier frequencies of the first RAT are independent of a second RAT; (b) a guard band operation, wherein carrier frequencies of the first RAT are in a guard band of a second RAT; (c) an in-band operation, wherein carrier frequencies of the first RAT are within bandwidth of a second RAT.
