MECHANISMS FOR INITIAL ACCESS TO A RADIO ACCESS NETWORK

摘要

There is provided mechanisms for initial access to a radio access network. The method is performed by a wireless device. The wireless device is configured for accessing the radio access network using at least a first cellular RAT and a second cellular RAT. The method comprises obtaining system information using a first carrier frequency and the first RAT. The system information comprises inter-frequency cell information of the second RAT. The method comprises synchronizing with the second RAT using a second carrier frequency based on the obtained system information in order to establish initial access to the radio access network. The second carrier frequency is higher than the first carrier frequency.
