Abstract:
A method and apparatus for synchronizing a system clock with a serving cell (102) associated with a first radio access technology and monitoring an adjacent cell (104) associated with a second radio access technology is provided. A communication device (100) includes a first synchronization device (205) capable of synchronization with the serving cell (102) and a second synchronization device (206) capable of independently synchronizing with the adjacent cell (104). The first synchronization device (205) and second synchronization device (206) include independent frequency correction modules (207,208). Thus, the second frequency synchronization device (206) may be corrected per the adjacent cell (104) while the first synchronization device (205) remains synchronized with the serving cell (102). Thus, the same corrected system clock may be used between two radio access technologies.
