METHOD AND APPARATUS FOR ANCHOR CHANNEL CONTROL

Controlling synchronization signal operation in a base station (12) operating in shared spectrum includes detecting a condition related to a current anchor channel configuration used for transmission of synchronization signal transmissions and selecting, based on the detecting, a new anchor channel configuration and communicating the new anchor channel configuration to electronic devices (14) serviced by the base station. The base station commences sending a predetermined number of synchronization signal transmissions using the current anchor channel configuration; and one of: i) sends synchronization signal transmissions using the new anchor channel configuration if the predetermined number of synchronization signal transmissions are sent on the current anchor channel configuration; or ii) aborts a change to the new anchor channel configuration if feedback is received from one of the electronic devices that the electronic device detected interference on the new anchor channel configuration before the predetermined number of synchronization signal transmissions are sent.
