The method includes determining whether a SCC channel has started to be used by a first network. The SCC channel is a CA channel shared with at least one other network. In response to determining that the SCC channel has been started to be used by the first network, the UE determines an off duration describing a period since a previous SCC channel ON period. A given channel ON period is a continuous period of use of the given channel by the first network, The method also includes, in response to determining that the off duration is less than a minimum threshold duration, performing fine synchronization based on CRS tracking on the SCC channel using course synchronization parameters of the previous SCC channel ON period. Apparatus and computer readable media are also described."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for synchronization mechanisms on un-licensed band","description":"A method for synchronizing channels on unlicensed bands is described.
