One method may include receiving, at a first base station, at least one clear channel assessment (CCA)-exempt transmission (CET) indicating timing information of at least a second base station over a shared spectrum. A timing of the first base station may be adjusted based on the received timing information of the second base station. Another method of wireless communication may include identifying a CCA slot assigned to a first base station for a frame, which may be associated with time synchronization, of a shared spectrum. A CCA may be performed at the identified CCA slot for the frame. When the CCA is successful, a first timing information of the first base station may be selectively transmitted during the frame. When the CCA is unsuccessful, a second timing information of a second base station may be listened for during the frame."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of synchronization within an LTE/LTE-A system in unlicensed spectrum","description":"Methods, systems, and devices are described for wireless communication.
