The wireless device transmits first uplink signals in the second carrier group employing a first additional carrier in the second carrier group as a timing reference carrier. The wireless device autonomously changes the timing reference carrier to a second additional carrier in the second carrier group. The second additional carrier is an active carrier different from the first additional carrier. The wireless device transmits second uplink signals in the second carrier group employing the second additional carrier as the timing reference carrier."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Timing reference in a wireless device","description":"A base station configures a first carrier group and a second carrier group in a wireless device.
