The PUCCH groups comprise a secondary PUCCH group. The secondary PUCCH group comprises: a PUCCH secondary cell, with a secondary PUCCH, of a secondary timing advance group (TAG); and a first secondary cell. In response to a time alignment timer of the secondary TAG expiring or stopping the wireless device: stops transmission of acknowledgements for packets of the first secondary cell; stops reception of downlink shared channel packets via the first secondary cell; and continues reception of downlink multicast channel packets via the first secondary cell."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Responding to a time alignment timer of a secondary timing advance group","description":"A wireless device receives configuration parameters of cells grouped into physical uplink control channel (PUCCH) groups.
