Timing Advance Group of a Control Channel in a Wireless Device

A wireless device comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
• receive configuration parameters of cells, wherein:
• the cells are grouped into timing advance groups (TAGs) comprising a secondary TAG;
• and
• the cells are grouped into physical uplink control channel (PUCCH) groups comprising a secondary PUCCH group comprising:
• a PUCCH secondary cell with a secondary PUCCH, wherein the PUCCH secondary cell is in the secondary TAG;
• and
• a first secondary cell;
• and
• in response to a time alignment timer of the secondary TAG expiring or stopping:
• stop transmission of positive or negative acknowledgement for one or more HARQ processes of an activated cell in the secondary PUCCH group;
• stop reception of downlink shared channel transport blocks via the first secondary cell;
• and
• continue reception of downlink multicast channel transport blocks via the first secondary cell.
