Cells are grouped into a plurality of physical uplink control channel (PUCCH) groups comprising a primary PUCCH group and a secondary PUCCH group comprising a PUCCH secondary cell. The PUCCH secondary cell is in a first timing advance group (TAG). When a time alignment timer of the first TAG expires, the wireless device stops reception of downlink shared channel transport blocks on a first secondary cell in the secondary PUCCH group and continues reception of downlink multicast channel transport blocks on the first secondary cell. |
