Carrier aggregation radio configuration

Abstract

A base station transmits to a wireless device at least one first message comprising configuration parameters of a plurality of cells. The plurality of cells is grouped into a plurality of physical uplink control channel (PUCCH) groups comprising a primary PUCCH group comprising a primary cell with a primary PUCCH received by the base station and a secondary PUCCH group. The secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH received by the base station and one or more other secondary cells. The base station detects a radio link issue with the PUCCH secondary cell. The base station transmits at least one media access control (MAC) command configured to deactivate at least one of the one or more other secondary cells in the secondary PUCCH group in response to the radio link issue with the PUCCH secondary cell.
