Abstract
A base station transmits a message assigning each secondary cell to a cell group. The message comprises dedicated parameters for a secondary cell. If the dedicated parameters comprise a cell group index for the secondary cell, the secondary cell is assigned to a secondary cell group. Otherwise, the secondary cell is assigned to the primary cell group. The message comprises MAC dedicated parameters comprising a sequence of at least one information element. Each information element comprises a first cell group index of a first secondary cell group and a corresponding time alignment timer value.
