Abstract
A base station transmits control message(s) comprising media access control dedicated parameters. The media access control dedicated parameters comprise a primary time alignment timer value for a primary cell group and a sequence of at least one element. Each element comprises a secondary time alignment timer value and a secondary cell group index. The secondary time alignment timer value is associated with the cell group identified by the secondary cell group index. Each secondary time alignment timer value is selected from a finite set of predetermined values.
