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.
Claims20
A method comprising:
- transmitting, by a base station, at least one control message comprising:
- configuration parameters of a plurality of cells grouped into a plurality of cell groups comprising a primary cell group and at least one secondary cell group;
- and
- a plurality of media access control (MAC) dedicated parameters comprising:
- a primary time alignment timer value for the primary cell group;
- and
- a sequence of at least one element, an element in the at least one element comprising one secondary time alignment timer value and one secondary cell group index for a secondary cell group, wherein the one secondary time alignment timer value is associated with the secondary cell group identified by the one secondary cell group index, wherein the one secondary time alignment timer value is selected from a finite set of predetermined values;
- transmitting a timing advance command comprising:
- a time adjustment value;
- and
- a cell group index;
- and
- starting or restarting a first time alignment timer corresponding to a cell group identified by the cell group index.
