A method for adjusting a timing of a wireless communication in a wireless communication system configured for carrier aggregation, comprising: communicating a random access preamble in an uplink from a user equipment, UE, (202; 302; 402; 1202; 1302) to an eNodeB (214; 314; 414; 1220; 1320) via a Primary Cell, PCell, associated with a selected component carrier of the carrier aggregation; receiving a Random Access Response, RAR, at the UE (202; 302; 402; 1202; 1302) from the eNodeB (214; 314; 414; 1220; 1320) for the PCell, wherein the RAR contains an 11-bit timing advance adjustment in a Medium Access Control, MAC, RAR and a Cell Radio Network Temporary Identifier, C-RNTI, for the PCell, the 11-bit timing advance adjustment instructing the UE (202; 302; 402; 1202; 1302) to adjust a timing of a PCell wireless communication; receiving a request at the UE (202; 302; 402; 1202; 1302) to adjust a timing of a Secondary Cell, SCell, wireless communication associated with a second component carrier of the carrier aggregation; communicating a random access preamble in an uplink from the UE (202; 302; 402; 1202; 1302) to the eNodeB (214; 314; 414; 1220; 1320) via the SCell; receiving an RAR at the UE (202; 302; 402; 1202; 1302) from the eNodeB (214; 314; 414; 1220; 1320) for the SCell, wherein the RAR contains an 11-bit timing advance adjustment in a Medium Access Control, MAC, RAR, the 11-bit timing advance adjustment instructing the UE (202; 302; 402; 1202; 1302) to adjust a timing of the SCell wireless communication but not receiving a Cell Radio Network Temporary Identifier, C-RNTI, for the SCell; and maintaining a timing advance adjustment at the SCell by receiving a timing advance Medium Access Control, MAC, Control Element that contains a minor timing advance adjustment instructing the UE (202; 302; 402; 1202; 1302) to adjust a timing of the SCell wireless communication. communicating a random access preamble in an uplink from a user equipment, UE, (202; 302; 402; 1202; 1302) to an eNodeB (214; 314; 414; 1220; 1320) via a Primary Cell, PCell, associated with a selected component carrier of the carrier aggregation; receiving a Random Access Response, RAR, at the UE (202; 302; 402; 1202; 1302) from the eNodeB (214; 314; 414; 1220; 1320) for the PCell, wherein the RAR contains an 11-bit timing advance adjustment in a Medium Access Control, MAC, RAR and a Cell Radio Network Temporary Identifier, C-RNTI, for the PCell, the 11-bit timing advance adjustment instructing the UE (202; 302; 402; 1202; 1302) to adjust a timing of a PCell wireless communication; receiving a request at the UE (202; 302; 402; 1202; 1302) to adjust a timing of a Secondary Cell, SCell, wireless communication associated with a second component carrier of the carrier aggregation; communicating a random access preamble in an uplink from the UE (202; 302; 402; 1202; 1302) to the eNodeB (214; 314; 414; 1220; 1320) via the SCell; receiving an RAR at the UE (202; 302; 402; 1202; 1302) from the eNodeB (214; 314; 414; 1220; 1320) for the SCell, wherein the RAR contains an 11-bit timing advance adjustment in a Medium Access Control, MAC, RAR, the 11-bit timing advance adjustment instructing the UE (202; 302; 402; 1202; 1302) to adjust a timing of the SCell wireless communication but not receiving a Cell Radio Network Temporary Identifier, C-RNTI, for the SCell; and maintaining a timing advance adjustment at the SCell by receiving a timing advance Medium Access Control, MAC, Control Element that contains a minor timing advance adjustment instructing the UE (202; 302; 402; 1202; 1302) to adjust a timing of the SCell wireless communication.
