Abstract
Methods, apparatuses, and systems for wireless communications are described. Uplink signals may be time aligned based on different synchronization signals as a timing reference for different carrier groups. A base station may send, to a wireless device, a time alignment command comprising: an indication of a carrier group index, and a time adjustment value. Based on the time alignment command, the wireless device may send second uplink signals.

A method comprising:
- transmitting, by a base station, at least one radio resource control message associated with configuration of a plurality of carrier groups, wherein the plurality of carrier groups comprises:
- a primary carrier group;
- and
- a secondary carrier group, and
- wherein uplink signals of the plurality of carrier groups are time aligned based on different timing references for different carrier groups of the plurality of carrier groups;
- transmitting, to a wireless device, a time alignment command comprising:
- an identity of a carrier group of the plurality of carrier groups;
- and
- a time adjustment value;
- and
- receiving, via at least one carrier of the carrier group and based on the time alignment command, an uplink signal.

A base station comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, configure the base station to:
- transmit at least one radio resource control message associated with configuration of a plurality of carrier groups, wherein the plurality of carrier groups comprises:
- a primary carrier group;
- and
- a secondary carrier group, and
- wherein uplink signals of the plurality of carrier groups are time aligned based on different timing references for different carrier groups of the plurality of carrier groups;
- transmit, to a wireless device, a time alignment command comprising:
- an identity of a carrier group of the plurality of carrier groups;
- and
- a time adjustment value;
- and
- receive, via at least one carrier of the carrier group and based on the time alignment command, an uplink signal.
