Maintenance of multiple timing advance groups
A wireless device may receive one or more messages indicating at least two timing advance groups (TAGs) for a cell, wherein each TAG of the at least two TAGs is associated with a respective transmission configuration indicator (TCI) state. A wireless device may receive downlink control information (DCI). The DCI may indicate a semi-persistent scheduling (SPS) deactivation and an uplink resource of a hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback. The wireless device may indicate, to a physical layer of the wireless device, a positive acknowledgement for the SPS deactivation in response to a time alignment timer of a TAG, among the at least two TAGs and associated with a TCI state used for transmitting the HARQ-ACK feedback, being running. The wireless device may transmit, via the cell and based on the TCI state, the HARQ-ACK feedback comprising the positive acknowledgement.

9. The method of claim 8 , wherein the one or more messages are one or more radio resource control (RRC) messages.
10. The method of claim 8 , wherein the one or more messages further indicate one or more configured downlink assignments for SPS physical downlink shared channel (PDSCH) receptions.
11. The method of claim 10 , further comprising clearing the one or more configured downlink assignments for SPS PDSCH receptions based on the receiving the DCI indicating the SPS deactivation.
12. The method of claim 8 , wherein the HARQ-ACK feedback is transmitted based on a timing advance value associated with the TAG.
13. The method of claim 8 , wherein:
the time alignment timer of the TAG is a first time alignment timer of a first TAG of the at least two TAGs; and
the indicating the positive acknowledgement to the physical layer is:
in response to the first time alignment timer of the first TAG being running; and
regardless of whether a second time alignment timer of a second TAG of the at least two TAGs is running or not running.
14. The method of claim 8 , wherein the one or more messages indicate:
a first control resource set (coreset) pool index for one or more first coresets of the cell; and
a second coreset pool index for one or more second coresets of the cell.
15. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a wireless device, cause the wireless device to:
