Claim 14:
15. A method, comprising:
at a cellular network:
transmitting, to a user equipment device (UE), a first timing advance command for restarting a timing alignment timer (TAT) for a plurality of serving cells;
transmitting, to the UE, radio resource configuration (RRC) information for a plurality of configurations for semi-persistent (SP) channel state information (CSI) reports for a physical uplink shared channel (PUSCH), wherein respective configurations of the plurality of configurations for the SP-CSI reports correspond to respective serving cells of the plurality of serving cells;
transmitting, to the UE, downlink control information (DCI) to activate the plurality of configurations for the SP-CSI reports;
receiving, from the UE, one or more SP-CSI reports using the PUSCH according to the plurality of configurations for the SP-CSI reports; and
in response to expiration of the TAT:
deactivating the plurality of configurations for the SP-CSI reports; and
transmitting, to the UE, a second timing advance command for restarting the TAT for the plurality of serving cells, wherein none of the plurality of configurations for the SP-CSI reports are active upon restarting the TAT for the plurality of serving cells.
