Claim 7:
8. A user equipment device (UE), comprising:
a radio; and
a processor operably coupled to the radio and configured to cause the UE to:
restart a timing alignment timer (TAT) in response to a first timing advance command from a cellular network for a plurality of serving cells;
based on radio resource configuration (RRC) information from the cellular network, identify 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;
activate the plurality of configurations for the SP-CSI reports based on downlink control information (DCI) from the cellular network;
transmit 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:
deactivate the plurality of configurations for the SP-CSI reports; and
restart the TAT for the plurality of serving cells according to a second timing advance command, wherein none of the plurality of configurations for the SP-CSI reports are active upon restarting the TAT for the plurality of serving cells.
