18. A method for wireless communications at a user equipment (UE), comprising:
receiving, from a second cell, first control signaling indicating that the UE is to transmit, to a first cell that is deactivated, a random access message for a timing advance probing procedure;
transmitting, based at least in part on the first control signaling, the random access message to the first cell;
receiving, from a second cell, an activation command that activates the first cell and an indication of a timing advance value for the first cell generated based at least in part on the random access message; and
communicating with the first cell based at least in part on the activation command and the timing advance value.
