Timing advance management and uplink transmit power prioritization for candidate cells

An apparatus for wireless communication at a user equipment (UE), comprising:

• one or more memories;
• and
• one or more processors coupled to the one or more memories, the one or more processors individually or collectively configured to:
• identify a physical random access channel (PRACH) transmission associated with a candidate cell;
• and
• transmit the PRACH transmission on the candidate cell based at least in part on a UE transmit power prioritization rule, wherein the UE transmit power prioritization rule defines a UE transmit power prioritization for a serving cell and the candidate cell.

A method of wireless communication performed by a user equipment (UE), comprising:

• transmitting, to a plurality of candidate cells, a plurality of physical random access channel (PRACH) transmissions based at least in part on one or more physical downlink control channel (PDCCH) orders with random access responses (RARs);
• determining, via a plurality of timing advance (TA) commands, a plurality of TA values for the plurality of candidate cells, respectively;
• selecting, from the plurality of TA values, a quantity of TA values based at least in part on a capability of the UE, wherein the quantity of TA values corresponds to a quantity of candidate cells, of the plurality of candidate cells;
• and
• maintaining the quantity of TA values for the quantity of candidate cells.
