Carrier prioritization for tune-away

An apparatus for performing a tune-away from a first radio access technology (RAT) to a second RAT, comprising:

• a memory configured to store instructions;
• and
• one or more processors communicatively coupled to the memory, the one or more processors configured to execute the instructions to:
• detect a need to tune away at least one of multiple radio resources utilized by the apparatus to communicate with multiple serving cells of the first RAT;
• determine, for each serving cell of the multiple serving cells, a tune-away metric based on one or more performance impact factors associated with the serving cell being tuned away;
• select at least one serving cell of the multiple serving cells to be tuned away based on the determined tune-away metrics of each of the multiple serving cells;
• and
• tune one or more radio resources corresponding to the selected at least one serving cell away from the first RAT to the second RAT.

• means for determining, for each of the multiple serving cells, a tune-away metric based on one or more performance impact factors associated with the serving cell being tuned away;
• means for selecting at least one serving cell of the multiple serving cells to be tuned away based on the determined tune-away metrics of each of the multiple serving cells;
• and
• means for tuning one or more radio resources corresponding to the selected at least one serving cell away from the first RAT to the second RAT.

A non-transitory computer-readable medium storing computer executable code for performing a tune-away from a first radio access technology (RAT) to a second RAT, comprising:

• code for causing a computer to:
• detect a need to tune away at least one of multiple radio resources utilized by a user equipment to communicate with multiple serving cells of the first RAT;
• determine, for each of the multiple serving cells, a tune-away metric based on one or more performance impact factors associated with the serving cell being tuned away;
• select at least one serving cell of the multiple serving cells to be tuned away based on the determined tune-away metrics of each of the multiple serving cells;
• and
• tune one or more radio resources corresponding to the selected at least one serving cell away from the first RAT to the second RAT.
