1. A method comprising:
- accessing, by a system of a communication device, a memory that includes information representative of a group of use cases that are indexed in the memory according to usage conditions of the communication device, each of the group of use cases corresponding to a tuning state for tunable elements of an impedance matching circuit of the communication device;
selecting, by the system, a subset of use cases from the group of use cases based on a usage condition determined for the communication device;
applying, by the system, each tuning state of the subset of use cases to the tunable elements without applying non-selected use case of the group of use cases and measuring, by the system, a signal parameter for a signal at each tuning state to generate a group of signal parameters, wherein the signal parameter is associated with signal quality; and
selecting, by the system, a target use case from among the subset of use cases based on a desired signal parameter selected from among the group of signal parameters.
