Abstract
A system that incorporates teachings of the present disclosure may include, for example, a non-transitory computer-readable storage medium, which can include computer instructions to determine a subset of use cases from a group of use cases stored in a memory of a communication device, and to determine a target use case from among the subset of use cases based on an operational parameter associated with a transceiver of the communication device. Additional embodiments are disclosed.
Claims10
A method comprising:
- identifying, by a system of a communication device, a subset of use cases from a group of use cases based on a usage condition determined for the communication device, each of the use cases corresponding to a tuning state for tunable elements of an impedance matching circuit of the communication device;
- applying, by the system, each tuning state of the subset of use cases to the tunable elements and measuring, by the system, a signal parameter for a received signal at each tuning state to generate a group of signal parameters;
- 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.
A communication device comprising:
- a transceiver;
- an impedance matching circuit coupled with the transceiver;
- a memory that stores computer instructions;
- and
- a processor coupled with the memory and the impedance matching circuit, wherein the processor, responsive to executing the computer instructions, performs operations comprising:
- identifying a subset of use cases from a group of use cases based on a usage condition determined for the communication device, each of the use cases corresponding to a tuning state for tunable elements of the impedance matching circuit;
- applying each tuning state of the subset of use cases to the tunable elements and measuring a signal parameter for a received signal at each tuning state to generate a group of signal parameters;
- selecting 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.
A non-transitory computer-readable storage device comprising computer instructions which, responsive to being executed by a processor of a communication device, cause the processor to perform operations comprising:
- selecting a subset of use cases from a group of use cases based on a usage condition of the communication device;
- collecting parametric measurements associated with a transceiver of the communication device for each tuning state corresponding to each of the subset of use cases during the operation of the communication device, wherein the collecting of the parametric measurements comprises collecting multiple parametric measurements for each tuning state corresponding to each of the subset of use cases during the operation of the communication device;
- selecting a target use case from among the subset of use cases based on the parametric measurements;
- and
- tuning an impedance matching circuit of the communication device by adjusting a variable reactance component based on the target use case.
