Configuration method of communication path for portable communication device and portable communication device supporting the same

A method for processing a communication path in a portable communication device, the method comprising:

• identifying whether at least some of a plurality of active elements included in a communication circuit disposed between an antenna and a communication processor are in an abnormal state;
• and
• based on an abnormal state of a first active element for supporting delivery of a signal of a first frequency band among the at least some of the plurality of active elements being detected, controlling the portable communication device to change a communication path associated with the first active element to a communication path associated with a second active element different from the first active element among the plurality of active elements to deliver the signal of the first frequency band,
• wherein the method further comprises controlling the communication circuit to transmit capability information to a base station, and
• wherein the capability information includes a notification about a status of processing the signal of the first frequency band based on the second active element.

A portable communication device, comprising:

• a communication processor;
• at least one antenna;
• and
• a communication circuit disposed between the communication processor and the at least one antenna and configured to support a plurality of radio frequency transmit paths and a plurality of radio frequency receive paths to respectively or selectively support a plurality of radio frequency bands,
• wherein the communication processor is configured to:
• determine whether a first transmit path is abnormal based on signal quality of the first transmit path for transmitting a first radio frequency signal among the plurality of radio frequency transmit paths and control the portable communication device to change a path to output the first radio frequency signal through a second transmit path different from the first transmit path, based on an abnormality occurring in the first transmit path, and
• wherein the communication processor is configured to control the portable communication device to change a multi-input multi-output (MIMO) order, based on a first receive path including MIMO Rx, and change one of MIMO Rx paths to a diversity receiver (DRx) path included in the communication circuit.
