1. An electronic device comprising:
memory storing instructions;
communication circuitry configured to support ultra-wide band (UWB) technology; and
at least one processor operatively coupled to the communication circuitry,
wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
receive downlink frames to be used for localization of the electronic device in a downlink time period from anchor nodes through the communication circuitry,
based on determining a failure to calculate a location of the electronic device using time difference of arrival (TDoA) information measured for the downlink frames, determine to perform uplink TDoA-based localization of the electronic device,
based on determining to perform the uplink TDoA-based localization, broadcast an uplink frame including anchor information identifying at least one anchor node among the anchor nodes related to the received downlink frames and device information about the electronic device in an uplink time period through the communication circuitry, and
receive location information indicating a location of the electronic device calculated based on the uplink frame through the communication circuity.
