Abstract

The present invention relates to a method and apparatus of calculating a location of an electronic device. The present invention comprises receiving a common packet from a host device, the common packet containing at least any one of frequency-related information or information on a time when a data packet is transmitted; receiving the data packet based on the information contained in the common packet, the data packet containing at least any one of location-related information or antenna-related information of the host device; obtaining angle information indicating a location relation with the host device using at least any one of the location-related information or the antenna-related information of the received data packet; and calculating the location of the electronic device based on the angle information.

First claim

1 . A method for calculating a location of an electronic device, the method comprising:
receiving a common packet from a host device, wherein the common packet includes at least one of a time information or frequency related information through which a data packet is transmitted; receiving the data packet based on information included in the common packet from the host device, wherein the data packet includes at least one of a location related information, or antenna related information of the host device; obtaining angle information indicating a location relation with the host device using at least one of the location related information or the antenna related information included in the received data packet; and calculating the location of the electronic device based on the angle information.

2 . The method of claim 1 ,
wherein the data packet is transmitted through multiple antennas of the host device.

3 . The method of claim 1 ,
wherein the location related information includes at least one of longitude, latitude or an altitude of the host device.

4 . The method of claim 1 ,
wherein the common packet and the data packet are transmitted through different channels from each other.

5 . The method of claim 1 , further comprising:
measuring a received signal strength of the data packet, wherein the received data packet includes a transmitted signal strength of the data packet, and wherein the location of the electronic device is calculated based on at least one of the angle information, the received signal strength or the transmitted signal strength.

6 . An electronic device for calculating a location of the electronic device, the electronic device comprising:
a communication unit configured to receive a common packet from a host device and receive a data packet based on information included in the common packet, wherein the common packet includes at least one of a time information or frequency related information trough which a data packet is transmitted, and wherein the data packet includes at least one of location related information, or antenna related information of the host device; and a controller configured to obtain angle information indicating a location relation with the host device using at least one of the location related information or the antenna related information included in the received data packet, and calculate the location of the device based on the angle information.

7 . The electronic device of claim 6 ,
wherein the data packet is transmitted through multiple antennas of the host device.

8 . The electronic device of claim 6 ,
wherein the location related information includes at least one of longitude, latitude or an altitude of the host device.

9 . The electronic device of claim 6 ,
wherein the common packet and the data packet are transmitted through different channels from each other.

10 . The electronic device of claim 6 , further comprising:
a signal measurement configured to measure a received signal strength of the received data packet, wherein the received data packet includes a transmitted signal strength of the data packet, and wherein the controller calculates the location of the electronic device based on at least one of the angle information, the received signal strength or the transmitted signal strength.

11 . A method for calculating a location of an electronic device, the method comprising:
receiving a common packet from a host device, wherein the common packet includes at least one of location related information or antenna related information of the host device; obtaining angle information indicating a location relation with the host device using at least one of the location related information or the antenna related information included in the received data packet; and calculating the location of the electronic device based on the obtained angle information.

12 . An electronic device for calculating a location of the electronic device, the electronic device comprising:
a communication unit configured to receive a common packet from a host device, wherein the common packet includes at least one of location related information or antenna related information of the host device; and a controller configured to obtain angle information indicating a location relation with the host device using at least one of the location related information or antenna related information included in the received data packet, and calculate the location of the electronic device based on the obtained angle information.
