The electronic device 142 may be installed in the space 162 (eg, a space such as a room). The electronic device 144 may be installed in the space 164 (eg, a space such as a room). However, the installation space of the electronic devices 120, 142, and 144 is not limited to indoor space, and the spaces 160, 162, and 164 shown in FIG. 1 are merely examples for explanation.

Figure 2 is a diagram for explaining changes in channel state information according to an embodiment.

Referring to FIG. 2, according to one embodiment, channel state information refers to the result of overlapping the amplitude and/or phase of wireless signals propagating through a plurality of paths (L1, L2, and L3). can do.

According to one embodiment, a wireless signal may propagate from the electronic device 120 to the electronic device 142 through a plurality of paths L1, L2, and L3. The wireless signal propagating through the path L3 may be reflected by the object 210. The wireless signal propagating through the path L2 may be reflected by the object 220. Each of the wireless signals propagating through the plurality of paths (L1, L2, L3) may have different phases and/or different amplitudes. The electronic device 142 may overlap wireless signals received through a plurality of paths (L1, L2, and L3) and obtain channel state information (CSI).

According to one embodiment, when the propagation environment of a wireless signal changes, channel state information may change. For example, a case where a user enters a space where a wireless signal propagates (e.g., spaces 160, 162, and 164 in FIG. 1) may be considered. Among the wireless signals propagating through the paths L1, L2, and L3, at least some wireless signals may be subject to interference by the user. Due to user interference, the phase and/or amplitude of the wireless signal may vary, and channel state information between the electronic device 120 and the electronic device 142 may change.

According to one embodiment, the electronic devices 120 and 142 may detect an event based on channel state information. For example, the electronic devices 120 and 142 may detect events such as detecting a user entering the space 160, 162, and 164 or detecting an intruder.

According to one embodiment, the sensing sensitivity of the electronic devices 120 and 142 may vary depending on the location of the event. The sensing sensitivity of the electronic devices 120 and 142 depending on the location of the event will be described in detail with reference to FIG. 3.

FIG. 3 is a diagram for explaining the sensing sensitivity of an electronic device according to an embodiment.

Referring to FIG. 3 , according to one embodiment, surrounding electronic devices (e.g., electronic device 120 of FIGS. 1 and 2) and electronic devices (e.g., electronic device 142 of FIGS. 1 and 2, Sensing sensitivity may be high in the vicinity of the electronic device 144 of FIG. 1 and may decrease as the distance from the electronic device 120 and/or the electronic devices 142 and 144 increases.

An event that occurs inside the sensing coverage 410 may change the channel state information between the electronic device 120 and the electronic device 142 and the channel state information between the electronic device 120 and the electronic device 144.

According to one embodiment, the electronic device 142 may detect the occurrence of an event (eg, user entry) based on a change in channel state information between the electronic device 120 and the electronic device 142. For example, the electronic device 120 may calculate a value corresponding to a change in channel state information and detect the occurrence of an event based on a comparison result between the calculated value and a threshold value. That is, the value corresponding to the change in channel state information may indicate the probability of occurrence of the event.

According to one embodiment, the electronic device 142 sends the electronic device 144 and the electronic device 120 to the electronic device 144 in response to a change in channel state information (e.g., detection of an event occurrence) with the electronic device 120. ) can transmit a query about channel status information. As described above, an event occurring inside the sensing coverage 410 may change the channel state information between the electronic device 120 and the electronic device 144. The electronic device 144 may calculate a value corresponding to a change in channel state information and detect the occurrence of an event based on a comparison result between the calculated value and the threshold value. The electronic device 144 may transmit a response regarding whether an event has occurred to the electronic device 142. Since events occurring inside the sensing coverage 410 (e.g., the surrounding space 160 of the electronic device 120) may have a similar level of impact on both the electronic device 142 and the electronic device 144, (144) It is also possible to detect the occurrence of an event.

In this case, the user may be located outside the sensing coverage 530 formed around the electronic device 144 and the sensing coverage formed around the electronic device 120 (e.g., the sensing coverage 410 in FIG. 4). . An event that occurs inside the sensing coverage 510 may change channel state information between the electronic device 142 and the electronic device 120.

A query for channel status information between channels can be transmitted. An event that occurs inside the sensing coverage 510 may not significantly change the channel state information between the electronic device 120 and the electronic device 144. The electronic device 144 may transmit a response indicating that the occurrence of an event has not been detected to the electronic device 142.

According to one embodiment, the electronic device 142 may receive a response from the electronic device 144 and estimate the location of the event based on the response. Specifically, when receiving a response from the electronic device 144 that the occurrence of an event was not detected, the electronic device 142 may estimate that the event occurred in the surrounding space 162 of the electronic device 142.

According to one embodiment, the electronic device 144 may detect the occurrence of an event and transmit a query about channel state information between the electronic device 142 and the electronic device 120 to the electronic device 142. The electronic device 144 may estimate the location of the event based on the response received from the electronic device 142. The operating method of the electronic device 144 may be substantially the same as the operating method of the electronic device 142. Therefore, redundant explanations will be omitted.

According to one embodiment, when a plurality of electronic devices (e.g., a plurality of transmitters) exist in a wireless network (e.g., the wireless network 100 of FIG. 1), the plurality of electronic devices (e.g., a plurality of receivers) s) may transmit a query between electronic devices (e.g., receivers such as electronic devices 142 and 144) connected to the same electronic device (e.g., a transmitter such as the electronic device 120).

The server 1308 can analyze channel state information, detect the occurrence of an event, and estimate the location of the event. The method of detecting the occurrence of an event of the server 1308 and the method of estimating the location of the event may be substantially the same as the method of operating the electronic devices 142 and 144 described above. Therefore, redundant explanations will be omitted.

The electronic devices 142 and 144 may determine the location of the event based on event detection by each of the electronic devices 142 and 144. For example, when the electronic device 142 and the electronic device 144 detect the occurrence of an event, the electronic devices 142 and 144 are connected to the space 160 (e.g., the sensing coverage 410 of FIG. 4). It can be assumed that an event occurred in space. For example, when the electronic device 142 detects the occurrence of an event and the electronic device 144 does not detect the occurrence of the event, the electronic device 142 detects the occurrence of the event in the space 162 (e.g., the sensing coverage 510 of FIG. 5). It can be assumed that the event occurred in a space associated with . For example, when the electronic device 144 detects the occurrence of an event and the electronic device 142 does not detect the occurrence of the event, the electronic device 144 detects the occurrence of the event in the space 164 (e.g., sensing coverage 530 in FIG. 5). It can be assumed that the event occurred in a space associated with . According to one embodiment, the electronic devices 142 and 144 can estimate the location of an event that occurred in space within a wireless network by transmitting a query for channel state information to each other.

According to one embodiment, in order to estimate the location of an event, adjustment of the locations of the electronic devices 120, 142, and 144 and/or the sensing coverages 410, 510, and 530 may be necessary. . For example, the sensing coverages 410, 510, and 530 may be adjusted by changing a value (e.g., a threshold related to sensing sensitivity) stored in a memory (e.g., memory 1330 of FIG. 13). For example, the electronic devices 142 and 144 may provide a guide to the user regarding the locations of the electronic devices 142 and 144.

For example, the electronic device 742 detects a change in channel state information between the electronic device 722 and the electronic device 742 and detects a change in the channel state information between the electronic device 724 and the electronic device 742. If not detected, the electronic device 742 may estimate that the event occurred in the surrounding space 710 of the electronic device 722. For example, the electronic device 742 detects a change in channel state information between the electronic device 724 and the electronic device 742 and detects a change in the channel state information between the electronic device 722 and the electronic device 742. If not detected, the electronic device 742 may estimate that the event occurred in the surrounding space 720 of the electronic device 724.

In this case, the electronic device 742 may estimate that the event occurred in the surrounding space 730 of the electronic device 742. According to one embodiment, the event detection method and the event occurrence location estimation method of the electronic device 742 are substantially similar to the methods of electronic devices (e.g., the electronic devices 142 and 144 of FIGS. 1 and 4 to 6). can be the same. Since the electronic device 742 has channel state information with the electronic devices 722 and 724, the operation of transmitting a query can be omitted.

FIG. 8 is a flowchart illustrating a method for detecting the occurrence of an event in an electronic device according to an embodiment.

Referring to FIG. 8, according to one embodiment, operations 810 to 850 may be performed sequentially, but are not limited thereto. For example, two or more operations may be performed in parallel.

The operating method of the electronic device 142 and the operating method of the electronic device 144 may be substantially the same. Hereinafter, for convenience of explanation, the electronic device 142 will be used as an example.

In operation 810, the electronic device 142 selects a space (e.g., the space of FIGS. 1, 4-6) within the coverage of the electronic device (e.g., the electronic device 120 of FIGS. 1, 2, and 4-6). Events (e.g., occupancy detection and/or intruder detection) that occur in fields 160 to 164 may be detected. For example, the electronic device 142 may detect the occurrence of an event based on channel state information with the electronic device 120.

In operation 830, the electronic device 142 may transmit a query to the electronic device 144 connected to the electronic device 120. The query may be about channel state information between the electronic device 120 and the electronic device 144. The electronic device 144 may detect the occurrence of an event based on channel state information with the electronic device 120. The event detection method of the electronic device 144 may be substantially the same as the event detection method of the electronic device 142.

In operation 850, the electronic device 142 may estimate the location of the event based on the response received from the electronic device 144. For example, when receiving a response from the electronic device 144 that the occurrence of an event has been detected, the electronic device 142 may estimate that the event occurred in the surrounding space 160 of the electronic device 120. For example, when receiving a response from the electronic device 144 that the occurrence of an event was not detected, the electronic device 142 may estimate that the event occurred in the surrounding space 162 of the electronic device 142.

According to one embodiment, the electronic devices 142 and 144 can estimate the location of an event that occurred in space within a wireless network by transmitting a query for channel state information to each other.

FIG. 9 is a diagram illustrating a method of performing an action according to event detection of an electronic device, according to an embodiment.

Referring to FIG. 9, according to one embodiment, operations 910 to 950 may be performed sequentially, but are not limited thereto. For example, two or more operations may be performed in parallel. Electronic devices (e.g., electronic devices 142 and 144 of FIGS. 1 and 4 to 6) may perform actions based on the location of an event. The operating method of the electronic device 142 and the operating method of the electronic device 144 may be substantially the same. Hereinafter, for convenience of explanation, the electronic device 142 will be used as an example.

In operation 910, the electronic device 142 may estimate the location of the event.

In operation 930, the electronic device 142 may check whether an event occurred in a space associated with the electronic device 142 (eg, space 162 in FIGS. 1 and 4 to 6).

In operation 950, when an event occurs in the space 162, the electronic device 142 may perform an action. For example, when the electronic device 142 detects that a user has entered the space 162, it may operate a light (eg, Iot bulb) and/or an air conditioner installed inside the space 162. However, even when an event is estimated to have occurred in a space (e.g., the space 160 in FIGS. 1, 4, and 6), the electronic device 142 may detect devices installed inside the space 160 (e.g., the space 160 in FIGS. 1, 4, and 6). You can also perform actions to control IoT devices. Actions can be pre-mapped by the user depending on where the event occurs.

Electronic devices (e.g., electronic devices 142 and 144 of FIGS. 1 and 4 to 6) may provide a user with a guide for setting the positions of the electronic devices 142 and 144. The user may adjust the positions of the electronic devices 142 and 144 based on the guides of the electronic devices 142 and 144. Operations 1010 to 1050 may generally be performed during the installation process (or learning process) of the electronic devices 142 and 144, but are not limited thereto. For example, even when the electronic devices 142 and 144 cannot estimate the location of an event due to a change in the radio wave environment, operations 1010 to 1050 may be performed. For example, a change in the propagation environment may include the location of a new obstacle in the propagation path and/or the disappearance of an existing obstacle. The operating method of the electronic device 142 and the operating method of the electronic device 144 may be substantially the same. Hereinafter, for convenience of explanation, the electronic device 142 will be used as an example.

In operation 1010, the electronic device 142 may detect the occurrence of an event and estimate the location of the event. In operation 1010, the event may mean that the user enters the space where the electronic device 142 is located (eg, space 162 in FIGS. 1 and 4 to 6).

In operation 1030, the electronic device 142 may check whether the sensing coverage formed around the electronic device 144 (e.g., the sensing coverage 530 of FIG. 5) and the space 162 overlap.

The electronic device 142 may check whether the sensing coverage 530 and the space 162 overlap based on the response from the electronic device 144. For example, when the electronic device 144 receives a response indicating that an event has occurred, the electronic device 142 may determine that the sensing coverage 530 and the space 162 overlap.

In operation 1050, when the sensing coverage 530 and the space 162 overlap, the electronic device 142 may advise the user to change the location of the electronic device 142. After the position of the electronic device 142 is adjusted by the user, the electronic device 142 may perform operations 1010 to 1050 again.

An event can be detected based on changes in channel state information, and the location of the event can be estimated. For normal operation of the electronic devices 142 and 144, an appropriate detection period may need to be set. Hereinafter, for convenience of explanation, the event 710 occurs at time ta in space (e.g., space 162 in FIGS. 1 and 4 to 6), and the event 710 occurs at time ta in space (e.g., space 162 in FIGS. 1 and 4 to 6). 4, and it is assumed that the event 730 occurs at time tb within the space 164 of FIG. 6.
