These devices can provide various services, such as data transfer services, multimedia playback services, document printing services, display services, wireless docking services, or wireless serial bus (WSB) services.

[0004] A plurality of electronic devices can form a wireless communication group (e.g., a Wi-Fi Direct communication group) for using a Wi-Fi Direct service, and one of the plurality of electronic devices forming the group can act as a group owner (GO) and the rest can act as group clients (GC).

[0005] An electronic device that is a group owner of a wireless communication group can function like an access point in a wireless LAN network. An electronic device that is a group client of a wireless communication group can function like a station in a wireless LAN network.

[0006] Group creation using Wi-Fi Direct technology allows for not only 1:1 connections but also 1:N connections, and the number of acceptable group clients may vary depending on the performance of the electronic device that owns the group.

[0030]

[0031] FIG. 1 is a diagram illustrating a network structure of a Wi-Fi Direct communication group according to one embodiment.

[0032] Referring to FIG. 1, according to one embodiment, a Wi-Fi Direct communication group may be configured to include a plurality of electronic devices (e.g., 101, 102, 201, and / or 202). The plurality of electronic devices (101, 102, 201, and / or 202) may form a Wi-Fi Direct communication group according to a Wi-Fi Direct related protocol defined in an IEEE 802.11 Alliance technology standard (e.g., IEEE 802.11g and / or IEEE 802.11n).

[0033] According to one embodiment, any one of the plurality of electronic devices (101, 102, 201, and / or 202) may act as a group owner (e.g., electronic device (102)). The electronic device (102), which is the group owner, may establish a connection with the electronic devices (101, 201, and / or 202), which are group clients, to form a direct group.

[0034] According to one embodiment, an electronic device (102) that is a group owner may perform operations similar to an access point (AP) that constitutes a WLAN network. The group owner may be determined during the process of forming a Wi-Fi Direct communication group. The group owner may be determined through a group owner negotiation protocol during a one-to-one connection process between electronic devices.

[0035] According to one embodiment, an electronic device (102) that is a group owner can control connections between client electronic devices (101, 201 and / or 202). The electronic device (102) that is a group owner can connect with each client electronic device (101, 201 and / or 202) in a 1:1 or 1:N manner.

[0036] According to one embodiment, each of the electronic devices (101, 201, and / or 202) may be the same type of electronic device as the electronic device (102) or a different type of electronic device. For example, the electronic devices (101, 102, 201, and / or 202) may be general electronic devices such as a smart phone, a portable terminal, a mobile terminal, a personal digital assistant (PDA), a portable multimedia player (PMP) terminal, a laptop computer, or a personal computer, which are terminals that operate in a Wi-Fi P2P network. The electronic devices (101, 102, 201, and / or 202) may be various electronic devices such as a Bluetooth speaker, television, printer, or camera that support Wi-Fi Direct and provide data communication-based services.

[0037]

[0038] FIG. 2 is a flowchart illustrating a Wi-Fi Direct communication group creation operation according to one embodiment.

[0039] Referring to FIG. 2, according to one embodiment, an electronic device (101) and an electronic device (102) can create a Wi-Fi Direct communication group. The operations of each of the electronic device (101) and the electronic device (102) described through FIG. 2 can be triggered by an application utilizing Wi-Fi Direct. The operations of each of the electronic device (101) and the electronic device (102) described through FIG. 2 can also be triggered by a user input to a WSC (Wi-Fi simple configuration) button.

[0040] According to one embodiment, in operation 210, each of the electronic device (101) and the electronic device (102) may perform Wi-Fi direct device discovery. The electronic device (101) and the electronic device (102) may perform Wi-Fi direct device discovery upon entering a Wi-Fi direct device discovery mode.

[0041] According to one embodiment, each of the electronic device (101) and the electronic device (102) may perform Wi-Fi Direct device discovery by repeatedly performing a search to discover other electronic devices and a listen to wait for a response received from the other electronic devices.

[0042] According to one embodiment, the electronic device (101) and the electronic device (102) can perform a channel scan in a search state. The scan can be repeatedly performed a specified number of times or less for all communicable channels of the electronic device (101) and the electronic device (102) (e.g., channels 1 to 11) or for social channels for quick discovery (e.g., channels 1, 6, and 11). The listen of the electronic device (101) operating as a group client can be limited to one of the social channels, and the selected channel can be fixed during the discovery process. The scan can be performed in a scan manner according to the 802.11 standard protocol.

[0043] According to one embodiment, the electronic device (101) and the electronic device (102) can maintain a standby state by selecting one of the full channel or the social channel in the standby state.

[0044] According to one embodiment, the electronic device (101) and the electronic device (102) can perform Wi-Fi Direct device discovery by exchanging a probe request and a probe response. The electronic device (101) can transmit a probe request to the electronic device (102), and the electronic device (102) can transmit a probe response to the electronic device (101). The probe request can include a peer-to-peer information element (P2P IE). The probe response can include a P2P IE. The P2P IE can include a P2P attribute. The P2P attribute can be configured as shown in Table 4, which will be described later.

[0045] According to one embodiment, the entities / states that can transmit probe responses are as follows. First, as with the existing 802.11 MAC (media access control), the group owner who has already created a Wi-Fi Direct communication group can transmit the probe response. As described above, the group owner performs the same role as the existing AP, so it must naturally respond to the probe request. The group owner can include the P2P IE in the probe response. The group owner can also reply with a probe response to the probe request of an existing legacy Wi-Fi device that does not support the P2P IE. The group owner can be compatible with existing legacy Wi-Fi devices that do not support the P2P IE.

[0046] In one embodiment, a second Wi-Fi Direct device that is not a group owner can respond to a probe request while in a listening state. In the listening state, the Wi-Fi Direct device can maintain a receiving mode and send a probe response in response to a received probe request. The Wi-Fi Direct device can only respond to probe requests that include a P2P IE. The Wi-Fi Direct device may not respond to probe requests from legacy Wi-Fi devices that do not support the P2P IE.

[0047] In one embodiment, the third Wi-Fi Direct device may respond to a probe request while already connected to the AP in 802.11 Station mode. The Wi-Fi Direct device may support concurrent mode. In concurrent mode, the Wi-Fi Direct device may form a Wi-Fi Direct communication group and maintain a connection to the AP.

[0048] According to one embodiment, the electronic device (101) and the electronic device (102) can find each other by reaching a common channel through repeated searching and waiting. The electronic device (101) and the electronic device (102) can identify each other through probe requests or probe responses.

[0049] According to one embodiment, if a Wi-Fi Direct communication group has already been formed prior to the Wi-Fi Direct discovery of the electronic device (101) and the electronic device (102), either the electronic device (101) or the electronic device (102) may be a group owner. For example, if the electronic device (102) is a group owner, the electronic device (101) may discover the electronic device (102) as the group owner through the Wi-Fi Direct device discovery. In this case, the electronic device (102) may receive a probe request from the electronic device (101) while maintaining a standby state without performing a search.

[0050] According to one embodiment, in operation 220, the electronic device (101) and the electronic device (102) may perform service discovery. The electronic device (101) and the electronic device (102) may perform service discovery to exchange information about services provided by upper layers to identify mutually compatible services.

[0051] According to one embodiment, service discovery may be performed through the exchange of a service discovery query and a service discovery response. The electronic device (101) may transmit a service discovery query to the electronic device (102), and the electronic device (102) may transmit a service discovery response to the electronic device (101).

[0052] According to one embodiment, the electronic device (101) may specify a service protocol type through a service discovery query and transmit service information matching the service protocol type as query data. The electronic device (102) may transmit the service protocol type and response data through a service discovery response. Service discovery may be performed to identify services between network-connected electronic devices when the electronic devices (101) and (102) are connected above the MAC layer (e.g., layer 2), i.e., at layer 3. However, service discovery may also be performed flexibly at any stage according to an arbitrary designation of an upper layer regardless of the MAC protocol. Service discovery may be performed to identify the service protocol and / or service type that the other party can support. Accordingly, it is possible to prevent the occurrence of a problem in which data sharing (e.g., file sharing) is impossible due to mismatched service protocol types after the electronic devices (101) and (102) are connected.

[0053] According to one embodiment, in operation 230, the electronic device (101) and the electronic device (102) may perform provision discovery.

[0054] According to one embodiment, an electronic device (101) and an electronic device (102) can perform provision discovery by exchanging a provision discovery request and a provision discovery response. The electronic device (101) can transmit a provision discovery request to the electronic device (102), and the electronic device (102) can transmit a provision discovery response to the electronic device (101).

[0055] In one embodiment, the provisioning search request may include a WSC configuration method. For example, the WSC configuration method may be one of PBC, PIN from Display, or PIN from Keypad. For example, the WSC configuration method may be determined by the electronic device (102).

[0056] According to one embodiment, the electronic device (102) that has received the provisioning search request may notify the user by displaying on a display (not shown) that the provisioning search request has been received. For example, if the provisioning search request includes a WSC setting method, the electronic device (102) may display information about the WSC setting method on the display (not shown). The electronic device (102) may display a PIN or a window for entering a PIN according to the WSC setting method, thereby displaying information about the WSC setting method. For example, the electronic device (102) may display a pop-up window to notify the user of the name of the electronic device (101) that transmitted the provisioning search request and / or the WSC setting method, thereby allowing the user to decide whether to accept the connection and whether to set up the WSC.

[0057] According to one embodiment, in operation 240, the electronic device (101) and the electronic device (102) may perform group owner negotiation. The electronic device (101) may determine a group owner of a Wi-Fi Direct communication group to be formed with the electronic device (102).

[0058] In one embodiment, the electronic device (101) may determine a group owner (e.g., the electronic device (102)) by exchanging a group owner negotiation request, a group owner negotiation response, and / or a group owner negotiation confirm with the electronic device (102).

[0059] According to one embodiment, the electronic device (101) and the electronic device (102) can determine the group owner by comparing the group owner intents designated for each device. The group owner intent of each device can be obtained from the group owner intent properties (e.g., see Table 4). The electronic device (101) and the electronic device (102) can determine the group owner electronic device based on information such as the properties of the Wi-Fi Direct communication group to be formed, the operating channel, and the listen timing. If the Wi-Fi Direct communication group has already been formed, either the electronic device (101) or the electronic device (102) may already be the group owner, and thus group owner negotiation may be omitted.

[0060] According to one embodiment, a group owner negotiation request, a group owner negotiation response, and / or a group owner negotiation confirmation may include a channel list attribute (e.g., see Table 4). The electronic device (101) and the electronic device (102) may transmit information about available channels and information about available bandwidth to each other through the channel list attribute. The channel list attribute may be included in a peer-to-peer information element (P2P IE). The P2P IE may include a P2P attribute. The channel list attribute may be any one of the P2P attributes (e.g., see Table 4). The channel list attribute may be composed of fields as shown in Table 1.

[0061]

[0062]

[0063]

[0064] The channel list attribute may include a channel entry list field. Information about available channels and available bandwidth may be included (e.g., embedded) in the channel entry list field. The channel entry list field may be composed of fields as shown in Table 2.

[0065]

[0066]

[0067]

[0068] The channel entry list field may include an operating class field that contains information about the bandwidth available to the device. The channel entry list field may include a number of channels field that indicates the number of channels available to the device. The channel entry list field may include a channel list field that contains information about the channels available to the device.

[0069] In one embodiment, when group owner negotiation is terminated, the electronic device (102) may act as a WSC registrar as a group owner, and the electronic device (101) as a group client may act as a WSC enrollee. The electronic device (101) and the electronic device (102) may perform provisioning to exchange credentials.

[0070] According to one embodiment, in operation 250, the electronic device (101) may perform provisioning with the electronic device (102).

[0071] According to one embodiment, the probe request, probe response, association request, and / or association response exchanged during provisioning may include high throughput (HT) operation information, very high throughput (VHT) operation information, and / or high efficiency (HE) operation information. Each electronic device may transmit information about available bandwidth to an external electronic device through the HT operation information, the VHT operation information, and / or the HE operation information. For example, the VHT operation information may be composed of fields as shown in Table 3.

[0072]

[0073]

[0074] VHT operation information may include a channel width field that contains information about the bandwidth available to the device.

[0075] According to one embodiment, an electronic device (101) and an electronic device (102) can form a Wi-Fi Direct communication group by performing provisioning. An electronic device (102), which is a group owner, can register the electronic device (101) as a group client. The electronic device (102) can control the Wi-Fi Direct communication group connection of a group client (e.g., the electronic device (101)) through an operation channel. The electronic device (101), which is a group client, can connect to the electronic device (102), which is a group owner, through credentials verified through provisioning. The electronic device (101) and the electronic device (102) can perform data transmission and reception based on the Wi-Fi Direct connection.

[0076]

[0077] Figure 3 is a diagram for explaining channel allocation in the 5 GHz band.

[0078] Referring to FIG. 3, according to one embodiment, channels of a 5 GHz band can be identified. The 5 GHz band can be divided into a UNII-1 band, a UNII-2a, a UNII-2c, and a UNII-3 band. The UNII-1 band can include channel 36 (e.g., center frequency 5180 MHz) to channel 48 (e.g., center frequency 5240 MHz). The UNII-2a band can include channel 54 (e.g., center frequency 5260 MHz) to channel 64 (e.g., center frequency 5320 MHz). The UNII-2c band can include channel 100 (e.g., center frequency 5500 MHz) to channel 144 (e.g., center frequency 5720 MHz). The UNII-3 band may include channel 149 (e.g., center frequency 5745 MHz) to channel 165 (e.g., center frequency 5825 MHz).

[0079] In one embodiment, the UNII-2a and UNII-2c bands in the 5 GHz band may be designated as dynamic frequency selection (DFS) channels. DFS channels may be utilized for military radar, satellite communications, and / or weather radar. The use of DFS channels may be subject to restrictions.

[0080] In one embodiment, a DFS owner can utilize a DFS channel. The DFS owner may be a device permitted to occupy the DFS channel. The DFS owner may scan for radar signals. If no active radar signals are detected on the DFS channel, the DFS owner may utilize (e.g., occupy) the DFS channel. The DFS owner may be an access point (AP).

[0081] In one embodiment, not only the DFS owner, but also devices associated with the AP that is the DFS owner may utilize the DFS channel. For example, a device associated with or receiving a beacon from an AP that is the DFS owner may utilize the DFS channel. Two devices associated with an AP that is the DFS owner may utilize the DFS channel for direct communication with each other.

[0082] According to one embodiment, two devices associated with an AP, which is a DFS owner, can exchange information about the AP for DFS channel-based communication. The AP information may be included in a peer-to-peer attribute exchanged between the two devices. The P2P attribute may be included in a peer-to-peer information element (P2P IE). The P2P attribute may be configured as shown in Table 4.

[0083]

[0084]

[0085]

[0086] A P2P attribute may include a group owner intent attribute (e.g., corresponding to attribute ID 4). A P2P attribute may include a channel list attribute (e.g., corresponding to attribute ID 11). A P2P attribute may include a WLAN AP information attribute (e.g., corresponding to attribute ID 30). Information about the AP that is the DFS owner may be included (e.g., embedded) in the WLAN AP information attribute. The WLAN AP information attribute may be composed of fields as shown in Table 5.

[0087]

[0088]

[0089]

[0090] The WLAN AP information attribute may include an AP info list field. Information about the AP that is the DFS owner may be included (e.g., embedded) in the AP info list field. The AP info list field may consist of fields as shown in Table 6.

[0091]

[0092]

[0093]

[0094] The AP info list field may include a flag field indicating whether the device is connected to an AP. The AP info list field may include a BSSID field for identifying the AP. The AP info list field may include an operation class field indicating the frequency band (e.g., channel) on which the AP operates. The AP info list field may include a channel number field indicating the number of channels on which the AP operates.

[0095]

[0096] FIG. 4 is a diagram for explaining a Wi-Fi direct connection between electronic devices, FIG. 5 is a diagram for explaining a bandwidth available in the 5 GHz band for Wi-Fi direct communication between electronic devices, and FIG. 6 is a diagram for explaining a channel and bandwidth utilized in Wi-Fi direct communication between electronic devices.

[0097] Referring to FIG. 4, each of the electronic devices (401) and (402) may be devices that support both the Wi-Fi 5GHz band. Each of the electronic devices (401) and (402) may be devices that support a bandwidth of 160MHz. Various APs (e.g., 411 to 414) may exist around the electronic devices (401) and (402) (e.g., within a coverage area where APs can be identified). The electronic devices (401) and (402) may perform Wi-Fi direct (Wi-Fi direct) communication with each other independently of the surrounding APs (411 to 414). The electronic devices (401) and (402) may be connected to each other via Wi-Fi direct with a bandwidth of 80MHz of the 5GHz band (e.g., channel 149).

[0098] Referring to FIG. 5, the electronic device (401) and the electronic device (402) can check the frequency band (e.g., channel) and bandwidth that can be utilized for Wi-Fi Direct communication. The electronic device (401) and the electronic device (402) can only select a channel and bandwidth within the UNII-1 band or the UNII-3 band to utilize Wi-Fi Direct communication. The bandwidth within the UNII-1 band and the UNII-3 band can have a bandwidth of up to 80 MHz. An electronic device that can occupy both the UNII-1 band and the UNII-2a band can utilize a bandwidth of 160 MHz (e.g., channel 50), but the UNII-2a band may correspond to a DFS channel as described above with reference to FIG. 3. The electronic device (401) and the electronic device (402) cannot utilize the UNII-2a band for Wi-Fi Direct communication, and thus may not be able to utilize a bandwidth of 160 MHz either. The UNII-2c band may also correspond to a DFS channel as described above with reference to FIG. 3. Electronic devices (401) and (402) that wish to perform Wi-Fi Direct communication may not be able to utilize the DFS channel and the 160 MHz bandwidth.

[0099] Referring to FIG. 6, the frequency band and bandwidth utilized by the electronic device (401) and the electronic device (402) during Wi-Fi Direct communication can be confirmed. The electronic device (401) and the electronic device (402) can perform Wi-Fi Direct communication with a bandwidth of 80 MHz in the 5 GHz band (e.g., channel 149). As described above in FIG. 4, the electronic device (401) and the electronic device (402), which each support a bandwidth of 160 MHz, can only perform Wi-Fi Direct communication with a bandwidth of 80 MHz.

[0100]

[0101] FIG. 7 is a diagram illustrating a Wi-Fi direct connection between electronic devices according to one embodiment.

[0102] Referring to FIG. 7, according to one embodiment, each of the electronic device (801) (e.g., the electronic device (102) of FIG. 1) and the electronic device (901) (e.g., the electronic device (101) of FIG. 1) may be a device that supports a Wi-Fi 5 GHz band. Each of the electronic device (801) and the electronic device (901) may be a device that supports a bandwidth of 160 MHz.

[0103] According to one embodiment, the electronic device (801) and the electronic device (901) may utilize a dynamic frequency selection (DFS) channel for Wi-Fi direct communication between each other. The DFS channel may be a channel utilized for military radar, satellite communication, and / or weather radar purposes. Various access points (APs) (e.g., 711 to 714) may exist around the electronic device (801) and the electronic device (901) (e.g., within a coverage area where the APs can be identified). The electronic device (801) and the electronic device (901) may utilize the DFS channel for Wi-Fi direct communication by associating with the AP (712), which is the DFS owner.

[0104] According to one embodiment, in situation (701), the electronic device (801) can perform a connection with an AP (712) that is a DFS owner. The electronic device (901) can perform a connection with the AP (712) or can receive a beacon from the AP (712).

[0111] Referring to FIG. 10, according to one embodiment, the electronic device (801) and the electronic device (901) can check the frequency band (e.g., channel) and bandwidth that can be utilized for Wi-Fi Direct communication. The electronic device (801) and the electronic device (902) can select a channel and bandwidth within the UNII-1 band, the UNII-2a band, and / or the UNII-2c band to perform Wi-Fi Direct communication. The UNII-2a band or the UNII-2c band may correspond to a DFS channel as described above with reference to FIG. 3. The electronic device (801) and the electronic device (901) that wish to perform Wi-Fi Direct communication with a 160 MHz bandwidth of the 5 GHz band can utilize the DFS channel.

[0112] Referring to FIG. 11, according to one embodiment, the frequency band and bandwidth utilized by the electronic device (801) and the electronic device (901) during Wi-Fi Direct communication can be confirmed. The electronic device (801) can maintain a connection with the AP (712), which is a DFS user. The electronic device (801) can communicate with the AP (712) in a bandwidth of 80 MHz in the 5 GHz band (e.g., channel 52).

[0113] According to one embodiment, the electronic device (801) and the electronic device (901) can perform Wi-Fi Direct communication with a bandwidth of 160 MHz in the 5 GHz band (e.g., channel 52). Compared to the bandwidth (e.g., 80 MHz) of the Wi-Fi Direct communication of the electronic devices (401 and 402) of FIG. 4, the bandwidth (e.g., 160 MHz) of the Wi-Fi Direct communication of the electronic devices (801 and 901) can be twice as large. The bandwidth can directly affect the data transmission speed. Compared to the electronic devices (401 and 402), the electronic devices (801 and 901) can have a data transmission speed that is about twice as fast, and the electronic devices (801 and 901) can improve the user experience for the Wi-Fi Direct communication. Below, the detailed operations between electronic devices (801 and 901) are explained case by case.

[0114]

[0115] FIGS. 12 to 20 are flowcharts for explaining a Wi-Fi direct communication method according to one embodiment.

[0116] Referring to FIG. 12, according to one embodiment, the electronic device (801) and the electronic device (901) can perform Wi-Fi direct (Wi-Fi direct) communication with a bandwidth of 160 MHz in the 5 GHz band (e.g., dynamic frequency selection (DFS) channel).

[0117] According to one embodiment, operations 1210 to 1230 may be performed sequentially, but are not necessarily performed sequentially. For example, the order of each operation (1210 to 1230) may be changed, and at least two operations may be performed in parallel. The operations performed by the electronic device (e.g., the electronic device (801) or the electronic device (901)) may include operations performed by a wireless communication circuit (e.g., the wireless communication circuit (810) of FIG. 8 or the wireless communication circuit (910) of FIG. 9) and operations performed by a processor (e.g., the processor (820) of FIG. 8 or the processor (920) of FIG. 9) through the wireless communication circuit.

[0118] According to one embodiment, in operation 1210, the electronic device (801) may perform a connection with an access point (AP) that is a DFS owner. The DFS owner may utilize a DFS channel. The DFS owner may be a device permitted to occupy the DFS channel. The DFS owner may scan for radar signals. If an active radar signal is not detected on the DFS channel, the DFS owner may utilize (e.g., occupy) the DFS channel. The DFS owner may be an access point (AP). Operation 1210 may be triggered by the execution of an application that utilizes Wi-Fi Direct. Operation 1210 may be triggered by a user input to a WSC (Wi-Fi simple configuration) button.

[0119] In one embodiment, the electronic device (801) can determine whether it supports a bandwidth of 160 MHz in the 5 GHz band. The electronic device (801) can perform a passive scan to find a DFS owner. For example, in response to determining that the electronic device (801) supports a bandwidth of 160 MHz in the 5 GHz band, the electronic device (801) can perform a passive scan to find a DFS owner. The electronic device (801) can connect to a DFS owner (e.g., an AP) discovered through the passive scan. If information about an AP that is a DFS owner is already acquired, the electronic device can connect to the AP without a passive scan. The electronic device (801) may be configured to perform a connection with an AP, which is a DFS owner, when extended bandwidth-based communication is required (e.g., when large-capacity data transmission is required (e.g., high-definition video streaming, virtual reality service execution, downloading of large-capacity files, access to large-scale databases)) or when real-time communication is required (e.g., video calling, execution of games requiring high resources). The electronic device (801) may obtain information of the AP (e.g., DFS channel information and bandwidth information) by connecting to the AP.

[0120] According to one embodiment, in operation 1211, the electronic device (901) may perform a connection with an AP that is a DFS owner or receive a beacon from the AP. The electronic device (901) may determine whether it supports a bandwidth of 160 MHz in the 5 GHz band. The electronic device (901) may perform a passive scan to find a DFS owner. For example, in response to determining that the electronic device (901) supports a bandwidth of 160 MHz in the 5 GHz band, the electronic device (901) may perform a passive scan to find a DFS owner. The electronic device (901) may connect with a DFS owner (e.g., an AP) discovered through the passive scan or receive a beacon from the AP. That is, the electronic device (901) may perform a passive scan to receive a beacon from the AP, but in some embodiments, the electronic device (901) may not connect to the AP after receiving the beacon. The electronic device (901) may be configured to perform a connection with an AP that is a DFS owner or to receive a beacon from the AP when extended bandwidth-based communication is required (e.g., when a large amount of data transmission is required (e.g., high-definition video streaming, virtual reality service execution, downloading of large files, access to large databases), or when real-time communication is required (e.g., video calls, execution of games requiring high resources)). The electronic device (901) may obtain information of the AP (e.g., DFS channel information and bandwidth information) by connecting to the AP or receiving a beacon from the AP. Operation 1211 may be triggered by the execution of an application that utilizes Wi-Fi Direct. Operation 1211 may be triggered by a user input to a WSC (Wi-Fi simple configuration) button.

[0121] According to one embodiment, in operation 1220, the electronic device (801) and the electronic device (901) can perform a Wi-Fi Direct connection based on a DFS channel.

The electronic device (801) and the electronic device (901) may exchange a group owner negotiation request and a group owner negotiation response. The electronic device (801) may transmit a group owner negotiation confirm to the electronic device (901). The electronic device (801) connected to the AP may act as a group owner, and the electronic device (901) receiving a beacon from the AP may act as a group client. When both the electronic devices (801 and 901) are connected to the AP, any electronic device may act as the group owner. The electronic device (801) and the electronic device (901) may compare their respective group owner intents to determine the group owner. An electronic device (801) connected to an AP may have a higher group owner intent than an electronic device (901) receiving a beacon from the AP. For example, if both electronic devices (801 and 901) are connected to an AP and the group owner intent of the electronic device (801) and the group owner intent of the electronic device (901) are the same, the group owner may be determined randomly. For example, even if both electronic devices (801 and 901) are connected to an AP, the group owner intents of the electronic devices (801 and 901) may be different. Each of the electronic devices (801 and 901) may have a different group owner intent based on the group owner intent policy of the upper application and / or the state (e.g., current state) of the electronic device.Even if both electronic devices (801 and 901) are connected to the AP, the electronic device with a higher group owner intent can act as the group owner. For example, each electronic device can act as the group owner if its group owner intent is greater than that of the other electronic device or if no other electronic device is connected to the AP. Each electronic device can act as the group client if another electronic device is connected to the AP and its group owner intent is less than that of the other electronic device.

If an active radar signal is not detected on the DFS channel, the DFS owner may utilize (e.g., occupy) the DFS channel. The DFS owner may be an access point (AP). Operation 1310 may be triggered by the execution of an application that utilizes Wi-Fi Direct. Operation 1310 may be triggered by a user input to a WSC (Wi-Fi simple configuration) button.

[0269] Fig. 25 is a diagram for explaining NAN communication according to one embodiment.

[0270] Referring to FIG. 25, according to one embodiment, a neighbor awareness networking (NAN) cluster (2500) may include one or more electronic devices (e.g., electronic device (2501), electronic device (2502), electronic device (2503), and / or electronic device (2504)). Within the NAN cluster (2500), the electronic devices (2501, 2502, 2503, and 2504) (e.g., 2501 to 2504)) may communicate with each other via NAN (or NAN protocol). The NAN cluster (2500) may mean a set of one or more electronic devices (2501 to 2504) that form a proximity network so that the electronic devices (2501 to 2504) can transmit and receive data among themselves.

[0271] According to one embodiment, the electronic devices (2501 to 2504) may be devices that support NAN, a low-power discovery technology, and may be referred to as NAN devices (or NAN terminals). In addition, the electronic devices (2501 to 2504) may operate in frequency bands of 2.4 GHz, 5 GHz, and / or 6 GHz, and may exchange signals based on the Institute of Electrical and Electronic Engineers (IEEE) 802.11 protocol (e.g., 802.11 a / b / g / n / ac / ax / be). The electronic devices (2501 to 2504) may exchange signals in a unicast, broadcast, and / or multicast manner.

[0272] According to one embodiment, electronic devices (2501 to 2504) may form a single NAN cluster (2500) by transmitting and receiving beacons (e.g., discovery beacons). Electronic devices (2501 to 2504) within the NAN cluster (2500) may be time-synchronized and channel-synchronized.

[0273] According to one embodiment, a discovery beacon may be a beacon signal for discovering an electronic device that can form a cluster (e.g., a NAN cluster (2500)) for a proximity network. In addition, the discovery beacon may be a signal transmitted so that other electronic devices (not shown) that have not joined the NAN cluster (2500) can discover the NAN cluster (2500). The discovery beacon may be a signal for notifying the electronic device of the existence of the NAN cluster (2500). An electronic device (not shown) that has not joined the NAN cluster (2500) can perform a passive scan to receive the discovery beacon and discover and join the NAN cluster (2500) based on the received discovery beacon.

[0274] According to one embodiment, a discovery beacon may include information necessary for synchronization with a NAN cluster (2500). That is, the discovery beacon may include information that enables an electronic device outside the NAN cluster to join and synchronize with the NAN cluster (2500). For example, the discovery beacon may include a frame control (FC) field indicating a function of the signal (e.g., a beacon), a broadcast address, a media access control (MAC) address of a transmitting electronic device, a cluster identifier (ID), a sequence control field, a time stamp for a beacon frame, a beacon interval indicating a transmission interval of the discovery beacon, and / or capability information for the transmitting electronic device. In addition, the discovery beacon may further include at least one proximity network (or cluster) (e.g., the NAN cluster (2500)) related information element. Information related to proximity networks can be referred to as attribute information.

[0275] According to one embodiment, the electronic devices (2501 to 2504) can transmit and receive signals (e.g., synchronous beacons), service discovery frames (SDFs), and / or NAN action frames (NAFs) within a synchronized time duration (e.g., discovery window (DW)). That is, the discovery window (DW) can be a period of time during which an electronic device in a NAN cluster transmits and receives signals with other electronic devices in the NAN cluster. That is, an electronic device in a NAN cluster may not transmit or receive signals with other electronic devices in the NAN cluster outside of the DW time frame. The DW for each electronic device in the NAN cluster can be synchronized, so that the DW for each electronic device in the NAN cluster can be the same. That is, the start time, end time, and total duration of the DW can be the same for all electronic devices in the NAN cluster. For example, the electronic devices (2501 to 2504) can synchronize with each other time clocks (time clocks). The clocks are synchronized so that they can exchange synchronization beacons, SDFs, and / or NAFs at the same time within the synchronized DW.

[0276] According to one embodiment, a synchronization beacon may be a signal for maintaining synchronization between synchronized electronic devices (2501 to 2504) within a NAN cluster (2500). The synchronization beacon may be periodically transmitted and received per DW to continuously maintain time synchronization and channel synchronization of the electronic devices (2501 to 2504) within the NAN cluster (2500). That is, each electronic device within the NAN cluster may transmit and / or receive multiple synchronization beacons during each DW. The synchronization beacon may be transmitted by a designated electronic device among the electronic devices (2501 to 2504) within the NAN cluster (2500). The electronic device transmitting the synchronization beacon may include or be referred to as an anchor master device, a master device, or a non-master sync device defined in the NAN standard.

[0277] According to one embodiment, the synchronization beacon may include information necessary for synchronization of electronic devices (2501 to 2504) within a NAN cluster (2500). That is, the synchronization beacon may include information necessary for electronic devices within a NAN cluster to synchronize with each other, so that a plurality of or all electronic devices within the NAN cluster may be synchronized. For example, the synchronization beacon may include one or more of an FC field indicating a function of a signal (e.g., a beacon), a broadcast address, a MAC address of a transmitting electronic device, a cluster identifier, a sequence control field, a timestamp for a beacon frame, a beacon interval indicating an interval between starting points of DW, and capability information for the transmitting electronic device. The synchronization beacon may further include at least one proximity network (or cluster) (e.g., NAN cluster (2500)) related information element. The proximity network related information may include contents for a service provided via a proximity network.

[0278] In one embodiment, the SDF may represent a signal for exchanging data over a proximity network (or cluster) (e.g., a NAN cluster (2500)). The SDF represents a vendor-specific public action frame and may include various fields. For example, the SDF may include a category or action field, and may further include information related to at least one proximity network (e.g., a NAN cluster (2500)).

[0279] According to one embodiment, electronic devices (2501 to 2504) included in a NAN cluster (2500) can transmit and receive NAFs within a DW. For example, the NAF may include information related to NDP (NAN data path) setup for performing data communication in the DW, information for schedule update, and / or information for performing NAN ranging (e.g., fine timing measurement (FTM) NAN ranging). The NAF may be for controlling the schedule of wireless resources for coexistence of NAN operations and non-NAN operations (e.g., Wi-Fi Direct, mesh, IBSS, WLAN, Bluetooth, NFC). The NAF may include time and channel information available for NAN communication.

[0280] According to one embodiment, the NAN operation mode field exchanged during the NDP setup process may include fields as in Table 7, and the channel bitmap may be configured as in Table 8.
