[0026] In describing the embodiments, descriptions of technical details that are well known in the technical field to which the present disclosure pertains and are not directly related to the present disclosure will be omitted.

[0033] In this disclosure, the terms "Wireless Local Area Network (WLAN)" and "Wi-Fi" may be used interchangeably. For convenience of explanation, this disclosure describes a WLAN system including at least one Access Point (AP) and at least one Station (STA), but embodiments of the present disclosure are also applicable to other WLAN systems, including, for example, multiple WLANs, peer-to-peer (or independent basic service set) systems, Wi-Fi Direct systems, and / or hotspots.

[0034] Wi-Fi CERTIFIED Wi-Fi Aware TM Wi-Fi Aware is a technology that extends Wi-Fi capabilities by enabling rapid discovery, connection, and data exchange with other Wi-Fi devices without the need for traditional network infrastructure, an Internet connection, or a GPS signal. Wi-Fi Aware can enable devices to discover and connect directly to each other without requiring any other type of connection. Wi-Fi Aware can also be referred to as neighbor awareness networking (NAN).

[0035] Wi-Fi Aware networking can operate by forming clusters with nearby devices or by creating a new cluster if the device is the first in the area. Applications can use the Wi-Fi Aware application programming interface (API) to communicate with the Wi-Fi Aware system service, which manages the device's Wi-Fi Aware hardware. For example, Wi-Fi Aware network connections can support higher throughput at longer distances than Bluetooth connections. For example, Wi-Fi Aware network connections can be useful for apps that share large amounts of data between users, such as photo sharing apps.

[0036] The operating principles of the present disclosure are described in detail below with reference to the attached drawings.

Therefore, their definitions should be based on the overall content of this specification.

[0037] FIG. 1 illustrates a communication system (100) including an access point (AP) and a station (STA).

[0038] Referring to FIG. 1, a communication system (100) may include a wireless local area network (WLAN) comprised of a plurality of wireless access points (APs) (110, 115) and a plurality of stations (STAs) (120, 125). For convenience of explanation, only two access points (APs) (110, 115) and two stations (STAs) (120, 125) are illustrated in FIG. 1, but the WLAN may include any number of access points (APs) and any number of stations (STAs).

[0039] A station (STA) (120, 125) may include at least one transceiver, at least one processor, and / or at least one memory. The at least one memory may include a non-transitory computer-readable medium storing instructions for an access point (AP) (110, 115) to perform operations according to embodiments of the present disclosure. The station (STA) (120, 125) may be implemented as an electronic device or a mobile device.

[0040] An access point (AP) (110, 115) may be a device that enables one or more stations (STAs) to connect to a network (e.g., a local area network (LAN), a wide area network (WAN), a metropolitan area network (MAN), and / or the Internet) using Wi-Fi, Bluetooth, or any other suitable communication technology. The access point (AP) (110, 115) may include at least one transceiver, at least one processor, and / or at least one memory. The at least one memory may include a non-transitory computer-readable medium storing instructions for the access point (AP) (110, 115) to perform operations according to embodiments of the present disclosure. According to one embodiment, the access point (AP) (110, 115) may be implemented as a hardware device or a software device.

[0041] At least one transceiver included in an access point (AP) (110, 115) and / or a station (STA) (120, 125) may include a Wi-Fi transceiver, a Bluetooth transceiver, a cellular transceiver, and / or other suitable radio frequency (RF) transceiver for transmitting and / or receiving signals. Each transceiver may communicate with other wireless devices in distinct operating frequency bands and / or using distinct communication protocols. For example, a Wi-Fi transceiver may communicate within a 2.4 GHz frequency band and / or a 5 GHz frequency band in accordance with the IEEE 802.11 standard.

[0042] The first station (120) may be connected to the first access point (110) via a first channel (e.g., channel 36 of 5 GHz). For example, the first access point (110) may transmit a signal at a preset interval (e.g., 120 TU) during a preset time period (e.g., 1200 TU (time units)).

[0043] A second station (125) may be connected to a second access point (115) via a second channel (e.g., channel 52 of 5 GHz). For example, the second access point (115) may transmit a signal at preset intervals (e.g., 70 TU) during a preset time period (e.g., 1000 TU).

[0044] The first station (120) can perform Wi-Fi Aware (or NAN) communication with the second station (125) through a third channel (e.g., channel 149 of 5.GHz).

[0045] In the present disclosure, the channel used by the station (120, 125) when communicating with the access point (110, 115) may be referred to as an AP channel, and the channel used when communicating between the stations (120, 125) may be referred to as a Wi-Fi Aware channel (or aware channel).

[0046] Figure 2a illustrates the operation of an access point (AP) and a station (STA) for establishing a Wi-Fi connection.

[0047] Referring to FIG. 2A, a station (220) may transmit (or broadcast) a probe request message to an access point (210) (S201). For example, the probe request message may include information regarding at least one communication capability supported by the station (220).

[0048] The access point (210) may transmit a probe response message in response to the probe request message (S202). Upon receiving the probe response message, the station (220) may transmit an authentication request message to the access point (210) (S203). The access point (210) may transmit an authentication response message to the station (220) in response to the authentication request message (S204), and the authentication procedure between the access point (210) and the station (220) may be completed.

[0049] Once the authentication process is completed, the station (220) can transmit an association request message to the access point (210) (S205). For example, the association request message can include information regarding at least one capability (e.g., according to the IEEE 802.11 standard) to be used for data communication between the station (220) and the access point (210). The access point (210) can generate an association ID for the station (220) and transmit an association response message to the station (220) (S206).

[0050] Figure 2b illustrates the operation of the first station and the second station for Wi-Fi Aware connection.

[0051] Referring to FIG. 2B, when the first station (230) and / or the second station (240) decide to proceed with a Wi-Fi Aware (or NAN) connection, the first station (230) may transmit at least one discovery beacon message to the second station (240) for synchronization (S211, S212). The first station (230) may transmit a synchronization beacon message to the second station (240) (S213). The second station (240) may scan at least one discovery beacon message and / or synchronization beacon message and perform a synchronization procedure (or operation) with the first station (230).

[0052] The first station (230) transmits an SDF (service discovery frame) publish message to the second station (240) for service discovery (S214), and the second station (240) can transmit an SDF follow-up message corresponding to the SDF publish message to the first station (230) (S215).

[0053] The second station (240) transmits a data path request message to the first station (230) for NDP (NAN data path) setup (S216), and the first station (230) can transmit a data path response message to the second station (240) (S217). The second station (240) transmits a data path confirm message to the first station (230) (S218), and the first station (230) can transmit a data path key installment message to the second station (240) (S219). When the NDP setup is completed, the first station (230) and the second station (240) can establish a NAN connection (S220).

[0054] According to one embodiment, the first station (230) and the second station (240) may exchange information regarding quality of service (QoS) prior to the NDP setup procedure. According to one embodiment, the information regarding QoS may be included in a QoS field of an SDF message (e.g., an SDF Publish message, an SDF subscribe message, and / or an SDF follow-up message).

[0055] According to one embodiment, the first station (230) and the second station (240) may exchange time synchronization function (TSF) information during a service discovery procedure (e.g., S214 and / or S215) to optimize AP and Wi-Fi Aware scheduling. According to one embodiment, the first station (230) and / or the second station (240) may use the exchanged TSF information to adjust and / or reduce an AP interval (or period) for communication with an access point (AP). For example, the AP interval may be reduced from 8 slots to 5 slots based on the TSF information.

[0056] In one embodiment, if neither the first station (230) nor the second station (240) transmits and / or receives traffic requiring high QoS when communicating with an access point, more time resources may be allocated to Wi-Fi Aware communication between the first station (230) and the second station (240). In one embodiment, more time resources may be allocated to Wi-Fi Aware communication to perform one-hop data transmission (e.g., QuickShare function) between the first station (230) and the second station (240).

[0057] FIG. 3 is a diagram for explaining time resource allocation for AP communication and Wi-Fi Aware communication of a station according to one embodiment of the present disclosure.

[0058] Referring to FIG. 3, the communication system may include a first access point (310), a first station (320) connected to the first access point (310), a second access point (315), and a second station (325) connected to the second access point (315). At this time, the first station (320) and the second station (325) may perform Wi-Fi Aware communication.

[0059] The first access point (310) can broadcast a plurality of beacons (301-311) through the first AP channel, and the second access point 2 (315) can broadcast a plurality of beacons (321-339) through the second AP channel. In the present disclosure, the beacons broadcast by the access points may also be referred to as AP beacons.

[0060] The first access point (310) can broadcast each of a plurality of beacons (301 to 311) at a set cycle (e.g., 120 TU) through the first AP channel. The second access point 2 (315) can broadcast each of a plurality of beacons (321 to 339) at a set cycle (e.g., 70 TU) through the second AP channel.

[0061] According to one embodiment, the beacon broadcast by the first access point (310) and / or the second access point (315) may include at least one of identity information such as a service set identifier (SSID) and a basic service set identifier (BSSID), frequency information related to transmission and reception of data, and frequency type information.

[0062] According to one embodiment, 1 slot, which is a time resource allocation unit for AP communication and Wi-Fi Aware communication, may be set to 16 TUs. In FIG. 3, for example, 8 slots (= 128 TUs) may be allocated to each of the AP sections (340, 345) for AP communication, and for example, 24 slots (= 384 TUs) may be allocated to each of the Aware sections (350, 355) for Wi-Fi Aware communication. According to one embodiment, more time resources may be allocated to the Aware sections (350, 355) for Wi-Fi Aware communication than to the AP sections (340, 345) depending on the traffic status of the AP connection (e.g., whether the traffic is sensitive to throughput and / or delay).

[0063] The first station (320) can receive a beacon (301) broadcast by the first access point (310) during the first AP period (340). The first station (320) can perform Wi-Fi Aware communication with the second station (325) during the first Aware period (350) and cannot receive the beacons (303, 305, 307) broadcast by the first access point (310). The first station (320) can receive beacons (309, 311) broadcast by the first access point (310) during the second AP period (345). The first station (320) can perform Wi-Fi Aware communication with the second station (325) during the second Aware period (355).

[0064] The second station (325) can receive two beacons (321, 323) broadcast by the second access point (315) during the first AP period (340). The second station (325) performs Wi-Fi Aware communication with the first station (320) during the first Aware period (350) and may not receive the beacons (325 to 333) broadcast by the second access point (315). The second station (325) can receive two beacons (335, 337) broadcast by the second access point (315) during the second AP period (345). The second station (325) performs Wi-Fi Aware communication with the first station (320) during the second Aware period (355) and may not receive one beacon (339) broadcast by the second access point (315).

[0065] In FIG. 3, each of the first station (320) and the second station (325) may not receive at least one AP beacon during Wi-Fi Aware communication.

[0066] FIG. 4 illustrates a process in which electronic devices perform adaptive NAN scheduling when conditions are satisfied according to one embodiment of the present disclosure.

[0067] In FIG. 4, a first electronic device and a second electronic device may perform adaptive NAN scheduling (also referred to as ANS) after NDP (NAN data path) setup. According to an embodiment, the first electronic device and the second electronic device may exchange their BSSIDs (Basic Service Set Identifiers) through SDF before NDP setup. According to an embodiment, the BSSID may be an identifier or network ID of a set size (e.g., 48 bits) that identifies a Basic Service Set. According to an embodiment, if the BSSID of the first electronic device and the BSSID of the second electronic device are different from each other, each of the first electronic device and the second electronic device may start monitoring AP traffic.

In operation 405, the first electronic device can compare the BSSID of the first electronic device with the BSSID of the second electronic device through the framework and determine whether the AP connected to the first electronic device and the AP connected to the second electronic device are different from each other. In operation 407, if the AP connected to the first electronic device and the AP connected to the second electronic device are different from each other, the first electronic device can activate an adaptive NAN scheduling (ANS) function (or a procedure related to ANS).

[0070] In operation 409, the second electronic device can transmit the BSSID of the first electronic device from the firmware in the second electronic device to the framework. In operation 411, the second electronic device can compare the BSSID of the first electronic device and the BSSID of the second electronic device through the framework and determine whether the AP connected to the first electronic device and the AP connected to the second electronic device are different from each other. In operation 413, if the AP connected to the first electronic device and the AP connected to the second electronic device are different from each other, the second electronic device can activate an adaptive NAN scheduling (ANS) function (or a procedure related to ANS).

[0071] In operation 415, the first electronic device and the second electronic device may perform NDP setup related procedures. In operation 417, the first electronic device and the second electronic device may exchange their respective beacon intervals and TSFs for their respective connected APs.

[0072] In operation 419, the first electronic device may monitor instant AP traffic and / or averaged AP traffic. The first electronic device may track the traffic load of the AP through the framework. In operation 421, the first electronic device may determine whether a condition for activating the adaptive NAN scheduling (ANS) function is satisfied based on the result of operation 419.

[0073] In operation 423, the second electronic device may monitor instant AP traffic and / or averaged AP traffic. The second electronic device may track the traffic load of the AP through the framework. In operation 425, the second electronic device may determine, based on the result of operation 423, that a condition for activating the adaptive NAN scheduling (ANS) function is satisfied. According to one embodiment, if the traffic condition is satisfied, the second electronic device may initiate a random backoff before transmitting the request message to avoid simultaneous transmission of the request message.

[0074] In operation 427, the second electronic device may transmit a request message (Request scheduling update) to the first electronic device, which includes information (or bitmaps) for allocating time intervals for AP communication and time intervals for Wi-Fi Aware communication, respectively. In operation 429, the first electronic device may transmit a response message (Response scheduling update) to the second electronic device, which includes information (or bitmaps) for allocating time intervals for AP communication and time intervals for Wi-Fi Aware communication, respectively.

[0075] In operation 431, the second electronic device may transmit a confirmation message (Confirm Scheduling Update) to the first electronic device, which includes information (or a bitmap) for allocating time intervals for AP communication and time intervals for Wi-Fi Aware communication, respectively. Upon transmitting and receiving the confirmation message, the first electronic device and the second electronic device may perform ANS based on the updated allocation information.

[0076] In operation 433, the first electronic device may update the time interval scheduling for Wi-Fi Aware communication using firmware. In operation 435, the second electronic device may update the time interval scheduling for Wi-Fi Aware communication using firmware. According to one embodiment, the scheduling policy for Wi-Fi Aware communication may be different based on the beacon interval of each of the APs connected to the first electronic device and the second electronic device, and a bitmap may be set to ensure beacon reception by each electronic device.

[0077] FIG. 5 illustrates a process in which electronic devices perform adaptive NAN scheduling when conditions are satisfied at different times according to one embodiment of the present disclosure.
