Description

Electronic device for scheduling data link and method of operating the same {ELECTRONIC DEVICE FOR SCHEDULING OF DATA LINK AND METHOD FOR THE SAME}

Various embodiments of the present invention relate to an electronic device for scheduling a data link and a method of operating the same.

Due to the advancement of information and communication technology and semiconductor technology, various electronic devices are being used. Electronic devices can provide various types of proximity services using low-power discovery technology. Proximity service may refer to a communication function in which nearby electronic devices quickly exchange data through a proximity network. For example, the proximity service is a low power proximity service using BLE (Bluetooth low energy) beacons, or a low power short-range communication technology based on wireless local area network (WLAN) (e.g. It may include a low-power proximity service based on neighbor awareness networking (NAN) and/or Wi-Fi aware (hereinafter referred to as 'NAN').

NAN-based low-power proximity service can represent a communication function that exchanges data by forming a proximity network that changes dynamically according to the movement of electronic devices. Electronic devices included in the cluster announce the existence of the cluster within a time duration (or communication section) (e.g., discovery window (DW)) synchronized with each other or perform discovery for synchronization. A signal (e.g., beacon) and a service discovery frame (SDF) may be transmitted and/or received. As an example, a cluster may represent a set of electronic devices that form a proximity network.

Electronic devices included in the cluster may set up (or create) a NAN data path (NDP) to perform NAN communication in a section other than the discovery window (DW). For example, an electronic device included in a cluster may set a time slot (e.g., further available windows (FAWs)) for data transmission in the section between discovery windows through scheduling with an external electronic device. The electronic device may transmit and/or receive data with an external electronic device through a time interval set between discovery windows.

An electronic device can support multiple NAN data paths simultaneously. For example, an electronic device may transmit and/or receive data simultaneously with a plurality of external electronic devices.

The electronic device may set an NDP based on the first frequency band (e.g., approximately 6 GHz band) through scheduling with the first external electronic device. The electronic device may determine the first frequency band as an effective frequency band (or effective channel) based on the NDP setting with the first external electronic device.

The electronic device may set an NDP with the second external electronic device based on detection of a second external electronic device for data transmission while transmitting data to the first external electronic device through NDP. If the second external electronic device does not support the first frequency band, the electronic device updates the NDP (or NDP scheduling) with the first external electronic device to the second frequency band (e.g., about 5 GHz) and performs scheduling through scheduling. An NDP based on a second frequency band with a second external electronic device may be set. For example, since the electronic device cannot use the first frequency band and the second frequency band simultaneously due to the structure of the communication circuit, NDP (or NDP scheduling) with the first external electronic device is performed in the second frequency band (e.g., approx. 5 GHz). The electronic device may delay NDP setup with the second external electronic device based on NDP (or NDP scheduling) update with the first external electronic device.

Various embodiments of the present invention disclose an apparatus and method for NDP scheduling in an electronic device.
