Abstract: Disclosed is an electronic device. In addition, it is possible to implement various embodiment understood through the present disclosure. The electronic device transmits a first signal in a first frequency band including at least one of a synchronization beacon frame, a service discovery frame, or an action frame based on an NAN protocol at a first interval for a series of first durations, and transmits a second signal in a second frequency band including at least one of the synchronization beacon frame, the service discovery frame, or the action frame based on the NAN protocol at a second interval for a series of second durations.

Abstract: An electronic device and a method for forming a Wi-Fi direct group thereof are provided. The electronic device may include a housing, a wireless communication circuit, at least one processor, and a memory. The memory may cause the at least one processor to receive a first list of wireless channels for a direct connection from a first external device, establish, as a group owner, a first wireless connection with the first external device acting as a group client by using a first channel selected from the first list, listen for a probe request over a second channel every selected time period, receive the probe request from a second external device during the selected time period through the second channel, transmit a probe response to the second external device, receive a second list of wireless channels for a direct connection from the second external device, and select a third channel.

Abstract: A method and apparatus allocates an IP address between terminals in a wireless communication network in which terminals directly communicate with each other in a wireless scheme without an AP. The method for allocating an Internet Protocol (IP) address of a wireless terminal capable of performing P2P communication, includes a discovery step of discovering at least one external terminal capable of performing the P2P communication and connecting with the at least one discovered external terminal by the wireless terminal; and a negotiation step of negotiating and determining with the external terminal which external terminals become a group owner and a group client in a P2P group, respectively by the wireless terminal. One of the discovery step and the negotiation step includes transmitting an IP address to be allocated to the group client to the external terminal from the wireless terminal.
