If one of the stations on the list is in the area and would like to connect to the AP role, it can complete the connection process using information in the response message. | 2015-07-23 |
20150208452 | METHOD AND APPARATUS FOR TRANSMITTING DEVICE-TO-DEVICE RELATED MESSAGE IN WIRELESS COMMUNICATION SYSTEM - A method and apparatus for establishing a device-to-device (D2D) connection in a wireless communication system is provided. A first mobile device transmits a D2D related message including an identity of a second mobile device, which is connected with the first mobile device, to a network. Or, a first mobile device receives a D2D related message including an identity of a second mobile device, which is connected with the first mobile device, from a network. | 2015-07-23 |
20150208453 | MOBILE COMMUNICATION SYSTEM - A mobile communication system that supports Device to Device (D2D) communication comprises a user terminal that transmits a reference signal for D2D that is used for channel estimation in at least the D2D communication, and the reference signal for D2D is further used for discovering another user terminal to be a communication partner of the D2D communication. | 2015-07-23 |
20150208454 | METHOD AND APPARATUS FOR DISCOVERING DEVICE BASED ON LOCATION INFORMATION - A Wireless Fidelity (Wi-Fi) Direct connection method for a User Equipment (UE) is provided. The method includes receiving a probe signal from at least one device; comparing location information in the probe signal with location information of the UE; and performing the Wi-Fi Direct connection for the at least one device transmitting the probe signal including location information that is the same as that of the UE. In addition, a method of supporting a Wi-Fi Direct connection for a wireless Access Point (AP) is provided. The method includes receiving common location information from at least one gateway; and transmitting unique identification information of the wireless AP and the common location information to at least one Wi-Fi Direct support device, wherein the unique identification information and the common location information are used to create location information, which is included in a probe signal, in the Wi-Fi Direct support device. | 2015-07-23 |
20150208455 | Wireless communication device and method capable of peer-to-peer interconnection - The present invention discloses a wireless communication device capable of establishing peer-to-peer connection passively or actively. The device conforms to an IEEE 802.11 standard, and comprises: a control block, a transmission circuit and a reception circuit. When the device intends to passively establish peer-to-peer connection, said control block generates a local-end peer-to-peer connection message which includes a local-end group owner intent but isn't generated in response to any known/detected device; said transmission circuit broadcasts a local-end peer-to-peer connection packet according to the message; and said reception circuit receives a connection-end peer-to-peer connection request from a connection-end for the first time after broadcasting the message, wherein the request includes a connection-end group owner decision related to the local-end group owner intent. Accordingly, after receiving the request, the wireless communication device functions as a master or a slave according to the decision, and then establishes the peer-to-peer connection with the first connection-end. | 2015-07-23 |
20150208456 | METHOD, DEVICE, AND SYSTEM FOR MULTIPLE USERS COOPERATIVE COMMUNICATION - Embodiments of the present invention disclose a method for multiple users cooperative communication.
