Further, the present invention presents even a method for improving quality of experience (QoE) of the service by providing the MBMS service through the multicast bearer and the unicast bearer simultaneously. According to the present invention, MBMS services of various service qualities can be provided depending on wireless quality of a terminal or the capability of the terminal at the time of providing the MBMS service. | 2012-06-28 |
| 20120163275 | METHOD OF PROVIDING WIRELESS COMMUNICATION BETWEEN VEHICLE AND ROADSIDE AND VEHICLE WIRELESS COMMUNICATION DEVICE USING THE SAME - Disclosed herein is a method of providing vehicle wireless communication. In the method, a vehicle receives hand-over-related link information, which includes slot request information about slots requested by a vehicle to a roadside wireless communication device for hand-over of the vehicle, from a central control server. A hand-over preparation message, which includes the hand-over-related link information, is send to a vehicle wireless communication device connected to the vehicle. It is determined that the vehicle completed preparation for performance of the hand-over when a response message to the hand-over preparation message is received from the vehicle wireless communication device. Slots are allocated in consideration of the hand-over-related link information. Beacon frames, which include slot allocation information about the allocated slots, are transmitted to the vehicle wireless communication device. Accordingly, the vehicle wireless communication device and the roadside wireless communication device can reliably perform communication without interruption. | 2012-06-28 |
| 20120163276 | METHOD AND APPARATUS FOR ALLOCATING MULTICAST RESOURCE AND METHOD AND APPARATUS FOR RECEIVING MULTICAST RESOURCE ALLOCATION INFORMATION - A method of allocating a multicast resource to a multicast group for a multicast communication in a base station is provided. The base station persistently allocates the multicast resource to the multicast group, generates a MAP IE including allocation information of the multicast resource, an allocation period indicating a period in which the multicast resource is allocated and a lifetime in which allocation of the multicast resource is maintained, and transmitting the MAP IE to the multicast group. | 2012-06-28 |
| 20120163277 | METHOD AND APPARATUS FOR ESTABLISHING MULICAST CONNECTION - A method of establishing a multicast connection is provided. A mobile station transmits a registration request message for a discovery of a multicast service to the base station, and receives a registration response message from the base station in response to the registration request message. The mobile station exchanges a DSA request message and a DSA response message to the DSA request message with the base station, for a multicast connection on the multicast service. The mobile station receives a downlink control channel including allocation information of multicast resource from the base station. | 2012-06-28 |
| 20120163278 | METHOD FOR PERFORMING DIRECT COMMUNICATION BETWEEN TERMINALS - A method for performing direct communication, by a first terminal, between terminals, includes transmitting a control message for a direct communication resource allocation to at least one second terminal through a first region included in a direct communication resource, transmitting synchronization information to at least one second terminal through a second region included in the direct communication resource, and transmitting a data packet to at least one second terminal through a third region included in the direct communication resource. | 2012-06-28 |
| 20120163279 | COMMUNICATION APPARATUS, COMMUNICATION TERMINAL APPARATUS, COMMUNICATION SYSTEM, AND COMMUNICATION METHOD - A power-consumption-information collecting apparatus ( | 2012-06-28 |
| 20120163280 | PHYSICAL LAYER COMMUNICATION PROTOCOL FOR USE IN WIRELESS NETWORKS WITH RELAYS - In some embodiments, a relay station comprises a baseband processor, an RF modulator/demodulator coupled to the baseband processor to modulate/demodulate data for communication within a predetermined frequency range, and a control module to implement a femto transmission-free zone in at least one of a time domain or a frequency domain and in which the relay station does not transmit data. Other embodiments may be described. | 2012-06-28 |
