摘要:
Disclosed is a method for a first terminal to perform direct communication between terminals, the method including performing direct communication with at least one second terminal by using resources allocated for direct communication between terminals, the resources including a synchronization channel used for frequency synchronization and time synchronization between terminals, and the synchronization channel including a synchronization channel preamble used for at least one of preamble detection, time offset estimation, frequency offset estimation, and channel estimation.

摘要:
A signaling method of a first terminal for direct communication between terminals includes transmitting a link establishment request message for establishing a direct communication link including flow information to a second terminal, receiving a link establishment response message for establishing a direct communication link including flow information from the second terminal, and establishing a direct communication link between the first terminal and the second terminal.
摘要:
A method in which a first terminal supports direct communication using infracommunication includes setting at least one direct communication link with at least one second terminal, setting at least one traffic connection with a base station, and forwarding data that is transmitted through the at least one direct communication link from the at least one second terminal to the at least one traffic connection or forwarding data that is transmitted through the at least one traffic connection from the base station to the at least one direct communication link.
摘要:
A first terminal for performing direct communication between terminals includes: a radio frequency (RF) unit; and a processor, the processor being adapted to perform direct communication with at least one second terminal by using resources allocated for direct communication between terminals, wherein the resources are divided into a first slot region and a second slot region, the first slot region including a synchronization channel containing synchronization information for direct communication between terminals, a dedicated channel for transmitting direct communication data between terminals, and a supplementary channel one-to-one mapped with the dedicated channel, and the second slot region including the dedicated channel and the supplementary channel.
摘要:
A method of performing communication of a terminal includes the terminal transmitting state information thereof to a base station, and the terminal receiving a mode change request from the base station when the terminal is selected by the base station.
摘要:
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.
摘要:
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.

摘要:
In a method of managing a multicast service, a mobile station receives a message including multicast service flow update information from a base station that belongs to a multicast group zone including a base station set having at least one base station. The mobile station updates a parameter associated with a multicast service flow of the multicast service based on the multicast service flow update information. The multicast service flow update information includes a new multicast group zone ID, current multicast service identification information, and new multicast service identification information mapped to the current multicast service identification information.
