Abstract:
A method of managing a resource is provided by a base station. The base station allocates a resource to a terminal, and generates a downlink control channel including information of the allocated resource and a transmission time of a next downlink control channel. Further, the base station transmits the downlink control channel to the terminal.
Abstract:
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.
Abstract:
A permutated channel structure based on a block structure in talk-around direct communication is provided. A dedicated subchannel interferes with only one adjacent dedicated subchannel, even with a large synchronization error, by permutating the dedicated subchannels by cyclic shifts, whereby diversity gain can be maintained and interference between adjacent channels can be minimized.
Abstract:
In a direct communication between terminals, a terminal transmits a synchronization channel preamble part after transmitting a synchronization channel message part including synchronization information. The terminal receives a dedicated channel including a direct communication packet after transmitting the synchronization channel preamble part. A transition time gap for switching from transmission to reception may be inserted to an end of the synchronization channel preamble part.
Abstract:
Disclosed are operation methods of communication node supporting direct communications in network. The operation method may comprise generating control information which includes parameters used for transmitting and receiving data; transmitting, to a second UE, the control information through a physical sidelink control channel (PSCCH); and transmitting, to the second UE, the data through a physical sidelink shared channel (PSSCH) based on the parameters. Therefore, a performance of the network can be enhanced.
Abstract:
An operation method of a first communication node, which controls a plurality of communication nodes included in a mobile xhaul network supporting mobility, may comprise performing an attach procedure between the first communication node and a second communication node among the plurality of communication nodes; configuring a path for communications between the second communication node and a third communication node for which attach procedure has been completed among the plurality of communication nodes; and supporting communications of the second communication node and the third communication node using the configured path.
Abstract:
Referring to FIG. 4, if the direct communication terminal 120, among the direct communication terminals 120 and 130 receiving a downlink multicast service from the base station 200 through the forwarding terminal 110, wants to be a talker, the direct communication terminal 120 performs a unicast connection establishment procedure with the forwarding terminal 110, in order to transmit an uplink unicast packet.
Abstract:
A relay, a terminal, and a communication method of the same are provided. The terminal acting as a relay receives a message including scan duration information from a superordinate HR-BS, and the terminal transmits a message including the scan duration information to a subordinate HR-MS. The terminal receives an A-preamble from the superordinate HR-BS according to the scan duration information.
Abstract:
A mobile relay station (RS) and a handover method thereof are provided. When it is determined that a mobile RS performs handover from a superordinate base station (BS) to a target BS, information indicating admission of handover is received from the superordinate BS. The mobile RS transmits a service unavailability section to a subordinate terminal, whereby the subordinate terminal is prevented from performing handover to a different BS or a different RS.
Abstract:
A handover method performed by a terminal in a non-terrestrial network may comprise transmitting a measurement report including measurement results for neighbor cells to a serving satellite base station; receiving, from the serving satellite base station, connection configuration information for at least one target base station candidate and information on an activation time when the connection configuration information for the at least one target base station candidate is activated; and performing a handover to a first target base station candidate among the at least one target base station candidate based on information received from the at least one target base station candidate at the activation time.
