Abstract: The present disclosure provides a beam selection method and a network element. The network element includes a first network element in a communication network, including: a receiving unit configured to receive measurement results of a terminal for first information transmitted via at least a part of first beams; a processing unit configured to determine a preferred beam from a plurality of second beams according to measurement results of the first information transmitted via more than two first beams; and a transmitting unit configured to transmit information about the preferred beam.

Abstract: The present disclosure provides a terminal and a base station. The terminal includes: a receiving unit configured to receive first information transmitted via a plurality of first beams; and a transmitting unit configured to transmit measurement results of the first information transmitted via at least a part of the first beams. The receiving unit is further configured to receive second information transmitted via a preferred beam of a plurality of second beams. The preferred beam is determined by a base station from the plurality of second beams according to measurement results of the first information transmitted via more than two first beams.

Abstract: The present disclosure relates to a communication system based on a neural network model, and a configuration method therefor. The communication system includes at least one master node and multiple child nodes that are in communication connection with the master node, and a child node neural network model is configured in each of the multiple child nodes. The configuration method for the communication system includes: obtaining feature information of the multiple child nodes; and dynamically configuring the child node neural network models on the basis of the obtained feature information.

Abstract: A user apparatus includes: a receiver configured to perform predetermined measurement for a resource set in direct communication between terminals, the resource set having a likelihood of being used by another group to which the user apparatus does not belong; a control unit configured to determine, based on a result of the predetermined measurement, whether an effect from said another group having a likelihood of using the resource set is acceptable; and a transmitter configured to use the resource set to perform transmission to another user apparatus when a determination is made that the effect from said another group that uses the resource set is acceptable.

Abstract: A user device includes a transmission unit that transmits a first traffic to a second user device using a resource scheduled for sidelink by a base station device or a first user device, a reception unit that receives from the base station device or the first user device a sidelink pre-emption indication indicating that all or part of the resource scheduled for the sidelink is to be used for a second traffic, and a control unit that excludes a resource used for the second traffic from the resource for the sidelink used for transmitting the first traffic, based on the sidelink pre-emption indication.

Abstract: A user equipment includes a receiving unit that executes sensing for a part of candidate resources to be used for transmission of inter-terminal direct communication, a control unit that determines a resource to be used for transmission based on a result of the sensing, and a transmitting unit that transmits a message to another units of user equipment using the determined resource.

Abstract: A user apparatus has a request unit configured to transmit a scheduling request to a base station apparatus, an acquisition unit configured to receive information indicative of a resource pool based on the scheduling request from the base station apparatus, and a communication unit configured to perform sidelink transmission to another user apparatus using the resource pool.

Abstract: A user equipment includes a measuring unit that executes sensing of a resource set with which signals from one or more other units of user equipment are transmitted; a control unit that determines, based on a measurement result of the resource set by the sensing, whether to operate as a first device that allocates a resource in the resource set associated with a cluster or to operate as a second device to which a resource is allocated by the first device in the cluster formed of a plurality of units of user equipment; and a communication unit that executes communication with the one or more other units of user equipment.

Abstract: A communication device includes a transmitter that transmits data; and a controller that generates, in response to a predetermined trigger, a request signal including information on a time and frequency location of a radio resource to be used by the transmitter.

Abstract: Disclosed is a user apparatus for use in a radio communication system that supports a D2D communication. The user apparatus includes a setting information storage unit configured to store a plurality of precoding matrices; and a signal transmission unit configured to precode a D2D signal and transmit the precoded D2D signal while switching a precoding matrix among the plurality of precoding matrices in a time domain, in a predetermined time interval including a plurality of unit time intervals. The signal transmission unit maps a reference signal precoded by a same precoding matrix to at least two unit time intervals in the predetermined time interval.
