Abstract: A handover control method for performing a conditional handover of a user equipment from a source cell to a target cell, the source cell to which the user equipment connects. The handover control method comprises transmitting, by a source base station which manages the source cell to the user equipment, a RRC message including a list of candidate cells which are candidates for the target cell and a handover condition specified for each of the candidate cells in the list; and starting, by the source base station, transfer of a copy of downlink data of the user equipment to a candidate base station which manages the candidate cell in the list before the user equipment performs the handover.

Abstract: The communication control method includes making, by a first communication node including a relay node under the first communication node, an inquiry about cell IDs available in the relay node to a second communication node. The communication control method includes, in response to the inquiry, by the second communication node, determining a cell ID not colliding with the cell ID available in the second communication node from among the cell IDs available in the relay node, and transmitting the determined cell ID to the first communication node. The communication control method includes transmitting, by the first communication node, the determined cell ID to the relay node. The communication control method includes executing, by the relay node, movement processing by using the determined cell ID.

Abstract: A relay user equipment (UE) device transmits a Radio Resource Control (RRC) connection status indicator indicating the RRC connection status of the relay UE device to a serving base station. The RRC connection status indicator may be used by a remote UE device to manage relay communication to the base station. In one example, a remote UE device in direct communication with the base station transmits a measurement report to the base station where the measurement report includes measurements only for relay UE devices reporting a RRC connected (RRC CONN) status. The base station manages direct to indirect communication switching at least partially based on the measurement report. In another example, a remote UE device manages relay reselection using a relay candidate prioritization at least partially based on the connection status of candidate relay UE devices.

Abstract: A communication control method used in a mobile communication system includes receiving, at a base station shared by a plurality of core networks from each of the plurality of core networks, an MBS service identifier indicating an MBS service provided by the corresponding one of the plurality of core networks; and transmitting, at the base station, MBS data belonging to the MBS service to a plurality of user equipments belonging to a plurality of Public Land Mobile Networks (PLMNs) corresponding to the plurality of core networks through multicast or broadcast. The MBS service identifier is a unique identifier independent of the plurality of PLMNs.

Abstract: In a first aspect, a communication control method is used in a cellular communication system. The communication control method includes performing, by a donor node for each of a first user equipment and a second user equipment, configuration to establish a data radio bearer (DRB) between the first user equipment and the second user equipment. The communication control method includes establishing, by the first user equipment and the second user equipment, a first Packet Data Convergence Protocol (PDCP) entity and a second PDCP entity, respectively, in response to receiving the configuration. The communication control method includes transmitting, by the first PDCP entity, data to the second PDCP entity without involving a User Plane Function (UPF).

Abstract: The devices, systems, and methods discussed herein involve abase station (e.g., gNB) that employs a broadcast technology such as the Multimedia Broadcast Multicast Service (MBMS) to relay hidden-node information to the neighboring UE devices. In some examples, a base station receives at least one report based on data acquired by at least one non-communication sensor of a user equipment (UE) device. Based on the at least one report, the base station transmits a message to another UE device that results in the other UE device refraining from using communication resources that will interfere with transmissions by other UE devices.
