摘要： A user equipment, apparatus provided in a user equipment, and method are for receiving a Multicast Broadcast Service, and include receiving a system information block (SIB) from a current serving cell of the user equipment, and performing a cell reselection operation where a cell having a highest ranking determined based on a radio quality and an offset is selected as a serving cell of the user equipment from among a plurality of cells. In the cell reselection operation, a determination is made, based on the SIB, whether to use an infinite offset as the offset to be applied to a cell providing the Multicast Broadcast Service.

摘要： A user equipment supports MBMS (Multimedia Broadcast Multicast Service) transmission using SC-PTM (Single Cell Point-To-Multipoint). The user equipment receives an MBMS service from a base station via SC-MTCH (Single Cell Multicast Traffic Channel). The user equipment receives, from the base station, MAC (Medium Access Control) CE (Control Element) indicating a suspension of transmission of the MBMS service via the SC-MTCH. The user equipment determines that the transmission of the MBMS service via the SC-MTCH is suspended in response to the reception of the MAC CE.

摘要： A communication method according to an embodiment comprises: notifying, by a base station, a radio terminal of a discontinuous reception (DRX) cycle; notifying, by a Mobility Management Entity (MME), the radio terminal of an extended DRX cycle longer than the DRX cycle; determining, by the radio terminal, whether or not the base station supports an extend DRX; using, by the radio terminal, the extended DRX cycle to execute an extended DRX operation in an idle mode, in response to determining that the base station supports the extend DRX; and using, by the radio terminal, the DRX cycle to execute a DRX operation without using the extended DRX cycle, in response to determining that the base station does not support the extend DRX.

摘要： A relay radio terminal according to a first aspect performs a process for relaying communication between a base station and a remote radio terminal in a mobile communication system. In a state in which the relay radio terminal is in an idle mode and an end-to-end radio link between the relay radio terminal and the remote radio terminal is established, the controller is configured to perform a process of receiving, from the base station, a paging message including an identifier of the remote radio terminal as a call destination in a paging reception opportunity of the relay radio terminal, and a process of determining whether not only the remote radio terminal but also the relay radio terminal is called, in response to reception of the paging message.

摘要： A base station according to a present embodiment is a base station configured to manage a cell, and comprises: a controller configured to transmit, if a relay terminal configured to relay data by direct communication between a remote terminal and a network is not present in a vicinity of a radio terminal located within the cell, control information to the radio terminal. The control information is information for starting transmission of a discovery signal for discovering another radio terminal that can be the relay UE.

摘要： In a communication control method according to a present embodiment, at least one radio terminal of a first radio terminal and a second radio terminal discoveries the other radio terminal by executing a discovery for discovering a proximal terminal. The at least one radio terminal reports, to a network apparatus that the other radio terminal is discovered. The network apparatus requests, while the first radio terminal is located within a coverage of a cell, at least one of the first radio terminal and the second radio terminal to make a preparation for executing a relay by the second radio terminal by utilizing a proximal service.

摘要： A radio terminal according to one embodiment is used in a mobile communication system. The radio terminal comprises a controller configured to perform control related to a DRX operation for intermittently monitoring a downlink control channel based on a comparison result of a value related to a moving speed of the radio terminal and a threshold value when the extended DRX operation is set from a network.
