Abstract: A communication method is to be performed by a user equipment in a mobile communication system providing multicast broadcast services (MBS). The communication method includes: receiving a predetermined system information block (SIB) that may include frequency information indicating a correspondence relationship between an identifier of an MBS service and a frequency for providing the MBS service from a serving cell; generating an MBS interest indication including a list indicating a frequency of interest being an MBS frequency that a user equipment is receiving or is interested in receiving; and transmitting the MBS interest indication to the serving cell. The user equipment includes the frequency of interest in the list when the frequency of interest is indicated in upper layer information, even when the frequency of interest is not included in the predetermined SIB.

Abstract: In an aspect, a communication control method is a communication control method in a mobile communication system configured to perform a first communication on a direct link between a remote user equipment and a base station and a second communication on an indirect link between the remote user equipment and the base station via a relay user equipment. The communication control method includes transmitting, by the base station, to the remote user equipment, association information associating a PDCP entity with an RLC entity for the direct link and an SRAP entity for the indirect link. The communication control method includes associating, by the remote user equipment, the PDCP entity with the RLC entity and the SRAP entity in accordance with the association information.

Abstract: User equipment, a system and a method perform a predetermined data transmission in which the user equipment transmits uplink user data when the user equipment is in a radio resource control (RRC) inactive state. The user equipment, apparatus and method receive from a network node, a first timer value for a RRC connection resume procedure without the predetermined data transmission and a second timer value for a RRC connection resume procedure with the predetermined data transmission, transmit to the network node during a random access procedure, a random access preamble, start a timer configured with the second timer value in response to transmitting a RRC resume message together with the uplink user data, and in response to the timer being expired, determine that the predetermined data transmission is failed.

Abstract: A communication control method includes: configuring, for a relay node, dual connectivity in which a first parent node managing a master cell group is a master node and a second parent node managing a secondary cell group is a secondary node; transmitting, by the relay node, a first notification to a child node when a radio link failure is detected in one of a first backhaul link between the relay node and the first parent node and a second backhaul link between the relay node and the second parent node, the first notification indicating detection of the radio link failure; and transmitting, by the relay node, a second notification to the child node when recovery from the radio link failure occurs after transmitting the first notification, the second notification being transmitted after transmitting the first notification and indicating recovery from the radio link failure.

Abstract: The methods and systems discussed herein describe how a first wireless communication device forwards a reservation signal, which identifies one or more time-slots that have been reserved by a second wireless communication device, to avoid “merging collisions.” In some examples, the first wireless communication device determines that it should forward the reservation signal based on a determination that the first wireless communication device is located at the edge of a coverage area associated with the second wireless communication device. This determination can be based on location information associated with the second wireless communication device or whether a received power value of the reservation signal is within a pre-defined threshold range value. In other examples, the first wireless communication device transmits an updated forwarded reservation signal, which is an update of a previously forwarded reservation signal in which multiple time-slots were reserved.

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: 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 user equipment comprises transceiver circuitry and processing circuitry operatively associated with the transceiver circuitry. The transceiver circuitry is configured to execute processes of receiving, from a network, a Radio Resource Control (RRC) message including an instruction to transition to a specific state where an RRC connection of the user equipment is suspended, the RRC message including information indicating a radio resource for uplink transmission; and performing the uplink transmission using the radio resource when the user equipment is in the specific state. A method for a user equipment comprises receiving, from a network, a Radio Resource Control (RRC) message including an instruction to transition to a specific state where an RRC connection of the user equipment is suspended, the RRC message including information indicating a radio resource for uplink transmission; and performing the uplink transmission using the radio resource when the user equipment is in the specific state.

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.

Abstract: A communication control method according to a first aspect is performed by a user equipment in a mobile communication system for providing a multicast service to the user equipment, the communication control method including monitoring a paging message transmitted from a base station. The monitoring includes: monitoring, when an early paging notification signal is received from the base station, a first paging message that calls one or more user equipments being targets of unicast communication; and monitoring, when the user equipment has joined or is interested in a multicast session, a second paging message that notifies that one or more multicast sessions have been activated even when the early paging notification signal has not been received.
