Abstract: A radio measurement collection method is a method performed by a user equipment in a mobile communication system in which, in addition to a normal coverage, different enhanced coverages are formed for respective coverage enhancement levels. The radio measurement collection method includes storing, based on an enhanced coverage of the different enhanced coverages in which the user equipment is located, a measurement log including measurement information regarding a radio environment for the user equipment and position information regarding the user equipment, and transmitting, to a network, the measurement log stored.

Abstract: A user equipment, method used in a user equipment, and apparatus controlling a user equipment receive an RRC (Radio Resource Control) Release message when the user equipment is in an RRC connected state. The RRC Release message includes information indicating an uplink radio resource used for transmitting uplink data from the user equipment in an RRC inactive state. The user equipment, method, and apparatus control, in response to receiving the RRC Release message, the user equipment to transition from the RRC connected state to the RRC inactive state. The user equipment, method, and apparatus transmit the uplink data by using the uplink radio resource indicated by the information included in the RRC Release message when the user equipment is in the RRC inactive state.

Abstract: A user equipment, apparatus, and method receives from a base station, a message for transitioning a user equipment from a Radio Resource Control (RRC) connected state to a RRC inactive state, starts a timer included in the message, transitioning to a RRC idle state from the RRC inactive state after the timer expires, discards a cell reselection priority included in the message in response to transitioning to the RRC idle state, and applies another cell reselection priority acquired from a serving cell.

Abstract: A base station allocates unmanned aerial vehicles (UAVs) preambles for use by UAV user equipment (UE) devices that are different from terrestrial preambles allocated for terrestrial UE devices. The UAV preambles can be allocated to different subscription levels, such that each UAV UE device can only use UAV preambles associated with the UAV UE device's subscription level. The UAV UE device transmits random access request message using the selected UAV preamble and the base station responds with a random access response message indicating whether access is granted to the UAV UE device. The base station can dynamically manage access to the base station by limiting the subscription levels that are associated with the UAV preambles.

Abstract: In a user equipment, base station and method for a mobile communication system, the user equipment receives, from a first base station, transmission power control information used for a dual simultaneous transmission in which radio signals are simultaneously transmitted to both the first base station and a second base station, and determines a first transmission power and a second transmission power for the dual simultaneous transmission based on the transmission power control information. The first transmission power is used for transmitting a radio signal to the first base station, and the second transmission power is used for transmitting a radio signal to the second base station.

Abstract: 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.

Abstract: A user equipment, apparatus, and method transmits a random access preamble to a cell and receives a message including a random access response as a response to the random access preamble from the cell. The message indicates that a Radio Resource Control (RRC) connection to the cell is rejected.

Abstract: A communication control method according to an embodiment is a method for controlling specific data transmission in which a user equipment transmits or receives data of a predetermined size or smaller size during a random access procedure. The communication control method includes transmitting, by the user equipment in an RRC connected state, to a base station, assistance information for the base station to determine whether to perform, on the user equipment, data transmission configuration necessary for performing the specific data transmission, and in response to determining, based on the assistance information, to perform the data transmission configuration on the user equipment, transmitting, by the base station, to the user equipment, an RRC release message including configuration information indicating the data transmission configuration.

Abstract: A mobile communication system comprises gNB 200-1 and IAB node 300-1. The IAB node 300-1 is configured to have a UE function and a gNB function and establish a first radio connection with the gNB 200-1 by using the UE function. The gNB 200-1 is configured to transmit, to the IAB node 300-1, a message for establishing, while maintaining the first radio connection, a second radio connection for the gNB function of the IAB node 300-1 between the IAB node 300-1 and the gNB 200-1.

Abstract: A first user equipment (UE) device receives a configuration for a first timer from a base station that is serving the UE device. The first UE device also receives a recommended bitrate from the base station. The recommended bitrate is to be used for a Voice over Long-Term Evolution (VoLTE) call or a Video over Long-Term Evolution (ViLTE) call between the first UE device and a second UE device. The first UE device activates the first timer in accordance with the configuration. The first UE device is prohibited from transmitting a bitrate query to the base station while the first timer is running. Upon receiving a recommended bitrate that is below a Guaranteed Bit Rate for the call between the first UE device and the second UE device, the first UE device stops the first timer and transmits a bitrate query to the base station.
