    摘要: The present disclosure relates to a user equipment (UE), comprising the following. A receiver of the UE receives, from a present base station, a delta common configuration indication, indicating a difference between a present common configuration and a target common configuration. The present common configuration is used by the UE for communication with a present base station that controls a present radio cell in which the UE is located. The target common configuration is usable by the UE for communication with a target base station. The receiver receives, from the present base station, differing common configuration elements of the target common configuration, based on the received delta common configuration indication. The differing common configuration elements are different between the present common configuration and the target common configuration. The receiver receives, from the present base station, a target individual configuration to be used for communication with the target base station.

    摘要: The present disclosure relates to a user equipment (UE) that comprises a receiver of the UE receives, from a source base station of a source radio cell, a common timing advance value for a target radio cell. The UE is connected to the source radio cell and is involved in a handover procedure to hand over the UE from the source radio cell to the target radio cell. Further, the common timing advance value is received from the source base station in a first message of the handover procedure, which also comprises a timing indication for transmitting a second message from the UE to the target base station. Then, a processor of the UE determines a first uplink timing of uplink transmissions to the target base station with respect to downlink transmissions from the target base station, based on the received common timing advance value and the timing indication. A transmitter of the UE transmits a second message of the handover procedure to the target base station based on the determined uplink timing. The processor determines a UE-specific timing advance value, specific to the UE and the target radio cell, to be used by the UE for performing uplink transmissions in the target radio cell.

    摘要: The present disclosure provides a transceiver device and a base station, and communication methods for a transceiver devices and a base station. The transceiver device comprises a transceiver, which in operation, receives a timing pattern indicator indicating a timing pattern including a first duration of a first period and a second duration of a second period; and circuitry, which in operation, sets first periods of the first duration and second periods of the second duration in an alternating manner according to the timing pattern, wherein the transceiver, in operation, performs communication with a first base station during the first periods, and performs communication with a second base station according to a random-access procedure during the second periods.

    摘要: The present disclosure relates to a user equipment (UE) that comprises a receiver, which receives, from abase station, a minimum cross-slot time-domain scheduling parameter, indicating a minimum amount of slots between a scheduling downlink control information, DCI, and an uplink or downlink transmission scheduled by the scheduling DCI. The minimum cross-slot time domain scheduling parameter is carried by a DCI message. Processing circuitry of the UE determines an updating time at which a previously-received minimum cross-slot time-domain scheduling parameter is to be updated based on the received minimum cross-slot time-domain scheduling parameter and then updates the previously-received minimum cross-slot time-domain scheduling parameter based on the received minimum cross-slot time-domain scheduling parameter at the determined updating time. The updating time is determined based on a message exchanged between the UE and the base station, wherein the message relates to the DCI message carrying the minimum cross-slot time-domain scheduling parameter.

    摘要: The present disclosure relates to a user equipment comprising a receiver receiving a minimum-system-information message from a first radio base station. System information for the first radio cell that can be acquired by the UE is carried within the minimum-SI message and one or more additional-SI messages. The minimum-SI message includes system information for accessing the first radio cell and at least one system information index, each of which is associated with one of the additional-SI messages. The SI message index comprises a value tag and an area pointer, the latter pointing to one area already defined. Processing circuitry determines whether the UE had already acquired before the additional-SI message associated with the same value tag and the same area. If the determination is positive, the processing circuitry determines that system information included in said additional-SI message acquired before is applicable to the first radio cell.

    摘要: The present disclosure relates to a user equipment (UE) comprises a receiver, which receives reference signals from a serving base station on which the UE is camping, the serving base station controlling an unlicensed serving radio cell in which the UE is located. Processing circuitry of the UE monitors the reception of reference signals to determine a number of reference signals that are continuously missing. The processing circuitry determines to perform cell re-selection from the unlicensed serving radio cell on which the UE is camping to another radio cell that has a different frequency than the unlicensed serving radio cell, in case the determined number of reference signals that are continuously missing is above a threshold.
