Abstract: The present disclosure relates to a mobile terminal for performing a handover procedure in a mobile communication system from a source to a target base station. The target base station is configured for the mobile terminal with at least a first and a different second bandwidth part within its cell bandwidth. The mobile terminal comprises: a transceiver which, in operation, receives from the source base station a handover command message including information regarding the configured at least first and second bandwidth part; and a processor which, in operation and upon reception of the handover command message, activates in the transceiver at least a selected one of the configured at least first or second bandwidth part, and controls the transceiver to perform, over the activated at least one of the configured at least first or second bandwidth part, communication with the target base station as part of the handover procedure.

Abstract: The present disclosure relates to a source base station. The source base station comprises a processing circuitry that generates a user equipment packet duplication status. The user equipment packet duplication status includes information on the status of uplink packet duplication performed by a user equipment with the source base station and at least one further base station. The information on the status of uplink packet duplication is per uplink radio bearer, one or more uplink radio bearers being established between the user equipment and the source base station. The source base station further comprises a transmitter that transmits the user equipment packet duplication status to a target base station which is the target of a handover from the source base station performed for the user equipment.

Abstract: The present disclosure relates to a mobile terminal, a base station and respective operation methods. The mobile terminal comprises circuitry, which in operation assumes that a base station is configured to use one of a plurality of transmission beams, receives a downlink control channel candidate and a corresponding demodulation reference signal using one of a plurality of reception beams corresponding to the assumed one of the plurality of transmission beams, performs channel estimation based on the received demodulation reference signal, and, depending on the quality, demodulates the downlink control channel candidate using the channel estimation. The channel estimation is performed using a demodulation reference signal sequence which is generated observing an association which is associating the generated sequence with the assumed one of the plurality of transmission beams such that at least two of the plurality of transmission beams are associated with different demodulation reference signal sequences.

Abstract: Provided are a user equipment (UE), a scheduling node, and communication methods for a UE and a scheduling node. The UE comprises a transceiver which, in operation, performs listen before talk, LBT and circuitry which, in operation, performs at least one of: incrementing a counter upon determining LBT failure, starting a triggering timer upon determining LBT failure if the triggering timer is not running, and determining whether the counter has reached a threshold value upon expiry of the triggering timer; and incrementing the counter upon determining a number N of consecutive LBT failures due to ongoing LBT backoff. The circuitry generates a indicating consistent LBT failure upon determining that the counter has reached the threshold value, and the transceiver, in operation, declares consistent LBT failure.

Abstract: The present disclosure relates to a mobile terminal and base station and respective operation methods. The mobile terminal comprises circuitry, which in operation, determines a condition for requesting on-demand a transmission of other system information; performs a random access procedure; and receives via broadcast a system information message including the on-demand requested other system information. The system information request message of the random access procedure includes an information element with a bit-pattern conforming to a specific format with at least a part of the bit-pattern for requesting the other system information. And the contention resolution message of the random access procedure includes the same, or the same part of the bit-pattern for detecting collisions during the random access procedure.

Abstract: The present disclosure relates to a user equipment (UE) which comprises a transmitter that transmits at least one data packet based on a transmitting window having a transmitting window size. A receiver of the UE receives reception feedback regarding the at least one transmitted data packet. Processing circuitry of the UE determines, based on at least the received reception feedback, whether to change the transmitting window size for the transmitting window to be used at least for transmitting further data packets.

Abstract: The present disclosure relates to a user equipment (UE) which receives, from a base station via an unlicensed radio cell, uplink configuration information to configure at least one set of radio resources of the unlicensed radio cell available for transmitting uplink control information, the radio resource set being associated with a UE group ID indicating a UE group to which the UE is associated. The UE receives, from the base station, downlink control information, DCI, indicating a UE group ID. The UE, when determining that the associated UE group ID is the same as the UE group ID indicated by the DCI, determines scheduling request radio resources within the at least one set of uplink control information radio resources based on the received downlink control information. The UE transmits a scheduling request to the base station using the determined scheduling request radio resources.

Abstract: The present disclosure provides a transceiver device and a scheduling device, and communication methods for transceiver device and scheduling device. The transceiver device comprises a transceiver, which, in operation, transmits a scheduling request for scheduling data over a physical uplink control channel, PUCCH; and circuitry, which, in operation, initiates a monitoring sleeping timer after the transceiver transmitted the scheduling request, wherein the transceiver, in operation, does not monitor a physical downlink control channel, PDCCH, while the monitoring sleeping timer is running, and starts monitoring the PDCCH for resource allocation for the scheduling data when the monitoring sleeping timer has expired.
