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: 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 user equipment, with a processor which upon being triggered by a random access events, determines random access transmission parameters to be used by the UE for transmitting a random access message to its base station. At least part of the random access transmission parameters are determined based on the random access event that triggered the transmission of the random access message and on random access configuration information. The random access configuration information associates each of a plurality of random access events with a set of random access transmission parameters among a plurality of random access transmission parameters usable by the user equipment to transmit a random access message to the base station. A transmitter of the UE transmits the random access message to the base station using the determined random access transmission parameters.

Abstract: The present disclosure relates to a mobile terminal, a base station, an operating method for a mobile terminal and an operating method for a base station. The mobile terminal is for communicating in a mobile communication system with a base station using at least one of a plurality of downlink beams and at least one of a plurality of uplink beams, each of the downlink and uplink beams having different directivities and/or coverage, comprising: which, in operation, receives for a beam failure recovery, BFR, procedure an allocation of dedicated uplink radio resources for transmitting a beam failure recovery signal, a processor which, in operation, detects a downlink beam failure event and, in response thereto, initiates the beam failure recovery procedure, including the transceiver transmitting the beam failure recovery signal using the dedicated uplink radio resources from the allocation; wherein the dedicated uplink radio resources are restricting the transmission to a subset of the plurality of uplink beams that can be exclusively allocated by the base station to the mobile terminal.
