    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： 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.
