Abstract: An invention relates to methods for transmitting a buffer status report (BSR) in a mobile communication system, more particularly to the definition of rules for triggering, generating and transmitting BSRs. The invention also relates to a data transmission method utilizing new rules to decide data of which radio bearers is transmitted within a given transmission time interval. Moreover, the invention relates to scheduling method for radio resources that is taking into account additional scheduling-relevant information from the buffer status reporting and/or data transmission method. To avoid unnecessary grants from the network and to suggest an advanced handling of data transmissions the invention suggests a buffer status reporting and data transmission schemes that take into account the scheduling mode of data of radio bearers pending for transmission to decide whether to report on it in a buffer status report, respectively, whether to multiplex the data to a transport block for transmission.

Abstract: The present disclosure relates to a method for operating a Discontinuous Reception, DRX, function at a user equipment. The UE is configured with at least one licensed cell and at least one unlicensed cell and operates the DRX function. The UE receives, from a radio base station, a DRX-active instruction to be in DRX Active Time at least on the unlicensed cell until receiving the next downlink control information related to a downlink data transmission to be received via the unlicensed cell. Correspondingly, in response to the received DRX-active instruction, the UE is in DRX Active Time at least on the unlicensed cell, comprising continuously monitoring a downlink control channel for downlink control information.

Abstract: A user equipment includes circuitry which selects a random access preamble sequence, and a transmitter which transmits the random access preamble sequence to a base station in a frequency bandwidth of an unlicensed band, and performs at least one of a first operation and a second operation. In the first operation, the circuitry selects a first sequence as the random access preamble sequence, the first sequence having a length longer than a length of a random preamble sequence used for a licensed band, and the transmitter transmits the first sequence in the frequency bandwidth of the unlicensed band. In the second operation, the circuitry selects a second sequence as the random access preamble sequence, the second sequence having a length equal to the length of a random preamble sequence used for the licensed band, and the transmitter transmits the second sequence with repetitions in the frequency bandwidth of the unlicensed band.

Abstract: The invention relates to an improved semi-persistent resource allocation for a mobile terminal (MT) for transmitting periodic data. The MT transmits information on the periodic data to the radio base station (BS), such that the BS determines the different possible transmission periodicities and/or the different possible message sizes of the data components of the periodic data. The MT receives from the BS plural semi-persistent resource (SPS) configurations, each being usable to transmit at least one of the supported data components. The MT indicates to the BS the data components that are to be transmitted by the MT. The MT receives from the BS an activation command to activate one or more of the SPS configurations to periodically allocate radio resources for the MT to transmit each of the indicated data components. The MT then transmits the one or more data components based on the radio resources and the transmission periodicity as configured by the activated one or more SPS configurations.

Abstract: The present disclosure relates to a resource allocation procedure, performed between a user equipment and radio base station. The UE is configured with at least one numerology scheme, each associated with parameters partitioning time-frequency radio resources into resource scheduling units differently. The UE is configured with logical channels each of which is associated with at least one numerology scheme. A receiver of the UE receives from the radio base station an uplink scheduling assignment, which indicates uplink radio resources usable by the UE. A processor of the UE determines for which numerology scheme the received uplink scheduling assignment is intended based on the received uplink scheduling assignment. The processor performs a logical channel prioritization procedure by allocating the assigned uplink radio resources to the configured logical channels and by prioritizing those logical channels that are associated with the numerology scheme for which the uplink scheduling assignment is intended.

Abstract: The present disclosure relates to a relay UE for relaying protocol data units between a remote UE and a radio base station. A control packet is received by the relay UE from the remote UE via a first sidelink bearer, comprising a priority indication associated with protocol data units transmitted by the remote user equipment via the first sidelink bearer. The relay UE stores an association between the priority indication and a radio bearer used by the relay UE to relay the protocol data packets. The relay UE determines, based on the stored association, the priority according to which a protocol data unit, received from the base station via the first radio bearer, should be transmitted to the remote UE, and relays the received protocol data unit to the remote user equipment using a second sidelink bearer that corresponds to the determined priority.

Abstract: The invention relates to transmitting and receiving data in subframes of a wireless communication system. It includes at the user equipment receiving an uplink grant for transmitting data on predetermined resources of an uplink carrier; detecting by carrier sensing whether or not the predetermined resources are available for transmission; and if the predetermined resources are detected to be available for transmission, transmitting data in the predetermined resources and transmitting a transmission confirmation indication indicating that the data has been transmitted. At the receiving side, the transmission confirmation indication is transmitted and based on, the received data is handled.

Abstract: The disclosure relates to an improved vehicular UE for transmitting vehicular data and other data to one or more receiving entities. The vehicular UE receives an uplink grant from a radio base station controlling the cell to which the vehicular mobile terminal is attached, wherein the uplink grant indicates radio resources usable by the vehicular mobile terminal to transmit the vehicular data and/or the other data. The vehicular UE transmits the vehicular data and/or the other data using the radio resources indicated in the uplink grant. The vehicular mobile terminal handles the vehicular data and the other data separately from one another.
