Abstract: A user equipment includes a receiver and a transmitter and is configured to report channel state information (CSI) to a base station in a communication system in which a plurality of downlink component carriers and at least one uplink component carrier are configured. The receiver receives, in a slot nTrigger, a trigger message that triggers reporting of the CSI for at least one unlicensed downlink component carrier of the plurality of downlink component carriers. The transmitter transmits, in a slot nReport, the CSI based on reference signals present in a slot nRS on the at least one unlicensed downlink component carrier. Responsive to the at least one unlicensed downlink component carrier being occupied for a period of time for a bursty downlink transmission, only the reference signals in the slot nRS are evaluated for the CSI, and other slots in the period of time are not evaluated for the CSI.

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: Provided are a user equipment (UE), an eNode B (eNB) and a wireless communication method for Licensed-Assisted Access (LAA). A UE for LAA according to one embodiment can comprise: a first circuit operative to perform a first listen-before-talk (LBT) in a system bandwidth; a second circuit operative to perform a second LBT in an allocated bandwidth; and a transmitter operative to transmit a signal in the allocated bandwidth if the first LBT is unsuccessful and the second LBT is successful.

Abstract: The present invention relates to a terminal device adapted to perform Licensed Assisted Access, LAA, synchronization and cell discovery, and data reception and transmission on a licensed carrier and on an unlicensed carrier. The terminal device comprises a reception unit adapted to receive, on the licensed carrier, control information message. The control information message includes synchronization and discovery signal information indicating the position of a synchronization and discovery signal on the unlicensed carrier. The reception unit of the terminal device can receive, on the unlicensed carrier at the position indicated by the synchronization and discovery signal information, the synchronization and discovery signal. A timing unit adjusts the timing for transmission and reception of data according to the received synchronization and discovery signal.

Abstract: The invention relates to a method for blind decoding control signal candidates, preconfigured by a base station for a user equipment in a control region of each subframe. A plurality of starting positions is preconfigured between two subsequent subframe boundaries. The subframe is either a partial subframe or a full subframe. A first set of control signal candidates is preconfigured for the UE for the first starting position, and further sets of control signal candidates are preconfigured for the remaining starting positions. The number of control signal candidates of at least one of the further sets is less than the number of control signal candidates of the first set. For each subframe, the UE, for at least the first starting position out of the plurality of starting positions, blind decodes the set of control signal candidates preconfigured for that starting position to receive the one or more control signals.

Abstract: Provided are a resource scheduling method, a resource determining method, an eNB, and a user equipment. The resource scheduling method for wireless communication is performed by the eNB. The wireless communication involves at least a first carrier and a second carrier. The resource scheduling method includes: transmitting a DCI in the first carrier to a UE to schedule downlink resources for a PDSCH of the second carrier, wherein the eNB is able to start transmitting a burst in the second carrier at a flexible time independent of the subframe boundaries of the second carrier after the second carrier is occupied by the eNB, and the DCI for a flexible PDSCH of the burst different from the normal PDSCH of the second carrier contains information on the time period scheduled for the flexible PDSCH. The flexible PDSCH and its corresponding RS can reuse the DwPTS subframe structure for minimal specification impact.

Abstract: The invention relates to a method for allocating radio resources to a user terminal for performing communication between a radio control entity and the user terminal in a communication system. At least first predetermined radio resources are configured in the user terminal for use in connection with a particular carrier and are associated with a particular format of a downlink control information, DCI, message. The user terminal receives a DCI message of the particular format from the radio control entity. Upon receiving the DCI message of the particular format, the user terminal identifies the first predetermined radio resources associated with this received DCI message, and using the identified first predetermined radio resources for communication between the user terminal and the radio control entity via the particular carrier. The particular carrier can be an unlicensed carrier.

Abstract: The present invention relates to transmitting data on a shared communication channel in a communication system supporting multiple hybrid automatic repeat request processes and configurable to apply a bundling of transmission time intervals. The data transmitting including mapping of TTIs of the HARQ processes cyclically onto subframes. In order to efficiently support dynamic bundle scheduling, when a grant is received during a bundle transmission, this grant becomes a shifting grant, according to which the bundle is transmitted and according to the location of which the timing of the grant reception and the data transmission is adapted. The transmission of the shifted bundle is performed in accordance with the state of its retransmission process, i.e. the bundle is either initially transmitted or retransmitted.
