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 present invention relates to transmission and reception of downlink control information in a communication system. In particular, a serving base station transmits to a terminal a downlink control information which includes a first field with a scheduling information and a second field with interference parameters (interference information). The receiver employs the interference parameters for interference estimation used in interference cancellation or suppression.

Abstract: The present disclosure provides a band usage information generating and reporting method, a charging method, an eNB, a CN, a MME and a UE. The eNB and the UE can generate band usage information for charging, and report the band usage information to the CN, wherein the band usage information involves band usage of at least a first band and a second band, and traffic is assigned to respective bands by the eNB. The Counting entity at the eNB or UE can count the data volume of each band or ratio of data volume via different bands as the band usage information based on the scheduling information of the data. The Charging system located in the CN can process the charging and generate a bill according to the reported band usage information.

Abstract: Provided are a user equipment and a wireless communication method for LAA. The user equipment comprises: a receiver operative to receive a UL grant which schedules a subframe for UL transmission; a first circuit operative to perform LBT; a transmitter operative to transmit a PUSCH in the scheduled subframe starting from one available starting position of multiple candidate starting positions in the scheduled subframe if the LBT is successful. According to present disclosure, it is possible to increase the possibility that PUSCH could be sent in the scheduled subframe after LBT.

Abstract: Provided are wireless communication methods, a UE and an eNB. The wireless communication method performed by a UE includes transmitting transport block repetitions to an eNB, wherein one HARQ process includes multiple repetition sets of a transport block if one repetition set of the transport block is not enough for the eNB to successfully decode the transport block, each of the multiple repetition sets includes multiple repetitions of the transport block, each of the multiple repetition sets is followed by a feedback channel to indicate whether the transport block is successfully decoded by the eNB.

Abstract: The present disclosure provides a wireless communication method and an eNode B and user equipment therefor. The wireless communication method performed by the eNB comprises steps of transmitting a first downlink control information (DCI) to a UE in a first physical downlink control channel (PDCCH) candidate or enhanced PDCCH (EPDCCH) candidate; and transmitting a second DCI to the UE in a second PDCCH candidate or EPDCCH candidate, wherein the assignment of the second PDCCH candidate or EPDCCH candidate is determined based on the assignment of the first PDCCH candidate or EPDCCH candidate according to a predefined algorithm configured through radio resource control (RRC) signaling or fixed by specification. According the present disclosure, the BD trials for DCIs can be reduced.
