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: In a base station, a signal allocating unit allocates downlink control signals (DCI) to a control channel region (CORESET) constituted by a plurality of control channel elements (CCEs), and a transmitting unit transmits the downlink control signals. In this case, the number of resource element groups (REGs) that constitute the CCE is a power of 2, and a bundling size indicating the number of REGs included in the REGs that constitute the CCE and arranged in adjacent resource blocks is a power of 2.

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 a base station, user equipment and wireless communication methods related to DCI design for blind detection. A base station comprises: circuitry operative to align, for each DCI of a first group of DCIs, one of the size of the DCI of the first group and the size of a selected DCI of a second group of DCIs with the other, if the size of the DCI of the first group is different from the size of each DCI of the second group of DCIs, wherein the selected DCI of the second group is a DCI whose size is closest to the size of the DCI of the first group among DCIs of the second group having sizes larger than the size of the DCI of the first group or a DCI whose size is closest to the size of the DCI of the first group among DCIs of the second group having sizes smaller than the size of the DCI of the first group; and a transmitter operative to transmit the first group of DCIs and the second group of DCIs after the size alignment by the circuitry to a user equipment, wherein the size alignment is based on a rule which is known by the base station and the user equipment beforehand.

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: In a base station, control circuitry determines, based on an offset for defining a frequency position of a narrowband allocated to an MPDCCH and a resource block group size of a system band, allocations of a first EPDCCH set and a second EPDCCH set that constitute the MPDCCH. The MPDCCH is a PDCCH for MTC. The second EPDCCH set has a different number of PRBs from the first EPDCCH set. A transmitter transmits a control signal according to the allocations of the first EPDCCH set and the second EPDCCH set. Further, the control circuitry controls a number of RBGs in which both the first EPDCCH set and the second EPDCCH set are allocated to be zero or one.

Abstract: A resource assignment determiner determines a resource for a PDSCH intended for an MTC terminal, and a transmitter transmits an MPDCCH that includes resource assignment bits indicating the resource thus determined and transmits the PDSCH using the resource thus determined. The MPDCCH is a PDCCH intended for the MTC terminal. The resource assignment bits are associated with a resource that is used when the MPDCCH and the PDSCH are transmitted in the same subframe and a resource that is used when the MPDCCH and the PDSCH are transmitted in different subframes.

Abstract: In a base station, a first setting circuitry sets a first Narrowband for allocating a system information block (SIB) for MTC by using a predetermined default offset. A second setting circuitry sets a second Narrowband for allocating a signal other than the SIB by using the default offset and an additional offset that indicates a difference from the default offset. An allocating circuitry allocates the SIB including the additional offset to the first Narrowband, and allocates the signal other than the SIB to the second Narrowband.
