Abstract: An integrated circuit includes reception circuitry and demodulation circuitry. The reception circuitry, in operation, controls receiving one or more repetitions of control information in a search space region. The search space region includes a first plurality of sub-regions of different lengths for a largest repetition number of the control information. The search space region includes a second plurality of sub-regions of different lengths for a second-largest repetition number of the control information. An interval of subframes to which the first plurality of sub-regions are mapped is greater than an interval of subframes to which the second plurality of sub-regions are mapped. The demodulation circuitry, in operation, controls performing a demodulation process of the one or more repetitions of the control information.

Abstract: A communication apparatus includes circuitry which, in operation, maps one or more repetitions of control information in a search space region, and a transmitter which, in operation, transmits the one or more repetitions of the control information. The search space region includes a first plurality of sub-regions of different lengths for a largest repetition number of the control information, and a second plurality of sub-regions of different lengths for a second-largest repetition number of the control information. An interval of subframes to which the first plurality of sub-regions are mapped is greater than an interval of subframes to which the second plurality of sub-regions are mapped.

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 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: Provided are wireless communication methods, an eNB and a UE. A wireless communication method performed by the eNB includes transmitting repetitions of control channel(s) in a control region to a first UE in a coverage enhancement level, wherein the control region includes multiple sub-regions each of which can be used to transmit repetitions of one control channel; possible sub-region(s) allocated from the multiple sub-regions for transmitting one control channel to the first UE in the coverage enhancement level start from the same subframe; and the possible sub-region(s) for the first UE in the specific coverage enhancement level constitute a subset of a set of available sub-regions for the coverage enhancement level in the eNB's perspective.

Abstract: The present disclosure provides wireless communication methods for repeated transmission of channels, and wireless communication devices therefor. In one embodiment, the gap between the starting subframe of a first channel and the starting subframe of a second channel is defined or configured. In another embodiment, Mx*W=M and Mx*n=N is satisfied, where Mx is the number of subframes reserved for the channel in one HARQ process, M is RTT for one HARQ process, W is a positive integer and represents the maximum number of HARQ processes transmitting the channel within M subframes, N is the gap between the starting subframes of the channel in two HARQ processes, and n is a positive integer. In yet another embodiment, time-frequency resources for the channel in different HARQ processes are different.
