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: The present disclosure provides a wireless communication method and an eNode B and user equipment therefor. The method comprises a step of transmitting multiple PDCCH or EPDCCH repetitions respectively in multiple successive downlink subframes with a transmission repetition number and a transmission starting subframe. The transmission starting subframe is selected from a first starting subframe set corresponding to the first repetition number or a second starting subframe set corresponding to the second repetition number. The subframe indexes of any two adjacent starting subframes in the first starting subframe set are offset by a same first index interval, the subframe indexes of any two adjacent starting subframes in the second starting subframe set are offset by a same second index interval, and the second index interval is an integral multiple of the first index interval. According to the present disclosure, the resource blocking probability of different repetition numbers, UE's detection complexity can be decreased, and eNB's scheduling complexity.

Abstract: The present invention relates to transmitting and receiving data in a wireless communication system employing time division duplex, and in particular to a rate matching for the channels which are mapped onto special subframes such as uplink/downlink switching subframes in TDD. Accordingly, at the transmitter, a data block is stored in a memory unit which is to be operated as a circular buffer, the data block is transmitted in a plurality of subframes including special subframes, a special subframe containing an uplink portion and a downlink portion separated from each other by a switching portion; and before the transmission a rate matching is performed by mapping the stored data block onto the plurality of subframes using the circular buffer, wherein the mapping of bits onto two different special subframes starts from different respective positions in the circular buffer. Moreover, a corresponding receiving apparatus and a transmitting and receiving method are provided.
