Abstract: A base station selects, from among a plurality of code sequences orthogonal to one another, one code sequence by which an uplink signal including a demodulation reference signal repeated in a plurality of subframes is multiplied and transmits, to a terminal for which transmission of the repeated uplink signal is configured, information indicating the selected code sequence by using a field for indicating a cyclic shift and an orthogonal sequence used for the demodulation reference signal. A terminal receives information indicating one of a plurality of code sequences orthogonal to one another using a field for indicating a cyclic shift and an orthogonal sequence used for a demodulation reference signal and multiplies an uplink signal including the demodulation reference signal repeated in a plurality of subframes by the code sequence indicated by the information.

Abstract: Provided are an eNB, a UE and wireless communication methods. The eNB, in an embodiment, includes circuitry operative to fill a SPS activation/deactivation field in a DCI with a predetermined pattern of bits; and a transmitter operative to transmit the DCI to a first UE for the first UE to start periodically transmitting signals to a second UE or stop periodically transmitting signals to the second UE based on the SPS activation/deactivation field. The DCI is in a SPS format formed by adopting part or all bits of at least one field of DCI format 5 as the SPS activation/deactivation field, and information supposed to be transmitted in the at least one field is indicated with the assistance of or by RRC or MAC signaling.

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 repeater generates repetition signals by repeating uplink signals over a plurality of subframes; controller sets a timing for transmitting the repetition signals, based on information indicating a transmission candidate subframe for a sounding reference signal used for measuring an uplink reception quality; and a transmitter transmits the repetition signals at the set timing.

Abstract: Wireless communication methods and devices are provided. The wireless communication method includes transmitting a reference signal and a data signal in a Physical Resource Block (PRB) with a coverage enhancement level, wherein the number of resource elements transmitting the reference signal in the PRB is determined by the coverage enhancement level, the channel type and/or the coding rate of the data signal.

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: If repetition transmission is applied to a response signal for a downlink data signal and an uplink signal, the uplink signal is repeatedly transmitted using a certain number of consecutive subframes starting with a first subframe, at which the repetition transmission of the uplink signal starts, and the response signal is repeatedly transmitted using at least the certain number of consecutive subframes starting with a second subframe, at which the repetition transmission of the response signal starts. The first subframe is set to be the same as the second subframe.

Abstract: Repetitions of a control signal across a plurality of first subframes and a data signal allocated to a resource indicated by the control signal are received. Repetition of a response signal for the data signal across a plurality of second subframes is performed, and a transmission signal is generated by multiplying the response signals in the second subframes by, among a plurality of first sequences orthogonal to one another, components of one of the first sequences which is associated with the first subframes, respectively.

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.
