Abstract: An object of this disclosure is to improve the channel estimation accuracy without degradation of transmission quality. Control section (101) configures a predefined number of demodulation reference signals (DMRSs) for terminal (200) configured to perform repetition of an uplink signal over multiple subframes, when a coverage enhancement level corresponding to the number of the multiple subframes is smaller than a determined value, and configures, for the terminal, a number of DMRSs obtained by adding a predetermined number of DMRSs to the predefined number, when the terminal applies the repetition and the coverage enhancement level is equal to or larger than the determined value, the uplink signal being formed by time-multiplexing a data symbol with a DMRS in one subframe. Receiving section (110) receives the uplink signal including the configured number of DMRSs and transmitted from the terminal. Channel estimation section (115) performs channel estimation using the DMRS included in the received uplink signal.

Abstract: The invention relates to transmission and reception of data in a wireless communication system. In particular, the predetermined number of repetitions of the same data portion is transmitted over the wireless interface. The receiving device receives the repetitions, attempts their decoding and checks whether the decoding was successful. If the decoding was successful after the predetermined number of repetitions or less, a positive acknowledgement is generated. In addition, a feedback including a bundle size information is generated and transmitted. The bundle size information includes a number of repetitions, smaller or equal to the predetermined number, after which the decoding was successful. The feedback is transmitted to the data transmitting device which may adapt the predetermined number of repetitions accordingly. The invention enables efficient control of the number of repetitions applied which is particularly advantageous for coverage enhancement purposes.

Abstract: Provided is a terminal apparatus that, when two terminals having mutually different subframe structure patterns are coexistent, can suppress DCI scheduling constraints of those terminals in a base station. In a terminal (200), a signal separation unit (203) separates, from a received signal, both a response signal assigned to a first resource determined on the basis of a number of resources associated with the first subframes in which the signal was received and downstream control information assigned to a second resource. It should be noted that at a timing when both a first structure pattern that has been set in the terminal (200) and a second structure pattern that has been set in another terminal that cannot change the setting of the structure pattern are the first subframes, the signal separation unit (203) uses a number of resources associated with the first subframes of the second structure pattern.

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: 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.
