Abstract: A terminal device decodes a code block of a transport block, and in a case that a first transmission mode is configured, a rate matching for the code block is processed based on a first total number of soft channel bits; in a case that a second transmission mode is configured and first information is configured, a rate matching for the code block is processed based on the first total number of soft channel bits; and in a case that the second transmission mode is configured and the first information is not configured, a rate matching for the code block is processed based on a second total number of soft channel bits. Here, the first information indicates the maximum number of layers associated with PDSCH transmission.

Abstract: There is provided a terminal for performing OFDM (Orthogonal Frequency-Division Multiplexing) communication with a base station forming a cell. The terminal includes a control channel processing unit configured to monitor, in a sub-frame, a first control channel in a cell-specific search space that is a search space common within the cell, and a first control channel in a UE-specific search space that is a search space specific to the terminal. In a case where monitoring of a second control channel different from the first control channel that is in the cell-specific search space or the UE-specific search space is configured, the control channel processing unit monitors, in a sub-frame, at least both the first control channel in the cell-specific search space and the second control channel in the UE-specific search space.

Abstract: A terminal that communicates with a base station monitors a physical downlink control channel allocated in a physical downlink control channel region and an enhanced physical downlink control channel allocated in a physical downlink shared channel region different from the physical downlink control channel region. If the enhanced physical downlink control channel is detected, the terminal reports response information via a physical uplink control channel resource corresponding to the resource in which the enhanced physical downlink control channel was detected.

Abstract: A terminal device that communicates with a base station apparatus includes a transmission unit that transmits a channel and/or a signal based on a maximum output power in a first cell group in a certain subframe. In a case where information relating to uplink transmission in the second cell group is recognized, a residual power is allocated based on a priority level of a type of uplink transmission. The residual power is given by subtracting a power that is determined based on uplink transmission in the first cell group and a power that is determined based on the uplink transmission in the second cell group from a sum of maximum output powers of the terminal device. The maximum output power is a sum of the power that is determined based on the uplink transmission in the first cell group and a power that is allocated to the first cell group, of the residual power.

Abstract: By effective knowledge or information about an interfering signal, interference is mitigated. A base-station apparatus communicating with a terminal apparatus includes a higher layer processing circuitry that configures, to the terminal apparatus, CRS assistance information used by the terminal apparatus to mitigate interference from a cell-specific reference signal, in which in a case where a predetermined parameter including information about a DL/UL subframe configuration and information about a MBSFN subframe is configured, the higher layer processing circuitry does not configure the CRS assistance information to the terminal apparatus.
