    摘要: The present invention provides a base station, a terminal device, a communication system, and a communication method configured to efficiently specify a physical uplink control channel resource in a case that the base station notifies the terminal device of control information through an enhanced physical downlink control channel or in a case that a cell radius is small. The terminal device in communication with the base station monitors a physical downlink control channel placed in a common search space and an enhanced physical downlink control channel placed in a terminal-specific search space. Upon detecting the enhanced physical downlink control channel, the terminal device maps response information to a physical uplink control channel resource determined in response to at least an index of an element forming the detected enhanced physical downlink control channel and an individual shift amount individually configured on a per terminal device basis, and then reports the base station of the mapped response information.

    摘要: 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.

    摘要: In a radio communication system in which a base station and a terminal communicate with each other, the base station efficiently transmits control information to the terminal.The base station that communicates with the terminal using resource blocks, each of which is constituted by a prescribed time region and a prescribed frequency region, includes a terminal-specific control channel generation unit that generates terminal-specific control channels mapped in a terminal-specific control channel region constituted by a prescribed number of resource blocks and transmitted using the same antenna port as for terminal-specific reference signals, which are reference signals specific to the terminal. The resource blocks in the terminal-specific control channel region are divided into a plurality of resource element groups, and the terminal-specific control channels are mapped in the resource element groups using a distributed mapping rule, in which the terminal-specific control channels are mapped in such a way as to be distributed among a plurality of resource blocks, or a localized mapping rule, in which the terminal-specific control channels are mapped in one of the resource blocks in a localized manner.

    摘要: The present invention enables a signal containing control information to be efficiently transmitted and received between a base station apparatus and a mobile station apparatus. The mobile station apparatus includes a first control unit configured to control, for a localized EPDCCH which is an EPDCCH constituted by a resource of one PRB pair, the EPDCCH being constituted by an aggregation of one or more ECCEs, a plurality of PRB pairs being configured as a region to which the EPDCCH is to be possibly mapped, an antenna port associated with a reference signal used for demodulation of a signal mapped to a corresponding ECCE constituted by a resource obtained by dividing the PRB pair.
