Abstract:
To provide a base station apparatus, a terminal apparatus, and a communication method, capable of increasing the number of terminal apparatuses that can be spatially multiplexed by the base station apparatus in uplink. A base station apparatus according to an aspect of the present invention is a base station apparatus for communicating with multiple terminal apparatuses, the base station apparatus including a transmission unit configured to notify the terminal apparatuses of DMRS configuration information of DMRSs transmitted over multiple subframes. In addition, a terminal apparatus according to the aspect of the present invention includes: a reception unit that acquires the DMRS configuration information of the DMRSs transmitted across the multiple subframes, notified by the base station apparatus; an uplink reference signal generation unit that generates the DMRSs transmitted across the multiple subframes, based on the DMRS configuration information; and a transmission unit that transmits the DMRSs.

Claim (Index 19):
A communication method for a base station apparatus configured to communicate with a terminal apparatus, the communication method comprising:\n transmitting, to the terminal apparatus, a cyclic shift field indicating one of a plurality of values related to a demodulation reference signal (DMRS), the cyclic shift field being transmitted by means of downlink control information (DCI) which is carried by a physical downlink control channel (PDCCH), and receiving the DMRS, wherein the DMRS is defined by using first information indicating cyclic shift quantities, second information indicating an orthogonal cover code (OCC), and third information indicating a frequency domain allocation, the frequency domain allocation being repeated in every two subcarriers, and the first information corresponds to the one of the plurality of values, and the second information and the third information are related to the first information.
