Title:
端末装置、基地局装置および通信方法
Document Type and Number:
Japanese Patent JP6503563
Kind Code:
B2
Abstract:
A terminal device that communicates with a base station device, comprising: a control unit configured to set information related to a transmission time interval (TTI) based on signaling from the base station device; and a receiving unit configured to receive a first physical downlink shared channel (PDSCH) that is mapped in a first TTI mode or a PDSCH that is mapped in a second TTI mode and a demodulation reference signal, based on the information related to the TTI. The first TTI mode is a mode in which one PDSCH is mapped within a time resource defined by a predetermined number of symbols, and the second TTI mode is a mode in which two or more PDSCHs can be mapped in the time resource
