Title:
TERMINAL DEVICE, BASE STATION DEVICE, AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/139575
Kind Code:
A1
Abstract:
According to the present invention, in a case where PUSCH transmission is PUSCH transmission of a two-step contention-based random access procedure, a complex value symbol is not mapped in a resource element of the last one or the last two or more prescribed SC-FDMA symbols of a prescribed sub-frame. In a case where the PUSCH transmission is not the PUSCH transmission of the two-step contention-based random access procedure and a first field (a PUSCH ending symbol) included in downlink control information for giving an instruction for the PUSCH transmission indicates 1, the complex value symbol is not mapped in the resource element of the last SC-FDMA symbol of the prescribed sub-frame.
