WIPO Patent Application WO/2021/230213
Kind Code:
A1
Abstract:
A user equipment (UE) is described. The UE includes higher layer circuitry configured to receive first information for a first frequency band, and second information for a second frequency band. The UE also includes reception circuitry configured to receive a demodulation reference signal (DMRS) and a phase tracking reference signal (PTRS). Resources of a PTRS in the first frequency band are determined by a first parameter of the first information, and resources of a PTRS in the second frequency band is determined by a second parameter of the second information.
