Abstract:
(EN) This terminal device is provided with: a multiplexing unit that maps a phase tracking reference signal (PTRS) to a resource of a physical uplink shared channel (PUSCH) in accordance with a first pattern, and maps a demodulation reference signal (DMRS) to the resource of the PUSCH in accordance with a second pattern; and a transmission unit that transmits the PUSCH, to the resource of which the PTRS and the DMRS are mapped, wherein if a symbol position of the PTRS and a symbol position of the DMRS overlap, the multiplexing unit maps the PTRS to a resource at a symbol position different from the overlapping symbol position.
(FR) La présente invention concerne un dispositif terminal comprenant : une unité de multiplexage qui établit une correspondance entre un signal de référence de suivi de phase (PTRS) et une ressource d'un canal partagé à liaison montante physique (PUSCH) conformément à une première configuration et établit une correspondance entre un signal de référence de démodulation (DMRS) et la ressource du PUSCH conformément à une seconde configuration; et une unité de transmission qui transmet le PUSCH, à la ressource mise en correspondance avec le PTRS et le DMRS. Si une position de symbole du PTRS et une position de symbole du DMRS se chevauchent, l'unité de multiplexage établit une correspondance entre le PTRS et une ressource sur une position de symbole différente de la position de symbole chevauchante.
(JA) PTRS(Phase Tracking Reference Signal)を第1のパターンに従ってPUSCH(Physical Uplink Shared Channel)のリソースにマッピングし、DMRS(Demodulation Reference Signal)を第2のパターンに従って前記PUSCHのリソースにマッピングする多重部と、前記PTRSと前記DMRSとがリソースにマッピングされた前記PUSCHを送信する送信部と、を備え、 前記多重部は、前記PTRSのシンボル位置と前記DMRSのシンボル位置とがオーバラップする場合には、前記PTRSをオーバラップするシンボル位置とは異なるシンボル位置のリソースにマッピングする。
