Title (EN) METHOD AND DEVICE FOR TRANSMITTING REFERENCE SIGNAL
(FR) PROCÉDÉ ET DISPOSITIF DE TRANSMISSION DE SIGNAL DE RÉFÉRENCE
(ZH) 参考信号的传输方法及装置
Abstract:
(EN) Disclosed are a method and device for transmitting a reference signal. The method comprises: generating one or more OFDM symbols, at least one of the OFDM symbols comprising a PTRS resource block, the PTRS resource block comprising at least two of: Y elements of a PTRS sequence, X final elements of the PTRS sequence, and Z initial elements of the PTRS sequence, and the PTRS resource block occupying multiple continuous resource elements (RE), wherein each of X, Y and Z is an integer; and transmitting the one or more OFDM symbols. The above method and device can reduce inter-carrier interference, thereby increasing spectral efficiency.
(FR) L'invention concerne un procédé et un dispositif de transmission de signal de référence. Le procédé consiste à : générer un ou plusieurs symboles OFDM, au moins l'un des symboles OFDM comprenant un bloc de ressources PTRS, le bloc de ressources PTRS comprenant au moins deux éléments parmi : Y éléments d'une séquence PTRS, X éléments finaux de la séquence PTRS et Z éléments initiaux de la séquence PTRS, et le bloc de ressources PTRS occupant de multiples éléments de ressources continus (RE), chacun de X, Y et Z étant un nombre entier; et transmettre le ou les symboles OFDM. Le procédé et le dispositif ci-dessus permettent de réduire l'interférence entre porteuses, ce qui permet d'augmenter l'efficacité spectrale.
(ZH) 本申请公开了一种参考信号的传输方法及装置,该方法包括:生成一个或多个OFDM符号,至少一个OFDM符号包括PTRS资源块,所述PTRS资源块包括Y个元素的PTRS序列,所述PTRS序列的后X个元素,PTRS序列的前Z个元素这三个序列中的至少两个,所述PTRS资源块占用连续的多个资源元素RE;其中,X,Y,Z均为整数;发送所述一个或多个OFDM符号;上述方法及装置,减小载波间干扰,进而提高频谱效率。
