Abstract
(EN) A signal sending and receiving method and device, used for improving the accuracy of a terminal device adjusting a frequency offset. The signal sending method comprises: a network device determining an SSB and indication information, wherein the indication information is used for indicating that a frequency location of the SSB is one of a frequency set, the frequency set comprising a first frequency and a second frequency, or a first frequency, a second frequency and third frequency; the network device sending the SSB and the indication information to the terminal device.
(FR) L'invention concerne un procédé et un dispositif d'envoi et de réception de signal aptes à améliorer la précision avec laquelle un dispositif terminal ajuste un décalage de fréquence. Le procédé d'envoi de signal comprend les étapes suivantes : un dispositif de réseau détermine un SSB et des informations d'indication, les informations d'indication étant utilisées pour indiquer qu'un emplacement de fréquence du SSB est l'un d'un ensemble de fréquences, l'ensemble de fréquences comprenant une première fréquence et une seconde fréquence ou bien une première fréquence, une deuxième fréquence et une troisième fréquence ; et le dispositif de réseau envoie le SSB et les informations d'indication au dispositif terminal.
(ZH) 一种信号发送、接收方法及设备,用于提高终端设备调整频率偏移的准确度。其中的一种信号发送方法包括:网络设备确定SSB和指示信息,其中,所述指示信息用于指示所述SSB的频率位置为频率集合中的一个,所述频率集合包括第一频率和第二频率,或者第一频率、第二频率以及第三频率;所述网络设备向终端设备发送所述SSB和所述指示信息。
