Abstract
本申请涉及一种通信方法及装置，可应用于车联网，例如V2X、LTE‑V、V2V等，或用于智能驾驶，智能网联车等领域。从第一资源集中确定第一资源，在N个候选资源中的第j候选资源上发送N个同步信号块中的第j同步信号块。第一资源集包括M个组，M个组中的第i组包括X个候选资源。第一资源集包括的M×X个候选资源可用于传输同步信号块。N个同步信号块中的每个同步信号块在时域上占用Y个符号，Y为大于等于5的整数。第一资源包括N个候选资源，N个候选资源属于M个组中的一组或多组。一个同步信号块占用Y个符号，使得本申请实施例能够应用于NR‑V2X系统，或者可以应用于其他的规定了同步信号块占用Y个符号的通信系统。
