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，或可用于智能驾驶，智能网联车等领域。第一终端装置在K1个方向上向第二终端装置发送K2个第一参考信号，第一终端装置确定，连续N1次，K1个方向上的波束均失败。第一终端装置在P1个方向上向第二终端装置发送P2个第二参考信号，第一终端装置根据来自第二终端装置的P2个第二参考信号的测量结果，确定P1个方向对应的P1个波束是否可用。可见，本申请实施例提供了在SL通信中进行波束失败检测的机制。另外，本申请实施例可以尽量通过物理层对波束进行恢复，无需通过高层，提高了波束恢复的效率，也减小了因波束失败而导致的业务时延。
