Abstract

本申请公开了一种随机接入方法、终端设备和网络设备,涉及通信技术领域,能够实现终端设备如何在2‑step RACH和4‑step RACH两种随机接入类型中选择其中一种进行随机接入。其方法为:终端设备接收网络设备发送的配置信息,配置信息包括至少一个阈值,至少一个阈值包括第一阈值和第二阈值,第一阈值用于终端设备选择随机接入类型,第二阈值用于终端设备在多个下行参考信号中选择一个下行参考信号,第二阈值为参考信号的接收功率RSRP阈值;终端设备根据至少一个阈值确定随机接入类型以及一个下行参考信号;终端设备根据确定的下行参考信号确定一个随机接入传输机会;终端设备在随机接入传输机会上发送随机接入类型的消息。本申请实施例用于5G NR场景下的随机接入过程。
