Abstract

本发明实施例提供了一种随机接入配置方法、信号发送方法、装置和系统，所述随机接入配置方法包括：网络设备发送第一指示信息，所述第一指示信息包括以下信息的至少一项：随机接入信道配置索引(第一索引)；时域相邻的随机接入资源的时间间隔；不可用的随机接入资源；一个随机接入资源的至少两个时域起始位置；一个随机接入资源的时域结束位置；信道接入的尝试次数；以及信道接入的类型。由此，通过上述随机接入配置方法保证了相邻的随机接入资源之间有足够的间隔或者更多的机会进行信道检测，终端设备可以据此进行信道检测并在一个随机接入资源发送msg.1，有效避免了资源浪费，降低了随机接入时延，并提高了频谱效率。
