技术领域
本公开涉及通信技术领域，具体涉及一种随机接入资源的配置方法和设备。

参见图1，两步随机接入(2-Step RACH(Random Access Channel))的流程包括：
步骤0：网络设备给终端设备配置两步随机接入的配置信息；
例如：配置信息包括：消息1(Msg1)和消息2(Msg2)对应的发送资源信息。
步骤1：终端设备触发2-step RACH过程。
将请求信息(例如：Msg1)发送给网络设备，例如：通过物理上行共享信道(Physical Uplink Shared Channel，PUSCH)发送。
步骤2：网络设备发送确认信息(例如：Msg2)给终端设备。
如果终端设备接收Msg2失败，则终端设备重新发送Msg1。
在2-step RACH的过程中，如果复用常规(normal)RACH的所有资源，则需要联合考虑存量终端设备和新终端设备支持2-step RACH的情况，导致随机接入响应(Random Access Response，RAR)的设计会非常复杂。
