本发明实施例中的第一资源配置信息用于指示M个第一频率资源和N个第二频率资源，M、N为大于或等于1的正整数。本发明实施例中的随机接入请求包括随机接入信道(Physical Random Access Channel，PRACH)。
随机接入过程有两种不同的方式：基于竞争(Contention based)的随机接入和基于非竞争(Non-Contention based或Contention-Free based)的随机接入。
针对基于竞争的随机接入和基于非竞争的随机接入，网络设备为终端配置的第一资源配置信息均包括：随机接入请求的发送资源配置信息和随机接入响应的接收资源配置信息。其中，随机接入请求的发送资源配置信息包括M个第一频率资源中每个第一频率资源的参数信息，用于指示M个第一频率资源，随机接入响应的接收资源配置信息包括N个第二频率资源中每个第二频率资源的参数信息，用于指示N个第二频率资源。

需要说明的是，上述的M与N可以相同也可以不相同，此处不做限定。此外，上述的M个第一频率资源和N个第二频率资源可以为相同频率资源，也可以为不同频率资源，此处不做限定。
假设上述的M个第一频率资源和N个第二频率资源为相同频率资源，即网络设备为 随机接入过程中的各个消息分配的频率资源相同，此时，第一资源配置信息指示的频率资源的数量大于或等于2。同理，针对基于竞争的随机接入过程，上述的M、N、K以及L的值可以相同也可以不同，上述的M个第一频率资源、N个第二频率资源、K个第三频率资源以及L个第四频率资源可以为相同频率资源，也可以为不同频率资源，此处不做限定。
