Abstract
提供了一种用于随机接入的方法、终端设备和网络设备。该方法包括：该终端设备向网络设备发送前导序列和小区接入无线网络临时标识符媒体接入控制控制元素C‑RNTI MAC CE，其中该C‑RNTI MAC CE包括C‑RNTI；该终端设备盲检用该C‑RNTI加扰的物理下行控制信道PDCCH；该终端设备根据该C‑RNTI的盲检结果，确定是否已解决两步随机接入过程中的竞争冲突。本申请实施例中，网络设备根据该前导序列的解码结果和该C‑RNTI MAC CE的解码结果向该终端设备发送PDCCH，进而终端设备可以通过盲检用该C‑RNTI加扰的PDCCH，确定是否已解决两步随机接入过程中的竞争冲突。
