Abstract
一种随机接入前导码发送方法及设备，该方法包括：终端设备获取网络设备发送的随机接入配置信息，随机接入配置信息用于指示随机接入前导码的格式；终端设备根据随机接入配置信息和预设规则，确定向网络设备发送的随机接入前导码的频点信息；终端设备根据频点信息，按照格式向网络设备发送随机接入前导码；其中，随机接入前导码由L个符号组组成，L为大于4的正整数，每相邻两个符号组之间存在跳频，每个符号组通过一个子载波频点发送，频点信息包括L个符号组分别对应的频点。上述随机接入前导码的符号组的单载波发送方式，以及根据新格式确定的频点信息，能够使终端设备适应NB‑IoT系统支持更窄的子载波带宽以及覆盖更大的小区半径的应用场景。
