Abstract

本申请提供一种PBCH传输方法及装置。该方法包括：终端设备接收网络设备发送的PBCH，该PBCH中包括的PBCH所在无线帧的SFN的最高7位，终端设备根据SFN的最低一位的指示信息，确定PBCH的最低一位，终端设备根据PBCH，确定PBCH的扰码、CRC校验掩码或者冗余版本中的至少一种，并根据SFN的剩余两位与PBCH的扰码、CRC校验掩码或者冗余版本中的至少一种的一一对应关系，确定SFN的剩余两位，终端设备根据SFN的最低一位、最高7位、第二低位和第三低位确定PBCH所在无线帧的SFN，实现了减少盲检测复杂度，同时，可以适用于一个PBCH TTI中不同的PBCH发送次数的场景，适用范围较广。
