Abstract

一种随机接入方法，数据接收方法及其装置、通信***。其中，该随机接入方法包括：终端设备向网络设备发送随机接入前导；在该终端设备接收到第一通知时，或者在该终端设备接收到第一通知，且满足与该随机接入前导相关的第一小区的条件时，该终端设备确定(consider)与该随机接入前导相对应的随机接入过程成功完成；其中，该第一通知是从底层发送的收到在该第一小区的下行控制信道传输的通知，和/或从底层发送的收到为了反馈该随机接入前导的下行控制信道传输的通知，通过本发明实施例，根据下行控制信道传输与小区或终端设备发送的随机接入前导的关系确定随机接入过程是否成功，由此终端设备能够准确的收发数据，从而提高成功率，减少重传次数，进而节省能耗。
