Abstract

本申请提供了一种背向散射通信方法及装置，该方法包括：发送设备接收基站发送的唤醒wakeup信号；所述发送设备根据所述wakeup信号确定待发送数据的发送起始时刻；所述发送设备在从所述发送起始时刻起的第k个发送时间间隔内，根据所述待发送数据中第k个比特值，对所述基站发送的激励信号进行散射处理，所述散射处理为散射所述基站发送的激励信号或者不散射所述激励信号，k＝1,2,……n，n为所述待发送数据所包含的比特数量。本申请的发送设备可以根据待发送比特值对基站发送的激励信号进行相应地散射处理，以使接收设备根据该发送时间间隔内接收到的信号的能量确定相应的比特值，从而利用基站发送的激励信号完成低功耗或零功耗的背向散射通信。本实施例提供的方法提高了网络的覆盖能力，可以应用于物联网，例如MTC、IoT、LTE‑M，M2M等。
