Abstract

本申请提供一种确定数据传输反馈时延的方法及装置。网络设备确定在第一时频资源上发送调度第一数据信道的第一控制信道以及在第二时频资源上发送承载第一数据的第一数据信道，当确定终端设备在处理第一数据之前需要丢弃第二数据时，网络设备根据第一时频资源和第二时频资源的相对位置关系、终端设备丢弃第二数据所需的时长与第一时长的大小关系确定第一数据的反馈时延；进而，网络设备在第一时频资源上向终端设备发送第一控制信道以及在第二时频资源上向终端设备发送第一数据信道；其中，第一时长为第一时频资源的结束时刻和第二时频资源的起始时刻之间间隔的时长。采用上述方法，可以避免确定的反馈时延过长，从而提升数据传输的性能。
