作为一种示例,假设每个SPS PDSCH对应1比特,N个SPS PDSCH资源需要N比特,在non-skipped SPS PDSCH且对应NACK的位置标志1,其余位置填充0。或者,在non-skipped SPS PDSCH且对应NACK的位置标志0,其余位置填充1,在此不做限定。
需要解释的是,由于N是确定的,反馈开销不会随着N窗口内SPS PDSCH时机传输次数的改变而改变。
作为一种可能的实现方式,UE可以获取N个SPS PDSCH资源之中non-skipped SPS PDSCH的实际传输次数M,生成具有M位的位图。
其中,具有M位的位图之中,在non-skipped SPS PDSCH且对应NACK反馈的位置对应第一标志,位图的其他位置对应第二标志。

可以理解为,non-skipped SPS PDSCH的实际传输时,传输功率会发生变化,实际传输数据的功率较高,未传输数据的功率较低,因此,可以根据N个SPS PDSCH资源之中每个non-skipped SPS PDSCH的传输功率,确定SPS PDSCH资源是否进行了一次实际传输。

作为本公开实施例的另一种可能的实现方式,实际传输次数M还可以是网络侧设备通过显示指示的方式确定的。
例如,网络侧设备可以直接通过DCI动态指示M值,每N个单位指示一次。
