1. 設計 1: 一個 UE 的所有的 PDCCHs 在 PDCCH Active component carrier 的一個載波上傳輸,因此 PDCCH 被阻擋的機率大增。2. 設計 2: 一個 UE 的所有的 PDCCHs 在 PDCCH Active component carrier 的部分的載波上傳輸,因此 PDCCH 被阻擋的機率較小。3. 設計 3: 一個 UE 的所有的 PDCCHs 在 PDCCH Active component carrier 的全部的載波上傳輸,因此 PDCCH �們得到以下結論: PDCCH 的阻擋機率是設計 1 大於設計 2 大於設計 3 “PDCCH Active CC Set”提供了 PDCCH 的阻擋率與 PDCCH 的瞎眼解碼法複雜度的靈活性7.3.
