UE 根據(jù)在子幀中檢測(cè)到的具有DCI 格式1 ，1A ，1B ，1C ，1D ，2,2A 或者UE 擴(kuò)展的DCI 格式2B 的PDCCH ，使用上層定義的傳輸塊數(shù)目限制條件來(lái)解碼在同一子幀中相應(yīng)的PDSCH 。
UE 可能設(shè)想定位參考信號(hào)不在根據(jù)用DCI 格式1A 或者1C 的SI-RNTI 或者P-RNTI 做CRC 擾碼的PDCCH 解碼的PDSCH 的資源塊中出現(xiàn)。
如果UE 被高層設(shè)置解碼具有用SI-RNTI 擾碼CRC 的PDCCH 時(shí)，UE 將根據(jù)表7.1-1 中定義的任意組合來(lái)解碼PDCCH 和對(duì)應(yīng)的PDSCH 。對(duì)應(yīng)于這些PDCCH 的PDSCH 用SI-RNTI 來(lái)進(jìn)行擾碼初始化。
盲檢測(cè)與DCI 和RNTI 關(guān)系如下多張表：
