Patent ID: 11005597

Abstract:
A wireless transmit receive unit (WTRU) may receive a Physical Downlink Control Channel (PDCCH) transmission and perform early termination on the PDCCH transmission. Transmissions that are not intended for the WTRU may be terminated. The WTRU may perform a first decode of the PDCCH transmission based on a first scrambling sequence. The first scrambling sequence may be generated using a Gold sequence, which may be initialized based on a WTRU identifier. If the first decode is not successful, the WTRU may determine that the PDCCH transmission is not intended for the WTRU. The WTRU may perform an assistance bit added (ABA) polar decode of the PDCCH transmission based on a second scrambling sequence (e.g., a cell radio network temporary ID (C-RNTI)). The WTRU may perform a CRC on the output of the ABA polar decode to obtain downlink control information (DCI).
