Patent ID: 8326292

Claim:
A method for determining a dedicate searching space (DSS) of a physical downlink control channel (PDCCH) in a user equipment (UE) of a wireless communication system, the method comprising: indicating the UE to monitor a semi-persistent scheduling cell radio network temporary identifier (SPS C-RNTI) in the PDCCH, for receiving a semi-persistent scheduling grant; and determining a common DSS for monitoring both the SPS C-RNTI and a cell radio network temporary identifier (C-RNTI) of the UE according to the C-RNTI; wherein the step of monitoring the SPS C-RNTI comprises: performing blind decoding in the common DSS for generating a blind decoding result for both the SPS C-RNTI and the C-RNTI of the UE at one time; and performing cyclic redundancy check demasking (CRC demasking) operation on the blind decoding result according to the SPS C-RNTI.
