Abstract
A method for determining a dedicate searching space (DSS) in a physical downlink control channel (PDCCH) for a user equipment (UE) of a wireless communication system is disclosed. The method includes steps of 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 the DSS utilized for monitoring the SPS C-RNTI according to a cell radio network temporary identifier (C-RNTI) of the UE.
Claims10
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:
- the UE monitoring 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 by:
- 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;
- and
- performing cyclic redundancy check demasking (CRC demasking) operation on the blind decoding result according to the SPS C-RNTI.
A communication device 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 communication device comprising:
- a processor for executing a program code;
- and
- a storage device, coupled to the processor, for storing the program code, wherein the program code comprises:
- the UE monitoring 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 by:
- 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;
- and
- performing cyclic redundancy check demasking (CRC demasking) operation on the blind decoding result according to the SPS C-RNTI.
