Abstract
A method for monitoring a control channel in a wireless communication system and a wireless device using the same are provided. The wireless device monitors a downlink control channel in at least one physical resource block (PRB) pair of a subframe that is assigned for an enhanced physical downlink control channel (EPDCCH) set. A beatstream for downlink control information of the downlink control channel is scrambled by a scrambling sequence that is initialized on the basis of a scrambling initialization value allocated to the EPDCCH set.
Claims13
A method for monitoring a control channel in a wireless communication system, the method comprising:
- monitoring, by a wireless device, a downlink control channel in at least one physical resource block-pair of a subframe that is assigned for an enhanced physical downlink control channel (EPDCCH) set,
- wherein a bit stream for downlink control information on the downlink control channel is scrambled with a scrambling sequence that is initialized based on a scrambling initialization value assigned for the EPDCCH set.
A device configured to monitor a control channel in a wireless communication system, the device comprising:
- a processor;
- and
- a memory operatively coupled with the processor and storing instructions that when executed by the processor causes to the device to monitor a downlink control channel in at least one physical resource block-pair of a subframe that is assigned for an enhanced physical downlink control channel (EPDCCH) set,
- wherein a bit stream for downlink control information on the downlink control channel is scrambled with a scrambling sequence that is initialized based on a scrambling initialization value assigned for the EPDCCH set.
A method for transmitting downlink control information in a wireless communication system, performed by a base station, the method comprising:
- generating a bit stream for downlink control information;
- generating a scrambling sequence;
- scrambling the bit stream for the downlink control information with the scrambling sequence;
- and
- transmitting the scrambled bit stream in at least one physical resource block-pair of a subframe that is assigned for an enhanced physical downlink control channel (EPDCCH) set,
- wherein the scrambling sequence is initialized based on a scrambling initialization value assigned for the EPDCCH set.
