First Claim
Patent Images
1. 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.

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.
