Reference signals for an enhanced physical downlink control channel

摘要

A method of wireless communication includes generating a first reference signal (e.g., DM-RS) based on a first scrambling identifier. The method also includes generating a second reference signal (e.g., DM-RS) based on a second scrambling identifier. The second scrambling identifier is different from the first scrambling identifier. The method further includes transmitting the first reference signal for a control channel (e.g., EPDCCH) and transmitting the second reference signal for a data channel (e.g., PDSCH).

1. A method of wireless communication, comprising:
generating a demodulation reference signal (DM-RS) based at least in part on a single scrambling identifier (ID) having a value of 2; generating a user equipment specific reference signal (UE-RS) based at least in part on a single scrambling ID having a value of 0 or 1, the value of the single scrambling ID for the DM-RS being different from the value of the single scrambling ID of the UE-RS such that the DM-RS is distinguishable from the UE-RS; transmitting the DM-RS for an enhanced control channel that uses resources selected from at least a data region of a subframe; and transmitting the UE-RS for a data channel that uses resources selected from the data region.
