Abstract

A method of wireless communication is provided which includes determining a first cell identification (ID) for scrambling a first reference signal of a first enhanced physical downlink control channel (EPDCCH) and determining a second cell ID for scrambling a second reference signal of a second EPDCCH. The second cell ID is based at least in part on the first cell ID. The first reference signal and the second reference signal are mapped to a same set of resources. The method also includes transmitting the first EPDCCH and second EPDCCH.
