Cell ID and antenna port configurations for EPDCCH

摘要

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.

主权项

1. A method of wireless communication, comprising:
determining whether a first set of resource elements for a first reference signal, for at least a first user equipment (UE), of a first enhanced physical downlink control channel (EPDCCH) and a second set of resource elements for a second reference signal, for at least a second UE, of a second EPDCCH are selected from a same plurality of resource elements, and in which the first reference signal and the second reference signal are transmitted from a same set of antenna ports; determining a cell identification (ID) for scrambling the first reference signal and for scrambling the second reference signal when the first set of resource elements and the second set of resource elements are selected from the same plurality of resource elements, the first set of resource elements being different from the second set of resource elements; and transmitting the first EPDCCH and the second EPDCCH.
