Classification: CPC H | IPC H

Claim 20:
21. A method comprising:
generating, by an apparatus, downlink control information (DCI) indicating an antenna port set of pilots used for data demodulation,
wherein the antenna port set comprises at least one first antenna port and at least one second antenna port, and
wherein the at least one first antenna port is for a terminal, and the at least one second antenna port is not for the terminal; and sending, by the apparatus, the DCI to the terminal,
wherein a ratio of energy per resource element (EPRE) of a physical downlink shared channel (PDSCH) to EPRE of a demodulation reference signal (DMRS) of the PDSCH is determined based on the antenna port set, and
wherein a larger quantity of resources for antenna ports in the antenna port set is associated with a smaller value of the ratio.
