1. A method for communication in a wireless communications network, the method comprising:
- transmitting, by a network element in a first cell, a first demodulation reference signal (DMRS) on a first DMRS port;
transmitting, by the network element, a first physical downlink shared channel (PDSCH) on the first DMRS port; and
transmitting, by the network, information indicating that the first DMRS port is used to transmit the first PDSCH, and information about a second DMRS port that is not used to transmit the first PDSCH but is used to transmit a second DMRS, wherein the first DMRS and the second DMRS are orthogonal to one another.

Abstract
A method for communication in a wireless communications network is provided. The method comprises: transmitting, by a network element in a first cell, a first DMRS on a first DMRS port; transmitting, by the network element, a first PDSCH on the first DMRS port; and transmitting, by the network, information indicating that the first DMRS port is used to transmit the first PDSCH, and information about a second DMRS port that is not used to transmit the first PDSCH but is used to transmit a second DMRS, wherein the first DMRS and the second DMRS are orthogonal to one another.

12. A method for communication in a wireless communications network, the method comprising:
-
receiving, by a user equipment (UE) that identifies itself as capable of performing interference mitigation, a first demodulation reference signal (DMRS) on a first DMRS port transmitted from a first cell; receiving, by the UE, a physical downlink shared channel (PDSCH) on the first DMRS port; and receiving, by the UE, information indicating that the first DMRS port is used to transmit the PDSCH, and information about a second DMRS port that is not used to transmit the PDSCH but is used to transmit a second DMRS, wherein the first DMRS and the second DMRS are orthogonal to one another. - View Dependent Claims (13, 14, 15, 16)

17. A user equipment (UE) comprising:
a processor configured such that the UE receives a first demodulation reference signal (DMRS) on a first DMRS port transmitted from a first cell, further configured such that the UE receives a physical downlink shared channel (PDSCH) on the first DMRS port, and further configured such that the UE receives information indicating that the first DMRS port is used to transmit the PDSCH, and information about a second DMRS port that is not used to transmit the PDSCH but is used to transmit a second DMRS, wherein the first DMRS and the second DMRS are orthogonal to one another, and wherein the UE identifies itself as capable of performing interference mitigation. - View Dependent Claims (18, 19, 20, 21)
