Abstract
A method for receiving a PDCH is provided. The method comprises: receiving, by a UE, information identifying a plurality of resource elements that are transmitted with zero power in a resource block containing the PDCH; receiving, by the UE, a first DMRS on a first DMRS port transmitted from a first cell; and receiving, by the UE, the PDCH that is transmitted on the first DMRS port.
Claims38
A method for receiving a physical downlink channel (PDCH), the method comprising:
- receiving, by a user equipment (UE), from a first cell, information identifying a first plurality of resource elements that are transmitted with zero power in a resource block including the PDCH, wherein the first plurality of resource elements occupy a subset of resource elements used for transmission of a first demodulation reference signal (DMRS) associated with a second cell;
- receiving, by the UE, a second DMRS in a second plurality of resource elements on a DMRS port associated with the first cell;
- and
- receiving, by the UE, the PDCH that is transmitted on the DMRS port.
A method for transmitting a physical downlink channel (PDCH), the method comprising:
- transmitting, by a network element, information identifying a first plurality of resource elements that are transmitted with zero power in a resource block including the PDCH from a first cell, wherein the first plurality of resource elements occupy a subset of resource elements used for transmission of a first demodulation reference signal (DMRS) associated with a second cell;
- transmitting, by the network element, a second DMRS in a second plurality of resource elements on a DMRS port associated with the first cell;
- and
- transmitting, by the network element, the PDCH on the DMRS port.
A user equipment (UE) comprising:
- a processor configured such that the UE receives, from a first cell, information identifying a first plurality of resource elements that are transmitted with zero power in a resource block including the PDCH, wherein the first plurality of resource elements occupy a subset of resource elements used for transmission of a first demodulation reference signal (DMRS) associated with a second cell, further configured such that the UE receives a second DMRS in a second plurality of resource elements on a DMRS port associated with the first cell, and further configured such that the UE receives a physical downlink channel (PDCH) that is transmitted on the DMRS port.
A network element comprising:
- a processor configured such that the network element transmits information identifying a first plurality of resource elements that are transmitted with zero power in a resource block including the PDCH from a first cell, wherein the first plurality of resource elements occupy a subset of resource elements used for transmission of a first demodulation reference signal (DMRS) associated with a second cell, further configured such that the network element transmits a second DMRS in a second plurality of resource elements on a DMRS port associated with the first cell, and further configured such that the network element transmits a physical downlink channel (PDCH) on the first DMRS port.
