TECHNIQUE FOR OPERATING A NETWORK NODE IN A HETEROGENEOUSLY DEPLOYED NETWORK

摘要

A technique for operating a network node in a heterogeneously deployed network comprising network nodes of different nominal transmit powers and at least partially overlapping coverage areas is described. A method implementation of this technique comprises a step of operating the network node in a base mode in which the network node is configured to transmit terminal-specific demodulation reference signals for a first set of terminal devices. The method comprises the further step of selectively activating or deactivating operation of the network node in a Single Frequency Network (SFN) mode in which the network node is configured to transmit, for a second set of terminal devices, the same cell-specific reference nodes as another network node of the heterogeneously deployed network that has a larger nominal transmit power.

1: A method of operating a network node in a heterogeneously deployed network comprising network nodes of different nominal transmit powers and at least partially overlapping coverage areas, the method comprising:
operating the network node in a base mode in which the network node is configured to transmit terminal-specific demodulation reference signals; wherein the terminal-specific demodulation reference signals are transmitted for a first set of terminal devices; and the method further comprises selectively activating or deactivating operation of the network node in a Single Frequency Network (SFN) mode in which the network node is configured to transmit, for a second set of terminal devices, the same cell-specific reference signals as another network node of the heterogeneously deployed network that has a larger nominal transmit power.
