Dynamic cell clustering for coordinated multipoint operation

An apparatus for controlling an own cell comprising:

• at least one processor;
• and
• at least one memory including computer program code;
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
• receive clustering metric information defining relevant metrics for making cell clustering decision for coordinated multipoint operation from a network element serving a neighboring cell, wherein the clustering metric information comprises a number or fraction of cell-edge coordinated multipoint enabled user equipments in the neighboring cell that consider the own cell as one of its top M interferers, where M>=1;
• and
• decide, based on the received clustering metric information, whether to include the neighboring cell to a cluster for coordinated multipoint operation.

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code;
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
• compose clustering metric information defining relevant metrics for making cell clustering decision for coordinated multipoint operation involving an own cell, wherein the clustering metric information comprises a number or fraction of cell-edge coordinated multipoint enabled user equipments in the neighboring cell that consider the own cell as one of its top M interferers, where M>=1;
• and
• cause transmission of the clustering metric information to a network element of a neighboring cell.
