Nodes and methods for allocating reference signal parameters to user equipments

A method performed by a scheduling node for allocating Demodulation Reference Signal, DMRS, parameters to at least one User Equipment, UE, of the scheduling node, the method comprising:

• receiving, from a Resource Partitioning Node, RPN, a partition of at least one type of DMRS parameters to be used by the at least one UE for configuring DMRSs;
• and
• signaling to the at least one UE, a DMRS configuration associated with the received partition of the at least one type of DMRS parameters to be used for configuring DMRSs.

A Resource Partitioning Node, RPN, associated with at least a first and a second scheduling node configured to allocate Demodulation Reference Signal, DMRS, parameters to at least one User Equipment, UE, of the first scheduling node and to at least one UE of the second scheduling node, the RPN comprising:

• an assigning unit configured to assign a first partition of at least one type of DMRS parameters to the at least one UE of the first scheduling node and a second partition of the same type of DMRS parameters to the at least one UE of the second scheduling node;
• and
• a signaling unit configured to signal, to the first and the second scheduling node, the respective partition of the at least one type of DMRS parameter to be used by the respective at least one UE.

A scheduling node configured to allocate Demodulation Reference Signal, DMRS, parameters to at least one User Equipment, UE, of the scheduling node, the scheduling node comprising:

• a receiving unit configured to receive, from a Resource Partitioning Node, RPN, a partition of at least one type of DMRS parameters to be used by the at least one UE for configuring DMRSs;
• and
• a signaling unit configured to signal, to the at least one UE, a DMRS configuration associated with the received partition of the at least one type of DMRS parameters to be used for configuring DMRSs.

A computer program product, storing computer readable code, which when run in a processing unit comprised in an arrangement in a Resource Partitioning Node associated with at least a first and a second scheduling node for allocating Demodulation Reference Signal, DMRS, parameters to at least one User Equipment, UE, of the first scheduling node and to at least one UE of the second scheduling node, causes the Resource Partitioning Node to perform a method, the method comprising:

• assigning a first partition of at least one type of DMRS parameters to the at least one UE of the first scheduling node and a second partition of the same type of DMRS parameters to the at least one UE of the second scheduling node;
• and
• signaling, to the first and the second scheduling node, the respective partition of the at least one type of DMRS parameter to be used by the respective at least one UE.
