Configuration of carrier-related reference signal transmission

A method comprising:

• determining a transmission mode for reference signal transmission on a carrier from a base station or access node of a communication system out of at least a long-cycle discontinuous transmission mode and a short-cycle discontinuous transmission mode, wherein the transmission mode is determined on the basis of at least one of an activation state of the carrier as serving cell and/or secondary cell and/or measurement object cell and a period of radio resource management measurement on the carrier, and
• setting the determined transmission mode as a reception mode for reference signal reception on the carrier.

An apparatus comprising:

• an interface configured to communicate with at least another apparatus, a memory configured to store computer program code, and a processor, wherein the memory and the computer code are configured with the processor to cause the apparatus to perform:
• setting a transmission mode for reference signal transmission on a carrier out of at least a long-cycle discontinuous transmission mode and a short-cycle discontinuous transmission mode, wherein the transmission mode is set on the basis of at least one of an activation state of the carrier as serving cell and/or secondary cell and/or measurement object cell and a period of radio resource management measurement on the carrier, and
• configuring transmission of at least one reference signal on the carrier according to the set transmission mode.
