1. A network node configured to communicate with a wireless device, the network node comprising:
processing circuitry configured to:
trigger a first aperiodic, AP, reference signal transmission using a reference signal trigger state; and
trigger a second AP reference signal transmission using the reference signal trigger state associated with the first AP reference signal transmission, the second AP reference signal transmission being configured to use at least one different frequency resource than the first AP reference signal transmission, the second AP reference signal transmission being configured to start at a different frequency resource than a start of the first AP reference signal transmission, the second AP reference signal transmission being configured to use frequency resources that are contiguous with frequency resources used for the first AP reference signal transmission; the second AP reference signal transmission being configured to use at least one frequency resource that is used by the first AP reference signal transmission.
