Adapting to signal loss in a fronthaul link based on a reference metric

A signal loss adjuster for adapting to signal loss in a fronthaul link between a baseband node and a radio node of a radio access network, the signal loss adjuster comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the signal loss adjuster to:
• obtain a loss metric, the loss metric indicating loss of pilot signals over the fronthaul link in a measurement interval;
• obtain a reference metric, based on the loss metric, the reference metric indicating expected impact on at least one reception quality indicator in a receiver based on the loss of pilot signals;
• obtain a reception quality indicator, indicating quality of reception over radio of the pilot signals;
• and
• adapt a result from the reception quality indicator based on the reference metric.

A computer program product comprising:

• a computer program for adapting to signal loss in a fronthaul link between a baseband node and a radio node of a radio access network, the computer program comprising computer program code which, when executed on a signal loss adjuster causes the signal loss adjuster to:
• obtain a loss metric, the loss metric indicating loss of pilot signals over the fronthaul link in a measurement interval;
• obtain a reference metric, based on the loss metric, the reference metric indicating expected impact on at least one reception quality indicator in a receiver based on the loss of pilot signals;
• obtain a reception quality indicator, indicating quality of reception over radio of the pilot signals;
• and
• adapt a result from the reception quality indicator based on the reference metric;
• and
• a computer readable means comprising non-transitory memory in which the computer program is stored.
