Abstract
Disclosed is a method and performed by a system of a wireless communication network for determining signal quality indications. The method includes determining a correlation between a quality of a signal received at a first wireless device and a quality of a signal received at a second wireless device, obtaining a first indication of quality of a signal received at the first wireless device, and determining a second indication of quality of signals received at the second wireless device based on the first indication and the determined correlation. The system may be implemented in a radio access network node.

A method performed by a system of a wireless communication network for determining signal quality indications, the method comprising:
- determining a correlation between a quality of a signal received at a first wireless device and a quality of a signal received at a second wireless device;
- obtaining a first indication of quality of a signal received at the first wireless device;
- determining a second indication of quality of signals received at the second wireless device based on the first indication and the determined correlation;
- and
- triggering sending, based on the determined correlation, one of:
- an instruction to at least one of the first wireless device and the second wireless device to send indications of quality of signals to a radio access network node less often than before the correlation was determined;
- and
- requests to at least one of the first wireless device and the second wireless device for indications of quality of signals, the requests being sent less often than before the correlation was determined.
A system operable in a wireless communication system for determining signal quality indications, the system comprising a processing circuitry and a memory, the memory containing instructions executable by the processing circuitry to cause the system to:
- determine a correlation between a quality of a signal received at a first wireless device and a quality of a signal received at a second wireless device;
- obtain a first indication of quality of a signal received at the first wireless device;
- and
- determine a second indication of quality of signals received at the second wireless device based on the first indication and the determined correlation;
- trigger sending, to the second wireless device, signals one of modulated and coded based on the determined second indication of signal quality;
- receive, from the second wireless device, an indication of change in performance at the second wireless device based on the sent signals one of modulated and coded using the determined second indication;
- and
- update the determined correlation based on the received indication of performance change.
A non-transitory computer storage medium storing a computer program comprising instructions, which, when executed by at least one processing circuitry of a system of a wireless communication network, configured for determining signal quality indications, causes the system to:
- determine a correlation between a quality of a signal received at a first wireless device and a quality of a signal received at a second wireless device;
- obtain a first indication of quality of a signal received at the first wireless device;
- and
- determine a second indication of quality of signals received at the second wireless device based on the first indication and the determined correlation;
- and
- trigger sending, based on the determined correlation, one of:
- an instruction to at least one of the first wireless device and the second wireless device to send indications of quality of signals to a radio access network node less often than before the correlation was determined;
- and
- requests to at least one of the first wireless device and the second wireless device for indications of quality of signals, the requests being sent less often than before the correlation was determined.
