HANDLING OF OPERATIONAL METRICS IN RESOURCE-LIMITED DEVICES AND COMMUNICATION SYSTEMS
Some aspects of the inventive concept relate to techniques that can be used for managing operational metrics in resource-limited devices. These techniques can include obtaining multiple measurements of an operational metric over time, with each measurement falling within a predetermined overall range. The measurements can be aggregated into predefined data bins, each corresponding to a specific sub-range. A count can be determined for each data bin, generating distribution data that represents the distribution of the metric over time. The distribution data can be encoded into a communication message by mapping it to specific positions within the message, according to a predefined mapping policy. This allows the distribution of the operational metric to be determined based on the received message and the mapping policy.
