scope:

The present document intends to identify use cases and provide system level functionality for building and exploiting evolutionary Radio Environment Maps (REMs) in a single or multi-RAT context in intra-operator scenarios.

Building the REM within an RRS context requires the enhancement of existing network entities, protocols and interfaces accomplishing the tasks of requesting, storing and processing geo-located measurements related to the radio environment.

It is expected that REMs will be exploited in an RRS context for network troubleshooting and radio resource management optimization. The present document includes a general description of the use cases and associated stakeholders as well as information flows and high level requirements. Technical challenges are also identified.
