3GPP defines minimum RF performance requirements for terminals (UE) and for base stations (eNodeB). These performance requirements are an essential part of the LTE standard as they facilitate a consistent and predictable system performance in a multi-vendor environment. The relevant specifications are [1–3] covering both duplex modes of LTE: frequency division duplex (FDD) and time division duplex (TDD).
Some of the RF performance requirements, for example limits for unwanted emissions, facilitate the mutual co-existence of LTE with adjacent LTE systems or adjacent 2G/3G systems run by different operators without coordination. The corresponding requirements may have been derived from either regulatory requirements or from co-existence studies within 3GPP—see .
Other performance requirements, for example modulation accuracy and baseband demodulation performance requirements, provide the operator assurance of sufficient performance within his deployed LTE carrier.
 is the basis for the eNodeB test specification , which defines the necessary tests for type approval. Correspondingly,  is the basis on the UE side for the test specifications  and .
