14.1 Introduction

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 [4].

Other performance requirements, for example modulation accuracy and baseband demodulation performance requirements, provide the operator assurance of sufficient performance within his deployed LTE carrier.

[2] is the basis for the eNodeB test specification [5], which defines the necessary tests for type approval. Correspondingly, [1] is the basis on the UE side for the test specifications [6] and [7].

This chapter presents the most important LTE minimum performance requirements, the rationale underlying these requirements and the implications ...
