  • Introduction

    1MA195_3e Rohde & Schwarz LTE-A BaseStation Rx Tests 4

    1 Introduction

    Long Term Evolution (LTE) networks or Evolved Universal Terrestrial Radio Access (E-

    UTRA) (from Releases 8 and 9) have long since been introduced into daily usage. As a

    next step, 3GPP has added several extensions in Release 12, known as LTE-

    Advanced (LTE-A). These include a contiguous and non-contiguous multicarrier and/or

    carrier aggregation (CA) option and changes to MIMO (up to 8x8 in the downlink and

    introduction of MIMO in the uplink).

    An overview of the technology behind LTE and LTE-Advanced is provided in

    Application Note 1MA111, 1MA232 and 1MA252.

    The LTE-A conformance tests for base stations (eNodeB) are defined in 3GPP TS

    36.141 Release 12 [1] and include transmitter (Tx), receiver (Rx) and performance (Px)

    tests. T&M instruments from Rohde & Schwarz can be used to perform all tests easily

    and conveniently.

    This application note describes the receiver (Rx) tests in line with TS36.141 Chapter 7.

    It explains the necessary steps in manual operation for vector signal generators and

    spectrum analyzers. A free remote-operation software program is additionally provided.

    With this software, users can remotely control and demo tests on base stations quickly

    and easily. It also provides the SCPI commands required to implement each test in

    user-defined test programs.

    The transmitter (Tx) tests (TS36.141 Chapter 6) are described in Application Note

    1MA154 and the performance (Px) tests (TS36.141 Chapter 8) are covered in

    Application Note 1MA162.
