Key facts

  • 5G uplink/downlink FDD or TDD signals in line with 3GPP Release 15  and Release 16
  • All numerologies and channel bandwidths for FR1 and FR2
  • Channel coding and PDSCH/PUSCH spatial multiplexing
  • Test case wizard for easy test setup in line with 3GPP TS 38.141-1 and 38.141-2
  • Logging of intermediate results from the signal generation chain

5G new radio signal generation

The 5G NR software option simplifies the uplink and downlink of 5G NR signal configurations. It supports all of the waveforms, channel bandwidths, modulation schemes and numerology options specified in the standards. The intuitive GUI allows many parameters (multiple bandwidth parts or MIMO precoding) to be configured directly on the instrument or desktop using WinIQSIM2.
Context-sensitive help menu, presets for downlink test models, uplink FRCs and a graphical timeplan of the configured signals all contribute to a fast and efficient workflow. Intermediate signal generation chain results can be easily logged for debugging. A test case wizard helps wih the easy set up of BS tests.

 

Features & benefits

Supports all physical signals and channels

Flexibly configure 5G new radio physical layer

The 5G NR software options implement the physical layer in line with 3GPP Release 15 and 16. It supports all downlink and uplink physical channels, multiple bandwidth parts with mixed numerology  and important physical layer features such as channel coding, scrambling, multiplexing of data and control information. The option provides standard-conformant signals to test components, modules, receivers and base stations.

MIMO, carrier aggregation (CA) and multiple users

Easily configure MIMO signals and up to 16 component carriers for CA

The 5G NR software options provide full spatial multiplexing (MIMO) and transmit diversity support with flexible antenna port mapping. The intracarrier and intercarrier aggregation of up to 16 component carriers can be configured, including cross-carrier scheduling.
Up to 10 scheduled users can be configured for realistic receiver tests.

Test case wizard for easy setup of BS tests

The test case wizard supports the configuration of test signals in line with 3GPP TS 38.141-1 as required for base station conformance tests. It offers a selection of predefined settings for wanted and interfering signals according to defined test cases. The closed-loop BS test option also enables dynamically changing 5G NR uplink test signals needed to perform HARQ feedback tests as described in Chapter 8.

Simplified physical layer configuration

The "Quick Settings" menu simplifies the generation of 5G NR signals for component testing. Important parameters such as channel bandwidth, subcarrier spacing, modulation and resource block allocation can be changed with a simple click. The TDD slot allocation including a  special slot can be configured with a graphical display.

Accurate level setting and crest factor reduction

The flexibility of the 5G NR physical layer in frequency and time domains can make the setting of a certain output power challenging. Different modes are available to define the method for calcualting the signal power. This allows accurate PRACH measurements as the reference bandwidth is automatically configured.  Signals with a certain target crest factor can be directly configured (requires CFR option).

Supports design flow optimization

Log files for design verification and enhanced debugging

Logging points are provided to capture  intermediate results from the signal processing chain (including forward error correction) which can be stored as bit stream or I/Q sample files. This enables designers to verify their own receiver and transmitter software implementations of the 5G NR physical layer and obtain insights into enhanced debugging.
