LTE-A HetNet LTE A uses network densification/hetnet (a network of cells of different sizes) to enhance system capacity One consequence of network densification is increased interference LTE-A offers many complex and advanced mechanisms (e.g., ICIC, eicic, FeICIC, NAICS, and advanced receivers) to handle this interference 17
HetNet lab testing How to test such function in chipset? Macro and micro need to sync up Massive amount of cables and infra 18

Scenarios in the LTE-A World Lets take a LTE-A scenario, with 8 enbs, each with CA and the device moving through this environment Testing this scenario requires changing: Power (or path loss) Noise Interference Doppler Power delay profile Correlation Propagation delay This has to be done 8 times (for each sector), for every device (across links) at the desired resolution Creating these test scenarios manually is NOT a viable option 23
Scenario Builder Scenario Builder is a powerful wizard to create the complex scenarios needed for LTE-A, HetNet Drag, drop and design that allows creation of complex scenarios Seamless, automatic computation of RF environment (power, channel conditions, etc.) for the defined scenario Automatic configuration of the RNX test bed to map to the scenario at hand 24
Scenario Builder Enables Creation of Complex Scenarios Scenario Builder is a powerful wizard to create the complex scenarios needed for LTE-A, HetNet Drag, drop and design that allows creation of complex scenarios Seamless, automatic computation of RF environment (power, channel conditions, etc.) for the defined scenario Automatic configuration of the RNX test bed to map to the scenario at hand Scenario builder library for commonly used scenarios: 3GPP carrier aggregation scenarios Operator deployment scenarios 25
Scenario Builder UI Location and coverage area of the cell Controls to manage the canvas Different types of devices you can drop on the canvas User can drag this slider to determine route of mobility path A waypoint indicates a point in the mobility path. User can choose channel conditions at the beginning of waypoint Properties associated with an ENB or a waypoint 26

FTL Intro Field testing has some inherent challenges Time consuming Expensive Results are not repeatable since the real world is dynamic R&D may not be local to where you see the issue 29
The Solution - Field-to-Lab! FTL is a solution that recreates the RF environment from the Field, in the Lab 30
How Does FTL Work? FTL Drive log from RF Scanne r/dm AzMapper AzPlayer ACE Platform Device in the Lab Support for popular platforms such as: Qualcomm QXDM JDSU W1314A PCTEL SeeGull Accuver XCAL Anite Nemo Huawei PROBE Intelligently postprocesses drive log data to remove erroneous data Provides L1/L2/L3 visualization capabilities to help narrow down problem areas Generates playback files to be used with AzPlayer Streams RF channel information to the ACE MX Recreates the complex RF environment captured in the drive log Creates a repeatable RF environment. Device subject to field conditions FTL also allows user to subject device to variants of the field condition by modifying aspects of the environment 31
