I use it with Qualcomm QXDM and QPST tools to analyse wireless protocol stack messages. Qualcomm Diag is the qualcomm diagnostics interface built into many Qualcomm based chipsets or rather their software for a long time more than a decade. Feature Group Indicators (FGI bits) in LTE Rel. The prevalence of Snapdragon Processor-based apparatus is rising day by day.LTE eNodeB Schedulers and Different Scheduling Types.Hybrid Automatic Repeat Request (HARQ) in LTE FDD.LTE Channels: Logical, Transport and Physical Channels Details and Mapping.Signaling Radio Bearer Configurations (SRBs)Ĭontrol Information (CQI/RI/PMI/HARQ) for Uplink over PUCCH:īuffer Status Report (BSR) and Power Head Room (PHR): Initial Access logs are related to cell search procedure, it shows results related PSS, SSS and frequency scan to get Physical Cell ID (PCI). In this post, we tried to put some of very import Logs packets information to help Wireless Test Engineers, how they can make best use of QXDM to debug any issue.

Whether it is Field testing or Lab testing, initial product development or carrier acceptance QXDM is most accepted tool. It is not publicly documented, but there are tools from Qualcomm (QPST, QXDM) as well as proprietary third-party tools and some Free Softare projects that implement parts of it.

QXDM is most widely used tool in wireless 4G,5G technology to capture Qualcomm based Mobile signalling and data details logs for debugging purpose.
