1. TSB–88 For Public Safety LTE

2.  Proposal: release documents in phases ◦ First release:  Basic LTE coverage modeling and verification concepts such as tile reliability, service area reliability, data rate channel performance criterion, etc.  High-level overview of additional key LTE concepts  Significant benefit in defining these basic coverage modeling and verification concepts  e.g. industry conversations have revolved around questions like “what is LTE coverage”, “what do you measure to validate LTE coverage”, etc.  Focusing on key concepts will accelerate document development and delivery 2

3.  Front matter ◦ Forward, introduction, scope statement, and references  Definitions and abbreviations ◦ Key LTE coverage modeling definitions such as Data Rate Channel Performance Criterion (DRCPC), Tile Reliability, Covered Area Reliability, Service Area Reliability, etc. 3

4.  LTE Technical Performance Definitions and Criteria ◦ Scope for First Document Release  Service Area  Data Rate Channel Performance Criterion (DRCPC)  Contour Reliability  Tile Reliability  Tile-Based Area Reliability  Subscriber Distribution  Traffic Models and Loading  Need to relate model load to field validation load  Resource Block Sharing 4

5.  Front Matter ◦ Forward, introduction, scope statement, and references  Definitions and abbreviations ◦ Key LTE coverage verification definitions such as Data Rate Channel Performance Criterion (DRCPC), Number of Test Tiles, Tile-based Area Reliability, Validated Service Area Reliability, etc. 5

6.  Performance Confirmation ◦ Validated Service/Covered Area Reliability ◦ Determination of Number of Test Tiles (Outdoor Only) ◦ Estimate of Proportions ◦ Pass/Fail Test Criteria  The “Greater Than” Test  The “Acceptance Window” Test ◦ Confidence Level ◦ Confidence Interval 6

7.  Size Constraints & Accessibility ◦ Outdoor ◦ Tunnel ◦ Indoor ◦ Accessibility  Treating Anomalous Tiles  In-Building Recommendations  LTE Coverage Acceptance Testing ◦ Traffic Load Emulation Procedures ◦ Data Rate Measurement Procedures 7
