LTE Coverage Design and Performance Verification TSB–88 For Public Safety LTE

Key Attributes of the Proposed LTE Coverage Design Procedure Follow the well established TSB–88 definitions and procedures; however, using the LTE DRCPC Data Rate Channel Performance Criterion (DRCPC) is the LTE coverage design criterion. DRCPC is the minimum data rate required to meet the coverage design goal for a given application The coverage design is done at a specific traffic load level Interference depends on the LTE traffic load; therefore, coverage depends on the traffic load. How about OOB IF? Limit TSB – 88 update to LTE coverage design and verification for initial release

LTE Coverage Example The DRCPC for this example is 500 kbps inbound and 1000 kbps outbound The coverage boundaries are determined by the DRCPC For performance verification, the data rate is measured throughout the service area Measured data rate in a given geographic tile is compared to the DRCPC

Key Attributes of the Proposed LTE Verification Procedure The primary verification criterion is measured data rate using The verification procedure must provide a method to configure the traffic load to emulate the design traffic load Downlink only? Follow the well established TSB–88 definitions and procedures for measuring service area or covered area reliability Define a grid of test tiles Measure data rate in each tile and compare the measured data rate to the design DRCPC. Need details on time averaging, etc. Calculate the measured reliability as the ratio of test tiles with measured data rate greater than the DRCPC to the total number of test tiles Limit TSB – 88 update to LTE coverage design and verification for initial release
