User equipment feedback its current serving cells and neighbor cells’ RSRP via measurement report. Analyzing those report data

we can be aware of its serving cells’ downlink coverage

as well as its neighbor cells’ too

if we consider the neighbor cells’ RSRP. Here bring out a two-dimension diagram

serving-cell dimension and neighbor-cell dimension

with several zones divided according to their handover strategy. This diagram is able to describe TD-LTE coverage intuitively

comprehensively

scientifically. We offer network optimization engineers a tool to discover coverage problems

such as the coverage holes

overlapping

neighbor missing.
