This paper reviews basics of radio planning for 3GPP LTE. Both coverage-limited and interference-limited scenarios are considered. For the coverage-limited scenario LTE link budget is compared to that of 3GPP Release 8 HSPA+ with 2x2 MIMO. It is shown that, given the same 5MHz bandwidth, both systems have similar cell ranges but, for a given target bit rate, there exists an optimum LTE system bandwidth that maximizes cell range in both
uplink and downlink. For the interference-limited scenario (with random uncoordinated interference) we illustrate the relationship between average network load, cell edge target throughput and cell range, as well as the notion of interference margin for cell range dimensioning. Impact of base station antenna configurations on dual-stream Multiple-Input Multiple-Output (MIMO) performance is demonstrated by means of a real-world measurement
example. The impact of advanced LTE radio resource management features are briefly reviewed. Finally, the most important radio parameter planning tasks are introduced.
