An air interface dimensioning campaign consists of numerous successive steps in the link budget calculation, which in turn is based on a set of input parameters that can be categorized/grouped as follows: General parameters - define possible center frequencies (operating bands), channel bandwidths, clutter types, simulation cases, etc. Equipment parameters - provide equipment specifications, antenna configurations, gains and losses etc. Radio propagation parameters - consist of parameters which describe wave propagation in a specific radio environment, for example channel models, mobility, etc. Capacity dimensioning - parameters of this group are necessary in E-UTRAN for a correct definition of power and resource sharing among users. Interferences - represents the group of parameters related to interference calculation for example cell loads, G-factor, etc. Radio propagation prediction - represents the group of parameters related to propagation models for example intercept points, propagation model slopes, eNodeB antenna and UE heights Radio Network Configuration - represents the group of parameters that specify cell layout and sectorization The output of an air interface dimensioning campaign is the following: Maximum Allowable Path Loss Cell ranges based on propagation models' formulas Site-to-Site distance and site areas for different site layouts, which finally yields an estimation of the number of sites and site density required to cover the given area.

LTE radio planning involves a number of steps such as dimensioning, planning tool setup, nominal plan creation and site survey. The process is similar in any wireless network. Slide shows the general planning process for mobile LTE. What differentiates LTE from other technologies are the parameters, PIs, KPIs. Coverage and capacity planning have some LTE-specific items but generally it is quite similar to HSPA planning. Both LTE and UMTS/HSPA use similar services, coverage targets, similar mobility algorithms, and similar performance specifications. The main emphasis is to ensure good enough SINR in the network area along with good coverage measured either by RSSI or as per 3GPP [TS36.214] by Reference Signal Received Power (RSRP)

Nominal planning • •
•
Create a nominal plan Typical actions: – Propagation model tuning – Nominal coverage planning with planning tool Based on coverage thresholds: RSRP & CINR – Capacity analysis – Site surveys – Site pre-validation (*) still open what will be the LiBu thresholds used. Atoll uses wideband received power but it is possible to convert it to RSRP.
Link budget & capacity dimensioning
Define thresholds from LiBu (*)
Create detailed network plan (cells, antennas, carriers) using LiBu thresholds
Perform capacity analysis to check network capacity against more detailed traffic estimates
RSRP: Reference Signal Received Power CINR: Carrier to Interference + Noise Ratio LiBu: Link Budget

LTE Detailed Radio Planning Process

RA41201EN160GLA0

The aim of radio planning is to define a set of site locations and their respective configurations that addresses the coverage and capacity requirements derived from the dimensioning. The radio planning task is based on the outputs from the dimensioning, especially the calculated site densities in each clutter type. Network planning works with a high level of detail. The site count derived from radio planning can sometimes be significantly different from the site count derived from dimensioning since the actual site coverage may differ significantly from the assumed empirical model(s) along with network and earth surface irregularities. There is always a risk that the planned site count may exceed the estimated site count from dimensioning. As a result, several planning iterations are needed to reach a reliable figure as per clutter and design requirements.
