Air interface dimensioning techniques for coverage and capacity-limited HSPA based networks

Improved Multiple-Scenario Radio Network Dimensioning for WCDMA

“…A loaded macro cell is typically limited by the available UL capacity of the cell; in particular, the UL interference capacity limit. The cell size will shrink when there are more users in the cell, as given by Equations (1) and (4). For UL capacity limited cases, the maximum cell capacity is limited by the maximum desired UL load, In summary, the nature of the network can be characterized into different conditions as follows: UL capacity limited:…”

“…Many of these challenges are related to the time-consuming design and planning of multi-service radio networks, and some to the particular aspects of the underlying WCDMA radio access method [1]. Initial dimensioning is conventionally accomplished in an iterative process to fulfil the target coverage and capacity objectives [1][2][3][4]. This is both complicated and time consuming especially when all characteristics of the radio interface are to be considered.…”

“…To date, different methodologies to simplify network dimensioning through modeling and optimization by mathematical and heuristic algorithms have been proposed [1][2][3][4]. The work in [1] and [2] adopted a mathematical approach where modeling of multi-service environments is described and implications on system performance are addressed.…”

“…In [3], a method for dimensioning WCDMA networks with variable loads is presented, where iterations take place for each clutter type, area and subscriber input. In [4], characterization of coverage and capacity limited high-speed packet access networks is made. In [5], the authors proposed algorithms for joint uplink/downlink Universal Mobile Telecommunications System radio planning with the objective of minimizing total power consumption in the network.…”
