“…for the uplink and downlink, the gain is around 2.0 dB, when the path loss from UE to two different Nodes B is equal). However, measurements with real equipment show an average gain of 0.5 dB when power control commands are combined and, surprisingly, loss of around of 1.9 dB have been measured when power commands are not combined [1, p. 234], [9]. In this contribution, we shall adopt a neutral approach considering a net gain of 0.0 dB.…”

It is developed a study of case, unifying theoretical and practical aspects, regarding the cell-planning of a third generation (3G) network that implements a radio interface based on the Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access (UTRA) Wideband Code division Multiplexing (WCDMA) Frequency Division Duplexing (FDD) technology. The used methodology is validated by the close agreement between the measured and estimated cell coverage.

“…In [4] different strategies of power control in a UMTS system are applied to a user in SHO. In [5], [6] soft handover gain and capacity increase are investigated because of using SHO in uplink direction. In [7], [8] the effect of the SHO on the WCDMA system in the forward direction is discussed, considering capacity and outage probability.…”

Power control and soft handover are two important technologies in radio resource management that ensure the capacity and performance of a DS-CDMA system. Using these technologies along with Rake Receiver and error correction coding for interference limited DS-CDMA systems results in reducing interference while increasing capacity and coverage. In this paper, the performance of power controlled uplink under soft handover in DS-CDMA systems which uses error correction coding, has been evaluated. Then the performance improvement due to macro selection diversity has been calculated. It is shown that system under soft handover has less sensitivity against incrementing the power control error (PCE) and number of users.Finally it is pointed out that by using convolutional error correction coding scheme an additional gain is obtained.2008 ISECS International Colloquium on Computing, Communication, Control, and Management 978-0-7695-3290-5/08 $25.00
