Abstract

This paper proposes a novel mechanism for efficient power
control during multicast transmissions in Beyond 3rd Generation
(B3G) mobile networks. The mechanism utilizes optimally the
available power resources of Universal Mobile
Telecommunication System (UMTS) base stations, resulting to
network capacity maximization. The proposed mechanism is
based on the concept of transport channels combination (point-topoint
and/or point-to-multipoint radio bearers) in any cell/sector
of the network in which Multimedia Broadcast/Multicast Service
(MBMS) users are residing. In particular, the transport channel
combination that minimizes the transmission power of the base
station is selected for the transmission of the MBMS traffic to the
corresponding cell. The mechanism is evaluated through several
realistic scenarios and the results indicate the ability of the
mechanism to utilize optimally the radio resources of the network.
Furthermore, our approach is compared with several power
control mechanisms existing in the bibliography, including the 3rd
Generation Partnership Project (3GPP) approaches (presented in
3GPP TS 25.346 and 3GPP TR 25.922), in order to highlight the
enhancements that it provides
