Multimedia Broadcast/Multicast Services (MBMS), introduced in Universal Mobile Telecommunication System (UMTS), have the
aim to allow transmissions from a single source entity to multiple destinations. From the radio perspective, MBMS foresees both pointto-
point (PtP) and point-to-multipoint (PtM) transmission mode, supported by Dedicated, Common, and Shared channels. The High
Speed Downlink Packet Access (HSDPA), analyzed in this paper, can guarantee a higher data rate through the introduction of High
Speed Downlink Shared Channel (HS-DSCH), thus improving the performance of MBMS transmissions. The aim of this paper is to
investigate the impact of the User Equipment (UE) speed on the maximum number of users that the HS-DSCH can support for MBMS
applications. In particular, two different mobility profiles are taken into account (Pedestrian and Vehicular) and the obtained results
are validated by considering different transmission power levels, cell coverage sizes and bit rates. |
