The Future of Wireless

Multimedia Broadcast and Multicast Services,

(MBMS), introduced for WCDMA in Release 6, supports multicast/broadcast ser-

vices in a cellular system, thereby combining multicast and unicast transmissions

within a single network

MIMO is one of the major new features in Release 7, introduced to increase the

peak data rates through multi-stream transmission Strictly speaking, MIMO, Mul-

tiple Input Multiple Output, in its general interpretation denotes the use of multiple

antennas at both transmitter and receiver

MIMO, or spatial multiplexing, should mainly be seen as a tool to improve the end-

user throughput by acting as a ‘data-rate booster’
