|IST B-BONE: Broadcasting
and Multicasting over Enhanced UMTS Mobile Broadband Networks
|The objectives of
the B-BONE project are to:
- Characterize the requirements
of broadcasting services, namely TV, radio and data broadcast and the
dynamic adaptation of the information to the terminal capabilities.
- Evaluate the most suitable
frequency bands already allocated for IMT-2000 and those that may also
become available in the future after WRC decisions (e.g. broadcasting
systems spectrum) in accordance to the expected traffic model.
- Define and characterize
specific reference scenarios for the delivery of digital broadcast/multicast
and multimedia services.
- Define a multi-carrier (MC
DS-WCDMA) system, with combined use of multiple antennas at both the
transmitter and receiver (although with strong limitations) to enhance
the capacity required to provide more than 4 Mbps everywhere, and up
to 32Mbps for terminals near to the base station (derived by the DVB-T
- Enhance UMTS FDD and TDD
modes with multi-carrier and MIMO techniques to carry digital broadcast
services, and study the impact of vertical handover.
- Define adaptive transmission
techniques for network resources allocation so as to take advantage
of favourable channel conditions by transmitting at high data rates,
while reducing data rates
in bad channel conditions.

OVER ENHANCED UMTS MOBILE BROADBAND NETWORKS
Project website (external link)
- Develop and implement Resource
Management algorithms enabling QoS provisioning and service differentiation
for IP-based RAN and Core networks supporting broadcast, multicast and
- Investigate techniques for
seamless integration of broadcast, multicast and unicast transmissions
in all-IP combined wired and wireless networks.
- Evaluate the effects of
Soft Handover and Hard Handover due to user mobility in broadcasting/multicasting
over broadband cellular networks.
- Develop mechanisms for the
aggregation of individual resource requests for the same broadcaster
- Develop auction based resource
allocation schemes for aggregate requests and mechanisms for cost splitting
between the multiple participants in broadcasting/multicasting type
- Build a link and system
level simulator for the all-IP radio access and core networks of the
proposed Enhanced UMTS network.
and publish an electronic library of combined MC DS-WCDMA with MIMO
systems for capacity enhancement of UMTS and resource management algorithms
for effective provision of broadcast/multicast multimedia services.
There are four key issues addressed
in the B-BONE project:
- The first issue deals
with the identification of system requirements for digital broadcasting/multicasting
services over the Enhanced UMTS cellular network, dynamic adaptation
of the contents to terminal capabilities and the required spectrum.
- The second issue deals
with the wireless techniques required to increase the bit rate and
the throughput, namely, multi-carrier, MIMO systems and adaptive
- The third issue deals
with the optimisation and management of radio and network resources
in RAN and Core networks that are broadcast/multicast capable.
- Finally, the fourth
issue deals with system level simulation given the proper models.
This will enable not only the evaluation of the
capacity gain, but also of the feasibility of the project proposed
