Project Groups

• Wide Area Coverage with High Mobility Access Systems for 4G– Centralized systems with high mobility, lower data

rates and wider coverage areas• Pervasive Wireless Access for 4G

– Decentralized systems with low mobility, higher data rates and restricted coverage areas

• Software Defined Radio (SDR)– Bridges the two projects horizontally

8

Wide Area Coverage for 4G

• Coordinator: Prof. Arne Svensson (Chalmers University of Technology)

• Intense research efforts are currently ongoing towards the definition of physical layers for 4G systems.

• For the downlink, there are several proposals based on– OFDM transmission techniques, and– the combination of OFDM and CDMA

9

Wide Area Coverage for 4G

• The typical parameters for the downlink include – Available downlink bandwidth is 100 MHz– Carrier frequency around 5 GHz– Maximum speed is 250 km/h

• The downlink design is simpler than the uplink design, since it is all about multiplexing within each cell.

10

Wide Area Coverage for 4G

• In the uplink, the situation is more complicated: – A combination of multiplexing and multiple access takes

place in each terminal when more than one service is transmitted at the same time.

• The uplink is normally asynchronous and oscillators in different terminals are not synchronized– It may be more difficult to use OFDM in the uplink due to

its sensitivity to frequency synchronization errors.

11

Wide Area Coverage for 4G

• Typical uplink parameters – Wide area coverage (cell of similar size as 3G)– High mobility < 250 km/h– Carrier frequency around 5 GHz– Available uplink bandwidth 40 MHz– ITU requires 100 Mbps – Multiple cell system– UMTS channel models

12

Pervasive Wireless Access for 4G

• Coordinator: Prof. Armin Wittneben, ETH Zurich• Pervasive wireless access networks imply next

generation WLANs that will provide ubiquitous connectivity – for a variety of heterogeneous nodes, e.g., RFID

tags for object identification, sensors and computers • Data rate requirements :1 Mbps - 1 Gbps• High node density and low node mobility is

foreseen

14

Pervasive Wireless Access for 4G

• Pervasive wireless access networks will exploit – Cooperative signalling– adaptive modulation and spatial multiplexing (MIMO)

for scalability and spectral efficiency– adaptive scheduling to meet heterogeneous QoS

requirements

– cooperative multiple access

– Multihop / multinode forwarding

15

Software Defined Radio

• Coordinator: Prof. Sandor Imre, Budapest University of Technology and Economics

• Inter-system roaming and handover (e.g. due to traveling or multiple coverage) would require implementation of many different standards in a single radio terminal/base station.

• Reconfigurable equipment with universal hardware and downloaded software can solve the problem efficiently.

• Easier and cost-efficient system upgrades. • Efficient design of reconfigurable radios.

16

Software Defined Radio

• The efforts are focused in– the physical layer organization (DSP-type or INTEL-

type philosophies) – downloading and reconfiguration algorithms and

protocols– Specific hardware architectures that allows, e.g.,

• reconfiguration with a minimum power consumption penalty

• dynamic adaptation to the variations in user traffic
