Contribution Highlights
• TV spectrum Usage - NPRM Update (11-040803-00)
– NPRM proposes operation of low-power portable
transmitters, and higher-power fixed devices
– These are unlicensed devices which co-exist with
TV broadcasters on a non-interfering basis
– Vacant channels identified to unlicensed devices by
broadcast control signals, geolocation, and/or
professional installation

Contribution Highlights
• Cooperative Transmission Schemes for Capacity Increase in ‘3G
and Beyond’ Wireless Systems (11-04-0797-00)
Submission
–
Cooperation schemes are able to provide multiplexing and diversity
gains even if terminals use a single antenna, by using STBC borrowed
from MIMO systems
–
High gains may be observed for structured and unstructured relaying
–
Capacity approaching schemes may be based on A&F or D&F different
implications for the complexity of the terminals and the design of the
MAC layer
–
The A&F solution is a good compromise between performance and
complexity of the relay node
