What’s the potential: Application Aspects
In the latest Mobile World Congress in Barcelona in Feb. 2009, many possible applications are attracting our eye-balls:
Mobile Internet
Mobile Payment

How to realize the potential:
Increase the spectrum efficiency within a cell in LTE-A:
Carrier Aggregation
8T8R scenarios are considered in two direction:
UE is aware of 8T: spatial multiplexing gain can be achieved but with higher reference signal overhead
UE is only aware of 4T: The mapping from 8T(or even more transmit antennas) to 4T can be implemented via beamforming/precoding.
In both scenarios, channel reciprocity is possibly applied
SU MIMO supported in UL
Relay: to increase the coverage in cell-edge and/or improve throughput in hot spot.
CoMP

How to realize the potential:
Increase the spectrum efficiency among cells:
Interference among neighboring cells become a serious issue to limit the performance upgrade.
So-called CoMP(Co-Ordinate Multi-Point) transmission:

How to realize the potential:
CoMP categories:
Joint Processing (JP): data is available at each point in CoMP cooperating set
Joint Transmission: PDSCH transmission from multiple points (part of or entire CoMP cooperating set) at a time
Dynamic cell seletion: PDSCH transmission from one point at a time (within CoMP cooperating set)
Coordinated Scheduling/Beamforming (CS/CB): data is only available at serving cell (data transmission from that point) but user scheduling/beamforming decisions are made with coordination among cells corresponding to the CoMP cooperating set.
