Abstract: Driven by new services and terminal capabilities, mobile
data traffic has grown dramatically over the past several years
and is continuing to grow rapidly. According to a forecast by
Cisco, the global mobile data traffic grew 70 percent in 2012,
and will increase 13-fold between 2012 and 2017. As a result,
there is an explosive demand for wireless data capacity. This demand
for data may be met by (i) new spectrum,(ii) more efficient use of
spectrum: shared UL/DL spectrum (dynamic TDD) has been proposed with
this goal in mind, and (iii) increasing cell density, allowing spatial
reuse of resources to increase system capacity. In this presentation,
we propose and evaluate two techniques for spectrum efficiency
improvement, namely, the dynamic TDD and full-duplex relaying. For
dynamic TDD, we apply results from stochastic geometry to derive
expressions for the distribution of DL signal to interference plus
noise ratio (SINR) at an arbitrary UE and the distribution of UL SINR
at its serving base station (BS). System level simulations are also
conducted to evaluate the performance of dynamic TDD and the related
interference issues under more general and realistic system
assumptions. Then a frequency domain interference coordination
technique is provided, and the superior performance of the proposed
scheme over conventional frequency reuse technique and no interference
coordination scenario is verified by system level simulations. For
full-duplex relaying, we investigate the optimal resource allocation
(both power and relay location) for full-duplex decode-and-forward (DF)
relaying systems. Analytic and numerical results are provided
to demonstrate advantages of the resource optimization.
