Title: Dynamic Uplink/Downlink Resource Management in Flexible Duplex-Enabled Wireless Networks,
Abstract: Flexible duplex is proposed to adapt to the channel and traffic asymmetry for
future wireless networks. In this paper, we propose two novel algorithms within
the flexible duplex framework for joint uplink and downlink resource allocation
in multi-cell scenario, named SAFP and RMDI, based on the awareness of
interference coupling among wireless links. Numerical results show significant
performance gain over the baseline system with fixed uplink/downlink resource
configuration, and over the dynamic TDD scheme that independently adapts the
configuration to time-varying traffic volume in each cell. The proposed
algorithms achieve two-fold increase when compared with the baseline scheme,
measured by the worst-case quality of service satisfaction level, under a low
level of traffic asymmetry. The gain is more significant when the traffic is
highly asymmetric, as it achieves three-fold increase.
