Abstract EN
In a full duplexing (FD) wireless cellular network, a base station operates in FD mode, while the downlink (DL) and uplink (UL) users operate in half duplexing (HD) mode.
Thus, the downlink and uplink transmissions occur simultaneously so that interuser interference from a UL to a DL user occurs.
In an FD network, the main challenge to minimize the interuser interference is user pairing, which determines a pair of DL and UL users who use the same radio resource simultaneously.
We formulate a nonconvex optimization problem for user pairing to maximize the cell throughput.
Then, we propose a heuristic user pairing algorithm with low complexity.
This algorithm is designed such that the DL user having a better signal quality has higher priority to choose its paired UL user for throughput maximization.
Thereafter, we conduct theoretical performance analysis of the FD cellular system based on stochastic geometry and analyze the impact of the user paring algorithm on the performance of the FD cellular system.
Results show that the FD system that uses the proposed user pairing algorithm effectively reduces the interuser interference and approaches optimal performance.
It also considerably outperforms the FD system using a random user pairing and almost doubles the conventional HD system in terms of cell throughput.
