TLDR
FD communication is studied within the framework of 5th generation (5G) small cell systems in order to address its effective gain in such specific scenarios, and its performance is evaluated against a traditional HD communication.Abstract:
Full duplex (FD) communication promise of doubling the throughput of half duplex (HD) communication makes such type of system an attractive solution to cope with the expected mobile data traffic increase. Nevertheless, simultaneous transmission and reception in dense deployment scenarios increases the inter- cell interference compared to a traditional HD communication, due to a larger number of nodes simultaneously transmitting. Moreover, FD communication can only be exploited when there is traffic in both uplink and downlink directions simultaneously. In this paper, FD communication is studied within the framework of 5th generation (5G) small cell systems in order to address its effective gain in such specific scenarios. The factors that affect FD performance are analysed, and its performance is evaluated against a traditional HD communication. System level simulations show that the gain of FD over HD in the considered scenarios is lower than the expected 100% gain, with a strong dependency on the traffic and the interference conditions.read more

Can Full Duplex Boost Throughput and Delay of 5G Ultra-Dense Small Cell Networks?
TL;DR: System level results indicate that there is a trade- off between multiple-input multiple-output (MIMO) spatial multiplexing and FD in achieving the optimal system performance, and results show that FD may be useful for asymmetric traffic applications where the lightly loaded link requires high level performance.

Impact of Transport Control Protocol on Full Duplex Performance in 5G Networks
TL;DR: System level results show that FD can outperform HD and alleviate the TCP drawbacks when the inter- cell interference is not the main limiting factor, and under strong inter-cell interference, results shows that the capabilities of the system to cope with such interference dictates the gain that FD may provide over HD.

TL;DR: Cell throughput results show that the promised 100% performance gain of full duplex over traditional half duplex transmission is significantly jeopardized by the increase of the intercell interference due to the simultaneous transmission and reception, and is further reduced in case of low cell activity factor.
