“…The Thomson cluster process-based model is used in [18], to study the DL performance of FD networks, but uplink power control is not considered. In [19], the FD cellular network with uplink power control is analyzed using the Matèrn cluster process (MCP) and demonstrated severe reductions in mean and cell edge rate of uplink users due to high DL interference. The results also indicate that slight improvements in mean rate can be achieved by network densification with low-power BSs, nevertheless, cell edge rates are severely degraded.…”

<div><div>Full duplex (FD) communication uses the same time-frequency resource elements for uplink and downlink transmissions. Compared to half-duplex (HD) systems, this improves the effective spectrum usage, but at the cost of additional self-interference and increased co-channel interference (CCI). Promising improvements in full duplex downlink performance are well established in the literature, but the improvement in uplink is marginal or even severely degraded due to strong down-link signals. This paper focuses on managing CCI in an FD network by spatially controlling downlink and uplink transmit powers. We show that uplink performance can be improved through the introduction of downlink power control, but this slightly reduces downlink performance. We introduce a distance-based user scheduling to address this reduction. Furthermore, we have also shown that optimal overall performance can be achieved by designing appropriate uplink and downlink power control factors. We used the Matern Cluster process to model the network. The analytical results we formulated is verified by extensive Monte Carlo simulations. This work is submitted to IEEE transaction on Wireless Communications. Currently it is under review.</div></div>

“…These models are developed for different scenarios, but have in common the consideration that the coverage probability is dependent on 𝜆. Examples of such models for DL are [2], [4], [6], [8], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23].

Cellular coverage probability is independent of base station density under stochastic geometric models

Stochastic geometry (SG) has been extensively used to model cellular communications, under the assumption that the base stations (BS) are deployed as a Poisson point process in the Euclidean plane. This has spawned a huge number of articles over the past years for different scenarios, culminating in an equally huge number of expressions for the coverage probability in both the uplink (UL) and downink (DL) directions. The trouble is that those expressions include the BS density, $\lambda$, which we prove irrelevant in this article. We start by developing a SG model for a baseline cellular scenario, then prove that the coverage probability is independent of $\lambda$, contrary to popular belief.

This paper investigates the performance of cloud radio access networks (C-RAN) in different power control scenarios in full-duplex (FD) cellular networks. Results reveal that FD C-RAN performance drastically reduces with uplink (UL) power control. We proposed a power control scheme in downlink (DL), which uplifts the UL user rate, but at the cost of DL rate. With UL and DL power control, the average rate saturates after a threshold number of base stations (BS) coordination and has little impact on coordinating additional BSs. Besides, the state-of-the-art self-interference suppression (SI) of 130 dB provides almost equal performance compared to the perfect SI cancelation. Hence co-channel interference management becomes the bottleneck for FD system design. We used the Matern cluster process (MCP) to model the network.
