“…In addition to the large-scale fading and small-scale fading mentioned above, the angle fading of directional antenna is also considered in this paper [22]. According to the characteristic of directional antenna, only when users are within the range of effective radiation angle of directional antenna Ψ, Ψ ∈ ð0, 2π, they can receive the interference or desired signals; otherwise, the links are broken.…”

The traditional cellular architecture where devices connect to their service base station (BS) may cause poor performance especially for edge users. Device-to-device (D2D) communication enables nearby user as a relay to help BS forward information, thereby improving the network coverage and quality of service (QoS) of edge users. This paper proposes a distance-based D2D matching mechanism for general cellular networks, where a relay user who successfully connects to its targeted BS can transmit data to its closest user for D2D communication. A link of BS to D2D pair contains two sublinks, which occur at different time phases in each cell. Assuming a nonsynchronous system, we consider that there exists cross-layer interference for D2D links. Based on the techniques of stochastic geometry, we develop the performance of coverage probability and ergodic rate of the D2D network. A key intermediate step in this analysis is the derivation of the interference expressions for D2D links caused by BSs and cochannel D2D users. Then, we derive the meta distribution of the signal-to-interference ratio (SIR) to capture the performance changes of individual links. Simulation results demonstrate that our matching mechanism based on the appropriate time resource allocation favors the edge users with a higher probability of successful communication and transmission rate.

“…In [9][10][11], the authors proposed a three-dimensional directional network model to improve link reliability and system throughput by controlling ICI. A novel angle attenuation model was designed to simulate the angle declination of interference links in directional UDNs [12]. A virtual antenna array model and window function fltered weighting method based on directional antennas were proposed [13].…”

“…For writing convenience, the subscript 1 of R 1 is omitted. Besides, this paper also considers the angle fading model of interference signal in [12]. Te angular fading follows an exponential distribution, which only depends on the angle ofset between the user position and the beam aiming directions of its interference BSs, i.e., ξ(θ i ) � e − |θ i | , where θ i is an i.i.d random variable that represents the value of the angle ofset between the location of u o and the antenna boresight directions of its interfering BS.…”

Intercell interference coordination (ICIC) plays a significant role in strengthening ultra-dense network (UDN) downlink coverage. From a statistical average perspective, a user is primarily interfered by its adjacent base station (BS), especially the second nearest BS. By modeling BSs equipped with directional antennas as a Poisson point process (PPP), this paper proposes a dynamic spectrum resource allocation strategy mainly about users’ service BS and its nearest interference BS, where the subchannel assigned by the typical (served) user is interlaced from the channel simultaneously occupied by users within the effective radiation range of its second nearest BS. To fully explore this scheme for directional networks, we develop analytical expressions in terms of success probability and ergodic rate for the typical user based on the techniques of stochastic geometry, taking into account the fading of directional BS radiation angle. Then, we derive the meta distribution of the signal-to-interference ratio (SIR) for capturing individual link performance changes of users. Simulations verify the correctness of numerical results, and it is revealed that this strategy is in favor of users alleviating interference from their second nearest BSs and the performance advantages of the proposed ICIC strategy are better than those of the traditional directional UDNs.

In the existing literature, for the spatial‐temporal characteristic of ultra‐dense network performances, the joint coverage probability is used to measure the correlation between different links or time‐slots due to channel and topological stability. However, the time‐variation introduces randomness and decreases correlation temporally and spatially due to user mobility, path‐loss and channel fading. In this paper, the expression of the joint coverage probability is derived to simultaneously analyze the effect of correlation and fluctuation among different time‐slots in ultra‐dense mobile networks by stochastic geometry. Specifically, the typical user moves out of the transmission range of the base station with handoff skipping and traditional handoff. In addition, the distance variation caused by the user's movement is considered in the analysis of the temporal correlation and the joint coverage probability. Simulation shows that the temporal correlation coefficient under handoff skipping is gradually greater than that under traditional handoff. The analytical results highlight the differences between the proposed network performance analysis and traditional analysis, validated through simulation.
