| الوصف: | Device-to-Device (D2D) communication is a key technology for future wireless networks, allowingdevices to communicate directly without relying on a cellular infrastructure. Millimeter wave (mm-Wave) communication utilizes high-frequency radio, providing very large bandwidths for fast and reliable D2D transmissions. However, mmWave frequencies have high attenuation, requiring devices to have multiple antennas and perform beamforming. The success of beamforming requires beam training. The beam misalignment can impact the performance of the network. To address these challenges, our study focuses on the theoretical analysis of the performance of mmWave D2D communications within the context of Ultra-Reliable Low Latency Communications(URLLC). We use stochastic geometry and queuing theory to evaluate both spatial and temporalvariations in performance from two different perspectives: the instantaneous average properties of the random network and the global stability properties of a dynamic network with random service requests. For the dynamic properties, we focus on the stability condition of D2D network by introducing directional antennas arrays for the D2D users. The network is modeled based on a spatial birth-death process. For the instantaneous properties, we mainly care about the meta-distribution of the network, which is a metric that accounts for the spatial distribution of coverageprobability. We derive the meta-distribution of the effective rate as a statistical latency guarantee for URLLC communications, by considering both the training overhead and misalignment for a D2D network with beamforming. At last, we propose methods to choose the optimal number of antennas and to allocate resource for beam training. ; La communication de terminal à terminal (D2D) est une technologie clé pour les futursréseaux sans fil. Elle permet aux appareils de communiquer directement, sans avoir besoin d’une infrastructure cellulaire. La communication en ondes millimétriques (mmWave) utilise des fréquences radio de haute ... |
