Abstract:
Beyond Fifth Generation (B5G) network aims to provide a very high data rate with minimum latency to an ultra-dense
user environment. To achieve this demand, the possible approaches are network-centric and device-centric approach. In
a network-centric approach, a new frequency band is introduced, and the existing network infrastructure is modified. The
device-centric approach does not require any modification in the existing network infrastructure, and the demand of B5G
network is achieved through optimum resource allocation methodology. Device-to-Device (D2D) is an effective devicecentric approach that supports the B5G network. In this paper, we propose a dynamic sectorization technique in which
eNodeB (eNB) varies the number of sectors dynamically in the network and allocates the Resource Block (RB) to D2D
users. Sectoring improves Signal-to-Interference-Noise-Ratio (SINR) and network performance. We derive an expression for the probability of successful transmission and threshold to make a decision on the number of sectors based on
available RBs and D2D users in the network. Further, dynamic sectoring helps eNB to perform parallel processing for
reducing the denial of the request. Simulation results validate the probability of successful transmission of D2D pairs
with available RBs and the effectiveness of parallel processing to reduce the denial of request with improved SINR.
