This paper analyzes a spectrum reuse scheme based on region division for secondary users in cognitive radio networks with outage constraint of the primary user. The secondary users can reuse the spectrum by sharing the primary user's uplink (UL) frequency resources in the system. With the help of the stochastic geometry, the secondary user reusing the frequency spectrum can be modeled as the probability...
In frequency reuse one networks, the inter-cell interference (ICI) is severe especially for cell edge user equipments (UEs). Statistical information of ICI is helpful to design interference mitigation schemes. This paper proposes a statistical model for the uplink ICI in orthogonal frequency division multiple access (OFDMA) networks with power control. The distance-dependent attenuation and correlated...
This paper analyzes a spectrum access scheme based on region division for Device-to-Device (D2D) communication underlaying cellular networks with outage constraint for cellular communication. The D2D pairs will access the spectrum by sharing the cellular uplink (UL) frequency resources in the networks. By utilizing stochastic geometry, D2D accessing the frequency spectrum can be modeled as the probability...
