Abstract
In this paper, we analyse the outage probability of Device-to-Device (D2D) communications in a multi-cell frequency reuse-1 (FRF-1) system. We derive a formula for outage probability of a D2D link in the FRF-1 system when uplink resource sharing between cellular users and D2D users is enabled in the network. Based on this analysis, we propose a location-based power control mechanism for D2D which can enhance the outage performance of the D2D link, and at the same time, reduce the transmit power required for communication.
Highlights
In recent years Device-to-Device (D2D) underlay in cellular networks has attracted a lot of attention
The results show that distance-constrained resource-sharing criterion (DRC) brings significant reduction of outage probability of the D2D link
To analyse the performance of the D2D link in an frequency reuse-1 (FRF-1) network, we derive an expression for outage probability of the D2D receiver, which is defined as the probability that instantaneous signal-to-noise and interference ratio (SINR) γDR falls below a predetermined SINR threshold γ0
Summary
In recent years Device-to-Device (D2D) underlay in cellular networks has attracted a lot of attention. Considering the D2D underlay, it is often assumed that D2D communications may use radio resources simultaneously with cellular users. In this paper we analyse a D2D underlay reusing cellular uplink (UL) resources in frequency reuse-1 (FRF-1) network which aims at maximizing effectiveness of bandwidth use. We derive a formula for outage probability of a D2D link in a multi-cell FRF-1 system and propose a location-based power control mechanism for D2D communication.
