Abstract

In many public safety scenarios, Device-to-Device (D2D) communication should be capable of handling out-of-coverage situations, ensuring that D2D devices can communicate directly without the aid of network infrastructure. While a number of resource allocation schemes for D2D communication in Long-Term Evolution (LTE) have been proposed, the majority consider only in- coverage scenarios that rely on a centralized controller to coordinate among D2D devices, and are unable to handle out-of-coverage communication. To address this issue, in this paper we investigate a set of distributed resource allocation schemes for out-of-coverage D2D group communication. To be specific, we first provide guidelines concerning how to allocate D2D resources based on Modulation and Coding Scheme (MCS), Physical Resource Block (PRB) size, and Time Resource Pattern (TRP) to meet the QoS requirements of applications. We then design three distributed resource allocation schemes that select PRBs in the resource pool and/or adjust the transmitting power based on the level of available information about the network environment. To evaluate the designed distributed resource allocation schemes, we conduct extensive performance evaluation, validating their effectiveness in a variety of deployment scenarios.
