4G Long-Term Evolution (LTE) has been selected by the U.S. federal and EU authorities to be the access technology for public safety broadband networks (PSBNs) that would allow first responders to seamlessly communicate between agencies nationwide. From Release 11 on, 3rd Generation Partnership Project (3GPP) has been outlining the standards for the features that will enable LTE to be used as part of a PSBN. The requirements for scheduling user equipments (UEs) with appropriate quality of service (QoS) and priority has not been addressed yet. In this paper, we highlight the scheduling challenges in PSBNs and propose a solution which considers all the QoS parameters. Proposed algorithm minimizes packet losses while scheduling packets in a priority and QoS aware fashion. Simulations results illustrate superiority of the proposed scheduler.
