| Popis: | Dedicated public safety systems have been originally used to deliver the communications for public services such as police and fire departments. These systems are based on standards such as Terrestrial Trunked Radio (TETRA) which have been designed to meet specifically the requirements of public safety communications. However, with the emergence of new applications requiring mobile broadband capabilities, Long Term Evolution (LTE) networks have been selected by many agencies to be the baseline technology for future public safety networks. In Release 13, 3rd Generation Partnership Project (3GPP) has investigated Single-Cell Point-to-Multipoint (SC-PtM) transmission as an enabler for group communication required by public services, utilizing enhanced Multimedia Broadcast Multicast Service (eMBMS) of LTE. In order to reduce the uplink signaling overhead and to ease the implementation, a new transmission scheme for SC-PtM relying only on Channel Quality Indicator (CQI) feedback is proposed in this paper. The new transmission scheme has been compared with other existing SC-PtM transmission schemes, Unicast and Multimedia Broadcast Single Frequency Network (MBSFN). Simulation results have shown that the proposed scheme has a similar performance as SC-PtM transmission scheme requiring both CQI and Hybrid Automatic Repeat Request (HARQ) indication feedback, yet with lower uplink overhead and implementation complexity. |
