Description
Summary:3GPP Release 14 has further improved eMBMS to enable the provision of television services according to requirements commonly found in the broadcasting industry. The improvements include several radio interface enhancements such as the support for larger inter-site distances in SFN deployments, the introduction of a dedicated eMBMS carrier with 100% broadcast resource allocation complete with a new, lower overhead subfrarne, stripping out the unicast control region. Studied in this paper are the main innovations introduced in Release 14 with respect to SFN coverage performance. Analysis has been carried out for low power low tower (LPLT) i.e. cellular networks and high power high tower (HPHT) networks typical in broadcasting today. Special focus is given to providing reception to fixed roof-top antennas, broadcasters' main coverage mode.
