Abstract
The present document gives guidelines for the implementation of Digital Video Broadcasting (DVB) interaction channel for Satellite Distribution System (also known as DVB RCS: DVB Return Channel via Satellite) in mobile scenarios.
DVB RCS specification [i.1] describes several mandatory and optional features for geostationary satellite interactive system in mobile scenarios. Annex L of TR 101 790 [i.3] already defines guidelines for some mobility scenarios characterized by Line-Of-Sight conditions with a channel that can be characterized as AWGN. This present document draws attention to the technical questions that need to be answered in setting up a DVB RCS network that supports mobility in Line of Sight and Non Line of Sight scenarios in different channel conditions and offers some guidance in finding answers to them. The present document considers the DVB-S2 standard [i.2] for the forward link transmission with the features to support mobility described in the DVB-RCS specification.
