Radio Interface for Broadcast/Multicast Services
The present document shall provide a general overview on radio interface related aspects of broadcast/multicast services. This report covers stage 2 and stage 3 aspects of the radio interface.
This report is organised as follows: clause 4 gives an overview on the broadcast/multicast services and their requirements. Clause 5 provides a common model and describes aspects common to all point-to-multipoint services. Clause 6 is devoted to the Cell Broadcast Service describing the impacts on the interface functions and the protocol aspects. The present document covers only those items, which are in the scope of 3GPP TSG RAN WG 2. Information from Technical Specifications or other documents are provided when it is necessary to understand the requirements described.
