MBMS
- Introduced for WCDMA (UMTS) in Release 6
- Supports multicast/broadcast services in a cellular system
- Same content is transmitted to multiple users located in a specific area (MBMS service area) in a unidirectional fashion
- The Broadcast Multicast Service Center (BM-SC) node is responsible for authorization and authentication of content provider, charging, and overall data flow through Core Network (CN)
- In case of multicast, a request to join the session has to be sent to become member of the corresponding MBMS service group
- In contrast to previous releases of Universal Terrestrial Radio Access Network (UTRAN), in MBMS a data stream intended for multiple users is not split until necessary (in UTRAN, one stream per user existed both within CN and RAN)
- MBMS services are power limited and maximize the diversity without relying on feedback from users
- Two techniques are used to provide diversity:
- Macro-diversity: combining transmission from multiple cells
- Soft combining: combines the soft bits received from the different radio links prior to (Turbo) coding
- Selection combining: decoding the signal received from each cell individually, and for each TTI selects one (if any) of the correctly decoded data blocks for further processing by higher layers
- Time-diversity: against fast fading through a long Transmission Time Interval (TTI) and application-level coding
- because broadcast cannot rely on feedback, MBMS uses application-level forward error-correcting coding, namely Systematic Raptor codes
- Macro-diversity: combining transmission from multiple cells
