Mobile Video Transmission Using Scalable Video Coding


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
