Multimedia broadcast multicast service: new transmission schemes and related challenges

摘要: MBMS (Multimedia Broadcast Multicast Service) is a service offered by 3GPP (3rd Generation Partnership Project) cellular networks for the distribution of multimedia content and competes with technologies like DVB-H (Digital Video Broadcasting - Handhelds) DMB Multimedia Broadcasting). For in LTE (Long Term Evolution), discussed two different radio transmission schemes: one cells transmitting an uncoordinated way synchronously such that signals from several are perceived as signal at user terminal. We will discuss related challenges choice suitable scheme, coordination base stations synchronized content, mobility between areas schemes.
