Analytic Evaluation of a Hybrid Broadcast-Unicast TV Offering
2008
VTC Spring 2008 - IEEE Vehicular Technology Conference
A not so well known feature of MBMS is its support for hybrid broadcast-unicast transmission. ...
Since unicast transmission does not scale very well if mobile TV becomes a true mass service, 3GPP has defined a broadcast extension for UMTS, called Multimedia Broadcast Multicast Service (MBMS). ...
This situation is depicted in Figure 1 . Hybrid broadcast-unicast transmission was already addressed in [3] using simulations. ...

Using Layered Division Multiplexing for Mixed Unicast-Broadcast Service Delivery in 5G
2019
2019 IEEE International Symposium on Broadband Multimedia Systems and Broadcasting (BMSB)
This thesis shows in many cases, capacity of the current multi-cell unicast service is limited by co-channel interference. Using a reduced transmission power will not impact the system performance. ...
This provides a good opportunity to apply layered division multiplexing (LDM) to combine broadcast and unicast services in one RF channel by power sharing. ...
