1. A system, comprising:
a transceiver configured to perform superposition encoding for a Multicast Broadcast Service (MBS) in wireless networks, wherein said superposition encoding is provided by transmitting high priority bits with a power level to form a high priority stream, and low priority bits with a lower power level than the high priority bits to form a low priority stream that provides different levels of protection for data streams, wherein said low priority stream is not decoded when a signal to interference noise ratio (SINR) is less than a selected level and the low priority stream is configured to be used with the high priority stream when the SINR is greater than the selected level. |
