OVERLAY UNICAST OR MBSFN DATA TRANSMISSION ON TOP OF MBSFN TRANSMISSION |
| 摘要 |
Methods, systems, and devices are described for increased wireless communications system capacity through hierarchical modulation of multiple transmission layers during certain transmission subframes in a wireless communications system. Various deployment scenarios may be supported that may provide communications modulated on both a base modulation layer as well as on an enhancement modulation layer that is superpositioned on the base modulation layer. Reference signals may be provided for channel estimation for both the base modulation layer and enhancement modulation layer. |

1. A method for wireless communications, comprising:
transmitting a multicast broadcast single frequency network (MBSFN) transmission during a first transmission period on a base modulation layer; and transmitting a unicast transmission during the first transmission period on an enhancement modulation layer that is superpositioned on the base modulation layer. |
