A method and apparatus for identifying joint transmissions in unlicensed spectrum are described, including receiving, at a user equipment (UE), a frame from one or more network entities over a contention-based medium, wherein the frame includes a preamble. The method and apparatus further include determining whether the frame corresponds to a unicast transmission or a joint transmission based on the preamble. In another aspect, a method and apparatus include determining, at a network entity, whether a frame corresponds to a unicast transmission or a joint transmission. The method and apparatus include transmitting the frame with a preamble to a UE over a contention-based medium, the preamble being based on determining whether the frame corresponds to the unicast transmission or the joint transmission. For example, the type of scrambling applied to the preamble may be based on whether the frame corresponds to unicast transmission or joint transmission. |
