Abstract
A data transmission method and an apparatus in a network supporting coordinated multipoint transmission are provided. The method includes transmitting candidate sets of initial state information used to generate Demodulation Reference Signal (DMRS) scrambling sequences for the transmission points to the UE, and transmitting an indication corresponding to at least one candidate set of initial state information respectively associated with at least one transmission point to the UE, wherein the initial state information is used by the UE to generate DMRS scrambling sequences.
