Data transmission method and apparatus in network supporting coordinated transmission

摘要

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.

1. A data transmission method for a Base Station (BS), the method comprising:
transmitting a plurality of cell identifiers to generate Demodulation Reference Signal (DMRS) scrambling sequences to a user equipment (UE); and transmitting an indication, indicating a scrambling index to the UE; and transmitting the generated DMRS scrambling sequences based on the scrambling index and one of the plurality of cell identifiers to the UE, wherein the one of the plurality of cell identifiers is determined using the scrambling index.
