Abstract
The invention provides a method and device for sending MBMS traffic data based on MBMS Cell Group, the method comprises the following steps: channel coding and modulating said MBMS traffic data; determining said MBMS cell group-specific scrambling code; determining said MBMS cell-specific scrambling code; scrambling said MBMS traffic data with said MBMS cell group-specific scrambling code, and adding reference signal scrambled with said MBMS cell group-specific scrambling code and reference signal scrambled with said MBMS cell-specific scrambling code; and sending scrambled MBMS reference signal and data. With the method and the corresponding device provided by the invention, it is easy to realize RF combining or RF combining and soft combining simultaneously at UE to obtain diversity gain.
