Abstract
The embodiment of the invention discloses a method and a device for processing downlink data. The method comprises the following steps that: a radio network controller (RNC) distributes joint scramblers for user equipment (UE); the RNC transmits a second radio resource control (RRC) message to all the cells of a cooperation cell set, wherein the second RRC message carries the joint scramblers distributed for the UE, so that all the cells of the cooperation cell set use the joint scramblers to scramble the downlink data; and the RNC transmits a first RRC message to the UE, wherein the first RRC message carries the joint scramblers distributed for the UE, so that the UE descrambles the joint scramblers according to the joint scramblers after receiving the scrambled downlink data. Due to different quality of channels between a plurality of cells and the UE, the UE can perform diversity reception by completely utilizing different channel quality to acquire lower frame error rate and higher throughput and improve the properties of the UE.
