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.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for processing downlink data. Background technique [0002] Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) is a third-generation mobile communication system that uses Wideband Code Division Multiple Access (WCDMA) air interface technology. The UMTS system is usually called a WCDMA communication system. The UMTS system adopts a structure similar to that of the second generation mobile communication system, including a radio access network (RAN, Radio Access Network) and a core network (CN, Core Network). [0003] With the evolution of each version of UMTS, in order to meet the growing needs of wireless services, the Multiple Input Multiple Output (MIMO, Multi Input Multi Out put) and high-order 64 quadrature (amplitude) modulation (QAM, Quadrature (Amplrude) Modulation), 3GPP Release 8 adopts ...
