Activation method and apparatus of the uplink closed loop transmit diversity

摘要

Disclosed are a method and device for activating uplink closed loop transmit diversity (UL CLTD). The method comprises: a NodeB receives configuration information for the UL CLTD from a radio network controller, wherein the configuration information for the UL CLTD comprises an information element carrying the UL CLTD active status, and the information element carrying the UL CLTD active status is used for indicating an active status to be used when the NodeB activates the UL CLTD of a user equipment (UE); the NodeB activates the UL CLTD of the UE using the active status indicated by the information element carrying the UL CLTD active status. The present invention solves the problem in the prior art of the unclearness of which active status is to be used as the initialized active status, so as to ensure the implementation of the UL CLTD function.
