US Patent 9198050 Device and method for improved closed loop diversity

A NodeB for an HSPA enabled WCDMA network, arranged to transmit beam forming instructions to a User Equipment, a UE, which is arranged for beam forming. The beam forming instructions comprise information identifying a code book with one or more code words, and the NodeB is also arranged to transmit code words from said code book to the UE at a certain rate. The NodeB is further arranged to determine said rate based on dynamically varying information available in the WCDMA network, and to receive said information on the code book from an RNC upon configuration of the UE or to choose code book based on said dynamically varying information available in the WCDMA network.
