Patent ID: 8885747

Claim:
An information processing method, comprising: receiving, by a user equipment (UE), a Precoding Control Indication (PCI); determining, by the UE, a target PCI according to the received PCI; determining, by the UE, a weighting factor corresponding to the target PCI; and applying, by the UE, the weighting factor to send data in an uplink closed-loop transmit diversity manner; wherein the determining, by the UE, the target PCI according to the received PCI comprises: if the received PCI comprises multiple PCIs sent by all or part of cells from a serving Enhanced Dedicated Channel (E-DCH) radio link set of the UE, determining, by the UE, a PCI combined from the multiple PCIs sent by all or part of the cells from the serving E-DCH radio link set of the UE as the target PCI, wherein the multiple PCIs are generated by a NodeB controlling the cells from the serving E-DCH radio link set of the UE with a same PCI value.
