Patent ID: 8817647

Claim:
A method comprising: obtaining channel state information (CSI) feedback for multiple downlink component carriers (CCs) by a user equipment (UE) in a multi-carrier wireless communication network, wherein each downlink CC is associated with a feedback mode, and wherein each feedback mode comprises a set of feedback types to be reported to a base station at time slots configured by an upper layer; determining a prioritized downlink CC for CSI reporting based on feedback types and feedback modes to be transmitted for each downlink CC at a given time slot, wherein different feedback types are organized into feedback type groups based on CSI information types, wherein multiple feedback types within the same feedback type group share the same priority level, wherein different feedback modes are organized into feedback mode groups based on transmission modes, and wherein multiple feedback modes within the same feedback mode group share the same priority level; and transmitting corresponding CSI feedback for the prioritized downlink CC over a primary uplink CC.
