Periodic channel state information reporting for time division duplex (TDD) carrier aggregation systems

Abstract:

Technology for a user equipment (UE) operable to report periodic channel state information (CSI) to an eNodeB is disclosed. The UE can determine a reporting period (N.sub.pd) of a serving cell of the UE. The UE can determine a Time-Division Duplex (TDD) uplink-downlink (UL-DL) configuration of a primary cell of the UE. The UE can encode multiple periodic CSI reports for transmission to the eNodeB using a physical uplink control channel (PUCCH) on the primary cell according to the reporting period N.sub.pd.
