Abstract:
Methods, systems, and devices are described for dynamic cell mode indication and reporting channel and interference feedback for dormant cells in a carrier aggregation environment. Indicators of cell mode for one or more secondary cells are sent using a transmission mechanism and may configure active or dormant sub-periods within the indicated periods. Indicators of cell mode for a secondary cell may be transmitted on a carrier of the primary cell, or the indicators may be transmitted on carriers of the secondary cell. Dormancy may also be indicated by the presence or absence of a cell mode indicator for predetermined time periods. When CSI measurements occur for a carrier of a dormant cell, the UE may report CSI for the dormant periods, suppress CSI reporting for the dormant periods, adjust a reporting frequency for the dormant periods, or report some types of CSI and not others for the dormant periods.
