Abstract
A method and apparatus can be configured to determine uplink-downlink configuration for a primary cell and at least one secondary cell. The method can also include broadcasting the uplink-downlink configuration to user equipment. The user equipment is configured for carrier aggregation. The method can also include enabling dynamic time-division-duplex configuration for the primary cell and/or the at least one secondary cell for the user equipment. The method can also include configuring the user equipment with downlink hybrid-automatic-repeat-request reference uplink-downlink configuration for each cell for which dynamic time-division-duplex configuration is enabled. The method can also include deriving uplink and/or downlink hybrid-automatic-repeat-request-acknowledgement timing for the at least one secondary cell based on at least one configured uplink-downlink configuration and at least one downlink hybrid-automatic-repeat-request reference uplink-downlink configuration.
