Abstract:
1. A method for communication in a wireless telecommunication system, the method comprising: determining, by a network element, that a physical uplink shared channel (PUSCH) transmission scheduled on a subframe of a secondary cell (SCell) requires an acknowledgement/negative acknowledgement (ACK/NACK) on a downlink subframe of a primary cell (PCell) associated with the Network element; and provisioning, by the network element, for a carrier aggregation-capable user equipment (UE), in a control region of the downlink subframe, at least one resource for a physical HARQ (hybrid automatic repeat request) indicator channel (PHICH), wherein the downlink subframe is not configured for a PHICH resource in an uplink/downlink configuration for operations using only the primary cell (PCell) associated with the network element.
