Abstract: Methods and apparatuses in a wireless communication system is provided. Configuration information for defining a downlink assignment for a bandwidth part (BWP) is transmitted to a user equipment (UE) by higher layer signaling. At least one BWP is configured in a cell of the base station and the higher layer signaling is UE specific. An activated BWP is identified. Downlink control information (DCI) is transmitted on the activated BWP. Data is transmitted to the UE on the activated BWP according to the downlink assignment for the activated BWP. The downlink assignment is defined on the activated BWP, based on both the configuration information by the higher layer signaling and remaining information by the DCI.
