BWP handling in idle mode and inactive mode
Described are methods, apparatuses, and computer program products for bandwidth part (BWP) handling. Apparatus can receive information on limitation(s) of BWP(s) supported in a cell of the base station and inhibit a terminal from accessing the cell based on limitation(s) of the BWP(s) supported in the cell and limitation(s) of BWP(s) supported by the terminal. Apparatus can select access parameter(s) based on limitation(s) of the BWP(s) supported in the cell and limitation(s) of the BWP(s) supported by the terminal, and instruct the terminal to reselect/camp on the cell using the access parameter(s). BWP(s) supported by the terminal can include a network BWP usable for early data transmission. Apparatus can allow/inhibit cell access by terminal based on, e.g., type of access or terminal type. Apparatus can instruct base station to provide information on limitation(s) of BWP(s) provided by the base station. Each BWP can be subcarrier spacing specific.
