Message(s) are received that comprise configuration parameters of a cell. The cell comprises a first downlink BWP, a second downlink BWP and uplink BWP(s). The configuration parameters comprise: first parameters of first uplink control channel resource on the at least one uplink BWP for first CSI reports of the first downlink BWP; and second parameters of second uplink control channel resource on the uplink BWP(s) for second CSI reports of the second downlink BWP. The first CSI reports of the first downlink BWP are transmitted via the first uplink control channel resource on an uplink BWP of the uplink BWP(s). An active BWP is switched from the first downlink BWP to the second downlink BWP. The second CSI reports of the second downlink BWP are transmitted, after the switching, via the second uplink control channel resource on the uplink BWP of the uplink BWP(s).
