Method and device for wireless communication

A second node for wireless communications, comprising:

• a second transmitter, transmitting a first signaling and a second signaling;
• the first signaling configuring at least one Radio Link Control (RLC) entity of a first cell group, while the second signaling configuring at least one RLC entity of a second cell group;
• and
• a second receiver, receiving a first message, the first message requesting a stop of transmission for a target cell group within a first time window set;
• the first time window set at least comprising one time window;
• wherein the target cell group is one of the first cell group or the second cell group, where each of the first cell group and the second cell group respectively comprises at least one cell;
• at least one of the at least one RLC entity of the first cell group or the at least one RLC entity of the second cell group is maintained in the first time window set.
