1. A method for wireless communication, applied to a terminal device, wherein when a network device connected with the terminal device is switched from a source network device to a target network device, a connection between the terminal device and the source network device and a connection between the terminal device and the target network device are both maintained;
the method comprises:
sending or receiving a packet data convergence protocol (PDCP) protocol data unit (PDU) by using a new secret key and/or robust header compression (RoHC) when the terminal device satisfies a second condition;
wherein the new secret key and/or RoHC is different from an old secret key and/or RoHC, and the old secret key and/or RoHC is a secret key and/or RoHC which is used before updating when the terminal device communicates with the source network device and/or the target network device.
