Wireless communication method, first terminal, and communication device

1 . A method for wireless communication, comprising:

receiving, by a first terminal, a first message from a second terminal, the first message being configured for instructing the first terminal to perform data transmission using at least one path in a plurality of paths and instructing the first terminal to activate or deactivate a Packet Data Convergence Protocol (PDCP) duplication function; and

performing the data transmission based on the at least one path.

2 . The method of claim 1 , wherein each of the at least one path is a connection path from the first terminal to a network device.

3 . The method of claim 2 , wherein the plurality of paths comprises a relay path and a direct connection path, the relay path is a path in which the first terminal is connected to the network device through the second terminal, and the direct connection path is a path in which the first terminal is directly connected to the network device; or, the plurality of paths only comprises relay paths.

4 . The method of claim 1 , wherein the first message comprises any one of:

Radio Resource Control (RRC) signaling, a Media Access Control (MAC) Control Element (CE), or Downlink Control Information (DCI).

5 . The method of claim 1 , wherein the first message is configured for instructing the first terminal to perform the data transmission using at least two paths in the plurality of paths and for instructing the first terminal to activate the PDCP duplication function, and same data is transmitted on different paths of the at least two paths.

6 . The method of claim 1 , wherein the first message is configured for instructing the first terminal to perform the data transmission using one path or at least two path paths in the plurality of paths and for instructing the first terminal to deactivate the PDCP duplication function, different data is transmitted on different paths of the at least two paths.

7 . The method of claim 1 , wherein the first terminal is a remote terminal.

8 . A first terminal, comprising: a processor and a memory for storing a computer program,

wherein the processor is configured to call and run the computer program stored in the memory to cause the first terminal to:

receive a first message from a second terminal, the first message being configured for instructing the first terminal to perform data transmission using at least one path in a plurality of paths and instructing the first terminal to activate or deactivate a Packet Data Convergence Protocol (PDCP) duplication function; and

perform the data transmission based on the at least one path.

9 . The first terminal of claim 8 , wherein each of the at least one path is a connection path from the first terminal to a network device; and

the plurality of paths comprises a relay path and a direct connection path, the relay path is a path in which the first terminal is connected to the network device through the second terminal, and the direct connection path is a path in which the first terminal is directly connected to the network device.

10 . The first terminal of claim 8 , wherein the first message is configured for instructing the first terminal to perform the data transmission using at least two paths in the plurality of paths and for instructing the first terminal to activate the PDCP duplication function, and same data is transmitted on different paths of the at least two paths.

11 . The first terminal of claim 8 , wherein the first message is configured for instructing the first terminal to perform the data transmission using one path or at least two paths in the plurality of paths and for instructing the first terminal to deactivate the PDCP duplication function, different data is transmitted on different paths of the at least two paths.

12 . A communication device, comprising: a processor and a memory for storing a computer program,

wherein the processor is configured to call and run the computer program stored in the memory to cause the communication device to:

transmit a first message to a first terminal, the first message being configured for instructing the first terminal to perform data transmission using at least one path in a plurality of paths and instructing the first terminal to activate or deactivate a Packet Data Convergence Protocol (PDCP) duplication function.

13 . The communication device of claim 12 , wherein each of the at least one path is a connection path from the first terminal to a network device; and

wherein the plurality of paths comprises a relay path and a direct connection path, the relay path is a path in which the first terminal is connected to the network device through the communication device, and the direct connection path is a path in which the first terminal is directly connected to the network device; or, the plurality of paths only comprises relay paths.

14 . The communication device of claim 12 , wherein the first message is configured for instructing the first terminal to perform the data transmission using at least two paths in the plurality of paths and for instructing the first terminal to activate the PDCP duplication function, and same data is transmitted on different paths of the at least two paths; or,

the first message is configured for instructing the first terminal to perform the data transmission using one path or at least two paths in the plurality of paths and for instructing the first terminal to deactivate the PDCP duplication function, different data is transmitted on different paths of the at least two paths.
