Also, when the data difference that data and the 4th data packet that first data packet carries carry, second number It is different according to the HARQ process ID of packet and the HARQ process ID of third data packet.

Specifically, destination network device #A can send data #E (that is, the second data packet is another to terminal device Example), source network device #B can send data #F to terminal device, wherein data #E is different with data #F.

In this case, there may be destination network device #A and source network device #B to use identical HARQ process, In other words, the case where identical HARQ process ID is carried in the data for being transferred to terminal device, thus, terminal is set The standby retransmission process carried out using identical HARQ process for data #E and data #F, thus, for example, it may be possible to need It is transmitted to data caused by the retransmission process for data #E of destination network device #A or signaling is accidentally sent to source The case where network equipment #B, or, in fact it could happen that need to be transmitted to the retransmission process for data #F of source network device #B The case where generated data or signaling are accidentally sent to destination network device #A, leads to error of transmission.

In contrast, in embodiments of the present invention, when data #E is different with data #F, destination network device #A and source net Network equipment #B can negotiate used HARQ process ID by first parameter sets, it can be ensured that terminal device makes It is carried out respectively with different (that is, corresponding different HARQ process ID) HARQ process for data #E and data #F Retransmission process, and then can ensure that data caused by the retransmission process for data #E or signaling can be transmitted accurately To destination network device #A, data caused by the retransmission process for data #F or signaling can accurately be transmitted to source net Network equipment #B.
