In one example, if the RLC SDU segment that the multiple needs determined in step 201 retransmit includes: RLC SDU
Segment 1, RLC SDU segment 2 and RLC SDU segment 3, then RLC SDU segment 1 is right when retransmitting RLC SDU segment 1 again
The re-transmission recording parameters RETX_COUNT1 answered adds 1；When retransmitting RLC SDU segment 2 again, RLC SDU segment 2 is corresponding heavy
It passes recording parameters RETX_COUNT2 and adds 1；When retransmitting RLC SDU segment 3 again, the corresponding re-transmission of RLC SDU segment 3 record
Parameter RETX_COUNT3 adds 1.
In step 204, for each re-transmission recording parameters, when the re-transmission recording parameters reach default maximum retransmission
When, instruction rrc layer has reached default maximum retransmission.
An example is connected, if the corresponding re-transmission recording parameters RETX_COUNT1 of RLC SDU segment 1 reaches default maximum weight
Number is passed, then indicates that rrc layer has reached default maximum retransmission；If the corresponding re-transmission recording parameters of RLC SDU segment 2
RETX_COUNT2 reaches default maximum retransmission, then indicates that rrc layer has reached default maximum retransmission；If RLC SDU piece
3 corresponding re-transmission recording parameters RETX_COUNT3 of section reach default maximum retransmission, then indicate that rrc layer has reached and preset most
Big number of retransmissions.
As seen from the above-described embodiment, in the embodiment, the RLC SDU segment retransmitted can be needed individually to distribute weight to be multiple
Passing recording parameters can be by the corresponding re-transmission recording parameters of the RLCSDU segment when retransmitting any RLC SDU segment again
